RTAY is a group of absorption units pre-assembled on a base, composed of GAHP-A absorption heat pumps and AY condensation boilers. The electromechanical components of all GAHP-AR absorption heat pump equipment can be reduced to the burner, fan and solution pump. This characteristic of absorption systems reduces power consumption as well as service requirements. The water-ammoniac thermodynamic employed by the GAHP-A is implemented in a hermetically-sealed (welded) circuit which does not require coolant top-ups. All absorption units and condensation boilers are exclusively for outdoors installation and can be supplied in both silent and standard versions. Principal benefits Very high : the use of absorption heat pumps yields peak efficiencies of more than 165% (for the GAHP-A); the machines are hardly affected by external temperatures, in contrast with traditional electric heat pumps. Recovery of summer-time thermal energy: using ACF60-00 HR absorption chillers with heat recovery, you can exploit the power normally dissipated to 80 heat water for applications from domestic hot water supply (with the advantage that there is no need for dedicated boilers), to swimming pool temperature control without the need for supplementary boilers, to air handler post-heating. 5

6 6 A single machine, a single system, a single fuel, a single manufacturer: one single device provides your heating or conditioning needs by recovering energy from renewable sources, while reducing the cost of creating two distinct machine rooms and simplifying the installation, management and maintenance. Reduced energy consumption: using gas directly as the appliance s power source, electrical energy consumption is drastically reduced; only of electrical power per of thermal power produced (for heat pumps). No increase in installed electrical power: given the limited electrical draw of each unit (900 W), this enables the implementation of heat pump systems without significantly increasing the overall electrical consumption of the plant. This enables the construction of more simple electrical circuits and also means that the power supply contract need not be changed. It also means that UPS systems can be installed using smaller emergency generators. Stable operation in extreme external temperatures: even -20 in outdoors installations, the GAHP-A unit guarantees efficiencies greater than 100%, and can thus be used to advantage even in especially cold locations without the need for backup systems based on boilers or electrical heaters. No indoors footprint: the indoors installation typical of traditional refrigeration plants is not required, so that the indoors of the building can be dedicated to more rational and profitable uses. Power step operation: Since the installation is dimensioned for the design conditions, it may happen that in actual operation one may have an excess of heating or cooling power. Thanks to their modular design (pre-assembled units on a base) the power delivered by the system can be adjusted gradually to meet the actual service requirements, without altering the efficiency of the system. The power modulation is achieved by switching the individual modules on in casacade so that up to five power steps are available; this eliminates frequent changes in operation and thus saves fuel consumption. This modular operation is controlled by the digital control panel (DDC) provided with the unit. Continuous service: the use of a pre-assembled group of units with cascade control is a guard against plant shutdowns. Indeed, even during malfunctions and maintenance of a single unit, the other unit will continue operating normally, thus providing uninterrupted service. Constant energy efficiency: thanks to the almost static operation of absorption units and the completely sealed circuit, coolant losses are completely eliminated along with the resulting degradation of refrigeration performance, as well as the need to top the circuit up. Continuous heating service even during defrost cycles: the formation of ice on the external finned array which occurs in certain operating conditions, automatically starts the defrost cycle which takes a few minutes to complete, during which the unitcontinues providing heat to the internal environment at 50% output, with increasing thermal or electrical energy consumption.

One should also bear in mind that operation in conditioning mode normally results in more significant pressure drops, since the fluid temperatures are lower. For the same reason, the pressure drop for AY condensing heating modules is given for the least favourable conditions, in other words, when the machine is started with cold water (20).

81 Design Manual Pre-assembled unit (LINK) 2 SIZING AND CHECKING GAHP-A SYSTEMS 2.1 DESIGN PARAMETERS The principal design parameters are the G.U.E. (Gas Utilization Efficiency) for the summer and winter and the heating and cooling powers, measured at each unit composing teh heat pump unit at design conditions. G.U.E. is the ratio between the useful heating power and the actual thermal capacity. The G.U.E. in the winter of the GAHP-AR and GAHP-A absorption heat pumps is a direct function of the temperature of the water at the condenser inlet Thr (plant return temperature) and the external air temperature Ta. The G.U.E. in the summer of the GAHP-AR and GAHP-A absorption heat pumps and the ACF chiller is a direct function of the temperature of the water at the evaporator inlet Tcr (plant return temperature) and the external air temperature Ta. Obviously, the heating and cooling powers delivered by the units, qh and qc, are also functions of the temperatures Thr, Tcr and Ta, which, together with the thermal differential T f the vector fluid are assumed as design parameters. The thermal differential of the vector fluid is set to 10 in the winter and 5 in the summer. In heating mode, the minimum and thermal differentials are equal respectively to 6 (corresponding to a flow rate of 5000 l/h at the thermal power) and 22 (corresponding to a minimum flow rate of 1400 l/h at the thermal power). In conditioning mode, the minimum and thermal differentials are equal respectively to 4,5 C (corresponding to a flow rate of 3200 l/h at the thermal power) and 10 (corresponding to a minimum flow rate of 1500 l/h at the thermal power). Given the value of T the values of Thr and Tcr are given automatically by the desired temperature of the water in delivery to the plant, Thm and Tcm. Once these values have been determined, simply use the heating and cooling efficiency tables in paragraph 2.2. These tables give, for each condenser return temperature Thr and Tcr, the value of the heating power qh and cooling power qc of the absorption units as a function of the external air temperature Ta. Another parameter which should be borne in mind is the condenser return temperature Thr max, set to the value of 50 (55 for GAHP-A HT versions). 2.2 DESIGN PARAMETERS TABLE FOR THE INDIVIDUAL UNITS COMPOSING THE LINK Table 2.1 Unitary heating power GAHP-AR UNITARY HEATING POWER GAHP-AR EXTERNAL AIR TEMPERATURE (Ta) WATER DELIVERY TEMPERATURE (T hm ) WATER RETURN TEMPERATURE (T hr ) q h [] q h [] q h [] q h [] q h [] q h [] q h [] ,30 26,50 25,70 24,90 24,90 24,60 24, ,54 26,75 25,95 25,16 25,08 24,77 24, ,78 26,99 26,21 25,42 25,26 24,94 24, ,02 27,24 26,46 25,68 25,44 25,11 24, ,26 27,49 26,71 25,94 25,62 25,28 24, ,50 27,73 26,97 26,20 25,80 25,45 25, ,98 28,15 27,33 26,50 26,04 25,70 25, ,46 28,57 27,69 26,80 26,28 25,95 25, ,94 28,99 28,05 27,10 26,52 26,20 25, ,42 29,41 28,41 27,40 26,76 26,45 26, ,90 29,93 28,77 27,70 27,00 26,70 26, ,53 30,44 29,36 28,27 27,47 27,20 26,93 81

99 Design Manual Pre-assembled unit (LINK) 3 PLANT DESIGN 3.1 GENERAL DESIGN CRITERIA Types of plant Absorption units can be used effectively with all types of hydronic heating and conditioning plant. Note, however, that since these systems are of very high efficiency, it is advisable to evaluate the use in the winter of vector fluid temperatures Thm in the medium to low range, in other words, in the range to The use of medium to high temperature in the range to 50-60, or even with peaks of 65 (for the GAHP-A version HT), should be reserved for plants equipped with not particularly efficient heat delivery units, for which it is essential never to drop below a delivery temperature of 50. To this end, we note the option of reducing the delivery temperature to radiators in three situations: a) increased hours of operation of the heating system; b) reduced energy requirement of the building (improved building insulation); c) modified radiators (increased exchange surfaces). Inertial volume The inertial tank, although specifically required, can be usefully included in the circuit as a thermal energy accumulator when the water delivery temperature is less than or equal to 50, thus reducing the number of ignition cycles of the units composing the system. The volume in litres of the inertial tank can be determined using the following formula, in which t is the accumulation time in seconds, Qs is the heating power in transferred to the accumulation tank in the time t, ρis the density of the vector fluid in use, Cp is the specific heat of the water (4.187 kj/kg K) and T is the thermal differential of the vector fluid expressed in degrees Kelvin (K). A simple way of determining the power Q s, is to select the minimum seasonal load factor F c and apply it in the following formula: Where the heating power Q h is the heating power delivered by the installed unit. Fc is the minimum seasonal load factor calculated as follows: where: Ti is the internal air temperature of the heated rooms Ta is the design external temperature Production of domestic hot water Domestic hot water (DHW) can be produced by pre-assembled units, in a variety of types of plant. In the RTAR and RTCR configurations, which do not include AY condensing modules nor ACF HR chillers with recovery circuit, the production of DHW can only be done in winter 99

100 operation mode and in the context of the condenser return temperature (50). One should thus implement an accumulation system with temperature close to the service temperature (e.g. 45) or a system with heat exchanger at the same working temperature. In any case, a supplementary system should be installed (second coil), to provide hot water during the summer, when the heat pump cannot provide heating power. Such equipment should also provide a thermal shock cycle for the anti-legionella service. In Figure 3.1 Schematic for the use of a single GAHP-AR for production of domestic hot water at max we give an example of an RTCR SC (without circulators) combined with an air conditioning and domestic hot water production plant with accumulator. The heat pump, when DHW production is not required, sends the vector fluid to the plant at the requested conditions of use. When the boiler requires power for domestic hot water production in the winter the RB100 system interface, supplied by Robur, in combination with the DDC, raises the unit s setpoint to satisfy the temporary request from the boiler. A three-way mixer valve controls the delivery temperature to the radiator coils. Figure 3.1 Schematic for the use of a single GAHP-AR for production of domestic hot water at max 45 In the schematic given in Figure 3.1 Schematic for the use of a single GAHP-AR for production of domestic hot water at max the represented components have the following meanings: 1 pressure gauge; 2 flow regulator valve; 3 water filter; 4 check valves; 5 internal circuit constant rate pump; 6 external service circuit constant rate pump; 7 three-way regulator/mixer valve; 8 heating system services; 9 DHW production external circuit constant rate pump; 10 boiler for DHW production; 11 direct digital controller DDC; 12 RB100 system interface. In the RTAH and RTHF configurations, which do not include AY condensing modules but do include ACF HR chillers with recovery circuit, the production of DHW can be done in both winter operation mode (for the RTAH units) and in the summer. In winter operation, the parameter to be considered is the condenser return temperature (50). In the summer, the heat recovery circuit of the ACF HR chillers can be used to produce heating power (with the thermal efficiency indicated in 50 Table 2.20 Unitary recoverable heating power ACF version HR 96) for use in producing domestic hot water, either directly or by preheating. The choice depends on the temperature (and consequent flow rate, since the heating energy delivery is determined by the unit s ambient conditions) at which the energy source, provided free of charge by the unit, is to be exploited. It is thus possible to implement an accumulation heating system with temperatures close 100

101 Design Manual Pre-assembled unit (LINK) to those in actual use (e.g. 45) or a system with preheating and subsequent reheating to the temperature of use by a conventional boiler or solar panels. IN any case, an alternative system must be provided (second coil powered by a conventional boiler or equivalent), to provide the DHW service when the absorption units are switched off or in use for conditioning, or when the ACF HR chiller is not active and thus cannot provide recovery heat. Such equipment should also provide a thermal shock cycle for the anti-legionella service. In Figure 3.2 Plumbing schematic for use of recovered thermal energy in domestic hot water preheating in the summer 101 we give an example of an RTAH CC (with circulators) combined with an air conditioning and domestic hot water production plant with accumulator and double coil. In the winter, the heat pump, when DHW production is not required, sends the vector fluid to the plant at the requested conditions of use. When the boiler requires power for domestic hot water production the RB100 system interface, supplied by Robur, in combination with the DDC, raises the unit's setpoint to satisfy the temporary request from the boiler. A three-way mixer valve controls the delivery temperature to the radiator coils. During the summer, the controller will give priority to the ACF HR chillers so as to provide the heating power required for DHW pre-heating, which is supplemented, when necessary, to achieve the design conditions at the accumulator outlet and for execution of the anti-legionella thermal shock cycle. Figure 3.2 Plumbing schematic for use of recovered thermal energy in domestic hot water preheating in the In the schematic given in Figure 3.2 Plumbing schematic for use of recovered thermal energy in domestic hot water preheating in the summer 101 the represented components have the following meanings: 1 pressure gauge; 2 flow regulator valve; 3 water filter; 4 check valves; 5 internal circuit constant rate pump; 6 external service circuit constant rate pump; 7 three-way regulator/mixer valve; 8 heating system services; 9 DHW preheating circuit constant rate pump; 10 double coil boiler for DHW production; 11 direct digital controller DDC; 12 RB100 system interface. In the RTY, RTRC, RTYR, RTYF and RTAY configurations, which include AY condensing modules but do not include ACF HR chillers with recovery circuit, the production of DHW can be done in any operating mode, thanks to the presence of the condensing modules. In this case, it is advisable to use the 4-pipe versions, since this ensures DHW production independently of the operation of the absorption units. In this condition one can supply an accumulation boiler with water at the desired temperature (the only limit is constituted 101

102 by the boiler return temperature, which is equal to 70), and thus easily reach temperatures which make any further anti-legionella treatment unnecessary. In Figure 3.3 Hydraulic schematic for a mixed heating and DHW production system 102 we give an example of a single RTYR CC (with circulators) unit in the 4-pipe version combined with a heating system with radiant panels and domestic hot water production plant with accumulator. Figure 3.3 Hydraulic schematic for a mixed heating and DHW production system In the schematic, the represented components have the following meanings: 1 pressure gauge; 2 flow regulator valve; 3 water filter; 4 shut-off valve; 5 internal circuit constant rate pump; 6 external service circuit variable rate pump; 7 2-way regulator valve; 8 heating system services; 9 hot water production external circuit constant rate pump; 10 boiler for domestic hot water production; 11 diverter valve for excluding the AY boiler; 12 Direct Digital Controller; 13 RB100 system interface. The present schematic does not include the ISPESL ramps inasmuch as they are nor required for AY condensing boilers. The plant represented in Figure 3.3 Hydraulic schematic for a mixed heating and DHW production system 102, provides not only normal heating and conditioning services, but also DHW production in all seasons of use by one of the condensing boilers in the circuit. When needed, when the DHW boiler requires it, the RB100 system interface actuates the diverter valves (position 12) and, when a limit signal notifies the interface that deviation of flow towards the boiler has been completed, it varies the setopint (if required) of the single Robur AY condensing boiler used for the operation, which is disconnected from the heating circuit until the DHW production service has terminated. In the RTRH and RTYH configurations, which include both AY condensing modules and ACF HR chillers with recovery circuit, the production of DHW can be done in any operating mode, thanks to the presence of the condensing modules. In summer mode, the recovered heat can be used for pre-heating the water in the accumulation boiler, thus reducing module trip cycles and, consequently, running costs. In this case, it is advisable to use the 6-pipe versions, since this ensures DHW production independently of the operation of the absorption units, while also allowing the simultaneous use of the recovery circuit hot water in other ways (DHW pre-heating, DHW production for swimming pool heating, etc.). In this condition one can supply an accumulation boiler with water at the desired temperature (the only limit is constituted by the boiler return temperature, which is equal to 70), and thus easily reach temperatures which make any further anti-legionella treatment unnecessary.

Figure 3.4 Hydraulic schematic for a mixed heating and DHW production system with summer pre-heating In the schematic, the represented components have the following meanings: 1 pressure gauge; 2 flow regulator valve; 3 water filter; 4 check valves; 5 AY boiler internal circuit constant rate pump; 6 external service circuit variable rate pump; 7 2-way regulator valve; 8 heating system services; 9 heat pump internal circuit constant rate pump; 10 recovery hot water circuit constant rate pump; 11 boiler for DHW production; 12 diverter valve for excluding the AY boiler; 13 direct digital controller DDC; 14 RB100 system interface. The present schematic does not include the ISPESL ramps inasmuch as they are nor required for AY condensing boilers. The plant represented in Figure 3.4 Hydraulic schematic for a mixed heating and DHW production system with summer pre-heating 103 provides not only normal heating and conditioning services, but also DHW production in all seasons of use by one of the condensing boilers in the circuit. When needed, when the DHW boiler requires it, the RB100 system interface actuates the diverter valves (position 12) and, when a limit signal notifies the interface that deviation of flow towards the boiler has been completed, it varies the setopint (if required) of the single Robur AY condensing boiler used for the operation, which is disconnected from the heating circuit until the DHW production service has terminated. Characteristics of the plant water supply Robur units, by their very nature, do not require evaporator towers to operate. There is thus no need for topping up the water circuit. Furthermore, for the same reason, there are no special requirements or restrictions on the plant water quality, so that one need only refer to the normal values adopted for the physical and chemical properties of vector fluids in traditional conditioning and heating systems. You need only observe established standards regarding the treatment of water for heating/cooling systems. The optimal chemical and physical specifications for the water are given in Table 3.1 Chemical and physical parameters of water 103.

The units may not under any circumstances be installed indoors. No obstruction or overhanging structure (protruding roofs, eaves, balconies, ledges, trees) may obstruct the flow of air from the top of the appliance, nor the combustion fumes exhaust. Do not install the units in the immediate vicinity of flue outlets, chimneys or other such features, so as to prevent warm or polluted air from being drawn in by the fan via the condenser. In order to function correctly the units must use clean air from the environment. They must be installed in such a way that the exhaust fumes outlet is not in the immediate vicinity of any external air inlets of a building. Observe established standards in regard to the discharge of fumes. If the units are to be installed in the vicinity of constructions, make sure that it is out of the way of water dripping from gutters or similar sources. The absorption units are homologated for connection of their combustion products evacuation pipe to a flue for direct connection to the exterior of type B23 and B53. Each GAHP-AR module is equipped with a fitting of diameter Ø 80 mm while each AY condensing module is equipped with a fitting of diameter Ø 80 mm (each of them are fitted with gaskets). If the type of installation or established legislation requires combustion products to be conveyed away, refer to the instructions given in Paragraph 1.13 PRESSURE DROPS 76 for the correct dimensions of the duct in relation to the characteristics of each module composing the unit. The fumes flue, if present, and the fumes duct, must be dimensioned for operation with natural or forced draw in relation to the residual head available at the flue outlet. In the case of condensing units (AY condensing and GAHP-A), the flue and its fumes duct must be constructed in polypropylene and the high residual head (80 Pa) makes it possible to find an optimal discharge solution without difficulty. Each unit which has more than 2 condensing units is equipped with a condensation collection and conveyance system, which must be connected to the discharge circuit by the installer If local legislation permits, it can be discharged directly into the sewers, otherwise a system to neutralise the condensation before disposal must be installed. Depending on the type of installation it may also be necessary to install a condensation return pump, available from Robur. Plumbing plant and gas circuit The sizing of the plumbing pipes and pump must guarantee the water flow required for correct operation of the pre-assembled unit (for calculation of pressure drops in pre-assembled units, refer to Paragraph 1.13 PRESSURE DROPS 76). The hydraulic plant may be created using pipes in stainless steel, black steel, copper or crosslinked polyethylene for heating/cooling plants. All water pipes and pipe connections must be adequately insulated in accordance with current regulations, to prevent heat loss and the formation of condensate. 104

105 Design Manual Pre-assembled unit (LINK) When rigid pipes are used, in order to prevent the transmission of vibrations, we recommended connecting the water inlet and outlet of the appliance with antivibration joints. When filling the hydraulic circuit, ensure the minimum water content in the plant, and add, in case of outdoors installation, to the plant water (free of impurities) a quantity of inhibited monoethylene glycol in proportion with the minimum winter temperature in the installation zone (see Table 3.2 Percentage of monoethylene glycol 105). To prevent icing inside the circuit, the units are equipped with antifreeze equipment. This device (antifreeze function) starts the external water circulation pump (if controlled by the unit) and, if necessary, the burner (in heating mode). It is therefore necessary to ensure a continuous supply of electricity and gas to the appliance throughout the whole of the winter period. If it is not possible to ensure a continuous supply of electricity and gas to the appliance, use glycol antifreeze of the inhibited monoethylene type. If glycol antifreeze is to be used, DO NOT USE galvanised pipes, as they are potentially subject to corrosion in the presence of glycol. Table 3.2 Percentage of monoethylene glycol 105 following, we give the approximate freezing temperature of the water and consequent increased drop in pressure of the appliance and system circuit as a function of the percentage of monoethylene glycol employed. This table should be taken into account for the sizing of the pipes and the circulation pump (for calculation of internal pressure drops of the appliance, refer to Paragraph 1.13 PRESSURE DROPS 76). Nevertheless, it is advisable to consult the technical specifications of the monoethylene glycol used. Table 3.2 Percentage of monoethylene glycol % of MONOETHYLENE GLYCOL WATER FREEZING POINT TEMPERATURE PERCENTAGE OF INCREASE IN PRESSURE DROPS -- 6% 8% 10% 12% 14% 16% LOSS OF EFFICIENCY OF UNIT -- 0,5% 1% 2% 2,5% 3% 4% Technical data for filling the hydraulic circuit The pressure of the gas supplied by the mains must be within the range of 17 and 25 mbar for natural gas (G20), and between 25 and 35 mbar for LPG (whether G30 or G31). The gas supply system must be correctly rated for the capacity required by the appliance and must be equipped with all safety and control devices prescribed by current regulations. Clean the plant of any waste or process residue before commissioning the units, to prevent the filters blocking and reducing the circulation of water. 3.3 POSITIONING THE PRE-ASSEMBLED UNIT Lifting and positioning Pre-assembled units can be installed at ground level, or on a terrace or roof (if they are able to sustain its dimensions and weight, see the section 1 OVERVIEW AND TECHNICAL CHARACTERISTICS 5 for the unit in question). The hoist and all accessory equipment (braces, cables, bars) must be of adequate dimensions in relation to the load to be lifted. 105

106 Supporting base Always position the appliance on a flat level surface that is made of fireproof material and able to sustain the weight of the appliance itself. During winter operation, the appliance, on the basis of temperature and humidity conditions of the outside air, can carry out defrosting cycles that cause the layer of frost/ice on the fan coil to melt. Take this possibility into consideration, adopting appropriate measures (for example: a containing step and channelling of water into a suitable drain) in order to prevent uncontrolled spread of water around the appliance and the consequent risk that a layer of ice will form (with the danger of falls on the part of passing people). Robur S.p.A. is not liable for any damages resulting from failure to observe this warning. Installation at ground level If a horizontal support base is unavailable (see also "SUPPORTS and LEVELLING" below), it is necessary to create a flat level base in concrete which is larger than the dimensions of the base of the appliance by at least mm on each side. The dimensions of the pre-assembled units are given in the section 1 OVERVIEW AND TECHNICAL CHARACTERISTICS 5. Provide a containing step and a suitable drainage channel for the water. Installation on a terrace or roof Position the appliance on a levelled flat surface made of fireproof material (see also "Supports and levelling" below). The structure of the building must be able to sustain the weight of the appliance added to that of the supporting base. The weights of the pre-assembled units are given in the Section 1 OVERVIEW AND TECH- NICAL CHARACTERISTICS 5. Make sure to install a containment area which conveys the water to a drain inlet, as well as a maintenance walkway around the appliance. Although the appliance produces only moderate vibrations, the use of anti-vibration supports (available as accessories) is especially recommended in rooftop and terrace installations in which resonance phenomena may occur. In addition, it is advisable to use flexible connections (anti-vibration joints) between the appliance and the hydraulic and gas supply pipes. Supports and levelling The appliance must be correctly levelled by placing a level on its top surface. If necessary, level the appliance with metal shims, placing them appropriately in relation to the mounts; do not use wooden spacers as these degrade quickly. Clearances Locate the appliance in such a way as to maintain the minimum specified clearances from combustible surfaces, walls or other equipment, as given in Figure Minimum clearances are necessary in order to be able to carry out maintenance operations and to ensure the correct airflow required for heat exchange with the finned coil. If special installations are required (trench, niche, etc.), consult with Robur S.p.A. for the clearances required. 106

107 Design Manual Pre-assembled unit (LINK) Figure 3.5 Minimum clearances (dimensions in mm) Evaluate the noise impact of the appliance in relation to the installation site: avoid installing the appliance in positions (corners of buildings, etc.) that could amplify its running noise (reverb effect), and always check the consequences of the intended installation position. 3.4 HYDRAULIC PLANT COMPONENTS The components described below, to be fitted in proximity to the appliance, are illustrated in the typical hydraulic plant schematics in section "6 PLANT SCHEMATICS 117": ANTIVIBRATION JOINTS in line with the water and gas connections of the appliance. MANOMETERS installed in the inlet and outlet water pipes. FLOW REGULATION VALVE (shutter or balancing) at the water inlet pipe. WATER FILTER at the water inlet pipe, mesh MIN 0.7 mm, MAX 1 mm. ISOLATION BALL VALVE in the water and gas pipes of the plant. 3 BAR SAFETY VALVE installed in the appliance outlet water pipe. EXPANSION TANK on the water outlet pipe. PLANT WATER CIRCULATION PUMP on the water inlet pipe, rated for the installation in question. Systems for BLEEDING AIR from the water pipes, located at the top of the appliance circuit. DRAIN COCK on the water pipes. PLANT FILLING SYSTEM: if automatic filling systems are used, it is advisable to carry out a seasonal check of the percentage of monoethylene glycol contained in the plant. CONDENSATION COLLECTION AND DISPOSAL SYSTEM connected to the condensation drain provided on the unit, complete with eventual neutralisation system as per established legislation and eventual condensate pump. If more than one unit is connected to a single hydraulic circuit, the following must also be installed: WATER CIRCULATION PUMP for each unit, on the water inlet pipe, with delivery towards the GAHP-WS unit, rated for the installation in question (except for units provided with independent circulators as standard - CC configuration). HYDRAULIC SEPARATOR complete with air bleeder valve and drain tap. 107

108 PLANT WATER CIRCULATION PUMP on the plant delivery pipe, with delivery towards the plant. 108

109 Design Manual Pre-assembled unit (LINK) 4 ELECTRICAL DESIGN The following specifications must be observed in the electrical power section of the plant: Power supply 400 V 3N - 50 Hz or, alternatively, 230 V 1N - 50 Hz. The electrical components used for the hookup (circuit breakers, fuses, relays, etc.) must be mounted in an external electrical cabinet located by the installer in the vicinity of the pre-assembled unit. If the plant is equipped with a hydraulic separator, take the precautions required to prevent the external circuit water freezing during the winter (for example, control the operation of the external circuit circulation pump with a lock or thermostat). N. B.: The electrical safety of the appliance is guaranteed only when it is correctly connected to an efficient grounding system, executed in accordance with current safety regulations. Do not use gas pipes to ground electrical appliances. The electrical connection schematics are given in Section "6 PLANT SCHEMATICS 117". 4.1 CONNECTIONS TO THE PRE-ASSEMBLED UNITS To hook up one or more pre-assembled units, the following will be required: A connection cable, FG7(O)R 5Gx4. An external four- or two-pole circuit breaker with 3 fuses with minimum airgap 3 mm or a thermal cutout. 4.2 CONNECTING THE CONTROLLER The pre-assembled units can be controlled with the standard accessory Direct Digital Controller (DDC). For a total cable run of 200 m and up to 5 single units connected (composing the preassembled unit), use a simple 3x0.75 mm2 shielded cable; otherwise use a CAN-BUS cable as specified by the Honeywell SDS standard, as given below: Robur Netbus (Robur, cable run 450 m). Belden 3086A (Honeywell SDS 1620, cable run 450 m). Turck 530 (Honeywell SDS 1620, cable run 450 m). Turck 5711 (DeviceNet Mid Cable, cable run 450 m). Turck 531 (Honeywell SDS 2022, cable run 200 m). 109

111 Design Manual Pre-assembled unit (LINK) 5 REGULATOR SYSTEM 5.1 DIRECT DIGITAL CONTROLLER (DDC) The fundamental component for the control and regulation of the units is the Direct Digital Controller (DDC). The Direct Digital Controller is a device which displays, on a backlit graphic LCD display of 128x64 pixels, all the status, operating and error conditions of each individual unit to which it is linked. The DDC controls water thermostating by controlling the switch-on and switch-off of the units connected to it. Each DDC is able to control up to sixteen GAHP-WS modules, beyond which another DDC must be used in combination with the first to control the system. For pre-assembled units, the DDC is standard supply (one per unit). The DDC is designed for indoors installation (ambient air temperature in the range to 0 50), mounted to an electrical cabinet in a hole measuring 155 x 151 mm. The front of the DDC mounts a graphic display on which all the parameters necessary to control, program and configure the plants managed by the DDC are shown (see detail D, Figure 5.1 Direct Digital Control (DDC) 111); a selector knob (Encoder) used to communicate with the DDC and select options, parameter settings, etc. (detail E, Figure 5.1 Direct Digital Control (DDC) 111); an RS 232 serial port for connecting the DDC to a PC (see detail SPC, Figure 5.1 Direct Digital Control (DDC) 111), used for technical service. The rear of the DDC mounts all the electrical and CAN-BUS connections required for its operation. Furthermore, it also features voltage free contacts for additional DDC on/off options using enabling signals from external regulator systems, alarm lamps and buzzers for remote installation, and contacts for connection to an ambient sensor (optional).

112 5.2 CONTROL AND REGULATION OF THE SYSTEM For the control and regulation of the system, install one or more DDC s, which serve to obtain full system diagnostics and control and regulate the operation of the system itself. In particular, they are used to set the winter-time vector fluid differential and setpoint, with the option to control either the delivery or return temperature. The above settings can be made for four daily time bands, with the option of using four different setpoints. The Robur plant concept, which also includes multiple units, has the certain benefit of enabling completely independent operation of the component modules, so as to deliver the cooling/heating power strictly required to handle the real time load, thus preventing frequent operational variations and consequent wasted fuel consumption. Installation of units in cascade, up to five power steps, is featured on the DDC. Figure 5.2 Example of winter operation power steps Figure 5.3 Example of summer operation power steps 6,5 7,0 7,5 8,0 8,5 9,0 9,5 10,0 10,5 11,0 11,5 12,0 SET-POINT SET-POINT + DIFFERENZIALE The regulation system, during the first daily power on, powers up all modules, which are then gradually switched off starting from the setpoint temperature minus the differential set on the DDC. The system does not provide for sensors on the plant delivery or return pipes, since the pre-assembled units are equipped with sensors which enable direct measurement onboard of the vector fluid temperature. 112

113 Design Manual Pre-assembled unit (LINK) 5.3 "DEFROSTING" During normal winter operation, it may happen that the finned array of the ices up with the humidity in the air. Contrary to what is the case in air-water electric heat pump appliances, the individual absorption unit of the pre-assembled unit automatically runs a defrost cycle, while continuing to provide heating to the plant (the system does not undergo cycle inversion). The on-board electronics deviate part of the flow of ammoniac originating from the generator at a temperature close to that of the finned array, thus detaching the layer of ice. The heating power required for the heating plant is still provided by a part of the flow of ammoniac which continues to be sent to the tube coil heat exchanger in which the exchange of heat with the plant water occurs 80 Tests run on systems with pre-assembled units have shown that the number of defrosting cycles does not exceed 50 per winter season and that each cycle lasts an average of 3 minutes thanks to the high condensation temperature of the ammoniac. In short, the defrosting cycles do not compromise the overall efficiency of the heat pump. 5.4 SLIDING TEMPERATURE The Pre-assembled unit (LINK) delivery/return temperature can be regulated continuously as a function of an external parameter controlled by another electronic system. In particular, it may be useful to vary the vector fluid delivery temperature as a function of the external air temperature, or another plant parameter which is significant in the application in question. This option is provided by the optional RB100 plant interface, connected by a can-bus cable to the DDC. The RB100 can receive a 0 10 V digital signal from an electronic regulator, so as to continuously modulate the delivery or return temperature. The RB100 device has the function of interfacing the requests coming from one or more external control systems with the DDC. It has the following functions: it controls the connected Robur units with a continuously variable temperature setpoint (sliding temperature) as well as domestic hot water production, which also requires actuation of the three-way diverter valves (see also Paragraph 5.5 CONTROL OF DOMESTIC HOT WATER (DHW) PRODUCTION 113). RB100 board dimensions: width 158 mm, depth 74.6 mm height mm. The weight of the component is kg and it must be mounted to the cabinet on a 35 mm DIN rail (EN 60715). 5.5 CONTROL OF DOMESTIC HOT WATER (DHW) PRODUCTION The domestic hot water production service can be provided using only the component GAHP-AR units when the system includes medium to low temperature accumulator boilers (45-48) or when the production is handled directly by suitably dimensioned heat exchangers (external circuit delivery temperature 45-48). This service is however only available in the winter, while during the summer a boiler specifically intended for this service will be required. If the plant is to be equipped with one or more absorption Pre-assembled unit (LINK) in combination with AY condensation boilers, this service can be provided at any temperature of the DHW production boilers (accumulation temperature greater than 50) and in any season, using the condensation boilers for this purpose. In this case it is advisable that the pre-assembled units be in the 4 or 6-pipe versions (the latter if an ACF HR chiller with heat recovery is also included), with the boiler fittings connected to a manifold specifically dedicated to DHW production. 113

114 In any case, in order to use absorption heat pumps to produce DHW, the controller must be equipped with a DDC and an "RB100" system interface. If GAHP-AR heat pumps are to be used for producing DHW under the above-mentioned conditions (accumulation temperature close to user temperature - max 48), the RB100 is required to raise the unit's delivery temperature, if this is not already set to the working temperature. If Robur AY condensing boilers are also to be used (4- or 6-pipe version), the RB100 module connected with a CAN-BUS cable to the DDC can be used to deviate the vector fluid flow from the latter to a heat exchanger for direct or accumulation production of DHW. This is done by directly controlling the two dedicated 3-way diverter valves (not supplied by Robur S.p.A.). Once the heating circuit has been deviated to DHW production, the RB100 module modifies the setpoint only of the Robur AY condensing boilers involved in this service. The adjustment of the DHW setpoint of the Robur AY condensing boilers can be done with an ON-OFF analogue signal originated by a thermostat, or by a 0-10 V digital signal from an electronic controller. The advantage of the RB100 unit is that there is no need to include other boilers for DHW production, so that all the Robur AY condensing units can be used, which would otherwise be kept switched off most of the time during the winter. Clearly the DHW production service has operational priority, so that if the system is operating under design conditions, the boilers dedicated to the dual service will nonetheless be switched from heating mode to DHW production for the duration of the period for which the service is required. For existing plant for which the user wishes to implement such a remote control system, the firmware must be compatible with the components - contact Robur S.p.A. presales. 5.6 REMOTE CONTROL - WISE (WEB INVISIBLE SERVICE EMPLOYEE) The WISE unit provides remote control of the major functions of the DDC and thus of the Robur units and plant controlled by the latter, over a common cellphone line equipped with WAP browser or using a point-to-point connection with a PC with a PSTN or GSM modem, so as to implement tele-control and teleassistance applications. The system is controlled by means of a web browser, while alarms are sent to the user by SMS. The WISE device is composed of: n.1 WISE device; n.1 antenna; n.1 RS232 null-modem serial cable for device configuration; n.1 WISE - DDC communications cable with phone plug connection to the rear of the DDC; n.1 CD-ROM. For existing plant for which the user wishes to implement such a remote control system, the firmware must be compatible with the components - contact Robur S.p.A. presales. 5.7 MOD BUS The DDC supports interfacing with external equipment (BMS, PLC, SCADA, etc.) via the Modbus RTU protocol. The Modbus protocol makes it possible to acquire data regarding the operation of the units and the plant controlled by the DDC (temperatures, statuses, counters, etc.). It can also acquire information regarding alarms, both current and registered in the alarms log. It can also act on the plant to set a variety of operational parameters such as unit On/Off, hot/cold inversion, setpoints, differentials, power steps, and operating time bands. The DDC implements the Modbus RTU protocol as a slave device, in the following modes: N1; E1; N2; N1; E1; N2. 114

115 Design Manual Pre-assembled unit (LINK) The default modbus address is 1, and can be configured via the DDC s display which supports the following modbus function codes: (01) Read Coil Status; (02) Read Discrete Input; (03) Read Holding Register; (04) Read Input Register; (05) Write Single Coil; (06) Write Single Register; (15) Write Multiple Coil; (16) Write Multiple Register; (23) Read/Write Multiple Register. The DDC is equipped to support broadcast messages. 115
