3 1. PRODUCT IDENTIFICATION CODE DOMINO EXR The DOMINO EXR units are air-water reversible heat pumps at high temperature, provided with axial fans and liquid injection scroll compressors at high efficiency. Thanks to an extended operating range that allows the machine to reach very high water production temperatures even at very low outdoor air temperatures, these units are able to operate in extreme conditions of temperature. R410a REFRIGERANT The R410a refrigerant is an ecological gas: it s not harmful to the ozone layer, it allows to obtain systems with high efficiency, it allows to contain the consumption of electrical energy and, therefore, the emission of CO2 into the atmosphere. LIQUID INJECTION SCROLL COMPRESSOR Liquid injection scroll compressors are optimized for R410a refrigerant and for heat pumps applications. They guarantee high reliability of the system, a lower number of components and reduced machine downtime thanks to liquid injection and to the sophisticated control system. The technology with liquid injection allows to raise the hot water production temperature with peaks up to 65 C to permit particular uses or antilegionella sanitization cycles; it also offers a wider opertating range: - condensing temperature and low evaporating temperature; - high outlet water temperature with low outdoor air temperature. 2

4 Outlet water temperature DOMINO EXR OPERATING RANGE IN COMPARISON : EXR RANGE VS TRADITIONAL PDC Thanks to liquid injection technology, the DOMINO EXR units have an extension of operating range for high water production temperature at low outdoor air temperatures, compared to a traditional heat pump. LIQUID INJECTION COMPRESSORS VS TRADITIONAL SCROLL COMPRESSORS Outdoor air temperature NORDIC KIT: The Nordic kit it s an obligatory accessory in case of operation at temperatures between -10 C and -20 C. The kit includes auxiliary heaters immersed in the black rows of the battery pipes, managed by the controller on the unit s in function of the outdoor temperatures (in the following pictures), hydrophil coating of aluminium fins, control panel electric heater with thermostat, a special snow-free design that prevents the accumulation of the snow on the machine frame for (sizes from 140 Z to 2145 Z), compressors sound jacket to protect and thermally insulate the compressors in case of low outdoor temperatures. 3

5 HIGH EFFICIENCY HEAT EXCHANGER The units are equipped with high efficiency evaporator stainless steeel AISI 316 brazed plate type externally insulated, complete of differential pressure switch and antifreeze protection electric heater. AXIAL FANS WITH LOW NOISE LEVEL Axial fans with speed modulating regulation, in function of the condensing and evaporating pressure, with aerofoil blades extremely silent, suitable for residential and commercial applications. HYDROPHILTECHNOLOGY The coils can be treated with HYDROPHIL surface coating that allows to improve the heat exchange performance, allowing it to maintain high air flow and higher evaporation temperatures with high energy efficiency even with low air temperature. It postpones the formation of frost thanks to a better drainage capacity of condensation. (OPTIONAL). 4

6 DYNAMIC LOGIC CONTROL Thanks to the function DYNAMIC LOGIC CONTROL, the electronic controller can manage the differential of the inlet water temperature on the basis of the speed of its variation. The function dlc works partially as a simulator of a water tank: in fact it allows to reduce the number of the compressor s starts. The main advantage of the function dlc is during the conditions of low load, that is: the compressor is switched off and the water temperature increases very slowly; in this situation the dlc is able to delay the start of the compressor by replacing itself to the thermal inertia that would be obtained from the water tank; the compressor is switched on and the water temperature decreases very quickly; in this situation the dlc is able to delay the compressor s switching off. In this way it is reached the same result that would be obtained from the water tank s thermal inertia. As result the function dlc makes possible to reduce the dimensions of the water tank, with huge advantages for the footprint of the unit. Figure 1 shows how the compressor s startups decrease by passing from a system with no tank and without dlc (1.a) to a system with Dlc (1.b) and to a system with dlc and a small water tank (1.c). It can be seen that this last solution is still the best, though the tank dimensions can be reduced. 5

7 DYNAMIC SET POINT During the heating season the outdoor temperature changes from the design temperature, and consequently the heating load of the plant changes too. It is therefore possible to adjust the outlet water temperature according to outdoor temperature by the use of a set point regulation following a climatic curve. With a bivalent outdoor temperature of - 7 C with fan coils distribution (working with an inlet water temperature of 45 C) it is possible to adjust the outlet water temperature as per a linear trend between the bivalent temperature and 15 C (temperature value to which the heating load is assumed to be zero). The curve shown is an example of possible regulation: the DYNAMIC SET POINT allows to set a regulation curve according to the design choices and to the requirements of each installation. This control allows to keep a high level of comfort and highlights the efficiency of the heat pump. The efficiency in fact increases with the decrease of the outlet water temperature thanks to a lowest condensing temperature of the refrigerant. The diagram shows the COP trend for the standard set point and the Dynamic Set Point. The DYNAMIC SETPOINT allows to adjust the working set point of the unit maximizing the comfort and the efficiency of the unit. Water production temperature trend with standard logic and Dynamic Set Point 6

8 ENERGY SAVING & AUTO ON/OFF By activating the ENERGY SAVING function and setting the daily time bands, the controller will adjust the set point value to the required value for that particular time of day. Thanks to this function, the unit will be forced to work more at certain time when the cost of electricity is lower or even to work less when there is a lower heating load. By enabling the AUTO ON/OFF function and setting the daily time bands, it s possible turn off the machine in desired hours. The electronic control gives priority to the automatic shutdown, if the two functions should be active for the same daily time band. Following are two examples to best explain the Energy saving function: 1) Energy Saving Example: industrial washing Work shift: hours 7-18; Set point work shift: 90 C; Set point out of the work shift: 65 C; Eliminated transients caused by long downtimes. 2) Auto on/off example: residential installation Request ACS: hour , ,

9 DIGITAL DEFROST TECHNOLOGY In the innovative system of electronic control and supervision by Thermocold, a new technology has been implemented to greatly reduce the number of defrosts, drastically reducing the production of negative energy to the system, inevitable during the defrost phases, during which an heat pump reverses the cycle in chiller mode. The DIGITAL DEFROST is a digital self - adaptive defrost system able to intervene only in case of formation of a consistent thickness of ice on the fins of the condensing coils. The system reduces the number of defrost cycles, by performing a control of external environmental conditions and those of evaporation unit by performing the defrosting only when it s really necessary, for example in the case of condensing coils with ice formation. Differently from traditional defrost system, using a fixed limit of evaporation temperature, the Digital Defrost technology is based on a smart algorithm that allow to: minimize the number of defrosts; minimize the time of defrost; minimize the number of unnecessary defrosts; prevent damages on the coil caused by fast ice formation; prevent unit stops due to low pressure alarm in case of fast ice formation. Variables considered by the algorithm: outdoor air temperature = Tout [ C]; evaporation temperature = Tev [ C]; time = T [min]. Thresholds considered by the algorithm: warning defrost threshold = WDT defrost activation threshold = DAT forced defrost threshold = FDT waiting time = WT. 8

10 Main features of the algorithm: 1. If the evaporation temperature drops below the warning defrost threshold, the controller starts counting until a definite time interval is reached ( waiting time ); 2. According to the outdoor air temperature value, a variable defrost activation threshold is specified (function of the outdoor air temperature) which indicates the real presence of ice on the coil. The advantage of having a defrost activation threshold as a function of the outdoor air temperature is to have a reliable prediction about the real ice presence on the coils, minimizing the probability a defrost is performed even if it is not really needed; 3. At the end of the waiting time, if the evaporation temperature drops below the defrost activation threshold, the defrost is activated. The waiting time allows to avoid a high and useless number of defrost cycles; 4. If the evaporation temperature keeps dropping down, due to an unexpected icing of the coil (before that the waiting time is reached) so as to overcome the rapid unloading threshold, the controller activates a forced part load of the circuit in order to increase the evaporating temperature. The advantages of this control are: - delay the defrost activation; - minimize unnecessary defrost cycles in case of transient operation of the circuit; 5. If the evaporation temperature is still quickly dropping down due to an unexpected icing of the coil (before that the waiting time is reached) so as to overcome the forced defrost threshold, the controller activates a forced defrost. The advantages of this control are: - minimize the risk that the unit stops running due to low pressure alarms; - minimize the risk of a coil damage caused by an inefficient defrost. 9

13 CASING From size 120 Z to 130 Z, the units are equipped with heavy gauge structure in galvanized steel. The powder paint anticorrosive treatment over the entire frame provides long lasting resistance for outdoor installation, even in aggressive environmental conditions. The front panel is easily removable for access to all internal components and for allows maintenance operations with extreme ease. Its design allows these machines to be manufactured in modular units and, at same time, it ensures a constant air flow through the finned coils and makes for easy maintenance and service. From size 140 Z to 2145 Z, the units are equipped with heavy gauge structure in galvanized steel capable to withstand mechanical stresses both during transport and operation. The high corrosion resistance, ensured by the epoxy powder base treatment and by atmospheric agents allows the outdoor installation. The construction form guarantees a perfect passage of air through the finned changer and allows accessibility to internal components in order to facilitate repair and maintenance operations. In addition it is adaptable to all the various types of installation. The total paneling of the units on the bottom side, available as optional accessory or integrated in the Nordic kit, permits the protection of the cooling circuit from weather elements such as snow, ice or rain by side panels present on carpentry. The units are also equipped with condensate drain pans equipped with integrated oversized electrical heaters to avoid the formation of ice inside it facilitating the drainage of condensation water. LIQUID INJECTION SCROLL COMPRESSORS The compressors used in these units have been properly designed to obtain a compact and reliable system able to work in applications that require an high energy efficiency. The unit is equipped with innovative liquid injection scroll compressor with optimized pressure ratio for heat pump operating mode, working with R410a refrigerant. The mass flow rate is regulated by EIV valve according to discharge temperature and the compressor rating point. These compressors ensure: - less applied parts for the system; - no need to increase compressor motor size; - lower risk of failures due to low discharge temperature; - excellent mechanical strength at high compression ratios, maintaining a discharge temperature that does not affect the life cycle of the compressor; - very high COP values, obtained thanks to fluidynamics optimization of internal passages, using high efficiency motors and introducing components of last generation; - very low noise level; - limited vibrations, thanks to accurated balancing of the masses; - reduction of pulse pressure of refrigerant. CONDENSING COILS Finned condenser coils with aluminum fins and copper pipes mechanically expanded. They are of high efficiency type with subcooled liquid refrigerant circuit integrated that allows increased power without increasing power consumption. The HYDROPHIL coating of the coil fins is an optional coil tratment available on the price list. The coil fins, due to water-repellent HYDROPHIL treatment, facilitate the condensate drainage by minimizing the risk of icing of the coils. Consequently the number of defrosts needed will be minimized. If the unit is equipped with the optional NORDIC KIT, electrical heaters are mounted on the coils, immersed in the last rows, in such a way that heat is developed around the entire pipe by increasing the conduction of heat. These electrical heaters are useful to prevent ice formation on the coils and reduce the defrosting time favoring the drainage of condensation. 12

All models are equipped with electronic device for the control of fans speed, which has the dual advantage of allowing their operation in cooling cycle, with low outdoor temperatures and greatly reducing the noise level. From size 140 Z to 2145 Z, the units are equipped with ECO-PROFILE propeller type fans, with blades statically and dynamically balanced, three-phase fan motors, closed type with external rotor and thermal overload protection and suitable for outdoor installation. Windings in F class of protection, internal protection according to VDE 0730, suitable for a temperature range from -40 to + 60 C. The ECO-PROFILE fans ensure a higher efficiency thanks to lower energy consumption compared to traditional AC motors. The lower energy consumption is guaranteed by a low rpm and "owlet" blade profile to reduce the effect of the vortices, in order to reduce the energy consumption for operating and the value of acoustic emissions, reducing average of 6 db (A) compared to common fans. The fans can be equipped with continuous speed adjustment OPTIONAL (RGF) and therefore continuous control of evaporation and condensation. DOMINO EXR units can be equipped with an optional accessory: the new generation EC-BRUSHLESS ECOPROFILE fans. It ensure a higher efficiency thanks to lower energy consumption compared to traditional AC motors. The EC motors allow therefore lower sound emissions during the air flow modulation. The blade profile has been studied to reduce noise and ensure high acoustic comfort levels.
