5 1. INTRODUCTION In view of changing environmental conditions and climate shifts, innovative heating and cooling technologies are more important now than ever. The rising demand for effi cient systems in private households confi rms this every day. Heat pumps are more effi cient, conserve more natural resources and are also less expensive than typical standard heating systems because they make use of energy already present in nature to produce heat. ALTHERMA draws energy from ambient air, a free and unlimited resource, and uses this to achieve highly effi cient heat production with the help of innovative technology in the form of our output-regulating inverter. As a result, ALTHERMA is capable of obtaining up to two-thirds of the energy it requires from the air. The system also remains functional at temperatures around -20 C. ALTHERMA is a split system. It consists of an outdoor unit that draws in air and converts it to heat energy and a Hydrobox inside the house, via which this energy is fed into the water circuit for low-temperature radiators or fl oor heating. A domestic hot water tank can be installed optionally. ALTHERMA is available at various capacity levels, depending on the size and energy-conservation standard of the building in which it is used. With an optional cooling function, which is realised via fan coil units, a perfectly comfortable climate can be maintained year-round. 5

6 2. SYSTEM DESIGN 2.1 COMPONENTS OUTDOOR UNIT The outdoor unit extracts heat from ambient air. This extracted heat is transferred to the Hydrobox installed inside the house via the refrigerant circuit. CAPACITY EXPANSION OF THE OUTDOOR UNIT With the expanded capacity levels of 011, 014 and 016 kw, ALTHERMA systems with 1- and 3-phase outdoor units are suitable for an increased range of applications. For example, these capacity levels are suffi cient to supply new buildings with a fl oor area of approx. 350 m 2 (depending on house-standard) and are excellently suited for installation in renovated buildings with an appropriate heat distribution system. The heat pump can be used in a monoenergetic, monovalent or bivalent confi guration to achieve an optimal balance between purchase costs, operating costs and energy savings. HYDROBOX The Hydrobox inside the house transfers the heat contained in the refrigerant to the heating and hot water system. In the combined cooling and heating version of the Hydrobox, the cooling effect is achieved by lowering the water temperature as low as 5 C and running the water through fan coil units. A certain cooling effect can also be achieved via the fl oor heating. The preparation of domestic hot water is performed by automatic switching of the system from cooling and heating operation to hot water mode. HOT WATER TANK A specially designed water tank of stainless steel or enamel is also available. This tank serves to cover the hot water demand. The combination of a supplemental electric heater in the upper part of the tank and a heat pump heat exchanger in the lower part ensures that the fastest possible heating of the water is achieved while also consuming the least possible energy. An integrated function can ensure - if required - that the water temperature rises to over 70 C at least once per week to prevent any Legionella growth. 6

7 2.2 DESIGN GUIDELINES The following data are required in order to design an ALTHERMA heat pump that satisfi es the requirements: - Total heat demand - Any power supply cutoff from the energy supplier (utility company) - Supply temperature of the heating system - Heat pump operation mode TOTAL HEAT DEMAND The fi rst step in dimensioning of the heat pump is to determine the total heating demand. This is comprised of the standard building heating demand Q N and the domestic hot water heating demand Q HW. For creating an offer, it is suffi cient to approximately determine the heating load. However, for dimensioning of the heat pump, as for all heating systems, this must be calculated according to ÖNORM EN for the building and according to ÖNORM H 5056 for the hot water demand (example Austria - please respect your local standards!). Approximate determination: The heated area (m 2 ) is used as the basis for approximate determination of the heat demand. This is then multiplied with the below mentioned specifi c heat demand (only for approximate determination!). - New building 40 W/m 2 - Standard thermal insulation of the house: 60 W/m 2 - Older buildings without special thermal insulation: 120 W/m 2 Domestic hot water heat demand: For hot water production, a maximum demand of 30 to 60 litres per person per day at approx. 45 C is assumed for typical homes. This consumption corresponds to an additional heating demand of about 0.2 kw per person. Q Total = Q N + Q HW 7

8 2.2.2 INCLUSION OF POWER SUPPLY CUTOFF (HEATPUMP TARIFF) Energy suppliers frequently offer customers a reduced heat pump rate. However, this is often associated with cutoffperiods during which the heat pump is not supplied with electricity for heating. The electricity supply can be interrupted for a maximum of 2x2 hours within a 24-hour period (example - please check local situation). These interruption times can be taken into account in determination of the capacity requirements by integration of an additional factor. For heat transmitters with a high thermal mass, such as fl oor heating, smaller factors can also be applied. This factor is calculated with a simple formula. 24 h Z = 24 h - cutoff-period Example: The cutoff-period is 2x2 h per day. This yields a total cutoff-time of 4 hours. Calculating with above mentioned formula: 24 h / (24 h - 4 h) = 1.2 The table below can be used for typical cutoff-period values: Cutoff-period Z Calculated New building with fl oor heating 1 x 2 hours 1,10 1,05 2 x 2 hours 1,20 1,10 The required capacity for dimensioning of the heat pump is therefore calculated as follows: Q Heat Pump = Q Total x Z 8

9 2.2.3 SUPPLY TEMPERATURE OF THE HEAT PUMP SYSTEM Special attention must be paid to selection of the supply temperature for heat pump systems in particular since this has a direct infl uence on the energy demands of the heat pump. For example, every degree lower for the supply temperature corresponds to a reduction of up to 2.5% of the ALTHERMA energy consumption. For this reason, fl oor and wall heating are particularly well suited as heat carriers. In existing buildings with typical radiators, conversion to a surface heating system is generally not recommended. In such cases, a supply temperature of about 50 C should not be exceeded. In such cases, use a bivalent solution or install the ALTHERMA High Temperature. Certain measures, such as subsequent insulation, replacement of the windows or reduction of ventilation losses can be employed to lower the supply temperature. Another measure would be to increase the size of the heating surfaces or to use fan coil units HEAT PUMP OPERATION MODE After the heat demand has been determined, it is necessary to decide which operation mode the ALTHERMA heat pump system should use. Three options exist here: Monovalent Monoenergetic Bivalent - Only heat pump operation - Heat pump with supplemental electric heating - Heat pump and boiler The operation mode selected always also depends on the site conditions. ANNUAL LOAD DURATION CURVE The annual load duration curve of the outdoor temperature provides a good overview of the temperature conditions of specifi c regions. The temperature and the number of days over which it occurs yields an area within the diagram. This area represents the required heating energy over the course of a year. Heat demand Hours Example annual load duration curve 9

10 MONOVALENT SYSTEM The heat pump is dimensioned in that way that it covers 100% of the heat demand on the coldest day of the year. This solution is recommended for houses with extremely low energy loss and for regions with mild winters. The initial investment is higher, but the energy demand is lowest among all types of systems. Heat demand Outdoor unit Indoor unit Heat pump only Coldest day of the year Heating circuit Capacity of the heat pump 100% of the annual heat demand Covered by the heat pump Backup capacity of the heat pump Hours MONOENERGETIC SYSTEM The heat pump should be dimensioned in that way that it delivers 90-95% of the annual heat demand. The remaining 5-10% are covered by an electric heater. It is useful to select the heat pump so that it covers 60% of the heat demand on the coldest day. For most applications, it is recommended that the ALTHERMA heat pump be used as a monoenergetic system. This solution offers an optimal balance between investment costs and operating costs.

11 BIVALENCE POINT The bivalence point in the diagram describes the outdoor temperature till which the selected heat pump can cover the required heat demand on its own. BIVALENT SYSTEM Bivalent systems combine two independent heat sources: the heat pump and a typical standard heat producer. There are two types of bivalent systems: bivalent parallel and bivalent alternative. With an alternative bivalent system, the heat pump is switched off as of a specifi c outdoor temperature and the second heating system takes over sole production of the heat. In a parallel bivalent system, the additional heat producer is only active during load peaks, as in monoenergetic systems. Bivalent confi gurations are recommended in situations in which a heating system already exists. In this case, the energy consumption of the system is optimised by the installation of ALTHERMA. Existing heating system Existing heating system used only below the equilibrium point.

12 2.3 INSTALLATION INSTRUCTIONS The basic principles and guidelines for refrigeration engineering must be observed OUTDOOR UNIT ERHQ Placement > The distance between the indoor and outdoor units must be kept as short as possible. Only short and simple medium lines guarantee high effi ciency. The required minimum and maximum lengths can be found in the technical data (sections and 3.4.1). > The refrigerant piping may only be installed by qualifi ed refrigeration experts. > The indoor and outdoor systems with gas and liquid line must be professionally installed with thermal insulation. > The wall penetrations and the protective conduit for the connection lines must be run without direction changes, professionally installed and sealed. Installation site > The foundation of the installation site must be stable enough to hold the weight. > There must be suffi cient space at the setup site for installation, maintenance and cleaning (see dimensions Space Requirements ). Condensate (outdoor unit) > Since condensation fl ows out of the outdoor unit, a drainage bed must be built underneath, through which the condensation water can fl ow. Do not place anything under the unit that reacts sensitively to moisture. > The condensation water must be able to fl ow freely. > If the condensate connection is covered by a base plate or an area of ground, place a base with a height of at least 300 mm under the feet of the outdoor unit. > The drain pan heater tape is already installed from factory or delivered with the unit. > In cold regions, do not use a drain plug and drain hose in connection with the outdoor unit. The water could freeze and impair the function of the unit. > If use of a drain hose is unavoidable, it is recommended to install a heater tape with separate power supply and fuse to protect the drain piping from freezing. 12

Otherwise the operation noise of the outdoor unit might be transferred towards the inside of the house. > The installation site should not be next to living rooms or bedrooms due to sound emissions and should be at a suffi cient distance from neighbouring buildings. > The installation site should be selected in a way that the air discharged by the unit does not disturb the residents or neighbours. > Air short-circuits must absolutely be avoided. The required clearance for intake and discharge must always be ensured. The installation site must be selected so that the air intake and air discharge is not blocked or disrupted by snow, foliage, etc. Installation in a wall niche is not recommended (air short-circuits, sound echo). The intake air must be completely free of aggressive substances such as ammonia, sulphur, chlorine, etc. 13

14 INSTALLATION IN COLD REGIONS > Never install the outdoor unit in a location at which the intake side is directly exposed to wind. For example the unit can be installed with the intake side facing the wall. > Install a defl ector plate on the air discharge side of the outdoor unit, if necessary, to prevent exposure to wind. > In event of heavy snowfall, an installation site must be selected at which operation of the unit will not be disrupted by snow. > Install the unit at a suffi cient height above the ground so that the unit is not covered by snow and condensate can fl ow freely. > Build a base and a canopy roof. > The drain pan heater tape supplied with the outdoor units ERHQ AD8 must be installed. (Note: On the ERHQ A8/AW18, and on ERHQ A9 this is already installed at the factory) HYDROBOX EKHBH(X) a) It is recommended to mount the Hydrobox with decoupling acoustic isolation. b) Check the water quantity and the pre-pressure of the expansion vessel. The unit is equipped with a 10-litre expansion vessel that has a preset pre-pressure of 1 bar. To ensure correct operation of the unit, it may be necessary to adjust the pre-pressure of the expansion vessel and to check the minimum and maximum water volume. c) Check whether the minimum water volume in the system is at least 20 l (for proper defrosting operation, the Hydrobox must have the required minimum volume of water available in both heating and hot water mode). d) Determine based on the following tables whether the pre-pressure of the expansion vessel must be adjusted. e) Use the following table and instructions to determine whether the total water volume in the system is below the maximum permissible water volume. Height difference of the system (*) 280 l Water volume >280 l 7 No adjustment of the pre-pressure required. Required actions: The pre-pressure must be reduced, perform the calculation according to Calculating the Pre-Pressure of the Expansion Vessel Check whether the water volume is less than the maximum permissible water volume (use graph below) >7 m Required actions: The pre-pressure must be increased, perform the calculation according to Calculating the Pre-Pressure of the Expansion Vessel Check whether the water volume is less than the maximum permissible water volume (use graph below) The expansion vessel of the unit is too small for the system. (*) Height difference of the system: Height difference (m) between the highest point of the water circuit and the indoor unit. If the indoor unit is located at the highest point of the system, the height of the system is considered to be 0. 14

15 CALCULATING THE PRE-PRESSURE OF THE EXPANSION VESSEL The pre-pressure (Pg) that must be set depends on the maximum height difference (H) of the system and is calculated as follows: P g = ( H ,3 ) bar A minimum pre-pressure of 0.3 bar must always be present to avoid cavitation. Determine for the calculated pre-pressure (Pg) the corresponding maximum water volume using the following graph. Check whether the total water volume in the entire water circuit is lower than this value. If this is not the case, the expansion vessel in the unit is too small for the system and a second vessel must be connected. 2.5 Pre-pressure [bar] Maximum water volume [l] INSTALLATION AND MAINTENANCE SPACE FOR THE ALTHERMA HYDROBOX EKHBH(X) Fig.: Front view Fig.: Side view 15

74 CAPACITY TABLES The ALTHERMA by Daikin heat pump in combination with the optional domestic hot water tank provide hot water for household usage. The below mentioned date allow a proper selection of the domestic hot water tank size for maximum comfort and effi ciency. (1) Domestic hot water volume: For applications in residential buildings, the available hot water volume depends on the volume of the sanitary tank, the set temperature of the hot water and the temperature distribution within the tank. For this reason, we defi ne the equivalent hot water volume (EHWV). Definition: EHWV = The available hot water volume for applications in homes at a temperature of 40 C. 40 C is considered a suffi cient domestic hot water temperature. TANK SETPOINT TEMP. ( C) EHWV (L) USAGE PATTERN MODEST MEDIUM HIGH 150L L L Grade ++ Excessive availability of domestic hot water. + Suffi cient availability of domestic hot water. - Temporary shortage of domestic hot water can occur. Usage pattern Modest Daily demand up to 220 l typcial 2-persons usage pattern. Medium Daily demand up to 325 l typical 3 to 4 persons usage pattern. High Daily demand up to 550 l 4 to 6 persons usage pattern. (2) Heat-up time: Defi nition: Heat-up time The time required for reheating of the hot water tank to 55 C after removal of a specifi c volume of hot water at a temperature of 40 C. Note: Changes to the fi eld settings (see installation manual) can infl uence the heat-up time. TANK SETPOINT TEMP. ( C) HEAT-UPTIME FOR 150 L (BATH) MIN HEAT-UPTIME FOR 50 L (SHOWER) MIN 150L L L Conditions for testing: T a T room T start = 7 C CDB / 6 CWB, = 20 C, = 10 C, outdoor unit type: ERHQ007 (3) Efficiency of domestic hot water production: In the ALTHERMA by Daikin system both the heatpump and the electric booster heater supply the energy to produce domestic hot water.the higher the portion of energy supplied by the heat pump, the more energy effi cient the system is. Lowering the setpoint temperature increases the portion of energy supplied by the heat pump and thus the effi ciency of the system. Conditions: Outdoor temperature Room temperature Outdoor unit type Tank type Field settings 7 CDB / 6 CWB 20 CDB ERHQ l Default fi eld settings (see installation manual). 74

77 CAPACITY TABLES The ALTHERMA by Daikin heat pump in combination with the optional domestic hot water tank provide hot water for household usage. The below mentioned date allow a proper selection of the domestic hot water tank size for maximum comfort and effi ciency. (1) Domestic hot water volume: The volume of hot water available for domestic usage depends on the physical volume of the tank, on the domestic water setpoint temperature and on the temperature spreading in the tank. Therefore we defi ne the equivalent hot water volume (EHWV). Definition: EHWV = The available hot water volume for applications in homes at a temperature of 40 C. 40 C is considered a suffi cient domestic hot water temperature. TANK SETPOINT TEMP. ( C) EHWV (L) USAGE PATTERN MODEST MEDIUM HIGH 150L L L Grade ++ Excessive availability of domestic hot water. + Suffi cient availability of domestic hot water. - Temporary shortage of domestic hot water can occur. Usage pattern Modest Daily demand up to 220 l typcial 2-persons usage pattern. Medium Daily demand up to 325 l typical 3 to 4 persons usage pattern. High Daily demand up to 550 l 4 to 6 persons usage pattern. (2) Heat-up time: Defi nition: Heat-up time The time required for reheating of the hot water tank to 55 C after removal of a specifi c volume of hot water at a temperature of 40 C. Note: Changes to the fi eld settings (see installation manual) can infl uence the heat-up time. TANK SETPOINT TEMP. ( C) HEAT-UPTIME FOR 150 L (BATH) MIN HEAT-UPTIME FOR 50 L (SHOWER) MIN 150L L L Conditions for testing: T a T room T start = 7 C CDB / 6 CWB, = 20 C, = 10 C, outdoor unit type: ERHQ007 (3) Efficiency of domestic hot water production: In the ALTHERMA by Daikin system both the heatpump and the electric booster heater supply the energy to produce domestic hot water. The higher the portion of energy supplied by the heat pump, the more energy effi cient the system is. Lowering the setpoint temperature increases the portion of energy supplied by the heat pump and thus the effi ciency of the system. Conditions: Real life condition Outdoor temperature Room temperature Outdoor unit type Tank type Field settings Simulation of a daily usage based upon medium usage pattern. 7 CDB / 6 CWB 20 CDB ERHQ l Default fi eld settings (see installation manual). (4) Heat losses of domestic hot water tank: TANK EKHWE HEAT LOSSES* [KWH/24H] 150L L L 2,5 * Heat losses at 45 C between hot water in tank and surrounding air. 77
