Selection and Dimensioning of Heat Pumps for Heating and Cooling 1.2 1 Selection and Dimensioning of Heat Pumps for Heating and Cooling 1.1 Calculating the Heat Consumption of the Building The maximum hourly heat consumption 4his calculated according to respective national standards. It is possible to estimate the approximate heat consumption using the living space A (m2) that is to be heated: +HDW FRQVXPSWLRQ >N:@ +HDWHG DUHD Â 6SHFLILF KHDW FRQVXPSWLRQ >P @ >N: P @ T = 0.
1.3 The values specified by this method are calculated on the basis of the VDI 2078 cooling load regulations. The calculation is based on a room temperature of 27 °C, an external temperature of 32 °C and continuous operation of the cooler. 1.3 1.3.1 Checking the Operating Limits Maximum Heat Output of the Heat Pump If the heat consumption of the building is higher than its cooling requirements, the heat pump should be configured for heating operation.
Selection and Dimensioning of Heat Pumps for Heating and Cooling Examining the sufficient size of the installed heating element: The following options are then available: Total heat consumption at minimum external temperature (Design) – Heat output of the heat pump at minimum external temperature = Output of the electrical heating element, max.
1.3.2 1.3.2 Maximum Cooling Capacity of the Heat Pump If the maximum required cooling capacity of a building is already known (see also Chap. 1.2 on p. 3), it should be checked to ensure that the heat pump can supply this refrigerating capacity for the required boundary conditions. It is particularly important to check the operating limits of the particular type of heat pump used.
Generation of Refrigerating Capacity 2.2.2 2 Generation of Refrigerating Capacity 2.1 Passive Cooling with Ground Water In compliance with the VDI 4640 standard, most regions welcome a cooling of the ground water e.g. through the use of a heat pump for heating purposes. Increasing the temperature by cooling, on the other hand, is only acceptable within strict limits. 2.

Heating and Cooling with a Single System 3.3.2 3 Heating and Cooling with a Single System 3.1 Energy-Efficient Operation In the same way that national standards demand building and system-specific measures for reducing the heating energy consumption, measures should also be taken to save energy by thermally insulating buildings for the warm summer months. air, by cooling the air using a heat exchanger installed in the room or by directly cooling structural parts of the building.
3.3.2 NOTE Open windows should not be used for continuous ventilation in cooling operation for the following reasons: It increases the heat load of the room The cooling capacity is often insufficient, particularly with silent cooling There is danger of condensate forming in the ventilation area around the window.

Electrical Installation 6.4 6 Electrical Installation 6.1 Power supply Depending on the technical data of the device, the power supply of the heat pump is 230VAC/50Hz or 3-L/NPE 400VAC. A standard 3-core cable is used for single-phase devices (230 V AC). A 3-core cable is used as load connection for the heat pump (terminal strip X3) and the electrical supplementary heating (2nd heat generator) for air-to-water heat pumps is connected with a second 3-core cable.

Control and Regulation 7.1.2 7 Control and Regulation The elements of the simplified regulation of air-to-water heat pumps and brine-to-water heat pumps are identical. The controls are integrated in the unit with the brine-to-water heat pumps installed. By contrast, the air-to-water heat pumps installed outdoors are equipped with a remote controller which is normally installed inside the building. With the air-to-water heat pump LAK 10MR, the room temperature recording and regulation is 7.1 7.1.
7.1.3 7.1.3 Controller board The current operating state of the heat pump can be read by the individual LEDs on the controller board.
Control and Regulation 7.4.2 1) On = Compressor running 2) On = Brine circulating pump running 3) Off = Heat pump in "Heating" mode On = Heat pump in "Cooling" mode 8) Not used 9) On = Hot water request 4) On = Heat circulating pump running 10) Not used 5) Not used 11) Flashes during operation 6) On = Antifreeze request, the heat pump is heating 12) Flashes in case of a fault 7.3 NOTE The heat pump is blocked for 10 minutes when it is switched from heating to cooling operation.
7.4.3 temperature range between min. 10 °C and max. 40°C. The heat pump cools until the set return temperature is reached and then shuts off automatically. If the return temperature rises by 4 Kelvin above the set return temperature, the heat pump switches on again automatically. The heat pump also switches itself off if the heating water reaches a flow temperature of approx. 7 °C or the air intake temperature exceeds the upper operating limit.
Control and Regulation PAY SPECIAL ATTENTION TO: With reversible brine-to-water heat pumps, even higher brine inlet temperatures may be expected since the brine temperature could rise significantly during cooling operation in the summer. At higher heat source (brine) temperatures, the heat pump generates a significantly higher heating output which must then be transferred to the domestic water during hot water preparation.
8 8 Hydraulic Integration for Heating and Cooling Operation The generated cooling capacity is distributed using the heat distribution system which is also to be configured for distributing cold water. equipped with a dew point monitor available as a special accessory. This will halt cooling operation in the event of moisture formation. Condensate can form due to the low flow temperatures, especially in case of dynamic cooling.
