3. General operation of Daikin Altherma CA low temperature heat pump
The total Daikin Altherma Monobloc CA heat pump consists out of 2 loops: refrigerant and water/glycol.
A plate heat exchanger transmits the heat from the refrigerant to the water/glycol, which is then, depending on the position of the
3-way valve, used for space heating or domestic hot water.
Figure 1 - General operation of the Daikin Altherma low temperature heat pump
In the refrigerant circuit, there is a compressor which will increase the pressure and thus increase the temperature of the refrigerant
before it's being exchanged with water in the plate heat exchanger. A water pump ensures flow in the water circuit.
Operation range can be found back in the engineering data book. The requested water temperatures for space heating and
domestic hot water are delivered by the heat pump operation and, were/when necessary, by assistance of the backup heater.
