Heat transfer fluid in. The heat pump collects stored Solar energy. It contains a heat transfer fluid which is a solution
of water and an antifreeze called glycol. The antifreeze mixture collects the heat from the rock and with the help of
the heat transfer fluid it is fed into the evaporator. The temperature is then approximately 0ºC.
In the evaporator, the heat transfer fluid meets the refrigerant. At this stage, the refrigerant is in a fluid state and is
at approximately -10ºC. When the refrigerant meets the zero degree heat transfer fluid it starts to boil. It then forms
a vapour, which is fed into the compressor. The temperature of the vapour is 0ºC.
The pressure of the refrigerant increases in the compressor and the vapour temperature rises from 0ºC to
approxi100ºC. The warm gas is then forced into the condenser.
The condenser transfers the heat to the central heating and domestic hot water systems. The vapour is cooled in the
condenser and becomes fluid. The pressure in the refrigerant is still high when it reaches the expansion valve.
The refrigerant pressure is lowered in the expansion valve. At the same time, the temperature also drops to
approximately -10ºC. When the refrigerant passes the valve and the evaporator it changes to vapour again. There is a
valve to regulate the flow of refrigerant.
The heat transfer fluid is fed out from the heat pump to the rock to collect new stored energy. The heat transfer
fluid leaves the heat pump to collect new stored Solar energy. The temperature of the fluid is approximately -3ºC.
