In general, heating and cooling heat pump systems are characterized by selective bidirectional flow of refrigerant.
During the summer season, the heat from the high pressure side (condenser) is used to provide heating and hot water.
During the cooling season, ambient heat absorption at the low pressure side (evaporator) can be used to provide cold air.
To ensure that
Such heating and cooling heat pump system has various structures depending on the application environment.
But basically 4 compressors, condenser, expansion valve, evaporator
The refrigerant in the system consists of the elements from the compressor to the condenser and from the condenser to the expansion valve.
Cycles from the expansion valve to the evaporator and from the evaporator back to the compressor.
And this cycle uses the second law of thermodynamics to cause the compressor to
High heat source with high temperature by absorbing heat from low heat source by performing positive work
It aims to transfer heat to (高 熱源).
At this time, the refrigerant is evaporated at a low temperature in the evaporator to absorb the surrounding heat, the compressor
In the low pressure gas flowing from the evaporator to compress the high pressure gas
It is heated up and sent to a condenser, and the condenser is heated at a high temperature from the compressor.
Heats the pressurized gas and hot water flowing from the hot water tank to heat it up.
It is phase-converted to medium temperature liquid refrigerant and sent to the expansion valve.
And, the expansion valve expands the medium-temperature liquid refrigerant flowing from the condenser
