2.Functionings&principles
A low-pressure liquid refrigerant is vaporized in the heat pump's evaporator and passed into the
compressor. As the pressure of the refrigerant increases, so does its temperature. The heated
refrigerant runs through a condenser coil within the storage tank, transferring heat to the water
stored there. As the refrigerant delivers its heat to the water, it cools and condenses, and then
passes through an expansion valve where the pressure is reduced and the cycle starts over.

1. Compressor
The compressor is to effect a low-temperature low-pressure evaporator refrigerant
vapor sucked and compressed into high temperature and pressure of the superheated
vapor, and then discharged to the condenser heat exchanger.

2. Evaporator
Evaporator effects: it makes the liquid refrigerant absorbs heat and is evaporated into
steam.
3. Condenser
A condenser: high-temperature high-pressure refrigerant vapor is condensed into
liquid, during condensation, the refrigerant vapor discharge heat, the heat is absorbed
by the heating medium.
4. Thermal expansion valve:
The refrigerant passes through the thermal expansion valve, the pressure from the
condensing pressure is reduced to the evaporation pressure, part of the refrigerant will
evaporate into gas in the throttling process.

5. Filter
It’s interior has a filter and desiccant, the desiccant absorbs moisture from the
refrigerant, the filter can filter out impurities in the refrigerant.

6. High Voltage Switchgear
High-voltage switch is to prevent excessive pressure in the system, thus affecting the
life of the system components, high-pressure of the high-voltage switch is 2.8MPa.

7. Service valve
Service valve is mainly used for filling refrigerant, after removing the nuts, it contains
a valve needle, sales staff can vacuum infusion refrigerant from here.

8. Fan
It forced air through the duct, and then flows through a heat exchanger to improve
heat transfer efficiency of the heat exchanger.
