2.2 Name and Main Function of Different Parts
No.
Name
Main Function
1
Compressor
Acting as the heat of water heater system, compress the
refrigerant to be high-temperature and high-pressure gas, promote
the flowing of refrigerant inside the system.
2
Oil temperature heating belt of
compressor
Under stand-by status, keep the oil temperature of compressor;
ensure the reliability for restarting the unit.
3
Pressure switch
When the pressure of refrigerant excesses the operate value of
pressure switch, it will feed back to stop the operation of unit, so as to
protect the compressor.
4
4-way valve
It is used for the transformation between heating and defrosting
of system.
5
Heat exchanger of evaporator
When the refrigerant enters into evaporator and conducts heat
exchange with air, the heat exchanger of evaporator will absorb the
energy from air for the unit.
6
Fan
Enhance the heat exchange of evaporator.
7
Defrosting temperature sensor
For defrosting inspection.
8
Electronic expanding valve
On the one hand is for throttle and depressurization of
high-pressure liquid refrigerant, ensuring the pressure difference
between condenser and evaporator; on the other hand is for
adjusting the flow volume of refrigerant entering into evaporator, so
as to adapt to the variation of heat load of evaporator and ensure
steady operation of cooling device.
9
Gas-liquid separator
For separating gas and liquid to prevent the compressor from
being operated under humid environment.
10
Double pipe condenser
The high-temperature and high-pressure gas discharged from
compressor will release heat inside the double pipe heat exchanger
to heat the water.
