Function
Compressor
Through compression, the low pressure refrigerant occupies a less space.
As its pressure and temperature both rise, it becomes high pressure and
high temperature refrigerant. It is the power drive of the system.
4-way valve
It is used to change directions, the flow of refrigerant in cooling/heating.
Motor
The power drive of the fan. It enables the fan to run so as to provide
smooth currents of air for forced convection and heat exchange of
condenser and evaporator.

exchange of condenser and evaporator.
Gas liquid
separator
Installed at the suction side of compressor, it can separate the liquefied
refrigerant from the gaseous refrigerant to make sure that only gaseous
refrigerant will be sucked into the compressor. If liquefied refrigerant gets
inside the compressor, ineffective compressor or slugging phenomenon
will occur.
