Name
It is the heart of the cooling system, mainly used to turn the
low-temperature, low-pressure refrigerant vapor to
high-temperature high-pressure vapor and then discharge it to
Compressor
the evaporator. The two-stage enthalpy-adding compressor is
adopted herein, which can improve the heating performance of
the unit largely.
It is one of four main components and used to turn the
Electrostatic
hi-pressure liquid refrigerant to low-temperature, low-pressure
Expansion Valve
vapor-liquid mixture and adjust the refrigerant flow rate entering
the evaporator.
It is installed at the side of the suction line, and used to prevent
Vapor Liquid
liquid refrigerant entering the compressor, which if not avoided
Separator
will lead to wet compression or even liquid slugging.
It is used the switch flow direction of refrigerant and then realize
4-way Valve
switchover between cooling and heating. It also can be used for
defrosting through the counterflow.
