air-inlet pipe, āJā air-vent pipe and the pole sleeve. There is no connection between two pipes. The
separator is connected with the compressor by the air-inlet pipe. The filter net at the entrance of the
separator has the function of gas & liquid separating, noisy eliminating and filtering. Passing through
the air-inlet pipe, the refrigerant from the evaporator flows into the separator. Therein, the liquid
refrigerant that passing through the filter net falls to the bottom of the sleeve, and will climb to the
upper of the air-vent pipe until being absorbed by the compressor after being gasified in case of liquid
compression impact to the compressor.
ā£Heat exchanger
The evaporator and the condenser are called heat exchanger. The evaporator gasify and evaporates the
liquid refrigerant so as to absorb the heat from outside; on the contrary, the condenser releases the heat
to outside so as to low down the temperature of the gas refrigerant and liquefy it. To Cooling only
model air-conditioner, the indoor heat exchanger is evaporator and the outdoor heat exchanger is
condenser. There are two sets of heat exchanger configured in the Heat pump air-conditioner, one is
indoor type, and the other one is outdoor type, both of them are with different function because of the
different direction of their flowing circulations. During cooling mode, the indoor heat exchanger acts
as the evaporator and the outdoor heat exchanger acts as the condenser; during heating mode, indoor
heat exchanger acts as the condenser and the outdoor heat exchanger acts as the evaporator.
The indoor and outdoor heat exchangers are in the configuration of wing coil type mostly. For
promoting the efficiency of heat exchange, the patches of aluminum alloy wings are usually punched
in kinds of shapes so as to enlarge the heat exchange area, for example of Picture 2-5.
