Illustration Name Function
Compressor
It is key part of air conditioner which
inhales the gas with low temp and low
pressure, then compress it to be the
gas with high temp and high pressure
and finally discharge it.
Heat Exchanger
The heat exchange between
refrigerants and flowing air can be
realized.
4-way valve
改变制冷剂流向,实现制冷制热之间的
转换。
It can change the flow direction
of refrigerants so that the switch
between cooling and heating can be
realized.
Electric
expansion valve
It is throttling gear which turn the high
pressure and liquid refrigerants to be
low temperature vapor
Electromagnetic
valve
It is controlled by strong current. It is
opened when it is energized and it is
closed when deenergization.
High/low pressure
switch
When the high/low pressure of the
system is higher/lower than a specified
value, it will work as a protection.
Oil separator
It is between discharge vent of
compressor and inlet of condensator
which separates the gas of refrigerants
from lubricants of compressor.
Gas-liquid
separator
It is between outlet of condensator and
suction vent of compressor which is
used for separating refrigerants.
