3.1 Cooling Theory
There are four parts for cooling system of our portable air conditioner. They are
compressor, condenser, capillary and evaporator , which will be connected by copper, see
diagram as below.
On the working condition, first the compressor will compress the normal temperature and low
pressure refrigerant to be high temperature and high pressure air. This air will discharge to the
condenser, dispersing the heating from the lower fan motor. The refrigerant in the condenser cooled to
be middle temperature and high pressure liquid

5℃-50℃）. Decompressed by the capillary,
refrigerant expand in the evaporator, appealing the quantity of heat of the surrounding
air. Then the cooling air will blow by upper fan motor.
