3.1 AIR CONDITIONER
A. STRUCTURE
B. PRINCIPLE OF AIRCONDITIONING
The function of air-conditioning system is to cool the
air inside the cabin and lower the humidity to promote
the convenience of operator.
The temperature shall be controlled by absorbing the
heat inside the cabin with a refrigerant and moving the
heat absorbed by a refrigerant to the air outside.
In order to enable the heat movement, the following
principle of heat generation and movement shall be
applied in the inside air-conditioning system.
a. W h e n t h e h e a t i s w i t h a s o l i d o f d i f f e r e n t
temperature, the heat moves from one to another.
In the air-conditioning system, the vaporizer absorbs
the heat from the air inside the cabin and moves it
to maintain the low temperature of a refrigerant.
b. When the gas is pressed, the temperature of the
gas increases. For the increase of pressure in the
air-conditioning system, the compressor shall be
used.
c. When the gas is cooled, this shall be concentrated
to the fluid. In the air-conditioning system, the con-
denser shall be used to cool the gas and store the
consequent fluid in the receiver drier.
d. When the fluid is injected through the hole, the con-
sequent temperature of the steam shall fall down.
Thus, the low temperature of the injected fluid shall
absorb the heat around this. In the air-conditioning
system, the refrigerant shall be injected with the
extension valve.
The main components of air-conditioning system
is as follows:
• Refrigerant
• Vaporizer
• Compressor
• Condenser
• Receiver drier
• Extension valve
