evaporator (6) via the expansion valve (5) for compression and generates high temperature and pressure
vapor which then is cooled into liquid through the condenser (2) and dried in the receiver/drier (3), then
restrict the expansion valve and enable certain amount of refrigerant liquid to be vapored into low tempera-
ture and pressure vapor in the evaporator, meanwhile, absorb large amount of heat and perform heat ex-
change with the air sucked in by the blower, then distribute the cooled air to the vehicle compartments. Cycle
the operation until the compartments gets the desired temperature.
