ABSTRACT:
An air conditioning and refrigeration system includes a compressor, a four-way valve, two delivering guide pipes joined to two lateral sides of the four-way valve, two thermal compensation devices and two heat exchangers. Even if the air conditioner is a window type in association with a rotary compressor, the purpose of slow running with fast temperature reduction can be reached by means of doubling refrigerant filling and flow process regulation. Meanwhile, hi/lo pressure ratio 4:1 (cool room) or 8:1 even higher (warm room) is the most novel design of the air conditioner and it is capable of secure the indoor comfort. Besides, in case of the present invention being applied to the refrigeration system, the four-way valve inverse direction of the refrigerant being changed to enhance the efficiency thereof without using tungsten filament for defrosting.
