CONTROLLING REFRIGERANT FLOW IN AUTOMOTIVE AIR CONDITIONER

摘要

A refrigeration circuit is disclosed, which includes a subcooling control valve (12) and a decompression device (13). The subcooling control valve (12) controls the flow amount of refrigerant depending upon a detected subcooling value. The decompression device (13) controls changes of the flow amount of refrigerant. Therefore, the refrigeration circuit can control the flow amount of refrigerant and prevent the occurence of hunting phenomenon.
