REFRIGERATING SYSTEM FOR VARIABLE FREQUENCY AIR CONDITIONER, AND VARIABLE FREQUENCY AIR CONDITIONER HAVING REFRIGERATING SYSTEM

摘要

A refrigerating system (10) for a variable frequency air conditioner, and a variable frequency air conditioner having the refrigerating system; the refrigerating system (10) comprises a compressor (100), a four-way valve (600), a condenser (200), a heat exchanger (300), a throttling element (400), an evaporator (500) and a one-way valve (700); the heat exchanger (300) and the one-way valve (700) are connected between the second end of the condenser (200) and the second end of the throttling element (400); when cooling, the one-way valve (700) is closed, and refrigerant flows through the heat exchanger (300) from the condenser (200) to the throttling element (400); and when heating, the one-way valve (700) is open, and the refrigerant bypasses the heat exchanger (300) when flowing from the throttling element (400) to the condenser (200).
