CONSTITUTION: A refrigerant system comprises an outdoor unit(1), an indoor unit(2), a high-pressure pipe(42), a low-pressure pipe(43), a high-pressure distributing pipe(45), a low-pressure distributing pipe(46), an indoor pipe(44), a high-pressure valve(31), and a low-pressure valve(32). The outdoor unit comprises an outdoor heat exchange and a compressor(12) wherein the outdoor heat exchanger exchanges heat between refrigerant and outdoor air and the compressor compresses the refrigerant. The indoor unit comprises a plurality of indoor heat exchangers, which exchange heat between the refrigerant and indoor air.
