<P>PROBLEM TO BE SOLVED: To provide a system capable of manufacturing a refrigeration cycle, inexpensively, which allows reduction in power consumption by gas-liquid separation of a refrigerant. <P>SOLUTION: In the refrigeration cycle, a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, a first capillary tube 8, a gas-liquid separator 5, a second capillary tube 9, and an indoor heat exchanger 12 are connected in a ring, with the gas-liquid separator 5 connected to an injection inlet 21 of the compressor 1. By connecting the outdoor heat exchanger 3 and the first capillary tube 8 as well as the indoor heat exchanger 12 and the second capillary tube 9 by way of an expansion valve 7, the number of electromagnetic expansion valves is reduced and gas liquid separation is allowed inexpensively in the refrigeration cycle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
