Patent number: RE42908Abstract: The internal heat exchanger 7 is provided which exchanges heat between the refrigerant of low pressure and the refrigerant of high pressure, and the pre-load adjusting mechanism of the expansion valve 5 is abolished. Due to the above structure, the refrigerant flowing into the expansion valve 5 is cooled in the internal heat exchanger 7, and enthalpy of the refrigerant flowing into the evaporator 6 is reduced. On the contrary, the refrigerant sucked into the compressor 1 is heated. Accordingly, a difference in enthalpy between the refrigerant at the inlet and the refrigerant at the outlet of the evaporator 6 can be made large, and the heat absorbing capacity of the evaporator 6 can be enhanced, and further it becomes possible to give the degree of superheat to the refrigerant sucked into the compressor 1. Therefore, even if the pre-load adjusting mechanism is abolished, the vapor-compression-type refrigerating machine can be stably operated.Type: GrantFiled: November 21, 2005Date of Patent: November 15, 2011Assignee: Denso CorporationInventors: Shigeki Ito, Teruyuki Hotta, Yasushi Yamanaka
