  • Ejector-type refrigeration cycle
    Patent number: 10179500
    Abstract: An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. A length of an inlet pipe that connects a liquid-phase refrigerant outflow port of an ejector module to a refrigerant inflow port of an evaporator is shorter than a length of a suction pipe that connects a gas-phase refrigerant outflow port of the ejector module to a suction port of the compressor.
    Type: Grant
    Filed: August 7, 2015
    Date of Patent: January 15, 2019
    Assignee: DENSO CORPORATION
    Inventors: Hiroshi Kataoka, Shun Kurata, Isamu Takasugi, Haruyuki Nishijima, Youhei Nagano, Yoshiyuki Yokoyama

  • EJECTOR-TYPE REFRIGERATION CYCLE
    Publication number: 20170232822
    Abstract: An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. The ejector module is disposed outside an area that overlaps with an engine when viewed from a vehicular upper side. Further, the ejector module may be disposed outside an area overlapping with the engine when viewed from the vehicular front side, and the ejector module may be disposed outside of side members in a vehicle width direction.

  • EJECTOR-TYPE REFRIGERATION CYCLE
    Publication number: 20170225543
    Abstract: An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. A length of a suction pipe that connects a gas-phase refrigerant outflow port of the ejector module to a suction port of a compressor is set to be shorter than a length of an outlet pipe that connects a refrigerant outflow port of an evaporator to a refrigerant suction port of the ejector module. A pressure loss that occurs when a refrigerant flows in the suction pipe may be set to be lower than a pressure loss that occurs when the refrigerant flows in an outlet pipe.
