Patent number: 8157184Abstract: A first expansion valve is provided in an outdoor unit, and a second expansion valve is provided in an indoor unit. A pipe line connects a first joint pipe of the first expansion valve and a second joint pipe of the second expansion valve. When a refrigerant flows in from the second joint pipe and flows out from the first joint pipe, the first and second expansion valves are in a full open state due to pressure of the refrigerant. When the refrigerant flows in from the first joint pipe and flows out from the second joint pipe, the first and second expansion valves are in semi-closed state (flow rate controlling state). In a cooling mode, the second expansion valve expands the refrigerant just before an indoor heat exchanger, and in a heating mode, the first expansion valve expands the refrigerant just before an outdoor heat exchanger. In both heating and cooling mode, a large amount of refrigerant flows through the pipe line to reduce pressure loss.Type: GrantFiled: December 1, 2010Date of Patent: April 17, 2012Assignee: Kabushiki Kaisha Saginomiya SeisakushoInventors: Takahito Hayashi, Hideki Sekiguchi, Yutaka Kaneko, Tamami Fukuyasu, Takashi Hirakawa
