<p><P>PROBLEM TO BE SOLVED: To suppress leakage of a refrigerant from an indoor portion and a pressure difference between forward and backward sides of a cut-off device. <P>SOLUTION: The refrigerating cycle device 1 has a leakage suppressing device 70 arranged between the indoor portion including an evaporator 40 and an outdoor portion including an accumulator 60 etc. The leakage suppressing device 70 is provided with a solenoid valve 80, one-way valve 90 and bypass 81 as the cut-off device. When the operation of the refrigerating cycle device 1 is stopped, the cut-off device is blocked. The bypass 81 allows a refrigerant flow at a minute flow rate between the outdoor portion and the indoor portion even when the cut-off device is in the blocked state. As a result, the bypass 81 avoids generation of an excessive pressure difference between the forward and backward sides of the solenoid valve 80. Even when the refrigerant is leaked from the indoor portion, the bypass 81 suppresses the leaked flow rate. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
