Abstract

PURPOSE: To prevent a trouble due to fluid sealing and hence improve the safety of a refrigeration cycle by connecting a pipe line of a solenoid valve, a pressure regulating valve, and a check valve from a fluid receptor outlet piping part to an air side heat exchanger.
CONSTITUTION: A solenoid valve 22, a pressure regulating valve 23, and a check valve 24 are arranged on an outlet piping part of a fluid receptor 11. The solenoid valve 22 is opened as a chiller unit is interrupted. Further, the pressure regulating valve 23 is opened as predetermined pressure or more is attained. Accordingly, when the chiller unit is interrupted with fresh air temperature being high and hence pressures at the fluid receptor 11 and fluid piping parts locate frontally and rearwardly of said fluid receptor are raised, refrigerant is allowed to pass through the solenoid valve 22 pressure regulating valve 23 check valve 24, and discharged to an air side heat exchanger 3 outlet portion. During the operation of the chiller unit, the solenoid valve 22 has been closed and the refrigeration is prevented from flowing through the bypass pipe line by the check valve 24. Further, the pressures at the fluid receptor 11 and at the fluid piping part can be made predetermined pressure or less by the pressure regulating valve 23, preventing the pressure at the fluid piping part from being lowered.
