Claims

[Scope of utility model registration request]

In a refrigeration air conditioner equipped with a water-cooled condenser that exchanges heat of refrigerant gas supplied from a refrigerant compressor via a discharge pipe, a liquid reservoir section provided at a lower part of the condenser and a middle part of the discharge pipe are provided. A bypass pipe branched from the liquid storage part and connected to the liquid reservoir part, and a valve switching pressure value is set at a branch part of the bypass pipe in the discharge pipe, and the pressure of the refrigerant gas flowing through the discharge pipe is set at the branch part of the bypass pipe in the discharge pipe. When the pressure of the refrigerant gas is higher than the valve switching pressure value, the bypass piping is shut off and the discharge piping is fully opened, and when the pressure of the refrigerant gas is lower than the valve switching pressure value, the bypass piping is fully opened and the discharge piping is fully opened. and a pressure control valve that shuts off the condenser side of the refrigeration and air conditioning system.
