摘要： PROBLEM TO BE SOLVED: To solve the problem that in a refrigerant circuit having a compressor, a condenser, a decompression device, and an evaporator annularly connected by piping in an air conditioner for air-conditioning a low temperature show case installed in a store such as a convenience store or for air-conditioning a store, the COP (Coefficient of Performance) is better when the high pressure side pressure of the compressor is low, but because the condensation pressure when the outside air temperature is low becomes remarkably low and the pressure difference between the high pressure side and the low pressure side becomes small, a refrigerant does not flow even when an expansion valve operates.
SOLUTION: In the refrigerating cycle device having the refrigerant circuit, when the outside temperature is low, capacity of the compressor and/or condensation capacity of the condenser is controlled so that the pressure difference between the low pressure side pressure and the high pressure side pressure of the compressor is a set value or within a set range.
