ABSTRACT:
The refrigeration apparatus according to the invention has a main refrigeration line comprising a compressor, a condenser which are installed outdoor, and a decompression device, an evaporator and a refrigerant flow rate control valve which are installed indoor, all connected in a loop. The main refrigerant line is provided with an auxiliary refrigerant line that connects the input side of the decompression device in the main refrigerant line with the inlet side of the compressor via a bypass valve. The lowering in the suction pressure of the compressor is detected if it happens, and the pressure is restored by opening the bypass valve by throttling the refrigerant flow rate control valve, so that the compressor may be kept on running.
