却器、蒸発器を備えたスクリュー二段冷凍機において、
凝縮器入口側経路を分岐し、分岐経路を電磁弁を介在し
て、過冷却器の熱源側の出口経路に合流し、合流経路を
低段側圧縮機の吸入側および高段側圧縮機の吸入側に夫
々電磁弁を介在して選択的に接続して成り、蒸発器に負
荷がない場合は、分岐した高温冷媒ガスを過冷却器の熱
源側の流出低温ガス冷媒と合流させて低段側圧縮機へ吸
入することを特徴とするスクリュ一式二段冷凍機。In a two-stage screw refrigerator equipped with a low-stage compressor, a high-stage compressor, an oil separator, a condenser, a supercooler, and an evaporator,
The condenser inlet route is branched, the branched route is connected to the outlet route on the heat source side of the supercooler via a solenoid valve, and the merged route is connected to the suction side of the low-stage compressor and the high-stage compressor. The suction side is selectively connected to the suction side through a solenoid valve, and when there is no load on the evaporator, the branched high-temperature refrigerant gas is combined with the low-temperature gas refrigerant flowing out from the heat source side of the subcooler to generate a low-stage refrigerant. A one-screw two-stage refrigerator characterized by suction into a side compressor.
