するスクリユー冷凍機。 A slide valve that forms part of the casing that houses the screw rotor. A piston directly connected to this slide valve is housed in a cylinder chamber, and the pressure in the left and right chambers of the piston is increased or decreased, and the slide valve is moved continuously. In a device that performs capacity control,
The slide valve extracts pressure from the piston position corresponding to the intermediate load position, and the slide valve extracts pressure from the piston position corresponding to the minimum load position, engages both with a differential pressure switch, and detects the compressor load from the detected pressure. A screw-through refrigerator characterized by controlling an expansion valve.
