摘要： PROBLEM TO BE SOLVED: To prevent liquid compression in starting a compressor by a liquid-phase refrigerant accumulated during the stop of a cooling device.
SOLUTION: A first opening and closing valve 21 and a second opening and closing valve 23 are closed during the stop of the compressor 1. The liquid-phase refrigerant flows to a compressor 1 side during the stop, but its inflow to the compressor 1 is inhibited by the first opening and closing valve 21 and the second opening and closing valve 23 to be accumulated in a third pipe conduit 8. When the compressor 1 is started, the first opening and closing valve 21 is kept in a closed state, but the second opening and closing valve 23 of a branch pipe conduit 22 is opened. A small quantity of the liquid phase refrigerant accumulated in a third pipe conduit 8 passes through a branch pipe conduit 22 of a small sectional area, and charged into a third pipe conduit 8 of a large cross sectional area. As the liquid phase refrigerant is gasified and liquefied to an atomized state 22b by decompression, and sucked into the compressor 1, the liquid compression of the compressor 1 is prevented. The first opening and closing valve 21 is opened by detecting the lowered pressure in the third pipe conduit 8 by a pressure gauge 26, and the compressor 1 is normally operated.
