る冷蔵オープンシヨーケースの冷媒回路。 Two coolers are installed in the cold air circulation path formed inside the main case, and during cooling operation, the two coolers cool the inside of the refrigerator, and during defrosting, the other cooler operates while cooling. In the refrigerant circuit of a refrigerated open case, where high-temperature refrigerant is passed through one cooler to defrost the compressor and whose operation is controlled according to the refrigeration load, the refrigerant is sent from the compressor to the receiver through the condenser. A bypass pipe that takes out a part of the liquid from the liquid receiver and joins the refrigerant flowing back from the cooler to the compressor, and an electromagnetic valve that is inserted in the middle of the bypass pipe and is closed during the cooling operation and controlled to open and close during defrosting. What is claimed is: 1. A refrigerant circuit for a refrigerated open case, comprising: a valve; and a capacity adjustment valve inserted into the bypass pipe and opened by detecting the pressure of the refrigerant sent out from the cooler.
