Claims

[Claims for Utility Model Registration] 1. A multi-cylinder rotary compressor having a plurality of compression elements;
In a refrigerant circuit in which a condenser and a plurality of evaporators installed in parallel are connected via piping, and a pressure reducing device is connected in series to each of these evaporators, each compression element of the multi-cylinder rotary compressor and each evaporator are independently separated. A refrigerant circuit characterized by being connected to each other by suction pipes. 2. The refrigerant circuit according to claim 1 of the utility model registration claim, wherein each compression element has a different displacement volume. 3. The refrigerant circuit as set forth in claim 1 of the utility model registration claim, wherein each compression element is provided with an independent power saving mechanism. 4. The refrigerant circuit described in item 1 of the utility model registration claim, characterized in that an on-off valve is provided on the inlet side of each pressure reducing device. 5. Request for registration of a utility model characterized in that a power save mechanism provided independently on each compression element and an on-off valve provided independently on the inlet side of each pressure reducing device are controlled by a control device. The refrigerant circuit described in item 3 or 4 of the range.
