PROBLEM TO BE SOLVED: To prevent even operational stopping of a device by a malfunction by preventing reduction in refrigeration capacity by stabilizing a flow of a refrigerant in a refrigerant circuit even at low outside air temperature when performing heating operation of the 100% heat recovery without using an outdoor heat exchanger in a refrigeration device having a use side heat exchanger of a plurality of systems and a consolidating liquid side connection piping into a single line by liquid lines of a plurality of systems. SOLUTION: This refrigeration device connects a liquid refrigerant flow passage 66 to a hear source side liquid pipe 62 of san outdoor unit 10 and an inflow port of a receiver 17 connected to a liquid gathering pipe 53 of the liquid side connection piping 53, 54 and 55, and an opening-closing valve SV1 capable of controlling opening and closing is arranged in this liquid refrigerant inflow passage 66.
