1. A compressor unit comprising:
a first case;
a compressor accommodated in the first case;
a connecting port including a first liquid connecting port, a first gas connecting port, a second liquid connecting port, and a second gas connecting port;
a shutoff valve including a first liquid shutoff valve, a first gas shutoff value, a second liquid shutoff value and a second gas shutoff valve;
a leakage detection sensor accommodated in the first case and configured to detect leakage of the refrigerant; and
a controller configured to close the first liquid shut off value, the first gas shutoff valve, the second liquid shutoff valve, and the second gas shutoff valve, when the leakage detection sensor detects leakage of the refrigerant,
wherein
the compressor, a heat source heat exchanger, and a utilization heat exchanger constitute a refrigerant cycle adopting the heat source heat exchanger as a heat source and configured to cause circulation of a refrigerant,
the heat source heat exchanger is accommodated in a second case provided separately from the first case,
the utilization heat exchanger is accommodated in a third case provided separately from the first case,
the compressor unit is disposed inside a building,
the first connecting port is connected to the heat source heat exchanger via a first connection piping,
the second connecting port is connected to the utilization heat exchanger via a second connection piping,
the controller is configured to shut the first liquid shutoff valve and the first gas shutoff valve so that the first liquid shutoff valve and the first gas shutoff valve shut off flow of the refrigerant between the first connecting port and the heat source heat exchanger, and
the controller is configured to shut the second liquid shutoff valve and the second gas shutoff valve so that the second liquid shutoff valve and the second gas shutoff valve shut off flow of the refrigerant between the second connecting port and the utilization heat exchanger.
