Patent ID: 10866004

Abstract:
A refrigeration apparatus includes a refrigerant circuit including a utilization unit. The utilization unit includes: a heat exchanger; first and second refrigerant pipes connected to the heat exchanger; and first and second shutoff valves each of whose opening degrees are adjustable and which are respectively provided at the first refrigerant pipe and the second refrigerant pipe. The refrigeration apparatus includes: a refrigerant leakage detector; a refrigerant pressure acquiring part; and a controller configured to adjust the opening degrees of the first shutoff valve and the second shutoff valve. In an alert state where the first shutoff valve and the second shutoff valve are both closed and the refrigerant leakage detector detects the leakage, the controller adjusts the opening degree of at least one of the first and second shutoff valves to open when the pressure of the refrigerant is greater than a predetermined threshold value.
