摘要： This refrigerating device (90) has a refrigerant circuit (80) including a utilization unit (20). The utilization unit (20) has: a heat exchanger (22); a first refrigerant pipe (71) and a second refrigerant pipe (72) which are connected to the heat exchanger (22); and a first shutoff valve (51) and a second shutoff valve (52) which are respectively provided in the first refrigerant pipe (71) and the second refrigerant pipe (72) and each of which has an adjustable opening degree. The refrigerating device (90) is provided with a refrigerant leakage detecting unit (26), a refrigerant pressure acquisition unit (27), and a control unit (25) which adjusts the opening degrees of the first shutoff valve (51) and the second shutoff valve (52). In a caution required state, in which both the first shutoff valve (51) and the second shutoff valve (52) are closed and the refrigerant leakage detecting unit (26) detects a leak, the control unit (25) adjusts the opening degree of at least one among the first shutoff valve (51) and the second shutoff valve (52) toward the open direction when the pressure of a refrigerant is greater than a predetermined threshold value.

摘要： An air-conditioning device (10) is equipped with: a suction temperature sensor (61) that is provided within an indoor unit (12); a wireless temperature sensor unit (13) that is separate from the indoor unit (12); an abnormality determination unit (63b) that determines whether or not the wireless temperature sensor unit (13) is under abnormal conditions; an index setting unit (63c) that sets a temperature index value; and control units (28, 66) that control the operation of the air-conditioning device (10) on the basis of the set temperature index value. The index setting unit (63c) sets the measurement value (Tm1) of the suction temperature sensor (61) as a temperature index value while it is determined by the abnormality determination unit (63b) that the wireless temperature sensor unit (13) is under abnormal conditions.
