PROBLEM TO BE SOLVED: To provide a refrigeration air conditioning device which performs determination of whether or not concentration of a refrigeration is at risk of reaching limit concentration in an air-conditioned space, when the refrigerant leaks during construction, and based on the determination result, which secures safety with respect to leakage of the refrigerant surely, in the refrigeration air conditioning device having a refrigerant circuit in which the refrigerant circulates and a control device which performs operation control of devices constituting the refrigerant circuit.SOLUTION: A refrigeration air conditioning device includes: a refrigerant circuit in which a refrigerant circulates; and a control device for performing operation control of devices constituting the refrigerant circuit. Then, an operation including a test operation of the refrigerant circuit can be performed only after a construction time determination result of whether or not exceeding a safety measure threshold value in which a safety measure with respect to the leakage of the refrigerant is needed to be administered has been inputted in the control device, or only after construction time determination information necessary for acquiring the construction time determination result is inputted in the control device and the construction time determination result has been acquired.SELECTED DRAWING: Figure 4 |
