摘要： In a refrigerating air conditioning system using refrigerant such as CO2 used in a supercritical area, a highly efficient refrigerating air conditioning system is provided by adjusting the amount of refrigerant in a radiator which contributes to the efficiency of the system stably and quickly. During heat utilizing operation, the superheat at the exit of an evaporator is controlled to a predetermined value by controlling the opening of an expansion valve provided on the upstream side of the evaporator, and an expansion valve is controlled so that the state of refrigerant in a connection pipe on the high-pressure side becomes a supercritical state. In this state, a flow rate control valve is controlled to change the density of the refrigerant stored in a refrigerant storage container and the amount of refrigerant existing in the radiator is adjusted. A target high-pressure value and a target value of the radiator exit temperature are set and the capacity of the compressor is controlled to obtain the target values, and the amount of refrigerant existing in the radiator is adjusted by the refrigerant amount adjusting circuit.

The apparatus further includes a control unit having a memory, and is configured to calculate an internal volume of the extension pipe and calculate a standard refrigerant amount, serving as a criterion for determining whether the refrigerant is leaked from the refrigerant circuit, on the basis of the calculated refrigerant extension pipe internal volume. The memory is configured to store the refrigerant extension pipe internal volume and the standard refrigerant amount. The control unit is configured to calculate a total amount of refrigerant in the refrigerant circuit on the basis of the refrigerant extension pipe internal volume stored in the memory and operation data measured during normal operation, and compare the calculated total refrigerant amount with the standard refrigerant amount stored in the memory to determine whether refrigerant is leaked.
