Abstract

This refrigeration cycle device is provided with: a refrigerant circuit in which a compressor, a condenser, an expansion valve, and an evaporator are connected in the stated order by refrigerant piping; and an expansion valve control unit that adjusts the opening degree of the expansion valve. The expansion valve control unit is configured so as to: store a first table in which there is defined a freezing performance in which the range of performance of the evaporator is quantified, as well as a relationship between the expansion valve opening degree and a plurality of types of refrigerant; and determine, on the basis of the first table, an optimal usage range from an upper limit to a lower limit of the expansion valve opening degree that correspond to the refrigerant used.
