Abstract (en)
[origin: EP3264008A1] A controller of a refrigeration apparatus includes a temperature determination unit configured to determine whether a heat radiating unit temperature is within a target temperature range, a superheat degree calculation unit configured to calculate a degree of superheat of refrigerant flowing through an economizer from a state of refrigerant detected in a state detection unit, and an opening degree control unit configured, when the temperature determination unit determines that the heat radiating unit temperature is within the target temperature range, to control an opening degree of a flow rate regulation device so that the degree of superheat calculated in the superheat degree calculation unit reaches a target degree of superheat, and configured, when the temperature determination unit determines that the heat radiating unit temperature is outside the target temperature range, to control an opening degree of the flow rate regulation device so that the heat radiating unit temperature falls within the target temperature range.
