Beschreibung
Zusammenfassung:	An operation control device in a refrigerating and air-conditioning apparatus includes a correction amount setting unit configured to reduce, by a predetermined change amount at each setting, a temperature correction amount for such a correction that a necessary air-conditioning capability is lower than an air-conditioning capability corresponding to a set temperature, a target suction temperature setting unit configured to set a target suction temperature based on the temperature correction amount set by the correction amount setting unit and the set temperature, a target refrigerant temperature setting unit configured to set a target refrigerant temperature of refrigerant flowing into a use side heat exchanger so that a suction temperature is equal to the target suction temperature, and a compressor control unit configured to control a capacity of a compressor so that the refrigerant flowing into the use side heat exchanger has the target refrigerant temperature.
