Abstract

PURPOSE:To provide the most suitable controlling operation for a refrigerator by a method wherein a surrounding temperature and humidity of a room used are monitored, compared with a target temperature and humidity of the room, a correction value is a determined in response to a difference between the actual value and the target value so as to calculate a target outlet temperature, the target outlet temperature is compared with an outlet temperature to control the refrigerator. CONSTITUTION:A difference between a designed inlet temperature of a refrigerator and its designed outlet temperature is calculated at a refrigerator outlet temperature adjustment device 10, its difference is defined as alpha, a room temperature where a cooling load in the room shows a maximum value is calculated and then a difference between the room temperature and the room target temperature is defined as DELTAt. A present room temperature is measured by a temperature sensor 8 and a difference between the measured value and the room target temperature is difened as DELTAt'. A corrected value (alpha') of a target refrigerator outlet water temperature is calculated with reference to a relation of DELTAt'.alpha/DELTAt=alpha' and the corrected value alpha' is subtracted from the retrigerator designed inlet temperature, thereby a new target refrigerator outlet temperature can be attained. The target refrigerator outlet temperature is compared with an outlet water temperature measured by a refrigeratore outlet water temperature sensor 6. If the measured value is lower than the refrigerator outlet target water temperature, a refrigerator off instruction is outputted. With this instruction, a refrigerator adjustor 11 performs an on and off control of the refrigerator.
