Abstract

PURPOSE:To prevent deteriorated machines from further deteriorating or electric power from being excessively consumed, by providing a detecting means for detecting the deterioration of the machines equipped and also providing an operating condition setting means for setting the operating conditions of these machines in accordance with the degree of deterioration detected by the detecting means. CONSTITUTION:In order to judge the deterioration of refrigerating machines and the like in view of the efficiency thereof, a main control unit MCU 1 calculates efficiency on the basis of the data of the operating hours of respective machines 10... and the amount of electric power consumed, which is obtained by detectors 11..., and a deterio rated state is judged by comparing the gradients of the efficiency thus calculated. Thereupon, operating conditions are set in accordance with the deteriorated state. For example, when three machines are used and if one of them is markedly deteriorat ed, a load is to be redistributed so as to lighten the load applied on the said machine, and the lightened load will be shared by the other machines. Further, when two of them are markedly deteriorated, the remaining one machine is to be functioned as a base machine. Furthermore, if all of them are in the same state, the operating conditions are not to be altered. Thus, the MCU 1 sets the operating conditions in accordance with the deteriorated state.
