摘要： PROBLEM TO BE SOLVED: To solve a problem in which it is difficult to control the operation of a refrigerating device to accurately grasp the condition of the refrigerating device and to efficiently output a necessary refrigerating capacity by a conventional control method (zone control and the like) controlling the operations of compressors by comparing a measured value or a calculated value obtained from the measured value and a threshold, with respect to a method of deciding operational frequencies of the compressors and the number of operated compressors in the refrigerating device comprising the invertor compressor and the constant-velocity compressor. SOLUTION: The operational frequencies of the compressors and the number of operated compressors are calculated to output the refrigerating capacity necessary for the refrigerating device on the basis of low pressure, a rate of change of the low pressure, deviation of the low pressure from a target low pressure, the present operational frequencies of the compressors, and the number of operated compressors. The condition of the refrigerating device can be grasped in detail by considering the rate of change of the low pressure. Further the target low pressure can be accurately obtained by considering the deviation of the low pressure from the target low pressure. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that in a refrigerant circuit having a compressor, a condenser, a decompression device, and an evaporator annularly connected by piping in an air conditioner for air-conditioning a low temperature show case installed in a store such as a convenience store or for air-conditioning a store, the COP (Coefficient of Performance) is better when the high pressure side pressure of the compressor is low, but because the condensation pressure when the outside air temperature is low becomes remarkably low and the pressure difference between the high pressure side and the low pressure side becomes small, a refrigerant does not flow even when an expansion valve operates. SOLUTION: In the refrigerating cycle device having the refrigerant circuit, when the outside temperature is low, the number of operating compressors and/or condensation capacity of the condenser is controlled so that the pressure difference between the low pressure side pressure and the high pressure side pressure of the compressor is a set value or within a set range.
