PURPOSE:To perform accurate control at any time, by regulating a variable capacity system for compressor on the basis of the difference between the target delivery pressure to be operated on the basis of engine operating state and the actual delivery pressure. CONSTITUTION:It is provided with first means 66 for detecting at least one data selected from engine load, rotation, compressor temperature, thermal load of evaporator 6, rotation of fan 5, etc. as an electric signal to operate the target delivery pressure of compressor 20 on the basis of detected data by means of an arythmetic means 100. While second means 67 for detecting the actual delivery pressure of compressor 20 is provided to operate the difference between the actual delivery pressure and target deliver pressure by means of an arithmetic means 200. Thereafter, correction of capacity of compressor 20 is operated by an arithmetic means 300 to control a variable capacity system 33 by means of control means 400 on the basis of the operational results. |
