Title:
ガスエンジン駆動式空気調和装置
Document Type and Number:
Japanese Patent JP7065552
Kind Code:
B2
Abstract:
To provide gas engine driven air conditioning equipment that comprises one or a plurality of outdoor units and a plurality of indoor units, keeps a cooling room and a heating room comfortable and furthermore allows for reduction of load on a compressor compressing refrigerant.SOLUTION: A control device CT controls the openings of a plurality of valves and the number of revolutions of a gas engine 12 so that the physical quantity related to a refrigerant on the suction port side of a compressor 11 matches a predetermined target value and the physical quantity related to the refrigerant on the delivery port side of the compressor 11 matches a predetermined target value. The control device CT corrects the target value of the low-pressure side physical quantity, and controls the heat transfer amount per unit time to the refrigerant by a waste heat recovery heat exchanger on the basis of one or more values selected from a current value of the low-pressure side physical quantity, the corrected target value of the low-pressure side physical quantity, a current value of the high-pressure side physical quantity and the target value of the high-pressure side physical quantity when operating at least one indoor unit among the indoor units 20A, 20B, ... as a cooling device and operating at least one indoor unit as heating device.SELECTED DRAWING: Figure 4
