Title:
AIR-CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JP2022181304
Kind Code:
A
Abstract:
To provide an air-conditioning system that stabilizes temperatures of heat media flowing out of heat source apparatuses.SOLUTION: An air-conditioning system has a load apparatus, a plurality of heat source apparatuses, a differential pressure gauge, and an integrated control device. Each heat source apparatus is provided internally or externally with a flow rate acquisition device which acquires flow rate information on heat media, and comprises a heat medium heat exchanger, a compressor and a pump, and the integrated control device is configured to control the plurality of heat source apparatuses, and comprises an integrated communication part, a target flow rate determination part, a pump frequency calculation part, and a heat source indication part. The integrated communication part receives flow rate information from the flow rate acquisition device. The flow rate determination part determines a target flow rate of a heat medium based upon the differential pressure information that the differential pressure gauge acquires so that predetermined conditions are met. The pump frequency calculation part calculates, based upon the flow rate information, a pump frequency so that the flow rate of the heat media reaches the target flow rate. The heat source indication part controls the integrated communication part which transmits heat source indication information to the heat source apparatus so that the pump is operated at the calculated pump frequency.SELECTED DRAWING: Figure 6
