Abrégé
The purpose of the present invention is to provide a system and method with which it is possible to minimize a temperature decrease during a dehumidification operation by each indoor unit, and in which the dehumidification capability does not decrease during low load. In an air-conditioning system: an indoor unit includes an indoor heat exchanger, a temperature detection means for detecting the indoor temperature, and a humidity detection means for detecting the indoor humidity; and an outdoor unit includes an outdoor heat exchanger and a compressor for circulating a refrigerant between the outdoor unit and the indoor unit. The air-conditioning system is provided with: a valve provided between the outdoor heat exchanger and the indoor heat exchanger; a rotation speed control means 32 for controlling the rotation speed of the compressor according to the temperature detected by the temperature detection means; and an opening degree control means 33 for controlling the opening degree of the valve according to the humidity detected by the humidity detection means.Classes IPC ?
