Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/065924
Kind Code:
A1
Abstract:
This air conditioning device is provided with: a heat medium circulation circuit (B) in which a pump (22) for delivering a heat medium which contains water or brine and which serves as a medium for transporting heat, a plurality of indoor heat exchangers (31a-31c) for exchanging heat between the heat medium and indoor air to be air conditioned, and a flow rate regulation device for regulating the flow rate of the heat medium flowing through the indoor heat exchangers, are connected by piping, and through which the heat medium is circulated; and a heat source-side device (A) for heating or cooling the heat medium to be sent to the indoor heat exchangers. The air conditioning device is further provided with voltage lowering equipment (23) which, on the basis of the magnitude of an electric current supplied to the pump so as to correspond to the flow rate of the heat medium flowing through the heat medium circulation circuit, lowers a voltage applied to the pump.
