Title:
空気調和装置
Document Type and Number:
Japanese Patent JP5328933
Kind Code:
B2
Abstract:
The present invention obtains an air-conditioning apparatus capable of improving energy efficiency and achieving energy savings by adjusting a flow rate of a refrigerant and a heat medium involved in heat exchange. The air-conditioning apparatus includes a refrigerant circuit A having a plurality of expansion devices 16 that controls a flow rate of the refrigerant flowing in each of a plurality of heat exchangers related to heat medium 15; a heat medium circuit B having the heat exchangers related to heat medium 15 and a use side heat exchanger 26 that exchanges heat between the heat medium and air; a first heat medium flow switching device 22 and a second heat medium flow switching device 23 disposed on an inflow side and an outflow side of the heat medium of the use side heat exchanger 26 in which the flow switching devices mixes or diverges the heat medium pertaining to the heat exchangers related to heat medium 15 by control of the opening degrees; and a controller that controls the opening degree of at least the heat medium flow switching device on the inflow side or the outflow side in which the heat medium flow switching device controls the amount of heat exchange in each of the heat exchangers related to heat medium during cooling only operation mode or heating only operation mode.
