AIR CONDITIONER

摘要

To obtain an air-conditioning apparatus that makes no refrigerant circulate into an indoor unit and can achieve energy-saving. A refrigeration cycle is configured by connecting a compressor 10 that compresses the refrigerant, a four-way valve 11 that switches the circulation path of the refrigerant, a heat source side heat exchanger 12 that exchanges heat, expansion valves 16a to 16d that adjust the pressure of the refrigerant, and two or more intermediate heat exchangers 15a and 15b that exchange heat between the refrigerant and the heat medium to heat and cool the heat medium, by piping. A heat medium circulation circuit is configured by connecting two or more intermediate heat exchangers 15a and 15b, pumps 21a and 21b that pressurize the heat medium, two or more use side heat exchangers 26a to 26d that exchange heat between the heat medium and the air in the indoor space 7, and flow path switching valves 22a to 22d and 23a to 23d that switch pass of the heated heat medium or the cooled heat medium to the use side heat exchangers 26a to 26d, by piping.
