    摘要： A first bypass pipe (6 )whose one end of the first bypass pipe (6) is connected to a main pipe (5) extending from a compressor (1) to an indoor heat exchanger (2), and whose the other end is branched off into parts that are each connected to the main pipe (5) on the inlet side of outdoor heat exchanger (4A, 4B) and a second bypass pipe (40) whose one end of the second bypass pipe (40) is connected to an injection port (43) communicating with the compression chamber of the compressor (1) in which compression is taking place and whose the other end is branched off into parts that are each connected to the main pipe (5) on the outlet side of the outdoor heat exchangers (4A, 4B) are provided. During a defrosting operation that removes frost on the outdoor heat exchangers (4A, 4B), a part of the refrigerant discharged from the compressor (1) is supplied from the first bypass pipe (6) to the outdoor heat exchanger to be defrosted, and is then passed through the second bypass pipe (40) and injected from the injection port (43) of the compressor (1).

    摘要： An air-conditioning apparatus 100 includes a heat source-side unit 1 including a compressor 10 that compresses a refrigerant and a heat source-side heat exchanger 12 that exchanges heat between air and the refrigerant, a plurality of use-side units 2a, 2b each including a use-side heat exchanger 26a that exchanges heat between air and a heat medium, and a plurality of intermediate heat exchangers 15a, 15b connected to the heat source-side unit 1 via a refrigerant pipe and to the use-side units 2a, 2b via a heat medium pipe, and configured to exchange heat between the refrigerant and the heat medium. Target determination means 521 detects condensation status of each of the use-side units 2a, 2b and determines whether to perform condensation suppression control for suppressing condensation with respect to each of the use-side units 2a, 2b according to the condensation status. The use-side unit 2b determined by the target determination means 521 to be subjected to the condensation suppression control is connected to an intermediate heat exchanger for adjustment 15b among the plurality of intermediate heat exchangers 15a, 15b. Refrigerant circuit control means 53c controls a temperature of the refrigerant flowing into the intermediate heat exchanger for adjustment 15b so that the heat medium temperature T of the heat medium flowing into at least one use-side unit the use-side units 2b enters a predetermined target set temperature range.

    摘要： A combined air-conditioning and hot water supply system includes a refrigerant circuit and a hot water supply-side control processing device 420. The refrigerant circuit is formed by connecting, by pipes, at least one heat source unit 110 including a compressor 111 and a heat source-side heat exchanger 113, at least one indoor unit 310 including an indoor-side heat exchanger 311 and an indoor-side expansion device 312, at least one hot water supply unit 410 including a refrigerant-water heat exchanger 411 and a hot water supply-side expansion device 412, and a branch unit 210 including a gas-liquid separator 211 and a solenoid valve 213. The gas-liquid separator 211 supplies a gaseous refrigerant to the indoor unit 310 and/or the hot water supply unit 410 which heats a target with which the gaseous refrigerant exchanges heat, and supplies a liquid refrigerant to the indoor unit 310 and/or the hot water supply unit 410 which heats a target with which the liquid refrigerant exchanges heat. The solenoid valve 213 controls the flow path of refrigerant in the indoor unit 310 and the hot water supply unit 410. The hot water supply-side control processing device 420 increases, while the hot water supply unit 410 is stopped, the pressure in a refrigerant-side flow path in the refrigerant-water heat exchanger 411 if the hot water supply-side control processing device 420 determines that there is a possibility of freezing of water in a water-side flow path in the refrigerant-water heat exchanger 411.
