摘要： A supercooling heat exchanger of an air conditioning apparatus is configured to exchange heat between a high-pressure refrigerant and a low-pressure refrigerant. The supercooling heat exchanger is divided into first and second heat exchangers. One of the first and second heat exchangers is disposed so that the high-pressure refrigerant and the low-pressure refrigerant flow countercurrent to each other. The other of the first and second heat exchangers is disposed so that the high-pressure refrigerant and the low-pressure refrigerant flow parallel to each other. Preferably, both heat exchangers have a high-pressure liquid refrigerant pipe that is wound around the external periphery of a low-pressure refrigerant suction pipe. The heat exchangers are thereby reduced in size.

摘要： A movable valve element is provided so as to rotate about a predetermined shaft center. A first valve seat and a second valve seat are respectively arranged apart from the movable valve element with predetermined clearances on both sides of the movable valve element in a direction along the shaft center. A first sealing member is arranged around a communication path so as to seal a space inside the communication path from a space defined by the clearance on a side close to the first valve seat. A second sealing member is arranged around the communication path so as to seal the space inside the communication path from a space defined by the clearance on a side close to the second valve seat.

摘要： An air conditioning apparatus includes a supercooling heat exchanger configured to exchange heat between a high-pressure refrigerant and a low-pressure refrigerant. A high-pressure liquid refrigerant pipe is wound around an external periphery of a low-pressure refrigerant suction pipe. Preferably, the supercooling heat exchanger is disposed inside the indoor unit at a position below an evaporator. Drain water from the evaporator is dispersed over the supercooling heat exchanger or a drain pipe leading from a drain pan of the evaporator is wound together with the high-pressure liquid refrigerant pipe around the low-pressure refrigerant suction pipe. In either case, cold energy of the drain water effectively acts on the high-pressure liquid refrigerant pipe to exchange heat. The supercooling heat exchanger operates with improved efficiency without any increase in the volume of the heat exchanger so that the evaporator can be made as small and compact as possible.

摘要： An air conditioner that reverses and appropriately controls the stream of refrigerant between paths of a flow divider corresponding to an air conditioner heat exchanger having a plurality of paths to increase the heat exchange capacity is provided. The air conditioner includes a compressor, a four-way valve, an outdoor heat exchanger, a restriction device, and an indoor heat exchanger including a plurality of paths. These members are sequentially connected by a refrigerant pipe to form a refrigerant circuit. A flow divider including a plurality of paths is arranged between the indoor heat exchanger, which includes the plurality of paths, and the restriction device. A refrigerant flow amount regulation valve is provided for each of the plurality of paths in the flow divider. In a predetermined operation state, more refrigerant is distributed to a predetermined passage in which the processing capacity is large and the refrigerant temperature at an outlet of the indoor heat exchanger is high in comparison with other paths.
