The invention relates to a novel structured air-conditioner with both cooling and warming functions, comprising a compressor, an out-door heat exchanger, an in-door heat exchanger and a four-way change-over valve, characterized in that it further comprises a parallel capillary device, a parallel expansion valve device or a combination of parallel capillary and expanding valve connected with the in-door and the out-door heat exchanger respectively. Said parallel capillary device, said parallel expansion valve device or the combination comprises a two-position three-way change-over valve or one-way valve with opposite direction of leading through and two groups of parallel capillary tube, two groups of parallel expanding valve, parallel capillary tube and expanding valve or a combination of two groups of series capillary tube and expansion valve. The invention provides a new generation of air-conditioner with both cooling and warming functions having novel structure, excellent performance, low energy consume and high efficiency.
An air-conditioner with both cooling and warming functions, comprising a compressor (1), an out-door heat exchanger (3), an in-door heat exchanger (7), a four-way change-over valve (2) and a parallel capillary device (13), wherein the parallel capillary device (13) is connected with the in-door and the out-door heat exchanger (7, 3), characterized in that said parallel capillary device (13) comprises a combination of a two-position three-way electromagnetic valve (4) or two one-way valves (9, 10) with opposite direction of leading through and two group of parallel capillary tubes (5, 6), in the case of providing with two one-way valves (9, 10) with opposite direction of leading through, one end of one-way valves (9, 10) being directly connected with said out-door heat exchanger (3) respectively, while the other ends of said one-way valve (9, 10) being connected with said two group of parallel capillary tubes (5, 6) respectively;
An air-conditioner with both cooling and warming functions, comprising a compressor (1), an out-door heat exchanger (3), an in-door heat exchanger (7), a four-way change-over valve (2) and a parallel expanding valve device (14), wherein the parallel expanding valve device (14) is connected with the in-door and the out-door heat exchanger (7, 3), characterized in that said parallel valve expanding device (14) comprises a combination of a two-position three-way electromagnetic valve (4) or two one-way valves (9, 10) with opposite leading direction and two groups of parallel expansion valve devices (11,12), in the case of providing with two one-way valves (9, 10) with opposite leading direction, one end of one-way valves (9, 10) being connected directly with said out-door heat exchanger (3) respectively, while the other ends of the one-way valves (9, 10) being connected respectively with said two groups of parallel expansion valves (11, 12), in the case of providing with two-position three-way electromagnetic valve (4), one end of the two-position three-way electromagnetic valve, of which the direction of inlet and outlet could be changed, being connected with the out-door heat exchanger (3) directly, while the other two ends of the three-way electromagnetic valve (4) being connected respectively with two groups of parallel expansion valves (11, 12).
An air-conditioner with both cooling and warming functions, comprising a compressor (1), an out-door heat exchanger (3), an in-door heat exchanger (7), a four-way change-over valve (2) and a combination (15) of parallel capillary tube and expansion valve, wherein the combination (15) of parallel capillary tube and expanding valve is connected with in-door and out-door heat exchanger (7, 3), characterized in that said device combination (15) of parallel capillary tube and expansion valve comprises a two-position three-way electromagnetic valve (4) or two one-way valves (9, 10) with opposite leading direction and the combination of a group of parallel capillary tube and a group of expanding valve, in the case of providing with two one-way valves (9, 10) with opposite leading direction, one end of one-way valves (9, 10) being connected directly with said out-door heat exchanger (3) respectively, while the other ends of the one-way valves (9, 10) being connected with a group of parallel capillary tube (5) and a group of expanding valve (12) respectively, in the case of providing with two-position three-way electromagnetic valve (4), one end of two-position three-way electromagnetic valve (4), of which the direction of inlet and outlet could be changed being connected with said out-door heat exchanger (3) directly, while the other two ends of the three-way electromagnetic valve (4) being connected with a group of parallel capillary tube (5) and a group of expansion valve (12) respectively.
