Abstract:
1. 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; in the case of providing with two-position three-way electromagnetic valve, one end of the electromagnetic valve the direction 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 three-way electromagnetic valve ( 4 ) being connected with said two groups of capillary tubes ( 5 , 6 ) respectively.
