Title:
HEAT EXCHANGER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/143540
Kind Code:
A1
Abstract:
A heat exchanger and an air conditioner, the heat exchanger comprising a heat exchange pipe group (1), a supercooling pipe group (2), a supercooling bypass pipe (3), a first one-way valve (4), a second one-way valve (5) and a third one-way valve (6), wherein a first end of the supercooling bypass pipe (3) is connected to a parallel branch between a first diverter (7) and the supercooling pipe group (2), and a second end is connected to a pipe section at one side of a second diverter (8) of a main pipeline; the first one-way valve (4) is provided on the supercooling bypass pipe (3); the second one-way valve (5) is provided on a pipe section between the first diverter (7) of the parallel branch and the first end of the supercooling bypass pipe (3); and the third one-way valve (6) is provided on a pipe section between the second diverter (8) of the main pipeline and the second end of the supercooling bypass pipe (3). The advantageous effect of the present invention is that when the heat exchanger performs a heating operation, the one-way valves are used to divide the heat exchanger, which may reduce the degree of complexity of the system and reduce system pressure loss caused by the supercooling pipe group during heating, thereby improving the heat exchange efficiency of the system.
