Abstract

The invention discloses an air conditioning system which comprises an indoor heat exchanger, a switching module and at least two outdoor heat exchanger branches. Each outdoor heat exchanger branch comprises an outdoor heat exchanger and a first throttling device which are connected in series, wherein the first throttling device is connected with the indoor heat exchanger. The switching module comprises first reversing valves, wherein the first reversing valves are in one-to-one correspondence with the outdoor heat exchanger branches, and the connection mode between the outdoor heat exchanger branches and the indoor heat exchanger is switched between the series connection mode and the parallel connection mode through the first reversing valves. According to the air conditioning system, the defrosting effect is improved on the basis of heat supplying during defrosting, meanwhile, a pipeline structure of the whole air conditioning system is simple, and a control system of the whole air conditioning system is simplified.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, and more specifically, relates to an air conditioning system. Background technique [0002] When the air conditioning system is in the heating mode, the temperature of the outdoor heat exchanger is low, and the problem of frosting is more likely to occur. When the outdoor heat exchanger is frosted to a certain extent, the heat exchange efficiency will drop, and it is necessary to defrost at this time. [0003] At present, the commonly used defrosting method is: switch the air conditioner to cooling mode and defrost the outdoor heat exchanger. Heating, the indoor temperature decreases accordingly, and the user's comfort level is poor. [0004] In order to improve user comfort and realize heat supply during defrosting, two outdoor heat exchangers are connected in series, and the two outdoor heat exchangers realize evaporator mode and condenser mode alternately through valves and ...
