Abstract

The invention discloses an air conditioning system which includes a first branch pipe and a refrigerant circulation main loop formed by connecting a compressor, a four-way reversing valve, an indoor heat exchange device, an outdoor heat exchange device and a throttling component through a main pipe; one end of the first branch pipe is connected to the exhaust end of the compressor, one end of thefirst branch pipe is connected to the part, between the outdoor heat exchange device and the throttling component, of the main pipe, and a first control valve is installed on the first branch pipe. The air conditioning system provided by the embodiment optimizes the system structure, does not need to switch the four-way valve during defrosting, meanwhile, can ensure that an indoor unit continues to blow out hot air to meet the heating demand and improves the user comfort.

Description

technical field

[0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system. Background technique

[0002] In severe cold weather, the outdoor unit of the air conditioner starts to frost shortly after running, and more and more frost forms as the running time prolongs, resulting in poor heating effect of the air conditioner, and the air conditioner needs to enter the defrosting stage. No hot air will be blown into the room, and only after the defrosting is completed, the air conditioner will run the heating mode again, and then frost will form, and the cycle will continue after defrosting. Such frequent frosting and defrosting operations will cause the air conditioner to supply heat intermittently. It is difficult to reach the comfortable temperature required by the human body, the comfort is poor, and it cannot even operate below -20 degrees Celsius.

[0003] In the study of the prior art, the inventors of the presen...
