Abstract

The present invention provides an air conditioning system and a control method thereof, including an outdoor heat exchanger, the outdoor heat exchanger includes at least two heat exchange sections, at least one of the heat exchange sections has a direct or indirect connection with the indoor heat exchanger The heat exchange state and the defrosting state that are directly or indirectly connected to the exhaust port of the indoor heat exchanger and the compressor at the same time. In the air-conditioning system and its control method provided by the present invention, the outdoor heat exchanger is divided into a plurality of heat exchange sections to realize zone defrosting, and a small amount of heat is used to concentrate one heat exchange section for defrosting, and the defrosting time is not only shortened but also used The heating energy loss is small, the heat utilization rate becomes higher, and the defrosting is more timely. The heating capacity of the entire heating cycle has also been improved, and user comfort has been better optimized.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to an air conditioning system and a control method thereof. Background technique [0002] At present, continuous heating of air conditioners has always been a research trend, and major manufacturers are constantly optimizing air conditioning systems to achieve the effect of continuous heating. The most common way is to use the heat storage module as the condenser to store heat first, and then act as the evaporator to release heat when defrosting. However, this method needs to add more equipment and more pipelines, and the cost is high; and the energy provided by the heat storage module is limited, which will affect the defrosting effect, and even if continuous heating is realized, the indoor comfort will be greatly reduced. Contents of the invention [0003] In order to solve the technical problem in the prior art that the comfort of the air-conditioning system de...
