Abstract

The invention discloses a deforesting method of a multi-split air conditioner. The multi-split air conditioner is provided with an air supply electronic expansion valve, an economizer and a throttlingassembly, wherein an inlet of the air supply electronic expansion valve is connected with an auxiliary road outlet of the throttling assembly, an outlet of the air supply electronic expansion valve is connected with an auxiliary inlet of the economizer, the defrosting method of the multi-split air conditioner includes the following steps: after the multi-split air conditioner enters into a heating mode, whether the multi-split air conditioner meets defrosting condition or not is judged; when the multi-split conditioner meets the defrosting condition, an outdoor unit is controlled to switch tothe heating mode, and the air supply electronic expansion valve is controlled to open as first preset opening. The invention further discloses the multi-split air conditioner. According to the multi-split air conditioner and the defrosting method thereof, deforesting time of the multi-split air conditioner is shortened.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a multi-connected air conditioner and a defrosting method thereof. Background technique [0002] Due to its high efficiency, energy saving, free combination layout, and huge application engineering, the multi-line is more and more popular in the market. With the gradual increase of the multi-line market, customers' demand for large-capacity single multi-line is also increasing. [0003] As the market's requirements for multi-split units are getting higher and higher, the length of the refrigerant pipes in the project is also getting longer and longer. Midea Multi-line claims that the longest single pipe length of the system can reach 220m, and Haier Multi-line’s maximum total piping length is 1100m. [0004] The larger the air conditioning system, the longer the refrigerant cycle, and the greater the energy loss in the pipeline. Considering the requirements of comfort...
