Abstract

The invention discloses a method for preventing an electronic expansion valve from getting stuck. The method includes the steps that after an air conditioner is started, whether the electronic expansion valve of the air conditioner is reset or not is judged; when the electronic expansion valve of the air conditioner is not reset, the electronic expansion valve is controlled to rotate reversely by a first preset step number for zero setting; and after zero setting of the electronic expansion valve, the electronic expansion valve is controlled to rotate forwards to the initial opening degree for operation, and resetting operation of the electronic expansion valve is completed. The invention further discloses a device for preventing the electronic expansion valve from getting stuck. By means of the method and device, the probability that the electronic expansion valve gets stuck is lowered, quality complaints are reduced, and the product experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method and device for preventing electronic expansion valves from being stuck. Background technique [0002] With the progress of society, more and more electronic expansion valves are used to realize throttling, so as to improve the comfort of use. The electronic expansion valve is a precision component, and its service life and reliability requirements are relatively high. However, the quality of electronic expansion valves varies from good to bad, and some brands and samples of substandard quality are prone to stuck problems during actual use. Especially in the occasions where the computer room is used or the home users in developed countries, after the air conditioner is turned on, it generally does not stop, and it is used all the year round. During this process, the electronic expansion valve is constantly adjusted, especially the frequent reset action of the va...
