Embodiment Construction
[0019] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the present application is described in conjunction with an air conditioner, the technical solution of the present invention is not limited thereto, and the electronic expansion valve control method can obviously also be applied to other similar occasions such as heat pump water heaters and heat pump clothes dryers. Such changes do not depart from the principle and scope of the present invention.
[0020] It should be noted that, in the description of the present invention, terms such as "upper", "inner", "outer" and other indicated directions or positional relationships are based on the directions or positional relationshi...

The invention relates to the technical field of air conditioners, and specifically provides an electronic expansion valve control method for air conditioners and an air conditioner, aiming to solve the problem of poor reliability of the existing air conditioner electronic expansion valves. For this purpose, the electronic expansion valve control method includes the following steps: obtaining the stop time of the compressor; judging whether to execute the reset operation of the electronic expansion valve according to the stop time. The air conditioner includes a compressor and a control mechanism, and the control mechanism is used to implement the above electronic expansion valve control method. The present invention judges whether to perform the reset operation of the electronic expansion valve according to the downtime of the compressor, avoids performing the reset operation every time the compressor is started, reduces the number of reset operations, and thus avoids the gear inside the electronic expansion valve Or other components form excessive fit, which improves the reliability of the electronic expansion valve, prolongs the service life of the electronic expansion valve, and thus improves the user experience.
Description
technical field [0001] The invention relates to the technical field of expansion valves, and specifically provides an electronic expansion valve control method for an air conditioner and an air conditioner. Background technique [0002] Air conditioning refers to the process of regulating and controlling the ambient air in a building or structure by artificial means. During the operation of the air conditioner, the electronic expansion valve is used to control the flow of the refrigerant pipeline to adjust the indoor temperature, so as to meet the user's comfort requirements. However, due to the difference between the preset step threshold and the actual step number of the electronic expansion valve, for example, the preset step threshold is 500 steps, and the actual step number is 510 or 490 steps. With the repeated adjustment of the electronic expansion valve, the accumulated The step deviation is getting bigger and bigger, which will lead to out-of-step phenomenon, which...
