The invention belongs to the technical field of air conditioners, and specifically provides a method for controlling the opening of an electronic expansion valve of an air conditioner. The invention aims to solve the problem of poor overall performance of the air conditioner caused by inflexible control of the opening of the electronic expansion valve in the initial operation stage of the existing air conditioner. The control method for the opening degree of the electronic expansion valve of the air conditioner of the present invention comprises the following steps: determining the target opening degree of the electronic expansion valve; making the opening degree of the electronic expansion valve reach the target opening degree in a staged manner; wherein, the target opening degree is The opening degree of the electronic expansion valve after the air conditioner starts the preset running time. This setting improves the heating / cooling speed of the air conditioner at the initial stage of start-up operation, improves the overall performance of the air conditioner at the initial stage of start-up operation, and achieves precise control of the opening of the electronic expansion valve through a staged control method to ensure The exhalation temperature of the compressor can reach the target exhalation temperature stably, thereby improving the experience of using the air conditioner.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a method for controlling the opening of an electronic expansion valve of an air conditioner. Background technique [0002] The air conditioner is equipped with an electronic expansion valve. In the initial stage of starting the air conditioner (for example, a few minutes before the air conditioner is started), a fixed initial opening is usually set for the electronic expansion valve to control the electronic expansion valve to operate according to this fixed initial opening. , and then determine the action of the electronic expansion valve according to the comparison between the data received by the sensor and the preset parameters, and the air conditioner can enter a stable operation stage at this time. In order to ensure the operation stability of the air conditioner, the initial opening degree set by the current control method is usually set to an opening deg...
