Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0039] See figure 1 , which is a flowchart of an embodiment of the method for determining the initial opening degree of the electronic expansion valve of the air conditioner based on the present invention.
[0040] Such as figure 1 As shown, this embodiment uses the following process to determine the initial opening of the electronic expansion valve of the air conditioner:
[0041] Step 11: Obtain the current rated frequency and current rated capacity parameters of the current air conditioner.
[0042] The current air conditioner refers to an air conditioner that is running and needs to determine the initial opening degree of the electronic expansion valve. Both the current rated frequency and the current rated capacity parameters refer to the c...

The invention discloses a method and device for determining the initial opening degree of an air conditioner electronic expansion valve. The method includes: obtaining the current rated frequency and current rated capacity parameters of the current air conditioner; searching for a benchmark consistent with the current rated capacity parameters Rated capacity parameters, obtaining the number of reference data records containing the reference rated capacity parameters; calculating the ratio of the current rated frequency to the reference rated frequency; adjusting the reference initial opening parameters according to the ratio to obtain the current initial An opening parameter: determine the current initial opening of the electronic expansion valve of the air conditioner according to the current initial opening parameter. The application of the present invention can solve the problems in the prior art that the initial opening of the electronic expansion valve is determined unreasonably based on experience or that all air conditioners are determined by the test method, which leads to complicated process and difficult realization.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, specifically relates to the control of an air conditioner, and more specifically relates to a method and a device for determining the initial opening degree of an electronic expansion valve in an air conditioner. Background technique [0002] The electronic expansion valve is used in the refrigerant circulation system of the air conditioner. By adjusting the opening of the electronic expansion valve, the refrigerant circulation volume in the system can be adjusted to meet the performance requirements of the air conditioner. Generally, when the air conditioner is just started, the electronic expansion valve operates at the initial opening degree, and then adjusts the electronic expansion valve opening degree according to the set control strategy after reaching the set condition. [0003] In the electronic expansion valve control method, the selection of the initial opening is extremely im...
