Abstract

The invention relates to an electronic expansion valve opening degree correction method for unit, a control equipment and an air conditioning system. The method for correcting the opening degree of the unit electronic expansion valve comprises the following steps of acquiring the current working parameters of the unit; confirming the current target opening degree value according to the current working parameters; resetting the electronic expansion valve when the opening degree of the electronic expansion valve of the unit is not accurate according to the current working parameters; adjusting the opening degree of the reset electronic expansion valve according to the current target opening value. According to the electronic expansion valve opening degree correction method for unit, the control equipment and the air conditioning system, the accuracy of the opening degree of the electronic expansion valve can be improved, so that the operation reliability of the unit is improved.

Description

technical field [0001] The present application relates to the technical field of electrical equipment, in particular to a method for correcting the opening of an electronic expansion valve of a unit, a control device and an air-conditioning system. Background technique [0002] Electronic expansion valves are commonly used in air-conditioning units, refrigeration units, etc. Install the electronic expansion valve on the pipeline of the unit, and adjust the opening of the electronic expansion valve by sending commands to the electronic expansion valve, so as to control and adjust the liquid supply through the pipeline. The amount of liquid supplied affects the reliability of operation, so whether the opening of the electronic expansion valve is accurate will affect the reliability of the overall unit operation. [0003] In traditional units, the reset action of the electronic expansion valve is generally performed once at startup to ensure that the actual number of steps of ...
