Abstract

The invention discloses a control method and a device for an initial openness of an electronic expansion valve and an air conditioning system. The method comprises the steps of: obtaining a present outdoor temperature; calculating a proportional parameter corresponding to the present outdoor temperature based on preset calculation rules; calculating a target operation frequency of an air conditioning set; calculating a product between the proportional parameter and the target operation frequency of the air conditioning set to obtain an initial openness numerical value of the electronic expansion valve; and controlling the electronic expansion valve to operate according to the initial openness numerical value. The method can enable the electronic expansion valve to work according to the proper initial openness so as to help the air conditioning system to quickly enter a stable state; and compared with the prior art, a certain energy saving effect is achieved in the operation process.

Description

technical field

[0001] The invention relates to the field of control technology, in particular to a control method, device and air conditioning system for the initial opening of an electronic expansion valve. Background technique

[0002] In today's economic society, air conditioners are widely used because of their good cooling and heating effects.

[0003] The initial opening of the electronic expansion valve refers to the preset value of the electronic expansion valve when the air conditioning system is just started. The initial opening of the electronic expansion valve plays a vital role in the stability of the air conditioning system. If the initial opening of the electronic expansion valve is not selected properly, the air conditioning system will stabilize very slowly. If the initial opening of the electronic expansion valve is selected properly, the air conditioning system will be very slow. Stabilization can be reached sooner, and the air conditioning system will o...
