Abstract

The invention discloses a method and device for determining the target exhaust temperature of an electronic expansion valve. The method includes: obtaining the current rated frequency and the current rated capacity parameters of the current air conditioner; Capability 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 target exhaust temperature parameter according to the ratio to obtain the current target Exhaust temperature parameter: determine the current target exhaust temperature of the electronic expansion valve of the air conditioner according to the current target exhaust temperature parameter. The application of the present invention can solve the problems in the prior art that the selection of the target exhaust temperature of the electronic expansion valve is unreasonable 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, in particular relates to the control of an air conditioner, and more specifically relates to a method and a device for determining the target exhaust temperature of an electronic expansion valve in the 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. In the prior art, when the air conditioner is running, the opening of the electronic expansion valve is usually adjusted based on the difference between the real-time discharge temperature of the compressor and the target discharge temperature. [0003] In the electronic expansion valve control method, the selection of the target exhaust temperature is extremely...
