Abstract

The invention provides a control method of an electronic expansion valve, an air conditioner and computer equipment. The method comprises the steps that a current operation mode is detected; when it is detected that the current operation mode is a refrigerating mode, external environment temperature and condensation temperature during operation are obtained in real time; the superheat degree is calculated according to the external environment temperature and the condensation temperature; and the opening degree of the electronic expansion valve is controlled according to the superheat degree. The control method has the advantages that the current operation mode is detected, the superheat degree is calculated according to the external environment temperature and the condensation temperaturewhich are obtained in real time when the current operation mode is the refrigerating mode, and the opening degree of the electronic expansion valve is controlled according to the superheat degree, sothat the electronic expansion valve is dynamically controlled according to the real-time situation, and the air conditioner operates in a better state all the time.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a control method for an electronic expansion valve, an air conditioner and computer equipment. Background technique [0002] At present, the pipeline of the subcooling system of the air conditioner is too complicated, and the auxiliary air injection circuit needs to add an electronic expansion valve. However, there is no specific control method for the control of the electronic expansion valve. Generally, the opening of the electronic expansion valve is directly fixed, which will lead to The valve step control of the electronic expansion valve is inaccurate, and it cannot be linked with the real-time situation of the air conditioner in real time. Under high water temperature, the exhaust and condensation pressure will be too high, and there is a risk of trip protection due to excessive exhaust and pressure. Therefore, an electronic expansion valve is urgently needed. Control metho...
