Abstract

The invention discloses a regulation and control method, device and equipment for an electronic expansion valve. The regulation and control method comprises the following steps that 1, the current working condition is in a low-temperature working condition is confirmed; 2, the actual exhaust temperature and the target exhaust temperature are compared, and the opening degree of the electronic expansion valve is adjusted according to the comparison result; and 3, the current opening degree of the electronic expansion valve is maintained to reach the preset time, and then the step 2 is executed.According to the regulation and control method for electronic expansion valve, whether the environment temperature is in a low-temperature area or not is detected, after the opening degree of the electronic expansion valve is adjusted, the opening degree maintaining time of the electronic expansion valve is adjusted, the maintenance time is prolonged to avoid the electronic expansion valve is adjusted again when the exhaust temperature is not stable, so that the exhaust duration is not stable, parameters such as superheat degree of the air conditioning system are influenced, and reliability ofoperation of the low-temperature environment air conditioner is enhanced.

Description

technical field [0001] The present invention relates to the field of unit technology, in particular to a control method, device and equipment for an electronic expansion valve. Background technique [0002] In the prior art, the control method for the electronic expansion valve of air conditioners and other equipment mainly adopts the following process: according to the target exhaust temperature in the control logic, the opening of the electronic expansion valve is adjusted. For example: when the indoor ambient temperature is 25°C and the outdoor temperature is 35°C, the target exhaust temperature in the control logic is set to 80°C, if the actual exhaust temperature is lower than the target exhaust temperature, the electronic expansion valve opening will be reduced Maintain for a certain period of time to determine whether the exhaust gas temperature has reached the target exhaust temperature, and then decide whether to reduce the opening degree again and what the value of...
