Abstract

The invention provides a control method and system for preventing an air conditioner from freezing, electronic equipment and a medium. The control method comprises the steps that the coil pipe temperature and the preset temperature are obtained; judging whether the air conditioner triggers a freezing protection mode; adjusting the running state of the air conditioner based on the working mode triggered by the air conditioner; the operation state comprises a variable shunting state and a fixed shunting state; during variable shunting, a refrigerant in a heat exchanger of the air conditioner adjusts the shunting state according to the working mode of the air conditioner; and during fixed shunting, the shunting state of the refrigerant in the heat exchanger is fixed. According to the control method for preventing the air conditioner from freezing, the coil pipe temperature and the preset temperature are obtained firstly, whether the air conditioner triggers the freezing protection mode or not is judged based on the coil pipe temperature and the preset temperature, and the operation state of the air conditioner is adjusted based on the working mode triggered by the air conditioner, so that the air conditioner is switched between the variable shunting state and the fixed shunting state. And the shunting state of the heat exchanger is changed, so that the air conditioner cannot be shut down due to freezing protection in a certain low-temperature interval.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method, control system, electronic device and medium for preventing the freezing of air conditioners. Background technique [0002] Air conditioners are now a must-use electrical appliance for home and office, especially in summer and winter, air conditioners are used for a long time. The air conditioner can cool in summer and heat in winter, and can adjust the indoor temperature to be warm in winter and cool in summer, providing users with a comfortable environment. [0003] When the air conditioner operates in a low temperature and high humidity environment, the air conditioner performs freezing protection to protect the internal machine and prevent the evaporator from frosting. However, in a high humidity environment, it is easy to cause freezing because the air conditioner frequency is not reduced in time, or the performance of the air conditio...
