Document Type and Number:
WIPO Patent Application WO/2024/027129
Kind Code:
A1
Abstract:
The present application relates to the air conditioning technology, and provides a control method and apparatus for air conditioner overheat protection, and an air conditioner. The control method comprises: acquiring a first temperature of an evaporator in an indoor unit of an air conditioner, a first mode of an air deflector in the indoor unit, and a first rotation speed of a fan in the indoor unit; if it is determined that the first temperature is greater than or equal to a preset threshold, adjusting the mode of the air deflector and the rotation speed of the fan according to the first mode and the first rotation speed, and acquiring a second temperature of the evaporator; and if it is determined that the second temperature is greater than or equal to the preset threshold, starting a preset overheat protection mechanism. The present solution provides an overheat protection control method capable of improving the heating effect of air conditioners to a certain extent. After the temperature of the evaporator reaches a set temperature, firstly, by adjusting the rotation speed of the fan and the mode of the air deflector, hot air blown out by the air conditioner can better exchange heat with indoor cold air, then the temperature of the evaporator is collected, and the overheat protection mechanism is started after the temperature reaches the set temperature.
