[0002] Air conditioning system, also known as air conditioner, refers to a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. Nowadays, in addition to the basic functions of cooling and heating, the humidification performance of air conditioners is also becoming more and more important.

[0003] In cold weather, when users use air conditioning systems or gas heating, the indoor environment will become drier. In such a dry environment, human skin will become dry and respiratory discomfort will occur, which will not only fail to ensure the user's comfort, but also directly affect the user's health. In order to maintain the appropriate humidity in the indoor environment, the air conditioning humidification function needs to be turned on. However, since the cold ambient temperature may be lower than the freezing point of water, the water in the humidification tank of the air conditioning system will freeze, which will bring safety hazards.

[0004] The existing air-conditioning humidifying water tank antifreeze control method is to detect the current temperature of the water in the humidifying water tank by configuring a temperature sensor somewhere in the humidifying water tank, and when the current temperature reaches the antifreeze temperature, heat the water in the humidifying water tank to prevent freezing. However, the existing air-conditioning humidifying water tank antifreeze control method only uses the temperature sensor to detect whether the current temperature of the water reaches the antifreeze temperature to determine whether the water in the humidifying water tank is frozen. Since the temperature sensor is set at a certain position in the humidifying water tank, the current temperature detected by it cannot accurately represent the current temperature of the water at each position in the humidifying water tank, resulting in misoperation of the air-conditioning humidifying water tank antifreeze control method, thereby affecting the accuracy of the operation of the air-conditioning humidifying water tank antifreeze control method.
