Problems solved by technology

Moreover, if the lower air outlet of the cabinet air conditioner is closed, it is easy to cause the lower evaporator to fail to exchange heat with the indoor air, so that the temperature on the surface of the lower evaporator of the air conditioner gradually decreases, resulting in ice formation on the surface of the air conditioner evaporator

Abstract

The invention relates to the technical field of intelligent household appliances, and discloses an anti-freezing control method for an air conditioner evaporator. Two air outlets can be formed in the cabinet air conditioner, and a first evaporator and a first throttling valve are arranged on the cabinet air conditioner; after the first air outlet of the air conditioner is closed, the first temperature of a coil pipe on the first evaporator is obtained, when the first temperature is lower than the preset temperature, the opening degree of the first throttling valve is adjusted, so that the flow of a refrigerant flowing through the first throttling valve is reduced, so that the first temperature of the first coil pipe is increased, so that the surface of the first evaporator is prevented from freezing, and the first evaporator is prevented from freezing after the first air outlet is closed while a user experiences an air conditioner refrigeration mode through the second air outlet. The invention further discloses an anti-freezing device for the air conditioner evaporator and the cabinet air conditioner.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a control method and device for anti-freezing of an air conditioner evaporator, and a cabinet air conditioner. Background technique [0002] At present, with the improvement of people's living standards, people's requirements for air-conditioning cabinets are getting higher and higher. Existing air-conditioning cabinets generally only have one air outlet, and most of them are arranged on the upper part of the cabinet. The air outlet mode is relatively single, and the air outlet volume is small, which cannot meet the needs of the air outlet area and air outlet volume, so that the temperature of the indoor air cannot effectively and quickly reach the set temperature. In this regard, a cabinet air conditioner including upper and lower air outlets has appeared in the prior art. However, the existing cabinet air conditioners with double air outlets are usually...
