Air conditioner, control method and device thereof

Abstract

The invention discloses an air conditioner, and a control method and device thereof. The air conditioner comprises an indoor unit; the indoor unit comprises a case, and a fan module and an electric auxiliary heating module which are arranged in the case; an air outlet and an air inlet are formed in the case; an upper air inlet area and a lower air inlet area are formed in the air inlet; and an upper air outlet area and a lower air outlet area are formed in the air outlet. The control method comprises the following steps that when the air conditioner is started to run in a heating mode, the fanmodule is controlled to be started, and the electric auxiliary heating module is controlled to work; an air inlet temperature of the upper air inlet area and an air inlet temperature of the lower airinlet area are acquired, and a temperature difference value is acquired according to the air inlet temperature of the upper air inlet area and the air inlet temperature of the lower air inlet area; when the running time of the heating mode in which the air conditioner is started to run reaches first preset time, the temperature difference value is judged; and when the temperature difference valueis greater than the first preset temperature difference, the electric auxiliary heating module is controlled to stop working, and an indoor vertical temperature difference is reduced accordingly, sothat the indoor thermal comfort is improved effectively.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people's requirements for living environment are gradually increasing. When the user turns on the cooling or heating function of the air conditioner, the purpose is to keep the indoor temperature within a comfortable range. However, when the heating mode is turned on, because the proportion of the hot air flow is small, it is easy to rise, so the hot air is difficult to reach. ground, resulting in hot head and cold feet, affecting user comfort and increasing power consumption in heating mode. [0003] In related technologies, wall-mounted air conditioners all use cross-flow fans. For wall-mounted air conditioners that use vertical single cross-flow fans,...

AI Technical Summary

Problems solved by technology

However, the above method has the following disadvantages: increasing the radian of the upper and lower swing leaves will affect the appearance of the whole machine; increasing the fan speed will increase the noise, and the heating speed of the air conditioner can be improved by increasing the fan speed, but not necessarily Improve the problem of indoor temperature stratification
