Air conditioner and control method and device of air conditioner

Abstract

The invention discloses an air conditioner and a control method and device of the air conditioner. The air conditioner comprises an indoor unit. The indoor unit comprises a machine shell, an air handling module, multiple sets of air inlet adjusting assemblies and a switching valve. An air conditioning air flue is defined in the machine shell, and an air inlet is arranged on the machine shell. An upper air inlet area and a lower air inlet area are formed by the air inlet. The air handling module comprises a shell. A fresh air flue is defined in the shell. The method comprises the following steps that when the air conditioner operates by starting a heating mode, the air inlet is adjusted to be in the maximum air inlet state through the multiple sets of air inlet adjusting assemblies; the airinlet temperatures of the upper air inlet area and the lower air inlet area are acquired, and the temperature difference value is acquired; when the operation time reaches the first preset time, thetemperature difference value is judged; and if the temperature difference value is larger than the first preset temperature difference, the switching valve is controlled so as to control the air conditioning air flue to communicate with the fresh air flue, so that the indoor vertical temperature difference is reduced. The indoor heating power lamination phenomenon during heating operation of the air conditioner is effectively relieved, and therefore the indoor heat comfort is improved.

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,...

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
