Problems solved by technology
[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the existing air conditioners are difficult to accurately judge the freezing condition of the indoor unit only based on the temperature of the inner coil, and the corresponding anti-freezing conditions have not been set according to the different freezing conditions of the indoor unit. Mode problem, the present invention provides an indoor unit anti-freezing control method for an air conditioner, the indoor unit anti-freezing control method includes: when the air conditioner is in cooling operation, obtain the fan current and Coil temperature: according to the corresponding relationship between the fan current of the indoor unit and the coil temperature, selectively make the air conditioner enter the corresponding anti-freezing mode of the indoor unit

Embodiment Construction
[0022] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the various steps of the method of the present invention are described in a specific order in the present application, these orders are not limiting, and those skilled in the art can perform the steps in different orders without departing from the basic principles of the present invention. Follow the steps described.
[0023] Based on the existing air conditioner proposed in the background art, the freezing condition of the indoor unit is judged only by the temperature of the inner coil, which easily leads to a problem of misjudgment. The present invention provides an indoor unit anti-freezing control method for an air condi...

The invention belongs to the technical field of air conditioners, and particularly relates to an indoor anti-freezing control method for an air conditioner and the air conditioner. The invention aimsto solve the problem that an existing air conditioner can not accurately judge the freezing condition of an indoor unit only according to the temperature of an inner coil pipe, and the problem that the corresponding anti-freezing modes are not yet set according to different freezing conditions of the indoor unit. The indoor anti-freezing control method comprises the following steps that when the air conditioner is operated, fan current and coil pipe temperature of the indoor unit are acquired; the air conditioner is selectively enabled to enter the corresponding indoor anti-freezing mode according to the corresponding relation between the fan current and the coil pipe temperature of the indoor unit; so that the air conditioner can judge the freezing condition of the indoor unit according to the corresponding relation between the fan current and the coil pipe temperature of the indoor unit. According to the air conditioner, the most appropriate anti-freezing mode is selected according to different freezing conditions, so that on the basis of enhancing the deicing effect, and energy can be further effectively saved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an indoor unit anti-freezing control method for the air conditioner and the air conditioner. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air conditioners have become an essential device in people's lives. Generally, an air conditioner includes an indoor unit, an outdoor unit, and a circulation loop for connecting the indoor unit and the outdoor unit. The heat exchange medium in the air conditioner continuously exchanges heat between the outdoor unit and the indoor unit through the circulation loop, thereby achieving a change in room temperature. Effect. Taking the cooling operation of the air conditioner as an example, the coil of the indoor unit is always at a low tem...
