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 cannot perform different defrosting methods according to different situations, the heating effect of the existing air conditioners is easily affected by the frosting phenomenon of the outdoor unit. Seriously affecting the problem, the present invention provides a defrosting control method for an outdoor unit of an air conditioner, the defrosting control method includes: when the air conditioner is in heating operation, obtaining the suction pressure of the air conditioner And the coil temperature of the outdoor unit; according to the suction pressure of the air conditioner and the coil temperature of the outdoor unit, selectively make the air conditioner enter the corresponding defrosting mode of the outdoor unit

Embodiment Construction

[0019] 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.

[0020] Based on the background technology, each existing air conditioner can only implement a single defrosting control method, but cannot implement different defrosting methods according to different frosting conditions, resulting in the heating effect of the existing air conditioner being very easy A probl...

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner and an outdoor unit defrosting control method thereof. The air conditioner and the outdoor unit defrosting control method aim to solve the problems that an existing air conditioner cannot perform different defrosting methods according to different situations, so that the heating effectis prone to being seriously affected due to the fact that an outdoor unit has the frosting phenomenon. Therefore, the outdoor unit defrosting control method comprises the steps that the air suction pressure of the air conditioner and the coil pipe temperature of an outdoor unit are acquired when the air conditioner is in heating operation so as to judge the frosting degree of the outdoor unit; andthe air conditioner is selectively enabled to enter the corresponding outdoor unit defrosting mode according to the air suction pressure of the air conditioner and the coil pipe temperature of the outdoor unit, thus, the air conditioner can select an optimal defrosting mode according to the frosting degree of the outdoor unit, and then the problems that for the existing air conditioner, the heating effect is prone to being seriously affected due to the fact that the selected defrosting mode and the actual frosting condition are not matched is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner and a defrosting control method for an outdoor unit thereof. 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. Take the heating operation of the air conditioner as an example, the coil of the outdoor unit is always in a low temperature state...
