Embodiment Construction
[0021] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.
[0022] It should be noted that in the description of the present invention, the terms "first", "second", "third", "fourth", "fifth" and "sixth" are only used for understood as indicating or implying relative importance.
[0023] Based on the fact that the indoor units, outdoor units and online pipes of the existing air conditioners are easy to freeze, which leads to the deterioration of the cooling effect of the air conditioners, or problems such as water leakage and pipe cracks of the air conditioners. The invention provides a control method of an air conditioner, which aims to avoid freezing of an indoor unit, an outdoor unit and an...

The invention relates to the technical field of air conditioners, and aims to solve the problem that an indoor unit, outdoor unit and unit connecting tube of an air conditioner are easy to freeze, thereby making the air conditioning refrigeration effect worse, or causing the phenomenon of leaking, pipe cracking and the like. Therefore, the invention provides a control method for the air conditioner, the air conditioner comprises a compressor and an outdoor unit, and the control method comprises the steps that an air intake temperature of the outdoor unit is acquired; and the frequency of the compressor is selectively adjusted according to the air intake temperature of the outdoor unit. The control method for the air conditioner has the advantages that the operating frequency of the compressor can be adjusted according to the temperature interval in which the air intake temperature of the outdoor unit is located, so as to avoid the freezing of the indoor unit, outdoor unit and unit connecting tube of the air conditioner, thereby effectively solving the problem that the indoor unit, the outdoor unit and the unit connecting tube of the air conditioner are easy to freeze, and the stability and reliability of the air conditioner operation are also improved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a control method of an air conditioner. Background technique [0002] When the air conditioner is in cooling operation, due to various reasons such as low indoor and outdoor ambient temperature, long piping connections, failure of the indoor unit coil temperature detection device, and lack of fluorine, the indoor unit, the connecting pipe, and the outdoor unit will freeze, which will cause the cooling effect. Bad phenomena such as poor, water leakage, pipe cracks, etc., seriously affect the user experience. [0003] In the prior art, an indoor unit coil temperature sensor or a pressure switch is generally used for anti-freezing control. The disadvantages of this control scheme are as follows: First, the indoor unit coil temperature sensor is prone to failure (such as damage or wrong insertion, etc.), so that it cannot be used. Accurately detect the temperature,...
