Problems solved by technology
[0004] The embodiment of the present application provides an air conditioner and its control method and device, which solves the problem of reducing the operating frequency of the compressor or intermittently shutting down the air conditioning system in the prior art when the air conditioner is operating under high temperature conditions. When the operating pressure is high, it is easy to reduce the cooling capacity of the air conditioner, resulting in a decrease in the comfort of the indoor environment, which greatly reduces the user experience. The operating pressure of the system can not only realize the high temperature protection of the air conditioner, but also ensure the cooling capacity of the air conditioner under high temperature conditions, thereby improving the comfort of the indoor environment and improving the user experience

Embodiment Construction
[0028] When the application recognizes that the air conditioner is operating in cooling mode under high temperature conditions, the operating pressure of the air conditioning system can be reduced by controlling the overfrequency operation of the fan in the outdoor heat exchanger, which can not only realize the high temperature protection of the air conditioner, but also ensure that the air conditioner The cooling capacity of the device under high temperature conditions improves the comfort of the indoor environment and improves the user experience.
[0029] In order to better understand the above-mentioned technical solutions, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth ...

The present application discloses an air conditioner and its control method and device, wherein the control method of the air conditioner may include the following steps: identifying that the air conditioner is operating in cooling mode; detecting the outdoor ambient temperature, and identifying that the outdoor ambient temperature is greater than or equal to the first Temperature threshold: control to increase the speed of the fan in the outdoor heat exchanger to be greater than or equal to the first preset speed. Therefore, under high temperature conditions, the operating pressure of the air conditioning system can be reduced by controlling the overfrequency operation of the fan in the outdoor heat exchanger, which can not only realize the high temperature protection of the air conditioner, but also ensure the cooling capacity of the air conditioner under high temperature conditions , thereby improving the comfort of the indoor environment and enhancing the user experience.
Description
technical field [0001] The present application relates to the technical field of air conditioner control, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] In order to meet the diverse needs of users, air conditioners often need to operate in special environments, such as high temperature and small spaces, which will bring great harm to the air conditioning system itself. For example, when the air conditioner operates in cooling mode under high temperature conditions, the high indoor and outdoor temperature will cause the operating pressure of the air conditioning system to be too high. At the same time, the discharge temperature and return air temperature of the compressor in the air conditioning The temperature of each module in the control system will rise, reducing the reliability and service life of the air conditioning system. [0003] In the related art, in order to solve the ab...
