Air conditioner and control method and device thereof

Abstract

The invention discloses an air conditioner and control method and device thereof. The control method of the air conditioner comprises the following steps of identifying the operation of the air conditioner in a refrigeration mode; detecting the outdoor environment temperature, and identifying that the outdoor environment temperature is larger than or equal to a first temperature threshold value; and controlling the rotating speed of a fan in an outdoor heat exchanger to be larger than or equal to a first preset speed. Under the high-temperature working condition, the operating pressure of an air conditioning system is reduced by controlling the ultra-frequency operation of the fan in the outdoor heat exchanger, so that the high-temperature protection of the air conditioner can be realized,the refrigerating capacity of the air conditioner under the high-temperature working condition can be ensured, the comfort of the indoor environment is improved, and the user experience degree is improved.

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...

AI Technical Summary

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
