The invention relates to the technical field of air conditioners, particularly provides an air conditioner and a control method thereof, and aims to solve the problem that normal use of an existing air conditioner is affected due to false alarm and shutdown after startup during refrigeration operation in winter. In order to achieve the purpose, the air conditioner is arranged to be capable of obtaining the outdoor air speed, and the control method of the air conditioner comprises the steps that after the air conditioner enters a refrigeration mode, the outdoor temperature and the outdoor air speed are obtained; according to the outdoor air speed and the outdoor temperature, the operation duration, the operation frequency, the corresponding temperature rise threshold value and the current range of a compressor of the air conditioner are determined; the compressor is controlled to operate at the determined operation frequency for the determined operation duration, and the exhaust temperature rise value and the current value of the compressor are obtained; judging whether the exhaust temperature rise value is smaller than a temperature rise threshold value and whether the current value is in a current range; if the exhaust temperature rise value is smaller than the temperature rise threshold value and the current value is not within the current range, an alarm and / or shutdown are / is given out, otherwise, the air conditioner is controlled to operate normally, and false alarm and shutdown of the air conditioner are avoided.
Description
technical field [0001] The invention relates to the technical field of air conditioners, and specifically provides an air conditioner and a control method thereof. Background technique [0002] With the continuous improvement of people's living standards, air conditioners have become an essential household appliance in people's lives. Usually, people use air conditioners to cool down the ambient temperature in summer, thereby improving the comfort level of the user's environment. During daily use, there will be situations where the compressor exhaust temperature is low due to insufficient refrigerant in the refrigerant circulation circuit, and the cooling efficiency of the air conditioner is low or even unable to cool. In order to avoid the situation that the air conditioner is still cooling when the compressor exhaust temperature is low and the cooling efficiency is low or even unable to cool, the existing air conditioner will detect the compressor after the start-up opera...
