Air-cooled direct expansion precision air conditioners are most widely used in data centers. Due to the large differences between design parameters and actual operating conditions, the heat and humidity environment of the computer room is difficult to achieve the best state. Presents an air conditioning cluster control method that optimizes the airflow organization, adjusts the operating conditions of the air conditioning, reduces the working time of the fan, reduces the frequency of compressor start and stop, and finally realizes the efficient and stable operation of the heat and humidity environment of the computer room.
