[0002] Precision air conditioning, also known as constant temperature and humidity air conditioning, is a professional-grade air conditioning system designed specifically for specific applications that have strict requirements on indoor environmental parameters. Compared with conventional household or commercial air conditioners, precision air conditioners have higher control accuracy, stability, operating efficiency and stronger adaptability to ensure that ideal temperature and humidity levels are maintained under various complex working conditions, and often also include air purification, airflow organization control, remote monitoring and other functions.

[0003] The Chinese utility model patent with publication number CN215983204U disclosed a central air conditioner lifting and translation auxiliary device on March 8, 2022, including: a first support plate, whose end face is fitted on the side wall of the second support plate, a horizontally arranged docking hole is opened at the center of the end of the first support plate, and a connecting block is slidably inserted in the docking hole, and the connecting block is vertically installed on the side wall of the second support plate; it also includes: an outer cylinder, which is symmetrically installed on both sides of the first support plate and the second support plate, and 4 outer cylinders are vertically arranged, and a moving column is fitted on the inner wall of the outer cylinder, and the two are coaxially arranged; a roller assembly, whose top is fitted on the bottom surface of the moving column, and a rotating shaft is vertically connected at the top center of the roller assembly. The central air conditioner lifting and translation auxiliary device occupies less space during use, and the device is more flexible, and the user can freely and accurately control the mobile central air conditioner to translate in multiple directions.
