As the subject of the dissertation, the design selected the two models of ed3100-4t0220m and ed3100-4t0185m in the current national-produced variable brand. The central air-conditioning system is indispensable in modern plant enterprises, office buildings, businesses, hotels, etc. The central air-conditioning system is a system engineering project consisting of components such as wind, water pumps, air-conditioning units, wind tubes, etc. The system is divided into sub-systems such as refrigerated water systems, cooled water systems, air-conditioning hosts and cooling tower winders. The central air-conditioning system consists of these large subsystems. This will certainly increase its energy consumption significantly. It is estimated that central air conditioners consume 40-60 per cent of the energy of buildings throughout the year and that the energy consumed by their equipment is mainly used in cold sources and delivery systems, so that the cold sources and transport component of air conditioners are key to the self-controlled energy-saving design of air conditioners. Due to the limited experience and knowledge of the designer, there are inevitable gaps in the design, which teachers are expected to understand and correct.
