Analysis of energy saving technology for central air conditioning water system operation

Central air conditioning is an important part of public buildings, but also one of the main energy consumption equipment. Air conditioning energy consumption generally accounts for more than 40% of the overall building energy consumption. Energy saving transformation of central air conditioning in public buildings is imminent and has great potential. This paper expounds the working principle of central air conditioning water system and process, analyses the advantages and disadvantages of different control methods of chilled water system and cooling water system, summarizes the six problems of central air conditioning operation, and analyses the energy consumption sources of the central air-conditioning system, and finally puts forward the improvement measures of energy saving in the operation of the air-conditioning water system. It provides reference for energy saving transformation of central air conditioning system.
