Abstract : This paper introduces the application of inverter energy-saving technology in central air conditioning systems. Taking a shopping mall as an example, it analyzes the energy-saving performance of the main equipment in the air conditioning system and proposes corresponding energy-saving technical improvement schemes. Keywords : Central air conditioning system; Inverter; Energy saving 0 Introduction Since the reform and opening up, the rapid development of the national economy has made China the world's second largest energy consumer, but China's comprehensive energy utilization rate is very low. Data shows that China's energy consumption per unit of GDP is 6 to 10 times higher than that of advanced countries, and the energy consumption per unit of product is 50% to 100% higher than that of foreign countries. Therefore, how to save energy and reduce consumption has become an urgent issue we face. According to available data, air conditioning systems account for about 50% of the energy consumption of buildings. Taking a shopping mall in Shenzhen as an example, this paper proposes some energy-saving technical improvement suggestions for the central air conditioning system of the mall, for your reference. The main equipment of the shopping mall's central air conditioning system is shown in Table 1.
