Analysis of Energy-saving Design Points for HVAC Systems in Large-scale Commercial Complexes
Abstract：To study the energy-saving design points of HVAC systems in large-scale commercial complexes, this paper analyzes the energy efficiency test data of temperature and humidity, chilled water units, and cold source systems based on the specific situation of a complex project. It discusses the main problems existing in the system and proposes targeted energy-saving design schemes, such as replacing high-efficiency chilled water units, optimizing the configuration and control strategy of the chilled water system, improving the performance of the cooling water system, and implementing intelligent control strategies. The results show that after the renovation, the COP of the cold source system has significantly improved, with an annual energy-saving cost of approximately 178,000 yuan, providing a reference for achieving efficient operation of the HVAC system in commercial complexes.
