Abstract

As the global energy demand continues to soar, China, being a major energy consumer, is confronted with a severe energy situation. In cold regions, winter heating is a crucial element to ensure the normal living and working conditions of residents. However, traditional heating systems are fraught with problems during operation, such as energy waste and suboptimal heating performance. This paper focuses on the indoor thermal environment of various buildings in a university in Zhangjiakou, a cold region, during the heating season. Field measurements of the indoor thermal environment were conducted, and the supply and return water temperatures of the heating system were investigated. A thorough analysis of the measured data was performed to reveal the operating characteristics and existing issues of the heating system. Targeted optimization strategies were then proposed. The findings of this research are of great significance for improving the efficiency of distributed heating systems and enhancing the indoor thermal environment.
