Energy efficiency measurement and analysis for heating system of a central energy station at a university in hot summer and cold winter zone

In south China, especially in hot summer and cold winter zone, there is the heating demand. According to the load characteristics of buildings at a university in hot summer and cold winter zone, establishes a district energy station based on ground-source heat pump system to cool in summer and to heat in winter. Combined with load analysis and thermal response test, determines the layout of buried pipe. The actual operation test result of energy efficiency shows that the COP of this system is 3.56, decreasing energy consumption by 61% compared to traditional heating system, and decreasing the pollutant emission.
