Comparative analysis of centralized heating and cooling system based on sewagesource heat pump system with a traditional system in hot summer and warm winter zone

Taking an urban complex as an example, analyses the feasibility of the district energy system based on sewagesource heat pump for heating and cooling in hot summer and warm winter zone, and compares it with a regional energy system of traditional heating and air conditioning. The results show that the district energy system based on sewagesource heat pump for heating and cooling still has a certain energy saving and economic advantage even in South China where mainly uses cooling. In additions, discusses the system application problems in South China.
