ENERGY PERFORMANCE OF DISTRICT COOLING SYSTEMS IN SHANGHAI
District Cooling System (DCS) has been successfully applied in many countries, chilled water which is generated in a central refrigeration plant is delivered through a distribution network to support the air-conditioning systems in a district place. Because of the large scale production, the efficiency of refrigeration equipment is higher than that in individual buildings. In recent years, interests of DCS has been aroused in china for large scale of construction and under the pressure of energy saving. This paper describes a study on the feasibility research of implementing DCS in Shanghai, where is a typical subtropical climate in china. The paper will focus on detailed analysis of several main factors which influence the energy efficiency of DCS, and first costs, annual owning and operating costs, life cycle costs, return year and influence to environment of DCS and common system are analyzed and compared, and then a conclusion of the precondition for good energy performance is given.
