Optimal Distribution of Chiller Design Capacity in District Cooling System

Kang Ying-zi1 Hua Ben2(1.School of Automotive Engineering,South China University of Technology,Guangzhou 510640,Guangdong,China; 2.Key Laboratory of Enhanced Heat Transfer and Energy Conservation of the Ministry of Education,South China University of Technology,Guangzhou 510640,Guangdong,China)  
According to the principle of minimizing the life cycle cost of chiller systems,this paper proposes an optimal model considering the variation of all-year cooling load to distribute the design capacity among different types of chillers in the district cooling system.The results of a case study show that(1) for a district cooling system with both the electrical and the Absorption chillers as the cooling sources,if the electricity and steam prices are both determinate and the cooling load are constant,there is an optimal distribution of design capacity between the two kinds of chillers;(2) both the electricity price and the steam price influence the optimal distribution of design capacity,especially the former;and(3) the limitation of steam supply is an important factor affecting the optimal distribution of design capacity and the life cycle cost of chiller systems.
