Abstract

In this paper, with an actual example of a district cooling project, by simulation and theoretical calculation, analyses the load characteristic of the District Cooling System and the operation characteristic of water chillers. And then, based on the principle of ice-storage priority and refrigeration units running with high load rate, control strategies under different load characteristic conditions were put forward. It is obtained that: the comprehensive energy efficiency ratio of system can reach 3.29 in summer with optimal operation strategy, and the operation cost for the production of 1 kWh cold is 0.22, 0.21, 0.18 and 0.15 accordingly under 100%,75%, 50% and 25% of the full load.
