Operation economy analysis of the chilled water storage reform programs on central air conditioning system of a building

In this paper, a chilled water storage reconstruction program and its running strategy were proposed combining with the result of energy efficiency test on a building central air conditioning system, and compared operation cost before and after the reconstruction under the running condition and cooling load during test. The analysis results showed that the implementation of this reconstruction program will not only shift some load during the day but also can significantly save operation costs.
