Methodology of determining minimum energy efficiency requirements for chillers

On the basis of the overall energy saving target for the public buildings, proposes a new method to determine the energy efficiency of chillers by considering the economics and technical feasibility of the equipments. Establishes the mathematical model and initial investiment model for the comprchensive performance of the chillers. By optimal simulation for energy consumption of public buildings with different types in different climate zones, obtains the minimum energy efficiency requirements of chillers in different climate zones, and conducts a comprchensive analysis of the minimum energy efficiency and the energy-saving effect.
