ENERGY FLOW ANALYSIS OF ELECTROMECHANICAL PRODUCTS FOR ENERGY SAVING

摘要

In many situations,energy saving measures may make negative effects on product performance.In order to address the conflict between energy saving and performance optimization,the energy flow model is built to systematically express the transmission,distribution,and change of energy.On the basis of the energy flow model,two indices are developed to guide the energy saving process while guarantee the performance.The first index is the performance pertinence,a measure for the influence of component's design changes on performance.The second index is the performance margin,a measure for the optimization potential of components.The two indices are used to solve the conflict by identifying the components that should be optimized.Finally,the proposed method is illustrated by a case study of a split air-conditioner's outdoor unit.
