Analysis of Energy Factor Effectiveness in Air-Conditioning Refrigeration System

Abstract

This paper deals with the energy-saving product design involving the product energy property into design process. On the basis of the energy factors concepts, the paper analyzes the extraction process and energy effectiveness model of energy factors. To study the air-conditioning refrigeration system, the paper establishes the energy information model, recognizes the crucial and controllable energy element and extracts the energy factor set C = {compressor volumetric efficiency λ, motor efficiency ηd, power frequency fd, heat transfer performance coefficient φ, finned lateral general area Ao}. Then it makes a further decomposition of coupling energy factors λ, φ and finds out the corresponding design parameter. In the end, the paper maps the energy factors and design parameter into design process, establishes the energy effectiveness model and presents several measurers for decreasing the energy consumption during the actual use of air-conditioner.
