Practical Diagnostic Approach of Energy Consumption of AC Systems

Abstract

Due to the vast amount of energy consumption of AC (Air Conditioning) systems, the reasonable design, optimal operation and efficient management of AC systems are inevitable and necessary to the whole city energy management (CEM). To achieve these objectives, the verification of systematic characteristics (mainly refers to the systematic COP), practical approaches of energy consumption diagnosis of AC systems should be taken as the premises and the most elementary works. Itemized metering of the driving power of each compressor, pump and fan is recognized as a key process needed for optimal operation and maintenance of air conditioning systems. Based on AC commissioning principle, a practical diagnostic approach of energy consumption of AC system is established. The framework and general procedures of the practical approach is presented and introduced in this paper.
