Synthetic Evaluation Study on AC Systems within office and business building by DeST software

摘要

A synthetic evaluation study on AC (Air Conditioning) Systems within office and business building is made by using DeST (Building Environment Design Simulation Toolkit) software (Developed by QingHua University) and orthogonal experiment method. Many useful analysis results of the AC systems can be obtained such as the year electricity consumption, the year gas consumption, the year consumption amount of "Primary Energy", the year average COP, the year average load ratio, the discharge amount of sensible heat to outdoor atmosphere in summer, and the year discharge amount of some main "Green House Effect" gases(CO_2, SO_x, NO_x due to "Primary Energy" consumption) to outdoor atmosphere. Both of energy consumption characteristics and environmental effect of air conditioning systems, and their relationship with variety of parameters of architectural structure and type can be well known. All results we made are helpful to get guidance on the equipment selection, helpful to the operational mode selection of air-conditioning systems and the parameter selection of the architectural structure and type.
