As the operation and performance of the air handling process are affected by various complex factors, such as climate condition, building usage, room control parameter, performance of air handling equipment itself that it is very difficult to analyze the process performance and energy consumption by whole year simulation. Single node (design day) calculations or by experience is commonly used method for designing the air handling process for a HVAC system. This paper describes a newly developed whole year simulation method for estimating the operation performance, the percentage of satisfaction and energy consumption of air handling processes. This new method could simulate, in detail, a large range of air handling process equipment, such as cooling and heating coils; and under different control strategies and schemes. A case study is given in this paper to demonstrate the practical use of this new whole year’s simulation method. Key Word: air handling process, HVAC equipment, whole year an
