Study and Practice on Hvac System Commissioning

HVAC commissioning has come to be recognized as most important process needed for design, construction and operation and maintenance of HVAC system to realize owners true project intent and establish energy saving and sustainable operation and management of the building system. The author first introduce basic concept of commissioning and its actual procedure to be executed at each phase of building project, introduces brief history on the progress of commissioning concept and discusses differences among similar processes, and then introduces the author’s experience of initial commissioning project to show actual procedures of commissioning process. Among tools expected to well perform each style of commissioning business, system simulation program will be useful for design commissioning, post acceptance commissioning and continuous commissioning. Five typical programs are compared about their functions and energy calculation results in order to verify availability of system simulation programs as a commissioning tool.
