Air Handling Unit Design Worksheet

Air Handling Unit Design Worksheet integrates with the HVAC Load Calculation Worksheet – HVAC Load Calculator. This worksheet will assist the design engineer in accelerating initial design decisions and system selection. The simple and straight forward worksheet layout allows the design engineer to input, change and manipulate multiple air handling unit variations to arrive at a suitable air handling unit selection. The output from the Air Handling Unit Design Worksheet is a one-page form showing all the pertinent data and design conditions needed to accurately select the proper air handling unit equipment to satisfy the space conditions.

Other Air Handling Unit Design Worksheet Programs

There are other Air Handling Unit Design Worksheet programs on the market that require more data input, produce large quantities of output, are very specific in terms of air handling unit selection. These programs are either manufacturer specific or are very expensive. The use of these programs is often necessary and beneficial when it comes time to perform the actual equipment sizing, selection, and specification. A design engineer who doesn’t spend the time manipulating air handling unit configurations would not be providing the building owner with professional service. It is imperative that the most realistic and accurate systems and equipment be designed and selected for the building so that the owner receives the most economical and functional building possible.

But due to budget or time constraints, there are times when the more sophisticated unit selection programs are not fiscally reasonable. For example, in the early stages of the design process, when the owner, architect, and engineer are meeting to determine the best course of design to pursue, it is important to understand the impact of the HVAC system equipment on the overall design especially as it relates to space requirements. It becomes convenient to have a method by which the engineer can estimate these space requirements by quickly sizing the equipment required based on the current architectural design and extrapolating out to come up with mechanical room sizes, access into/out of and overall location within the building.

It’s also at this stage of the design when preliminary decisions can be made by the owner, architect and engineer about the type of systems that will be utilized in the current design. Depending on the total load, the desired system control, the required space setpoints, etc., the type of systems can be narrowed down or possibly even selected. Further information and design considerations on the Air Handling Unit Design Worksheet can be found on the HVAC Load Calculation Worksheet – HVAC Load Calculator page.
