Air Handling Unit Selection and HVAC Equipment selection is as much an Art as it is a Science.
You start with the desired – or calculated – capacity of air conditioning and heating the unit must provide. Then select which AHU manufacturer to base the design and specification.
It is prudent to compare the dimensions and weights of several manufacturers to ensure the installed unit fits within its allowed space. Select which options and accessories the unit must have to meet the desired performance, maintenance, and control.
Finally, schedule the unit(s) on the construction plans and in the specifications. Coordinate size, weight, configuration, duct, and piping layouts with the Owner, Architect, and the other engineering disciplines simultaneously during design and selection. This Mechanical Engineering coordination is essential to the successful design and installation of an air handling unit system.
Worksheets
The Air Handling Unit Selection Worksheet is designed to be used simultaneously and in conjunction with the HVAC Load Calculation Worksheet, although it can stand alone if you know the conditions you are attempting to satisfy.
The AHU Selection Worksheet uses sensible load, latent load, and total load to provide the remaining variables to select air handling units. Use this tool for small single-zone fan coil units and split systems up to large, industrial-type air conditioning systems.
The worksheet also has a section for estimating internal, external, and total static pressure so that fan selections can be made. By using these two worksheets, you can realize significant increases in overall profitability and accuracy in scheduling of equipment.
The AHU Selection Worksheet is also a great resource to use while going through the HVAC Design Fundamentals Course.
