ME 439 HVAC Design
Include the following information/deliverables.
HVAC & Duct System:
Layout (line drawings)
Show all duct sizes and cfm’s – use round ductwork
Show diffuser locations and type (use a schedule – Titus Brand)
Show terminal units (VAV, FCU, etc.) (use a schedule – Trane Brand)
Show primary HVAC units on layout (use schedule – Trane Brand)
Hand in one cut sheet per unit type (diffusers, terminal units, boiler, AHU, etc.)
For the schedule(s) of all unit types, include data such as cfm, gpm, Btu/hr heating, Btu/hr cooling, pressure loss, and any other relevant data.
On a separate sheet, show piping layout – include gpm and pipe size
Show any equipment the piping is connected to
Load Layout Diagram: For each zone, on a separate sheet, include the following:
Show terminal units and branch ductwork/diffusers
For each zone, list your calculated design heating and cooling loads and fresh air
· you may integrate a schedule with this diagram
List how you will control temperatures in the zones
List if/how you will control air and hydronic variations of flow and temperature
Equipment shut off / turn on control and schedule
Energy & Cost Calculations:
List how much energy you expect your HVAC system to use per year.
List how much energy cost you expect your HVAC system to use per year.
List how much energy (MMBtu/yr) you expect your HVAC system to use per year.
List how much energy (MMBtu/sqft) you expect your HVAC system to use per square foot.
All calculations, sample calc, info, spreadsheets, assumptions, references
