Abstract
Team 20 of MECH4860 was paired with Sterling Industries Ltd., a local steel fabrication company and tasked with designing the HVAC for Sperling Industries’ anticipated 19,400 sq. ft. paint facility. Sperling Industries looks to take our design and estimated cost into consideration to see if their new paint facility is feasible. Multiple concepts were brainstormed and put against each other in pair wise selection matrices to determine which design would be best suited for this application. Between three energy sources and three air handling equipment, Team 20 had to select a final design from nine generated conceptual designs. After collaboration with Sperling Industries, Team 20 chose to proceed into final design with the concept that included the use of a propane-burning make up air unit (MUA). The final design incorporated calculations and finer design details that were overlooked in the concept selection phase. First, the exhaust requirement was determined for the building, which depended heavily on the lower flammability limit of the paints used in the paint area. Team 20 decided to implement two MUA’s on the basis of system control; the flexibility to turn off one MUA during the periods while the paint booth was not running overweighed the increased capital cost of separate MUA’s. Second, the MUA’s were sized as per the air volume required by the exhaust and heating calculated by CAN-QUEST needed to keep a comfortable, 25oC within the building. Third, exhaust equipment was specified and duct sizes and diffuser layout was selected. iii Team 20 chose to use two Engineered Air manufactured HE direct fire propane burning MUA’s, complete with M-TRAC controls, two Price Industries manufactured CWB belt driven sidewall exhaust fans, and Standard Tools and Equipment Co.’s custom sized semi-down draft paint booth with separate Greenheck CUBE-480 explosion proof upblast exhaust fan. The remaining spaces in the building are to be exhausted by Greenheck CWB-240 and CWB-300 explosion proof exhaust fans. The building HVAC will connect with pneumatic controls for simple operation and cost. The total estimated equipment cost for the new paint facility is $127,683. To conclude, the HVAC design was intended to...
