University of Arkansas Athletic Valley Heating Hot Water Mini-Plant
This project consisted of installing a steam to water converter system to generate heating hot water and extending both chilled and heating water underground to multiple facilities. The heating water generation system was made up of 3 skid mounted converters totaling 41,000,000btu using a steam flow rate of 43,500lb/hr. Converter skid included 3 reservoirs above 3 steam powered condensate pumps capable of removing condensate @ 39,300lb/hr. to a single 425 gallon condensate sump with dual 15hp pumps. Two 50hp vertical in-line heating hot water pumps capable of moving 960 gallon per minute each were installed to handle the pumping of the heating water. Removal of 2 existing chillers and modification to the existing chilled water system was required prior to connection to existing mains. During chilled water modifications a temporary chiller was rented and piped into existing systems to allow continued use of the Indoor Practice Facility for the Razorback Football Program.
The direct bury piping was comprised of 1,160 linear feet of 10” chilled water and 1,160 linear feet of 8” heating water installed under service drive and parking while serving the Indoor Football Practice Facility, the Fred Smith Football Operations Center and capped outlets for future use. The underground system was a mandated, 100% X-Ray on all welded joints, and Mountain Mechanical installed the system with a 100% 1st time X-Ray passing rate.
