Chapman High School - USD 473

 

 

 

 

 

 

Project Description/Scope:

MAWP performed the mechanical and plumbing work for the new Chapman High School in Chapman Kansas. The existing gymnasium was remodeled as part of this project and two 5-ton roof top HVAC units were installed along with exposed double wall spiral duct to serve the existing gym.

The new school was designed using 14 heat pump units ranging in size from 850 CFM to 10,000 CFM located throughout the BLDG. Fresh air was supplied using four energy recovery units ranging from 790 CFM to 3,615 CFM. One 5,466 MBH cooling tower with variable speed fans was located on the roof for heat extraction and included a 760 gallon fiberglass sump tank located in the mechanical room and a plate and frame heat exchanger to separate cooling tower system from the heat pump system. A Dolphin water treatment system was installed on the cooling tower system for water treatment. Hot water was provided by using three 1,060 MBH modulating condensing boilers. A 3,750 CFM kitchen exhaust hood and 3,750 CFM make up air unit was installed for the new kitchen. A Honeywell DDC control system was used for the HVAC system.

The plumbing included a commercial water softener to serve the entire BLDG's domestic water supply. Domestic hot water was provided by eight instantaneous water heaters cascaded together. Low flow fixtures and flush valves were used to minimize water usage.
