ON CALL SERVICES – MULTIPLE PROJECTS

We provided on-call services at Johnson County Community College. This saves JCCC time and money with pre-established fees, and sys-tek is able to respond quickly to the needs of the college.

Child Development Center – Kitchen HVAC Improvements

Under this project, sys-tek was asked to identify the cause of staff overheating in the kitchen when preparing food and to recommend a solution. Upon review of the facility, we discovered a recent expansion to the kitchen as well as the installation of a new kitchen hood. The new hood type was designed to introduce fresh air by using a short cycling hood. Our study indicated that no upgrades were made to the cooling systems serving the kitchen to accommodate the expansion. Additionally, the fresh air, introduced by the new kitchen hood, was not dehumidified which further increased the problem of overheating.

To solve the cooling issues, sys-tek provided a mechanical engineering design to replace the heat pump system serving the kitchen with a larger unit. The design included re-configuration of the ductwork systems to increase airflow specifically adjacent to the kitchen hood. Electrical engineering design included modification to the lighting to accommodate the new airflow design, as well as a larger circuit to support the new heat pump system.

Upon completion of construction, sys-tek will provide testing and balancing of the new systems to ensure they are operating as designed and the kitchen is cooling as desired by the staff.

Art and Technology Building – Ventilation Study

The ventilation systems serving the kiln and furnace rooms of the Art and Technology Building at Johnson County Community College were not operating as necessary to ensure the safety and comfort of students and staff. We were asked to assist in troubleshooting the ventilation systems and make cost-effective recommendations to resolve problems based on field testing, observation, and system review.

Our assessment indicated the existing ventilation system was not strategically located, nor designed to support the use of the space. Daily activities rendered the system incapable of serving fresh air most of the time. Due to the sanding and grinding of pottery, operation of the kiln, and high levels of CO2, a creative solution for heating the space and serving fresh air was crucial.

We provided a detailed report assessing the causes of poor air ventilation, and proposed a cost-effective solution with a design philosophy to ensure fresh air, that is not tainted or cold enough to directly affect the efficiency of the art equipment, be introduced to the rooms.

Other projects have included renovations to classrooms and office spaces, as well as building expansions.
