Laboratories Best Practices - Minimizing Reheat in Labs

Overview

HVAC systems that are designed without properly accounting for equipment load variation across laboratory spaces in a facility can significantly increase simultaneous heating and cooling, particularly for systems that use zone reheat for temperature control. There are several different HVAC system alternatives that can mitigate reheat energy use.

In this course the student will learn the problem of simultaneous heating and cooling resulting from load variations, and presents several technological and design process strategies to minimize it. The student will also learn about several alternative system types that can minimize or even eliminate the use of reheat energy, including dual-duct-dual-fan systems, fan coil systems, zone cooling and heating coils, and radiant cooling. Continuous commissioning is also discussed as an important tool in minimizing simultaneous heating and cooling.

The student is expected to read and review the material contained in the Laboratories For The 21st Century: Best Practices Guide – Minimizing Reheat Energy Use In Laboratories, August 2005.

The student must take a multiple-choice quiz consisting of ten (10) questions at the end of this course to obtain 1 PDH credit.
