SEM 04 If You Can't Take the Heat ... Utilizing Heat Recovery Effectively Some applications such as hospitals and hospitality have a constant need of heating energy even during the hottest days of the year and these same facilities often need to run chillers during the coldest days. Engineers often question what chiller technology will most efficiently recover what is otherwise wasted energy. This presentation evaluates how screw and centrifugal chiller technology can best be applied to efficiently recover the rejected energy. The best solution depends on part load performance and chiller piping arrangements.
SEM 05 Free Cooling for Water Source Heat Pump Systems When properly applied, waterside economizers can be a power tool for energy savings in a WSHP system.

With new advances in technology and design strategies, there are many ways to further enhance WSHP system efficiency. This presentation explores some of those efficiency enhancing concepts, such as waterside economizer, enhanced motor technologies, and utilizing DOAS units.
SEM 012 Reheat Strategies for DX Dedicated Outdoor Air Systems As Dedicated Outdoor Air Systems (DOAS) have gained in popularity, many different supply air control methods have arisen. Every one of these methods has something in common; a reheat system. This presentation explores the various types of DOAS reheat systems available, such as Hot Gas Reheat, Liquid Subcooling, and Sealed Refrigerant Loops; and describes how to apply reheat systems for various supply air control methods, such as neutral supply air, space sensible load offset, and space latent load offset.
SEM 047 DOAS and Ventilation Applications This seminar defines the categories of 100% OA equipment used in commercial applications. It covers the three outside design conditions as defined by ASHRAE and how they affect equipment selection. In addition the presentation covers control sequences and application requirements.
SEM 048 High Performance Small VAV Rooftop Systems Engineers are constantly faced with specifying the most efficient HVAC system on buildings of all sizes. This decision becomes tougher on smaller (20K - 50K sq. Ft) buildings where historically they specify systems that they are comfortable with. But this choice may not provide the owner with the most efficient choice. This seminar will explore 4 of the most common systems for these size buildings and how climate zone can impact energy use and the final system selection.

SEM 07 Hydronics and the Effects of Variable Speed Screw Chillers The piping system used on screw chillers has an impact on their performance. This presentation looks at how the chiller plants hydronic system influences screw chiller operation at part load and why a good turn down ratio is important. Changing condenser water temperatures and varying system load represent a significant opportunity for energy savings but the chiller and the piping system must be designed to take advantage of the saving potential.
