The April 2012 chapter meeting will be held at LUNCH time on Monday, April 9th, 2012.
Main Program at 12:00 P.M. (PLEASE NOTE TIME CHANGE)
Sustainable Chilled Water Systems
This presentation will explore several different chilled water system choices and some benefits of shifting peak load of the HVAC system to save energy costs. Producing and storing ice at night, when energy costs are lowest, and discharging cooling during the high on-peak rate period, reduces demand charges and can lower peak power usage.
We will discuss the application of different types of chillers circulating a cold glycol/water solution through dedicated ice tanks. During the on peak discharge cycle the glycol/water solution is piped through the tanks. The cooled solution is then circulated to satisfy the building cooling load.
Carefully applied, demand charges and energy costs can be reduced.
Sustainable designs and high performance standards such as ASHRAE Standard 189 will be discussed.
