Performing a minor modification, at this NewYork-Presbyterian Hospital facility, to the chilled-water system control sequence resulted in an immediate demand reduction of 650 kW.
A change in the control sequence at South Nassau Communities Hospital increased the chilled-water return temperature from 47 F to 52 F, doubling the chilled-water delta T.
Improvements at the Pennsylvania State Capitol Complex have increased the chilled-water delta T from an old range of between 6 F and 7 F to a new range between 12 F and 19 F.
New control logic on an air handler at Bristol-Myers Squibb resulted in an average 89 percent improvement in chilled-water delta T compared to an identical air handler using the old control logic.
