Chilled water systems are pretty common, especially in bigger buildings, and especially institutional/commercial buildings.


I worked on the control system for a "Green" LEED platinum residential development here in Victoria. Every summer, without fail I get a call from some of the residents: "I've set my thermostat for 15 degrees and It's not coming down, it's 30 degrees in here".

"Yes maam, your building doesn't have COOLING, please open a window"
That's interesting to hear that. Our developer made a big point of not calling it "A/C" but called it "cooling" to lower people's expectations. The main difference they explained is that A/C runs on a refrigerant and gives instant cold air on demand, whenever you want. Even in the middle of winter.

Ours only works on hot days when the chilled water is fed through and the more overall demand on it, the better it performs.

I will say it's definitely not as cold as say the A/C in our car. And it works better on a hotter day when more people are using it. But for the most part it does take the edge off and keeps the interior temp from spiraling out of control on a hot day. We slept great each night during the heat wave.
