Why Is Concrete Cooling Necessary?

Dec 08, 2014 · Companies having concrete work done may have heard the term ‘concrete cooling’ used before. For some people who are unfamiliar with the concrete industry this term may have seemed confusing or surprising. Many people may have been left wondering why concrete cooling was necessary at all.

Concrete Cooling

A method commonly used for concrete cooling is to replace part of the water added to the mix with flake ice. The transition from flake ice to water absorbs a lot of energy and therefore lowers the temperature of the mix significantly. Using flake ice has a much bigger impact on the temperature of the concrete mix, compared to using cold water ...

Freeze Protection of Cooling Tower Basins

Oct 13, 2015 · Abstract. Seasonally shutting down a cooling tower by draining the tower is often not possible for three reasons: (1) In large buildings, the central core must often be cooled, even in sub-freezing weather (2) in sections of the United States, the occasional warm winter day necessitates sporadic air conditioning operation and (3) year-round one or two shift industrial heating loads require ...

What a Water-Cooled HVAC System Can Do for Your Building

Cooling the condenser coil of a chiller plant can be accomplished by air cooling with a finned coil or water cooling with a cooling tower. Water-cooled condensers typically operate at a significantly lower head pressure and use much less energy. A study conducted by San Francisco-based Pacific Gas & Electric Co. (PG&E) showed that, in a typical ...

Radiant Floor Heat Frequently Asked Questions

Like sand, concrete is an ideal carrier of radiant heat because of its inherent thermal mass. As warm water circulates through the tubing (or as electricity warms the heating elements), the concrete flooring turns into an efficient, inconspicuous radiator. Typically, radiant heating systems warm floors to temperatures of 75 to 80 degrees F.
