This team’s testing and analysis debunked one of the main myths regarding the rate of condensation formation on ACBs and now gives project teams, design engineers, and clients an alternate system solution to evaluate during design.

The most important factor in moisture formation on piping and coil surfaces is the difference between the entering chilled water temperature at the cooling coil and the room dew point. 2020 July. Since water is a denser heat transfer medium than air and can hold 600 times more Btu per pound of heat transfer medium, it requires significantly less volume of water than air to maintain space temperature.
However, the testing demonstrates that condensation formation and water droplet buildup is a very slow process.
Once the length of time is known, we can prove or disprove whether condensation becomes an issue when utilizing ACBs in design. And yes, we have a woman to thank for America's most popular drink.Love them or hate them, mushrooms appear in cuisines worldwide.Walton Goggins of Mulholland Distilling Has a Story to Tell

Chilled beams offer building owners greater energy efficiency, reduced building first cost, reduced day-two maintenance, and improved indoor air quality. The entering water temperature and the calculated room dew point are also listed.
During this time, chilled water was supplied at 58°, or 3° above space dew point, a common ACB design practice to prevent condensation buildup on the beams. Martin has been in the HVAC industry since 2004, working as an energy analyst for Arizona Public Service Energy Services.
Insulating the coil piping supply will expand the window of condensation, allowing controls even more time to respond.Any given project has multiple system options to be evaluated during design. This article will reveal findings from laboratory tests that measured the rate of condensation formation on ACBs when room dew point exceeds the ACB chilled water supply temperature.Team members from SmithGroup Inc., Varitec, and Dadanco collaborated to develop parameters and procedures used to test and understand the length of time a typical ACB forms condensation on the coil. He has been in the HVAC industry for 34 years, beginning in 1985 working as an estimator for Norman S. Wright Co. SW., in the Southwestern U.S.

However, there is a common misunderstanding as to how long it takes for condensation to actually form to a point where it will begin to drip into the space once space dew point rises above an ACB coil’s entering chilled water temperature.Engineers from SmithGroup teamed up with Dadanco, a chilled beam manufacturer, and Varitec, a southwestern manufacturer’s representative, to prove how long it takes condensation to form on beam coils and piping before it becomes a concern for an owner. Two such strategies are either a chilled water temperature reset mode, where chilled water supply temperature is elevated to a level above space dew point, thereby preventing condensation from occurring, or a second option of shutting the chilled water valve at the ACB or ACB zone valve. These are very important facts to consider when ACB systems are a potential project solution.Humidity control strategies can be effectively utilized in ACB systems. A pair of temperature and RH sensors were located at each end of the beam, approximately level with the face of the ACB. McFly are an English pop rock band formed in London in 2003. It took another 3 ½ hours for condensation to form on the finned area of the coil and 18-22 hours before any condensation accumulated enough to fall from the coil.The test results clearly illustrate, should space dew point exceed ACB supply chilled water temperatures, that ACBs can operate at or somewhat below room dew point for longer periods of time than presumed before condensation occurs at a level to be of concern.
