GLASS BOX TO GRAND CASINO SLUDGE. SLIME. ALGAE. BACTERIA. IT’S A JUNGLE IN THERE With Goodway’s new, portable CTV-1500 TowerVac®, cooling tower debris is easily removed without shutting down the unit. An optional filter allows wastewater to be filtered and recycled back into the tower. That means no system downtime and a significant operational cost savings. So lose the hassle, time and environmental mess associated with cleaning your cooling tower — clean it the good way. To find out more, call Goodway today at 800-333-7467, or visit us online at www.goodway.com. ® FIGURE 2. A close-up of the new double façade from the outside. (Photo courtesy of Edgewater Casino.) In the summertime, when solar gains are high, these units assist the natural air movement patterns, from cooler low levels to warmer high levels. As the cooler air moves through the skin, it both removes Input 93 at www.esmagazine.com/instantproductinfo heat trapped within the façade and cools the internal wall before being exhausted at the top of the structure. It thereby eliminates much of the solar gain from penetrating into the occupied space and the effect of the ESM05084Gdwy.indd 1 4/10/08 10:22:53 AM glass absorbing solar energy, warming up, and radiating into the space. Similarly, in the winter, the fans blow hot air up through the double façade to warm the glazing. This removes the negative radiative effect of the cold glass and mitigates the heat loss. The experts in stainless Whenever possible, the air handlers are turned off and all vents steel clean air systems opened to allow for natural ventilation, using the effects of temperature stratification and air pressure differences to naturally draw in intake air for waste water and relieve hot exhaust air. The units can use outdoor air, return air, or treatment facilities, a combination of both — whichever is more effective for the current heating/cooling load. Using outdoor air can be especially effective due to plus: the casino’s location on the bank of Vancouver’s False Creek; the nearby • Custom fabrication water naturally cools the surrounding low-level air. • Rush deliveries DISPLACEMENT COOLING With the varying skin heating and cooling loads effectively handled by A-J Manufacturing offers a complete line of custom the double façade, the remaining challenges for the mechanical system and standard stainless steel air distribution products, all were to provide adequate ventilation and mitigate the internal gains of designed and manufactured to offer durable, dependable the casino.
