MODULATING gas-fired infrared heaters . . .for manufacturing, warehouses, loading docks, autobody repair shops, and more! CaseInPoint to serve the year-round cooling load of up to 175 tons for the top two ﬂoors. A 100-ton unit provides year-round cooling to the top ﬂoor and a 75-ton unit serves the second ﬂoor. Both units are controlled by MicroTech® II controls with McQuay’s Open Choices™ feature, which simpliﬁed integration into the Andover BAS. Titus VAV boxes with Fulton hot water boilers provide zone control and heat the building. A McQuay Vision™ AHU, an exterior 60-ton condensing unit, and two 50-ton rooftop units serve the ﬁrst-ﬂoor spaces. Aerosonics provided the duct silencers. “The McQuay units give us the performance we need for acoustic reverberation and radiated sound,” said Dawson. “Discharge sound is mainly attributed to the fan of a unit, so we chose plenum fans and wheels because they’re much quieter than other fan conﬁgurations. “The ﬂexibility to choose the fans and wheels we required helped us meet the NC requirements. And we were able to cut down on vibration and radiated sound because these units are built so solidly.” To provide further soundprooﬁng, the ceiling of each of the top-ﬂoor studios is resiliently suspended from the roof to avoid any vibration transmission from the rooftop equipment. “Not only did we need a quiet system, we also needed a reliable one,” said Dawson. “HVAC systems in studios are important not just for the people who work there, but also for the broadcast equipment, which must operate 24 hours a day.” Kansas City listeners would be reassured to know that even the HVAC system has a role in keeping news, music, and sports coming through loud and clear without a hint of background distraction.
