Water source heat pump
The Daikin McQuay SmartSource features high energy efficiency ratings (EER)—up to 22.2 at full load and 29.8 in part load—that exceed ASHRAE 90.1 standards and make the units appropriate for U.S. Green Building Council LEED projects. These settings provide a wider airflow operating range for different applications and duct systems for better comfort. SmartSource water source heat pumps are exceptionally quiet with published sound ratings as low as 46 dBA. Sound reduction packages are available for even greater sound attenuation. Both the vertical and horizontal cabinets have gasket-sealed access panels for lower sound levels and are designed for durability with a rugged, textured powdercoat paint finish. In addition, the compressor is “double isolated” with vibration isolation grommets mounted to a heavy-gauge metal plate, and then isolated from the cabinet base with rubber grommets to minimize vibration.
