Expanded to include 7-, 10-, 13-, and 15-ton size B-cabinet models, the Atherion® commercial packaged ventilation line is designed to meet ASHRAE 189.1 and 62.1 standards for IEER efficiency and IAQ.
Available in 3-5 ton gas/electric, electric/electric, and heat pump models, the Z-Series™ commercial rooftop packaged units fit many of today’s most common curb sizes.
Two NuTone packaged systems — heat pumps and packaged gas/electric models — include all-aluminum microchannel coils for lighter weight, smaller size, better durability, and greater reliability in corrosive environments, said the company.
The York® line of Affinity™ packaged heat pumps has been expanded with the addition of the 2-, 2.5-, 3-, 3.5-, 4-, and 5-ton dual-fuel packaged heat pumps. They achieve efficiencies up to 14 SEER, 11.8 EER, and 8 HPSF, delivering energy savings and comfort.
Packaged air conditioning solutions from Trane now feature a more rugged microchannel aluminum coil construction to increase reliability and sustainability. The more robust microchannel coil replaces copper and aluminum tube-and-fin condenser coils. The microchannel coils reduce refrigerant charge as much as 50 percent.
U.S. commercial building owners could save an average of 38 percent on their heating and cooling bills if they installed a handful of controls to make their HVAC systems more energy efficient, according to a recent report.
Pacific Northwest National Laboratory (PNNL) announced that it has evaluated a number of control strategies that can be implemented in a controller, which can be retrofitted into an existing unit, to substantially improve the operational efficiency of commercial packaged equipment.
The York® brand of products with MagnaDRY™ technology has been expanded to include 3-5-ton Predator MagnaDRY hot gas reheat packaged units. The ZR037, ZR049, and ZR061 are based on a state-of-the-art dehumidification system that keeps occupants comfortable in humidity-sensitive applications without overcooling the space.
