Enhancements stem from more than two years of additional input from engineers, contractors and building owners – resulting in a substantially upgraded, interactive Building Efficiency System Tool™ (BEST).
Available in five models, ranging from 399,000-1 million Btu/hr, the units feature a 97% thermal efficiency, a 10:1 turndown ratio, and an updated heat exchanger.
For new residential and light commercial central air conditioning equipment, the AHRI petition seeks a regulation requiring that equipment manufacturers use refrigerants with a global warming potential (GWP) of 750 or less in equipment made after Jan. 1, 2025, with the exception of variable refrigerant flow (VRF) equipment, whose deadline would be Jan. 1, 2026.
The unit is operated by the new SmartSeries® Plus, a digital touchscreen control capable of running a fully programmable internal schedule as well as connecting to a BACnet building management system.
Building owners and specifiers can experience design flexibility, reduced operational costs, and reliable, energy-efficient comfort year-round with variable refrigerant flow (VRF) systems even in extreme cold climates.
The potential for CARB’s GWP limits and implementation dates to align with the EPA’s sector-based controls under the AIM Act create an environment in which a de facto nationwide HFC regulatory framework could actually emerge.
