Dive Brief:
- EnVerid Systems’ new HVAC load-reduction module brings its sorbent ventilation technology to smaller-tonnage packaged rooftop HVAC systems, helping commercial buildings reduce energy use and costs while maintaining indoor air quality, the company says.
- The HLR 100C fits inside standard roof curbs from major HVAC manufacturers such as Daikin and Trane, easing the process of designing or replacing packaged rooftop units across the range of commercial buildings that use them.
- Each HLR 100C module can offset three to 15 tons of peak cooling load and cut HVAC energy use by up to 40%, the company said in a news release.
Dive Insight:
The HLR 100C uses enVerid’s sorbent ventilation technology to remove harmful contaminants from indoor air, reducing the need for outdoor air ventilation. With less outdoor air intake, buildings can reduce the size of their HVAC equipment to save money and increase energy efficiency as well as the impact of outdoor air pollutants.
Indoor air contaminants of concern — typically generated by building materials, furniture and cleaning supplies — are listed under ASHRAE 62.1.2019. These include aerosol particles less than or equal to 2.5 µm in diameter and chemical compounds and mixtures of compounds like acetone, formaldehyde, xylene and ozone.
The payback period for the HLR 100C, including installation costs, is less than five years and can be immediate, based on climate zone, energy rates, utility incentives and operating hours, the release states.
Daikin Applied Americas has integrated enVerid’s sorbent ventilation technology into its larger packaged rooftop systems and is installing two HLR 100C units into roof curbs at its own design center in Lynnbrook, New York, enVerid said. Jim Macosko, vice president of product marketing and applications at Daikin Applied Americas, said in the release that the easy integration of the HLR 100C into its packaged rooftop systems and air handlers can help the industry “cost-effectively achieve building decarbonization and electrification goals.”
EnVerid notes that the HLR 100C can be used to earn up to six LEED points for optimized energy performance and up to three LEED points for innovation and environmental quality using the U.S. Green Building Council’s pilot credit EQpc165.
EnVerid Systems’ CEO, Christian Weeks, in the release notes a growing need among building owners to tamp down costs and boost the efficiency of their HVAC units. The company has reference designs available for Daikin and Trane and plans to offer more in the future, Weeks said.
