Humidification Retrofits Deliver Residential Furnace Efficiency, 12/14, 1:00 - 2:00 PM CST, Webinar
Event Description

Standard efficiency furnaces are robust, long-lived appliances — but they use 15% more natural gas than the current best available technology, and they are still being installed frequently today. They are seldom replaced by high-efficiency units before the point of failure, which implies hundreds of trillions of BTUs in missed energy savings over the next few decades.

To find a new way to increase the efficiency of standard furnaces, researchers looked at transport membrane humidifier (TMH) technology, which can retrofit the standard older furnaces to make them as or more efficient than new furnaces. TMHs transfer waste heat and water vapor from flue gases into the building air supply. This improves efficiency and occupant comfort by adding humidity to dry winter air. The study tested TMH technology in four cold-climate sites to assess the lifetime energy savings potential for the state of Minnesota.

Join us for a technical overview of the field assessment, measured energy savings, occupant feedback, and evaluation of cost-effectiveness of transport membrane humidifier (TMH) technology.

    • Josh Quinnell, Ph. D.
      Senior Research Engineer | Center for Energy and Environment

      Josh has 12 years research experience in solar energy, heat and mass transfer, and renewable technology development. For the last three years, Josh has worked on building energy efficiency projects including commercial and institutional HVAC duct leakage, condensing boiler efficiency monitoring, optimization of energy recovery ventilation (ERV) systems, residential garage contaminant transport, and transport membrane humidifier technology (TMH). Josh is also part of Solar Pathways, a project to identify optimal scenarios that meet the Minnesota’s solar goals.

      Prior to CEE, Josh spent time at ZAE Bayern in Munich, Germany, researching thermochemical energy storage cycles for solar and district energy applications. Josh obtained his master’s degree (2008) and Ph.D. (2012) in Mechanical Engineering from the University of Minnesota.
