    2024 AHR Expo: Heat Pumps, Electrification and the Grid

    Jan. 24, 2024
    'Climate change is the HVAC design challenge,'

    "Climate change is the HVAC design challenge," Jon Heller, P.E., president of Ecotope, noted at a Jan. 23 panel discussion at the 2024 AHR Expo in Chicago. Rand Conger, principal at Johnson Barrow, and Sean Jarvie, chief technical officer at Flow Environmental Systems, rounded out the panel.

    "The start of decarbonization began with VRF," Conger said. "Today's hydronic heat pumps [also known as air-to-water heat pumps] require thermal storage. It ensures minimum run times and preserves equipment life."

    Jarvie explained four keys to decarbonize with heat pumps:

    1. No new power feed is needed;
    2. Save space and simplify;
    3. Match existing load conditions; and
    4. Plan for the future.

    "Have a strategy for what's available now and in five years from now," he added.
