Heat Pumps 101
This presentation introduces key concepts surrounding heat pumps, their components, and applications. The session discusses heat pumps as highly efficient systems for both heating and cooling by transferring heat, with a focus on their application in retrofitting multifamily buildings. Topics include various heat pump types—air-to-air, air-to-water, and water-to-water—and their effectiveness based on design considerations, such as refrigerants, system capacity, and equipment selection.
Case studies demonstrate how heat pump water heaters (HPWH) and central heat pump systems improve energy efficiency in residential multifamily buildings, reducing operational costs and greenhouse gas emissions. Additionally, the presentation explores why CO2 is a preferred refrigerant due to its high efficiency and low environmental impact, making heat pumps a critical solution for decarbonization.
