Heat Pump for ACs

Energy Savings and Modernization of Single-Family Cooling Systems Goal


Air source heat pump (ASHP) systems are not yet cost competitive with the dominant heating residential system in Minnesota, the natural gas furnace. ASHPs also face integration challenges with existing furnaces. Manufacturers are adapting to this reality by developing new ASHP equipment to better integrate with existing systems rather than displace them.

This study will examine ASHPs as direct air conditioning (AC) replacements with no changes to the furnace, or for joint replacement with the furnace when both are needed. Using ASHPs to replace AC will provide increased cooling savings and help grow cost-effective market channels to increase familiarity and acceptance of modern HVAC technology among customers and practitioners to better prepare Minnesota households for a changing energy landscape.

Project Summary


This project will use characterization and modeling efforts to examine an emerging market product category of interest to manufacturers — air source heat pumps that are designed and marketed as AC replacements.
