The FSEC Energy Research Center(FSEC) at the University of Central Florida has investigated low-cost space-conditioning upgrade solutions for existing homes since 2014. The retrofits involve installing a modest capacity, centrally located, high efficiency, ductless, minisplit heat pump (MSHP) for use in conjunction with the home’s existing central space conditioning system (CSCS). This type of retrofit targets homes with older but not obsolete CSCSs that have not reached end of life, and presents a more cost-effective option to achieve space conditioning energy savings than outright CSCS replacement. This report describes results from investigating the energy savings potential, given adherence to comfort management, if the control of the MSHP and CSCS were integrated.
