Central Valley Research Homes: Evaluation of Ducted and Ductless Configurations of Variable Capacity Heat Pumps

This report covers the work done during spring 2016 through winter 2017 as a continuation of the Central Valley Research Homes project which began in 2012. This phase of the project evaluated the installed performance of variable capacity heat pump (VCHP) systems in three (3) California research homes in Stockton, California. The project was a direct comparison of ducted and ductless VCHP systems serving the same house, with both VCHP systems also compared to a standard single speed forced air heat pump system that was monitored in the same house during the prior year. The two primary evaluation topics were energy performance and comfort.
