Lab Test for Short Run Ducted MiniSplits for Residential Applications

Ducted mini-splits are currently available for single family applications. Research is required to determine if these units will be more efficient than the traditional ductless heat pumps DHPs with back up resistance heating. This research project will utilize the Pacific Northwest National Laboratory (PNNL) Lab Homes to test how the performance of a multi-zone ducted mini split application compares to the traditional single zone DHP with back up resistance heat in a single family application. The PNNL Lab homes provide the opportunity to conduct a side by side experiment with identical homes. Results of this research will determine if BPA should pursue additional field tests.
