Field testing of two prototype air-source integrated heat pumps for net zero energy home (nZEH) application

Integrating multiple functions into a single system offers potential efficiency and cost reduction benefits. Oak Ridge National Laboratory (ORNL) and its partners have designed, developed, and tested two air-source heat pump designs that not only provide space heating and cooling, but also water heating, dehumidification, and ventilation functions. Details on the design, simulated performance, prototype field test, measured performance, and lessons learned are provided.
