BrHEAThe and Air Source Heat Pump Integration

Project Purpose: The BrHEAThe system is an integrated heating and ventilation system that CCHRC has been developing for low heat load rural homes. The system has been in development since 2012 and had been installed in many CCHRC designed homes around Alaska. While the installed systems work well and are well received there are potential upgrades to the system that could improve performance. CCHRC and CanmetENERGY are specifically interested in adding an air source heat pump as a secondary heating plant.
Project Abstract: The project will evaluate a new air handler for the BrHEAThe system as well as combining the BrHEAThe boiler with an air source heat pump. The questions for this project are: 1. What is the maximum space heating capacity of the BrHEAThe system based on outside temperature? 2. What is the heat pump COP based on outside temperature? 3. What is the heat pump defrost frequency? 4. What is the DHW capacity of the system?
