Variable Capacity Heat Pump Technology Roadmap

Abstract
The Variable Capacity Heat Pump Measure Development Roadmap is one of the first outcomes of a structured process to identify research and development needs for emerging, energy-efficient technologies in the Pacific Northwest. This Roadmap is essentially a snapshot of stakeholders' current perspectives in regard to a shared research agenda for the next twenty years. Supported by the Portland State University Department of Engineering and Technology Management and the Washington State University Extension Energy Program, 35 experts from 20 organizations have participated to date. The roadmap is a living document that is continuously refined with new knowledge. It is intended as a living document, continuously refined as we move forward.

In support of BPA's Technology Innovation initiative, Electric Power Research Institute (EPRI) will design and construct a test stand with five climate chambers. This test stand will be used to gather data on performance of three advanced heat pump systems with variable refrigerant flow and heat recovery capability (VRF HR). Performance maps for these three VRF HR systems will be used to improve modeling software for simulation of building energy use. This project helps address gaps for Variable Refrigerant Flow systems identified in the National Energy Efficiency Technology Roadmap Portfolio.

Measure Summary Report for Variable Capacity Heat Pumps

Abstract
BPA contracted EES Consulting of Kirkland, Washington to perform secondary research and provide estimates of efficiency improvements through the application of variable capacity heat pump technology in the Northwest. The report summarizes a set of technical options of interest efficiency programs in the Pacific Northwest. EES estimates five average megawatts of electricity could be saved by heating and cooling buildings in the Pacific Northwest with variable capacity heat pumps.
