CO2 Heat Pump Water Heater
Overview
Project Objectives: The Washington State University (WSU) Energy Program conducted research on two types of combined space and water heat pumps in field and controlled experiments in existing homes of various efficiencies and climates. One technology uses CO2 refrigerant and will be tested for performance at six field sites and at the PNNL Lab Homes for efficiency and demand response (DR) capability. Costs of system installation and energy use will be collected and analyzed. In as many cases as possible, monitoring will be installed prior to installation in order to establish a baseline.
Current Project Phase: Completed
Current Project Status: The final report for TIP 338 was delivered, however some of the goals of the research could not be met because of inadequate cold weather data.  Data collection was delayed duethat only allowed for very limited data in the heating season. WSU has continued to collect data from the monitoring which was left in place, BPA funded project 3 to analyze the data results . The final report is being edited and will be posted Q1 of FY20.
