Air-Source Integrated Heat Pump Research Project
The U.S. Department of Energy is currently conducting research into air-source integrated heat pumps (AS-IHPs).
This project seeks to develop an initial air-source version of an integrated heat pump product suitable for new or existing low-energy residences. The AS-IHP concept is a highly efficient single system designed to meet all the energy service needs for a residence including space-conditioning, dehumidification and ventilation, and water-heating.
Research is being undertaken through a cooperative research and development agreement (CRADA) between the U.S. Department of Energy, Oak Ridge National Laboratory, and a CRADA partner.
The goal of this project is to develop an initial two-capacity AS-IHP product. It is anticipated that this product can provide heating, ventilation, and air conditioning (HVAC) and water heating services to residences at 40 – 45% energy savings versus conventional minimum efficiency equipment.
Benefits and Impacts
Based on the 2011 Buildings Energy Databook estimate for residences using electricity as the primary heating fuel and their estimated total residential HVAC and water heating-related energy use in 2010, if AS-IHP technology penetrates 10% of the HVAC market by 2030, annual energy savings would approach 100 trillion British thermal units.
