Developing a Standard Method of Test for Integrated Heat Pumps Research Project
The U.S. Department of Energy is currently conducting research into the development of standard Method of Test (MOT) for integrated heat pumps (IHPs). No active, recognized test procedure or rating standard exists for IHPs. Generating a rating standard with supporting test procedure that is approved by the American Society of Heating, Refrigerating, and Air Conditioning (ASHRAE) and the Air Conditioning, Heating, and Refrigeration Institute (AHRI) is necessary for these products to be viably marketed. The primary market segment for IHPs is residential buildings, both single-family and small, low-rise multifamily dwellings.
This project seeks to develop a test procedure for integrated heat pumps and to drive the process to produce the needed standard forward.
This project is being undertaken between the Department of Energy and Oak Ridge National Laboratory.
The first goal of this project is to develop an ASHRAE standard for a method of test for IHPs. The second goal is to develop an AHRI rating standard for IHPs.
Benefits and Impacts
Based on the 2011 Buildings Energy Databook estimates of residences that use electricity as the primary heating fuel, and the estimated total residential heating, ventilation, and air conditioning and water heater energy use in 2010, if the IHP technology penetrates 10% of that market by 2030 it is extrapolated that annual energy savings would approach 100 trillion British thermal units.
