Great paper by Thomas Manjarres and Allen Dusault of Franklin Energy highlighting the important difference between site energy efficiency and actual carbon emission reduction. Specifically, this paper shows that replacing gas space heating equipment with electric heat pumps in cool climate zones will actually increase carbon emissions, in addition to increasing the home owner’s utility […]
In March 2019, two of SMTI’s 80,000 BTU/hr Gas Absorption Heat Pump prototypes were commissioned at restaurants in Southern California as demonstration projects. They will provide both DHW heating and supplemental cooling to the full-service restaurants, cutting hot-water heating bills by up to 50%, plus the additional free-cooling benefit. Project economics of 1-3 year paybacks […]
SMTI recently achieved a 1.41 COP (coefficient of performance) at design conditions for our “Beta” 140,000 Btu/hr GAHP model. The commercial-sized (for water and space heating) prototype was developed by SMTI in cooperation with Oak Ridge National Lab and an OEM partner. Testing at ORNL in October was below original target (COP of 1.35), which […]
