ThermoLift is developing its patented TC-Cycle™ natural gas air conditioner and cold climate heat pump, which combines heating, cooling, and hot water delivery into a single appliance. TC-Cycle™ utilizes an innovative thermodynamic cycle that will result in a 30-50% reduction in building HVAC costs as well as associated reductions in greenhouse gas emissions.
For heating, TC-Cycle™ effectively captures renewable heat energy from the outdoor environment, even at very low temperatures, and delivers it to the building. While for cooling, the natural gas driven TC-Cycle™ uses the captured heat from inside a building to produce hot water, providing essentially free hot water during summer months. Other advantages of TC-Cycle™ include: its compact size, fuel agnostic capability, the elimination of electric compressors and refrigerants for cooling, and service reliability advantages to utilities by shifting energy load from the overburdened electric grid to the under-utilized natural gas network.
Both 1st- and 2nd-generation TC-Cycle prototypes have been built and are undergoing continuous in-house testing. ThermoLift has hosted demonstrations of its Gen 2.0 system with Oak Ridge National Laboratory (ORNL) and National Renewable Energy Laboratory (NREL) representatives at it’s testing facility in Ann Arbor, Michigan. Both prototypes were completed in collaboration with the U.S. Department of Energy (DOE), New York State Energy Research and Development Authority (NYSERDA), and Stony Brook University (SBU). ThermoLift will leverage the knowledge gained during prototype development, along with the expertise of existing partners to improve performance and reduce unit cost for commercialization.
ThermoLift is now working on producing its third-generation prototype and has accumulated over 30 letters of support from domestic and international utilities, research and development partners, and major industry and government entities for the continued development and commercialization of the TC-Cycle™ system.
