Adsorbent heat pump. Demonstration of a thermally powered adsorption heat pump, which has an adsorption heat exchanger that uses heat at temperatures from 60 degrees Celsius as its driving energy instead of electricity. Due to their low energy consumption, adsorption heat pumps achieve a much higher cooling or heat output in relation to the wattage used than conventional heat pumps. Researchers from IBM Research and other institutes operate a project called THRIVE (Thermally Driven Heat Pumps for Substitution of Electricity and Fossil Fuels). The research focuses on adsorption heat pump (AdHP) technology, which relies on the use of adsorbent materials. Image published in March 2015.
