Technology
What are absorption heat pumps?
Absorption heat pumps recover waste heat that is currently lost, such as cooling tower water, flue gases or engine heat, and turn it into useful heat for industrial processes or district heating networks. They run on a lithium bromide and water cycle (LiBr-H2O) with minimal electricity consumption.
Absorsistem offers both Thermax configurations. The Type I heat pump (AHP) uses steam, hot water or exhaust gas as its driving energy to produce hot water up to 95 ºC, with a COP of up to 1.75 and thermal energy savings of up to 35 %. The Type II heat transformer (AHT) runs on waste heat alone and raises its temperature by 30 to 50 ºC, producing hot water or steam at 110 to 160 ºC. Both are built to order for each project.
