context_page_description: An absorption heat transformer is a device which transfers heat from an intermediate temperature level to a high temperature level by means of an absorption process. It is driven by the temperature difference between the intermediate temperature and a low temperature level. The absorption heat transformer splits a heat flow at an intermediate temperature level in two heat flows, at a higher temperature level and at a lower temperature level. Such a device is also denominated type II absorption heat pump or booster heat pump. Absorption heat transformers are especially suitable for heat recovery from industrial processes, its main advantage being the capacity to upgrade to a usable level the temperature of waste heat streams using only negligible quantities of electrical energy and no additional primary energy.
context_section_description: An absorption heat transformer (AHT) is a device which transfers heat from an intermediate temperature level to a high temperature level by means of an absorption process. It is driven by the temperature difference between the intermediate temperature and a low temperature level. The absorption heat transformer splits a heat flow  at an intermediate temperature level  in two heat flows,  at a higher (revaluated) temperature level  and  at a lower temperature level  (rejection heat). Such a device is also denominated type II absorption heat pump or booster heat pump. Absorption heat transformers are especially suitable for heat recovery from industrial processes, its main advantage being the capacity to upgrade to a usable level the temperature of waste heat streams using only negligible quantities of electrical energy and no additional primary energy.
