Abstract

In many industrial thermal processes high grade energy is emitted as waste heat to the atmosphere without being utilized so far. A heat transformer is a device which enables the recovery of these waste heat flows elegantly and profitably. As it raises the temperature level of the recovered heat without thereby consuming considerable quantities of mechanical, electrical or thermal energy, it allows rejection of the recovered heat to the same process. Heat transformers nowadays "on sale" are capable of achieving a maximum output temperature of 150 degrees C, a temperature lift of 50 K and a COP of 0.48. Examples of practical applications and operational experience are given. However, many inquiries from potential customers have shown that temperature lifts to high operating temperatures and better overall COPs are often desirable or demanded. Consequently, a development program ("Advanced Heat Transformer") was started. Advanced heat transformers utilize new working fluids and/or multistage sorption plants including combinations of sorption heat pumps and heat transformers. This paper presents some of these advanced systems and analyzes their possible application.
