SWEAT thermochemical heat pump storage system.

Author(s) : BEIJER H. A. de, KLEIN-HORSMAN J. W.

Summary

The great potential of chemical heat pumps for storage and transformation of thermal energy becomes more and more obvious. The SWEAT (Salt Water Energy Accumulation and Transformation) system, has led to a new heating and cooling system. The system can best be described as a thermochemical heat storage system which stores low temperature heat from solar systems, district heating systems and waste heat from industrial processes or car motors. At a later stage heat or cold can be produced by using the thermochemical heat pump function. The basic problems with comparable systems in the past were: poor stability and side reactions of the materials used, low power output, low efficiency. Research done by the authors in cooperation with the Delft University in the Netherlands and some industrial companies improved the system considerably, and this eventually led to the development of a tube like heat pump module. The article describes a number of improvements and some prototypes built for special applications.
