Heat transformer with self-circulation: report from pilot plant experiments.

Author(s) : ABRAHAMSSON K., JERNQVIST A.

Summary

An ideal heat transformer works at three temperature levels and two pressure levels. The heat input to the generator and evaporator is at a middle temperature level, while heat is produced at a high temperature in the absorber and dissipated at a low temperature in the condenser. The evaporator and absorber are at a high pressure level while the generator and condenser are at a low pressure level. Besides those four main components, the apparatus usually includes one heat exchanger and two pumps, the latter being electrically driven. The authors describe a heat tranformer with self-induced circulation using the static pressure difference. The tested pilot plant is constructed to maintain a pressure difference of approximately 1 bar with the working pair water-caustic soda. Certain results are given. The COP of the pilot plant is very low and with the present configuration it seems impossible to have a higher COP value than 0.13.
