R&D of lithium bromide absorption heat transformer.

Author(s) : WANG C., ZHEN L.

Summary

The Lithium Bromide Absorption Heat Transformer (LBAHT) can upgrade the temperature of waste heat with little electricity. It can be used as an alternative technology to CFCs due to its working pair— lithium bromide and water doing no harm to the ozone layer of the atmosphere.The LBAHT is powered by waste heat. Part of the waste heat whose temperature is upgraded will be reused iq industrial processes, and other part will be rejected to low temperature heat sink. Hot water is supplied from absorber or steam is supplied from steam flasher. There is much more waste heat in some solvent products factory. After investigation in the factory, we decided to adopt the LBAHT to reduce the consumption of the initial energy source and to raise the energy efficiency. Before its designing, according to the practical situation of the solvent factory, three design schemes have been worked out. In the paper, the flowlines, COP, and performance on changed working conditions are described and analyzed. With comparison , we find that it is possible to make use of the LBAHT in the solvent production to recover waste heat. Its economy is rather good.
