Heat-Of-Reaction Chemical Heat Pumps--Possible Configurations
Abstract
Chemical heat pumps utilize working fluids which
undergo reversible chemical changes. Mechanically
driven reactive heat pump cycles or, alternatively,
heat driven heat pumps in which either heat engine
or heat pump working fluid is reactive, are considered. As such, chemical heat pumps can be classified
by (a) drive (electric drive, waste heat drive, or
prime energy drive), (b) operating mode (periodic or
continuous), (c) type of coupling between the heat
engine and heat pump, (d) thermodynamic cycle used
in the heat engine and heat pump, and (e) phases of
the working material. This matrix classification of
chemical heat pumps illustrates that there are many
possible chemical heat pumps, suggests new heat pump
configurations which have not been previously considered, and reveals that systematic evaluation of
these configurations is possible. Dimensions of the
heat pump matrix are described, and heat pumps examples
are discussed. Configurations selected for
initial study in DOE's industrial heat pump program
are highlighted.
