Industrial Heat Pumps: Appropriate Placement and Sizing Using the Grand Composite

Show full item recordAbstract
Correct thermodynamic placement of heat pumps
is a necessary condition for optimality. The most
sophisticated equipment designs can do very little to
improve the cost-effectiveness of inappropriately
placed heat pumps. The practice of designing heat
pumps to fit particular unit operations without
regard to the thermodynamic characteristics of the
total process may result in inefficient designs and
is detrimental to the "image" of industrial heat
pumps.
In this paper the heat pump placement is discussed
in the context of the total process. The
process grand composite curve is introduced as a
tool for appropriate placement and sizing of heat
pumps. An example is presented to show that evaluation
of heat pumps in a "stand-alone" sense can
give misleading results.
A procedure for quick preliminary screening of
industrial processes to determine their suitability
for cost-effective heat pump placement is presented.
This procedure can be used to identify heat pump
markets as well as development needs for advanced
heat pumps. As Phase I of a USDOE funded project,
this procedure was applied to several diverse industrial
processes. Some key findings of Phase I of
the project are also reported.
