This book introduces two of the most exciting heat pumping technologies,
the coabsorbent and the thermal recovery (mechanical vapor) compression,
characterized by a high potential in primary energy savings and
environmental protection. New cycles with potential applications of
nontruncated, truncated, hybrid truncated, and multi-effect coabsorbent
types are introduced in this work.
Thermal-to-work recovery compression (TWRC) is the first of two
particular methods explored here, including how superheat is converted
into work, which diminishes the compressor work input. In the second
method, thermal-to-thermal recovery compression (TTRC), the superheat is
converted into useful cooling and/or heating, and added to the cycle
output effect via the coabsorbent technology. These and other methods of
discharge gas superheat recovery are analyzed for single-, two-, three-,
and multi-stage compression cooling and heating, ammonia and
ammonia-water cycles, and the effectiveness results are given.
The author presents absorption-related topics, including the
divided-device method for mass and heat transfer analysis, and
truncation as a unique method for a better source-task match. Along with
advanced gax recovery, the first and second principles of COP and exergy
calculation, the ideal point approaching (i.p.a.) effect and the
two-point theory of mass and heat transfer, the book also addresses the
new wording of the Laplace equation, the Marangoni effect true
explanation, and the new mass and heat exchangers based on this effect.
The work goes on to explore coabsorbent separate and combined cooling,
heating, and power (CHP) production and advanced water-lithium bromide
cycle air-conditioning, as well as analyzing high-efficiency
ammonia-water heat-driven heating and industrial low-temperature
cooling, in detail.
Readers will learn how coabsorbent technology is based on classic
absorption, but is more general. It is capable of offering effective
solutions for all cooling and heating applications (industry,
agriculture, district, household, etc.), provided that two supplying
heat-sink sources with temperatures outdistanced by a minimum of 12-15°C
are available. This book has clear and concise presentation and
illustrates the theory and applications with diagrams, tables, and
flowcharts.
