The papers in this collection have originated from Britain, Eastern and Western Europe and India, with the delegates coming from fifteen countries, including a strong contingent from Japan. This indicates a widespread interest in the application of heat pumps. The heat pump suffers from an environmental dichotomy. On the one hand it saves fossil fuel energy, thereby reducing CO emissions. On the other hand, in the vapour compression form, 2 it generally employs CFCs which are destructive to our protective ozone layer as well as contributing to the greenhouse effect. Taking the first, heat pumps, perhaps have the widest application numerically in the heating (and cooling) of buildings and an excellent paper describes case studies concerning three large Norwegian hotels. In these, heat was pumped from the adjacent river or sea when heating was required, and during the summer, when cooling became necessary, to generate domestic hot water. The heat pumps were installed by SINTEF Refrigeration Engineering, Norway, and have demonstrated payback periods of about two years. The fractional total energy saving of the three hotels was 30% as a result, an impressive figure, indeed. A similar paper by a Belgian architectural consortium shows how this technique can be successfully applied to the cooling of a large television complex where considerable quantities of heat were being generated by the luminaries. In this exercise the cooling load was successfully pumped to provide hot water.

In this collection, the authors evaluate the thermal performance of a ground source heat pump (GSHP) system for cooling a typical household in Tunisia. For this purpose, a complete GSHP system model was built by using TRNSYS simulation program, taking into account the hot climatic conditions of northern Tunisia. The authors also discuss metal organic framework (MOF) material, a new class of adsorbent material that has high surface area, high pore volume, highly tunable structural properties and uniform pore size. Heat powered adsorption heat pumps offer the advantage of using waste heat sources and renewable thermal energy, thus reducing fossil fuel consumption and CO2 emissions. The following chapter presents the major situations where heating and cooling demands could occur simultaneously and be satisfied by heat pumps. The heat pump performance expressed in terms of coefficient of performance and exergy efficiency is then presented for the subcritical vapor-compression thermodynamic cycle. Finally, the integration of such systems in buildings and processes is discussed. Next, the authors seek to demonstrate some antecedents of and technical information on GHPS (Geothermal Heat Pump Systems) on the world, and particulary Mexico. The results of the included study show that sand temperature depends on physical parameters such as grain size, grain shape, quarzt grains amount, moisture content and grain color. The final chapter describes alternative options for heat pump placement indoors and outdoors. The described examples focus on the modelling and measurement of noise levels resulting from heat pumps in the project designing stage and the operation stage.

Download Design of Heat Exchangers for Heat Pump Applications Book in PDF, ePub and Kindle
Heat pumps (HPs) allow for providing heat without direct combustion, in both civil and industrial applications. They are very efficient systems that, by exploiting electrical energy, greatly reduce local environmental pollution and CO2 global emissions. The fact that electricity is a partially renewable resource and because the coefficient of performance (COP) can be as high as four or more, means that HPs can be nearly carbon neutral for a full sustainable future. The proper selection of the heat source and the correct design of the heat exchangers is crucial for attaining high HP efficiencies. Heat exchangers (also in terms of HP control strategies) are hence one of the main elements of HPs, and improving their performance enhances the effectiveness of the whole system. Both the heat transfer and pressure drop have to be taken into account for the correct sizing, especially in the case of mini- and micro-geometries, for which traditional models and correlations can not be applied. New models and measurements are required for best HPs system design, including optimization strategies for energy exploitation, temperature control, and mechanical reliability. Thus, a multidisciplinary approach of the analysis is requested and become the future challenge.

Download Heat Pumps Book in PDF, ePub and Kindle
The text describes the main features of currently available heat pumps, focusing on system operation and interactions with external heat sources. In fact, before choosing a heat pump, several aspects must be assessed in detail: the actual climate of the installation site, the building’s energy requirements, the heating system, the type of operation etc. After discussing the general working principles, the book describes the main components of compression machines – for EHPs, GHPs and CO2 heat pumps. It then addresses absorption heat pumps and provides additional details on the behavior of two-fluid mixtures. The book presents a performance comparison for the different types, helping designers choose the right one for their needs, and discusses the main refrigerants. Notes on helpful additional literature, websites and videos, also concerning relevant European regulations, round out the coverage. This book will be of interest to all engineers and technicians whose work involves heat pumps. It will also benefit students in energy engineering degree programs who want to deepen their understanding of heat pumps.
