Book Synopsis Applications and Efficiency of Heat Pump Systems by : Ian E. Smith
Download or read book Applications and Efficiency of Heat Pump Systems written by Ian E. Smith and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Book Synopsis Design of Heat Exchangers for Heat Pump Applications by : Marco Fossa
Download or read book Design of Heat Exchangers for Heat Pump Applications written by Marco Fossa and published by MDPI. This book was released on 2020-12-28 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the significance of using sustainable energy to prevent the deterioration of our planet using heat pumps. Energy sustainability can be achieved through improved energy efficiency. In this regard, heat pumps offer an energy-efficient alternative for heating and cooling. To drive the adoption of heat pumps as a key component of sustainable buildings, the authors focus on examining sustainable practices in heat pump operations and innovative system design. In view of the growing desire to use sustainable energy to meet heating and cooling demands and improve indoor air quality, this book offers a valuable reference guide to the available options in HVAC (heating, ventilation, and air-conditioning) system design. To begin with, the authors define sustainable energy and discuss the trend of “thinking green” in building design. They then discuss sustainable practices and heat pump applications in mapping out HVAC systems. In turn, they examine the use of green operations to promote sustainable practices and, in order to highlight the importance of innovative design, discuss the configuration options and precision control aspects. In closing, the authors illustrate innovative sustainable design on the basis of several energy-efficient cases. The book’s main goal is to drive the adoption of sustainable energy solutions. Heat pumps, it argues, represent the most efficient system for meeting commercial/recreational/residential heating and cooling demands. The book not only examines industrial practices in heat pump application, but also discusses advanced heat pump technologies and innovative heat pump designs.
