Download or read book Heat Pumps for Sustainable Heating and Cooling written by Y. H. Venus Lun and published by Springer Nature. This book was released on 2019-11-13 with total page 137 pages. 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.
Download or read book Heat Pumps for Energy Efficiency and Environmental Progress written by J. Bosma and published by Elsevier. This book was released on 2012-12-02 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 70 papers collected in this volume present an up to date review of the trends in heat pump technology. The heat pump is reviewed both as being part of a more comprehensive system, and as a refined device providing energy and greenhouse gas emission reductions. Its implementation in a system or process must be carefully considered at an early stage of design or development, and process integration is discussed in detail as a valuable tool for industry.The heat pump is proving to be a highly effective energy conserving tool, particularly when designed and used as an integral part of a system. Environmental benefits are gained when energy is conserved, and heat pumps can make a major contribution in this area. However, some heat pumps use working fluids which are environmentally unfriendly, and the progress that has been made in the field of alternative refrigerants is reported on. The volume will prove an indispensable reference source on the wide-ranging applications that have been developed since the last international conference, on such topics as heat pump field trials, pilot plants and development programmes.

Download or read book Research and Development of an Air cycle Heat pump Water Heater Final Report written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A prototype reverse Brayton air cycle heat pump water heater has been designed and built for residential applications. The system consists of a compressor/expander, an air-water heat exchanger, an electric motor, a water circulation pump, a thermostat, and fluid management controls. The prototype development program consisted of a market analysis, design study, and development testing. A potential residential market for the new high-efficiency water heater of approximately 480,000 units/y was identified. The retail and installation cost of this water heater is estimated to be between $500 and $600 which is approximately $300 more than a conventional electric water heater. The average payback per unit is less than 3-1/2 y and the average recurring energy cost savings after the payback period is approximately $105/y at the average seasonal coefficient of performance (COP) of 1.7. As part of the design effort, a thermodynamic parametric analysis was performed on the water heater system. It was determined that to obtain a coefficient of performance of 1.7, the isentropic efficiency of both the compressor and the expander must be at least 85%. The selected mechanical configuration is described. The water heater has a diameter of 25 in. and a height of 73 in. The results of the development testing of the prototype water heater system showed: the electrical motor maximum efficiency of 78%; the compressor isentropic efficiency is 95 to 119% and the volumetric efficiency is approximately 85%; the expander isentropic efficiency is approximately 58% and the volumetric efficiency is 92%; a significant heat transfer loss of approximately 16% occurred in the expander; and the prototype heat pump system COP is 1.26 which is less than the design goal of at least 1.7. Future development work is recommended.
