Book Synopsis Nordsyn study on air-to-water heat pumps in humid Nordic climate by : Stignor, Caroline Haglund
Download or read book Nordsyn study on air-to-water heat pumps in humid Nordic climate written by Stignor, Caroline Haglund and published by Nordic Council of Ministers. This book was released on 2019-05-03 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study presented in this report has been performed for Nordsyn sponsored by the Nordic Council of Ministers. The aim of this study was to analyse if the information given on the energy labels of air-to-water heat pumps give consumers in Nordic countries sufficient information on energy performance. When comparing results from field measurements to declared values, it shows the declared values are usually better than the field data, especially in countries with humid climate. There could be several reasons for this deviation as non-optimal installations, bypass of control systems, old field data etc. The suspicion that the deviation is due to that the standard tests do not take humidity sufficiently into account could not be proved nor fully dismissed. Recommendations are given on how this could be further investigated, including field measurements in Nordic countries.

This book was released on 2019-05-09 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was performed for Nordsyn sponsored by Nordic Council of Ministers. The aim was to analyse if the energy labels of air-to-air heat pumps give consumers in Nordic countries sufficient information on energy performance, since declared performance was suspected to be higher than in reality. Due to very few field measurements available, this suspicion could not be confirmed nor rejected. It was found that many heat pumps are declared for lower capacities compared to their intended use in the Nordic countries, to obtain a higher SCOP value on the energy label. Market surveillance tests show that it has become rarer that heat pumps defrost during the laboratory tests. Altogether the study shows that the current energy label does not give clear guidance to the consumer. Recommendations for field measurements as well as suggestions for standard and regulation developments are given.

Book Synopsis Alternative test methods, declaration of capacity and test of heat pumps in multiple climates zones: A Nordsyn study on heat pumps in the context of Ecodesign and Energy labelling by : Gustafsson, Ola
Download or read book Alternative test methods, declaration of capacity and test of heat pumps in multiple climates zones: A Nordsyn study on heat pumps in the context of Ecodesign and Energy labelling written by Gustafsson, Ola and published by Nordic Council of Ministers. This book was released on 2021-02-02 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available online: https://pub.norden.org/temanord2020-544/ The objectives of the study are to investigate three aspects concerning heat pumps in the context of ecodesign and energy labelling; potential synergies in testing for more than one climate zone, reduced incentives for low capacity declarations and alternative test methods. A possible alternative to the current test standard is the compensation method, which enables a test that includes the control system of the heat pump. This is closer to real life operation, enables independent market surveillance and provides incentives to develop efficient controls. Experience of using the compensation method for heat pumps for hydronic system are more limited than for air-to-air heat pumps

Book Synopsis Heat Pumps for Sustainable Heating and Cooling by : Y. H. Venus Lun
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.

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.
