Über dieses Buch

This book analyses solar-assisted ground-source heat pump systems, a technology meant for producing heating and cooling energy for buildings. It focuses on ground source heat pump, reversible central heating and cooling system that transfer heat from or to the ground, applications which use solar thermal collectors.

Providing deep insights into energy-saving, solar thermal system operating strategies, it illustrates examples of useful configurations and controlling approach for different climates for different vertical ground heat exchanger depths.

Offering an overview of solar assisted ground source heat pump systems, including design principles and energy-performance data for different climates, it is a valuable resource for designers and scientists who focus on building heating and cooling technologies.

Chapter 1. Ground Source Heat Pump

Abstract

This chapter introduces one of the two main components of solar assisted ground source heat pumps: the ground source heat pump. Main technical aspects have been discussed, explaining the main factors that influence the energy performance and other relevant aspects of great importance for the particular combined application with solar thermal collectors.

Chapter 2. Solar Thermal Collectors

Abstract

Solar thermal collectors are used to heat up a fluid, generally water or a mixture of glycol and water depending of the configuration of the solar thermal system. They are adopted for many applications in both industrial and residential sectors. Many typologies exist in order to comply with heterogeneous needs. All have a common operating principle: to capture solar radiation, converting it to useful heat and transferring it to a working fluid. In this chapter the main solar thermal collector typologies are described giving also information about the application field, system configuration and performances.

Chapter 3. Solar Assisted Ground Source Heat Pump

Abstract

This chapter touches the system configurations of solar assisted ground source heat pumps, giving an overview of the main system components at first. Series and parallel/dual sources configurations have been discussed for a technical point of view, identifying main operating modes in accordance with the use of the produced solar heat. Indicators for assessing energy performance of main system components singularly and overall system have been also presented, paying attention also on the final energy supply chain from the used energy fuels.

Chapter 4. Performance Assessment in Different Climates

Abstract

This chapter analyses performance of solar assisted ground source heat pump system in different climates, drawing suggestions about how to properly configure the system components layout and set operating modes described within Sect. 3.3. Performance of SAGSHPs are logically influenced by the amount of solar collectors installed. Obviously it is not economically and, in most of the cases, even possible to install large solar thermal collector filed. Indeed, residential buildings, both single family houses and block of flat, have limited space for installing solar collectors. Besides amount of solar collectors, V-GHX depth significantly influences SAGSHP, as for conventional GSHP. In addition to these aspects, how operating modes are set and controlled can enormously affect SAGSHP performance. Figure 4.1 shows SAGSHP performance in terms of COP, SPF and SF of studies regarding cold, temperate and mild climates. Overall Fig. 1 in introduction shows that COP and SPF considerably vary in each climate. This chapter aims to critically review main factors responsible of such large range of performance in cold, temperate and mild climates. In order to set properly complete the analyses, solar assisted ground source heat pump applications for hot climate have been also touched.

Chapter 5. Conclusion

Abstract

This chapter summarizes main facts, considerations and design suggestions for solar assisted ground source heat pump applications in different climate presented in this book. Many operating strategy control approaches and system configurations have been presented, extrapolating useful design and operating strategies recommendations for cold, mild and hot climates. A set of energy performance indicators, useful to capture performance of main system components and of the whole system, have been described also. Hopefully, the content of this book serves to bring real and valuable contributions to the market penetration of solar assisted ground source heat pump systems and can somehow contribute to further research and development of this promising heating and cooling system.
