Thermally driven heat pumps for heating and cooling

According to the International Energy Agency, 46% of the global final energy demand is attributed to heat and cold. Two thirds thereof are generated from fossil fuels. Both, heating and cooling energy demand is expected to grow rapidly in the next decades. To attain the global goal of CO2 emission reduction energy efficiency must be strongly improved. Thermally driven heat pumps can contribute to reduce the environmental impact of heating and cooling due to their efficient energy use and due to their use of environmentally benign refrigerants with zero Global Warming Potential (GWP). The interest in thermally driven heat pumps and cooling machines is increasing worldwide. This book aims to contribute to improve the understanding of this environmentally friendly technology by providing information about the fundamentals and the recent developments. It is an outcome of Annex 34 Thermally Driven Heat Pumps for Heating and Cooling of the International Energy Agency’s Heat Pump Programme (IEA-HPP) in which experts from about 20 institutions from more than ten countries cooperated. The book is intended for planners, scientists, students and anyone interested, who wants to get an overview of the technology. It comes in form of individual papers of the participating research institutes and companies grouped together in the chapters Thermally driven heat pumps for heating, Thermally driven heat pumps for cooling and, as useful heat and cold can also be supplied simultaneously or seasonally consecutively, Thermally driven heat pumps for heating and cooling. A final chapter deals with Research on working pairs and apparatus technology.
