Book Description
This dissertation deals with the experimental and simulative investigation of waste heat recovery from combustion engine exhaust gas in passenger car applications. The focus of the investigations lies on the thermodynamic cycle according to Rankine. The boundary conditions of combustion engines and the limitations of an automobile cause new operating conditions and system operating parameters for Rankine-systems, which will be discussed within this work. The system operating parameters were judged based on their potential to improve the efficiency of a running system, by setting the optimal values for each individual situation. Alternative circuit variants were investigated alongside of the basic configuration, which allowed additional heat input into the system and thereby increase the power output of the Rankine-system. Another operative influence on a waste heat recovery system that was analyzed was the importance of engine operating parameters. This on one hand lays groundwork and on the other hand displays the potentials of different system combinations. The knowledge gained during stationary operation is transferred to dynamic operation in the following. Cold start was chosen as the most important variant of dynamic operation. Results from measurements at starting temperatures down to -10C are presented. These include the first published measurements of temperature and power output for such scenarios. The basics of the behavior of a Rankine-system in cold start are extended by the impact of system operating parameters and circuit configurations. Possible synergies through different kinds of connection from the condenser to the coolant system were investigated as a completing facet of the holistic system view. The target of these investigations was to identify potentials for improvements in the cold start of the automobile by utilizing the heat that is available at the condenser.

Book Description
Heating and Cooling with Ground-Source Heat Pumps in Cold and Moderate Climates: Design Principles, Potential Applications and Case Studies focuses on applications and cases studies of ground-source heat pumps in moderate and cold climates. It details technical aspects (such as materials, thermal fluid carriers and pumping, and drilling/trenching technologies), as well as the most common and uncommon application fields for basic system configurations. The principles of system integrations and applications in moderate and cold climates (such as hybrid, solar-assisted, thermo-syphon, foundation, mines, snow melting, district heating and cooling ground-source heat pump systems, etc.) are also presented, each followed by case studies. Based on the author's more than 30 years of technical experience Discusses ground-source heat pump technologies that can be successfully applied in moderate and cold climates Presents several case studies, including successful energy results, as well as the main lessons learned This work is aimed at designers of HVAC systems, as well as geological, mechanical, and chemical engineers implementing environmentally-friendly heating and cooling technologies for buildings.

Book Description
Heat transfer is the exchange of heat energy between a system and its surrounding environment, which results from a temperature difference and takes place by means of a process of thermal conduction, mechanical convection, or electromagnetic radiation. Advances in Heat Transfer is designed to fill the information gap between regularly scheduled journals and university-level textbooks by providing in-depth review articles over a broader scope than is allowable in either journals or texts.
