Lightweight Radiant Heating and Cooling Systems: Thermal Power and Economic Analysis investigates the technology for installing heating and cooling without wet and dry screeds in a horizontal or vertical arrangement. It presents the determination of comfortable conditions for using LRH/CS and demonstrates how to conduct an economic analysis of available floor heating systems using Multi-Criteria Decision Analysis (MCDA). Representing the first part of an ongoing study, which contains a body of general information about available traditional surface heating systems and systems based on LRH/CS, the book presents laboratory tests, thermal power calculations, and analysis of the comfort of use of a lightweight radiant heating system (LRHS) with and without heat-dissipating lamellas. It also contains calculations of thermal efficiency or maximum supply temperature based on specific materials' parameters for different types of flooring cover, such as ceramic tile. This book is intended for practicing engineers and researchers involved in the design and operation of energy-efficient and sustainable HVAC systems.
