The book focuses on design and computational issues related to fixtures and armatures in hydronic heating installations, especially regulation valves, their selection, operating principles, types and construction. The analysis is complemented by connection diagrams, drawings, photos of the valves and computational examples of their selection and operation parameters when used in a pipework and a controlled object, like a radiator. It also discusses issues related to the so-called valve authority, one of the main parameters determining the quality of the valve regulation process. Further, it includes an extensive theoretical framework along with a detailed mathematical analysis and proposes new algorithms, which have been verified and confirmed experimentally. Based on this analysis, the book presents the author's analytical approach for sizing a regulation valve, as well as an innovative design solution for a regulation valve without the limitations of the valves currently available on the market. Lastly, it introduces a new verified method of calculating the valve pre-setting. Intended for engineers dealing with heating issues, scientists and students studying environmental engineering, energetics and related fields, the book is also useful for lecturers, designers, and those operating heating installations, as well as authors of computer programs for thermal and hydraulic balancing of heating installations.

This book addresses key design and computational issues related to radiators in hydronic heating installations. A historical outline is included to highlight the evolution of radiators and heating technologies. Further, the book includes a chapter on thermal comfort, which is the decisive factor in selecting the ideal heating system and radiator type. The majority of the book is devoted to an extensive discussion of the types and kinds of radiators currently in use, and to identifying the reasons for the remarkable diversity of design solutions. The differences between the solutions are also addressed, both in terms of the effects of operation and of the thermal comfort that needs to be ensured. The book then compares the advantages and disadvantages of each solution, as well as its potential applications. A detailed discussion, supported by an extensive theoretical and mathematical analysis, is presented of the computational relations that are used in selecting the radiator type. The dynamics of radiator heat output regulation are also covered, with particular emphasis on underfloor-surface radiators, for which this aspect is particularly important. The book closes with a chapter presenting computational examples. It includes numerous examples of calculations for all essential thermal parameters of radiator operation in heating installations.
