In many climates buildings are unable to provide comfort conditions for year-round occupancy without the benefit of a heating system, and most HVAC engineers will routinely be involved with issues concerning the design, installation and performance of such systems. Furthermore, in temperate climates, heating of buildings accounts for a large slice of annual carbon emissions. The design of heating systems for maximum efficiency and minimum carbon emission is therefore now a matter of prime concern to all HVAC engineers. The book provides an up-to-date review of the design, engineering and control of modern heating systems. Part A deals with heat generating plant. While this concentrates on conventional and condensing boilers, small-scale combined heat and power systems and heat pumps are also discussed. Part B deals with heat emitters, pipe circuits and variable-speed pumping, hot water service, optimum plant size and the vital issues of plant and system control, including sequence control of multiple boilers. Techniques for managing the energy use and running costs of heating systems are also discussed. The authors have brought together over a half-century of combined experience covering all aspects of the building services Industry to provide an up-to-date and comprehensive text that is both technically rigorous yet highly practical. This makes the book equally relevant to the busy HVAC engineer looking for a handy practical reference, the student looking to build on their basic knowledge or the researcher interested in key issues of heating system design and performance.

Combustion is very much an interdisciplinary topic, drawing together elements of chemistry, fluid mechanics and heat transfer. It is an ingredient in many undergraduate degree programmes, ranging from a pivotal role in fuel science through to a component part of courses in chemical, process and building services engineering. For many students in those disciplines where combustion in heating plant is an important part of their studies, there are often problems in coming to grips with the basic principles underlying the combustion of hydrocarbon fuels. In particular, the concepts of chemical and related thermodynamic changes can prove difficult to assimilate. The scientific literature dealing with combustion tends to be rather polarised, with a wealth of literature aimed at the specialist reader, but at a basic level the fundamentals of this important process are often treated rather tersely in textbooks on thermodynamics. The objective of this book is to provide an introduction to the basic principles of the combustion of hydrocarbon fuels in heating plant for buildings and industrial processes. In those chapters where practice in problem solving can make a positive contribution to understanding, some numerical problems have been included. Acknowledging the ever-widening use of computers in technical education, a number of algorithms which can be easily coded up for solving numerical problems have been incorporated in the text. These can prove particularly useful in, for example, the calculation of certain fluid properties, either for use in hand calculation or for incorporation into larger programs.

Control Systems for Heating, Ventilating and Air Conditioning, Sixth Edition is complete and covers both hardware control systems and modern control technology. The material is presented without bias and without prejudice toward particular hardware or software. Readers with an engineering degree will be reminded of the psychrometric processes associated with heating and air conditioning as they learn of the various controls schemes used in the variety of heating and air conditioning system types they will encountered in the field. Maintenance technicians will also find the book useful because it describes various control hardware and control strategies that were used in the past and are prevalent in most existing heating and air conditioning systems. Designers of new systems will find the fundamentals described in this book to be a useful starting point, and they will also benefit from descriptions of new digital technologies and energy management systems. This technology is found in modern building HVAC system designs.

Heating Services Design focuses on the design of heating systems. The book first discusses the fundamentals of fluid flow. Topics include fluid properties, viscous fluids in motion, fluid flow in pipes, and additional losses in pipes. The text explains automatic control and considers feedforward and feedback control, process reaction rate, system time lags, control valves, modes of control, and cascade and multi-controller systems. The book also discusses heating system design; estimation of the heating system load and energy consumption; and steady-state heat losses. The text describes heat emission and emitter selection. Heat emission from pipes, plane surfaces, radiators, and convectors; emitter arrangements; and partial load conditions are underscored. The selection also explains water heating systems. Topics include system layouts; design flow rate and apportioning of the mains emission; sizing the pipework; domestic forms of low pressure of hot water heating systems; pressurized heating systems; and group and district heating. The text is a good source of information for readers interested in the design of heating systems.

This 'Non-Domestic Heating, Cooling and Ventilation Compliance Guide' provides guidance on the means of complying with the requirements of Part L for conventional space heating systems, hot water systems, cooling and ventilation systems in non-domestic buildings. Its sets out the minimum provisions for: efficiency of the plant that generates heat, hot water or cooling; controls to ensure that the system is not generating heat, hot water or cooling unnecessarily or excessively;other factors affecting the safety or energy efficiency of the system; insulation of pipes and ducts serving space heating, hot water and cooling systems; and acceptable specific fan power ratings for fans serving air distribution systems. The guide also provides a set of additional measures which may improve the efficiency of the plant: these are non-prescriptive may be either required or optional depending on the type of plant.

Residential space and water heating accounts for 23% of UK final energy demand and combination gas boilers are the dominant technology. Performance gap issues in gas boiler systems have been reported, with previous studies unable to isolate or quantify root causes for performance issues. Dynamic behaviour of boiler heating systems is important to their overall performance, issues of plant size, supply temperature regulation and system control effect the performance of the system. The UK Standard Assessment Procedure (SAP), contains simplifications to aid ease of use and comparability of resulting Energy Performance Certificates (EPC) but they partly overlook these key dynamic issues. Three complementary methods were used to analyse heating system dynamics; a cross-model comparison, real world data from four case studies and a statistical analysis of a 217 boilers sample. Comparing SAP with a dynamically modelled system, showed that SAP results correspond closely to a model using an idealistic heating system, with perfect control and instant responsiveness. Introduction of a physically realistic gas fired boiler and water-based heating system to the model results in a consistent increase in internal temperature (0.5°C) and energy demand (ca. 1000 kWh/a). Variation of controls and plant size show an efficiency penalty for oversized boilers with limited modulation and poor thermostat controls. The key issue of boiler cycling was highlighted as a dynamic symptom of poor efficiency performance. From in situ analysis of boilers, cycling behaviour was observed indicating widespread performance reduction, as was seen in simulation. Most observed combi-boilers appear oversized for space heating and despite available modulation are unable to prevent rapid on-off cycling. Per day, half of combi boilers studied average more than 50 starts and 70% of cycles average less than 10 minutes during space heating operation. Boiler dynamic performance is not reflected in UK and EU efficiency testing standards, which assume steady state operation. The characterisation of the dynamics of gas boilers highlights issues of oversizing and excessive cycling, and reveals opportunities to improve the current building stock energy demand/emissions through better installations, EPCs, and energy labelling.
