The use of solar collectors for domestic hot water over the past 20 years has demonstrated that solar heating systems are now founded on a reliable and mature technology. However, the development of similar, but more complex, systems to provide both domestic hot water and space heating (solar combisystems) resulted in a diverse range of different designs that were not carefully optimized to reflect local climate and practice. Application of energy-efficient building strategies such as improved thermal insulation and use of low temperature heat supply systems is becoming increasingly common. This trend, combined with growing environmental awareness and the subsidies available in certain countries, favours an increase in market share for solar combisystems. The need for guidelines in selecting the appropriate system and designing this system according to the specific needs of the building and the local environment is therefore now increasingly pressing. This book fills that need.
The 4th edition of Plumbing continues to provide the definitive single volume text on plumbing, heating and gas installation work, ideal for students working towards their Diploma in plumbing or NVQ/SVQ at levels 2 and 3. Highly illustrated and easy to read and understand, it tackles plumbing topic by topic, in double page spreads with text, full colour illustrations, and clear photographs, enabling the reader to grasp the essentials quickly and easily. This approach ensures it also provides a concise reference for the trained plumber. Special features include: concise text many clear, full colour illustrations around 140 photographs topics focussed on the needs of NVQ/SVQ levels 2 and 3 add...
It has long been recognised that thermal technologies must ensure the safety of food without compromising food quality.
What is heat treatment? This book describes heat treating technology in clear, concise, and nontheoretical language. It is an excellent introduction and guide for design and manufacturing engineers, technicians, students, and others who need to understand why heat treatment is specified and how different processes are used to obtain desired properties. The new Second Edition has been extensively updated and revised by Jon. L. Dossett, who has more than forty years of experience in theat treating operations and management. The update adds important information about new processes and process control techniques that have been developed or refined in recent years. Helpfull appendices have been added on decarburization of steels, boost/diffues cycles for carburizing, and process verification.
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.
Offers details on the utilization of electrical heating elements in consumer appliance design and industrial processes. The text includes basic theory, metallurgy and production advice for developing more reliable and cost-effective heaters. It provides tables comparing resistivity and surface resistance of different materials, and listing the resistance and weight per metre as well as surface per ohm of whole and half B&S wire and ribbon sizes for common standard resistance heating alloys. The book also contains calculation equations suitable for use in BASIC programs.
