The book begins with an introduction to the engineering systems in a hotel and goes on to discuss the fundamental concepts of work, power, and energy. It also touches upon basic electrical wiring and safety precautions with respect to electrical appliances in a hotel. Further, it elaborates the science of illumination and lighting requirements for different functional areas in a hotel. Topics such as fire and its prevention, water hardness and its treatment, water distribution systems, refrigeration, ventilation and air conditioning are also elucidated. The book discusses maintenance requirements of buildings, utility systems, and also the safety and security of a hotel. Owing to its coverage of key concepts of engineering in the context of the hospitality industry, the book would also be useful for practising hotel engineers.
