The HVAC systems are designed for peak conditions. Because these conditions prevail only for small period in a year, the HVAC equipment must operate most of the time at lean capacity. The function of the control system is to adjust the equipment capacity to match the load. Automatic controls are necessary not only to achieve the design conditions in the conditioned space but are also required for efficient operation of the HVAC system. The main parameters to be controlled in air conditioning system are temperature, pressure, humidity, air quality and thermal energy distribution. This 6 -hour quick book covers the basic control fundamentals of automatic controls in the HVAC system. Emphasis is placed on the control principles, terminology, basic components, control devices and direct digital control systems. Numerous illustrations and examples have been included to enhance the understanding of the course material. This course is aimed at the personnel who have some limited background in the air conditioning field or who may be having difficulty relating controls to air-conditioning equipment. The course is suitable for students, mechanical, electrical, controls and HVAC engineers, architects, building designers, contractors, estimators, energy auditors and facility managers.The book includes a multiple type quiz (30 questions) at the end.Learning ObjectiveAt the conclusion of this course, the student should be able to: * Define the basic blocks of control system;* Distinguish between open loop and closed loop systems;* Describe different types of temperature, humidity, pressure and flow sensors;* Define setpoint, control point, offset and throttling range;* Determine controller action for given the application;* Distinguish between direct and reverse reset;* Distinguish between the mixing and diverting valves;* Define flow coefficient, valve authority, controllability, rangeability and turndown ratio; * Describe the sizing of control valves;* Define proportional control, PI control and PID control;* Describe direct digital control terminology, hardware and control network;* Cite the energy saving benefits of DDC systems.

This book offers the latest technology on HVAC Controls. While most industrial controls have benefited from advances in personal computer control and sensor technology, building controls have lagged behind. Only now are some of the techniques used in industrial automation showing up in HVAC. HVAC Controls, optimizing HVAC, boiler and pump control, heat pump and chiller optimization, environmental controls wireless control, computer control, and bulding automation. As energy costs continue to grow in relation to overall operating costs, the need for more refined HVAC control becomes more crucial. HVAC strategies such as optimizing start-up time and supply air temperature, and minimizing fan energy and reheating are not only possible, but are becoming necessary. This book examines the relationship between industrial automation techniques and evolving VHAC systems, and how emerging technologies can now be applied to HVAC systems.

Since the publication of the first edition in 1992, the HVAC industry has gone through enormous changes. As simple digital systems have given way to more complex systems, demand for information on how these systems operate, how they are best applied and how they communicate with other building control systems has grown rapidly. Direct Digital Control for Building Systems, Second Edition is thoroughly updated and expanded to include coverage of the architecture of modern digital control systems, distributed intelligence networked systems, communication protocols, the technologies and issues concerning interoperability, the latest application strategies, and defensive techniques for designing and specifying control systems. Numerous illustrations throughout help keep the subject highly accessible, and hardware, software, and systems applications are described in the most universal terms possible. This thoroughly revised second edition also contains a full section on BACnet® standard and Echelon's LonWorks® technology; their meaning, applications, and future implications. An up-to-date appendix is provided. Insights on emerging technologies in intelligent control systems and what the future holds for this dynamic field is covered throughout.

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.
