SCADA System for HVAC

Over the recent years, Process control systems have found application in many new areas. Integration of knowledge from Computational Intelligence, Telecommunication and Microarchitectures, has led to evolution of many different flavors of process control like Distributed Control System (DCS), Supervisory Control and Data Acquisition System (SCADA) etc. This book describes development of SCADA system for Heating Ventilation and Air Conditioning System. Introduction of Process control logic in a HVAC system helps to optimize its power consumption. SCADA system described in this book is based on an actual project undertaken in 2009 at GIK Institute, Pakistan. HVAC system discussed comprises of 100HP Electrical load and 250 tons of air conditioning load. Effectiveness of introduced SCADA system can be judged by the saving rate of 96% at a negligible operational cost of 3%. Discussed SCADA system is based on innovative use of readily available components for inexpensive development. This text should be particularly helpful for those who are considering customized development of a process control system.
