Summary

THIS SERIES OF ARTICLES CONSTITUTES A STATE OF THE ART SURVEY OF ELECTRONIC CONTROLS APPLICABLE TO REFRIGERATION, AIR-CONDITIONING AND BUILDING MANAGEMENT SYSTEMS, TOGETHER WITH SOME DISCUSSIONS OF NON-ELECTRONIC CONTROLS AND THEIR RELEVANCE TODAY. THE AUTHORS CONCENTRATE ON TWO MAJOR FIELDS, OFFICE COMPLEX AIR-CONDITIONING, AND SUPERMARKET REFRIGERATION. ADVANTAGES OF COMPLETE, FULLY ELECTRONIC, BUILDING CONTROL SYSTEMS INCLUDE FACILITIES SUCH AS THE ABILITY TO CALL UP DATA FROM A DISTANCE, ENABLING A SERVICE ENGINEER TO ANALYSE RECORDED INFORMATION ON A MONITOR SYSTEM AND DETERMINE THE CAUSE OF A FAULT. MOST DUTIES CAN NOW BE ELECTRICAL/ELECTRONIC, AND SO INTEGRATED INTO A CENTRAL CONTROL SYSTEM. EVEN THE REFRIGERANT EXPANSION VALVE MAY BE CAPABLE OF OPTIMISING SUPERHEAT AND HENCE EVAPORATOR PERFORMANCE ON A CONTINUALLY CHANGING BASIS. PNEUMATIC AND COMBINATIONS OF PNEUMATIC WITH ELECTRONIC CONTROLS ARE ALSO DISCUSSED. D.W.H.
