Industrial Refrigeration Handbook Stoecker By Wilbert F. Stoecker

Nevertheless, industrial refrigeration is a lively business of significant size, provides many technical challenges to its practitioners, and serves a crucial role in industry and society. While there is always a danger in isolating one’s area of technical activity and thus losing the input from related fields, industrial refrigeration should not be considered a branch of comfort air conditioning. Industrial refrigeration is characterized by special rather than standard jobs, and the fraction of total cost devoted to engineering and design usually is higher than with air conditioning. Many problems can occur in the lower temperatures typical of industrial refrigeration plants that do not occur in the usual comfort air conditioning temperatures. The refrigeration plant for an air conditioning system is usually a factory-assembled package ready for connection to electrical, water, and air services. In industrial refrigeration, built-up systems are more common than complete packages because of the great variety of installations. Another distinguishing feature is that industrial refrigeration systems usually consist of parallel compressors, condensers, and evaporators in contrast to packages with one of each of these components serving a comfort air conditioning assignment. When an industrial refrigeration plant is expanded, it is usually done by installing an additional compressor, condenser, and/or evaporator.
