Waste Heat Recovery from Refrigeration

Shortages of fossil fuels and subsequent increasing prices and curtailments of these fuels have combined to accelerate the development of alternate energy sources. Waste heat recovery is one time-proven method of replacing fuel resources. Waste heat recovery from refrigeration machines is a concept which has great potential for implementation in many businesses. If a parallel requirement for refrigeration and hot water exists, the installation of a system to provide hot water as a by-product of the refrigeration cycle becomes economically justifiable. This paper treats the history of the refrigeration machine, and the modern developments which have made available the system concept of waste heat recovery from refrigeration. A typical application is analyzed from an engineering and economic viewpoint, salient points of both considerations being clearly quantified
