Abstract— The aim of this paper is to address the energy demand and its maximum utilization of available energy in many industries. In this paper a simple Vapour compression Refrigeration System available in a dairy plant is taken as a system for analyzing its energy transactions. The ammonia which is used as a refrigerant typically reaches a temperature of around 120 °C. Further the dairy plant also requires hot water and steam for its working which is met by a separate wood fired boiler. The heat energy of ammonia is untapped until now. Based on the energy audit carried out now it is recommended to introduce a Double pipe heat exchanger in which the untapped heat energy of ammonia is transferred to water for producing steam and hot water for the internal need of dairy plant. This in turn cuts the usage of boiler and results indirectly in savings of fuel cost.
