Waste Heat Recovery from the Vapour Compression Refrigeration System & Its Utilization in Processes

To conserve energy, necessary steps are taken all over the world which results higher savings, improved environmental quality. Heat is low grade energy. Though it is low grade energy, but its recovery can give low fuel consumption in any typical application. So many work is being done to recover the waste heat in Refrigeration Systems. An attempt has been done to explore the waste heat recovery from the refrigerant ammonia gas between the Single stage reciprocating compressor and condenser of Vapour Compression Refrigeration system used in the beverages bottling plant. This low grade waste heat recovery improves the performance of the Refrigeration system and the recovered heat is utilised for heating of the Carbonated PET bottles and Cleaning in Place (CIP). The recovered low grade heat reduces the condenser load hence improved performance of the refrigeration system.
