In the age of globalisation energy saving has become significant. It has led to the increased energy and cost concern which encouraged an investigation of waste heat recovery from bulk milk chillers as a conservation alternative for reducing heat cost in diary industry. Milk chilling equipment used depends on the quantity of milk required to be handled. In coolers (BMC) ie. milk production practices the harvested milk is chilled from its initial temperature of 35 °C to 4 °C to arrest the bacterial growth and maintain the quality of milk. Milk chilling process by using BMC is energy intensive process. Hot water is used in dairy industry to clean all dairy processing equipment which is heated separately by using oil and gas as a fuel or electrical energy. This amount of energy required for water heating is saved by recovering and utilizing heat dissipated to atmosphere through condenser is recovered using a heat pump which saves the strain on the electric energy used to heat the water separately and eventually helped lessening the expenditure. An attempt has been made to design a tube in tube type heat exchanger capable to recover heat during the condensation process. Experimental investigations are done for water instead of milk which has nearly similar properties. In this paper energy saving potential in 150 litre capacity bulk milk cooler through heat recovery tube in tube type heat exchanger. It is revealed that there is considerable energy saving potential in bulk milk cooling systems. Significant improvements have been achieved and coefficient of performance (COP) of the system is about 2.73
