Thermal Performance Analysis of Instant Juice Chiller

Abstract

The presented paper projects on the design, manufacture, and thermal performance analysis of a refrigerated fluid dispensing apparatus. The device is manufactured to maintain the fluid at a low temperature by a suitable refrigeration system and to dispense the refrigerated fluid as on-demand. The Coefficient of Performance is drawn at various flow rates. The vapor compression system with modification in the evaporator is designed and manufactured. The results show that the Coefficient of Performance is maximum at 1.5 lit/min flow rate by considering water as a working fluid and 1.5 lit/min for Juice as a working fluid. The equipment gives the instant effect of cooling for both of the fluids like water and Juice. There is not much difference in the performance for both of the fluids as there is no considerable density difference. The Coefficient of Performance of the equipment tends to increase as the flow rate increases. The total energy consumption reduces as it takes very little energy as input. In existing models, there is no provision to change the flow rate of the juice whereas in instant chiller the flow of fluid can be changed as per the requirement. The instant chiller chills the juice instantly as and when required. There is no need to run the machine continuously.
