Author(s) : HE W., RUNQING Z.

Summary

The gravity feeding refrigeration system uses the principle of Thermosyphon to supply the refrigerant with large amount of liquid as the way of liquid refrigerant supply.The refrigerant supply in the evaporator is greater than the refrigerant evaporation, which ensures that the evaporation tube always keeps sufficient wetted,the flow velocity of refrigerant in the evaporating tube is improved, so that the convection heat transfer of the refrigerant side is strengthened, and the heat exchange efficiency of the evaporator is improved.The mathematical model of evaporator in gravity feeding refrigeration system is established.The new evaporators with an area of 90%, 85%, 80%, 75% and 70% of the original evaporator area is simulated in the simulation, and the most suitable evaporator used in the experimental cold storage is selected.The evaporator is processed and applied to the experiment, and the performance of the evaporator is compared with that of the original evaporator.It is concluded that the evaporator area is 75% of the original evaporator
area, which is the best match with the experimental cold storage.
