The study on heat and mass transfer of the fin-and-tube condenser with spray evaporating

The usage of the evaporative condenser can bring about the reduction of the irreversible loss from the heat transferring in the refrigerating device,and increase the efficiency of the mechanism.This article advances the application of the fin-and-tube condenser with spray evaporating to the refrigerating device,analyzes the heat transfer process of the fin-and-tube condenser under the sprinkling operational conditions,establishes the heat and mass transfer numerical model and the method for designing and calculating.The influence to the heat and mass transfer function by some main factors is also analyzed concisely,such as the temperature and the humidity of the environment,the construction of the finned tube,the air velocity,the quantity of spraying water and so on.All of that will provide the theoretical reference for the design and application of this kind of condenser.
