| Abstract: | Analyzes heat transfer for the operation principle of hybrid condenser which is combined with steel coil and PVC package and comes up with using the logarithmic temperature difference between condensing temperature and air wet bulb temperature to calculate the heat rejection simply.In addition,shows an integrated heat transfer coefficient of this hybrid condenser correlated the heat transfer of coil together with package.And makes points of the influencing factors on heat transfer of coil.Simultaneously points out that the usage of steel coil or PVC package for heat transfer depending on air flow proportion. |
