On the basis of calculation method for temperature distribution with no phase change

the condensing curves searched from professional physical property software or physical property data base were fitted to obtain the correlation equations of enthalpy-temperature and gas phase fraction-temperature.Then an improved calculation model for temperature distribution in condensers was proposed

which can obtain the temperature distribution through iterative calculation.Finally

this model was applied in temperature distribution calculation for shell side condensing and tube side condensing.Compared with the results calculated by the HTRI software under the same conditions

the results by this method has an error within 6%

which proves that this computation model is feasible and accurate.
