Résumé

Prediction of heat transfer in the evaporator of a refrigeration unit should be as accurate as possible for the successful operation of the whole appliance. The predictive methods used at present are empirical or semi-empirical, particularly for the heat transfer conditions relevant in practice, because theoretically consistent calculation of the heat transfer coefficient in nucleate boiling is not yet possible. One of these which are included in the VDI Heat Atlas and has been updated recently, is presented in the first main part below and is compared with experimental data for 55 fluids. In the second, eight more prediction methods from the literature are tested using the same experimental database, and the deviations between measurement and calculation are discussed in detail together with the different results calculated with the various methods.
