Condensate retention on hydrophilic heat exchangers: retention data and modelling.

Author(s) : LIU L., JACOBI A. M.

Summary

A study of condensate retention is presented for fin-and-tube heat exchangers typical to those used in air-conditioning applications. An experiment in which the retained mass of air-side condensate was measured under dynamic conditions is described, and the amount of retention was found to depend on the air-side Reynolds number and latent heat transfer. Based on filmwise condensation assumptions, a new model for predicting the mass of retained condensate on hydrophilic heat exchangers is described and compared to the steady-sate retention data. The model is successful in predicting retained condensate over a wide range of test conditions.
