Résumé

A fluidised bed heat exchanger was tested as an ice slurry production method in order to determine a possible working range. Heat transfer rates during ice slurry production were measured and evaluated. The heat transfer rates measured were high when compared with other ice slurry production methods. Experiments have shown that the temperature difference between the primary refrigerant side and the ice slurry side is a critical parameter to make ice slurry production in the fluidized bed heat exchanger possible over longer periods. At too high temperature differences a permanent ice layer is formed on the heat exchanging walls, at too low temperature differences the heat flux is not high enough to overcome pumping power input and other heat losses. Other parameters important for the ice slurry production are the superficial velocity of the ice slurry flowing through the fluidized bed and the ice concentration already present entering the fluidised bed. The degree of supercooling at the start of ice formation was also investigated, because this supercooling effect probably contributes to instability of the ice slurry production.
