Abstract
A method and apparatus provides conditioning of an air stream by cooling in a regenerative heat exchanger having two groups of channels separated from one another by walls through which heat exchange occurs. The air stream to be conditioned flows through one group of channels while an auxiliary air stream flows through a second group of channels the walls of which comprise wettable material maintained wet by means of water which is caused to evaporate by the auxiliary air stream to result in cooling. The wettable material provides a substantially stationary liquid layer maintained in the channels of auxiliary air flow so that evaporation takes place directly from the walls separating the two groups of channels to obtain high heat exchange efficiency. The wettable material may be wick-like absorbing material layers which eliminate the requirement of continuously flowing large quantities of water so that the evaporative surfaces may be rewetted intermittently and kept wet over a period of time prior to subsequent rewetting. This is accomplished by providing an excess amount of water. In addition, intensive rinsing of the evaporative surfaces may take place to remove dust particles and mineral deposits occurring in the water. The auxiliary air stream may be split off from the stream of air to be conditioned before and/or after the air stream has been conditioned by cooling to provide greater efficiency.
