COOLING PROCESS AND APPARATUS

摘要

A method of cooling air and a cooling apparatus is disclosed wherein primary air is passed through at least one primary chamber to provide secondary air at an outlet of the primary chamber. Secondary air is passed in a counterflow direction through at least one secondary chamber which is in heat exchange relationship with the primary chamber. An evaporative fluid is applied to the secondary air and optionally to a downstream portion of the primary air in the primary chamber. This causes cooling of the downstream portion of the primary air and of the secondary air and of the evaporative fluid and simultaneously causes cooling of the primary air in the primary chamber by reason of the heat exchange relationship between the primary and secondary chambers. A turbulent boundary layer can be created in the secondary air by introducing a portion of the primary air directly into the secondary chamber from the primary chamber.
