Abstract: An evaporative cooling membrane device is disclosed having a flat or pleated plate housing with an enclosed bottom and an exposed top that is covered with at least one sheet of hydrophobic porous material having a thin thickness so as to serve as a membrane. The hydrophobic porous material has pores with predetermined dimensions so as to resist any fluid in its liquid state from passing therethrough but to allow passage of the fluid in its vapor state, thereby, causing the evaporation of the fluid and the cooling of the remaining fluid. The fluid has a predetermined flow rate. The evaporative cooling membrane device has a channel which is sized in cooperation with the predetermined flow rate of the fluid so as to produce laminar flow therein. The evaporative cooling membrane device provides for the convenient control of the evaporation rates of the circulating fluid by adjusting the flow rates of the laminar flowing fluid.

Abstract: 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.

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.

Abstract: Apparatus for periodically draining, flushing and replacing the water supply in an evaporative cooler during operation thereof and for completely draining the cooler when its operation is terminated. The apparatus includes a siphon drain valve mounted in the sump of the cooler and configured for movement between siphoning and non-siphoning positions with the movement being controlled by a solenoid. When the cooler is in normal operation, the solenoid is deenergized which places the siphon drain valve in the non-siphoning position and when in such normal operation, the water supply will increase in mineral salt concentration and other cooler damaging contaminants. At periodic intervals, such as under control of a time clock, the apparatus is switched to its draining, flushing and water replacing operation mode. This is accomplished by energizing the solenoid to initiate the siphoning action of the siphon drain valve to drain the water from the cooler.
