Abstract
The main air stream (1) in a room is cooled by passing it along the dry duct (3) and simultaneously passing the auxiliary air stream (7) that has been taken from the atmosphere in a countercurrent flow along the moist duct (9), which is in heat-exchange interaction with the dry duct (3). To provide more intensified cooling the auxiliary stream (7) is precooled in another dry duct (8), which is in heat-exchange interaction with another moist duct (6), by passing a part (5) of the precooled air taken up from the main stream (1), while a part (4) of air is returned to the room. The auxiliary stream (7) is flowing with the aid of an air exhauster (10).
Claims1
A method for indirect-evaporative air cooling, consisting in that air is cooled by passing its main stream (1) along a dry duct (3) and simultaneously passing an auxiliary air stream (7) in a countercurrent flow along a moist duct (9), which is in heat-exchange interaction with said dry duct (3), characterized in that the auxiliary air stream (7) is precooled by being passed along another dry duct (8), which is in heat-exchange interaction with another moist duct (6) along which is passed countercurrently a part (5) of the precooled air taken up from the main stream (1), flowing of the auxiliary air stream (7) being effected by sucking it out of the moist duct (9).
