ABSTRACT:
A portable evaporative cooling unit (10) is disclosed. A housing (12) has a front opening (46) and a rear opening (20). Air-permeable water absorption media (22) are disposed across the rear opening (20) of the housing (12). An electric motor driven fan (42) having fan blades (44) is disposed in the front opening (46) of the housing (12) for drawing air through the water absorption media (22). A supply conduit (94) connects a water pump (52) to an elongated horizontal spray bar (64) disposed above the water absorption media (22). The spray bar (64) extends substantially the width of the water absorption media (22) and has a plurality of spaced holes (72) in its upper surface for distributing water. A foam sleeve (68) is disposed around the entire length of the spray bar (64). The foam sleeve (68) absorbs water expelled from the plurality of holes (72) and distributes the water onto the water absorption media (22). A water tank (50) in the bottom of the housing (12) contains a submersible, self-priming pump (52). A water inlet (36) is connectable to an external water source for supplying makeup water to the water tank (50). A float valve (96) maintains a predetermined level of water in the tank (50) as water is consumed during the operation of the unit (10). The housing is mounted on a frame (14) and casters (16) are attached to the bottom of the frame (14) for providing portability to the unit (10).
