Abstract

A portable housing holds a quantity of ice and the melt water from the ice or cooled water or cooled liquid is circulated through a heat exchanger. A blower circulates air from the room through the heat exchanger and back into the room for cooling the room. The housing includes a relatively large chamber for holding the ice and a relatively smaller chamber in which the blower is disposed. Melt water from the ice, or cooled water or cooled liquid, is pumped through the heat exchanger and from the heat exchanger the liquid flows by gravity back to the ice and water chamber. An alternate embodiment is disclosed in which there is a closed loop liquid heat exchange system by which a coil is disposed beneath the ice and is cooled. A pump continuously circulates the liquid in the closed loop, with the heat exchanger through which air is blown is part of the closed loop system. The apparatus may also be used as a portable heater by using hot water instead of cold water in the heat exchanger.

Dependent claims

Apparatus for cooling a room comprising in combination:

a housing, including
a bottom,
a pair of side walls secured to and extending upwardly from the bottom,
a rear wall secured to the bottom and to the side walls,
a front wall secured to the bottom and to the side walls remote from the rear wall,
an opening in the front wall,
a top secured to the side walls, the rear wall and the front wall,
a first opening in the top adjacent to the front wall,
a second opening in the top adjacent to the rear wall, and a lid closing the second opening in the top;
a vertical wall extending downwardly between the sides from the top between the first and second openings in the top and terminating above the bottom;
a horizontal wall extending between the vertical wall and the front wall below the opening in the front wall;
heat exchanger means for receiving a cooling medium;
a cooling medium in the heat exchanger;
means for cooling the cooling medium in the heat exchanger;
means for pulling air through the opening in the front wall and past the heat exchanger to cool the air and for blowing the cooled air out through the first opening in the top;
and
means for circulating the cooling medium in the heat exchanger means.
