Portable liquid cooling and heating apparatus
First Claim
1. Apparatus for cooling a room comprising in combination:
- a housing, includinga 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.

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.

13. Portable cooling and heating apparatus comprising in combination:
-
a housing having a bottom, a front end wall, a rear end wall, a pair of side walls, and a top wall; a first compartment in the housing; a first opening in the housing through which air flows into the first compartment; a second opening in the housing through which air flows out of the first compartment; a heat exchanger in the first compartment through which air flows; means for providing the flow of air into the first compartment, through the heat exchanger, and out of the first compartment; a second compartment in the housing for holding selectively a quantity of heating or cooling medium; a heat exchange medium flowing in the heat exchanger and responsive to the heating or cooling medium to heat or cool the air flowing through the heat exchanger;
the housing further includes a sump disposed beneath the first compartment, and the heat exchanger includes a drain for draining the heat exchanger in the sump, and the sump communicates with the second compartment; andbaffle means in the second compartment for providing a relatively long path for the heat exchange medium from the sump to the second compartment. - View Dependent Claims (14, 15)
