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.
