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.

Abstract: A portable housing holds a quantity of ice and water and the water is circulated through a heat exchanger. A blower circulates air from the room in which the housing is disposed 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 and the heat exchanger are 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.

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.

Abstract: Insulative roof apparatus includes flexible layers of different materials, including insulation and sealing materials, all of which are flexible, to withstand movement of the roof of mobile homes and similar buildings.

Abstract: Roof apparatus is disclosed for mobile homes and the like which includes several discrete layers of different types of materials, including insulation materials, bonding materials, and sealing materials, which together provide insulation from heat and cold from the mobile home structure and the structural strength requirements for minimizing damage to the mobile home by normal flexing of the mobile home, such as resulting from wind.
