Abstract:
Methods of making vacuum insulation products are provided. One method includes providing an insulative mixture comprising an insulative material, such as silica, with a radiation absorbent material, such as carbon black, and applying electromagnetic radiation such as microwave radiation to the insulative mixture to dry the insulative mixture. The insulative mixture can then be placed into an enclosure and sealed within the enclosure. The enclosure can be evacuated before sealing to reduce the pressure within the enclosure to below atmospheric pressure. The use of radiation such as microwave radiation to dry the insulative mixture advantageously reduces the time required to fabricate the vacuum insulation product and can reduce the pressure that is obtained in the vacuum insulation product, thereby increasing thermal performance of the product.

An evacuated sorbent driven cooling device which may be added to a beverage or food container and which may also be affixed to, or integrated within, a panel of a beverage container.
Abstract:
The present invention provides an insulation panel comprising an air-impermeable container and disposed therein a gas and an adsorbent material that has a surface area of at least about 200 m.sup.2 /g and that adsorbs more of the gas at a temperature below about 0.degree. C. than at 22.degree. C., wherein the pressure in the container at -34.degree. C. is not more than about 80% of the pressure in the container at 22.degree. C. The present invention also provides a method of insulating a surface from environmental thermal effects comprising placing the insulation panel of the present invention over the surface to be insulated.
Abstract:
A method of preparing a vacuum insulation panel is disclosed. In the method of the present invention, a plurality of metal oxide-containing compacts, each of which contains less water than the amount of water contained therein at atmospheric equilibrium, are enclosed in a film that retards the passage of moisture therethrough. The film is breached and the metal oxide-containing compacts are positioned in an air-impermeable container at atmospheric pressure. The pressure is reduced in the air-impermeable container, and the air-impermeable container is sealed to form the vacuum insulation panel. Also disclosed is a vacuum insulation panel comprising a plurality of metal oxide-containing compacts disposed in an air-impermeable container, wherein the metal oxide-containing compacts contain less water than the amount of water contained therein at atmospheric equilibrium.
Abstract:
A method of compacting a fumed metal oxide-containing composition is disclosed. In the method of the present invention, the fumed metal oxide-containing composition is treated with vapor comprising water such that the vapor is adsorbed into the fumed metal oxide so as to produce a vapor-treated fumed metal oxide-containing composition. Pressure is applied to the vapor-treated fumed metal oxide-containing composition to reduce the volume of the metal oxide-containing composition so as to produce a compacted metal oxide-containing composition, which is characterized by a volume springback that is less than the volume springback of the same compacted metal oxide-containing composition prepared in the absence of said vapor treatment.
Abstract:
A sorption cooling system for providing cooled air to the cabin of a vehicle. The sorption cooling system includes an evaporator, a condenser adapted to fluidly communication with the evaporator, and a plurality of adsorbent beds adapted for fluid communication with the condenser and the evaporator. Each adsorbent bed includes a fluid impermeable casing, desiccant sheets having apertures therethrough, a refrigerant flow path for flowing a refrigerant proximal to a first side of the desiccant sheets, and a coolant flow path for flowing a coolant fluid proximal to a second side of the desiccant sheets. The apertures are a portion of one of the refrigerant and coolant flow paths.
