Abstract
The invention introduces a cellular air bag insulator and its uses in insulating a house window, a house door, a house wall and process equipment, such as an evaporator, a refrigerator and a distillation column. A cellular air bag insulator is a light weight insulator and comprises an outer enclosed bag and an expansible and collapsible multicompartment core such as a honeycomb structure joined to the outer bag. It can easily be inflated and deflated. When it is inflated, multitude of horizontal air compartments in multilayers are formed in the bag to provide a high resistance to heat transfer through the bag by reducing convective flow of air within the bag and by requiring the heat to pass through the multilayers of air compartments. When it is deflated, it occupies a rather small volume and can be rolled up or folded into a compact form that is convenient to handle and store. When a cellular air bag insulator is inflated, its edges press against the walls of a confining frame and/or its front surface press against the surface to be insulated to prevent air flow around the insulator. There is no need for an elaborate mounting frame or special brackets.
