ABSTRACT:
A temperature regulation apparatus includes a dry ice module that encloses dry ice so that the module's outside surface is not hazardous to touch. Insulation, breathable material, or a combination of insulating and breathable materials, allows dry ice sublimation at a sufficiently slow rate within the attached dry ice module to control the ambient temperature in the area to be cooled. The dry ice module can be attached in a location that maximizes the dry ice cooling properties, typically at or near the top of the area to be cooled. Since sublimated carbon dioxide is heavier than normal air, it falls to the bottom of the area to be cooled and builds up. The venting placement in the dry ice module is based upon the make up of the dry ice module and the breathable materials inside of it.
