Abstract: Disclosed is a self-contained, rapid cooling device that retains heat produced from the cooling process and can be stored for indefinite periods without losing its cooling potential. A liquid in a first chamber undergoes a change of phase into vapor which cools the first chamber. A second chamber forms a vacuum insulation about a third chamber which contains a sorbent. The sorbent in the third chamber is in fluid communication with the vapor and removes the vapor from the first chamber. The device is self-contained because a material in contact with the sorbent removes the heat from the sorbent to prevent the reduction in the cooling effect produced by the first chamber. In addition, a vacuum insulation about the third chamber keeps the heated sorbent from diminishing that cooling effect.

Abstract: Disclosed is a multi-staged desiccant refrigeration device which employs an evaporator combined with a multi-staged vapor desiccant/heat sink module which absorbs water vapor from the evaporator. A plurality of stage vapor desiccant/heat desiccant modules are incorporated in the device, the automatic staged opening and closing of the modules allowing for a continuous and more efficient refrigeration process.

Abstract: Disclosed is a self-contained, rapid cooling device that can be stored for indefinite periods without losing its cooling potential. A liquid in a first chamber undergoes a change of phase into vapor which cools the first chamber. A sorbent in a second chamber is in fluid communication with the vapor and removes the vapor from the first chamber. A heat sink material thermally coupled to the sorbent collects and irreversibly captures heat transferred from the vapor to the sorbent.
