VACUUM INSULATED SORBENT-DRIVEN REFRIGERATION DEVICE

摘要

VACUUM INSULATED SORBENT-DRIVEN REFRIGERATION DEVICE 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. ¢JRR-2086! JRN-6347:/pd 010290 LIQUI.02A
