PORTABLE REFRIGERATING MACHINE AND COOLER BOX OR COOLER BAG USING REFRIGERATING MACHINE

摘要

PURPOSE: To provide a small and portable refrigerating machine which uses a liquefied gas giving no adverse influence to an environment or the like upon its emission to atmosphere, obtains a cooling effect by using the heat of vaporization of the liquefied gas, and can directly emit then the vaporized liquefied gas to the atmosphere. ;CONSTITUTION: When a liquefied gas bomb 1 is set and the amount of discharge of liquefied gas is set by a pressure reducing valve 3, the liquefied gas is supplied to a cooling tube 5 through a capillary tube from the liquefied gas bomb 1. The heat of vaporization of the liquefied gas in the cooling tube 5 causes a cooler box to be cooled in a vaporizing part. The vaporized gas is emitted to atmosphere through a liquid reservoir 6 connected to the cooling tube 5.;COPYRIGHT: (C)1996,JPO
