PORTABLE SELF-CONTAINED COOLER/FREEZER APPARATUS FOR USE ON COMMON CARRIER TYPE UNREFRIGERATED TRUCK LINES AND THE LIKE

摘要

a transportable container for the transport of refrigerated goods in freezing temperatures (below zero) or cooling (for example, 42u00b0f) includes a container (12) with a structural outer shell insulation (14, 15, 16, 17) with a door to access (21).the upper part (26) of the container (12) has a perforated screen (25), a pair of cutting cylinders (27, 28) spaced each other and containing a refrigerant liquid product, e.g. co2, are prepared on the screen (25). an led (32) for gas or liquid enters the cylinder (27, 28) and communicates with a valve opening and closing.an led (32) for feeding cooling liquid extract, free gas and the pressure in the cylinder (27, 28), in order to increase the co2 to a boil. when the co2 reaches its boiling point, the cylinder (27, 28), a fixing plate, and the cooling is very cold temperatures to cool the area where the load is placed.the gas is discharged through ducts in the copper cooling plate so as to generate a convection.
