| abstract |
Stand-alone and self-accepting cooling systems are disclosed, consisting of specially designed units using compressed liquid and / or gaseous CO 2 containers located in insulated and non-insulated containers, the containers being positioned vertically in an upright or inverted position. Liquid and / or gaseous CO 2 coolant is released into the capillary tube (s) embedded in the heat transfer plate or heat exchanger, and thus utilizes the CO 2 coolant properties. The temperature can be operated remotely and / or via a touch screen and controlled by a metered CO 2 emission system that includes an electronic control device that alerts when a predefined threshold is exceeded. The metered CO 2 emission system of the present invention can be started by an electronic or thermostatic valve or can be started manually or by an electronic solenoid. The cooling system of the present invention also includes a check valve that prevents liquid and / or gaseous CO 2 from leaking when the CO 2 containers are individually removed or replaced. |
