Abstract:
A cooling system utilizing a carbon dioxide refrigerant comprising:a liquid carbon dioxide reservoir, the liquid carbon dioxide reservoir containing a quantity of carbon dioxide in a liquified state; a regulator connected to the liquid carbon dioxide reservoir, the carbon dioxide flowable through the regulator, the regulator for reducing the pressure of the liquid carbon dioxide flowing through the regulator; a cooling coil, the cooling coil for connecting the regulator to an atmosphere; a flow of carbon dioxide established by a movement of the carbon dioxide from the liquid carbon dioxide reservoir, through the regulator, into the cooling coil, and to the atmosphere; and a plurality of solid carbon dioxide particles formed by a freezing of the carbon dioxide within the cooling coil, and the flow of the carbon dioxide into the cooling coil substantially blocked by the plurality of solid carbon dioxide particles within the cooling coil, the plurality of solid carbon dioxide particles sublimate-able to allow a re-establishment of the flow of carbon dioxide.
