Method for refrigerating liquid carbon dioxide used for cooling and cleaning processes, involves increasing/decreasing power of cooling device based on temperature and pressure of liquid carbon dioxide inside storage vessel
Method for refrigerating liquid carbon dioxide used for cooling and cleaning processes, involves increasing/decreasing power of cooling device based on temperature and pressure of liquid carbon dioxide inside storage vessel
The method involves positioning a sensor (4) on the upstream of a storage vessel (3), so as to measure the temperature and pressure of liquid carbon dioxide (2) inside the storage vessel. The power of cooling device (1) positioned above the sensor, is increased or decreased based on the measured values of temperature and pressure of liquid carbon dioxide inside the storage vessel. An independent claim is included for device for refrigerating liquid carbon dioxide.
