Introduction to the principle of the liquid nitrogen system
The LDH small liquid nitrogen machine is a plug-in liquid nitrogen solution. Using mixed working medium refrigeration MRJT process, based on the regenerative type multiple mixed working medium throttling refrigeration cycle, from the ambient temperature to the target refrigeration temperature, the preferred high and low boiling point pure mass group elements to form multiple mixed working medium, to achieve the relay matching of effective refrigeration temperature zone, is a kind of refrigerator can efficiently achieve-40~ -196℃ temperature zone.
Technical features of the LDH liquid nitrogen machine
The compressed air passes through the air compressor, enters the PSA nitrogen generator, and passes through the sterilizing filter to generate sterile nitrogen with dew point-60℃. Sterile nitrogen enters the refrigeration system and liquefaction into liquid nitrogen and is stored in the liquid nitrogen tank.
