First, project analysis
The micro-sized nitrogen liquefier uses a cryogenic mixed working medium throttling refrigerator as a cold source, and the structure is tight.
Together, it can supply liquid nitrogen continuously and conveniently, and can be used as a supply source for small amounts of liquid nitrogen in the region.
widely used in:
Food: quick-frozen, fresh-keeping, processing
Medical: cryotherapy, vaccine storage, beauty, etc.
Material: cryogenic treatment, cold assembly, processing, etc.
Research education: scientific experiments, demonstration experiments, etc.
Creature: Biological Tissue Storage
Fundamental
The nitrogen liquefier is a cryogenic mixed working section driven by a single compressor with pre-cooling.
The flow chiller achieves the need for nitrogen liquefaction (-180 ° C). Cryogenic mixed refrigerant throttling system
The cold machine is based on a regenerative multi-component mixed-solution throttling refrigeration cycle, from ambient temperature to
Standard refrigeration temperature, preferably high, medium and low boiling point pure component composed of multiple mixed working fluids
The relay matching of the effective cooling temperature zone of each boiling point component is an efficient implementation of -40~-
Refrigerator in the 196 °C temperature zone.
Technical advantages
The chiller adopts multi-environmental environmental protection refrigerant with independent intellectual property rights.
The cold box adopts the unique secondary foaming technology to achieve good insulation effect.
The refrigeration system uses conventional air-conditioning compressors, and other components are easily available.
Compared with traditional Sterling and GM machines, the chiller does not require regular maintenance and high reliability.
Long service life
The liquefier has a one-button power-on function, and automatically enters the liquefaction mode after a key is turned on.
formula
The machine has a simple process, normal production, high degree of automation, easy start-stop, less wearing parts, easy maintenance, low production costs.
