Difference between throttle valve refrigeration and expansion mechanism refrigeration
Thread Content
What is the difference between throttling valve refrigeration and expansion mechanism refrigeration? It seems that throttling valve cooling is simpler and requires less investment, but why is expansion mechanism cooling also widely used? I would like to ask about the advantages and disadvantages of each method, and how to make a choice Thank you!
It seems that the capacity for throttling-based refrigeration should be lower than that of expansion-based refrigeration.
It mainly depends on the amount of cooling required and the operating pressure level.
Could you be more detailed? 》Thank you!
1. Throttling expansion is applicable to gases and liquids, while expanders are used for gases； 2. Expanders are used more at low pressure; for medium pressure and low temperature, both throttling expansion and expanders can be employed ； 3. Use an expander under high temperature and pressure.
