Closed-loop circulation of frozen saline
Thread Content
What are the advantages and disadvantages of closed-cycle and open-cycle frozen saline circulation? Can an open system be directly converted into a closed one? I welcome advice from all experts! On the 23rd day of the 12th lunar month, happy Lesser New Year to everyone! !
A sealed system is less prone to contamination and suffers less loss; an open system cannot be directly converted into a sealed one, and an expansion tank must be installed in a sealed system.
There is no such thing as a closed cycle; all equipment that uses chilled brine is inherently sealed. The chilled brine flows from the tank through a pump to the refrigeration unit and then back to the tank, thus forming a cycle. All discharge outlets are located on the tank, so there is no issue of contamination or lack thereof.
What was said on the 3rd floor is correct; the original poster’s wording is problematic. What exactly are the closed-cycle and open-cycle frozen brine systems referred to by the poster?
Actually, this question is quite interesting. No one discusses the issue of closed-loop circulation for circulating cooling water. However, the refrigeration system is worth exploring, mainly due to energy-saving considerations. However, designing a closed system is relatively complex, especially regarding the balance of resistance losses in various channels. Those who are interested can explore further. Including system process settings.
