Issues regarding the refrigerant in cooling systems
Thread Content
In modern chemical production, cooling processes are employed, and the refrigerants used include brine as well as aqueous solutions of ethylene glycol. Which one provides a better cooling effect?
Saline solutions have a strong corrosive effect on metals, and therefore can corrode pipes and equipment； Its corrosivity is related to the purity of the salt and the oxygen content in the solution; it is recommended to minimize exposure of the solution to air by using a closed-loop system or by covering the salt water tank ； Ethylene glycol aqueous solutions pose no corrosive threat to equipment, but they have low volatility; it is recommended to use a closed-loop system ； It depends on the company’s requirements. Are there any other questions you’d like to ask me? I look forward to growing together. Thank you!
It depends on your company’s requirements. Cold brine is corrosive to pipes; moreover, their specific volumes should be roughly similar
As a supplementary point, cold saline solution absorbs moisture from the air; therefore, as it is used for an increasingly long period of time, the specific gravity of the saline decreases
It mainly depends on the cooling requirements of the substance you need; in fact, there isn’t much difference – it’s just a matter of which option is more cost-effective.
Cold saline is generally used; its advantages and disadvantages have been discussed in great detail, and moreover, its cost is relatively low.
