Coolant selection issue! ! !
Thread Content
In the past, when working in state-owned enterprises, aqueous solutions of sodium chloride and calcium chloride were commonly used as refrigerants. Later, in a joint venture, ethylene glycol was used; now, the current company chooses methanol. It seems dangerous, as inorganic salts are highly corrosive. Ethylene glycol is expensive, while methanol is cheap, does not corrode equipment, and can be reused as a production waste fluid. Let’s discuss what would be the best option! ! !
At the same time, factors such as the unit cost of cooling capacity, risk level, operational stability, and corrosivity need to be taken into comprehensive consideration.
