For lithium bromide units, what should be done when the user load decreases?
Thread Content
Hi, may I ask? When the user load decreases, it means that the heat exchange equipment needs to be shut down, as there is no longer a need for heat exchange. At this point, the cooling capacity of the unit is sufficient; the return water temperature is 7.4 degrees, while the supply water temperature is 7.1 degrees. Is it correct to adjust the cold water supply volume at the moment? As of now, I know that controlling the cooling capacity involves reducing the flow of steam and circulating water. But it seems necessary to reduce the cold water flow as well; however, I haven’t tried it yet. When the temperature of the circulating water is high, it is necessary to turn on the fan; however, once the temperature drops, the temperature of the water also falls by 7 degrees.
If the amount of chilled water decreases while the amount of circulating water and steam remains unchanged, the cold energy generated inside the unit cannot be removed, which can easily lead to damage to the heat exchange tubes.
I didn’t expect this; thank you so much
