What is a potential consequence of starting an absorption unit with too cold of cooling water?

Starting an absorption unit with too cold of cooling water can lead to crystallization, which is the formation of solid crystals from a solution. In absorption systems, the cooling water is crucial for maintaining the right temperatures and pressures inside the unit. If the cooling water is too cold when the unit is first started, it can cause the refrigerant or absorbent to become super-cooled, resulting in the precipitation of soluble components or the formation of solid crystals. This crystalline formation can clog the system, disrupt the flow, and potentially damage components, leading to operational issues.

In contrast, operational failure could result from various factors not solely linked to the temperature of the cooling water, while water blockage might occur due to other reasons. Increased efficiency is typically associated with optimal cooling conditions rather than extreme cold, illustrating how maintaining the correct temperature range is vital for proper functionality in absorption units.
