What is the consequence of blocked swirls in a vertical shell and tube condenser?

• A. Increased efficiency
• B. A need to lower water flow
• C. Decreased heat transfer capacity
• D. Improved refrigerant flow

Answer: (C)

When swirls in a vertical shell and tube condenser are blocked, the primary consequence is a decrease in heat transfer capacity. Swirls are created to promote turbulence in the fluid, which enhances the heat exchange process by increasing the contact between the refrigerant and the cooling water. When these swirls are blocked, the flow becomes more laminar, resulting in less mixing and therefore less effective heat transfer. This reduced efficiency can lead to higher operating temperatures and lower refrigerant performance, negatively impacting the overall functioning of the condenser system. In comparison to the other choices, increased efficiency is not a result of blocked swirls, as they contribute significantly to optimal heat transfer. Lowering water flow may be a response to issues but does not directly relate to the consequences of blocked swirls. Improved refrigerant flow would also not occur; rather, flow issues may arise from such blockages, leading to further complications. Hence, decreased heat transfer capacity is indeed the direct outcome of blocked swirls in the condenser.
