Question

Quizplus · Accepted Answer

When the condenser tubes are dirty, heat transfer between the refrigerant and the water is hindered, resulting in a smaller temperature difference compared to when the tubes are clean. As a result, the temperature difference between the refrigerant and the leaving water will be greater when the tubes are clean, as the heat transfer will be more efficient.
