Consider a water-to-water double-pipe heat exchanger whose flow arrangement is not known. The temperature measurements indicate that the cold water enters at 20°C and leaves at 50°C, while the hot water enters at 80°C and leaves at 45°C. Do you think this is a parallel-flow or counter-flow heat exchanger? Explain.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
Consider a water-to-water double-pipe heat exchanger
whose flow arrangement is not known. The temperature measurements
indicate that the cold water enters at 20°C and
leaves at 50°C, while the hot water enters at 80°C and leaves
at 45°C. Do you think this is a parallel-flow or counter-flow
heat exchanger? Explain.
