A condenser is to be fabricated from the heat exchanger tubing described in Problem 3.1 for a compressor that flows 950 lb/h of R-134a refriger- ant. Find the total required heat transfer rate, the heat required to desuperheat the gas, and the required length of tubing if the overall U-factor is 500 Btu/h⋅ft2⋅°F, the temperature leaving the com- pressor is 200°F, and the pressure is 185 psig. The condenser exit is saturated liquid at 185 psig and the water temperatures entering and leaving the condenser are 70°F and 80°F, respectively.

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.
