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.

Question

23–78C Consider a shell-and-tube water-to-water heat ex-
changer with identical mass flow rates for both the hot- and
cold-water streams. Now the mass flow rate of the cold water
is reduced by half. Will the effectiveness of this heat exchanger
increase, decrease, or remain the same as a result of this modi-
fication? Explain. Assume the overall heat transfer coefficient
and the inlet temperatures remain the same.

A heat exchanger is being investigated as a waste heat recovery device. A heat exchanger is common device for using a hot fluid to heat a cold fluid without the fluids mixing. The following information is known. The cold fluid stream of liquid A enters at 294.2 K and leaves the device at a temperature of 320.91 K. Liquid A flows at a rate of 0.006 Kg/s and has a specific heat of 4180 J/(Kg K). Liquid B enters the device at a temperature of 350.2 K. Liquid B flows at a rate of 0.005 Kg/s and has a specific heat of 3900 J/(Kg K The dead state is at 293.2 K and 1 bar. The device is adiabatic and the pressure losses are neglected in this problem. Both liquids are incompressible materials. Tout=316.154K Answer the following: If the exiting liquid B is not used for any useful purpose, calculate the exergy destroyed associated with it.
It is desired to heat 230 kg / h of water from 36 to 94 ºC with oil (Cp = 2.1 kJ / kg ºC) that has an initial temperature of 175 ºC. The oil mass flow is also 230 kg / h. It has a double tube exchanger in parallel, with a total heat transfer coefficient of 570 W / m2 ºC. Calculate the total surface area of the heat exchanger.

This is done in an oil-water het exchanger that receives 2 948 kg/h of water at 15.6 Celsius. For the exchanger, U = 295 W/m2-K.

A long, thin-walled double-pipe heat exchanger with tube and shell diameters of 0.01 m and 0.025 m, respectively, is used to condense refrigerant-134a with water at 20°C. The refrigerant flows through the tube, with a convection heat transfer coefficient of hi= 4100 W/m² °C. Water flows through the shell at a rate of 0.3 kg/s. The thermal resistance of the inner tube is negligible since the tube material is highly conductive and its thickness is negligible. Both the water and refrigerant-134a flows are fully developed.
