Concept explainers

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.

Q1) A heat exchanger is to be designed to heat 32/68 mixture of ethylene glycol and water from 24 ᵒC to 55 ᵒC by a hot water stream from 79 ᵒC to 42 ᵒC. Flow rate of cold stream is 20 kg/s. Inlet pressure for both stream is 50 psi and the maximum pressure drop of 10 psi for cold stream and 8 psi for hot water are permissible. Report valid assumptions made for the design and give required justification.

In the evaporator of an air conditioning system, air flows over finned tubes through with the refrigerant R134a flows. air out refrigerant in refrigerant out air in The mass flow rate of the air is 0.75 kg/s and the air enters at 40°C and pressure 1.04 bar. The air leaves the evaporator at 25°C and 1.01 bar. The refrigerant enters the evaporator with a quality of 0.2 and a temperature of 12°C. The refrigerant exits as saturated vapor. Obtain the properties of air and R134a using the fluids "Air" and "R134a" in EES. What is the volumetric flow rate of the air entering the heat exchanger (m^3/s)? Determine the rate of heat transfer from the air to the refrigerant (W). Determine the mass flow rate of the refrigerant (kg/s).
