Heat Exchanger Effectiveness Calculator | Thermal Performance Tool

Heat exchanger effectiveness Tool Formula:

\[ \epsilon = \frac{Q_{actual}}{Q_{max}} \]

\[ \epsilon = \frac{T_{hot,in}-T_{hot,out}}{T_{hot,in}-T_{cold,in}} \]

(where Q_actual = actual heat transfer, Q_max = maximum heat transfer, T_hot = hot fluid temperature, T_cold = cold fluid temperature)

The Heat Exchanger Effectiveness Calculator allows the engineer, students, and HVAC or chemical process professional to calculate the thermal effectiveness of a heat exchanger and display the efficiency of heat transfer through the hot fluid into the cold fluid. The ratio of the actual heat transfer to the maximum possible heat transfer is referred to as heat exchanger effectiveness (ε).

The users may enter the hot and cold fluid inlet/outlet temperatures, heat capacity rates (Cmin, Cmax), and NTU (Number of Transfer Units). The calculator calculates the effectiveness ( ε ), heat transfer rate (Q), outlet temperatures, and temperature differences by type of heat exchanger, including counterflow, parallel flow, or crossflow.

The performance of shell-and-tube, plate, and air-cooled heat exchangers is easily analyzed using step-by-step solutions to show the flow of energy and temperature in each configuration. The units which are supported include: kPa, o C, K, kW. It is the best tool that would be used by mechanical engineers, chemical engineers, HVAC engineers, and students to guarantee the correct assessment of heat exchanger efficiency and performance.
