Software For Design Of Heat Exchanger
- SSP is our unique software developed for advanced heat exchange calculations. And is based on our extensive knowledge of heat exchanger technology.
- JavaScript is required for this form. PHE Works is a full featured tool for the thermal design and rating of plate heat exchangers used in single phase heat transfer applications.
Equations and Parameters
In this article, we will provide a brief overview of the different Unilab software, starting from the single heat exchanger to complete units. For the design and calculation of fin packed and smooth tube coils heat exchangers, also considering mixtures outside of the tubes, UNILAB COILS is the ideal program.
The heat exchanger design equation, Q = U A ΔTlm, can be used to determine the required heat transfer area, A, for a heat exchanger. The heat transfer area can be calculated after values have been determined or estimated for the required heat transfer rate, Q; the overall heat transfer coefficient, U, and the log mean temperature difference for the heat exchanger, ΔTlm, based on the values of several input parameters. Excel spreadsheet templates for calculating the heat transfer area needed for a heat exchanger are presented and discussed in the next section.
For more details about preliminary heat exchanger design, the parameters involved, and example heat exchanger calculations, see the articles: 'Preliminary Heat Exchanger Design Example' and 'Fundamentals of Heat Exchanger Theory and Design.'
Excel Template – Page 1: Calculation of Heat Transfer Area
The Excel spreadsheet template shown at the left will calculate the heat transfer area required for a heat exchanger after values for several parameters have been input. The parameters that need input values are the mass flow rate, specific heat, inlet temperature and outlet temperature of one of the fluids; the heat capacity, inlet temperature and outlet temperature of the second fluid; and an estimated value for the overall heat transfer coefficient. After values are entered for those parameters the Excel formulas in the spreadsheet will calculate the heat transfer rate, the log mean temperature difference, the required heat transfer area, and the needed mass flow rate for the second fluid.
Column C has cells for entry of several parameter values. Column I contains the Excel formulas to calculate the parameters noted above. This example spreadsheet shows calculations in U.S. units, however an S.I. version and a U.S. version are available for download just below.

Excel Template – Page 2: Number of Tubes for a Shell and Tube Heat Exchanger
The Excel spreadsheet template at the right is for shell and tube heat exchanger design. This spreadsheet
calculates the number of tubes needed for a specified tube length and diameter. In the spreadsheet templates that can be downloaded below, this page 2 and page 1 from the previous section are both included as part of the same Excel template. Thus the heat exchange area calculated on page 1 can be used for the page 2 calculations.

Excel Template- Alternate Page 2 Length of Pipe for a Double Pipe Heat Exchanger
The Excel spreadsheet template at the left is for double pipe heat exchanger design. This spreadsheet
calculates the length of pipe needed for a double pipe heat exchanger of specified inner pipe diameter and known heat transfer area. The page 1 spreadsheet from the second section in this article is included with this page 2 in the spreadsheet templates that can be downloaded below. The required heat transfer area can thus be taken from the page 1 calculations.
