How Are Heat Exchangers Calculated and Designed?
Heat exchangers are essential in various industrial systems for efficiently transferring heat from one fluid to another. At BM Process Solutions, we specialize in custom solutions where performance, safety, and energy efficiency are critical. In this article, we explain how heat exchanger calculations & design are approached in industrial environments.
What Are the Key Factors in Heat Exchanger Design?
Before diving into technical calculations, the design process begins by identifying these main parameters:
- Fluid temperatures (inlet/outlet)
- Flow rates and pressure drops
- Heat duty (Q)
- Thermal conductivity and specific heat of fluids
- Material compatibility and fouling factors
These variables influence the choice of heat exchanger type whether it’s shell-and-tube, plate, or compact modular systems.
Core Heat Exchanger Calculations
The performance of a heat exchanger is primarily governed by the following equation:
Q = U × A × ΔTlm
Where:
- Q = Heat transferred (W)
- U = Overall heat transfer coefficient (W/m²·K)
- A = Heat transfer surface area (m²)
- ΔTlm = Log mean temperature difference
Accurate calculation of these values ensures optimal energy recovery, minimal losses, and compliance with industry standards.
For practical design support and thermophysical data, engineers often refer to trusted sources like the Engineering Toolbox.
