Heat Exchanger U-Value Calculator
Introduction & Importance
The heat exchanger U-value, or overall heat transfer coefficient, is a crucial parameter in heat exchanger design and operation. It quantifies the rate of heat transfer per unit area and temperature difference. Accurately calculating the U-value ensures efficient heat transfer and energy savings.
How to Use This Calculator
- Select the type of heat exchanger.
- Enter the area, thickness, and conductivity of the heat exchanger material.
- Click the ‘Calculate’ button.
Formula & Methodology
The U-value is calculated using the following formula:
U = 1 / (1/A + t / k + 1/B)
Where:
- A: Area of the heat transfer surface (m²)
- t: Thickness of the material (m)
- k: Thermal conductivity of the material (W/mK)
- B: Overall heat transfer coefficient on the other side (W/m²K)
