Example: Heat Exchanger Material Variation

A cabinet-type heat exchanger (A) is used to extract heat from a sealed industrial automation system. The heat exchanger circulates air throughout the system, and rejects heat to the surroundings. This is useful for sealed systems exposed to harsh environments.

System settings:

1. Flow Variation method = Constant. Flow rate = 71 ft³/min.
2. Heat Transfer Variation method = Heat Exchanger
3. Temperature = 30 °C (the ambient temperature surrounding the system)
4. Heat Capacity = 7 W/K.

The flow rate and heat capacity values were taken from manufacturer-supplied specifications for the device:
