Example: Heat input/Extraction Rate Material Variation

A heat exchanger device (A) simulates the effect of a CRAC (B) unit in a data center. The objective is to remove a specific amount of heat.

We've modeled the heat exchanger device as a rectangular block within the CRAC. Also, the CRAC unit part is suppressed (not meshed). For more about modeling CRAC units, click here.

System settings:

1. Flow Variation method = Constant. Flow rate = 5500 ft³/min.
2. Heat Transfer Variation method = Heat Input/Extraction Rate
3. Heat Input/Extraction Rate = -51200 BTU/hr. (A negative value indicates that heat is removed from the working fluid.)

The flow rate and heat input/extraction rate were taken from manufacturer-supplied data:
