Part 4/6:
The air is then driven by a fan, crucial for maintaining a low-pressure drop, which aids in the efficiency of the measurements. After passing several components, the air ultimately exits through more baffles and another temperature sensor, providing a second critical temperature rise measurement.
Calibration Process
An essential aspect of the calorimeter's design is the automated calibration process. This involves stepping through a series of incremental power additions, measuring 1 watt, 5 watts, and up to 10 watts, to create a calibration curve. This curve accounts for system inefficiencies and losses, ensuring accurate calculations as long as the airflow conditions remain consistent.
