Appendix B: Reference Data Table

The following tables show the selected important variables for the IMAC systems at all 

test conditions of the steady state tests. It should be noted that:

1. The final reported system capacity is determined by using the average of airside 

Qair and chamber side Qch balances of the evaporator all but the points to be 

mentioned in the following two cases. 

2. For 25/15oC ambient temperature, low load points had a glycol supply to the 

evaporator chamber that was not measured. Therefore, no chamber balance is 

available to these points. In this case, the system capacity uses only the airside 

balance and the number for Qair is displayed in red within the table.

3. For low evaporator air flow, only one nozzle was used to measure airflow rate. 

For these points, only Ten2 is available to display.

4. There are two sets of data: one for Ten = 10 °C setting and the other for Ten 

matching SAE ARCRP phase II.
