[EnergyPlus_Support] Questions of Free cooling chiller example

["miaoworld" <myang04@xxxxxxx>]

I am trying to see the savings by calculating free cooling chiller
example.

In the CSV results, the following two objectives are always zero.  
"FREE COOLER:Free Cooling Heat Exchanger Plant Side Mass Flow
rate[kg/s](TimeStep)" and "FREE COOLER:Free Cooling Heat Exchanger
Condenser Side Mass Flow rate[kg/s](TimeStep)". 

It remains zero no matter how I adjusted the condenser loop setpoint.
 Anyone has similar experience?  
Any suggestions will be appreciated. 

Thanks.

Miao.
