[EnergyPlus_Support] the simulation of the chiller

["llyymmff" <liyuemingff@xxxxxxx>]

Hi, 
I have a question when I do the simulation of the chiller, could you 
please help me?
Why is there some temperature difference between the chiller condenser 
and the cooling tower?
For example, the outlet temperature of the chiller condenser does not 
equal the inlet temperature of the cooling tower. 
I don't know why. Should the outlet water temperature of the chiller 
condenser be the same as the inlet water temperature of the cooling 
tower (when these two equipements are connected)? The document explains 
the temperature difference between the inlet of the condenser and the 
outlet of the cooling tower, but I don't find the reason for the 
difference between the outlet of condenser and the inlet of cooling 
tower? 
I observed that the difference be decided by the water flow rate. when 
the water flow rate is larger the temperature difference is smaller. 
I cannot explain it, please help me.
Thank you very much!
Best regards!
