Is it feasible that in CHW Cooling coil, design coil load is much greater than Nominal capacity?

Hi,

I have attached the OSM file and the eplus output file. I don't understand where I have made mistake.

The cooling coil design load is 2837396 W whereas, its nominal capacity is 1775951 W
The cooling tower has less wattage (2682661 W) than electric chiller (2837348 W).
The comfort parameter is never met through out the year.

Please help.

Regards, Smruti

I have rectified the problem my self.

The problem was related to the sizing factors. I gave a global sizing factor of 1.25 for cooling equipment as well as 1.25 for chiller. This made the chiller having more wattage than the cooling tower.
The comfort parameters are satisfied after I changed the default setting (like loop exit temperature and loop temperature difference)about condenser and chiller loops in open studio.
