Observations :

1. Chiller System is one of the major loads in the factory. Both Chillers contribute app. 30-35%
in the total energy consumption (At present ambient conditions). It is obvious that this shall go
up with increasing ambient temperature.

2. Specific Energy Consumption of the chillers is above 1.30 KW/TR. Both chillers are operating
at partial loading around 50%.

3. Delta T (Temperature difference across evaporator is 1.2°C which is very poor and shall be
raised upto 3-4 °C.
