To study the chiller plant room performance /Satheeskumar Rajadran

The chief concern of this project is about to study and develop the chiller plant room performance. The research report provides the findings of the investigations, the performances of the existing Chiller Plant Room 1 (CPR-1) at COMPANY ‘T’. The Chiller No.1 (Trane 450 RT) is operating at 371 RT/450 RT in 80% load cooling load of in average. The Chiller No.1 is operating with 80% of load with efficiency rate of 0.80 kW/RT in average, the chilled water pump is operating with efficiency of 0.48. The condenser water pump is operating with efficiency of 0.78 which is higher than the recommended pump efficiency is 0.7. The cooling tower calculated efficiency for CT-2 is 26.2 USGPM/hp and CT-3 is 22.9 USGPM/hp and rated efficiency shall be more than 38.2 USGPM/hp. The investigations reveal that the Chiller No.1 is not operating in their optimum capacity. The chiller system need to replace with new one. The chilled water pump is operating below efficient level and required to replace or replace with additional variable speed drives. The condenser water pumps are operating efficiently with the optimum capacity. The Cooling towers operations are not efficient and is recommended to operate with a individual cooling tower. Recommendations are provided to improve the CPR-1 system efficiency hence to provide energy savings.
