MRF Tyres Quality Engineer Interview Questions and Answers

Approach in chiller refers to the method or strategy used to control the temperature of the chilled water.

• Approach in chiller is the temperature difference between the leaving chilled water and the entering chilled water.

• A smaller approach indicates better chiller performance.

• Approach can be controlled by adjusting the flow rate of the chilled water or the setpoint of the chiller.

• Monitoring approach is important to ens

Factors affecting cooling tower efficiency include water quality, air flow, temperature differentials, and fouling.

• Water quality - Impurities in water can reduce heat transfer efficiency.

• Air flow - Proper air flow is essential for heat exchange.

• Temperature differentials - Larger differentials between hot and cold water improve efficiency.

• Fouling - Buildup of scale or debris can decrease efficiency.
