Q1. Chiller efficiency
Ans. 
Chiller efficiency is a measure of how well a chiller unit is able to cool a space while using the least amount of energy.
• Chiller efficiency is typically measured by the Coefficient of Performance (COP), which is the ratio of cooling output to energy input.

• Regular maintenance and cleaning of chiller components can improve efficiency.

• Upgrading to a more energy-efficient chiller model can also increase efficiency.

• Proper ...read more
