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

Water cooled systems are generally more efficient than air cooled systems due to higher heat transfer capabilities.

• Water has higher heat transfer capabilities compared to air

• Water cooled systems can maintain more consistent temperatures

• Water cooled systems are typically used in high performance applications such as data centers and industrial machinery

Duct velocity can be improved by increasing the fan speed or reducing the duct size.

• Increase the fan speed to increase the air velocity in the duct.

• Reduce the duct size to increase the air velocity.
