Energy efficiency requirement for chillers

This standard defines EER and COP of air cooled and water cooled chillers, starting from 2003 (first phase) and 2005 (second phase)

 

water cooled,volume compressor  

• CC <150RT
• first phase: EER 3.50; COP4.07
• second phase: EER 3.83; COP4.45  
• CC ?150RT and ?500RT
• first phase: EER 3.60; COP 4.19
• second phase: EER 4.21; COP 4.90
• CC> 500
• first phase: EER (kcal/h-W)4.00; COP 4.65
• second phase: EER (kcal/h-W)4.73; COP 5.50

water cooled,centrifugal compressor  

• CC <150RT
• first phase:EER (kcal/h-W)4.30; COP 5.00
• second phase: CC EER (kcal/h-W)4.3 COP 5.00
• CC ?150RT and <300RT
• first phase: EER (kcal/h-W)4.77; COP 5.55
• Second phase: EER (kcal/h-W)4.77; COP 5.55
• CC ?300RT
• first phase: EER (kcal/h-W)4.77; COP 5.55
• second phase: EER (kcal/h-W)5.25; COP 6.10

 

air cooled:

• first phase: EER 2.40; COP 2.79
• second phase: EER 2.40; COP 2.79
