Outline of GHG Mitigation Activity
Air-conditioning is indispensable in maintaining the quality control of the product and working environment in the Tire Manufacturing Factory. The air-conditioning system operates long time and causes large power consumption. An introduction of the high efficiency Centrifugal Chiller realizes energy saving of the air-conditioning and reduces CO2 emissions.
The Centrifugal Chiller adopts a high-performance compressor (two stage compressor), which miniaturizes the compressor and reduces electric power consumption. In addition, the chiller adopts refrigerant HFC245fa which has higher cycle performance and energy efficiency than conventional refrigerant HFC134a.
Expected GHG Emission Reductions
Reference Emissions = EF×EC×（COPPJ／COPRE）
= 3,491.58 （tCO2）
Project Emissions = EF×EC
= 3,106.22 （tCO2）
Emission reductions = RE－PE = 385 （tCO2）
EF ：CO2 Emission factor =0.5113（tCO2／MWh）
EC ：Power consumption of project chiller （MWh）
COPPJ ： COP of project chiller
COPRE ： COP of reference chiller
