Background
Air conditioning and chiller systems are among the largest electricity users on an industrial site. Over time, condenser coils lose heat transfer efficiency, which forces compressors to work harder and increases energy consumption. At Erawan Agricultural Chemicals, the split-type air conditioner is a Daikin unit with a capacity of 80,000 BTU.
The solution: THERMAL-XR®
THERMAL-XR® is a graphene-enhanced coating from Graphene Manufacturing Group (GMG), designed to deliver superior heat transfer and protection for heat exchanger coils. The coating was spray-applied to the condenser coils of the split-type air conditioner, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 59.76 kWh/day before coating vs 44.07 kWh/day after
- Electricity cost: 8,180 THB/month before coating vs 6,032 THB/month after
- Carbon emissions: 10 tons CO2/year before coating vs 7 tons CO2/year after
- Annual saving: 25,766 THB per year
- ROI: < 1 year
These results equal an energy saving of 26.25%.
Takeaway
The Erawan Agricultural Chemicals case shows that coating existing split-type air conditioners can cut energy consumption by more than a quarter without replacing equipment, paying for itself in under a year.
