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 DSST, the split-type air conditioner is a Carrier unit with a capacity of 48,000 BTU, and it has been in service for 8 years.
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 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: 37.28 kWh/day before coating vs 32.82 kWh/day after
- Electricity cost: 5,312 THB/month before coating vs 4,677 THB/month after
- Carbon emissions: 6 tons CO2/year before coating vs 5 tons CO2/year after
- Annual saving: 7,631 THB per year
- ROI: < 2 years
These results equal an energy saving of 11.97%.
Takeaway
The DSST case shows that coating existing split-type air conditioners can lower energy consumption and electricity costs without replacing equipment, even on units that have been running for 8 years.
