STORIES WORTH TALKING ABOUT
Chiller Plant Case
- Two 6-yr old chillers under manufacturer service contract. Chiller plant well-equipped with water, temperature and electricity meters but efficiency problems were not identified.
- Baseline condition: KW/ton > 0.9
- After energy efficiency improvements: KW/ton <0.7, resulting in
- < 20% energy savings
- Green Mark recertification achieved
- 198,000 KWh per year saved corresponds to SGD 24,000 only in annual energy savings without including maintanence savings.
ClimaCheck, being the core technology, was applied to find
- Expansion value issues
- Inadequate Refrigerant Charge
- Unbalanced water flows
- Water flowmeter with caliberation problems.
After optimization, the following benefits were achieved
- Less energy consumption
- Better reliability
- Improvement plant for futher savings.
