Your chiller
Scales the estimate across all identical chillers.
Enter the chiller's rated cooling capacity in refrigeration tons (RT). Estimated electrical input is calculated using the kW/RT factor in Advanced settings.
Applied as an estimated average-load factor to energy and carbon calculations.
Default 18%, based on the sponge-ball tube-cleaning study listed in the references. This is the estimated reduction in chiller electricity consumption, not total building energy consumption.
Advanced settings
Converts cooling capacity (RT) into estimated electrical input (kW). The default 0.934 kW/RT is an illustrative reference from the cited performance comparison; replace it with the chiller's measured or specified value where available.
Used only for the cost estimate. Enter your own rate.
Water-use comparison assumptions
Enter the water used or discharged specifically for tube cleaning. Use comparable boundaries and units for each method. These figures do not include normal cooling-tower makeup water.
ATCS default is 0 additional water discharged for the tube-cleaning process, reflecting its recirculating, no-routine-water-discharge design. Confirm the actual installation boundary and site conditions before using this as a reported result.
With HydroBall ATCS you save
| Manual cleaning | 0 L/year |
| Other tube-cleaning systems | 0 L/year |
| HydroBall ATCS | 0 L/year |
Savings are calculated as the comparison method's annual water use minus HydroBall ATCS's annual additional water use. Negative values mean ATCS uses more water under the assumptions entered.
How it's worked out
| Estimated electricity use per day (RT × kW/RT × H × chillers × utilization) | |
| Estimated CO₂e per day (electricity × grid factor) | |
| Estimated CO₂e per year (per day × operating days) | |
| Chiller-specific electricity saved per year (electricity × savings %) | |
| Estimated electrical input (RT × kW/RT) | |
| Annual water used for manual cleaning | |
| Annual water used for other tube-cleaning systems | |
| Annual additional water used or discharged by ATCS |
