Adsorption Chiller Comparison
Why Adsorption is a Better Choice ?
Adsorption versus Absorption Comparison
| Factors | Adsorption Chillers | Absorption Chillers |
| Life Expectancy | Greater than 25 Years | 7 to 9 Years |
| Maintenance | Negligible Maintenance | Require High Maintenance |
| Regeneration Temperature (Hot Water) |
Down to 50°C (122°F) | Shuts down at 82°C (180°F), Needs Back-up Heater |
| Desiccant Used | Silica Gel (Inert) | Lithium Bromide (Highly Corrosive) |
| Replacement Requirements (Periodic Maintenance) |
Not Required | Heat Exchangers, Boilers, Absorbent Replacement Required |
Adsorption versus Mechanical Chiller Comparison
| Attribute | Adsorption Chiller | Mechanical Chiller |
| Sound Pressure Level | Very low <50 db (A) | Loud > 80db (A) |
| Operating Cost | Negligible | High |
| Maintenance | Virtually none | Seasonal maintenance required. Annual oil analysis Replace oil every 5 years Periodic tear down and rebuild required Replacement of bearings every 15 years |
| Chemistry | Municipal water and special silica gel-S2 |
HFC and HCFC refrigerant with synthetic oils 2 |
| Energy Requirements | Hot water: 50°C to 93°C (122°F to 200°F) |
Electricity 230/415 – 3Ph – 50Hz 460 – 3Ph – 60Hz 240 – 3Ph – 60Hz |
| Cooling Water Requirement |
Preferably < 30°C to 10°C (85°F to 50°F) Lower temperatures increase capacity of the system |
30°C to 18°C (85°F to 65°F) minimum temperature – unstable at low temperatures |
| End-of-life | No special disposal requirements |
Certified technician required to reclaim all refrigerant for release to the atmosphere |
The Bry-Air Adsorption Chiller is based on an innovative green technology, and is the first of its kind in India, and is being manufactured in India.
