Medical Air System Replacement |
|
| OVERVIEW |
|
- Pediatric and obstetric health care organization dedicated to patient care, education and research.
- 240 licensed beds, 762 medical staff.
- Over 11,000 admissions and 91,908 clinic visits per year.
- Located on Stanford University property in Palo Alto.
|
|
| CHALLENGES |
|
- An existing triplex 50 HP medical air system was reliable but inefficient.
- AES monitors found actual peak demand at 55 PSIG was 63 CFS vs. the theoretically calculated 170 CFM.
- Existing units consumed 12 GBP water, or 105,120 gallons per year.
- Hospital engineers manually rotated the 50 HP medical air compressors every eight hours.
|
|
| SOLUTIONS |
|
- AES recommended and installed a quadraplex 20 HP air-cooled, oil-less reciprocating compressor system.
- Horsepower required was reduced from 150 HP to 80 HP.
- Water consumption was eliminated.
- The quadraplex 20 HP system includes automatic controls to operate the exact number of units needed to satisfy medical air demands (no more manual rotation).
- A dual tower desicant air-drying system including CO and dew point monitoring completes this state-of-the-art operation installation.
|
|
| BENEFITS |
|
- Reduced electric usage by 20%.
- Elimination of water usage.
- Electricity and water savings alone resulted in a two-year payback on the hospital's investment.
- The changes brought Lucille Salter Packard Children's Hospital's medical air system into compliance with the most current NFPA99
- requirements.
