St.Vincent's Hospital


Super-Efficient Dehumidfying Eliminates Costly Reheating of Water to Win the Battle Against Humidity

A New Wing Won’t Fly Without New Thinking.

St.Vincent’s is a 338-bed hospital located just outside of Birmingham, Alabama, known for its community involvement and commitment to caring for the poor and vulnerable. Alabama is known for its mix of mercilessly high heat and oppressively high humidity. This creates a very large problem for hospitals like St. Vincent’s with its rooftop-mounted HVAC system. These systems cannot independently control temperature and humidity, so when outdoor air is used it creates more indoor humidity, prompting even more expensive lowering of thermostats. To combat this, chilled air is often reheated to rid it of humidity but this is also an expensive process. So when St. Vincent’s wanted to open a new orthopedic wing, they needed a strategy to fight this problem. After all, a hospital devoted to those with limited means has limits of its own.

Not Just a New System, A Whole New Solution.

Luckily for St. Vincent’s, Trane is in front of the curve when it comes to this problem. Trane has developed a whole new technology to handle cooling in high-humidity environments – the CDQ (Cool, Dry, Quiet) desiccant system. The CDQ application eliminates the need for reheating water to achieve proper humidity control. It employs an integrated active desiccant wheel that captures water vapor from the cooling coil. The wheel then slowly rotates to be regenerated by return or mixed air upstream of the coil—using no additional heat. Or, to put it more simply, at St. Vincent’s, operating rooms can stay at 62 F and 50 percent relative humidity—even during Birmingham summers, without incurring outrageous energy costs.

What Started As a Practical Idea Became a Product of the Year.

St. Vincent’s new HVAC system, which combines Trane’s M-Series Climate Changer™ air handler with the CDQ™ system has not only done the job, it has turned out to be an award-winning product. “Trane stepped up to the plate and provided an economic, timely and well-designed product that exceeded everyone’s expectations,” according to Al Mauro of Hardy Corporation, the mechanical contractors on the project. And the buzz extended far beyond Birmingham. The CDQ desiccant system was the recipient of the 2006 Frost & Sullivan Product Innovation of the Year Award presented to the companies that achieve excellence in new products and technologies. This story is proof that award-winning ideas can happen on any job—but when they happen on a job like St. Vincent’s, it’s especially gratifying.
