Hospitals face ever-increasing scrutiny from the Joint Commission on Accreditation of Healthcare Organizations (JCAHO). We’re finding that enforcement of healthcare related critical space environmental standards are accelerating the capital planning timeline of HVAC upgrades, with a specific emphasis on air handling unit replacements. Air handler replacements are rarely cheap and never easy. Modern, efficient air handling units don’t often fit into the same dimensional boxes as their older predecessors. Whole unit replacements can be surprisingly expensive because large swaths of mechanical room components need to be moved out of the way or replaced to make room for the new, larger machinery. The impact potentially can result in compromised schedules, disrupted operations and magnified costs. Pardon the cliché, but effective hospital air handler upgrades often require outside-the-box thinking. However, when it comes to the pre-existing large scale custom-built air handling units in most hospitals, it’s what’s inside-the-box that usually needs to be replaced.

The box itself — the structural frame and outer skin — can often last for generations to come. Such was the case for one of our long-time hospital clients. Faced with repeated component failure and performance deterioration on 40-year old systems, this hospital recently undertook an aggressive air handling unit upgrade program. By re-building the air handling systems from the inside out, rather than simply replacing them, we cut the planned capital cost in half and minimized operational disruptions, all while helping them to meet present day environmental and redundancy standards.information about air handling unit Specifically, we performed the following work:ac unit fix This design-build approach demanded trust and cooperation between the hospital staff and our engineers. ac/heating units for mobile homes

It required extensive upfront time, creativity and diligence. However, the pay-off for our client was huge, with improved environmental conditions and enhanced system redundancy. From the owner’s perspective, the process of doing the upgrades went undetected by staff and patients; cost hundreds of thousands of dollars less than a traditional replacement program; and eliminated a difficult capital need for another generation. The key to unusual success was collaboration between administrators, maintenance staff, engineers, service technicians / contractors, and vendors. In this case it was a sole-source design-build delivery model. But any design-construction delivery model that genuinely enhances collaboration between all stakeholders will have better outcomes than those that perpetuate traditional divisive behavior.® For 75 years the Governair brand has been an industry leader in highly-customizable commercial and industrial air handlers. Governair's philosophy of delivering elite custom quality without the preventative costs generally associated with custom services results in industry leading value for markets of every scale.

power HVAC system for world's largest geothermal hospitalSingle-flow air handling unit / horizontal / hospital Single-flow air handling unit / horizontal / hospital An operating theatre is provided with preconditioned air by a central air handling unit (AHU). Nowadays, most hospital ventilation systems operate with a mixture of fresh and recirculation air. For operating theatres or minor surgery rooms to be upgraded or renovated, recirculation modules are an excellent alternative. Because many older facilities have insufficient space for bigger AHU’s and ducts etc, the recirculation module can be installed in either the ceiling (Optivent) or the wall (Optiwall). Here, the recirculation module will supply the recirculation air and the existing or new AHU will supply the fresh air portion. Recirculation modules consist of three parts: Plinth – where the height of the unit will be adjusted and fixed Suction Chamber with installed Fluff Separator, Fine Dust Filter (F7), Control box as well as cooling battery

The hospital is a 566-bed facility located in downtown Madison.

Recognized as a national leader in surgical specialties, UW Hospital looked for that same quality when the time came to replace its Air Handling Unit responsible for Surgical Operating Rooms 1-6. Masters Building Solutions teamed with UW Hospital to provide AHU-37A, a custom built Haakon unit. Haakon was chosen for AHU-37A due to several highly custom features. The unit was required to have its supply and return air connections located on the same end of the unit. In order to accomplish this, AHU-37A was designed in a 'U' shape with a 9-foot service corridor down its center. This corridor provides access to each AHU section as well as a place for the piping, specialties, and controls. The corridor also contains a 3-foot by 3-foot access hatch allowing service personnel admittance to the space below the unit where the valves, traps, and condensate piping are located. To help address snow intake issues during Wisconsin winters, the outdoor air intake section was custom designed.

Custom Haakon storm louvers, drain pans, and custom intake ductwork within the air handling unit will keep the snow out. Quad Fans were applied to provide optimal efficiency, redundancy and sound. This technology is known as the "Green Fan Wall." To further boost fan efficiency gain and to add a static regain component, Aero Acoustic Diffusers were included on all fans. Up to 80% fan efficiencies are obtainable with this fan arrangement. Coupled with premium efficient motors, this is the most efficient fan system available. The supply air passes thru one of the most advanced carbon filtration systems on the market, thus ensuring the purity of the air sent to the operating rooms. AHU-37A arrived at the job site on four semi-trailers; individually shrink wrapped to maintain the cleanliness of the product during transport. Each section was lifted to the roof and assembled in one day. Air leakage testing was completed three days later and the unit passed easily. HEPA Filters have been tested and passed the hospital's stringent requirements for leakage.
