Clean up-Air Aust has finished a job to seal leaks in the air conditioning ductwork at a Queensland Wellness Hospital.
The medical center technique consisted of four AHUs providing air (11,700L/s) to floor and 1st floor regions such as oral health, most cancers treatment, course of action rooms, administration and critical storage. The aim of the task was to stay away from a common solution of removing all ductwork and replacing with new, which would have turned the space into a building website.
“Our goal was to circumvent any disruption to crucial providers currently being delivered to individuals by applying Aeroseal technological know-how to seal the ductwork from the within,” states Job Manager Muni Kumar, “with a target to obtain a 40 per cent reduction of air reduction in the program.”
In advance of that perform could get started, on the other hand, Aeroseal needed Australian-recognised fire safety certification in purchase to be made use of inside Queensland Overall health Hospitals. Clean up-Air duly carried out testing of the products and handed certification for smoke generation in accordance with AS 4254.
The challenge took considerably less than a few weeks to total. Function was carried out right away, with larger sections of ductwork carried out during the weekend, making it possible for units to run all through the daytime and staying away from any downtime for the facility. Kumar suggests that Aeroseal sealant authorized them to only seal the parts where by the duct was leaking, for example, the joins between sections the place the gaskets had failed. This averted a teardown off the complete HVAC program.
In accordance to the task team, before employing Aeroseal, leakage fees had been 4091L/s. Later on they ended up just 263L/s, this means that over-all duct leakage had been minimized by 90 per cent. They say that the facility can now run its HVAC system at a portion of the electric power that was formerly desired, preserving significantly on its electricity fees.
