| Optimum ventilation system required for hospital university  Under a contract working for YIT Corporation, Fläkt Woods is providing ventilation equipment for Sweden's world renowned university teaching hospital at Umeå University. After initial discussions with consultants WSP Group, who are responsible for designing the new operating rooms at the thoracic heart surgery clinic within the University, and in-depth discussions with the hospital staff, it was decided that Fläkt Wood's innovative DIF-OT air diffusion system would be used in the operation rooms. The DIF-OT is a hygienic diffusion ventilation system, which was chosen to help to reduce the risk of airborne contamination in the operation rooms. The system creates a unique air movement with 3 differentiated air velocities from the centre of the ceiling as opposed to the outside. Thanks to this ability it helps to significantly reduce the number of air borne contaminants. It is a very good complement to other hygienic actions from the surgical staff and together they aid speedier patient recovery. There is strong evidence to support the association between ventilation, air movement in buildings, and the transmission/spread of infectious diseases. It is critical therefore that air must be controlled to limit the risk. The ventilation and the filtration systems have to provide ultra-clean air in order to keep the patients alive and healthy. Once installed the new system will diffuse the air, either by unidirectional airflow or laminar airflow for the highest risk room (where ISO5 class is required) and turbulent diffusion for the lowest risk rooms (where ISO7 is required). The laminar airflow prevents contaminated air from entering the operating area in order to achieve ISO5 class under the ceiling. The clean supply air pushes the contaminated air outside the area which must be cleaned. The new system is encased in stainless steel and incorporates HEPA filters. In addition to the DIF-OT air diffusion system, Fläkt Wood's contract also includes supplying units for a complete upgrade to the university's air handling system, and this comprises the Company's award winning eQ air handling units. The eQ range from Fläkt Woods is a modern, highly adaptable air handling unit, offering a selection of state-of-the-art features; intelligent controls, energy efficient components and a flexible design. By combining all these developments into one system, Fläkt Woods has achieved the best energy solutions possible. This strategy requires that the systems and individual components are designed together. Fläkt Woods is also supplying air handling units from their EU range. The EU modular air handling unit gives total flexibility with its wide range of functions and options providing the optimum air handling solutions possible. The supply and exhaust units feature run-around coil recovery systems, heating, integrated local cooling and integrated local controls with connection to a BMS system A critical factor in specific areas is comfort cooling, with as little air movement as possible, a high degree of energy efficiency and low draught displacement. Commenting on the contract win, Bosse Lindström, district sales manager at Fläkt Woods in Umeå said; "This new thermal environment will be comfortable for all the staff and they will now be able to work without additional constraints caused by the ventilation and filtration system. One challenge on the contract has been creating bespoke units that will fit within the tight confines of the hospital operating theatre and perform to a very high specification. By exchanging the old ventilation system with differential flow velocities laminar airflow, together with professional hygienic awareness of the hospital staff, we will considerably reduce the air borne contaminates in the operating rooms. This will give improved patient safety and save a great deal of money as a result of increased patient recovery times." write your comments about the article :: © 2012 Construction News :: home page |
