With experience from over 300 installations in hospital and healthcare facilities, Fläkt Woods is the safe choice for air management systems. Our solutions provide ultimate function for the specific demands of, for example an operating theatre, whilst meeting the highest standards of energy efficiency to deliver low life-cycle costs for the entire building.

HVAC systems for hospital and healthcare facilities have special requirements because of the inherent nature of their functions and the unique susceptibility of patients to infection. In perhaps no other application is the HVAC system a more important and integral, component of the building’s processes.


Specific Healthcare demands
Where the healthcare building has specific demands, Fläkt Woods has solutions. Our product portfolio includes equipment and systems that meet the challenging requirements for air cleaning, leakage standards and infection control. Effective HVAC systems provide a comfortable environment, including temperature, air quality, humidity, odour and noise. It therefore affects not only the conditions of the hospital staff and visitors, it also facilitates good conditions for the patients’ healing processes – comfortable patients heal faster.

Cleaning and maintenance
Maintenance operations such as cleaning are always a major issue with any plant, mostly because of functionality issues. Within the healthcare sector requirements are even higher due to the stringent hygienic demands. Every component within our HVAC systems has been designed to facilitate visual inspection, along with easy and effective cleanability.

Certificates and standards
Our systems have been designed and developed in accordance with the most stringent Hygiene standards in Europe. As an example, our eQ Plus® AHU received the ILH certificate delivered by the German Institute for Hygienic Air. Fläkt Woods AHU’s are well designed according to the German standard VDI 6022 and the Swiss SWKI Richtlinie VA104-04 (04/2006). This guarantees that maintenance will be easy and effective and that the materials used are microbiologically inert. We also strive to extend the use of recyclable materials and operate in accordance with ISO 14001.


 

The operation room must be an ultra clean room to protect the patient against infection. The surgery table is the most critical zone of the room. The contamination must be controlled below specified levels. The ceiling filtration system must also have the ability to clean the room rapidly between operations, in order to avoid cross contamination. Each operating room must have a risk analysis to estimate the level of protection of this room, including: Pathogenicity of all the agents present in the operating room, possible consequences of an exposure, methods of transmission, duration of operations, number of staff, etc. These parameters will define the requirements of the operating room:

  • Dimensions
  • Quality of diffusion
  • Supply air volume
  • etc

Challenges
Operation theatre must be scrupulously clean to protect the patient:

  • Control of contamination, recognising the zones of focus around the operating table
  • Efficient anaesthetic gas removal
  • Fast particle decontamination
  • Fast to clean and readjust between operations
  • Comfort working conditions for the surgical staff
  • Uninterrupted working for the surgical team

1. Isolating Room

Isolation bedrooms may generally be classified into two types: Airborne Infectious Isolation Rooms for patients having an airborne, communicable disease and Protective Environment Rooms for patients suffering from weakened immune systems who require protection against infectious airborne agents.

Challenges
These rooms have two ventilation features in common: negative orpositive air pressure relative to all adjoining spaces, and an air distribution pattern within the room which facilitates airborne infection control. The flow pattern should be designed to protect the patient and reduce the exposure of uninfected visitors to the room.

2. Patient Room

Research has shown that a comfortable patient will recover faster. The indoor climate is therefore crucial.

Challenges
The air supplied into the patient room area must be hygienic to avoid any airborne particle conta-mination. The patient will also require a comfortable temperature, without noise or draughts.
