Ventilation solutions for hospitals

In hospital ventilation, low levels of infectious substances are superior to the energy targets. Preventing the spread of infection is an important task for ventilation in hospital environments. At Lindinvent we know the set requirements for these environments and how to approach them.

Safe ventilation

Low levels of infectious substances are superior to the energy targets when ventilating hospitals. Preventing the spread of infection is an important task for ventilation in hospitals and healthcare environments. In certain types of care, low levels of airborne contaminants are crucial to the result, for example in transplants and burn injuries. It is crucial that hospital ventilation really works properly and as it should. This sometimes creates significant disruptions to the daly business when, in worst case scenario, operations are forced to be postponed for days due to ventilation malfunction. This shouldn't have to happen.

Who is responsible?

The responsibility for preventing the spread of infection lies with the health care system, but the practical responsibility for function and construction of the ventilation lies in the hands of those responsible for the property. This shared responsibility can put caregivers in difficult situations as they often don't know how ventilation should work. If it turns out that the ventilation spreads airborne contamination, then the health operations managers are reported to the National Board of Health. Hospital care is therefore very much in the hands of the technology.

Collaboration for greater understanding

In order to achieve the desired air purity in hospital environments, it is important that the various actors cooperate and understand each other, partly for the care side to be able to make demands on the ventilation systems and to know what to expect, and partly for property and technology managers to understand what hospital care environments require and implement the suitable solution. This is something that can be a bit difficult to achieve when many players are involved. Some property owners outsource the ventilation operation to private companies, which makes communication between hospitals and property managers even more difficult.

We have the knowledge

The distance between caregivers and the property owner can also be an obstacle when designing ventilation. In some cases it may mean that incredibly advanced ventilation is prescribed everywhere due to not knowing how to apply ventilaton in care environments. At Lindinvent we know the requirements since we have years of experience working with different care environments.

Set Requirements

The Care Hygiene Association defines its requirements in the unit cfu/kbm (the amount of bacteria per cubic meter) based on what is justified in preventing the spread of infection, a set requirement. A maximum of 10 cfu/m3 is the level recommended by the association in rooms for surgery and the most sensitive operations; joint plastic surgery and vessel transplants. Those technically designing the ventilation have to put the health of the patients first. Therefore, energy saving becomes subordinate to the medical requirements of the Health Care Act and the Infection Protection Act to prevent the spread of infections. However, control for energy measures can be implemented in other areas that are not subject to these requirements. Our solution is optimal as you can optimise and set different conditions for different zones via LINDINTELL and LINDSPECT.

Energy saving measures where allowed 

If a room is empty (and not controlled by the requirements to avoid spreading of infectious diseases) the ventilation should be shut off to save energy. In the same way, a full building requires a lot of ventilation. The number of people actually in the property is therefore extremely important. It is also extremely important in determining the total cooling and heating capacity that must be available. Demand control is of course dependent on this level of occupancy.

We therefore have in-built occupancy detectors in each diffuser so that we get really good information about this level of occupancy both on a room level and on an aggregate level for the whole property.
