HEALTHY CLIMATE AT THE HOSPITAL

Targeted control of the room pressures in negative or positive pressure separate different areas from each other or from their surroundings in regard to air distribution technology. With continuous monitoring of the parameters, there is always an overview of all current states.

• Operating theatre wing
• Care rooms
• Isolation ward
• Labs
• Central sterilisation

Here temperature and humidity control, as well as the reduction of potentially infectious aerosols are particularly important:

• Patient rooms
• Treatment rooms
• Nursery
• Rooms of the normal care
• Examination and recovery rooms
• MRI and CT rooms
• Corridors
• Storage rooms

Particularly in rooms with a lot of public traffic, there is increased sensitivity to the possible transmission of pathogens via the air:

• Reception area
• Occupied zone
• Administration
• Offices
• Pharmacy
• Sales areas
• Kitchen
• Cafeteria

Hygiene is elementary in everyday hospital life – for the protection of visitors, patients and staff.

The new features of our ventilation and air-conditioning systems are therefore specially designed to meet the high requirements for air hygiene and air purification in highly sensitive areas. 

Fire protection in hospitals must ensure rapid evacuation in the event of an incident, as people who cannot save themselves under their own power must be helped here. 

We give functional safety top priority in their fire protection and smoke extract systems.

The top priority in operating rooms is the prevention of post-operative infections (POI). Indoor air technology provides significant assistance in this regard.

Due to the necessary low level of germs, an operating theatre unit is to be classified as room class 1a or 1b according to DIN 1946-4. Contamination of the indoor air by bacteria, viruses and spores must be reduced to a minimum. The removal of anaesthetic vapours, dust and odorous substances also plays an important role here.

A wide variety of aspects are therefore central to the indoor air technology in the operating theatre wing:

• Compliance with the positive air balance (positive pressure) to prevent the penetration of possible contamination from adjacent rooms

• Maximum relative room humidity below 50 % r.h.

• Fresh air flow rate between 800 - 1200 m³/h to limit the danger posed by anaesthetic gases

• Freely selectable temperatures between 18 and 24°C (possibly up to 27°C in paediatric surgery)

In order to guarantee these points, indoor air conditioning systems must offer at least 2 filter stages that constantly draw in, humidify and dehumidify, filter and temper the indoor air according to the requirements

Standard in the classic operating theatre are tissue ceilings that ensure a so-called low-turbulence displacement flow (TAV). In terms of air technology, operating theatre units are similar to Clean rooms.

Let our industry experts advise you on your individual options.

When highly infectious patients need to be cared for or persons with severe immunosuppression need to be protected, nursing rooms and intensive care units also belong to the room category of critical areas. 

As a result, the requirements for infection control and hygiene are also increasing. The ventilation and air-conditioning system contributes to the protection of patients and staff by cleaning the room and supply air.

What is important in critical ICU patient care rooms includes, among other things:

• Mechanical ventilation with particle-filtered supply air and/or extract air
   
• The use of passive or active airlocks
   
• Static pressure maintenance in positive or negative pressure (aseptic/septic)
   

If these important factors have been taken into consideration, the staff is optimally protected from the point of view of ventilation and air conditioning and there are good conditions for an ideal recovery process for the patients. 

We will be happy to advise you on designing, equipping or modernising your premises with our innovative and flexible solutions. 

Everyday laboratory work involves working with substances that are hazardous to health or dangerous in order to produce or research new medicines. 

This requires special measures to protect employees, the environment and products. In addition, a comfortable working environment with high indoor air quality and a pleasant climate must be created. 

Here, the ventilation system plays a decisive role by regulating both the supply air and the removal of contaminants.

To achieve the legal protection goals, the following factors must be taken into consideration in the air management system:

• Balancing the volume flow rates of room supply and extract air, as well as technical extract air
   
• Dissipation of thermal loads
   
• Regulation of the required room pressures
   
• Reduction of airborne particles, if applicable
   

If all these aspects are fulfilled under the relevant requirements, the protection of employees is also guaranteed.

With bespoke solutions, TROX develops new systems in all areas related to research facilities and laboratories. Profit from our extensive know-how. 

Special care and hygiene are required within the sterilisation processes. Proper cleaning of surgical instruments has a direct influence on the postoperative infection rate and therefore contributes to the patient's rapid recovery in the ideal case. 

In this area, ventilation and air-conditioning systems must meet the highest requirements to protect people and technology. Unlike in unclean areas, there must be a positive pressure here. 

The following points are decisive for the control of the external volume flow:

• Thermal loads
   
• Humidity
   
• Hazardous substance exposure
   
• No. of people
   

Our flexible and bespoke solutions are used wherever the highest demands are placed on air hygiene and indoor air conditions:

You too can find the right solution together with us. 

The central emergency room (ER) is a primary point of contact for patients in need of acute care. Lives are saved here every day.

While the number of cases has risen steadily in recent years (source: Ärzteblatt), many people have concerns about visiting an ER because of Sars-Cov-19. The reason: patients who stay there are often already ill –  and thus may carry potentially dangerous germs and viruses. Their breathing alone produces aerosols that transport the corresponding pathogens into the ambient air and can lead to the infection of other people. This is precisely where a correspondingly great challenge lies for air management. 

In addition, the indoor climate in this area of the hospital is characterised by interior rooms, numerous medical devices with high heat loads and often an insufficient air supply from outside. In the warmer months, the room climate in the ER is also under particular strain due to a large number of patients. In winter, on the other hand, draughts and unwanted cold must be prevented indoors.

The following is therefore vital for a pleasant room atmosphere: 

• A sufficient supply of outdoor air 
  
  
• Temperature and humidity control 
  
  
• Maintenance of air quality through filtration and airflow
   
• Airlocks in the passageway for the patients arriving in the prone position 
  
  

If these criteria are met, the indoor climate in this usually hectic zone of the hospital contributes positively to the recovery of the patients, as well as creating a pleasant working atmosphere.

Together with us, find the best solution for your emergency room in terms of ventilation and air conditioning technology

In rooms where patients spend longer periods of time, high air quality is not only pleasant, but also beneficial to health. Bad odours and stagnant or stale air are noticeable and make visitors and staff uncomfortable.

In this context, precisely coordinated ventilation and air conditioning can even contribute to a faster recovery and thus accelerated discharge of patients from hospital.

Furthermore, clean air has a positive effect on the working atmosphere of healthcare professionals and thus brings a potential increase in productivity. Considering these two factors, a well thought-out indoor air concept contributes greatly to efficient hospital operations. For this reason, individually suitable indoor air solutions are particularly important in sensitive areas such as patient rooms, examination rooms, nursing wards and recovery rooms.

The tasks of a corresponding system essentially consist of the following points:

• Turbulence-free air exchange
  
  
• Humidity control
  
  
• Fresh air volume flow rate according to the specific room use
  
  
• Room temperature between 22°C and 26°C

With suitable elements such as HEPA filters, the risk of infections caused by aerosols is also minimised.

Let our industry experts advise you on the most efficient ways to help your patients breathe easier.

Storage rooms, such as those used to stock medicines, are by no means exclusive to hospitals, but can also be found in pharmacies, doctors' surgeries and nursing homes.

Most preparations can be stored at room temperature between 15°C and 25°C without risking loss of efficacy. However, there are also substances that require refrigeration, such as insulin, vaccines or certain eye drops, which require permanently cool storage (between 2°C and 8°C)

Moreover, it is not only medicines that require appropriately safe and air-conditioned areas for storage. With regard to rising temperatures in summer and condensation, for example, the topic of indoor air takes on an important role with regard to textiles, among other things. 

In addition, occupational health safety aspects must be observed, especially in disinfectant and solvent storage facilities. 

The following points are of central importance for the indoor air, depending on the stored items:

• Constant room
  
  
• Humidity control
  
  
• Protection against light
  
  

With TROX, you can store your medicines and other important products optimally and safely, even when outside temperatures fluctuate.

"Please take a seat in our waiting room" is often heard in medical facilities. To protect the patients, various disinfection facilities are placed within corresponding zones. However, they cannot replace an air washer with a special HEPA filter. This removes harmful germs and viruses directly from the air that surrounds you.

It is possible to install a ceiling filter or to use a floor unit in smaller rooms. Here, observing not only the hygiene standards, but also the comfort requirements of patients and staff, is vital. Central aspects for your reception area include:

• Filtration of fine dust, house dust, allergens and other contaminants
   
• Reduction of the aerosol concentration
   
• Temperature control
   
• Prevention of draughts
   
• Protection of privacy and therefore no room air change via door undercuts (DIN 4109)
   
• Pressure-neutral ventilation operation for compliance with the sound insulation standard
   

Medical building complexes include not only treatment, care and waiting areas, but also offices and administrative wings. 

For the employees working there, the best possible indoor air quality is essential. The high demand for office air exists not only in terms of the increased likelihood of infection in hospitals, but also in terms of productivity and satisfaction. Simple Plexiglas walls or occasional ventilation are not sufficient within the scope of a comprehensive hygiene concept to achieve the necessary standards.

The ventilation and air conditioning strategy for offices depends on many factors. 

• Architecture and building type
   
• Location
   
• Room volumes and layout
   
• Occupancy and building type must be taken into consideration. 
   

Our know-how and the wide range of ventilation and air-conditioning systems, devices and components enable us to respond to your individual requirements.

Professional advice in a hospital is not only provided by competent doctors and nurses. Many facilities have their own pharmacy where necessary medication can be obtained directly on site.

A pleasant atmosphere with clean and well-tempered air contributes to customer satisfaction and staff productivity in addition to the comfort aspect.

In light of this, ventilation and air conditioning systems have to adapt to constantly changing environmental conditions while continuing to run efficiently.

Within the hygiene management for your pharmacy, consider the effectiveness of air filters and offer your visitors a safe and pleasant shopping experience.

The health of patients is the absolute focus in medical facilities. In addition to accurate medical treatment, physical well-being is also important. 
 

In the kitchen and cafeteria, however, not only tasty dishes are created, but also odours that must be effectively kept away from the rest of the building. 

Working within an area where food such as hot fats is handled also requires a high level of hygiene and safety. 

Not to be forgotten are also the high thermal loads that have to be dissipated as efficiently as possible.
