VDI6022 hygiene inspection from Ulm  

The profluid hygiene inspection is worthwhile

Because there's air to live in

  With each breath we consume air, which varies in composition depending on the location. Besides 21% oxygen, 78% nitrogen, 0.04% carbon dioxide and approx. 0.9% argon, there are many other components in the air we breathe. For example, solid and liquid particles (aerosols), water, dust and other biological particles such as fungi, spores, pollen, germs and other microorganisms. The statement "air is not equal to air" is therefore absolutely correct. 


Air quality has a decisive influence on our health and performance. By designing their living space almost entirely themselves, people do influence the air aswell. Nowadays, people spend an average of 22 hours a day in buildings that are closed to the outside world. Here, a microclimate of their own is created by ventilation and air-conditioning systems. The task of an air conditioning system is to optimise the quality of the air and to adapt factors such as temperature, humidity and air pollution (e.g. pollen, dust and other particles) to the desired conditions.

 

To ensure that you really benefit from your air conditioning system, the VDI6022 starts at precisely these points in order to meet the standards for the proper operation of an air conditioning systems.  Here, the VDI6022 covers more than just the hygienic standard, it covers the overall condition of the system with regard to your health. The quality of the air is checked and optimised by the system.

We at profluid check at your site whether your system is causing problems due to construction, weather and maintenance-related defects and offer assistance with all questions. In addition, we provide our comprehensive test report, which you can access online via our HixDB.

After a RaumLuftTechnische Anlage has been newly built, structurally modified or not yet inspected due to the protection of existing buildings, the so-called initial inspection is the basis for the hygienic operation of a plant. During an initial inspection in accordance with VDI6022, the system concept, the design and the actual construction of the system are checked and a comprehensive inspection protocol is used to check for possible design and construction errors.  Minimum inspection locations for hygiene controls are defined and laid down in the operating manual of the plant for later repeat inspections.

A repeat inspection is the periodically recurring inspection of the hygiene of an air conditioning system.  Systems without humidifiers are inspected every three years, HVAC systems with humidifiers or buried components every two years, so that the hygiene regulations can be confirmed accordingly. The operator of an air handling system is responsible for inspection and maintenance.

Split and air conditioning units are also subject to VDI6022 and must meet the hygiene requirements of this guideline. The units are subjected to an inspection of the primary and secondary air, surface germ contamination, as well as a design test. A test report is prepared and the operating manual of the system is checked accordingly.

The assessment of the hygienic condition of an HVAC system and the risk potential to be derived from it must be determined with the aid of a professionally conducted risk assessment, based on a hygiene inspection and the documentation/operating instructions of the manufacturer/installer. 

Important state variables are for this:

  • optical inspection of the entire plant

  • Surface sampling e.g. ventilation outlets, supply lines

  • Water analyses (for systems with humidification devices)

  • Supply air measurements

In older existing plants there are still isolated mineral fibre mats as sound insulation material. In such cases, it should be clarified quickly whether these are a) asbestos fibres, b) KMF fibres according to WHO or c) modern mineral fibres.  In all cases the insulation mats must be removed. Open mineral fibre mats can release harmful fibres into the air we breathe. Which fibres are present in each case can only be clarified by a qualified laboratory. Particularly in cases a) and b) special precautions must be taken during removal and the ventilation systems including ventilation ducts must be thoroughly cleaned.

If conspicuous contamination of the room air with germs is found, the source must be identified and eliminated. The differentiation of the germs allows the source to be narrowed down in the system and at the same time provides indications of the risk potential, which ranges from slight sensitivities, asthmatic diseases, disorders of the immune system to severe fungal infections of the respiratory organs. In most cases, fungi are the triggers for disease, while diseases caused by bacteria occur very rarely in comparison.

  Interesting facts about air conditioning systems

Design and construction of a hygienically optimal RLT system

In order for an air conditioning system to work in a technically perfect and hygienically clean manner, it must be ensured that the ingress of water, dirt, leaves and other particles is effectively prevented by structural conditions. All air-bearing surfaces must be designed in such a way that they effectively prevent deposits, the release of substances hazardous to health and the formation of micro-organisms and also prevent the formation of dirt (oxidation, rust).
The air should be conducted with as little turbulence as possible and corners and edges should be avoided as far as possible.

To ensure the desired indoor air quality and to save unnecessary costs, the filters should be selected accordingly. At first glance, incorrect dimensioning may save costs, but in the further course of time it can lead to additional costs and a large number of problems. With recirculated air, the air must be cleaned accordingly by exhaust air purification methods such as air washers, electrostatic filters.

The multitude of these design aspects as well as regular inspection and maintenance lead to considerable savings potential through Longer system life Correct dimensioning and reduced maintenance effort. The correct regulation and maintenance of the system and in relation to the task of the rooms to be supplied are further possibilities to save costs and, or which can lead to an improved indoor climate.

To put it in a nutshell

The profluid - hygiene inspection is a clean thing

                              In order for you to benefit from your ventilation system, proper maintenance and control is an investment that pays off. To ensure that the operators of an air handling system meet all legal requirements and fulfil their duty of documentation, it makes sense to look for a competent partner for hygiene inspections. Thanks to our database system HiXDB ®, our inspection reports are systematically structured, clear and considerably more detailed than required by VDI6022. Thus, we guarantee a legally compliant documentation and a detailed list of defects with recommendations for action for a smooth and economic plant operation.
