Ventilation and Air Conditioning technology for private and commercial use

correct ventilation in the company and at home

Air conditioning technology, how to maintain a healthy climate within your own four walls

Contribution by Knuth Ensenmeier, Chamber of Crafts Swabia

For the well-being in rooms, a relatively limited area - a comfort zone - is defined, where air temperature and relative humidity are in a balanced relationship. Not only is performance at its highest here, but the health factor is also optimal with regard to many other room parameters. From a biological point of view, the risk of infection of the respiratory organs and the general risk of allergies is also lowest at a room humidity level close to 50 percent. Add to this enough clean fresh air and a pleasant scent, and you feel good.

A healthy climate at home

Heating, cooling, humidifying and dehumidifying rooms

If you want to enjoy this kind of comfort all year round and around the clock, you will not be able to avoid technical installations in most climate zones. In addition to optimising the four thermodynamic functions: heating, cooling, humidifying and dehumidifying, sufficient air exchange and, if necessary, filtering of the outside air must be ensured. Regular shock ventilation helps, but is neither comfortable nor particularly economical. Today, ventilation systems are planned and installed in most new buildings, also for reasons of energy saving. These extract the stale air in the cooking or sanitary areas and discharge it to the outside via a heat exchanger using the counterflow principle. At the same time, cold or warm air flows into the building from outside - depending on the season - to be brought to the desired temperature. Modern heat pump technology is increasingly being used here, which can heat in winter and cool and dehumidify in summer.

Saving heating costs

For new buildings with current energy standards, such installations quickly pay for themselves in terms of the heating costs saved. In existing buildings, the costs and benefits must be calculated individually. Here, ventilation or air-conditioning systems can be retrofitted room by room if required, which can cool, heat and dehumidify. Selection, installation and maintenance should be left to a specialist in any case. The tradesmen in the region will be happy to advise you.
