Air as a giver of life. The healthy quantity of fresh air. A regulated exchange of air is the be all and end all of a healthy indoor climate. The difficulty lies solely in finding the right balance between fresh air supply and heat loss. Or put differently: the art of ventilation that is ecologically sound and saves heating costs. Unfortunately there is no pat solution for this – how long the optimal exchange of air takes depends on wind and weather, the position of the opened windows, and many other factors. TROCAL has collected for you a few simple and helpful basic rules, information,...

DThe indoor climate as a feel good factor When cooling becomes a problem High air humidity becomes a problem in particular when temperatures drop during a heating period. When the radiators are turned down, for instance when there is nobody home, the indoor temperature falls – and therefore the quantity of water vapour that the ambient air can absorb. Earlier this was not a problem. Yet nowadays, because houses are very well sealed and moreover are fitted with modern energy saving windows and thermally insulating glazing, the excess moisture can no longer escape. Although a cubic metre of...

Fresh air as a permanent guest. one hand we have countless factors that affect the relative air humidity, including the need for ventilation, on the other we have homes and buildings in diverse shapes and sizes. Basically there are two kinds of ventilation systems: free ventilation and forced ventilation. Free ventilation Free ventilation is the name given to all ventilation modes that operate without mechanical aids, e.g. windows are opened to let excess moisture escape. This utilises the pressure difference across the two sides of a building: the air flows in through open windows or...

More than air and water. Carbon dioxide The most important reference value for indoor ventilation is the carbon dioxide content. Although the CO2 content of indoor air rises when people are present, no ventilation is needed to reduce the CO2 values when the room is used normally. One of the most important factors for an effective ventilation behaviour is the position of the opened windows. When the wind flows around a building a stagnation pressure is generated on the side facing the wind and a partial vacuum on the side facing away. In addition the direction of ventilation is affected by...

TROCAL ventilation system. Air supply – systematically There are a large number of cases where the conventional ventilation methods are inadequate, e.g. when somebody is home only rarely. This also applies to weekend and holiday homes. Here the TROCAL ventilation system AirMatic provides for fresh air – also without active ventilation. The TROCAL ventilation system AirMatic is the perfect solution for obtaining a healthy indoor climate at all times, even when the windows are closed. It is also ideal as a retrofit. The TROCAL 88+, AirMatic AD, and AirMatic MD ventilation elements with...
