- Oliver: If it gets really hot and the temperatures reach 30 degrees and more, many owners ask themselves same question. Should I my ventilation system now so that it not additional warm air into house? The short answer is no, you should not do A modern living room ventilation ensures that fresh air into house and used air is out. So it primarily responsible for the air quality and not for the heat in house. The heat does not through the ventilation system into the building, but through windows and direct sunlight. That is shading, roll-in or sun protection systems are significantly more than the question of ventilation Nevertheless, are some settings with which you best out of the system. So if the ventilation system has a so-called summer pass, it be activated. This ensures that the cool night air is unnecessarily over the heat exchanger, but directly into the building. This way the system can help to the rooms down again That's why it's worth to the ventilation system run little stronger at systems even a special ventilation mode. During day, the air volume can be reduced, especially if no one is at home. Now to the actual question, can a ventilation system actually cool? Yes, could say a little bit. The ventilation system does not a climate system. who expects that living room will from 28 to 21 degrees, will be disappointed. But what the system can is the outdoor air. Modern systems use the heat exchanger for and can down in a few degrees. even more effective with a heat exchanger that uses corresponding cooling temperatures in earth. This is called passive cooling. Depending on the building and system, a few degrees of temperature gain occur. Often this is sufficient to the space climate much more pleasant. order this to work, of course, all residents must play The most important rule is to windows closed and sun rays. Whoever 32 degrees outside temperature, works against any ventilation system in world. It is to morning and at night, the shading closed, and the ventilation system specifically for night cooling. So would say that summer the living room ventilation can a noticeable contribution to more comfortable room climate, the air quality high and the night cooling optimally. That is why should it on hot days.
