As passive house residential buildings and non-residential buildings are almost airtight, it´s very important to exchange the “used” indoor air by fresh outdoor air to keep the hygienic standards high. With the right technology a cheap and temperature neutral air conditioning is guaranteed.
Non-residential buildings like banks, schools, industry buildings etc. set even more requirements to the air conditioning as in those buildings the heat loads are produced by the equipment in the building like machines, computers and other working tools and don’t depend on the outdoor climate.
Technologies like free cooling are able to cool the room during the night and in the morning without additional cooling energy needs. The unit is equipped with EC-fans with an active air flow control which keeps the pressure conditions constant in all possible operational modes and conditions of the filters.
