The invention relates to a supply air apparatus, which is meant for producing outdoor air into an indoor space assisted by an auxiliary powered blower arrangement (1) by simultaneously mixing the outdoor air (u) to be brought into the indoor space with air from the indoor space (s). The supply air apparatus comprises in connection with an outdoor air flow way that exists in a structure (W) in a building between the indoor space and outside air a flow space (V) along with its flow connections for outdoor and indoor air for mixing the above with each other, the blower arrangement (1), such as one or more, advantageously on axial principle operated, blowers, and a blow flow arrangement (2) for leading a mixed flow of air (us) into the indoor space in the building. The supply air apparatus comprises in connection with a supply air device (X), such as a replacement air valve or like, in an outer wall of the building a built-in air distribution device (Y), which comprises: a boxstructured frame (R); an internal flow space (V) in the frame; an inflow arrangement (SV) of outdoor and indoor air that joins with the flow space and opens into an internal space (ST) in the building; the blower arrangement (1), such as one or several parallelly coupled device blowers or like; and a blow flow arrangement (2) leading the mixed air (us) into the indoor space. |
