Abstract
A method for regulation of ventilation, wherein air is removed out of a room space (H) or equivalent through an air-conditioning device (10) as outlet air (L.sub.1) and in which said air-conditioning apparatus (10) part of the outlet air is recirculated as return air (L.sub.2) back into the room space, whereby return air (L.sub.2) is mixed with outdoor air to be passed into the room space. Before the outlet air (L.sub.1) is made to flow via the return-air damper (15) to the point of mixing (C) of return air (L.sub.2) and outdoor air, the outlet air is fitted to flow first via the outlet-air damper (14) placed on the outlet-air duct (11a) and, thereupon, via the return-air damper (15). The portion (L.sub.3) of the outlet air (L.sub.1) that is not recirculated via the return-air damper (15) or equivalent is removed as waste air (L.sub.3), without throttling, out of the air-conditioning device. The invention also concerns an air-conditioning apparatus.
