This invention relates to an air heating and ventilation system, comprising a supply air duct (1); an exhaust air duct (2); a heat recovery unit (LTO) between the supply and exhaust air ducts (1, 2) for transferring heat from the exhaust air into the supply air; a heat storing unit (MV) for storing heat and for delivering it into the air passed therethrough; and a damper (SP) in the supply air duct (1) for passing air partly directly and partly through the heat storing unit (MV) into room spaces (3, 4, 5, 6) to be heated. In the invention, in order to enable efficient adjustment of temperature separately in each room space within the air heating system having the heat storing unit (MV) as the main source of heat, the damper (SP) is controlled in such a manner that the heat storing unit (MV) supplies the heating system with basic heat while adjustment heat is supplied separately for each room space by duct heating units (KL4, KL5, KL6) provided in a supply air distribution duct (7) and controlled by thermostats (TE4, TE5, TE6) for each room space, respectively. |
