BUILDING WITH DEMAND-CONTROLLED HEAT EXCHANGE SYSTEM FOR VENTILATION AND HEAT EXCHANGE SYSTEM

摘要

A building comprises several rooms (1, 2), of which one room is connected to a secondary air supply duct (3, 4) and a secondary air discharge duct (5, 6), and of which another room is connected to another secondary air supply duct and another secondary air discharge duct. There is also a heat exchange system (9) which is connected to the secondary air supply ducts (3, 4) and the secondary air discharge ducts (5, 6) and to a main air supply duct (7) and a main air discharge duct (8), which heat exchange system (9) comprises a housing (12) which contains a supply flow passage (15) and a discharge flow passage (16). The housing (12) is provided with at least one flow regulator (17) which is located between the heat exchanger (12) and a secondary air supply duct (3, 4) and/or at least one flow regulator (17) which is located between the heat exchanger (12) and a secondary air discharge duct (5, 6).
