A two-zone mixing model describes the concept(s) of and defines the effectiveness of ventilation. Multiroom aspects and procedures for measuring ventilation effectiveness are dealt with. The simple two-zone model, experimentally verified by laboratory tests, predicts generally high effectiveness for ventilating systems using the displacement principle, taking advantage of stratification. Tests using this principle in an office room for one to three persons (28 m/sup 2/, 2.8 m ceiling height), are reviewed. Stratification was secured by supplying the ventilation air with a temperature always lower than the air temperature in the zone of occupation. Necessary heating of the room was provided for by using panel heaters under the windows; the air supply was located at the opposite wall. Seasonal variations are addressed.
