Abstract: A supply air terminal device (10) has a supply air chamber (12), into which fresh air is conducted from out of doors and further from it through a nozzle gap or nozzles (12a1, 12a2 . . . ) into a mixing chamber (14). The fresh supply air (L1) induces a circulated airflow (L2) from a room (H) to flow through a heat exchanger (13) into the mixing chamber (14).

Abstract: The present invention concerns an air exhausting device, intended primarily for catering industry kitchens or equivalent. The air exhausting device comprises an outer housing, an exhaust chamber with at least one air aperture or grease filter unit, a collecting chamber for gaseous impurities and a blow chamber. The blow apertures of the blow chamber of the air exhausting device are disposed to produce a blow jet which induces a secondary air jet, which has on all sides of the blow apertures been arranged to act on its entirety in the proximity effect area. Above the blow apertures of the blow chamber has been disposed a guide baffle, arranged to direct the blow jet towards the grease filters to that the maximally efficient starting impulse of the blow jet is achieved, this impulse being arranged to substantially die out before arriving at the grease filter.

Abstract: The present invention concerns a flow regulator for gaseous substances, particularly a flow regulator intended for air in air-conditioning and ventilation installations, for maintaining the volumetric flow of the gaseous substance at desired magnitude with sufficient accuracy when the differential pressure acting across the flow regulator varies within given limits. The flow regulator comprises an envelope and a regulating member turnably disposed in the flow passage confined by the envelope (11). The torque produced by the flow of gaseous substance on the regulating member and on the other hand a counter-torque dependent on the position of the regulating member cause the regulating member turning in the flow passage to assume a position of equilibrium such that the requisite pressure drop is obtained for maintaining the volumetric flow rate at predetermined magnitude.
