Abstract: A chilled beam has separate primary and secondary inlets and plenums each or which generates separate sets of induction jets to draw air through a chilled beam heat exchanger. Various system and method embodiments are described as well as features usable in conventional active chilled beams to facilitate the use variable thermal and ventilation load applications.

Abstract: A method and a supply and exhaust air terminal device arranged in a chilled beam system. The terminal comprises a supply air chamber into which supply air is led through at least one supply air opening from a supply air duct, wherein the supply air chamber is arranged in the first end of the chilled beam; and an exhaust air chamber through which exhaust air is led from a room space into an exhaust air duct through at least one exhaust air opening, wherein the exhaust air chamber is arranged in the second end of the chilled beam and separated from the supply air chamber. The air terminal device further comprises an adjusting device configured to adjust the at least one supply air opening and the at least one exhaust air opening; and an actuator for displacing the adjusting device, wherein displacing the adjusting device causes the air flow to be obstructed through the at least one supply air opening and through the at least one exhaust air opening.

Abstract: A supply air unit including a supply air chamber, at least one mixing chamber nozzles or a nozzle gap through which a fresh airflow is conducted from the supply air chamber into the mixing chamber, a suction chamber into which a circulated airflow is sucked from an air-conditioned room space, and at least one outlet opening. At least one airflow controller through which an additional airflow is conducted from the supply air chamber into the suction chamber.

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). The combined airflow (L1+L2) combined in the device solution of the fresh supply air (L1) and the room air (L2) flow is made to flow from the mixing chamber (14) into a room space (H) or other such. The mixing chamber (14) of the supply air terminal device (10) has in the mixing chamber (14) or in connection with this in a flow passage (14?) a film element (15), preferably a film-like electric resistance.

Abstract: The invention concerns a supply air terminal device (10) and a method for regulating the airflow rate. The supply air terminal device (10) comprises a heat exchanger (11), with which a circulated airflow (L2) conducted from a room can be either cooled or heated. The supply air terminal device (10) comprises a mixing chamber (12), into which mixing chamber (12) the air chamber's (15) nozzles (16a1, 16a2 . . . 16an) or a flow gap (16) open to conduct a primary airflow (L1) into the mixing chamber (12), whereby the primary airflow (L1) from the nozzles (16a1, 16a2 . . . 16an) or through the flow gap (16) as a flow (Qs) will induce a circulated airflow (L2) from the room (H) to flow through the heat exchanger (11) into the mixing chamber (12). The combined airflow (L1+L2) is conducted into the room (H). The supply air terminal device (10) comprises a regulator (100) bypassing the nozzles (16a1, 16a2 . . .
