Abstract: A diffuser cartridge (10) of restricted height is provided for controlling flow of air in an air conditioning system. The cartridge (10) has two axially aligned temperature sensitive elements (34,68) for respectively sensing room temperature and duct temperature variations. Arms (12) are provided for displacing an air flow baffle (B) and a control structure is provided for displacing the arms (12) in response to sensed room and duct temperatures. The control structure pivots the arms (12) cam-fashion as it is moved vertically by the temperature sensitive elements (34, 68). The control structure has two springs (54,56) that act in series to counter movement of the control structure by the temperature sensitive elements (34,68). The springs (54,56) are nested coaxially within each other, with an intermediate component (48) transferring compressive loads from one spring to the other.

Abstract: A self-modulating diffuser for regulating the volume flow of conditioned air from a duct to a selected space, affording a high level of air mixing and sound performance combined with ready control of the space temperature comprises an adjustable square cone plaque-type ceiling diffuser with an outer cone for developing horizontal air flow, a square plaque for attachment to the outer cone and an inner dampening cone positioned intermediate the outer cone and square plaque. Separate first and second sensor means measure the temperature in the duct and in the room space, respectively, and direct digital control means respond to signals from the sensors to produce a control signal which operates an actuator mechanism for adjusting the position of the inner dampening cone.

Abstract: An air circulation and mixing device is disclosed which can cover a ceiling air ventilation duct, taking air discharged from the duct and drawing air at the room's ceiling, mixing the two, and redirecting the mixed air so that it is discharged radially and parallel to the ceiling, rather than directly downwardly. The device has an open frame whose sides may be covered with removable air filtration media and which forms a primary interior having a lower aperture and normally an upper aperture. An open-sided grille below the lower aperture forms a secondary space. A fan is mounted within the primary space and turns blades within the lower aperture and a disk at the bottom of the secondary space. An annular plate surrounding the fan housing blocks downward flow of incoming air and forces the air to flow radially outwardly around the edge of the plate, thus also insuring good mixing with the incoming ceiling air.

Abstract: A ceiling ventilation inlet includes a housing having an air inlet aperture, an air outlet aperture, and a baffle supported for linear movement adjacent the air outlet aperture. A spring is positioned such that the baffle moves dependant upon air pressure difference between the confinement space and the external environment. Air entering the housing opens the baffle and enters the livestock confinement building in a 360 degree dispersion pattern. The spring causes the baffle to direct the flow of air into the confinement space at a near constant rate so as to optimize ventilation. The greater the air pressure difference between the confinement space and the external environment the greater the air outlet area becomes. Since the inlet is responsive to the pressure difference and the air outlet area increases or decreases in size, the airflow velocity entering the confinement space may be optimized at a near constant rate.

Abstract: An air diffuser apparatus has a box-like air diffuser chamber with sheet metal side walls, that are provided with a series of laterally spaced outlet orifices. Each orifice is formed by cutting out wing portions of the sheet metal on each side of a center line of the orifice and bending the wing portions outwardly to a position inclining toward this center line. The wing portions define an air flow passage tapering in an outward direction. The chamber has a base connected to a lower edge of the side walls that includes a layer of heat insulation material. An upper structure closes the upper end of the chamber and has an inlet opening for introducing pressurized low temperature air into the chamber. This arrangement is highly efficient for diffusion of low temperature air and can be of essentially all-metal construction.

The baffle plate (9) is attached to the exhaust connection piece (3) by means of a spring element (7), preferably by means of hook-shaped end (10) of the spring which fits into recess (6) of a flow-dividing bulkhead (5) of the exhaust connection piece (3). Another part of spring element (7) is made as a compression spring which has compressible outer part (11) which rests against a shoulder (12) of the exhaust connection piece (3). The invention enables simple, cost-favorable attachment of a baffle plate on an exhaust connection piece by means of which outstanding noise damping is achieved.

Abstract: An air diffuser for diffusing conditioned air into a room has a diffuser body mounted in a housing to define an air channel which narrows towards the outlet end of the housing to produce a venturi-like effect causing the air to speed up as it leaves the diffuser so that the conditioned air can penetrate stratified layers of air in the room. The diffuser body is of tapered form having a narrow upper end portion and a wider lower end portion disposed in the open, outlet end of the housing. The diffuser body has a surface which faces the internal surface of a sloping side wall of the housing and which is inclined at an angle to the vertical greater than that of the sloping side wall of the housing to provide the narrowing air channel. The diffuser body is adjustably mounted for movement relative to the housing so that the flow of conditioned air leaving the outlet end of the housing can be adjusted.

Abstract: A thermally controlled diffuser comprises a means for connecting the diffuser to a duct, a divergent outlet, a means for deflecting flow from the divergent outlet, and a means for supporting the flow deflection means in a predetermined positional relationship with respect to the divergent outlet. The support means includes a temperature sensitive mechanism whereby the predetermined positional relationship between the outlet and the flow detection means may be varied depending on a temperature sensed by the temperature sensitive mechanism so as to produce a variation in the outlet flow pattern of the diffuser. The thermally controlled diffuser may preferably be a ceiling diffuser, and preferably the variation in the positional relationship is in a vertical direction when the diffuser is installed. A method of automatically varying the flow pattern of a diffuser is also described.

Abstract: An air vent for the generation of high turbulence air jets is comprised of a rotationally symmetrical casing having a flared discharge mouth. A deflector plate is mounted in the plane of the mouth to define with the mouth an annular discharge opening. An air guide is mounted within the casing that includes an annular flared deflector portion located adjacent the discharge mouth of the casing. Radially extending twist paddles or fins are mounted on the air guide to impart a twist to the air stream. The air guide is preferably adjustably mounted within the casing for movement axially thereof whereby when the deflector portion of the guide is disposed above the plane of the mouth portion a spreading of the air stream is achieved, and when the deflector is located below the plane of the mouth portion a concentration of the stream is achieved, intermediate effects being achieved at intermediate positions of the guide relative to the casing.
