Abstract: A system and method provides for controlling condensation generation in an air conditioning system for use in a bed (mattress). During active operation of the air conditioning system to generate conditioned air, the relative humidity of ambient air is measured and operation of one or more thermoelectric devices (TEDs) within the air conditioning system in response to the measured relative humidity is adjusted to control condensate buildup. During a subsequent drying operation, the relative humidity of the ambient air is measured and the drying operation is adjusted or otherwise controlled based on the measurement.

Abstract: A security housing contains a housing body having ventilation openings for supplying air to a heat source, in which air convection takes place for dissipating heat. First air guide elements are disposed in the housing body on a first side of each of the ventilation openings and are shaped for partly covering the ventilation openings. The first air guide elements each have a base integrally molded on the housing body, the bases are spaced apart from each other such that, in each case one of the ventilation openings is further defined. A removable security housing part is disposed inside the housing body and forms an air guide duct. Second air guide elements are disposed in the air guide duct and are shaped such that they cover the ventilation openings and the first guide elements such that, non-rectilinear air guidance is ensured.

Abstract: A displacement ventilation, low noise level, mixed air, HVAC system for ventilating a commercial or educational facility. The system includes a central HVAC air handling unit containing first and second duct works for receiving and transmitting conditioned air to rooms of the facility. Additionally, the system includes at least one air displacement terminal housing for delivering conditioned air to the room, where the air is delivered through an outlet in proximity to the floor of the room in a displacement manner.

Abstract: An air handling system for an enclosed space in a building includes two induction units that can be mounted above a ceiling. Each unit has an elongate air plenum section and an air mixing section forming an air mixing chamber. Air nozzles extend into the air mixing chamber and are mounted on a side of the air plenum section. Each nozzle has an inlet end opening into an interior chamber of the plenum section. Each air mixing section has an air outlet formed at a lower end thereof and a side air inlet for permitting return air to flow into the mixing chamber. Each induction unit is mounted so that the air mixing section extends at a substantial acute angle to the ceiling with the air outlet positioned where the mixing section meets the ceiling. The return air is drawn by a venturi effect created by the nozzles into each mixing chamber.

Abstract: The air mixer defined herein serves for static mixing of a heated air stream in a flow channel of a circulated air stream upstream of a heat treatment chamber for drying textile goods or tissue webs for example. For this purpose the air mixer is provided with air mixing parts that consist of hollow bodies arranged in the flow cross section of the first air stream with spaces between them, said bodies being provided to receive and conduct the second air stream with inlet openings and outlet nozzles located endwise on one side.

Abstract: A ventilation unit for use with a heating or cooling system that is decentralized and does not require large conduits is disclosed. The system includes at least one fresh air intake; a fan operatively connected to the at least one fresh air intake for drawing air from outside of a space into the fresh air intake; and at least one ventilation unit located in the room. The ventilation unit includes a conduit defining an air passage having a first and second opposite ends, a diffuser operatively connected to the fresh air intake for outputting fresh air near the second opposite end of the conduit and for drawing ambient air from the room through the first opposite end. The ventilation unit also includes a heating element located downstream from the first opposite end inside the conduit.

Abstract: This invention relates to an induction air handling unit of the type that uses a primary air flow to induce flow of secondary air through the air handling unit. It comprises an induction chamber (2) having an air flow entrance (22) and an air flow exit (23) and a nozzle (10) having an outlet (12) located within the induction chamber (20). The nozzle (10) is connected to a primary air flow that causes a secondary air flow to be induced through the induction chamber (20) via the entrance (22) and the exit (23). The nozzle (10) is characterized by the edge (12) forming an outlet that is of a scalloped shape. This has a dramatic effect on producing noise output from the nozzle (10).

Abstract: A fresh air inductor device for installation with a forced-air heating appliance ensures an adequate supply of fresh air is tempered prior to introduction to the heating appliance. Air from the supply plenum of the heating appliance is applied to the device together with outside air. The supply plenum air enters the device through a venturi tube, the decreased pressure created draws in outside air, which mixes with the supply plenum air before being introduced to the return plenum of the heating appliance. Various configuration of venturi tube within the air inductor device regulate flow rate and air mixing characteristics.

Abstract: Mixing section for outdoor air and return air in an air-conditioning apparatus, the mixing section being positioned between a supply duct supplying outdoor air into a room and a return duct removing exhaust air from the room for mixing outdoor air and return air. The supply and return ducts comprise adjusting devices for adjusting the air flows. To control the air flows at different mixing ratios and to make the mixing more efficient, guides are provided after the adjusting devices of both the supply device and the return device in a mixing space so as to divide the air flows passing through the adjusting devices into a plurality of separate interlapping air jets crossing each other.

Abstract: A device for regulating the temperature in a room having an extraction vent and a delivery vent, using pulsed low-velocity air flow (qs). A pipe is provided in communication with a pressurized air supply duct via extraction and delivery orifices, and the extraction vent and the delivery vent open out into the pipe. Two coaxial air streams are formed in the pipe between the extraction and delivery orifices, and a central stream is produced in which the air moves at a high velocity and a peripheral annular air stream is formed surrounding the central air stream in which the air moves at low velocity.

Abstract: An apparatus for attaining improved flow uniformity through and at the exit of an air duct by mixing and distributing the air flow. The apparatus has a wall containing a plurality of convoluted corrugations or lobes arranged in conjunction with an airfoil shaped faired body to form an ejector passage between the wall and the faired body. There is a primary flow passage on the side of the wall opposite the ejector passage. The corrugations extend into both the primary flow and ejector flow passages so that a lobe in one passage is a trough in the other passage. Air flow in the primary flow passage acts to cause a flow through the ejector passage and thus a suction in the inlet to the ejector passage. The suction acts upon streamlines around the apparatus to obtain improved downstream air flow performance. One embodiment of the flow distributor increases the spreading half angle at the exit of an air flow duct.
