Definitions
- the present invention relates to a device for supply air with at least two different air outlets for air of different temperatures and with one device, which distributes the air to the air outlets.
- Air supply systems according to the above type are known as such for temperature control supply air to a room from the ceiling, for example.
- electrical or pneumatic auxiliary energy and the corresponding Switching signals come from control devices that operate according to specified algorithms work.
- the distribution device which the air is distributed to the air outlets is equipped with a device that the Air distribution automatically and directly in response to the air temperature, d. H. in particular without a control device and electrically or pneumatically operated Actuation mechanisms must be provided.
- the air distribution adjuster itself is temperature dependent or working in response to temperature or changes in temperature Actuator. It is now possible to use the present invention to make expensive and error-prone Actuating components, for example electrical or pneumatic actuating elements for flaps, and the overall system becomes cheaper and less prone to errors. In addition, no separate drive energy needs to be applied, since the supply air temperature even the drive energy delivers.
- the adjusting device has d. H. the device that responds to the air distribution independently and directly to the air temperature, a temperature variable, especially one with temperature element variable in length or size or position, which is mechanical acts on the distribution device. It is possible to use the setting device as To form pistons that are engaged with the distribution device so that it does their distribution activity about its stretched state.
- the mentioned distribution device can be a throttle device in front of one of the air outlets his.
- this throttle device can be a Segment disc with two mutually rotatable segments, so be one centrally positioned segment disc, in which, when closed, all segments the air flow completely interrupt and an opening condition is achieved by a Segment is rotated so that it overlaps the other and thereby clears the air passage.
- the temperature-variable element in particular the expansion piston, engages in one embodiment of the present invention on the throttle device, in particular in one Segment of the segment disk. In a preferred embodiment, this counteracts a force the restoring force exerted by an elastic element, in particular against the restoring force a spring closing the throttle device.
- the device according to the invention preferably has a warm air outlet and cold air outlet on, the distribution device, in particular the throttle device, being preferred the segment disk is arranged only in one of the outlets, preferably in Hot air outlet.
- the distribution device in particular the throttle device, being preferred the segment disk is arranged only in one of the outlets, preferably in Hot air outlet.
- the air outlets can be arranged concentrically, preferably so that the cold air outlet is arranged on the outside in a ring around a central warm air outlet.
- the device it is also possible to design the device so that one of the air outlets, in particular the cold air outlet, the air in the horizontal direction, preferably as a swirl outlet lets out while another air outlet, especially the warm air outlet allows the air to flow out in a vertical direction.
- This configuration makes it possible, in particular when installing the device on the ceiling of a room, avoid a cold drafts occur when the room is to be cooled.
- a highly inductive and a warm air outlet a low-induction air supply.
- the device according to the invention shown in Figures 1 to 3 has a supply air distribution box 1, which is shown in Figure 2 in a longitudinal sectional view.
- Figure 1 shows accordingly a view from below of the distribution box 1 and in Figure 3 is one Top view shown, with the lid omitted to make the components visible.
- the distribution box 1 which is supplied with supply air from the right side in FIG. 2, is on attached to the ceiling of a room to be heated or cooled. It is a component of the Air and air conditioning technology for the distribution of mechanically conditioned supply air.
- the distribution box 1 forms a housing, the functional parts of which are on the lower cover side are located. These functional parts are a ring-shaped external cold air outlet 2 and a concentric warm air outlet 3.
- the cold air outlet 2 is a swirl outlet trained and blows the cold air horizontally so that it is distributed near the ceiling and can sink down. It consists of a large number of slot-like blow-off openings.
- the preferred embodiment described here has only a single throttle element, and this throttle element is a segment disk 5 which is in the warm air outlet 3 is arranged.
- the segment disk 5 has two segments which can be rotated relative to one another in the central warm air outlet 3, which overlap their individual elements release the warm air outlet 3, but can be turned towards each other in such a way that the warm air outlet 3 is blocked for an air flow.
- the warm air outlet 3 closes automatically and the air flows horizontally into the room through the cold air outlet 2.
- the supply air volume flow components shift between the swirl outlet 2 and the warm air outlet 3 only by means of adjustable pressure loss displacement, which is determined by the rotational position of the segment disc 5.
- the control of the opening or closing state of the segment disk 5 no longer be carried out by electrically or pneumatically actuated actuators, but it is done by a single actuator, the actuating effect directly from the temperature is dependent on the inflowing air.
- Such an actuator is shown in FIG. 4, and as an expansion piston 7, which at an engagement point 10 on the rotatable segment of the segment disc 5 attacks.
- the expansion piston 7 can with increasing supply air temperature without further Auxiliary energy turn the rotatable segment of the segment disc 5, so open it while it when the supply air temperature drops, the spring 6 counteracts the rotatable segment of the Segment disk pushed back into the closed position by an attack at the point of engagement 9.
- the expansion piston 7 has, for example, an expansion material filling and the working temperature range the piston 7 can be almost arbitrary by the choice of the expansion material be determined. It is preferably between 20 ° C and 30 ° C for the supply air temperature and the characteristic is linear (temperature / actuating force).
