Definitions
- the invention relates to a mixing device for air conditioning Plants for mixing cold air and warm air, with a cold air supply and a warm air supply, with a mixing area and with a mixed air outlet, the cold air supply and the mixed air outlet at least are roughly in line and the supplied Warm air flow at approximately a right angle in the between the cold air supply and the mixed air outlet provided mixing area opens.
- Such mixing devices are used, for example, in air conditioning technology Systems used and used on ships for mixing cold air and warm air.
- a known Mixing device opens the warm air supply approximately in at a right angle into a flow channel Cold air supply, so that due to the essentially the cold air meet vertically and mix the warm air.
- the disadvantage here is the elaborate channel and thus the overall construction of the mixing device, since at parallel guidance of the in the cold air supply and in the warm air supply opening flow channels in front of the Warm air supply an elbow for deflecting the warm air must be provided.
- the object of the invention is to overcome the aforementioned disadvantages to avoid and specify a mixing device that a has a more compact design.
- the mixing area is designed as a mixing chamber, the warm air supply in arranged parallel to the cold air supply is and a deflection device for the guide the warm air flow to the mixing area is provided. This allows the hot air supply and Cold air supply connected flow channels in the immediate Spaced from each other and parallel in the mixing device open, so that the overall height is reduced can be.
- a wall in particular one, can be used as the deflection device made of a sound-absorbing material, such as. B. mineral wool, existing wall can be provided. But it is also quite conceivable that the wall made of sheet metal or is made of another suitable material.
- the orientation of the wall is square Mixing device essentially perpendicular to the direction of flow the fed into the mixing device Warm and cold air.
- the wall can advantageously be between two extend opposite housing walls of the mixing device and a recess, especially one in the Alignment of the cold air supply lying recess.
- the cold air volume flow supplied is greater than the warm air volume flow supplied with an aligned arrangement of the cold air supply with major pressure losses avoided in the recess.
- the cold air supply can be used to regulate the volume flows and / or a flap in the warm air supply be provided.
- These flaps can, for example, by an actuator can be adjusted in its orientation. It can also be self-acting flaps, against a restoring force by the volume flow pivoted from their open position into the closed position become.
- the deflection device and / or the flap (s) can integrated into the mixing device designed as a mixing chamber his. Such an arrangement is characterized by a particularly compact design.
- the mixing device consists of a housing 1, the through a made of a sound absorbing material, such as z. B. mineral wool, existing wall 2 in two subchambers 3, 4 is divided.
- a sound absorbing material such as z. B. mineral wool
- the left compartment 3 the represents the actual mixing area and essentially serves as a mixing chamber, open a cold air supply 5 and a warm air supply 6, which in turn over Flow channels, not shown, to an air conditioning system Are connected.
- a flap 7, 8 are provided to the volume flow in the cold air supply 5 or the warm air supply 6 regulate.
- the warm air supply 6 and the cold air supply 5 protrude into the left compartment 3.
- the improved acoustic properties of the mixing device there may be flap noises from the wall 2 can be included.
- the wall extends 2 substantially perpendicular to the direction of flow (Arrow 10) in the warm air supply 6.
- Arrow 10 the warm air in Direction of arrow 10 'deflected substantially at right angles and occurs at a right angle towards the Arrow 9 flowing cold air. This will make a high one Degree of mixing achieved.
- a recess 11 is provided through which the mixed air, d. H. the mixture of the cold air and the warm air, in the direction of arrow 12 into the right sub-chamber 4 flows.
- a centrally located mixed air outlet 13 provided that with the remaining part of the air conditioning Plant is connected. The mixed air enters Direction of arrow 14 from the mixing device into one subsequent flow channel, not shown out.
