Definitions
- the invention is based on the object of a method to create a temperature control of a hall with tolerable Device and energy expenditure enables.
- the object is achieved according to the invention by a method for tempering a hall, especially a warehouse, in the case of a drive nozzle arrangement connected to a blower a driving jet with high flow velocity is generated by a with an outlet nozzle assembly provided suction chamber is guided, with the Suction chamber conditioned air is sucked in together blown into the hall with the driving jet as tempering air becomes.
- a correspondingly high delivery rate of Blower succeeds a multiple of that conveyed by the blower Suck air in conditioned air through the suction chamber and with the air of the jet as tempering air to blow into the hall.
- the flow velocities also depend on the respective Tempering task. Should be at high outside temperatures the hall must be tempered in the sense of cooling, must be in the Area of the hall end the flow velocity of the air in the floor area you can still feel the cold Air in the front hall areas like an inversion sinks. If the hall is to be used at low outside temperatures The heated temperature control air must be tempered for heating purposes blown in with a slightly higher air flow to a certain extent to a circulation of the temperature control air in the hall. Especially It is useful in both cases if the temperature control air in the ceiling area of the hall, preferably along the hall ceiling is blown in.
- the air flow in the hall can now vary depending on the task are also influenced by the fact that at least a subset of air as conditioned air from the Hall returned to the suction chamber, so at least partially is circulated. This is then, for example important if the hall is heated in terms of heating shall be.
- At least a partial air quantity as conditioned air through conditioned air of the suction chamber is fed. This is important, for example, if the hall is to be tempered in the sense of cooling, so that at night with an outside temperature that is lower is as the air temperature in the hall, practically without Cooling unit can be worked.
- the air for the propellant jet from the Hall is suctioned off. While it is at a tempering in Cooling is expedient that the air for the Driving jet also sucked out of the conditioned air it is with temperature control in the sense of heating, d. H. at lower outside temperatures, the air for the Extract the driving jet from the hall in order to maintain the heat content the air in the propellant jet, which if necessary then additionally is heated to be able to take advantage of.
- the method provides that at high daily outside temperatures during the night time to generate the propulsion jet and / or conditioned air becomes. Because such warehouses are usually insulated today are executed and also the gates for loading vehicles are equipped with locks to allow an air exchange here and thus a temperature exchange between the conditioned It is to avoid air and indoor air as much as possible possible to effectively cool a warehouse without cooling units to temper.
- the cool conditioned air is during the night time, for example from 0 a.m. to 5 a.m. from sucked in outside.
- the connection to the conditioned Air shut off both on the suction chamber and on the blower and circulating the hall air.
- it is useful if at least part of the indoor air is discharged to the outside. This is particularly useful at the time when the lowest outside temperatures exist are so that warm air present in the hall to the outside is pressed.
- cooling temperature during the day conditioned air is circulated over the hall, it can also be useful at very high outside temperatures be when at least the air is cooled for the propellant jet becomes.
- the suction chamber is supplied under pressure at least temporarily and / or at least some of the conditioned air.
- the tractive force of the propellant jet is sufficient to ensure sufficient air circulation, the outside air, which is led through the suction chamber as conditioned air, is already under pressure at a clear flow velocity that extends over the entire cross section to the propellant nozzle arrangement brought up, so that due to the lower energy losses in the further acceleration of the total air volume by the propellant jet a higher exit speed is achieved at the outlet nozzle arrangement and so the high air flow important for the air exchange and cooling of the hall is improved during the aftertime. It may be advisable to supply the conditioned air under pressure only during an initial phase in order to achieve high heat dissipation in the shortest possible time and then to suck in conditioned air in “normal operation”, ie only under the influence of the propellant jet.
- the required pressure increase of the conditioned air can be brought about by an additional fan in the suction area of the suction chamber or in the form of a partial flow branched off from the main fan that generates the propellant jet by means of a bypass.
- the conditioned air is below Pressure in the direction of the jet through the suction chamber is, expediently the pressure increase for the conditioned air seen in the flow direction before entering of the driving jet.
- the invention further relates to a device for temperature control a hall, in particular a warehouse, according to the invention Method.
- This has a blower that pressure side via a pressure channel with a driving nozzle arrangement is connected, which opens into a suction chamber, wherein the suction chamber in axial assignment and at a distance from Propellant nozzle arrangement has an outlet nozzle arrangement and with at least one openable and closable inlet opening for conditioned air and at least one opening and closable inlet opening for indoor air is provided.

- the propellant nozzle arrangement has a large number side by side arranged individual nozzles, which with the pressure side of the blower duct connected to the blower. In order to it is possible to get the required propulsion jet through a A large number of individual beams arranged next to one another at a distance to form each one a high flow rate exhibit.
- the outlet nozzle With a driving nozzle arrangement in the form of a Rectangle with, for example, in two rows one above the other and to several individual nozzles arranged side by side then the outlet nozzle has a corresponding rectangular contour, but with a correspondingly larger cross section.
- the free flow cross section the outlet nozzle arrangement is here on the Exit velocity of the propulsion jet and the delivery rate and flow velocity of the exiting into the hall To adjust the beam to the temperature control air.
- the Outlet nozzle arrangement means for jet alignment and / or Has beam shaping can for example by on or in the free flow cross section the pivotable arranged in the outlet nozzle opening Slats are formed over the direction of the beam can be influenced.
- These slats can, for example be aligned horizontally to the jet of tempering air lead more or less far into the hall.
- the slats can also be aligned vertically be, where appropriate partially pivotable in opposite directions can be designed so that, for example Center of the air jet emerging from the outlet nozzle in a straight line Direction continues while side areas of the Air jet can be deflected to either side to be able to pull the entire air jet apart like a fan. It is also possible to be horizontal and vertical to combine directed slat arrangements with each other, to achieve a differentiated beam shape.
- the part of the pressure channel running in the suction chamber is provided on the outside with heat transfer surfaces. This arrangement is particularly important if heated air is blown in through the propellant jet should. This makes it possible for the pressure channel in the Conditioned air already flowing past the suction chamber Part of the desired amount of heat via the heat transfer surfaces is able to absorb, so that a uniform Temperature profile for the beam cross section exiting into the hall of the tempering air.
- the suction chamber seen in the flow direction before the mouth the driving nozzle arrangement a fan for acceleration of the conditioned air flow.
