Definitions
- the invention relates to an arrangement for the air conditioning of Spaces or the like according to the preamble of the claim 1.
- Such an arrangement is known for example from US-A-5558274.
- a non-differentiable over the space surface air flow over a ceiling, preferably filter cover, blown into a room after the air flow was cooled or heated accordingly via an air conditioner In known arrangements for air conditioning of rooms or the like, a non-differentiable over the space surface air flow over a ceiling, preferably filter cover, blown into a room after the air flow was cooled or heated accordingly via an air conditioner.
- an air conditioner which are used in particular for the air conditioning of clean rooms, thus a single unit for air conditioning of the air is used, which also includes a blower, so that a circulation of the air flow is made by the air conditioner on a filter blanket through the room and the air conditioner.
- the disadvantage of such an arrangement is the comparatively high pressure loss as a result of high resistances, for example by a plurality of throttle valves, which are arranged in the filter cover and should generate a uniform air flow over the space area.
- Another disadvantage of this known arrangement is that the filter cover with one and the same air flow, ie with air at the same temperature is charged and thus a differentiation of the air temperatures in the direction of the room is not possible.
- Another disadvantage is that a high specific drive power of, for example, 200 to 400 watts per m 2 is required and these disadvantages lead to the result that high demands on the constancy of the room temperature can not be met.
- the invention is therefore based on the object, an arrangement of the type mentioned above to improve such that the room temperature regulated with high accuracy and speed can be, i. that high demands on the constancy of Room temperature can be met.
- the invention provides an arrangement for the air conditioning of Spaces or the like, in which a plurality of individual Air conditioning units distributed over the room area provided are each separately controlled, i. it is a modular construction of air conditioning units provided each individually dependent on their output actual temperature are controllable.
- the air conditioning units according to the invention are preferably in Connection with a climatic ceiling above the ceiling level distributed and preferably produce a substantially vertical Air flow from top to bottom, such that per unit of air the output air temperature detected detected and is adjustable as needed.
- the output side each air conditioning unit one to a predetermined Setpoint controlled air outlet temperature reached, the is the same across the entire room area, whereby the Air temperature over the entire room area away constant can be.
- the arrangement according to the invention is particularly suitable in connection with machines, manufacturing plants, processing lines etc., where different across the room area Temperatures are being developed, something across the room different temperature, i. different temperature gradients results.
- FIG. Figure 1 shows schematically an illustration of the inventive arrangement in Connection with an application example.
- the inventive Arrangement has several air conditioning units 1, 2, 3, 4, 5 on, either integrated into a climatic ceiling or above a filter cover 6 forming this climatic ceiling is provided.
- each air conditioner in the produces a substantially vertically downward flow of air, as shown by arrows 8.
- Below the general with 9 designated Klimadecke is one or it
- These Machine 11 or the like is thus within a designated 12 space and is from above with a Airflow fed from individual airflow components composed according to the arrows 8 and on the machine 11 or the like is directed.
- the individual air conditioning units 1 to 5 are according to Art a modular system arranged above the filter cover 6,
- Figure 1 is only a view over, for example, the width of the room reproduces the units accordingly several times in Room length are provided, i. it may be essential more than five air conditioning units provided.
- the machine or production line 11 or the like is at the preferred application shown in Figure 1 on a grid-shaped bottom 13 placed, causing the top to bottom bottom air flow through the grid-shaped bottom 13 pass through and laterally along the space 12 along which is divided into individual airflow components, the individual air conditioning units 1 to 5 is returned.
- the different units such as engines, etc. may include occurs in the region of the grid-like bottom 13 an air flow on, which consists of individual components of different temperature can exist or will exist. Consequently lies in the inflow area the individual air conditioning units 1 to 5 an air flow before, the different temperature gradients includes. Purpose and purpose of the arrangement according to the invention it is different at entry side of each air conditioning unit Temperatures to treat the air so that the outlet side the individual air components are practically the same Have temperature values. By the plurality or majority of individual air conditioning units 1 to 5, this can be simple Way and safely achieved, as follows will be described.
- Each air conditioning unit is according to a first embodiment, which is described in connection with Figure 2, from an air cooler 15, a preferably downstream fan 16 and subsequent filter 17, which is part of the in Figure 1 may be designated 6 filter cover.
- a temperature sensor 18 is via a regulator 19 with a control valve 20 in connection.
- the control valve 20 is located in one Coolant circuit between a not shown Refrigeration and the air cooler 15.
- the controller 19 includes a Setpoint generator 22, which optionally has a designated 23 Monitoring unit is variable, wherein the monitoring unit 23 via a connection 24 the actual temperature value receives over the sensor 18.
- FIG. 1 is a diagrammatic representation of the air conditioning unit shown in FIG. 1
- the air cooler 15 controlled to the temperature of the air conditioning unit 1 exiting air to a predetermined setpoint.
- Figure 2 is an example of the structure of the individual air conditioning units 1 to 5 according to FIG. 1
- FIG. 3 shows an embodiment modified relative to FIG. 2 an air conditioning unit 1, with respect to Figure 2 like parts are provided with the same reference numerals.
- the air conditioning unit 1 additionally contains to the components described in connection with Figure 2 a Air heater 26, preferably an electric air heater, the in this embodiment, preferably between the air cooler 15 and the fan 16 is arranged.
- a Air heater 26 preferably an electric air heater
- FIG. 3 shows the temperature sensor or temperature sensor 23 connected to a controller 28, the output side with the Air heater 26 on the one hand and an actual value input 29 of the 19 designated regulator is connected.
- the controller 19 thus receives as an actual value (Controlled variable) not the value of the air temperature at the temperature sensor 23, but the control value of the controller 28.
- the air heater 26 the air cooler downstream and causes a quick readjustment the air which has passed through the air cooler 15.
- Air conditioning units is corresponding in an arrangement 1 shows a temperature control on the output side of the air conditioning units of preferably 20 ° C ⁇ 0.1 ° C in combination with cleanroom systems possible, while the control accuracy according to the invention in locally fluctuating cooling loads also for highly accurate applications with a constant temperature of ⁇ 0.01 ° C can be designed.
- each air conditioning unit 1 to 5 with an air conditioning unit in conjunction with FIG. 3 the controller 28 takes over the regulation of the air temperature.
- the regulator 19 for the air cooler 15 receives the manipulated variable of the controller 28 as an input variable and controls this to a predetermined setpoint, i. of the Air cooler holds just as much cooling power that the electric air heater 26 engaged in a fixed part of his performance remains.
- a higher-order Control or monitoring 23 may be provided, which the individual air conditioning units 1 to 5 scans sequentially or controls and, where appropriate, a change in the setpoints the controller 19, 28 causes and the rest with the individual Temperature sensors 18 is connected.
