Definitions

  • the invention relates to an arrangement for air conditioning Rooms or the like according to the preamble of the claim 1.
  • an air flow which cannot be differentiated over the room surface is blown into a room via a ceiling, preferably a filter ceiling, after the air flow has been appropriately cooled or heated via an air conditioning unit.
  • a single unit for air conditioning is thus used, which also contains a blower device, so that a circulation of the air flow from the air conditioner through a filter cover through the room and to the air conditioner is carried out.
  • a disadvantage of such an arrangement is the comparatively high pressure loss as a result of high resistances, for example as a result of a plurality of throttle valves which are arranged in the filter ceiling and are intended to produce a uniform air flow over the surface of the room.
  • Another disadvantage of this known arrangement is that the filter ceiling is supplied with one and the same air flow, ie with air at the same temperature, and thus it is not possible to differentiate the air temperatures in the direction of the room.
  • 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 cannot be met.
  • the invention is therefore based on the object of an arrangement to improve the type mentioned in such a way that the room temperature regulated with high accuracy and speed can be, i.e. that high demands on the constancy of the Room temperature can be met.
  • the invention provides an arrangement for air conditioning Rooms or the like in which a plurality of individual ones Air conditioning units provided over the area of the room which are regulated separately, i.e. it is a modular structure of air conditioning units is provided, each individually depending on their actual output temperature are adjustable.
  • the air conditioning units according to the invention are preferably in Connection with a climate ceiling above the ceiling level distributes and preferably produces a substantially vertical Air flow from top to bottom, such that per air conditioning unit the air temperature present on the outlet side is recorded and can be regulated as required. This way the output side each air conditioning unit one to a given one Setpoint adjusted air outlet temperature reached that is the same across the entire surface of the room, making the Air temperature kept constant over the entire area of the room can be.
  • the arrangement according to the invention is particularly suitable in connection with machines, manufacturing plants, processing lines etc., in which different across the room area Temperatures are developed, which is one across the room different temperature, i.e. different temperature gradients results.
  • FIG. 1 shows schematically a representation of the arrangement according to the invention in Connection with an application example.
  • the arrangement has several air conditioning units 1, 2, 3, 4, 5 that either integrated into a climate ceiling or above a filter ceiling 6 forming this climate ceiling are provided.
  • each air conditioner is a generates essentially vertical downward air flow, as shown by arrows 8.
  • a production line or the like which is indicated by the reference number 11.
  • This Machine 11 or the like is thus inside one designated by 12 and is from above with one Airflow fed, which consists of individual airflow components assembled according to the arrows 8 and on the machine 11 or the like is directed.
  • the individual air conditioning units 1 to 5 are in accordance with Art a modular system arranged above the filter ceiling 6,
  • Figure 1 is only a view of, for example, the room width reproduces and the units accordingly several times in Room length are provided, i.e. it may be essential more than five air conditioning units are planned.
  • 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, which makes the top to air flow below through the grid-shaped floor 13 pass through and along the side of the room 12 upwards can circulate, after which it is divided into individual air flow components, the individual air conditioning units 1 to 5 is fed again.
  • an air flow that has different temperature gradients includes.
  • the purpose of the arrangement according to the invention it is different for each air conditioning unit on the inlet side Temperatures to treat the air so that the outlet side the individual air components are practically the same Have temperature values.
  • each air conditioning unit consists of 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 can be designated 6 with filter cover.
  • a temperature sensor 18 stands above a controller 19 with a control valve 20 in connection.
  • the control valve 20 is in one Coolant circuit between a not shown Refrigerator and the air cooler 15.
  • the controller 19 contains one Setpoint generator 22, possibly via a designated 23 Monitoring unit is variable, the monitoring unit 23 the actual temperature value via a connection 24 receives via the sensor 18.
  • FIG. 2 is an example of the structure of the individual air conditioning units 1 to 5 according to FIG. 1.
  • Figure 3 shows an embodiment modified from Figure 2 an air conditioning unit 1, compared to FIG same parts are provided with the same reference numerals.
  • the air conditioning unit 1 additionally contains to the components described in connection with Figure 2 Air heater 26, preferably an electric air heater, the in this embodiment preferably between the air cooler 15 and the blower 16 is arranged.
  • Air heater 26 preferably an electric air heater
  • 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 controller is connected.
  • the controller 19 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 cooler 15 works comparatively sluggishly, is at the embodiment of Figure 3, the air heater 26 the air cooler downstream and causes a quick readjustment the air flowing through the air cooler 15.
  • Air conditioning units is corresponding with 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 possible with clean room systems, while the control accuracy according to the invention with locally fluctuating cooling loads for high-precision applications with constant temperature of ⁇ 0.01 ° C can be designed.
  • the controller 28 When in accordance with the present invention as used in conjunction with FIG. 1 describes each air conditioning unit 1 to 5 with an air conditioning unit in conjunction with FIG. 3 is provided, the controller 28 the regulation of air temperature.
  • the controller 19 for the air cooler 15 receives the manipulated variable of controller 28 as the input variable and regulates it to a predetermined setpoint, i.e. of the Air cooler holds just as much cooling capacity as the electric air heater 26 engaged with a fixed part of his performance remains. Rapid changes in air inlet temperature to the air conditioning units 1 ff. are from the air heater 26, the air cooler 15 regulates slow changes out.
  • a superordinate one Control or monitoring 23 may be provided, which the individual air conditioning units 1 to 5 sequentially scanned or controls and, if necessary, a change in the setpoints the controller 19, 28 causes and the rest with the individual Temperature sensors 18 is connected.
