Definitions

  • the present invention relates to a building according to the preamble of claim 1.
  • the temperature, wind, rain and humidity can be measured as actuating signals for a control unit which controls the opening and closing of windows.
  • the desired internal temperature is usually used as the control variable.
  • CN 107575119A describes a control that enables windows to be opened and closed depending on the volume, humidity and wind speed, so that on the one hand the window is closed when there is heavy rain or strong wind or loud noise, so that no damage occurs and undisturbed sleep is possible, and on the other hand the window is/remains open when there are no adverse effects from the environment.
  • EP 1225399 A1 describes the equipment of each window with its own measuring unit to determine the local weather conditions.
  • the weather conditions can be used to decide whether or not to ventilate, for example depending on whether opening a window causes local damage or not.
  • EP 3457041 A1 describes a system for ventilating a building, in which the opening of one damper is controlled as a function of another damper. Temperatures from different rooms can also be taken into account.
  • Air exchange describes how often the entire air in a room was exchanged per unit of time, usually one hour. Although possible CN 107575119A The fact that the air exchange can take place under good environmental conditions does not control the extent of the air exchange.
  • a building with a control unit according to the preamble of claim 1 is off WO 00/39506 A known.
  • a school is mentioned in this document (last paragraph on page 13), but one or more control units 33 are provided in several separate rooms (as is always the case in schools). This means that each room can be ventilated individually.
  • each classroom only has the windows on one side of the room; on the opposite side is the door to the corridor, as shown in the attached 1 is shown.
  • the aim of the invention is to provide a building with a control unit that provides a required air exchange by means of natural convection in a well reproducible manner.
  • the rooms are fluidically connected to one another in such a way that, when the windows are open, air can be transported from one side of the building to the opposite side of the building (possibly also to another side of the building).
  • the pressure difference between opposite sides of a building can be determined relatively accurately on the basis of wind speed and wind direction, and this pressure difference also changes only slightly if the wind speed or wind direction changes slightly.
  • the proposed measures thus make it possible to achieve a constant exchange of air by varying the opening angle to reach. This enables a pleasant room and learning climate, especially in schools, but also in other buildings.
  • control unit receives the wind direction and the wind speed as input variables and uses them to determine the differential pressure between the two sides of the building.
  • the measuring device for determining the wind direction and the wind speed is provided at a minimum distance of 10 m, preferably 20 m, from the building, there is the additional advantage that gusts of wind can be detected before they hit the building. This means that the windows can be closed further before the pressure difference in the building increases and drafts occur. Conversely, if the measuring device used to determine the wind direction and wind speed detects a drop in the wind, you will have to wait a few seconds before opening the window further, because the outside pressure at the window also drops with a time lag.
  • a radiator is provided under at least one window, with a grille with a skirt provided above the radiator but below the window as a resistance to reducing the flow of warm air in front of the window is.
  • the radiator prevents the cold air flowing in through the window Air sinks downwards, which would be uncomfortable for people sitting near the window.
  • the grille with apron prevents an excessive heat curtain from forming in front of the window, which would reduce the desired air exchange.
  • Figure 1 shows the floor plan of a highly simplified building to which the present invention can be applied; and 2 shows a tilting window with an arrangement to keep unpleasant cold air inside to avoid winter.
  • the building 11 consists of only two rooms 12, 13, between which a corridor 14 is located.
  • the corridor 14 can be entered via an entrance door 41; from corridor 14 you can reach rooms 12 and 13 via doors 42 and 43 respectively.
  • the doors 41, 42 and 43 are normally closed so that they do not affect the air exchange.
  • Both the space 12 and the space 13 are fluidically connected to the corridor 14 through overflow openings 42 and 43, respectively.
  • These overflow openings 42 and 43 are preferably provided in a suspended ceiling; however, all other known overflow openings can also be used.
  • narrow windows 22 and 32 or 23 and 33 are provided, the opening angle of which can be adjusted by the control device according to the invention. Of course, further windows (in particular for sufficient daylight) can be provided.
  • the present invention is intended in particular for schools where classrooms are provided on both sides of a corridor.
  • a skylight window is controlled to Constantly supplying the classroom with fresh air.
  • An air change of 1.5 h -1 is aimed for.
  • the skylight has a length of 1.5 m and a height of 0.5 m, ie an area of 0.75 m 2 .
  • the spatial geometry of the class is 9 mx 9 mx 3 m, so the class has a volume of 243 m 3 . This means: the volume flow should be 364.5 m 3 /h.
  • the window manufacturers usually measure the air flow through their windows very precisely depending on the opening angle and the pressure difference (or calculate it using simulation calculations).
  • the window given in the example has 0.75 m 2 , ie 7500 cm 2 . This area is divided into 7500 parts T i , each with a side area of 1 cm ⁇ 1 cm, and the flow velocity v i (more precisely, its component in the spatial direction) is determined in this field.
  • the total airflow is then:
  • the result for the window given in the example is: ⁇ b>Table 1 ⁇ /b> 2 pa 4 pa 6 pa 8 pa 10 Pa 12 Pa 3° 165m3 /h 231 m3 /hr 280m3 /h 327 m3 /h 366 m3 /h 403 m3 /h 5° 252 m3 /h 289 m3 /hr 374 m3 /h 413 m3 /h 462 m3 /h 514 m3 /h 10° 304 m3 /h 334 m3 /hr 415 m3 /h 458 m3 /h 521 m3 /h 563 m3 /h 15° 312 m3 /h 347 m3 /h 431 m3 /h 483 m3 /h 541 m3 /h 597 m3 /h 20° 275m3 /h 349 m3 /h 437
  • a heater 4 under the window 22, as is generally the case with many windows anyway. Without further measures, however, the warm air rising from the radiator 4 would form a heat curtain that would not completely prevent the desired air exchange, but would greatly reduce it, which of course is undesirable. For this reason, a grille 3 with an apron is provided over the radiator 4 as a resistance to reducing the flow of warm air in front of the window. It is ideal when the reduced flow of hot air just prevents the cold air 2 from sinking down.
  • the radiator 4 is preferably guided by the outside temperature.
  • the heating output is determined by the flow of cold air 2 so that there are no drafts and the room is not overheated, e.g. at 0°C outside temperature the radiator temperature is kept at 35°C.
