Definitions

  • the present invention relates to a method and an apparatus for the ventilation of rooms and especially large rooms, such as workshops and industrial halls, according to the preamble of claims 1 and 4.
  • Such a method and such a device are known from CH- A-179 715 known.
  • the object of the invention is to eliminate these disadvantages.
  • the amount of heat contained in the air mass of the room can be used effectively for heating the rooms in connection with ventilation.
  • the method is carried out favorably when the current pulse of the supply air is increased in proportion to the temperature difference determined.
  • the permissible, predetermined temperature difference e.g. Can be 1 to 3 ° C.
  • the apparatus according to the invention results from the characterizing part of claim 4.
  • the building to be ventilated is identified by reference number 21 and can e.g. a workshop hall or another hall. Both outside air 19 and recirculated air 20 from the room are used for ventilation and for the heating to be carried out at the same time. These air flows are controlled with known control devices 1 and 2 in a manner to be described in more detail below.
  • a filter 3, a heater 4, a blower 9 and a supply air system 12 are provided in the supply air duct.
  • the supply air system 12 is laid in the upper area of the room to be ventilated and directed downwards.
  • a controller 14 regulates the regulating devices 1 and 2 of the outside air flow and the circulating air flow on the one hand by means of the actuating device 13 and on the other hand the heating element 4 by means of the actuating device 5 and the valve 6.
  • temperature sensors 16 and 17 are installed in the lower and upper area of the room, which give their signals to the controller 18. Based on the temperature difference between the upper and lower areas of the room, the controller 18 regulates the supply air flow, e.g. with a controller 10 installed in front of the supply air system by means of the actuator 11, connection a, or by regulating the power of the blower 9 with the controller 7 by means of the actuator 8, connection B.
  • the organs 10, 11 and 12 can be matched, and the regulation of the Current pulse of the supply air can be carried out by increasing the air flow, but also by changing the blowing opening of the supply air system 12.
  • the organs 7, 8 and 9 can form a common unit.
  • the number of supply air systems 12 can of course also be greater than one, including the number of temperature sensors 16 and 17 and the controller 18.
  • a heat sink 22, a heater 23 and a blower 24 can form a separate air recirculation unit, which can be operated in addition to the intake 20 of the air circulation and whose activity, as well as the activity of receiving the air circulation, can be regulated with the controller 14.
  • the minimum air flow of the system and the supply air system is dimensioned according to the ventilation requirements of the room.
  • the temperature of the air in the room is in the desired range, i.e. in a situation where neither heat output nor excessive heat needs to be removed from the room, one tries to keep the air in the room at roof level, e.g. about 1 to 3 ° C, keep warmer than in the work area at floor level.
  • the temperature of the supply air may be the same as that at floor level, i.e. isothermal.
  • the controller 18 of the temperature difference gives the flow controller 10 of the supply air system 12 a command to increase the air flow relatively, whereby (alternative a) the impulse (mass flow x speed) of the supply air system increases and the length of the supply air system increases, which length of throw otherwise increases with increasing temperature difference between the top and bottom of the room would get shorter. In this way, it helps to promote the ability of the supply air system to induce the process heat collected on the roof and to bring it to the work area and to use this heat for heating. If the room has only one controller 18 for the temperature difference, the setting command is passed directly from the controller to the blower, to the power controller 7 (alternative b).
  • the controller 14 in relation to the temperature deviation from the control value, begins to increase the temperature of the supply air by increasing the heating by means of the heating element 4 and its motor valve 6 and actuating device 5.
  • the controller 18 further increases the quantity and the current pulse of the supply air.
  • the maximum air flow of the supply air system, and thus the maximum speed in the blower opening is selected in the situation where the heating requirement of the room is greatest, i.e. both the temperature of the supply air and the volume flow are greatest.
  • this can also be carried out in practice in such a way that a supply air system of this type is selected whose blow size can be adjusted.
  • the room In a situation where the temperature of the indoor air gets too high, i.e. exceeds the setpoint, the room is supplied with a supply air colder than the temperature of the room air.
  • a separate supply air system 22, 23 and 24 or the supply air supplied for this purpose from an existing system is used as the system, in which existing system the regulation of the performance parameters, i.e. the temperature of the supply air and the air flow, and the distribution of the air take place by means of conventionally known technology.
  • Conventional known heat recovery methods are also preferably used in the system.
  • the heat developed by the process e.g. lighting, machines, people and also passive solar heat is first used before moving on to the use of so-called fee-based heat energy.
