Definitions

  • the present invention relates to a method for ventilation especially of large rooms, such as workshops and industrial halls.
  • One purpose of the invention is to eliminate this disadvantage.
  • the method according to the invention is characterized in that the pulse of the supply air flow is regulated on the basis of the difference between the temperature occurring in the upper part of the room and the temperature occurring in the lower part such that when the temperature difference exceeds a predetermined value, the momentum of the supply air flow is increased to maintain the desired temperature distribution in the room.
  • 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 in such a way that the impulse of the supply air flow is increased in proportion to the determined temperature difference.
  • the impulse of the supply air flow is increased in proportion to the determined temperature difference.
  • the invention also relates to an apparatus for carrying out the ventilation process, which apparatus comprises a supply air system, a fan feeding this system, a heater mounted in front of the fan, a regulating device for the outside air flow and a regulating device for the circulating air, and one the working height installed temperature sensor with controller for controlling the said regulating devices and the heating device, the supply air system being installed in the upper part of the room to be ventilated and at least essentially directed downwards.
  • the apparatus is characterized in that temperature sensors are installed in the upper part and in the lower part of the room, which are connected to a common regulator, that the regulator for the supply air flow is connected to the regulator, and that the regulator is arranged in such a way that it controls the Control of the supply air flow based on the temperature difference detected in the upper and lower part of the room so that when the temperature difference exceeds a predetermined value, the pulse of the supply air flow increases.
  • the building to be ventilated is identified by reference number 21 and can e.g. be a workshop or other hall.
  • both air 19 taken from outside and circulating air 20 from inside the room are used.
  • These air flows are regulated with known regulating 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 installed in the upper part of the room to be ventilated and directed downwards.
  • the controller 14 regulates the regulating devices 2 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.
  • the regulator 18 regulates the supply air flow, for example with a regulator 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 regulator 7 of the actuator 8, connection b.
  • the organs 10, 11 and 12 can be fitted together and the regulation of the pulse for the supply air flow can be carried out by increasing the air flow, but also by changing the injection 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.
  • the heat sink 22, the heating element 23 and the blower 24 can design a separate circulating air unit which can be operated in addition to the intake 20 of the circulating air and whose activity, as well as the activity of taking the circulating air, 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. to be kept about 1 to 3 ° C warmer than in the working 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 throw length of the supply air system increases, which would otherwise be shorter with increasing temperature difference between the upper and lower part of the room.
  • the ability of the supply air system to induce the process heat collected on the roof height and to bring it to the work area and to use this heat for heating is contributed. 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 begins to increase the temperature of the supply air in relation to the temperature deviation from the control value 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 pulse of the supply air.
  • the maximum air flow of the intake air system, and thus the maximum speed in the bladder opening is selected in the situation where the Heatin g s collar of the space is the largest, that is, both the temperature of the feed air and the volume flow are greatest.
  • this can also be carried out in practice by selecting such a supply air system whose blow size can be adjusted.
  • a supply air is supplied colder than the temperature of the room air into the room.
  • 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 are carried out by means of conventionally known technology.
  • the heat developed by the process e.g. lighting, machines, people and also passive solar heat
  • the heat developed by the process is first exploited before moving on to the use of so-called chargeable thermal energy.
