Definitions

  • the invention relates to a method for conditioning and renewing the room air in the lounge area of halls with heights greater than 5 m, conditioning air on the one hand and air, the temperature of which is at least approximately the temperature level in the at least approximately opposite air outlets above the lounge area in two opposing jets Hall corresponds to be blown into the hall.
  • CH-A-580 788 a method for ventilation of halls is known in which fresh or conditioning air is transported and distributed in the room or hall by ejector air flows, the volume of the fresh air flow being large compared to that of the ejector air flow.
  • the object of the invention is to provide a ventilation method for large halls with minimum heights of 5 m - such as Manufacturing, exhibition or sports halls - to be developed to ensure that the occupants feel comfortable and pleasant temperatures and air velocities, and for the implementation of which only systems are required that require as few installations as possible inside the hall, so that e.g. the incidence of light through skylights or work processes - such as Crane journeys - if possible not be hindered.
  • the speed of the room temperature air jet relative to the speed of the conditioning air, which may be heated to a higher temperature is selected such that the room temperature air jet still has a speed in the area of the air outlet for the conditioning air corresponds at least approximately to the rate of entry of the conditioning air into the hall, and that the room temperature air jet is also directed and expanded in such a way that it covers the hall ceiling at least in the last part of its range;
  • a device for performing the method with at least two approximately opposite air outlets, which are arranged at least 0.7 times the hall height above the floor, one of the air outlets being acted upon by a compressed air source, the air at least approximately the same temperature as the hall air promotes, while the other air outlet is connected to a source of conditioning air is characterized in that this air outlet for the conditioning air is preceded by a heat exchanger through which a heating medium flows.
  • an "air roller” is formed by the room temperature air jet, which sets the air content of the hall in a controlled rotational movement.
  • the conditioning air flowing into the hall is mainly deflected into the lounge area of the hall.
  • a room-temperature air jet can be used, for example, to ventilate and condition surfaces or zones of up to approximately 35 x 20 m 2 , so that halls, the length of which does not exceed 35 m, do not require any additional internals for ventilation.
  • "Widths" larger than 20 m can be covered by stringing together several zones.
  • the new method can be carried out with the help of air outlets installed on intermediate fittings.
  • the stressed guidance of the room air jet prevents warm air from building up in the air.
  • the aim is not to have a temperature gradient in the vertical direction over the entire height of the hall.
  • the room temperature air jet reaching up to the ceiling ensures intensive «interference» Ceiling air into the mixed air circulation generated for heating the lounge area.
  • the compressed air source for the room temperature air jet can also be supplied with suitably prepared air from the outside atmosphere or other origin, it is easiest and most economical to use hall air directly for the control jet; it is therefore expedient if this compressed air source consists of a fan that draws in and accelerates the hall air directly. In order to achieve a gradual or continuous change in the pressure potential of this fan, if necessary, the fan can also be equipped with a variable-speed drive.
  • the floor plan of Hall 1 (Fig. 1) is divided into four equal zones 2, which have dimensions of 35 x 20 m 2 .
  • the height H (Fig. 2) of hall 1 is about 9 m.
  • air outlets 3 and 4 are provided opposite one another at a height of approximately 6.5 m.
  • a conditioning air jet is blown into each zone from the air outlet 3 by means of a fan 5 (FIG. 2). This air, which is sucked in as fresh air from the outside atmosphere - possibly via filters (not shown) - passes through a heat exchanger 6 in which it may be heated, before it exits into the hall interior.
  • the heat exchanger 6 is connected via a flow line 8 provided with a flow control valve 7 and a return line 9, in which a shut-off device 12 is provided, to a network for a heating medium, which is not shown in more detail - generally appropriately tempered water.
  • the flow control valve 7 is adjusted by a controller 10, the input signal of which is supplied by a room thermostat 11, which is arranged separately in the area 1A of the people in the hall 1 or in each zone 2.
  • the controller 10 outputs a second signal, which reaches a speed controller 13 for the drive motor, not shown, of a second fan 14. Hall air is sucked in directly by this fan 14, the drive speed of which can assume different values, and is blown out of the air outlet 4 into the hall 1 as a room temperature air jet, as will be described later.
  • Excess and used exhaust air from the individual zones 2 is drawn off via exhaust air devices 15, while 16 in FIG. 1 denotes the roof structure of the hall 1, which is not shown, supports.
  • the curve shown in the upper area shows the position of the valve 7 as a function of the temperature t when a heating medium passes through the heat exchanger 6, the lower level z being for a closed valve and level g being for a fully open valve 7.
  • a setpoint temperature t 1 of, for example, 19 ° C. is first set on the room thermostat 11.
  • the valve 7 on the heat exchanger 6, which is charged with a heating medium is initially fully open.
  • the fan 14 runs at a speed m, so that the flow pattern of FIG. 3 is given.
  • the valve 17 is closed linearly in proportion to the rising temperature. If the hall air temperature continues to rise, the heat generated in hall 1 from internal heat sources is sufficient to meet the demand.
