Definitions

  • the invention relates to a method for favorably influencing the temperature distribution of heated rooms and a system for performing the method, which system either heats the outside air flow or the circulating air flow or the mixed air flow with the help of any energy source and with the help of any heat carrier and / or has a shaft which causes the air to flow due to its specific weight and / or a fan and air injection devices.
  • warm air heating with ventilation is usually used, in which the air is heated to a temperature that is higher than the room air temperature and by outside the lounge zone, i.e. Air inlet openings arranged in the usable zone are blown into the room, directed towards the usable zone.
  • the blown warm air jet loses its speed due to mixing with the room air, and because of the specific weight difference, the mixed air rises, regardless of the original orientation, into the part of the room under the ceiling and pushes the corresponding part of the air there down.
  • This warm air heating with ventilation has the disadvantage that the air will be the warmest in the air space under the ceiling and the coldest in the lower useful zone. Therefore, due to the unfavorable inhomogeneous heat distribution in the room, the heat required due to the heat losses in the room and required to heat the air to the export temperature becomes very large.
  • Air heaters are also known in which the warm heating air and the ventilation air are introduced into the useful zone through the air nozzles arranged in the floor, for example through the air nozzles arranged under the theater seats or at the workplace on the desk.
  • These known solutions have the common disadvantage that the flow velocity of the air introduced into the useful zone is very low, so that the drafts are avoided.
  • the consequence of this is that the warm pickling air introduced rises from the useful zone into the upper air space because of its small specific weight, whereby it hardly mixes with the air in the useful zone.
  • the rising air of a small amount pushes back according to its volume, from the air of the upper air space only a small amount of warm air in the direction of the lower layers.
  • the vertical temperature stratification will be unfavorable and most of the heat energy introduced will not reach its destination, ie the usable zone to be heated.
  • Ls are also known induction air injection devices which intensively mix the room air in the immediate vicinity of the injection with the injected air. These induction air blowing devices cause the air jet to swirl a lot.
  • Hungarian Patent No. 170 824 describes a swirl chamber air outlet
  • Hungarian Patent No. 175 366 describes a radial swirl air outlet.
  • Axial air outlets are also known which contain a vane grille which causes a swirl.
  • an injector space of a special design is arranged in front of the nozzle-like air injection row.
  • induction air injection devices were manufactured for the draft-free introduction of conditioned air with a large temperature difference and are always arranged outside the useful zone, regardless of whether they are used for heating or cooling.
  • a known air injection device that can be used for cooling and air conditioning at the same time is the floor swirl air outlet, which has concentric air injection openings arranged obliquely in the axial direction and is suitable for introducing the air with great induction and with great swirl formation.
  • this air outlet has only been used for intensive mixing or for the free introduction of cold outside air, or air that is colder than the room air.
  • the object of the invention is that it brings about a more favorable temperature distribution and pollutant concentration distribution in the heated room with a favorable fan output.
  • a favorable temperature distribution is to be understood to mean that it should be correspondingly warm in the useful zone and possibly in the air space above the floor level, and that it should be cold in the air space below the ceiling.
  • the invention is based on the knowledge that while the physical laws do not allow the warm air of smaller specific gravity to be in a stable hydrostatic equilibrium state at the bottom and the colder heavier air to be at the top, there is no fundamental or practical obstacle to this in a dynamic equilibrium state .
  • the object is achieved according to the invention with a method for favorably influencing the temperature distribution of heated rooms in that in the upper third of the air space almost horizontally, cooler than the one there with a large impulse and in the lower third of the air space, expediently in the useful zone, warmer Air is introduced as the one there with great momentum and great induction.
  • the air is expediently introduced into the niche space of the air injection device or into the space itself at a speed which is greater than 5 m / s.
  • the cooler air introduced into the upper third of the air space with a large impulse than that there either from outside or from the lower third of the air space is expediently introduced from an air source arranged near the ground level.
  • the method according to the invention is carried out with a plant, which plant either heats the outside air flow or the recirculated air flow or the mixed air flow with the aid of any energy source and with the help of any heat carrier, and / or a shaft which causes the air to flow due to its specific weight, and / or a fan and air injection devices.
  • the essence of this device is that the air blowing devices as air blowing devices of large induction e.g. designed as radial or axial swirl air outlets, or as air outlets with a swirl chamber, or as floor swirl air outlets and are arranged in the lower third of the air space, expediently in the air zone.
  • the method according to the invention can advantageously be carried out with a system which has an air intake opening in the room, an air duct connected to it, and / or a fan, and an air outlet arranged in the room.
  • the system is characterized in that the air intake opening in the lower third of the air space, expediently close to the level of the floor, or in a depression below the level of the floor, the air injection device, on the other hand, is arranged in the upper third of the air space and the air injection device as one Air injection device is formed by large induction.
  • the air injection device of large induction is expediently designed as an air injection device directly connected to the impeller of the fan.
  • the air intake opening 21 of an outside air duct 27 for the fresh outside air is arranged outside 6.
  • a recirculating air duct 28 for the recirculating air opens into this outside air duct 27.
  • the two together form a mixed air duct 29 which is connected to the suction side of a supply air fan 14.
  • the pressure side of the supply air fan 14 is connected to a supply air duct 32 which branches into two parts. One branch leads into the lower third 3, and the other branch into the upper third 2 of the air space 1.
  • an air heater 25 is attached, which is connected to an energy source 8 by means of any heat carrier 9.
  • Air blowing devices 4 are connected to the lower air duct branch 33 and are designed either as a radial swirl air outlet 16, or as an axial swirl air outlet 17, or as an air outlet with a swirl chamber 18, or as a floor swirl air outlet 19. All air blowing devices 4 are air blowing devices of large induction 15 and are arranged in the lower third 3 of the air space 1 or within the useful zone 20.
  • the upper air duct branch 34 is also provided with air injection devices 4, which act as an air injection device of large induction 15, ie as an air outlet with a swirl chamber 18, or as a radial swirl air outlet 16 forms are. These air blowing devices 4 are mounted in the upper third 2 of the air space 1 and the outlet direction 35 of the air flowing out from them is almost horizontal.
  • the air intake opening 21 of an exhaust air duct 30 is arranged in the air space 1, the other end of the exhaust air duct 30 is connected to the suction side of an exhaust air fan 31.
  • the pressure side of the exhaust fan 31 branches into two parts, on the one hand on the recirculation duct 28 and on the other hand on the exhaust duct 36, which opens into the open 6.
  • Flaps 37 are arranged in the exhaust air duct 36, mixed air duct 29 and outside air duct 27.
  • a recuperative or regenerative heat recovery system 26 is installed in each of the exhaust air duct 36 and the outside air duct 27.
  • a heating system 38 is arranged in the air space 1. From the three different systems shown in FIG. 2, the first system is designed from the left in such a way that the air intake opening 21 of a circulating air duct 28 is made in a depression 24 formed below the level of the floor 7.
  • a supply air fan 14 is arranged in the circulating air duct 28.
  • the circulating air duct 28 opens into a radial swirl air outlet 16 arranged in the upper third 2 of the air space 1. The outlet direction 35 of the air emerging from it is almost horizontal.
  • the middle system shown in FIG. 2 is similar to the previous one and conveys the air from the lower third 3 of the air space 1 into the upper third 2.
  • the air intake opening 21 is arranged near the floor level above the floor 7.
  • the circulating air duct 28 is connected to the suction side of the supply air fan 14.
  • the motor 23 of the supply air fan 14 is directly connected to the impeller 22.
  • the air blowing device 4 is connected directly to the air wheel 22.
  • the third system shown in FIG. 2 conveys the air from the upper third 2 of the air space 1 into the lower third 3.
  • the air intake opening 21 of the recirculation duct 28 is therefore arranged in the upper third 2 of the air space 1.
  • the circulating air duct 28 opens into a radial swirl air outlet 16 arranged in the lower third 3 of the air space 1.
  • the outlet direction 35 of the air emerging from it is almost horizontal.
  • the system described in FIG. 1 operates in winter as follows: After fans 14 and 31 start up, the blow-out speed of air-blowing devices 4 is set to a value which is greater than 5 m / s. As a result, these large air induction air blowing devices 15 are made.
  • the temperature distribution of the heated room can be influenced in such a way that into the upper third 2 of the air space 1 through the upper air duct branch 34 and through the air injection devices of large induction 15 connected to this air duct branch 34, that is to say through the radial ones Swirl air outlets 16 and through the air outlets with swirl chamber 18 the outside air or the mixed air resulting from the mixing of the outside air and the recirculating air, which is colder than the air there, is introduced almost horizontally, with a large impulse.
  • the large momentum and the almost horizontal outlet direction 35 of the blown-in air ensure that the cold outside air mixes well with the air of the upper third 2 of the air space 1 and that this upper air space part is cooled uniformly.
  • the type of air inlet mentioned above has a favorable influence on the temperature distribution and prevents the occurrence of a cold air flow.
  • the air introduced through the lower air duct branch 33 is heated by the air heater 25 and into the lower third 3 of the air space 1, expediently into the useful zone 20, by the air blowing devices 4, ie through the floor swirl air outlets 19, through the radial swirl air outlets 16 and axial swirl air outlets 17 with a large impulse and with large induction, blown almost horizontally.
  • the temperature distribution of the heated room is influenced even more favorably.
  • the introduced thermal energy quickly loses its speed when it mixes well in the occupied zone and transfers the thermal energy primarily to where it is necessary. Under the effect of the circulation of the mixed and slowed air within the room and the warm exhaust of the upper air space, a wrong vertical temperature distribution arises as a dynamic state of equilibrium.
  • the recuperative or regenerative heat recovery system enables part of the heat energy content of the exhaust air to be used to heat the outside air.
  • the temperature distribution is favorably influenced by the fact that the cold outside air filtering into the air space through the joints and openings, which due to its specific weight is in the lower part of the useful zone 20, near the Ground level is located, collected in a trough 24 formed below the floor level and is suctioned off from there or from near the floor level.
  • warmer air can flow downwards from above.
  • the cold air is introduced into the upper air space with a large impulse, which on the one hand cools the air in the upper air space and on the other hand creates a high-intensity internal air circulation with this cooling effect, which reduces the temperature distribution and pollutants. Concentration distribution and the temperature distribution in the room homogenized.
  • the temperature distribution in the room is influenced in such a favorable manner that the warm air located in the upper third of the air space 1 is extracted and instead of this air cooler air flows upward from the lower third 3 of the air space 1.
  • the warm air drawn off at the top is mixed with great momentum and with great induction of the cold air located in the lower third 3 of the air space 1. This creates an air circulation that homogenizes the harmful concentration distribution and the temperature distribution.
  • the attribute of a large induction attributed to the air blowing device 15 essentially means that this device is capable of intensively mixing the room air in the blowing area with the blown air.
