  • the invention relates to a room ventilation device (RLT device) according to the type specified in claim 1 and a method for using such a room ventilation device according to the type specified in claim 24.
  • RLT device room ventilation device
  • Air conditioning systems in particular air conditioning systems, with the maximum possible air treatment functions, such as filtering, heating, heat recovery, moisture recovery, cooling, adiabatic humidification for pre-cooling and dehumidifying, require a lot of thermal energy and also electrical energy during operation. These energy needs, which are incurred in each case individually equipped with air treatment parts devices are significant.
  • the high electrical energy consumption of such devices is due to the fact that several fans for the supply air and exhaust air both in the sewer network and in the room ventilation device even for the two connected air conveyor sections of supply and outdoor air, and for the exhaust air and exhaust air high Have to overcome air resistance.
  • the internal air resistance is of great importance.
  • a saving of electrical and thermal energy for air delivery and room cooling can best be done in a mixed air operation with the use of mostly cold outside air.
  • sufficient filtering of the circulating air used must take place, in particular if persons are present in the room supplied by a room ventilation device.
  • a good dust filter and high demands on the indoor air quality in addition a special filter, such as an activated carbon filter, or multiple filter stages are required.
  • the known conventional ventilation equipment in which the air treatment parts are all arranged in series in the air treatment path from the incoming outside air AUL to the exiting supply air ZUL, but this significantly increases the air resistance, which has to overcome the supply air fan. For the reasons mentioned above, therefore, air-conditioning appliances with mixed air operation are only rarely used in rooms in which people are present.
  • DE 20208391 U1 also describes in a supply air duct arranged in parallel air treatment parts, such as heating module, heat recovery module and cooling module. They are used individually as needed. However, this solution has disadvantages because the heat recovery can not be used optimally and beyond a very large housing cross-section is needed. Moreover, nothing is said there about a special partial flow control, with the particular drive energy can be saved.
  • the object of the invention is to reduce the total energy demand of various ventilation equipment of different shapes for a variety of uses and in particular the electrical energy requirements for air transport on the components of ventilation equipment so that these devices can be used in different climates and none Disadvantages compared to conventional known room ventilation devices in the thermal air treatment and air treatment arise.
  • the object is achieved by a room ventilation device according to the features of claim 1 and by a method for using such a room ventilation device according to claim 24.
  • a proposed room ventilation device has a housing which has at least one opening for an air supply and at least one opening for an air discharge.
  • the main air treatment modules for the supply air treatment and exhaust air utilization / treatment are distributed in different flow paths in the housing.
  • the flow paths at least two flow paths are parallel, wherein in one of these flow paths, a first air treatment module is provided.
  • the two flow paths can be acted upon by flow control devices according to demand with partial volume flows.
  • the parallel flow paths unite in one mixing point.
  • the uniting partial volume flows are controllable by means of a measuring control control module such that, with the necessary thermal power control, the total power for the air treatment in connection with the deflection to partial air flows is regulated by means of an added energy.
  • two further parallel flow paths connect to a mixing point, wherein in one of the two flow paths there is a second air treatment module, which can be bridged with a bypass flow path.
  • This second air treatment module is additionally flowed through by an independent flow path which is independent of the resulting flow path from the mixing point.
  • the independent flow path can be fed, for example, from circulating air, exhaust air or outside air.
  • the second thermal air treatment module can be used thermally in the air circulation path as well as in an outside air / mixed air flow path or only flowed through. If it is used in the air circulation, which is the rule and there only a small proportion of circulating air is used for the supply air, it usually has no effect on the resistance of the supply air fan.
  • An analog arrangement scheme is also conceivable for the exhaust air / exhaust air use or exhaust air treatment.
  • the room ventilation device according to the invention makes it possible, regardless of whether it is a ventilation system, ventilation system, ventilation system, partial air conditioning or full air conditioning, a reduction of the total internal resistance for air delivery, although a thermal air treatment is carried out according to the prior art.
  • the ventilation system allows; promote different partial flows through the parallel flow paths.
  • the air treatment modules are designed for the treatment of the entire volume flow, but are usually acted upon only with partial volume flows. Since the resistance of an air treatment module reduces with decreasing volume flow, the total internal resistance is lowered.
  • Another advantage results from the fact that it is available as a parallel flow path by appropriate control and regulation of each module, regardless of whether it is currently used thermally. This results in a further reduction in resistance.
  • the air treatment modules can, depending on the individual task in different ways, d. H. parallel and / or partially in series. Due to the possibility of parallel use, the inner air flow resistance, the so-called, pressure of the ventilation and air conditioning unit is greatly reduced, which results in a significant energy saving, as a result of which the required drive power of the fan drops enormously. It is basically irrelevant whether it is a mixed air unit with single or multiple recirculation use or a pure outdoor air treatment unit or exhaust air unit.
  • a third air treatment module is provided in the branch which is parallel to the first thermal air treatment module.
  • the controlled deflection on two air paths with the same resistance P with the combined power control of the component is thus more energy-saving than, for example, the flow through a cooling register with only thermal power control and when not using this cooling register, the deflection to a bypass path, which is often because construction height at a Ventilation device must be saved, at least P / 2 has.
  • the first and the third thermal air treatment module are formed in opposite thermal function, which never have to perform an air treatment at the same time.
  • thermal capacity control of each individually required, for example, heat recovery register for heating purposes and cooling register is therefore best regulated both by deflection of the air currents to the other, not thermally just required component as well as by controlling the cooling or heating medium to the just required air treatment component.
  • the independent flow path is fed by the outside air.
  • the second thermal air treatment module can be operated both serially and genuinely parallel to the first thermal air treatment module.
  • the room ventilation device may be designed as a recirculation unit. It has at least two openings for the air supply and at least two openings for the air discharge.
  • the air supply is connected in this case to the exhaust air and to the outside air, the exhaust air and supply air to the air discharge. It forms a first main flow path from outside air to supply air and a second main flow path from exhaust air to exhaust air.
  • at least one circulating air flow path is provided, which branches off a partial volume flow from the exhaust air outlet air flow path into the outside air supply air flow path.
  • a suction-side opening of circulating air directly in front of the fan saves energy as well as thermal energy.
  • the circulating air for thermal reasons is the most effective heat recovery. In accordance with heat insulated buildings can be omitted, in particular in combination with additional heat recovery in the air conditioning unit, if necessary, even a reheating by corresponding heating coil with energy from the outside.
  • the circulating air flow path merges into the previously described independent flow path.
  • the partial flow which is diverted, for example, from the exhaust air outlet air flow path, flows through here with or without prior filtering the second air treatment module and can be treated there accordingly.
  • the air diverted from the circulating air can therefore be mixed with the volume flow coming from the first main flow path. This reduces the necessary volume flow in the main flow path by the amount required by the circulating air. good part. Since the resistance of the air treatment components decreases with decreasing volume flow in the square of the rate of increase, resulting from the lower outside air volume flow, a strong reduction of the flow resistance before the mixing point, in which circulating air and outside air mix.

  • the resistance of the air treatment module arranged in the circulating air path does not have any effect on the fans.
  • the fan In a comparable conventional RLT device with series arrangement of the components, the fan must constantly overcome the suction side partial resistance of 3 x P.
  • the first thermal air treatment module with an outside air content of 66.6% flows through the supply air and the second thermal air treatment component with about 33% circulating air. This results in a total resistance of 0.44 x P.
  • the circulating air is shut off and the fresh air content of the supply air is therefore 100%.
  • the entire volume flow is conveyed only via the first thermal air treatment module, which leads to an internal resistance of the air handling unit of 1 x P.
  • the first thermal air treatment component is flowed through in series with the second thermal air treatment component, resulting in a resistance of 2 ⁇ P.
  • the device according to the invention can be operated as needed with a significantly lower resistance in the annual average.
  • the air supply of the ventilation unit can be done by the outside air. This implies that the parallel branches of the inventive arrangement can fork in the outside air flow path.
