Definitions

  • the invention relates to an air conditioner according to the preamble of claim 1. Furthermore, the invention relates to a method according to the preamble of claim. 9
  • a pressure difference measuring device which receives a pressure difference between the outlet and the inlet air of the room unit and measures a supply air pressure difference with respect to the duct system.
  • the opening angle of the respective flap depends on the output signal of the pressure difference measuring device.
  • the invention has for its object to improve an air conditioner of the type mentioned so that line losses are reduced, with a remedy against an uncomfortable perceived noise is possible.
  • the invention enables virtually active volumetric flow control, which therefore no longer requires passive volumetric flow controllers over solutions with adjusting flaps.
  • each supply air unit is provided with a differential pressure sensor, which is connected to a controller comprising an electrical control element for controlling a fan motor of the fan.
  • a controller comprising an electrical control element for controlling a fan motor of the fan.
  • controller is equipped with an external setpoint input.
  • a pressure change with regard to a supply request for example a desired setpoint temperature or setpoint differential pressure
  • An external actuator connected to the setpoint input such as a rotary potentiometer, Tap-changer or the like with control knob, can then be connected to the setpoint input, so that from the respective cabin from an individual temperature or flow setting is adjustable.
  • a remote control using a Fembedienilless or other solutions are also possible.
  • each supply air unit comprises an air rectifier. This can prevent air from being sucked out of the cabin and conveyed back into the main duct when, for example, other fans of other cabs are operated at a relatively high speed. Such an arrangement is particularly favorable when using axial fans.
  • an axial fan is favorable if a high volume flow is to be possible. This is advantageous, for example, in large cabins.
  • an axial fan is very quiet.
  • a radial fan is better if a large pressure difference would be overcome. So quite different types of fans along the main channel can be used.
  • an air supply device is used, which is designed as an induction device.
  • the air supply device comprises a lower air outlet, an electric air heater and / or a cooler and a top-mounted primary air connection with a fan. It can be accomplished optimally heating and / or cooling of the cabins.
  • Fig. 1 shows an air conditioner 1 of a ship. This is used for the air treatment of cabins but basically also other ship rooms. For the sake of simplicity, however, cabins are used.
  • the air conditioning system 1 comprises a central air supply device 2. This consists of a central air conditioner for cooling and / or heating the individual ship cabins.
  • the air supply device 2 also comprises a central fan for conveying air in a main channel 3, which is connected to this device 2.
  • the main channel 3 has a relatively large length of, for example, at least over 100 meters or even a multiple thereof.
  • a ship may for example be a cruise ship with a significant number of ship cabins, in particular at least 200 cabins or significantly more.
  • the main channel 3 along the entire length preferably always has the same cross section.
  • the main channel 3 is provided with a plurality of branch channels 4 for air conditioning in the various cabins.
  • Each branch channel 4 is provided with a supply air unit 5, wherein an air outlet to the corresponding cabin is present.
  • each supply air unit 5 is provided with a fan 6, which conveys a volume flow into the cabin.
  • Each fan 6 is powered by the electrical system of the ship.
  • each fan 6 generates just that much differential pressure, that an air flow in the room is promoted with little or no pressure.
  • the arrows in Fig. 1 indicate only the volume flows V 1 to V 4 of the cabins, but with a significantly higher number of branches are present.
  • each supply air unit 5 has an intake port 7 connected to the respective branch passage 4 and an exhaust port 8 leading to the car.
  • each supply air unit 5 is provided with a measuring probe, in particular a differential pressure sensor 10. This is connected to an electric control element comprehensive regulator 11 for controlling a fan motor 12 of the fan 5.
  • a control element for controlling each control element is suitable, which compensates for dynamic pressure fluctuations. To control pressure fluctuations, a fixed differential pressure setpoint can be taken into account.
  • the controller 11 may be provided with an external setpoint input 13. This input can be used to set a desired temperature or another supply request.
  • an individual pressure difference ⁇ p can be set for the respective cabin. For example, if a high volume flow of cold air to be promoted, then a higher pressure difference is to be specified, as if only a small volume flow of cold air to flow into the cabin.
  • the fans 5 used are fans of relatively low power or smaller dimensions. They have a much smaller performance compared to the central fan. Such a fan rated power can be for example 1 to 10W.
  • Fig. 2 In the air flow control according to Fig. 2 is used as fan 5, an axial fan.
  • the sensor 10 is located in the flow path in front of the fan 5, wherein between the sensor and the fan 5, an air rectifier 15 is installed so that air can flow only in the same direction.
  • the supply air unit 5 according to Fig. 3 a radial fan in which air is sucked laterally and conveyed through the fan outlet opening 14.
  • the sensor 10 is arranged behind the fan 5.
  • the Fig. 4 shows the air supply device in a cabin, which consists of a fan 17 connected to a primary air connection 16 of the central air conditioner.
  • This air supply device is designed as an induction device.
  • the air outlet 18 of the device below is the air outlet 18 of the device, while the primary air connection 16 is at the top. Above the air outlet 18 is an electric air heater 19 for heating the cabin. In addition, a cooler 20 is provided, which serves for cooling and dehumidification.
  • a central air flow is practically divided into several branch streams conducted to the cabins. There is a pressure reduction at each branch flow through the corresponding fan 5, in such a way that a differential pressure is built up and an air flow is conveyed into the cabin with little or no overpressure.
  • the invention is not limited to this example.
  • a skyscraper or the like can be conditioned by the system 1 according to the invention.
  • the supply line in the branch channel 4 can also belong to the supply air unit 5, so that the fans 6 can also be arranged in the region of the supply line.
