  • the Source ventilation on the advantage that in the heating mode to a cold air drop the window is prevented. Heat losses through warm air, which escapes through the window, can be accepted as low become.
  • the aforementioned mixed-source ventilation leads to a lower summer Temperature stratification compared to a pure source ventilation, since a room air admixture takes place. A risk of short circuit can be prevented by appropriate steering of the air.
  • a cold air drop occurs in heating mode prevents the windowpane. It may preferably be a shield take place through compartments that are more effective than with the source ventilation.
  • the heat losses through warm air escaping through the window can be kept very low, so they do not interfere Appear appearance.
  • Figures 1 and 2 where ceiling fan coils are used, results in the summer the advantage that warm ceiling air is sucked in, what results in a higher cooling capacity. It turns out a very small Temperature stratification on. In winter you have to pay attention that there is no excessive cold air drop to prevent accumulation of to have cold outside air on the ground. It is also important to that hot air does not escape in too much through the window, to prevent high heat losses.

Furthermore, it is additionally or alternatively possible, the internal temperature, especially in the floor area, to be sensed to to avoid low soil temperatures.
  • the aim of the window ventilation is the Cover fresh air demand of the room. This is cost effective Fresh air due to the window ventilation used to improve the room climate is aftertreated.
  • regulatory examples include the following: The fresh air requirement depends on the number of people in the room and can be pretended accordingly.
  • the controller and / or Regulation then provides the appropriate outside air opening area one.
  • the pressure conditions on the facade of the Outside air opening having space and / or the pressure conditions taken into account at the outside air opening. Is a high facade pressure before, so a small opening is set. It remains the fresh air requirement constant. At low facade pressure is a set large outside air opening, where also the fresh air requirement is kept constant.
  • suction or rain the outside air opening becomes closed and optionally another outside air opening, in particular another window, automatically opened, at the overpressure exists. Of course, this procedure can only be done be carried out when the conditions mentioned are present.
  • Air conditioners Depending on the temperature of the fresh air (outside air) be fan of the Air conditioner and volume flow of the cooling and / or heating means of Air conditioner by appropriate valve adjustment or - at central, air conditioners - the dampers and volumetric flow controllers for the air and the valves for the cooling and / or Heating medium activated. Also conceivable is a 4-conductor system, the can both heat and cool, and in each case a control or regulation of the corresponding valves takes place.
  • the controller or controller may have a map, in which a target value is set. By the of the sensors followed by measurement of temperature and / or pressure and / or speed the air at the window as well as the room temperature becomes an actual value is determined. Now window drive, valves of or the heat exchanger and speed of the fan or fans are controlled, to get to the required target value.

  • Outside air 26 passes through the outside air opening area 8 in the upper part of the window 4 in the room 1 a and meets the coming from the heat exchanger 17 cooled room air 29. There is a mixing and the mixed air sinks according to the oblique arrows 53 in the occupied zone of Room 1. Over the side areas of the opened window 4 can Room air 29 leave the room 1.
  • FIG. 18 differs from the 17, characterized in that the ceiling 10 to the facade wall 2 a Free space 55 leaves, which forms an air inflow channel 56. hereby It is possible that by the outside air opening cross section. 8 incoming outside air at least partially into the Heilzuströmkanal 56 enters and passes to the heat exchanger 17 and passes through this. Otherwise, the statements apply in the same way as they have already been explained for Figure 17.
