The fold is mainly carried out in the longitudinal direction of the slats, but also the outer edges of the slats are slightly wavy. As part of of the basic idea of the invention can also be used as slats in essentially flat panels or panels folded only in one direction serve.

This ensures that the Sleeve 12 does not go through the hole 15 of the slat. If one or several sleeves 12, in which at least the collar parts 14 in are essentially of the same size, are placed on top of each other, the sleeves 12 do not go into each other, but they overlap Sleeve stacks 17.

Also in In this area, however, there is a little warm air flow in the living room up. Because at least part of such air flow runs through the channels 10 of the heat exchanger 8, is also by the flow of this area transfer thermal energy to the fins 9.

  • the lamellae 9 also had the effect possess that the spread of those developing in the building space Air flow is more intense than with the replacement air valve, that has no slats. Among other things, this is due to that the fins 9 produce a sheet-like flow, the Room air can mix better with the replacement air, among other things. therefore, that building room air also between the sheet-like flows can penetrate. It also follows from such sheet-like flows that that the range of the flows in the building increases or those that form especially between the lowest slats sheet-like flows can advance further than those in one Flow coming flow.

  • the Pressure on the side of the building room is now greater than in the replacement air valve 1 (and outside), there is a tendency for backflow formation, or the air in the building tends to over to exit the replacement air valve 1 into the outside air.
  • the backflow through the barrier 24 of the backflow essentially perfect prevents the backflow barrier 24 from airflow channeling closes and by the backflow generated airflow the barrier 24 of the backflow from the airflow channeling can't bend away.
  • This inside part of the control element of the air flow of the replacement air valve 5 is called the bottom part here and 5.1 is used to indicate this.

  • the controller 5 of the air flow horizontally as close as possible to the mounting frame 3 of the window is pushed, the rear part of the control element covers the air flow 5 the outer channel 6 preferably essentially completely and prevents the flow of replacement air via the outer channel 6 into the Flow channeling 26 of the replacement air valve 1. In this position is the opening 28 in the second flow channel 29.2, the Replacement air into the replacement air valve 1 via the window gap V1, V2 is added.
  • the first position is used advantageously if the outside air is colder than the target temperature of the inside air (so-called Winter position), taking the replacement air before directing it into the building room is heated. Accordingly, the following position is advantageous used when the outside air is warmer than the target temperature the indoor air (so-called summer position), whereby the warming of the Replacement air in the replacement air valve is not necessary. In this summer position can according to the heat exchanger 8 to be recorded from the outside Cool the replacement air slightly, causing the room temperature to rise remains lower due to warm outside air.
  • the replacement air in the window gap V1, V2 in the Replacement air valve is routed, the replacement air is already somewhat in warmed up the gap between the windows. This is because that certain amount of indoor air heat through the window to the outside migrates, which also heats the air in the space between the windows. Part of this heat loss can be absorbed into the replacement air become.
  • the thermal layer on the inner surface of the window is somewhat unlike the situation where the replacement air does not pass through the window space V1, V2 is conducted. This different layer of heat causes the precipitation area of the window to be smaller, i.e. the area where the cold window interior is the flow of the cold Air near the inside of the window towards the floor generated.
