- the described devices 1 are switchable between two modes, which are referred to as winter operation and summer operation. These two modes are now explained in more detail:
- the device 1 transmits moisture and heat contained in the exhaust air to the outside air.
- the first fan 6 conveys outside air into the room and the second fan 7 conveys exhaust air out of the room.
- the first blower 6 may be located anywhere in the first duct 20, the second blower 7 may be located anywhere in the second duct 21.
- the third fan 23 circulates the air flow in the closed air circuit 22.
- the dehumidifying and cooling device 19 is turned off, i. the air passes through the dehumidifying and cooling device 19 without giving off moisture or heat.
- the device 1 transmits a part of the moisture contained in the outside air to the exhaust air and transmits part of the heat of the outside air to the exhaust air, that is, the cooler exhaust air is used for cooling the warmer outside air.
- the transmission of moisture from the outside air to the exhaust air by means of the two moisture exchangers 11 and 15, which are connected to each other via the closed air circuit 22. Because the exhaust air can not absorb as much moisture as required, in the embodiment according to FIG. 1, the air stream circulating in the air circuit 22 is additionally dehumidified, ie the dehumidifying and cooling device 19 removes the portion of the air flow circulating in the air circuit 22 Moisture which the exhaust air can not absorb and which must be removed so that the supply air has the desired humidity.
- the dehumidifying and cooling device 19 removes the portion of the air flow circulating in the air circuit 22 Moisture which the exhaust air can not absorb and which must be removed so that the supply air has the desired humidity.
- the exhaust air is additionally dehumidified, ie the dehumidifying and Cooling device 19 withdraws so much moisture from the exhaust air that the moisture removed in the moisture exchanger 11 from the outside air can be completely transferred to the exhaust air by means of the moisture exchanger 15. It is also possible to dehumidify both air streams.
- the first fan 6 conveys outside air into the room and the second fan 7 promotes exhaust air out of the room.
- the dehumidifying and cooling device 19 is in operation, so that the air at the outlet of the dehumidifying and cooling device 19 is drier and cooler than the air at the inlet of the dehumidifying and cooling device 19.
- In the closed air circuit 22 circulates air, which is offset depending on the design of the dehumidifying and cooling device 19 either from the third fan 23 or from the dehumidifying and cooling device 19 in flow.
- Cooling device 19 which is traversed by an air stream 38 to be treated.
- the dehumidifying and cooling device 19 has a cooling block 36 and, optionally, a subsequent heat block 37.
- the air stream 38 is cooled to a temperature below the dew point so that at least some of the moisture contained in the air condenses out as water.
- the resulting heat is supplied as described above by means of the conveyed through the line 26 air flow at the second outlet 5 (Fig. 1) of the exhaust air. If the heat block 37 is present, a portion of the resulting heat is supplied directly to the exhaust air and the remaining portion of the resulting heat directly or via a line 32 to the heat block 37 and then the exhaust air to reheat the exiting the cooling block 36 cold air.
- FIGS. 7 to 10 illustrate various examples of the dehumidifying and cooling device 19, all of which also include the heat block 37.
- the heat block 37 may also be omitted. In this case, the heat generated is supplied to the exhaust air.
- Example 1 In the example shown in FIG. 7, the cooling of the air stream 38 flowing through the dehumidifying and cooling device 19 takes place in the cooling block 36 by means of at least one Peltier element 39.
- two Peltier elements 39 are shown, which have a cold wall 40 and a warm wall 41.
- the temperature of the cold wall 40 is cooled by supplying electrical energy, wherein at least the last Peltier element seen in the flow direction of the air flow 38 is cooled to a value which is below the dew point of the inflowing air.
- Air flow 38 cools, with moisture contained in the air stream 38 condensing on the cold wall 40 as water as soon as the temperature of the air flow 38 drops below the dew point.
- the water is supplied via a line 42 to a reservoir 43 or discharged directly to the environment.
- the resulting heat during cooling of the air stream 38 and the condensation of moisture, as well as the Peltier elements 39 supplied electrical energy, which is also converted into heat, passes to the warm wall 41.
- a portion of this heat is for example via a line 44 to the heat block 37th supplied and transferred in the heat block 37 by means of a heat exchanger 45 to the air stream 38 to heat the air stream 38 in the heat block 37 to a desired temperature.
- the remainder of the heat is released to the air flowing through the conduit 26. This is possible because the temperature of the warm wall 41 is higher than the temperature of the outside air.
- the dehumidifying and cooling device 19 has a plurality of Peltier elements 39, on which the passing air is cooled and dehumidified.
- the air flow 38 is along the cold side of the
- Peltier elements 39 and then guided along the warm side of at least one of the Peltier elements 39. That Here, the heat block 37 is formed by the warm side of this at least one Peltier element.
- the dehumidifying and cooling device 19 In winter operation, the dehumidifying and cooling device 19 is usually not in operation, since the outside air is relatively dry and does not have to be dehumidified.
- the Peltier elements 39 present in this example can be used to heat up the air stream flowing through the dehumidifying and cooling device 19. The current flowing through the Peltier elements 39 then flows in the opposite direction, so that now the wall 40 is heated and the wall 41 is cooled.
- the cooling block 36 comprises a compressor 46, a heat release chamber 47, a turbine 48 and a Condensation chamber 49, wherein the drive shafts of the compressor 46 and the turbine 48 are coupled together.
- the compressor 46 mechanically compresses the air, thereby heating the air.
- As the relatively hot air flows through the heat release chamber 47 it heats the heat release chamber 47 to a temperature well above the local ambient temperature so that the heat release chamber 47 can deliver heat to the environment.
- the resulting heat is dissipated by the flowing through the line 26 outside air.
- the supplied outside air thus cools the heat dissipation chamber 47. In this way, the air flow 38 heat is removed.
- the air stream 38 subsequently flows through the turbine 48, it drives the turbine 48.
- the air flow 38 must perform as much mechanical work when driving the turbine 48, that it is cooled to a temperature below the dew point.
- the cold air therefore cools the condensation chamber 49, so that in the condensation chamber 49 moisture condenses out as water and is collected via a line 42 in a reservoir 43 or discharged directly to the environment.
- the air stream 38 leaves the condensation chamber 49, it is cold and dry.
- a portion of the heat accumulating in the heat release chamber 47 is supplied to the heat block 37, for example via two heat exchangers 45 and 52 interconnected by a conduit 44.
- Cooling device 19 a compressor 46 and a vortex tube 53.
- the compressor 46 compresses the air flow 38 and thus increases the pressure of the air, so that the air flow 38 flows into the vortex tube 53 at high speed. In this case, the temperature of the air stream 38 increases. A portion of the heat is removed by means of a heat exchanger 54 via the line 26.
- the vortex tube 53 separates the air flow into a hot air flow and a cold air flow and is designed so that the temperature of the cold air flow is below the dew point, so that the moisture contained in the cold air flow condenses out as water.
- the cold air flow and the hot air flow are performed in separate lines 50 and 51, on the one hand condense the water and on the other hand the hot air flow, for example by means of another heat exchanger 55, heat are removed can.
- the dehumidified cold air flow and the hot air flow are then reunited before they leave the dehumidifying and cooling device 19.
