The present embodiment provides a total heat exchanger, wherein the exchanger body 1 of the total heat exchanger is provided with an exhaust passage 11 for discharging indoor air to the outside, and similarly, an intake passage 12 for supplying fresh air to the inside.
Meanwhile, the exchanger main body 1 is also provided with a heat exchange core to realize the mutual heat exchange between the air flowing through the air inlet channel 12 and the air flowing through the air outlet channel, so that the heat or the cold can be recycled in a high-efficiency and energy-saving manner, the fresh air entering the room can be preheated or precooled, and the purpose of reducing the indoor temperature fluctuation can be finally realized.
In addition, fans are respectively arranged on the exhaust passage 11 and the intake passage 12 to realize the delivery of the air flow. For the specific structural form of the exchanger main body 1, reference may be made to the main body structure of the total heat exchanger in the conventional art, which is not limited and described herein.
For the air inlet channel 12, it is required to deliver fresh air to different rooms in a room, and because the installation position of the total heat exchanger is fixed and unchanged, and is limited by the positions of different rooms, the lengths of air supply paths from the fresh air delivered by the air inlet channel 12 to different rooms are different. Correspondingly, the wind resistance generated when the fresh air is conveyed to different rooms is different, and in order to meet the requirement of uniform air supply of different rooms, the total heat exchanger is also provided with a shunting adjusting module 2.
Specifically, the diversion adjusting module 2 is provided with a plurality of adjustable air outlets 20; each air outlet 20 is respectively communicated with the air inlet channel 12, each air outlet 20 is used for connecting air outlet equipment in different rooms through an air duct, and the air outlets 20 are used for adjusting air output according to air output requirements.
In the in-service use process, the air output of different air outlets 20 can be adjusted according to the air output requirement of different rooms by the shunting adjusting module 2, and then when the air needs to be uniformly supplied to different rooms, the air output of each air outlet 20 is controlled to be consistent so as to meet the requirement that different rooms all have air supply.
Aiming at the difference of the total air volume of the exchanger main body 1 under different working conditions, the following control is carried out pertinently.
In an embodiment of the present application, when the exchanger body 1 is in the high air output level, the total air output of the air inlet channel 12 and the air outlet channel is relatively large. At this time, when the wind speed of the outlet 20 is greater than the first set wind speed threshold value, the intake volume of the intake channel 12 is reduced in the state that only one outlet 20 is in the wind outlet state.
Specifically, under the high air output gear, the air inlet volume of the air inlet channel 12 is large, if only one air outlet 20 is opened to supply air to a single room, the energy waste is obviously easy to occur, and the air output volume cannot be accurately adjusted. In this case, when the air outlet speed of the air outlet 20 is greater than the first set air speed threshold, the whole air inlet and outlet volume of the exchanger body 1 is reduced, so that the air inlet volume of the air inlet channel 12 is reduced to meet the air outlet requirement of the air outlet 20 in the open state.
Similarly, in the high air output gear, when the air output speed of one of the air outlets 20 is greater than the first set air speed threshold value, the air output area of the air outlet 20 only needs to be reduced when a plurality of air outlets 20 are in the air output state.
Specifically, under the gear with a high air outlet amount, the air inlet channel 12 supplies fresh air to different rooms through different air outlets 20, so as to meet the requirements of the fresh air in different rooms. When the air outlet speed of one of the air outlets 20 is greater than the first set air speed threshold, it indicates that the air output of the air outlet 20 is distributed too much, and in order to meet the requirement of uniform air supply, the air outlet 20 may be adjusted only, that is, the air outlet area of the air outlet 20 is reduced.
In an embodiment of the present application, when the exchanger body 1 is in the medium air output gear, and in a state where N air outlets 20 are in an air output state, when the air output speed of any one air outlet 20 is greater than a first set air speed threshold, the air output areas of the N air outlets 20 are simultaneously reduced; wherein N is not more than 3.
Specifically, taking N =2 as an example, when 2 air outlets 20 are in an air-out state, because the exchanger body 1 is in a medium air-out volume range, the air volume of the air inlet channel 12 is still large as a whole, and at this time, if the air-out speed of one air outlet 20 is greater than the first set air speed threshold, only adjusting the single air outlet 20 will cause the air-out speed of the other air outlet 20 to also exceed the first set air speed threshold. Therefore, when the air outlet speed of any air outlet 20 is greater than the first set air speed threshold, the air outlet areas of the 2 air outlets 20 are simultaneously reduced.
Meanwhile, when the exchanger body 1 is at the medium air output level, and when more than N air outlets 20 are in the air output state, the air output area of each air outlet 20 is adjusted, so that the air output speed of each air outlet 20 is not greater than the first set air speed threshold value.
Specifically, when the air flows out from more than N air outlets 20 simultaneously, and the air flow out of a certain air outlet 20 is greater than the first set air speed threshold, the corresponding air flow adjustment is performed only for the air outlet 20, so that the air flow out of the air outlet 20 is less than the first set air speed threshold, and the requirement of uniform air supply is further met.
In an embodiment of the present application, the total heat exchanger further includes a plurality of wind speed sensors (not shown), the wind speed sensors are configured to detect wind speed of the corresponding compartments, and the wind speed sensors are further configured to trigger the corresponding wind outlets 20 to adjust the wind outlet area.

During actual adjustment, when the wind speed sensor detects that the wind speed of the corresponding compartment is less than the set wind speed value of the user, the corresponding wind outlet 20 is triggered to increase the wind outlet area; otherwise, the corresponding air outlet 20 is triggered to reduce the air outlet area.
In an embodiment of the present application, in order to facilitate the communication between each air outlet 20 and the air inlet channel 12, the shunting adjustment module 2 is further provided with an air box 21, the air box 21 is directly communicated with the air inlet channel 12, the fresh air introduced by the air inlet channel 12 enters the air box 21, the air box 21 is provided with a plurality of air outlets 20, and the fresh air is output from the air box 21 through each air outlet 20.
