The total heat exchange core 18 is arranged inside the casing 21, and the space in the casing 21 is divided into four channels which are communicated with the total heat exchange core 18: fresh air channel, air supply channel, return air channel and exhaust channel.
The fresh air channel is a passage from the fresh air port 11 to one side of the total heat exchange core 18.
The air supply passage is a passage from the side of the total heat exchanging core 18 to the air supply port 4.
The return air passage is a passage from the return air inlet 1 to the side of the total heat exchanging core 18.
The exhaust duct is a passage from the side of the total heat exchange core 18 to the exhaust port 9.
When only the total heat exchanger 100 works, only fresh air is supplied to the indoor space, and the purpose of indoor air quality adjustment is achieved.
When the total heat exchanger 100 is matched with an air conditioner to work, return air from the return air inlet 1 and fresh air from the fresh air inlet 11 are subjected to heat exchange through the total heat exchange core 18.
When the air conditioner operates in a refrigerating period in summer, the fresh air obtains cold energy from return air, so that the temperature is reduced, and meanwhile, the fresh air is dried by the fresh air, so that the humidity of the fresh air is reduced; when the air conditioner operates in a heating period in winter, the fresh air obtains heat from the return air, so that the temperature is raised, and meanwhile, the fresh air is humidified by the return air, so that the humidity of the fresh air is increased.
Referring to fig. 1, the construction of an enthalpy exchanger according to the present application is shown.

When the opening degree of the second controllable valve 12 is increased, the fresh air quantity at the fresh air inlet 11 can be increased; if the opening degree of the second controllable valve 12 is decreased, the fresh air volume at the fresh air port 11 can be decreased.
When the opening degree of the third controllable valve 8 is increased, the air discharge amount at the air discharge port 9 can be increased; if the opening degree of the third controllable valve 8 is decreased, the amount of exhaust air at the exhaust port 9 can be decreased.
The total heat exchanger comprises two modes: an internal circulation mode and a heat exchange mode.
The internal circulation mode and the heat exchange mode of the total heat exchanger can be manually or automatically started according to requirements.
When the internal circulation mode/the heat exchange mode is manually started, the mode can be realized by arranging a knob, the internal circulation mode is started when the knob is rotated to a first position, and the heat exchange mode is started when the knob is rotated to a second position.
When the knob is rotated to a first position, a high level signal is output to the control unit; and when the knob is rotated to a second position, a low level is output to the control unit.
When manually turned on, the control unit receives the position signal of the knob and controls the actions of the first controllable valve 17, the second controllable valve 12, the third controllable valve 8, the exhaust fan 7 and the blower 5 to realize the internal circulation mode or the heat exchange mode.
The control unit (not shown) may be implemented using an ARM integrated chip and its peripheral circuits, which are well known to those skilled in the art.
As in fig. 1, the control unit may be provided in the appliance box 6 in fig. 1.

Internal circulation mode
In the room air CO2When the concentration is lower than the indoor required concentration, if the concentration still carries out the equivalent replacement with the new trend this moment, will cause the energy waste of exhaust fan 7, and also can cause the heat to run off when carrying out the heat transfer with outdoor new trend at indoor cold volume/heat, lead to energy waste, the consumption risees.
For this purpose, the air CO is present in the room2When the concentration is lower than the indoor required concentration, the switch-on inner is selectedAnd (4) circulation mode.

Firstly, the return air from the return air inlet 1 is purified by a second air purification device 19 and then is sent into a fresh air channel;
performing first-layer purification on indoor return air;
secondly, the air flow entering the fresh air channel is purified by the first air purification device and then is sent to the total heat exchange core 18;
carrying out second-layer purification on indoor return air;
thirdly, the air flow after heat exchange is sent into the room from the air supply outlet 4 through the air supply channel under the action of the air supply blower 5.
Under the internal circulation mode, indoor return air is not exchanged with outdoor fresh air, and only the indoor return air is subjected to self circulation, so that the requirement of indoor users on CO is met2On the premise of concentration requirement, energy consumption caused by the work of the exhaust fan 7 is avoided, and meanwhile, heat/cold quantity carried by indoor return air is prevented from losing.
In addition, in the purification cavity 14, the indoor return air is purified in a double layer mode, pollutants in the indoor return air are filtered, the quality of air flow entering the room again is guaranteed, and the situation that the work reliability of the total heat exchange core 18 and the work reliability of the air blower 5 are affected due to the fact that the pollutants in the return air enter the total heat exchange core 18 and the follow-up air blower 5 is avoided.
External circulation mode
In the room air CO2When the concentration is higher than the concentration required in the room, the heat exchange mode is selected to be started.
In the heat exchange mode, the second controllable valve 12, the third controllable valve 8, the exhaust fan 7, and the blower 5 are opened, and the first controllable valve 17 is closed.
The first controllable valve 17 is closed to separate the return air channel from the fresh air channel, so that the return air channel and the fresh air channel are independent of each other.
In the heat exchange mode, the airflow path is explained as follows.
Firstly, the return air from the return air inlet 1 is purified by a second air purification device 19 and then sent into a total heat exchange core body 18 and further enters an exhaust channel;
at this time, the second air cleaning device 19 cleans the indoor return air;
secondly, the air flow entering the air exhaust channel is exhausted out of the room from the air exhaust port 9 under the action of the exhaust fan 7;
outdoor fresh air enters the fresh air channel through the fresh air inlet 11, is purified by the first air purification device, is sent into the total heat exchange core body 18, and then enters the air supply channel;
at the moment, the first air purification device purifies the fresh outdoor air;
and fourthly, the airflow entering the air supply channel is discharged to the indoor from the air supply outlet 4 under the action of the air supply fan 5.
Under the heat exchange mode, indoor return air is exchanged with outdoor fresh air, indoor air circulation is ensured, and indoor air CO is reduced2The concentration improves the indoor air quality, and ensures the user experience.
In addition, the total heat exchanging core 18 is located at the downstream of the second air purifying device 19, and the exhaust fan 7 is located at the downstream of the total heat exchanging core 18, so that the influence of pollutants in indoor return air on the total heat exchanging core 18 and the exhaust fan 7 can be avoided, and the working reliability of the total heat exchanging core 18 and the exhaust fan 7 is ensured.
The total heat exchange core 18 is located at the downstream of the first air purification device, and the blower 5 is located at the downstream of the total heat exchange core 18, so that the influence of pollutants in outdoor fresh air on the total heat exchange core 18 and the blower 5 can be avoided, and the working reliability of the total heat exchange core 18 and the blower 5 is ensured.
