[0029] Figure 1 is a schematic structural diagram of an air treatment system according to an embodiment of the present application, likeFigure 1 As shown, and with reference to Figures 2 to 5 The air treatment system according to the embodiment of the present application comprises an air conditioner 200, an air exchange device 100 and an air conditioner signal acquisition device 300.

[0030] The air exchange device 100 is preferably a total heat exchanger. For example, the air exchange device 100 comprises a shell 121. The shell 121 is provided with a fresh air inlet communicating with the outside, a fresh air outlet communicating with the inside, an exhaust air inlet communicating with the inside and an exhaust air outlet communicating with the outside. The shell 121 is internally provided with a fresh air inlet area 122, an indoor air inlet area 123, an indoor return air area 124 and an outdoor exhaust air area 125, and a total heat exchange core 126. The fresh air inlet area 122 communicates with the fresh air inlet, the indoor air inlet area communicates with the fresh air outlet, and the fresh air inlet area 122 communicates with the indoor air inlet area 123 through the total heat exchange core 126. The indoor return air area 124 communicates with the exhaust air inlet, the outdoor exhaust air area 125 communicates with the exhaust air outlet, and the indoor return air area 124 communicates with the outdoor exhaust air area 125 through the total heat exchange core 126. Further, a fan 127 is arranged in the indoor air inlet area 123 and the outdoor exhaust air area 125, and the fan is preferably a centrifugal fan to facilitate air flow. In some other embodiments, the air exchange device 100 is a fresh air device comprising an air inlet pipe and a fan.

[0031] The air conditioner 200 comprises an indoor unit and an outdoor unit. The indoor unit can be one. Or it is simultaneously provided as multiple to meet the cooling / heating demand of a larger volume of space. In some embodiments, the indoor unit comprises an evaporator for the flow of refrigerant, and the outdoor unit comprises a condenser for the flow of refrigerant. In some other embodiments, the indoor unit comprises a heat exchanger for the flow of water, and the outdoor unit is used to cool or heat the water flow.

[0032] The air conditioner 200 is used for cooling or heating indoors. The air exchange device 100 is used to introduce fresh air into the room, i.e. to exchange air in the room, and to minimize the impact on the temperature in the room.

[0033] In order to synchronize the start and stop of the air exchange device 100 and the air conditioner 200, the air exchange device 100 further comprises a first controller 110, the air conditioner signal acquisition device 300 is configured to acquire the start and / or stop information of the air conditioner 200, and the first controller 110 controls the start and / or stop of the air exchange device 100 according to the start and / or stop information of the air conditioner 200.

[0034] In the embodiment of the present application, when the air conditioner 200 is started or stopped, the air conditioner signal acquisition device 300 acquires or generates the start and / or stop information of the air conditioner 200, and the first controller 110 obtains the start and / or stop information, and then controls the air exchange device 100 to start or stop. This arrangement makes the air conditioner 200 and the air exchange device 100 form an organic whole linkage system.

[0035] That is, the linkage system of the air conditioner 200 and the ventilation device 100 has the air conditioner signal acquisition device 300, so that the ventilation device 100 obtains the start and stop information of the air conditioner 200 by using the air conditioner signal acquisition device 300, and then controls the ventilation device 100 and the air conditioner 200 to start and stop in linkage. In this way, it can be prevented that the equipment manager only turns on the air conditioner 200 and forgets to turn on the ventilation device 100, or only turns off the air conditioner 200 and forgets to turn off the ventilation device 100, and further prevents waste of electricity and energy saving. The equipment manager is also relatively simple to operate. A centralized controller does not need to be added for the two systems, and signal lines, power lines and other cables do not need to be laid, thereby reducing the cost.

[0036] In some embodiments of the utility model, as shown in Figures 2 to 4 The air conditioner 200 further comprises a second controller 210, and the air conditioner signal acquisition device 300 is arranged between the first controller 110 and the second controller 210. The air conditioner signal acquisition device 300 is directly arranged between the two controllers, facilitating the arrangement of the air conditioner signal acquisition device 300 and having a simple structure. For example, the first controller and the second controller are electrically connected with the signal acquisition device; the signal acquisition device is used to transmit signals between the first controller and the second controller, or the signal acquisition device is used to generate signals provided to the second controller when the first controller acts.

[0037] In some embodiments of the utility model, the first controller 110 and the second controller 210 are arranged adjacent to each other, and the air conditioner signal acquisition device 300 is an electric connection line connecting the first controller 110 and the second controller 210. The electric connection line can be used to acquire signals or generate signals.

[0038] In some embodiments of the utility model, as shown in Figure 3 The first controller 110 is a drive-by-wire controller, and the second controller 210 is a drive-by-wire controller. The drive-by-wire controller is usually arranged on a wall, and the two drive-by-wire controllers are usually arranged adjacent to each other and connected together by the electric connection line, which has a simple structure, low cost, and is also convenient for the synchronous start and stop of the air conditioner 200 and the ventilation device 100.

[0039] In some embodiments of the utility model, the air conditioner signal acquisition device is a dry contact signal line. Further, the first controller 110 comprises a control switch used to control the start and / or stop, and the electric connection line is connected to the control switch. When the air conditioner 200 starts, the control switch is turned on, and then a current is generated on the dry contact signal line, which is the start signal of the air conditioner 200. When the air conditioner 200 stops, the control switch is turned off, and then the current on the dry contact signal line is lost, which is the stop signal of the air conditioner 200.

[0040] In the embodiment of the utility model, since the electric connection line is a dry contact signal line, and since the dry contact is passive, the dry contact signal line does not need an additional power supply when transmitting signals. This makes the dry contact signal line more simple and convenient when connecting two controllers, and also reduces the complexity and cost of the system, and realizes accurate transmission and processing of signals.

[0041] In some embodiments of the utility model, the first controller 110 is connected with an input module to receive input information for controlling the power-on and / or power-off of the ventilation device 100, and the first controller 110 is further configured to control according to the information of the input module. That is, the ventilation device 100 has two working modes, namely a first mode and a second mode, and the first mode can also be referred to as a linkage mode, and the second mode can also be referred to as a default mode. In the first mode, the first controller 110 controls according to the information of the air conditioner signal acquisition device 300; in the second mode, the first controller 110 controls according to the information of the input module. By setting multiple modes, the diversification of the control of the ventilation device 100 is improved.

[0042] In some optional embodiments, the ventilation device 100 controls according to the information of the air conditioner signal acquisition device 300, and during this period, when the user operates the input module, i.e. touches the switch button, the ventilation device 100 controls according to the information of the input module. For example, if the air conditioner is in an off state at this time, the input information of the input module is power-on information, then the ventilation device 100 is powered on, without waiting for the information of the air conditioner signal acquisition device 300. If the air conditioner is powered on thereafter, the ventilation device remains powered on without action. If the air conditioner is powered off, the ventilation device 100 is powered off according to the information of the air conditioner signal acquisition device 300. If the ventilation device 100 is powered on and off according to the input information of the input module, and if the air conditioner is not powered on during this period, then after the air conditioner is powered on, if the ventilation device 100 is not powered on, the ventilation device 100 is powered on according to the information of the air conditioner signal acquisition device 300. If the air conditioner and the ventilation device 100 are both in a powered-on state, the input information of the input module is power-off information, then the ventilation device 100 is powered off, without waiting for the information of the air conditioner signal acquisition device 300. Until the air conditioner is powered on again, and then the ventilation device 100 is powered on according to the information of the air conditioner signal acquisition device 300. That is, the ventilation device 100 is controlled according to the information of the air conditioner signal acquisition device 300, but when the input module is operated, the information of the input module is executed. That is, based on the input module, the ventilation device 100 can be powered on and off before the air conditioner 200; when the air conditioner is not working, the ventilation device can be powered on and off independently; during the working period of the air conditioner, the ventilation device can be powered off and then powered on, etc.

[0043] In some embodiments of the utility model, the first controller 110 is connected with a mode selection module to perform the action of the first mode or the action of the second mode according to the information of the mode selection module. In the embodiments of the utility model, the mode of the drive-by-wire controller of the ventilation device 100 can be set as a linkage mode or a default mode. The user can select the working mode of the ventilation device 100 through the mode selection module. In the default mode, the drive-by-wire controller of the ventilation device 100 is touched to control the start or stop of the ventilation device 100 manually. In the linkage mode, the ventilation device 100 is automatically controlled according to the linkage signal. If the air conditioner 200 is started, the ventilation device 100 receives the linkage signal of the start of the air conditioner 200, and the ventilation device 100 is automatically started in linkage; if the air conditioner 200 is stopped, the ventilation device 100 receives the linkage signal of the stop of the air conditioner 200, and the ventilation device 100 is automatically stopped in linkage.

[0044] In some other embodiments of the utility model, as shown in Figure 4 The air conditioner signal acquisition device 300 is a wireless transmission device, and the wireless transmission device includes a first wireless module 320 arranged on the air conditioner 200 and a second wireless module 310 arranged on the ventilation device 100. For example, wireless modules are arranged on the two drive-by-wire controllers, and the line connection between the two controllers is omitted through the arrangement of the wireless modules, and the connection is more convenient. Specifically, the first wireless module 320 and the second wireless module 310 are both Bluetooth modules or wifi modules.

[0045] Preferably, the first wireless module 320 and the second wireless module 310 are both Bluetooth modules. After the air conditioner 200 is started, the first wireless module 320 is started, the second wireless module 310 is automatically paired with the first wireless module 320, and after the pairing is successful, it is recognized that the air conditioner 200 is started, and the ventilation device 100 is automatically started. After the air conditioner 200 is stopped, the first wireless module 320 stops working, and the second wireless module 310 loses pairing, so it is recognized that the air conditioner 200 is stopped, and the ventilation device 100 is automatically stopped, realizing the linkage of the air conditioner 200 and the ventilation device 100.

[0046] In some embodiments of the utility model, the fresh air outlet and the exhaust air inlet are both provided with air guide devices. The air guide device is provided with a plurality of air guide plates arranged in sequence in the up-down direction and rotatable. The upper end of the air guide plate is rotatably installed on the shell 121 and is blocked against the corresponding fresh air outlet and exhaust air inlet by its own gravity or the force of a torsional spring. The air guide plate is configured to rotate under the driving of the airflow through the corresponding fresh air outlet and exhaust air inlet to open the corresponding fresh air outlet and exhaust air inlet. When fresh air needs to be replaced, both centrifugal fans are started to generate airflow, which drives the air guide plate to move and open the corresponding fresh air outlet and exhaust air inlet and adjust the ventilation size. Generally, the greater the airflow, the greater the angle of the air guide plate away from the initial position. Therefore, the angle of the air guide plate can be adjusted by adjusting the size of the airflow. When the airflow stops, the air guide plate can return to the initial position under the action of gravity or the torsional spring.

[0047] In some embodiments of the utility model, as shown in Figure 5 The indoor air inlet area 123 and the outdoor exhaust air area 125 are located on one side of the shell 121, and the fresh air inlet area 122 and the full-heat heat exchange core 126 and the indoor return air area 124 are located on the other side of the shell 121, so that the parts in the shell 121 are arranged compactly and reasonably, and the staff can install conveniently.

[0048] In some embodiments of the utility model, as shown in Figure 5 The shell 121 is further provided with a first air guide channel 128, the first air guide channel 128 is provided with a first air door 129, one end of the first air guide channel 128 is communicated with the indoor air inlet area 123, and the other end is communicated with the fresh air inlet area 122. When the indoor and outdoor temperature difference is small, the first air door 129 can be opened, a part of fresh air does not pass through the heat exchanger and directly enters the indoor air inlet area 123, the fresh air replacement efficiency is greatly improved, the indoor comfort is increased, and the service life of the heat exchange core is increased. When the indoor and outdoor temperature difference is large, the first air door 129 can be closed. When the indoor and outdoor temperature difference is large, the first air door 129 can also be opened when the temperature difference is not considered and only the fresh air replacement efficiency is considered.

[0049] In some embodiments of the utility model, the shell 121 is further provided with a second air guide channel, the second air guide channel is provided with a second air door, one end of the second air guide channel is communicated with the indoor return air area 124, and the other end is communicated with the outdoor exhaust air area 125. When the indoor and outdoor temperature difference is small, the second air door can be opened. When the indoor and outdoor temperature difference is large, the second air door can be closed. When the indoor and outdoor temperature difference is large, the second air door can also be opened when the temperature difference is not considered and only the fresh air replacement efficiency is considered. Optionally, in order to ensure that the cold or heat of the indoor exhaust air is fully utilized, the second air door can be always in the closed state. The second air guide channel is arranged on the lower side of the first air guide channel 128, so that the structure layout is more reasonable and compact.
