FIG. 1 is a block schematic diagram of a new fan system according to one embodiment of the present invention. As shown in fig. 1, the new fan system includes: a fresh air module 10, an indoor return air module 20, an air supply module 30 and a control module (not specifically shown in the figure).
The fresh air module 10 includes a temperature detection unit 101, a first fan 102 and a first heating unit 103, the temperature detection unit 101 is used for detecting the outdoor environment temperature T, the first fan 102 is used for conveying outdoor inlet air, and the first heating unit 103 is used for heating the outdoor inlet air. The indoor return air module 20 includes a second fan 201 and a second heating unit 202, the second fan 201 is used for conveying the indoor return air, and the second heating unit 202 is used for heating the indoor return air. The air supply module 30 is respectively connected with the fresh air module 10 and the indoor return air module 20, the air supply module 30 comprises a third fan 301 and an infrared detection unit 302, the third fan 301 is used for sending mixed outdoor air inlet and indoor return air into a room, and the infrared detection unit 302 is used for detecting whether people are in the room to generate personnel detection information. The control module is used for controlling the first fan 102 to be started after receiving the starting instruction, judging whether to control the second fan 201 and the third fan 301 to be started or not according to the outdoor environment temperature T, controlling the operation wind gear of the second fan 201 and the third fan 301 according to the outdoor environment temperature T and the personnel detection information after the second fan 201 and the third fan 301 are started, and controlling the on-off of the first heating unit 103 and the second heating unit 202.
Further, in the embodiment of the present invention, during the operation of the new fan system, the control module is configured to control the first fan 102 to operate in the first wind gear.
Specifically, the temperature detection unit 101 may be a temperature sensor, and may be disposed on an air inlet side of the new air blower system. The infrared detection unit 302 may be an infrared detector, and may be disposed on the air outlet side of the new fan system. After receiving the start-up instruction, the control module controls the first fan 102 to start and operate in a first wind gear, and then determines whether the second fan 201 and the third fan 301 need to be started according to the outdoor environment temperature T detected by the temperature detection unit 101, for example, in spring and summer, the outdoor environment temperature is high, and the second fan 201 and the third fan 301 do not need to be controlled to start; in autumn and winter, the outdoor environment temperature T is low, the control module can control the second fan 201 and the third fan 301 to be started, and because the indoor environment temperature is generally higher than the outdoor environment temperature T in autumn and winter, the temperature of the mixed air conveyed to the air supply module 30 can be increased by simultaneously starting the first fan 102 and the second fan 201, so that the indoor environment temperature is maintained within a certain range, and the comfort of a user is improved. After the second fan 201 and the third fan 301 are controlled to be started, the control module controls the operating wind shelves of the second fan 201 and the third fan 301 according to the outdoor environment temperature T and the detection information of the personnel detected by the infrared detection unit 302, and controls the switches of the first heating unit 103 and the second heating unit 202, for example, if no person is in the room and the indoor environment temperature is not very low, the first heating unit 103 and the second heating unit 202 are controlled to be closed, so as to save electric energy; if people are in the room and the indoor environment temperature is low, the first heating unit 103 can be controlled to be turned on by the second heating unit 202 to heat the wind sent into the room, so that the indoor environment temperature is maintained within a certain range, and the comfort of the user is improved. Therefore, the system carries out switch control on each fan and each heating unit by integrating outdoor environment temperature conditions and indoor personnel conditions, adjusts the wind gear of each fan, can ensure the air supply temperature so as to ensure the comfort of users, and can effectively reduce energy consumption.
In an embodiment of the present invention, as shown in fig. 1, the air supply module 30 may further include a haze removal filtering unit 303, which is configured to perform haze removal, filtering and the like on the outdoor intake air or the mixed air of the outdoor intake air and the indoor return air to purify the indoor air. The first heating unit 103 and the second heating unit 202 may be PTC (Positive Temperature Coefficient, broadly referred to as semiconductor material or component having a large Positive Temperature Coefficient) heaters.
According to an embodiment of the present invention, the control module is further configured to determine whether the outdoor environment temperature T is greater than or equal to a first preset temperature T1; if the outdoor environment temperature T is greater than or equal to the first preset temperature T1, controlling the second fan 201, the third fan 301, the first heating unit 103 and the second heating unit 202 to be in the off state; and if the outdoor environment temperature T is less than the first preset temperature T1, controlling the second fan 201 and the third fan 301 to be respectively turned on.
Specifically, the first preset temperature T1 may be preset according to actual conditions, and may be 15 ℃. When the control module receives a starting instruction, the first fan 102 is controlled to be started and operate at a first wind gear, then the outdoor environment temperature T is obtained, whether the outdoor environment temperature T is larger than or equal to 15 ℃ or not is judged, if the outdoor environment temperature T is larger than or equal to 15 ℃, the outdoor environment temperature T is not very low, outdoor inlet air does not need to be heated, and the second fan 201, the third fan 301, the first heating unit 103 and the second heating unit 202 are controlled to be in a closed state. And if T < 15 ℃, the outdoor environment temperature T is lower, and if outdoor inlet air is directly introduced into a room, the indoor environment temperature is reduced, and the comfort of a user is influenced. When the outdoor environment temperature T is low, the indoor environment temperature is generally higher than the outdoor environment temperature T, and therefore, the control module can control the second fan 201 and the third fan 301 to be respectively started, outdoor air inlet conveyed by the first fan 102 and indoor return air conveyed by the second fan 201 are mixed and then conveyed to the third fan 301, and then the mixture is conveyed indoors through the third fan 301, so that the temperature of the indoor air conveyed into the room can be increased, and the comfort of a user is ensured.
Further, according to an embodiment of the present invention, after the second fan 201 and the third fan 301 are turned on, the control module is further configured to determine whether there is a person in the room according to the person detection information, and control the second fan 201 to operate at the first wind level and the third fan 301 to operate at the second wind level when there is no person in the room, and determine whether the outdoor environment temperature T is greater than or equal to a second preset temperature T2, wherein if the outdoor environment temperature T is greater than or equal to the second preset temperature T2, the second fan 201 is controlled to maintain the first wind level operation and the third fan 301 is controlled to maintain the second wind level operation, and the first heating unit 102 and the second heating unit 202 are both controlled to be in an off state; and if the outdoor environment temperature T is less than a second preset temperature T2, controlling the second fan 201 to keep the first fan operating and controlling the third fan 301 to keep the second fan operating, and controlling the first heating unit 103 to be in a closed state and the second heating unit 202 to be turned on, wherein the second preset temperature T2 is less than the first preset temperature T1.
In particular, the second preset temperature T2 may be preset according to the actual situation, for example 0 ℃. After the second fan 201 and the third fan 301 are started, the control module judges whether a person is in a room according to the information of the person detected by the infrared detection unit 302, if no person is in the room, the control module controls the second fan 201 to operate in a first wind gear and controls the third fan 301 to operate in a second wind gear, and judges whether T is more than or equal to 0 ℃ and less than 15 ℃ or not, if T is more than or equal to 0 ℃ and less than 15 ℃, because no person is in the room and the outdoor environment temperature T is not particularly low, the first heating unit 102 and the second heating unit 202 are controlled to be in a closed state, and electric energy is saved. If T is less than 0 ℃, the outdoor ambient temperature T is too low, so as to prevent the indoor temperature from being reduced too much due to the introduction of outdoor air when people come indoors suddenly, and therefore, the control module controls the first heating unit 103 to be in the off state and controls the second heating unit 202 to be turned on, so as to heat the indoor return air. Because the indoor ambient temperature is generally higher than the outdoor ambient temperature T, the same power is consumed, the temperature of the outdoor inlet air and the indoor return air mixed after the indoor return air is heated by the second heating unit 202 is controlled to be higher than the temperature of the outdoor inlet air and the indoor return air mixed after the outdoor inlet air is heated by the first heating unit 103, and therefore the comfort of a user can be remarkably improved by controlling the second heating unit 202 to be started.
Further, according to an embodiment of the present invention, when there is a person in the room, the control module is further configured to control the second fan 201 to operate in the first wind range and control the third fan 301 to operate in the second wind range, and determine whether the outdoor environment temperature T is greater than or equal to a second preset temperature T2, wherein if the outdoor environment temperature T is greater than or equal to the second preset temperature T2, the control module controls the second fan 201 to operate in the second wind range and controls the third fan 301 to operate in the third wind range, and controls both the first heating unit 103 and the second heating unit 202 to be in the off state.
When the outdoor environment temperature T is less than the second preset temperature T2, the control module is further configured to detect a distance S between the air supply outlet of the air supply module 30 and a person through the infrared detection unit 302, and determine whether the distance S is less than a preset distance S1, wherein if the distance S is less than the preset distance S1, the control module controls the second fan 201 to operate in a second wind range and controls the third fan 301 to operate in a third wind range, and controls the first heating unit 103 to be in a closed state and controls the second heating unit 202 to be turned on; and if the distance S is greater than or equal to the preset distance S1, controlling the second fan 201 to operate in the second wind range and the third fan 301 to operate in the third wind range, and controlling the first heating unit 103 to be turned on and the second heating unit 201 to be in a turned-off state. The preset distance S1 may be preset according to actual conditions, and may be 3m, for example.
Specifically, when the control module determines that a person is present in the room according to the information of the person detected by the infrared detection unit 302, the control module controls the second fan 201 to operate in the first wind range and controls the third fan 301 to operate in the second wind range, and determines whether T is greater than or equal to 0 ℃ and less than 15 ℃, and if T is greater than or equal to 0 ℃ and less than 15 ℃, it indicates that the outdoor environment temperature T is not particularly low, so that the control module can control the first heating unit 102 and the second heating unit 202 to be in the off state, so as to save electric energy.
Because the sensitivity of the human body to the fresh air conveyed by the air supply opening is related to the distance S between the air supply opening and the human body, the larger the distance S between the air supply opening and the human body is, the lower the sensitivity of the human body is. Therefore, when T is less than 0 ℃, the control module detects the distance S between the air supply outlet of the air supply module 30 and a person through the infrared detection unit 302, and determines whether S is less than 3m, if S is less than 3m, the sensitivity of a human body to fresh air conveyed by the air supply outlet is high, and the outdoor environment temperature T is too low, so that the control module controls the second fan 201 to operate at the second wind level and controls the third fan 301 to operate at the third wind level, and controls the first heating unit 103 to be in the closed state, and the second heating unit 202 to be turned on, so as to heat indoor return air. Because the indoor ambient temperature is generally higher than the outdoor ambient temperature T, the same power is consumed, the temperature of the outdoor inlet air and the indoor return air mixed after the indoor return air is heated by the second heating unit 202 is controlled to be higher than the temperature of the outdoor inlet air and the indoor return air mixed after the outdoor inlet air is heated by the first heating unit 103, and therefore the comfort of a user can be remarkably improved by controlling the second heating unit 202 to be started. And if S is larger than or equal to 3m, the sensitivity of the human body to the fresh air conveyed by the air supply outlet is low, so that the control module can control the second fan 201 to operate at a second wind level and the third fan 301 to operate at a third wind level, and control the first heating unit 103 to be started and control the second heating unit 201 to be in a closed state.
It can be understood that the air quantity of the first gear is less than that of the second gear and less than that of the third gear.
In order to make the present invention more clearly understood by those skilled in the art, the control logic of the control module of the new fan system is described below with reference to table 1.1 and table 1.2.

And S20, judging whether to control the second fan and the third fan to be started or not according to the outdoor environment temperature T.
And S30, after the second fan and the third fan are started, controlling the running wind gears of the second fan and the third fan according to the outdoor environment temperature T and the personnel detection information, and controlling the opening and closing of the first heating unit and the second heating unit according to the outdoor environment temperature T and the personnel detection information.
Specifically, the outdoor ambient temperature T can be detected by arranging a temperature sensor on the air intake side of the fresh air fan system. The infrared detection unit can be arranged on the air outlet side of the fresh air fan system. After a starting instruction is received, the first fan is controlled to be started and operates at a first wind gear, and whether the second fan and the third fan need to be started is judged according to the outdoor environment temperature T, for example, in spring and summer, the outdoor environment temperature is high, and the second fan and the third fan do not need to be controlled to be started; in autumn and winter, the outdoor environment temperature T is lower, the second fan and the third fan can be controlled to be started, and because the general indoor environment temperature in autumn and winter is higher than the outdoor environment temperature T, the temperature of the mixed air conveyed to the air supply module can be improved by simultaneously starting the first fan and the second fan, so that the indoor environment temperature is maintained in a certain range, and the comfort of a user is improved. After the second fan and the third fan are controlled to be started, the operating dampers of the second fan and the third fan are controlled according to the outdoor environment temperature T and detection information of personnel detected by the infrared detection unit, and the switches of the first heating unit and the second heating unit are controlled, for example, if no person exists indoors and the indoor environment temperature is not very low, the first heating unit and the second heating unit are controlled to be closed, so that the electric energy is saved; and if someone is in the room and the indoor ambient temperature is lower, then can control first heating unit and get the second heating unit and open to heat the wind of sending into indoor, make indoor ambient temperature maintain in certain extent, improve user's travelling comfort. Therefore, the method carries out switch control on each fan and each heating unit by integrating the outdoor environment temperature condition and the indoor personnel condition, and adjusts the fan wind shield, thereby not only ensuring the air supply temperature and the comfort of users, but also effectively reducing the energy consumption.
According to an embodiment of the present invention, after the first fan is turned on, it is determined whether the outdoor environment temperature is greater than or equal to a first preset temperature T1, wherein if the outdoor environment temperature T is greater than or equal to the first preset temperature T1, the second fan, the third fan, and the first heating unit and the second heating unit are all controlled to be in an off state; and if the outdoor environment temperature T is less than the first preset temperature T1, controlling the second fan and the third fan to be respectively started.
Specifically, the first preset temperature T1 may be preset according to actual conditions, and may be 15 ℃. And after a starting instruction is received, controlling the first fan to be started and operate at a first wind gear, then obtaining the outdoor environment temperature T and judging whether the outdoor environment temperature T is more than or equal to 15 ℃, if the outdoor environment temperature T is more than or equal to 15 ℃, indicating that the outdoor environment temperature T is not very low, heating outdoor inlet air is not needed, and controlling the second fan, the third fan, the first heating unit and the second heating unit to be in a closed state. And if T < 15 ℃, the outdoor environment temperature T is lower, and if outdoor inlet air is directly introduced into a room, the indoor environment temperature is reduced, and the comfort of a user is influenced. When the outdoor environment temperature T is lower, the indoor environment temperature is generally higher than the outdoor environment temperature T, therefore, the second fan and the third fan can be controlled to be respectively started, outdoor air inlet conveyed by the first fan and indoor return air conveyed by the second fan are mixed and then conveyed to the third fan, and then the mixture is conveyed into a room through the third fan, so that the temperature of the air fed into the room can be improved, and the comfort of a user is ensured.

In particular, the second preset temperature T2 may be preset according to the actual situation, for example 0 ℃. After the second fan and the third fan are started, whether a person is in a room or not can be judged according to the information of the person detected by the infrared detection unit, if no person is in the room, the second fan is controlled to operate in a first wind gear and the third fan is controlled to operate in a second wind gear, whether T is more than or equal to 0 ℃ and less than 15 ℃ or not is judged, and if T is more than or equal to 0 ℃ and less than 15 ℃, because no person is in the room and the outdoor environment temperature T is not particularly low, the first heating unit and the second heating unit are controlled to be in a closed state, so that electric energy is saved. If T is less than 0 ℃, because the outdoor environment temperature T is too low, the indoor temperature is reduced too much due to the introduction of outdoor air when people come indoors suddenly, and therefore the first heating unit can be controlled to be in a closed state and the second heating unit can be controlled to be started to heat the indoor return air. Because the indoor ambient temperature is generally higher than the outdoor ambient temperature T, therefore, consume the same power, the temperature of the outdoor air inlet and the indoor return air that mix after the control second heating unit heats the indoor return air is higher than the outdoor air inlet and the indoor return air that mix after the first heating unit heats the outdoor air inlet, consequently the control second heating unit opens and to show improvement user's travelling comfort.
Further, according to an embodiment of the present invention, when a person is present in the room, the second fan is controlled to operate at the first wind level and the third fan is controlled to operate at the second wind level, and it is determined whether the outdoor ambient temperature T is greater than or equal to a second preset temperature T2, wherein if the outdoor ambient temperature T is greater than or equal to the second preset temperature T2, the second fan is controlled to operate at the second wind level and the third fan is controlled to operate at the third wind level, and both the first heating unit and the second heating unit are controlled to be in the off state.
When the outdoor environment temperature T is less than a second preset temperature T2, detecting the distance S between the air supply outlet of the air supply module and a person through the infrared detection unit, and judging whether the distance S is less than a preset distance S1, wherein if the distance S is less than a preset distance S1, the second fan is controlled to operate at a second wind shield, the third fan is controlled to operate at a third wind shield, and the first heating unit is controlled to be in a closed state and the second heating unit is controlled to be started; and if the distance S is greater than or equal to the preset distance S1, controlling the second fan to operate in a second wind gear, controlling the third fan to operate in a third wind gear, and controlling the first heating unit to be switched on and controlling the second heating unit to be in a switched-off state. The preset distance S1 may be preset according to actual conditions, and may be 3m, for example.
Specifically, when the person is judged to be in a room according to the information of the person detected by the infrared detection unit, the second fan can be controlled to operate at the first wind level and the third fan can be controlled to operate at the second wind level, whether T is more than or equal to 0 ℃ and less than 15 ℃ is judged, and if T is more than or equal to 0 ℃ and less than 15 ℃, the outdoor environment temperature T is not particularly low, so that the first heating unit and the second heating unit can be controlled to be in a closed state, and the electric energy is saved.
