Description

Technical Field

[0002] With the increasing requirements for indoor air quality, air-conditioning products with integrated fresh air function, namely fresh air air-conditioners, have emerged. The existing fresh air air-conditioners are provided with a fresh air device for delivering fresh air to the indoor room and an exhaust device for exhausting the indoor air to the outdoors. By cooperating with the fresh air device, the indoor air that has undergone heat exchange with the air-conditioner can be mixed with the outdoor fresh air and then blown into the indoor room. This can avoid the outdoor fresh air from having a greater impact on the local indoor temperature. Although this method can mix the introduced humid hot air or dry cold air with the air blown out after the air conditioner itself has exchanged heat with the indoor air to achieve indoor temperature regulation, when the fresh air air-conditioner introduces outdoor air into the room, the difference in indoor and outdoor air humidity will cause an imbalance in the indoor air humidity, making it difficult for the fresh air air-conditioner to control the humidity while controlling the temperature, affecting the comfort of the fresh air air-conditioner.

[0042] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0043] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0044] The specific embodiment of the present invention provides an air volume control mechanism, combined with the following Figure 1 ~Attached Figure 7 As shown, it includes at least one wind shield structure 1, which is respectively arranged at the air outlet 7 of the fresh air device 4 and the air inlet 8 of the exhaust device 5. The wind shield structure 1 can change the ventilation volume of the air outlet 7 of the fresh air device 4 and the ventilation volume of the air inlet 8 of the exhaust device 5. In this way, by adjusting the ventilation volume of the air outlet 7 of the fresh air device 4 and the ventilation volume of the air inlet 8 of the exhaust device 5, the indoor air humidity is indirectly controlled to avoid excessive changes in indoor air humidity due to the difference in indoor and outdoor humidity, thereby affecting the comfort of the fresh air air conditioner.

[0045] There can be two wind shield structures 1, which are respectively arranged in the air outlet 7 of the fresh air device 4 and the air inlet 8 of the exhaust device 5. The two wind shield structures 1 can independently control the air outlet volume of the fresh air device 4 and the air inlet volume of the exhaust device 5, and can be bidirectionally controlled by separately controlling the two wind shield structures 1.

[0046] The windshield structure 1 provided in the specific embodiment of the present application includes a driving part 2 and a windshield part 3 connected to the driving part 2. The driving part 2 is a component that provides driving force, and a motor, such as a stepping motor, can be used. The windshield part 3 is a structure that can cover the air outlet 7 of the fresh air device 4 and the air inlet 8 of the exhaust device 5, and can open the air outlet 7 and the air inlet 8. For example, the windshield part 3 can be a windshield plate, which can completely cover the air outlet 7 of the fresh air device 4 and the air inlet 8 of the exhaust device 5, and the windshield plate is connected to the output shaft of the motor.

[0047] The windshield plate arranged in the air outlet 7 of the fresh air device 4 can swing within the range of 0° to 70° with the end face of the air outlet 7 of the fresh air device 4, and the windshield plate in the air inlet 8 of the exhaust device 5 can swing within the range of 0° to 70° with the end face of the air inlet 8 of the exhaust device 5. The windshield plate is driven to swing by a motor. When the angle of the windshield plate is 0°, as shown in the attached figure, Figure 3 and attached Figure 5 As shown, the wind shield completely covers the air outlet 7 of the fresh air device 4 or the air inlet 8 of the exhaust device 5; when the wind shield angle is 70°, as shown in the attached Figure 2 and attached Figure 4 As shown, this is the maximum opening angle of the wind shield, at which the air blowing volume of the fresh air device 4 or the air intake volume of the exhaust device 5 is the largest.

[0048] The specific embodiment of the present application also provides a fresh air air conditioner, including a body 6, a fresh air device 4, an exhaust device 5 and the above-mentioned air volume control mechanism, the fresh air device 4 and the exhaust device 5 are both arranged on the body 6, and as shown in the attached Figure 1 As shown, the fresh air device 4 and the exhaust device 5 are respectively arranged at two ends of the machine body 6 to avoid mutual influence between the fresh air device 4 and the exhaust device 5.

[0049] The air outlet 7 of the fresh air device 4 is arranged at one end of the body 6, and the air inlet 8 is arranged on the other end of the body 6 away from the air outlet 7. The two air outlets are arranged at a relatively far distance from each other to avoid the problem that the fresh air blown by the fresh air device 4 is easily discharged outdoors by the exhaust device 5, causing energy waste and low efficiency of the fresh air air conditioner in blowing fresh air. The air inlet position of the air inlet 8 and the air outlet position of the air outlet 7 can also be kept away from each other by arranging an air duct at the air inlet 8 of the exhaust device 5 and / or the air outlet 7 of the fresh air device 4. In this way, the problem of mutual influence between the air outlet 7 and the air inlet 8 can be avoided.

[0050] The present application also provides an air-conditioning system, comprising the above-mentioned fresh air air-conditioning.

[0051] The specific embodiment of the present application also provides a humidity control method, Fig. 9 As shown, the following steps are included:

[0052] Step S101, obtaining indoor air humidity information;

[0053] When the fresh air air conditioner introduces outdoor air into the room, the difference in indoor and outdoor air humidity will cause an imbalance in the indoor air humidity. To address the above problem, the present application obtains indoor air humidity information. The indoor air humidity information can be obtained in real time or at preset time intervals, for example, every few seconds.

[0054] Step S102: If the indoor air humidity is lower than a preset first humidity value, and the ratio of the ventilation volume at the current fresh air device outlet to the ventilation volume at the exhaust device inlet is lower than a preset first threshold, increase the ventilation volume at the fresh air device outlet and / or reduce the ventilation volume at the exhaust device inlet.

[0055] When it is determined that the indoor air humidity is less than the preset first humidity value, and the ratio of the calculated ventilation volume at the current fresh air device outlet to the ventilation volume at the exhaust device inlet is less than the preset first threshold value, it indicates that the indoor air humidity is lower than the preset first humidity value and needs to be adjusted. For this purpose, the adjustment method may be to increase the ventilation volume at the fresh air device outlet and keep the ventilation volume at the exhaust device inlet unchanged; the ventilation volume at the fresh air device outlet may be unchanged and the ventilation volume at the exhaust device inlet may be reduced; or the ventilation volume at the fresh air device outlet may be increased and the ventilation volume at the exhaust device inlet may be reduced. The method of increasing the ventilation volume at the fresh air device outlet is aimed at introducing more outdoor humid air into the room to increase the indoor air humidity; the method of reducing the ventilation volume at the exhaust device inlet is aimed at reducing the discharge of indoor air through the exhaust device, aiming at preventing the indoor air from carrying moisture and reducing the indoor air humidity; by controlling the ventilation volume, adjusting the mixing ratio of indoor air and outdoor air, and then increasing the indoor air humidity, so that the fresh air air conditioner can achieve humidity control.

[0056] In one embodiment, when judging the indoor air humidity information, if the indoor air humidity is greater than a preset second humidity value, and the ratio of the ventilation volume of the current fresh air device outlet to the ventilation volume of the exhaust device inlet is greater than a preset second threshold value, the ventilation volume of the fresh air device outlet is reduced, and / or the ventilation volume of the exhaust device inlet is increased.

[0057] Specifically, if the indoor air humidity is greater than the preset second humidity value, and the ratio of the ventilation volume of the current fresh air device outlet to the ventilation volume of the exhaust device inlet is greater than the preset second threshold value, the indoor air humidity is relatively large and in an unbalanced state, and needs to be adjusted. For this reason, the adjustment method in this embodiment can be to reduce the ventilation volume of the fresh air device outlet and keep the ventilation volume of the exhaust device inlet unchanged; it can be to keep the ventilation volume of the fresh air device outlet and increase the ventilation volume of the exhaust device inlet; it can also be to reduce the ventilation volume of the fresh air device outlet and increase the ventilation volume of the exhaust device inlet. All three methods can reduce the indoor air humidity; among them, reducing the ventilation volume of the fresh air device outlet can effectively reduce the outdoor humid air from entering the room, avoiding further increasing the indoor air humidity; increasing the ventilation volume of the exhaust device inlet can effectively increase the discharge of indoor humid air, thereby reducing the indoor air humidity.

[0058] In one embodiment, after increasing the ventilation volume of the air outlet of the fresh air device and / or reducing the ventilation volume of the air inlet of the exhaust device; if the indoor air humidity is still lower than the preset first humidity value; the ventilation volume of the air outlet of the fresh air device is increased again, and / or the ventilation volume of the air inlet of the exhaust device is reduced.

[0059] Specifically, such adjustment can further increase the ventilation volume of the air outlet of the fresh air device, thereby increasing the amount of outdoor humid air introduced into the room per unit time; it can also further reduce the amount of indoor air discharged through the exhaust device, thereby reducing the amount of indoor air discharged per unit time, and ultimately accelerating the increase of indoor air humidity, which is conducive to the indoor air humidity quickly entering the comfortable humidity range; this embodiment may perform multiple adjustments in the above manner in actual control because the indoor air humidity is less than the preset first humidity value and the ratio of the ventilation volume of the air outlet of the fresh air device to the ventilation volume of the air inlet of the exhaust device is less than the preset first threshold value.

[0060] In one embodiment, after reducing the ventilation volume of the air outlet of the fresh air device and / or increasing the ventilation volume of the air inlet of the exhaust device; if the indoor humidity is still greater than a preset second humidity value; the ventilation volume of the air outlet of the fresh air device is reduced again, and / or the ventilation volume of the air inlet of the exhaust device is increased.

[0061] Specifically, the ventilation volume of the air outlet of the fresh air device is reduced again on the basis of the last reduction in the ventilation volume of the air outlet of the fresh air device, thereby further reducing the amount of outdoor humid air introduced into the room per unit time; the ventilation volume of the air inlet of the exhaust device is increased again on the basis of the last increase in the ventilation volume of the air inlet of the exhaust device, thereby further increasing the amount of indoor air discharged from the outdoors per unit time; such further adjustment further accelerates the speed of reducing the indoor air humidity, which is conducive to the indoor air humidity quickly entering the comfortable humidity range; in actual control, the above adjustment may be performed multiple times because the indoor air humidity is greater than the preset second humidity value and the ratio of the current ventilation volume of the air outlet of the fresh air device to the ventilation volume of the air inlet of the exhaust device is greater than the preset second threshold value.

[0062] In one embodiment, the ratio of the ventilation volume of the air outlet of the fresh air device to the ventilation volume of the air inlet of the exhaust device in step S102 is the ratio of the opening angle between the wind shield set in the air outlet of the fresh air device and the end face of the air outlet, and the opening angle between the wind shield set in the air inlet of the exhaust device and the end face of the air inlet.

[0063] Specifically, the opening angle of the wind shield directly affects the ventilation volume of the air outlet of the fresh air device and the ventilation volume of the air inlet of the exhaust device. When the opening angle increases, the ventilation volume increases accordingly, and vice versa. The opening angle of the wind shield in the air volume control mechanism can be controlled by a motor or the like. For this purpose, the ratio of the opening angle between the wind shield set in the air outlet of the fresh air device and the end face of the air outlet and the opening angle between the wind shield set in the air inlet of the exhaust device and the end face of the air inlet is used as the ratio of the ventilation volume of the air outlet of the fresh air device to the ventilation volume of the air inlet of the exhaust device. The ventilation volume can be effectively controlled by controlling the wind shield.

[0064] In one embodiment, in combination with the previous embodiment, increasing the ventilation volume of the air outlet of the fresh air device in step S102 includes: increasing the opening angle between the wind shield set in the air outlet of the fresh air device and the end face of the air outlet; reducing the ventilation volume of the air inlet of the exhaust device includes: reducing the opening angle between the wind shield set in the air inlet of the exhaust device and the end face of the air inlet.

[0065] Specifically, by increasing the opening angle between the wind shield provided in the air outlet of the fresh air device and the end face of the air outlet, the ventilation volume of the air outlet of the fresh air device can be increased by increasing the opening angle of the wind shield, so that the amount of outdoor humid air entering the room is increased, and the indoor air humidity is finally increased; by reducing the opening angle between the wind shield provided in the air inlet of the exhaust device and the end face of the air inlet, the amount of indoor air entering the exhaust device is reduced by reducing the opening angle of the wind shield, and the amount of indoor air discharged from the exhaust device is reduced, and the loss of moisture in the indoor air is finally avoided, which is conducive to increasing the indoor air humidity. The purpose of increasing the indoor air humidity when the indoor air humidity is lower than the first humidity value is achieved.

[0066] In one embodiment, reducing the ventilation volume of the air outlet of the fresh air device includes: reducing the opening angle between the wind shield set in the air outlet of the fresh air device and the end face of the air outlet; increasing the ventilation volume of the air inlet of the exhaust device includes: increasing the opening angle between the wind shield set in the air inlet of the exhaust device and the end face of the air inlet.

[0067] Specifically, reducing the opening angle between the wind shield provided in the air outlet of the fresh air device and the end face of the air outlet reduces the amount of fresh air discharged into the room from the air outlet, which can effectively reduce the amount of outdoor humid air entering the room, thus avoiding further increase of indoor air humidity; increasing the opening angle between the wind shield provided in the air inlet of the exhaust device and the end face of the air inlet, thus allowing more indoor air to enter the exhaust device and be discharged to the outdoors through the exhaust device, thus accelerating the discharge of indoor humid air when the indoor air humidity is high, ultimately helping to reduce indoor air humidity. In the above manner, the purpose of reducing indoor air humidity when the indoor air humidity is higher than the second humidity value is achieved.

[0068] In one embodiment, increasing the opening angle between the wind shield set in the air outlet of the fresh air device and the end face of the air outlet includes: increasing the opening angle by 1 to 10 degrees; reducing the opening angle between the wind shield set in the air inlet of the exhaust device and the end face of the air inlet includes: reducing the opening angle by 1 to 10 degrees.

[0069] In another embodiment, the opening angle between the wind shield set in the air outlet of the fresh air device and the end face of the air outlet is reduced, including: the opening angle is reduced by 1 to 10 degrees; the opening angle between the wind shield set in the air inlet of the exhaust device and the end face of the air inlet is increased, including: the opening angle is increased by 1 to 10 degrees.

[0070] It is worth mentioning that the unit angle of increase or decrease of the opening angle can be any value within the range of 1 to 10 degrees, such as 2 degrees, 4 degrees, 5 degrees, 7 degrees and the like. At the same time, the amount of increase or decrease of the opening angle should not be too small or too large. When the opening angle is less than 1 degree, it is easy to greatly increase the number of adjustments of the opening angle of the wind shield plate at the air outlet of the fresh air device and the opening angle of the wind shield plate at the air inlet of the exhaust device, resulting in a long-term operation of the air volume control mechanism to make the ratio of the opening angle of the wind shield plate at the air outlet of the fresh air device and the opening angle of the wind shield plate at the air inlet of the exhaust device within the range of the first threshold and the second threshold; if the unit angle of increase or decrease of the opening angle is too large, for example, greater than 10 degrees, it is easy to cause the adjustment amount of one adjustment to be too large. Although this method speeds up the adjustment speed of the indoor air humidity, the change in the ratio of the opening angle of the wind shield plate at the air outlet of the fresh air device and the opening angle of the wind shield plate at the air inlet of the exhaust device is too large, resulting in the problem of small adjustment accuracy due to large adjustment amount.

[0071] In one embodiment, the first threshold range is 0.3-0.5; the second threshold range is 0.6-0.8.

[0072] For the first threshold value within such a range, it is avoided that the first threshold value is too small, for example, it is less than 0.3, and the opening angle between the wind shield plate set in the air outlet of the fresh air device and the end face of the air outlet is finally obtained to be small, which may easily cause the ventilation volume of the air outlet of the fresh air device to be too small, and the amount of fresh air entering the room is small, and the ventilation effect cannot be achieved; for the second threshold value within such a range, it is avoided that the second threshold value is too large, for example, it is greater than 0.8, and the opening angle between the wind shield plate set in the air outlet of the fresh air device and the end face of the air outlet is finally obtained to be large, resulting in excessive ventilation volume of the air outlet of the fresh air device, and too much fresh air is introduced into the room, which makes the indoor temperature fluctuate greatly and reduces the comfort effect.

[0073] In one embodiment, the air supply mode of the air conditioner is started while increasing the ventilation volume of the air outlet of the fresh air device and / or reducing the ventilation volume of the air inlet of the exhaust device; the dehumidification mode of the air conditioner is started while reducing the ventilation volume of the air outlet of the fresh air device and / or increasing the ventilation volume of the air inlet of the exhaust device.

[0074] While controlling the ventilation volume of the air outlet of the fresh air device and the ventilation volume of the air inlet of the exhaust device, the air conditioning mode is used to assist in adjusting the indoor air humidity, accelerating the indoor air humidity to quickly enter the comfortable range; specifically, when the indoor air humidity is less than the preset first humidity value, when the opening angle of the wind shield is adjusted, the air supply mode of the air conditioner is turned on to improve the circulation of the indoor air, which is conducive to the outdoor humid air entering the room and quickly mixing with the original indoor air. Similarly, when the indoor air humidity is greater than the preset second humidity value, when the opening angle of the wind shield is adjusted, the dehumidification mode of the air conditioner is turned on to further reduce the indoor air humidity, so that the indoor air humidity can be reduced quickly.

[0075] The following examples are used to specifically illustrate the humidity control method provided by the present application:

[0076] The humidity information of indoor air is obtained by setting up humidity sensors;

[0077] The humidity information obtained by the humidity sensor is transmitted to the control system of the fresh air air conditioner. The first humidity value and the second humidity value suitable for the user are preset in the control system. The first humidity value RH1 is less than the second humidity value RH2. The control system can compare the indoor air humidity information obtained by the humidity sensor with the preset RH1 and RH2.

[0078] At the same time, a first threshold and a second threshold of the ratio of the ventilation volume of the air outlet 7 of the fresh air device 4 to the ventilation volume of the air inlet 8 of the exhaust device 5 are preset in the control system. The first threshold is smaller than the second threshold. The control system can calculate the ratio of the ventilation volume of the air outlet 7 of the fresh air device 4 to the ventilation volume of the air inlet 8 of the exhaust device 5.

[0079] The control system determines whether the air humidity is less than the preset RH1 or greater than the preset RH2, and at the same time determines whether the ratio of the ventilation volume of the air outlet 7 of the fresh air device 4 to the ventilation volume of the air inlet 8 of the exhaust device 5 is less than the first threshold or greater than the second threshold.

[0080] If the indoor humidity value is less than RH1, and at the same time, the ratio of the ventilation volume of the air outlet 7 of the current fresh air device 4 to the ventilation volume of the air inlet 8 of the exhaust device 5 is less than the preset first threshold value, the operation of increasing the indoor air humidity may be a method of increasing the ventilation volume of the air outlet 7 of the fresh air device 4 and keeping the ventilation volume of the air inlet 8 of the exhaust device 5 unchanged; it may be a method of keeping the ventilation volume of the air outlet 7 of the fresh air device 4 unchanged and reducing the ventilation volume of the air inlet 8 of the exhaust device 5; it may also be a method of increasing the ventilation volume of the air outlet 7 of the fresh air device 4 and reducing the ventilation volume of the air inlet 8 of the exhaust device 5; after the operation of increasing the indoor air humidity, if the indoor air humidity is still less than the preset RH1, the operation of increasing the indoor air humidity again is as described above.

[0081] If the indoor humidity value is greater than RH2, and at the same time, the ratio of the ventilation volume of the air outlet 7 of the current fresh air device 4 to the ventilation volume of the air inlet 8 of the exhaust device 5 is greater than the preset second threshold value, it is necessary to reduce the indoor air humidity. The specific method may be to keep the ventilation volume of the air outlet 7 of the fresh air device 4 unchanged and increase the ventilation volume of the air inlet 8 of the exhaust device 5; it may be to reduce the ventilation volume of the air outlet 7 of the fresh air device 4 and keep the ventilation volume of the air inlet 8 of the exhaust device 5 unchanged; it may also be to reduce the ventilation volume of the air outlet 7 of the fresh air device 4 and increase the ventilation volume of the air inlet 8 of the exhaust device 5; after lowering the indoor air humidity; if the indoor humidity is still greater than the preset RH2; then reduce the indoor air humidity again, and the specific method is as above.

[0082] The ratio of the ventilation volume of the air outlet 7 of the fresh air device 4 to the ventilation volume of the air inlet 8 of the exhaust device 5 may be the ratio of the opening angle φ1 between the wind shield provided in the air outlet 7 of the fresh air device 4 and the end face of the air outlet 7 to the opening angle φ2 between the wind shield provided in the air inlet 8 of the exhaust device 5 and the end face of the air inlet 8. Therefore, the preset first threshold and the second threshold may be the thresholds of the angle compensation amount φ obtained by the ratio of φ1 to φ2.

[0083] As described above, the ventilation volume of the air outlet 7 of the fresh air device 4 is increased, that is, the opening angle between the wind shield provided in the air outlet 7 of the fresh air device 4 and the end surface of the air outlet 7 is increased, that is, φ1 is increased;

[0084] Reduce the ventilation volume of the air inlet 8 of the exhaust device 5, that is, reduce the opening angle between the wind shield provided in the air inlet 8 of the exhaust device 5 and the end surface of the air inlet 8, that is, reduce φ2;

[0085] Reduce the ventilation volume of the air outlet 7 of the fresh air device 4, that is, reduce the opening angle between the wind shield provided in the air outlet 7 of the fresh air device 4 and the end surface of the air outlet 7, that is, reduce φ1;

[0086] To increase the ventilation volume of the air inlet 8 of the exhaust device 5, the opening angle between the wind shield plate provided in the air inlet 8 of the exhaust device 5 and the end surface of the air inlet 8 is increased, that is, φ2 is increased.

[0087] The preferred angle for increasing or decreasing φ1 and φ2 is 5°.

[0088] The first threshold provided in the present application may be 0.5; the second threshold range may be 0.7.

[0089] While the air volume control mechanism is used to adjust the humidity, the machine body 6 can also be used for auxiliary regulation. When the indoor air humidity is less than RH1 and φ is less than 0.5, φ1 is increased and / or φ2 is decreased, and the air supply mode of the air conditioner is started to increase the indoor air circulation speed.

[0090] When the indoor air humidity is greater than RH2 and φ is greater than 0.7, φ1 is reduced and / or φ2 is increased, and the dehumidification mode of the air conditioner is started to assist in regulating the indoor humidity.

[0091] Combined with Fig.10 The control method flow chart shown in FIG.

[0092] After the air conditioner is turned on, the fresh air device 4 and the exhaust device 5 start to work. At this time, the wind shields in the fresh air device 4 and the exhaust device 5 are opened. At the same time, the humidity sensor transmits the real-time indoor air humidity to the control system of the fresh air air conditioner. The control system calculates the real-time φ value based on the real-time φ1 and φ2. The control system determines whether RH is less than RH1 and whether φ is less than 0.5;

[0093] If so, φ1 is controlled to increase by 5° and φ2 is controlled to decrease by 5°, and the air conditioner is turned on in the air supply mode. After adjustment, if RH is less than RH1, φ1 is controlled to increase by 5° and φ2 is controlled to decrease by 5° again. After multiple adjustments, 0.5≤φ≤0.7, and φ approaches 0.7, RH1≤RH≤RH2, and finally the control system outputs angles Φ1 and Φ2, and the air conditioner does not turn on any mode.

[0094] If not, φ1 is controlled to decrease by 5° and φ2 is increased by 5°, and the air conditioner is turned on in dehumidification mode. If RH is greater than RH1 after adjustment, φ1 is controlled to decrease by 5° and φ2 is increased by 5° again; after multiple adjustments, 0.5≤φ≤0.7, and φ approaches 0.7, RH1≤RH≤RH2, and finally the control system outputs angles Φ1 and Φ2, and the air conditioner does not turn on any mode.
