Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and specifically provides a fresh air air conditioner. Background Technology

[0002] As users' demands for indoor air quality continue to rise, the simple cooling and heating functions of traditional air conditioners are no longer sufficient to meet these needs. Fresh air conditioners integrating temperature control and fresh air exchange have emerged as a result. However, current research on fresh air conditioners mainly focuses on the overall design and control methods, with significant shortcomings in outdoor environmental monitoring.

[0003] Currently, outdoor environmental monitoring devices are usually installed at the fresh air inlet of the outdoor unit or on the building wall, which exposes them directly to the external environment. They are easily affected by factors such as direct sunlight, airflow disturbances, and the temperature of the building wall, making it impossible for the outdoor environmental monitoring devices to truly and accurately reflect the outdoor environmental conditions, thereby affecting indoor comfort and air quality.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] This utility model aims to solve the aforementioned technical problem, namely, to address the issue in the prior art where the unreasonable installation location of outdoor environmental monitoring devices prevents them from accurately reflecting the outdoor environmental conditions. This application provides a fresh air conditioner, which includes:

[0006] Indoor unit;

[0007] The fresh air duct has a first end connected to the indoor unit and a second end extending through the building wall to the outside.

[0008] An outdoor environmental monitoring device is installed inside the fresh air duct; wherein the distance between the outdoor environmental monitoring device and the second end of the fresh air duct is L1, and the distance between the outdoor environmental monitoring device and the building wall is L2, where L1>0 and L2>0.

[0009] In the preferred technical solution of the above-mentioned fresh air air conditioner, 0.5cm≤L1≤2cm.

[0010] In the preferred technical solution of the above-mentioned fresh air air conditioner, 0.5cm≤L2≤2cm.

[0011] In the preferred technical solution of the above-mentioned fresh air air conditioner, a filter screen is provided at the second end of the fresh air duct.

[0012] In the preferred technical solution of the above-mentioned fresh air air conditioner, the pore size of the filter screen is D, where D>2.5μm.

[0013] In the preferred technical solution of the above-mentioned fresh air air conditioner, the minimum distance between the outdoor environmental monitoring device and the inner wall of the fresh air duct is L3, where L3>0mm.

[0014] In the preferred technical solution of the above-mentioned fresh air air conditioner, L3≥5mm.

[0015] In the preferred technical solution of the above-mentioned fresh air air conditioner, the outdoor environment monitoring device is installed in the fresh air duct by means of a bracket.

[0016] In the preferred technical solution of the above-mentioned fresh air air conditioner, the number of outdoor environmental monitoring components is one, which has a built-in temperature monitoring module and a PM2.5 monitoring module.

[0017] In the preferred technical solution of the above-mentioned fresh air air conditioner, the number of outdoor environmental monitoring devices is two, one of which is a temperature monitoring device and the other is a PM2.5 monitoring device.

[0018] Those skilled in the art will understand that the new air conditioner of this utility model, by placing the outdoor environmental monitoring component inside the fresh air duct and maintaining a certain distance between it and the second end of the fresh air duct and the building wall, can effectively prevent the outdoor environmental monitoring component from being directly exposed to the external environment, thereby eliminating the influence of interference factors such as direct sunlight and airflow disturbance. On the other hand, it can also block the influence of the building wall temperature on the outdoor environmental monitoring component, thereby ensuring that the outdoor environmental monitoring component can truly and accurately reflect the outdoor environmental status, improving the accuracy and reliability of the monitoring data, and helping to improve indoor comfort and indoor air quality.

[0019] Furthermore, by setting the distance between the outdoor environmental monitoring device and the second end of the fresh air duct between 0.5cm and 2cm, interference from factors such as direct sunlight, airflow disturbance, and large dust particles can be eliminated. On the other hand, the accuracy of outdoor environmental monitoring data can be improved, avoiding the problem of inaccurate monitoring data caused by the outdoor environmental monitoring device being too far from the second end of the fresh air duct.

[0020] Furthermore, by setting the distance between the outdoor environmental monitoring device and the building wall between 0.5cm and 2cm, it can be ensured that the outdoor environmental monitoring device can accurately reflect the outdoor environmental temperature and isolate the thermal interference of the building wall on the outdoor environmental monitoring device.

[0021] Furthermore, by installing a filter at the second end of the fresh air duct, particulate matter such as dust and sand can be intercepted. This prevents these particles from depositing on the outdoor environmental monitoring device and affecting its measurement accuracy, as well as from causing physical impact damage to the outdoor environmental monitoring device. On the other hand, it can also improve the filtration efficiency and service life of the filter in the fresh air air conditioner to a certain extent.

[0022] Furthermore, by setting the pore size of the filter screen to be greater than 2.5μm, it can effectively intercept large particles such as dust and sand, ensuring the measurement accuracy of the outdoor environmental monitoring device and preventing these particles from causing physical damage to the outdoor environmental monitoring device. On the other hand, it does not affect the outdoor environmental monitoring device's ability to monitor PM2.5 concentration in the outdoor environment.

[0023] Furthermore, by setting the minimum distance between the outdoor environmental monitoring device and the inner wall of the fresh air duct to be greater than 0 mm, the interference of the duct wall temperature on the outdoor environmental monitoring device can be isolated, ensuring that the outdoor environmental monitoring device can truly and accurately reflect the outdoor environmental status.

[0024] Furthermore, by setting the minimum distance between the outdoor environmental monitoring device and the inner wall of the fresh air duct to be greater than 5mm, the accuracy and reliability of the monitoring data can be further improved. Attached Figure Description

[0030] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0031] It should be noted that in the description of this application, the terms "upper", "lower", "inner", "bottom", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0032] Furthermore, it should be noted that, in the description of this application, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] like Figure 1 and Figure 2 As shown, to address the problem in existing technologies where the outdoor environmental monitoring component 3 cannot accurately reflect the outdoor environmental conditions due to its improper installation location, this application's fresh air conditioner includes an indoor unit 1, a fresh air duct 2, and an outdoor environmental monitoring component 3. The first end of the fresh air duct 2 is connected to the indoor unit 1, and the second end extends through the building wall 6 to the outside. The outdoor environmental monitoring component 3 is installed inside the fresh air duct 2; wherein the distance between the outdoor environmental monitoring component 3 and the second end of the fresh air duct 2 is L1, and the distance between the outdoor environmental monitoring component 3 and the building wall 6 is L2, where L1>0 and L2>0.

[0034] This application places the outdoor environmental monitoring device 3 inside the fresh air duct 2, maintaining a certain distance between it and the second end of the fresh air duct 2 and the building wall 6. On the one hand, this effectively prevents the outdoor environmental monitoring device 3 from being directly exposed to the external environment, thereby eliminating the influence of interference factors such as direct sunlight and airflow disturbance. On the other hand, it also blocks the influence of the temperature of the building wall 6 on the outdoor environmental monitoring device 3, thus ensuring that the outdoor environmental monitoring device can truly and accurately reflect the outdoor environmental conditions, improving the accuracy and reliability of monitoring data, and helping to improve indoor comfort and indoor air quality.

[0035] The following is further reference Figure 1-2 This paper describes a preferred embodiment of the fresh air conditioner according to this application. Those skilled in the art will understand that the embodiments described below are merely illustrative of the principles of this application and are not intended to limit the scope of protection of this application. Provided that the fresh air conditioner includes at least an indoor unit 1, a fresh air duct 2, and an outdoor environmental monitoring device 3, those skilled in the art can adjust the following configuration to make this application applicable to more specific application scenarios.

[0036] like Figure 1 As shown, the fresh air air conditioner includes an indoor unit 1 and a fresh air duct 2. The indoor unit 1 is equipped with an air inlet. The first end of the fresh air duct 2 is connected to the air inlet, and the second end extends through the building wall 6 to the outside, so that fresh outdoor air can be delivered to the indoor unit 1 through the fresh air duct 2.

[0037] The second end of the fresh air duct 2 is the outdoor fresh air inlet, which is used to introduce fresh outdoor air.

[0038] See next Figure 1 The fresh air conditioner also includes an outdoor environment monitoring component 3, which is installed inside the fresh air duct 2 and close to the second end of the duct. This avoids inaccurate data collection caused by the outdoor environment monitoring component 3 being too far from the second end of the fresh air duct 2, ensuring accurate collection of outdoor environmental parameters. The outdoor environment monitoring component 3 has built-in temperature and PM2.5 monitoring modules, enabling it to simultaneously monitor outdoor temperature and PM2.5 concentration. This allows the fresh air conditioner to adjust the air outlet temperature and fan speed in real time based on the outdoor temperature, and adjust the fresh air supply and volume based on the outdoor PM2.5 concentration, thereby ensuring both indoor air quality and improved indoor comfort.

[0039] Among them, the outdoor environmental monitoring device 3 has a built-in temperature monitoring module and a PM2.5 monitoring module, which means that the temperature monitoring module and the PM2.5 monitoring module are integrated on the same monitoring device, so that the monitoring device can monitor the outdoor environmental temperature and PM2.5 concentration at the same time.

[0040] Of course, the specific configuration of the outdoor environmental monitoring device 3 in this application is not fixed, and those skilled in the art can adjust it as needed. For example, there may be two outdoor environmental monitoring devices 3: one is a temperature monitoring device that monitors the outdoor ambient temperature, and the other is a PM2.5 monitoring device that monitors the PM2.5 concentration in the outdoor environment. When monitoring the outdoor ambient temperature, the temperature monitoring device can trigger the temperature adjustment function of the fresh air conditioner if it detects that the outdoor ambient temperature is too high or too low. When monitoring the particulate matter concentration in the outdoor environment, the PM2.5 monitoring device can activate the filter in the fresh air conditioner to filter the air when the PM2.5 concentration exceeds the standard.

[0041] See next Figure 2The distance between the outdoor environmental monitoring device 3 and the second end of the fresh air duct 2 is L1. Where 0.5cm≤L1≤2cm, by setting the distance between the outdoor environmental monitoring device 3 and the second end of the fresh air duct 2 between 0.5cm and 2cm, interference from factors such as direct sunlight and airflow disturbances can be eliminated, significantly improving the monitoring accuracy of parameters such as temperature and PM2.5 concentration by the outdoor environmental monitoring device 3. Furthermore, by rationally setting the positional relationship between the monitoring device and the fresh air inlet, the problem of inaccurate monitoring data due to excessive distance is avoided.

[0042] It should be noted that when there are two outdoor environmental monitoring devices 3, the distance between these two outdoor environmental monitoring devices 3 and the second end of the fresh air duct 2 should be set between 0.5cm and 2cm.

[0043] Of course, the specific distance between the outdoor environmental monitoring component 3 and the second end of the fresh air duct 2 is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the distance L1 between the outdoor environmental monitoring component 3 and the second end of the fresh air duct 2 can be greater than 0 cm and less than 0.5 cm, which can also effectively prevent the outdoor environmental monitoring component 3 from being directly exposed to the external environment, thereby eliminating the influence of interference factors such as direct sunlight and airflow disturbance.

[0044] See next Figure 2 The distance between the outdoor environmental monitoring device 3 and the building wall 6 is L2. Wherein, 0.5cm≤L2≤2cm, by setting the distance between the outdoor environmental monitoring device 3 and the building wall 6 between 0.5cm and 2cm, it can be ensured that the outdoor environmental monitoring device 3 accurately reflects the outdoor environmental temperature, and the problem of inaccurate monitoring data caused by thermal interference from the building wall 6 to the outdoor environmental monitoring device 3 can be avoided.

[0045] It should be noted that when there are two outdoor environmental monitoring devices 3, the distance between these two outdoor environmental monitoring devices 3 and the end of the building wall 6 should be set between 0.5cm and 2cm.

[0046] It should also be noted that the outdoor environmental monitoring component 3 is installed at the portion of the fresh air duct 2 that extends out of the building wall 6, and the distance L1 between the outdoor environmental monitoring component 3 and the second end of the fresh air duct 2 is between 0.5cm and 2cm, as is the distance L2 between the outdoor environmental monitoring component 3 and the building wall 6. This means that the axial dimension of the portion of the fresh air duct 2 extending out of the building wall 6 is between 1cm and 4cm. Therefore, the axial dimension of the portion of the fresh air duct 2 extending out of the building wall 6 needs to be determined based on the distances between the outdoor environmental monitoring component 3 and the building wall 6, and between the outdoor environmental monitoring component 3 and the second end of the fresh air duct 2.

[0047] Of course, the specific distance between the outdoor environmental monitoring device 3 and the building wall 6 is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the distance L2 between the outdoor environmental monitoring device 3 and the building wall 6 can be greater than 0 cm and less than 0.5 cm, which can, to a certain extent, avoid the problem of inaccurate monitoring data caused by thermal interference from the building wall 6 to the outdoor environmental monitoring device 3.

[0048] See next Figure 2 The outdoor environmental monitoring component 3 is installed inside the fresh air duct 2 via a bracket 4. This ensures that the outdoor environmental monitoring component 3 remains in non-contact with the duct wall of the fresh air duct 2, avoiding thermal interference from the fresh air duct 2 that could lead to inaccurate monitoring data. Specifically, the minimum distance between the outdoor environmental monitoring component 3 and the inner wall of the fresh air duct 2 is L3, where L3 ≥ 5mm. By setting the minimum distance between the outdoor environmental monitoring component 3 and the inner wall of the fresh air duct 2 to be greater than 5mm, the heat conduction path between the duct wall and the outdoor environmental monitoring component 3 can be effectively blocked, minimizing the interference of the duct wall temperature on the temperature data. This ensures that the outdoor environmental monitoring component 3 accurately reflects the outdoor environmental temperature, improving the accuracy and reliability of the monitoring data.

[0049] It should be noted that when there are two outdoor environmental monitoring devices 3, the minimum distance between these two outdoor environmental monitoring devices 3 and the inner wall of the fresh air duct 2 should be set to be greater than 5mm.

[0050] Of course, the minimum distance between the outdoor environmental monitoring component 3 and the inner wall of the fresh air duct 2 is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the minimum distance L3 between the outdoor environmental monitoring component 3 and the inner wall of the fresh air duct 2 can also be greater than 0 cm and less than 5 mm. This can also ensure that the outdoor environmental monitoring component 3 and the wall of the fresh air duct 2 remain in non-contact, avoiding heat conduction interference caused by direct contact between the outdoor environmental monitoring component 3 and the wall of the fresh air duct 2, so that the monitoring data of the outdoor environmental monitoring component 3 is not affected by the temperature of the wall of the fresh air duct 2. However, when the minimum distance L3 between the outdoor environmental monitoring component 3 and the inner wall of the fresh air duct 2 is greater than 0 cm and less than 5 mm, the thermal interference effect of the outdoor environmental monitoring component 3 on the inner wall of the fresh air duct 2 is greater than when the minimum distance L3 between the outdoor environmental monitoring component 3 and the inner wall of the fresh air duct 2 is greater than 5 mm.

[0051] It should be noted that, in order to further reduce the thermal interference of the fresh air duct 2 on the outdoor environmental monitoring device 3, the bracket 4 is made of heat-insulating material. By making the bracket 4 of heat-insulating material, it is possible to prevent the outdoor environmental monitoring device 3 from interfering with the measurement of the outdoor ambient temperature due to the heat conduction of the bracket 4.

[0052] See next Figure 1A filter screen 5 is installed at the second end of the fresh air duct 2. The pore size of the filter screen 5 is D, where D > 2.5 μm. By setting the pore size of the filter screen 5 to be greater than 2.5 μm, large particles such as dust and sand can be effectively intercepted, ensuring the measurement accuracy of the outdoor environmental monitoring device 3 and preventing these particles from causing physical damage to the outdoor environmental monitoring device 3. On the other hand, it does not affect the outdoor environmental monitoring device 3's ability to monitor the PM2.5 concentration in the outdoor environment.

[0053] Among them, filter 5, in the process of intercepting dust, sand and other particulate matter, not only prevents these particles from depositing on the outdoor environmental monitoring device 3 and affecting the measurement accuracy of the outdoor environmental monitoring device 3, but also prevents these particles from causing physical impact damage to the outdoor environmental monitoring device 3. In addition, the setting of filter 5 improves the filtration efficiency and service life of the filter in the fresh air air conditioner to a certain extent.

[0054] It should be noted that this application does not limit the number of filter screens 5, as long as the filter screens 5 can intercept large particles such as dust and sand without affecting the outdoor environmental monitoring device 3's monitoring of PM2.5 concentration in the outdoor environment. For example, the number of filter screens 5 can be one, two, or other numbers. When there are two or more filter screens 5, these filter screens 5 can be arranged sequentially along the airflow direction.
