Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fresh air machines, for example to a method and device for installing a fresh air machine, a fresh air machine and a storage medium. BACKGROUND

[0002] At present, more than 80% of people spend time indoors. The standard in China stipulates that the per capita fresh air volume in the room should not be less than 30m3 / h. However, at present, most of the residences in China do not install fresh air systems, and the ventilation means only adopts the local exhaust of the kitchen and bathroom or the way of opening the window for ventilation. Studies have shown that relying only on the above means cannot meet the minimum demand for indoor fresh air. Therefore, it is necessary to install a fresh air system in residential buildings. Compared with other buildings, residential buildings have lower floor height and smaller installation space, and it is more difficult to adopt the air volume distribution mode of the general ventilation system. At present, the air volume distribution of the fresh air system in the actual project only relies on engineering experience to judge, and it is impossible to ensure that the air volume of each room meets the standard, resulting in differences in the fresh air intake of each room.

[0003] The related technology discloses a kind of air volume distribution static pressure tank of fresh air system and its installation method, including box, cover plate and wind baffle, box is dug with wind baffle installation groove, wind baffle includes sleeve plate and telescopic plate, telescopic plate is slidably installed in sleeve plate, sleeve plate is detachably installed in wind baffle installation groove, the side wall on the side of box is dug with air inlet, the other side wall on the box is dug with air outlet, by the setting of wind baffle, the airflow in the box is shielded, it is convenient to distribute the air volume of the airflow in static pressure tank, so that the air volume of each air outlet remains substantially the same, by changing the relative position of telescopic plate and sleeve plate, the wind baffle area of wind baffle is changed, it is convenient to debug static pressure tank during installation, improve the efficiency of installation and debugging.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] Although the related technology can make the air intake of each room the same, in actual application, different rooms not only have different areas, but also have different environmental conditions. If a one-size-fits-all installation method is used to make the air intake of each room the same, it may appear that the PM2.5 concentration adjustment of some rooms is fast, and the PM2.5 concentration adjustment of some rooms is slow. If PM2.5 concentration adjustment testing is performed for each room respectively, the PM2.5 concentration in the ventilation duct and the room may be different, which affects the test results, resulting in inaccurate installation and poor user experience.

[0006] It is to be understood that the information disclosed in the Background section is merely for the purpose of enhancing the understanding of the present application and thus can include information that is not prior art to those skilled in the art. SUMMARY

[0007] The following presents a simplified summary of some aspects of the disclosed embodiments in order to provide a basic understanding of such embodiments. The summary is not an extensive overview of the application. It is not intended to identify key / critical elements of the embodiments or to delineate the scope of the embodiments but to present some aspects of the disclosed embodiments in a simplified form as a prelude to the more detailed description that is presented later.

[0008] The embodiments of the present disclosure provide a method and device for installing a fresh air machine, a fresh air machine and a storage medium, so as to reduce the influence of different room areas and environmental parameters on PM2.5 concentration adjustment of the fresh air machine, improve the accuracy of installation test of PM2.5 concentration adjustment of each room, and improve user experience.

[0009] In some embodiments, the fresh air machine comprises ventilation ducts in communication with different indoor spaces; the method comprises: adjusting the PM2.5 concentrations in the ventilation ducts and the indoor spaces until the PM2.5 concentration difference between the ventilation ducts and the indoor spaces is less than a set threshold; opening the ventilation ducts in a set order, adjusting the PM2.5 concentrations of the indoor spaces corresponding to the ventilation ducts, and recording the fourth time length for the PM2.5 concentrations of the indoor spaces to reach a set concentration; and adjusting the setting parameters of the indoor spaces according to the fourth time length.

[0010] In some embodiments, the device comprises a processor and a memory storing program instructions, and the processor is configured to execute the method for installing the fresh air machine when executing the program instructions.

[0011] In some embodiments, the fresh air machine comprises:

[0012] a fresh air machine body, the fresh air machine comprising ventilation ducts in communication with different indoor spaces; and

[0013] The device for installing the fresh air machine is installed on the fresh air machine body.

[0014] In some embodiments, the storage medium stores program instructions, and the program instructions execute the method for installing the fresh air machine when running.

[0015] The method and device for installing the fresh air machine, the fresh air machine and the storage medium provided by the embodiments of the present disclosure can achieve the following technical effects:

[0016] The PM2.5 concentrations in the ventilation ducts and the indoor spaces are adjusted until the difference between the PM2.5 concentrations in the ventilation ducts and the indoor spaces is less than a set threshold, then the ventilation ducts are opened in a set order, the PM2.5 concentrations in the indoor spaces corresponding to the ventilation ducts are adjusted, and the fourth time length for the PM2.5 concentrations in the indoor spaces to reach a set concentration is recorded. Since the fourth time length can represent the ability of the fresh air machine to change the PM2.5 concentration in the indoor space under the influence of different areas and different environmental parameters of the rooms, setting the parameters of the rooms based on the fourth time length can make the installation of the fresh air machine match the situation of the rooms. The influence of different areas and environmental parameters of the rooms on the PM2.5 concentration adjustment of the fresh air machine is reduced. Moreover, the PM2.5 concentrations in the ventilation ducts and the indoor spaces are adjusted to the same range before the PM2.5 concentration test, which reduces the influence of the initial PM2.5 concentrations in the ventilation ducts and the indoor spaces on the test, improves the accuracy of the test, and improves the user experience.

The wearable device can include, for example, a smart watch, a smart bracelet, a pedometer, etc.

[0033] The disclosed embodiments of the present disclosure provide a new fan, comprising: an air inlet and a ventilation air duct communicating with different indoor spaces, the ventilation air duct comprising a supply air duct and an exhaust air duct. The air inlet is used for the new fan to introduce outdoor fresh air into each ventilation air duct. The indoor space comprises a fresh air inlet communicating with the supply air duct and an exhaust air outlet communicating with the exhaust air duct.

[0034] In combination with Figure 1 As shown, the disclosed embodiments provide a method for installing a new fan, comprising:

[0035] S01, the new fan opens each ventilation air duct in a set order and adjusts the indoor environmental temperature of each ventilation air duct corresponding to the indoor space.

[0036] S02, the new fan records the first time length for the indoor environmental temperature of each indoor space to reach the set temperature.

[0037] S03, the new fan adjusts the setting parameters of each indoor space according to the first time length.

[0038] Before the new fan opens each ventilation air duct in a set order and adjusts the indoor environmental temperature of each ventilation air duct corresponding to the indoor space, the method further comprises: the new fan adjusts the temperature in each ventilation air duct and each indoor space until the temperature difference between each ventilation air duct and each indoor space is less than a set threshold.

[0039] In the embodiments of the present disclosure, the adjustment object can be replaced by other environmental parameters, such as carbon dioxide concentration, humidity, and PM2.5 concentration, etc., or a combination of any number of environmental parameters. For example, the adjustment object can be carbon dioxide concentration and humidity, carbon dioxide concentration, humidity, and PM2.5 concentration, temperature, carbon dioxide concentration, humidity, and PM2.5 concentration, etc. Correspondingly, the set temperature will also change to the set value of the corresponding environmental parameter, such as set humidity, set carbon dioxide concentration, or set PM2.5 concentration, etc. Specifically, the fresh air machine adjusts the environmental parameters in each ventilation duct and each indoor space until the difference between the environmental parameters in each ventilation duct and each indoor space is less than the set threshold. The fresh air machine opens each ventilation duct in the set order and adjusts the environmental parameters of the corresponding indoor space of each ventilation duct. The fresh air machine records the current time length for the environmental parameters of each indoor space to reach the set environmental parameters. The fresh air machine adjusts the setting parameters of each indoor space according to the current time length. Specifically, the environmental parameters of each indoor space can be adjusted by an air conditioner or a fresh air machine, and the environmental parameters in each ventilation duct can be adjusted by a fresh air machine.

[0040] By using the method for installing a fresh air machine provided in the embodiments of the present disclosure, each ventilation duct is opened in a set order, the indoor environmental temperature of the corresponding indoor space of each ventilation duct is adjusted, and the first time length for the indoor environmental temperature of each indoor space to reach the set temperature is recorded. Finally, the setting parameters of each indoor space are adjusted according to the first time length. Since the first time length can represent the ability of the fresh air machine to change the indoor environmental temperature under the influence of different areas and different environmental parameters of each room, setting the parameters of each room based on the first time length can match the installation of the fresh air machine with the situation of each room. Thus, the influence of different areas and environmental parameters of each room on the operation of the fresh air machine is reduced, and the user experience is improved.

[0041] Optionally, the fresh air machine sets the installation parameters of each indoor space according to the first time length, including: the fresh air machine sorts the first time lengths of each indoor space according to the sizes of the first time lengths; and the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the first time lengths and the areas of each indoor space.

[0042] In this way, the fresh air machine sorts the first time lengths of each indoor space according to the sizes of the first time lengths. Since the sorting result can represent the air supply or air exhaust effect of each indoor space, and the area of each indoor space affects the first time length, adjusting the setting parameters of each indoor space according to the sorting result of the first time lengths and the areas of each indoor space can be based on the actual situation of the areas of each indoor space and the current channel and parameter setting situation of the fresh air machine, to obtain more accurate parameters, thereby improving the installation effect.

[0043] Optionally, the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the first time length and the area of each indoor space, including: the fresh air machine compares whether the sorting result of the first time length and the sorting result of the area of each indoor space are consistent; the fresh air machine adjusts the setting parameters of each indoor space corresponding to the ventilation air duct according to the first time length and the area of each indoor space in the case that the sorting result of the first time length and the sorting result of the area of each indoor space are consistent; the fresh air machine reminds the installer in the case that the sorting result of the first time length and the sorting result of the area of each indoor space are inconsistent; wherein, the setting parameters include the air volume and the air speed in the ventilation channel corresponding to each indoor space.

[0044] In this way, the fresh air machine compares whether the sorting result of the first time length and the sorting result of the area of each indoor space are consistent, since the sorting result can represent the air supply or air exhaust effect of each indoor space, and the area of each indoor space is usually positively correlated with the first time length, while the ventilation effect and the air exhaust effect are related to the corresponding setting relationship of the ventilation air duct and each indoor space and the parameter setting relationship of each indoor space, so by comparing whether the sorting results are consistent, it can be detected whether the installation of the ventilation air duct of each indoor space is incorrect. Therefore, the fresh air machine reminds the installer to check or re-set the corresponding setting relationship of the ventilation air duct and each indoor space in the case that the sorting result of the second time length and the sorting result of the area of each indoor space are inconsistent. In the case that the sorting result of the second time length and the sorting result of the area of each indoor space are consistent, the corresponding setting relationship of the ventilation air duct and each indoor space is correct at this time, so the setting parameters of each indoor space corresponding to the ventilation air duct are adjusted according to the second time length and the area of each indoor space, so that the air supply or air exhaust effect of each indoor space meets the user's demand.

[0045] Optionally, the fresh air machine opens each ventilation air duct in a set order and adjusts the indoor environment temperature of each indoor space corresponding to each ventilation air duct, including: the fresh air machine opens each ventilation air duct and adjusts the indoor environment temperature of each indoor space corresponding to each ventilation air duct in turn; or, the fresh air machine opens each ventilation air duct and adjusts the indoor environment temperature of each indoor space corresponding to each ventilation air duct at the same time.

[0046] In this way, the fresh air machine opens each ventilation air duct and adjusts the indoor environment temperature of each indoor space corresponding to each ventilation air duct in turn, which can make each temperature adjustment more accurate. The fresh air machine opens each ventilation air duct and adjusts the indoor environment temperature of each indoor space corresponding to each ventilation air duct at the same time, which can increase the efficiency of temperature adjustment test.

[0047] Optionally, the fresh air machine adjusts the indoor environment temperature of each indoor space corresponding to each ventilation air duct, including: when the ventilation air duct is an air supply air duct, the fresh air machine opens the fresh air outlet and closes the indoor doors and windows to supply air to each indoor space at a reference air volume; when the ventilation air duct is an air exhaust air duct, the fresh air machine opens the air exhaust outlet and closes the indoor doors and windows to exhaust air from each indoor space at a reference air volume.

[0048] The fresh air machine determines the current season, and determines the ventilation air duct as the supply air duct or the exhaust air duct according to the current season. Specifically, when the current season is winter, the fresh air machine determines the ventilation air duct as the exhaust air duct, so that the hot air in the room can be exhausted to increase the temperature of the heat exchange core of the fresh air machine and prevent condensation. When the current season is summer, the fresh air machine determines the ventilation air duct as the supply air duct, so that the air with a higher temperature can be supplied into the room to increase the temperature of the heat exchange core of the fresh air machine and prevent condensation. The way in which the fresh air machine determines the current season includes but is not limited to determining the season according to the current time, determining the season according to the outdoor environment temperature, or determining the season according to the user instruction.

[0049] In this way, when the ventilation air duct is the supply air duct, the fresh air machine needs to supply air to the room at this time, so the fresh air machine opens the fresh air outlet and closes the indoor doors and windows to supply air to each indoor space at the reference air volume. When the ventilation air duct is the exhaust air duct, the fresh air machine needs to exhaust air at this time, so the fresh air machine opens the exhaust air outlet and closes the indoor doors and windows to exhaust air to each indoor space at the reference air volume. Each indoor space is supplied or exhausted by the same reference air volume, which can avoid the influence of the current setting parameters of the ventilation air duct on the supply air effect and the exhaust air effect, so as to consider the influence of the area of each indoor space and the indoor environment parameters on the supply air effect and the exhaust air effect, and make the parameter setting of each indoor space more accurate.

[0050] Optionally, before adjusting the indoor environment temperature of each indoor space corresponding to each ventilation air duct, the fresh air machine opens each ventilation air duct in a set order, and further includes: determining the reference air volume according to the indoor environment temperature and the outdoor environment temperature of each indoor space.

[0051] The fresh air machine determines the reference air volume according to the indoor environment temperature and the outdoor environment temperature of each indoor space, including: calculating the temperature difference between the outdoor environment temperature and the indoor environment temperature, and determining the first air volume corresponding to the temperature difference as the reference air volume.

[0052] In this way, the fresh air machine determines the reference air volume according to the indoor environment temperature and the outdoor environment temperature of each indoor space, so that the reference air volume can be matched with the indoor and outdoor environment temperature, thereby improving the efficiency of the temperature adjustment test.

[0053] Optionally, the fresh air machine records the first time length required for the indoor environment temperature of each indoor space to reach the set temperature, including: obtaining the first time when each indoor space starts to adjust the temperature; obtaining the second time when the indoor environment temperature of each indoor space reaches the set temperature; and determining the difference between the second time and the first time of each indoor space as the first time length corresponding to each indoor space.

[0054] In this way, the fresh air machine calculates a difference between the first time at which temperature adjustment is started and the second time at which the set temperature is reached, and determines the above difference as the first duration corresponding to each indoor space, so that the time required for the fresh air machine to adjust the temperature of each indoor space to the set temperature can be obtained.

[0055] In combination Figure 2 As shown in the drawings, the embodiment of the present disclosure provides a method for installing a fresh air machine, comprising:

[0056] S21, the fresh air machine adjusts the carbon dioxide concentration of each ventilation air duct corresponding indoor space to a first concentration.

[0057] S22, the fresh air machine opens each ventilation air duct in a set order, adjusts the carbon dioxide concentration of each indoor space to a set concentration, and records the second duration of the carbon dioxide concentration of each indoor space reaching the set concentration.

[0058] S23, the fresh air machine adjusts the setting parameters of each indoor space according to the second duration.

[0059] In the method for installing a fresh air machine, before the fresh air machine opens each ventilation air duct in a set order and adjusts the carbon dioxide concentration of each indoor space to a set concentration and records the second duration of the carbon dioxide concentration of each indoor space reaching the set concentration, the method further comprises: the fresh air machine adjusts the carbon dioxide concentration in each ventilation air duct until the carbon dioxide concentration difference in each ventilation air duct is less than a set threshold.

[0060] In the method for installing a fresh air machine, the carbon dioxide concentration of each ventilation air duct corresponding indoor space is adjusted to a first concentration, each ventilation air duct is opened in a set order, the carbon dioxide concentration of each indoor space is adjusted to a set concentration, and the second duration of the carbon dioxide concentration of each indoor space reaching the set concentration is recorded. Finally, the setting parameters of each indoor space are adjusted according to the second duration. Since the second duration can represent the ability of the fresh air machine to change the carbon dioxide concentration in each room under the influence of different areas and different environmental parameters, setting the parameters of each room based on the second duration can match the installation of the fresh air machine with the situation of each room. The influence of different areas and environmental parameters on the carbon dioxide concentration adjustment of the fresh air machine is reduced. Moreover, adjusting each indoor space to the same first concentration before the carbon dioxide concentration test reduces the influence of the different initial carbon dioxide concentrations of each indoor space on the test, improves the accuracy of the test, and improves the user experience.

[0061] Optionally, the fresh air machine adjusts the carbon dioxide concentration of each ventilation air duct corresponding indoor space to a first concentration, comprising: the fresh air machine starts the maximum operating power to supply air or exhaust air to each indoor space; in the case that the carbon dioxide concentration of each indoor space reaches the first concentration, the fresh air machine stops supplying air or exhausting air.

[0062] In this way, by starting the maximum operating power, each indoor space can quickly reach the first concentration, thereby saving test time.

[0063] Optionally, the fresh air machine adjusts the setting parameters of each indoor space according to the second time length, including: the fresh air machine sorts the second time lengths of each indoor space according to the sizes of the second time lengths; and the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the second time lengths and the areas of each indoor space.

[0064] In this way, since the sorting result can represent the air supply or air exhaust effect of each indoor space, and the area of each indoor space affects the second time length, adjusting the setting parameters of each indoor space according to the sorting result of the second time lengths and the areas of each indoor space can be based on the actual situation of the areas of each indoor space and the current channel and parameter setting situation of the fresh air machine, to obtain more accurate parameters, thereby improving the installation effect.

[0065] Optionally, the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the second time lengths and the areas of each indoor space, including: the fresh air machine compares whether the sorting result of the second time lengths and the sorting result of the areas of each indoor space are consistent; the fresh air machine adjusts the setting parameters of the corresponding ventilation air ducts of each indoor space according to the second time lengths and the areas of each indoor space in the case that the sorting result of the second time lengths and the sorting result of the areas of each indoor space are consistent; and the fresh air machine reminds the installer in the case that the sorting result of the second time lengths and the sorting result of the areas of each indoor space are inconsistent; wherein the setting parameters include the air volume and air speed in the corresponding ventilation channels of each indoor space.

[0066] In this way, the fresh air machine compares whether the sorting result of the second time lengths and the sorting result of the areas of each indoor space are consistent, since the sorting result can represent the air supply or air exhaust effect of each indoor space, and the area of each indoor space is usually positively correlated with the second time length, while the ventilation effect and the air exhaust effect are related to the corresponding setting relationship between the ventilation air ducts and each indoor space and the parameter setting relationship of each indoor space. Therefore, by comparing whether the sorting results are consistent, it can be detected whether the installation of the ventilation air ducts of each indoor space is incorrect. Therefore, the fresh air machine reminds the installer to check or re-set the corresponding setting relationship between the ventilation air ducts and each indoor space in the case that the sorting result of the second time lengths and the sorting result of the areas of each indoor space are inconsistent. In the case that the sorting result of the second time lengths and the sorting result of the areas of each indoor space are consistent, the corresponding setting relationship between the ventilation air ducts and each indoor space is correct at this time, and therefore the fresh air machine adjusts the setting parameters of the corresponding ventilation air ducts of each indoor space according to the second time lengths and the areas of each indoor space, so that the air supply or air exhaust effect of each indoor space meets the user's demand.

[0067] Optionally, the fresh air machine adjusts the setting parameters of the ventilation air ducts corresponding to the indoor spaces according to the second time length and the areas of the indoor spaces, including: the fresh air machine determines a first correction parameter according to a difference between the second time length and the reference time length; the fresh air machine determines a second correction parameter according to the areas of the indoor spaces; and the fresh air machine corrects the setting parameters of the ventilation air ducts corresponding to the indoor spaces according to the first correction parameter and the second correction parameter.

[0068] In this way, the difference between the second time length and the reference time length can represent the difference between the current air supply and exhaust effect and the required air supply or exhaust effect. Therefore, the fresh air machine can determine the first correction parameter according to the difference between the second time length and the reference time length, so that the first correction parameter can be matched with the current air supply or exhaust effect of the fresh air machine. Since the area of the indoor space can affect the air supply or exhaust effect of the fresh air machine, the fresh air machine can determine the second correction parameter according to the area of the indoor space, so that the second correction parameter can be matched with the area of the indoor space. Thus, the fresh air machine can correct the setting parameters of the ventilation air ducts corresponding to the indoor spaces according to the first correction parameter and the second correction parameter, so that the fresh air machine can be set from two dimensions of the current operation effect and the area of the indoor space, thereby improving the installation effect.

[0069] Optionally, the fresh air machine compares whether the sorting results of the second time length and the areas of the indoor spaces are consistent, including: the fresh air machine sorts the areas of the indoor spaces according to the sizes of the areas of the indoor spaces; the fresh air machine determines a first position of the areas of the indoor spaces and a second position of the corresponding second time length; and the fresh air machine determines that the sorting results of the second time length and the areas of the indoor spaces are consistent in the case that the first position and the second position are the same.

[0070] In this way, the fresh air machine sorts the areas of the indoor spaces according to the sizes of the areas of the indoor spaces, determines a first position of the areas of the indoor spaces and a second position of the corresponding second time length, and determines that the sorting results of the second time length and the areas of the indoor spaces are consistent in the case that the first position and the second position are the same. By comparing the first position and the second position, whether the corresponding setting relationship between the ventilation air ducts and the indoor spaces is incorrect can be detected.

[0071] Optionally, the fresh air machine opens the ventilation air ducts according to a set order and adjusts the carbon dioxide concentrations of the indoor spaces to a set concentration, including: the fresh air machine opens the ventilation air ducts and adjusts the carbon dioxide concentrations of the indoor spaces corresponding to the ventilation air ducts in turn; or the fresh air machine opens the ventilation air ducts and adjusts the carbon dioxide concentrations of the indoor spaces corresponding to the ventilation air ducts at the same time.

[0072] In this way, the fresh air machine opens each ventilation air duct, and adjusts the carbon dioxide concentration of each ventilation air duct corresponding to the indoor space in turn, so that the carbon dioxide concentration adjustment is more accurate each time. The fresh air machine opens each ventilation air duct, and adjusts the carbon dioxide concentration of each ventilation air duct corresponding to the indoor space at the same time, so that the efficiency of the carbon dioxide concentration adjustment test is increased.

[0073] In combination Figure 3 As shown in the drawings, the embodiment of the present disclosure provides a method for installing a fresh air machine, comprising:

[0074] S31, the fresh air machine adjusts the humidity in each ventilation air duct until the humidity difference in each ventilation air duct is less than a set threshold.

[0075] S32, the fresh air machine opens each ventilation air duct in a set order, adjusts the indoor environmental humidity of each ventilation air duct corresponding to the indoor space, and records the third time length for the indoor environmental humidity of each indoor space to reach the set humidity.

[0076] S33, the fresh air machine adjusts the setting parameters of each indoor space according to the third time length.

[0077] The method for installing a fresh air machine provided by the embodiment of the present disclosure is used to adjust the humidity in each ventilation air duct until the humidity difference in each ventilation air duct is less than a set threshold, then open each ventilation air duct in a set order, adjust the indoor environmental humidity of each ventilation air duct corresponding to the indoor space, and record the third time length for the indoor environmental humidity of each indoor space to reach the set humidity, and finally adjust the setting parameters of each indoor space according to the third time length. Since the third time length can represent the ability of the fresh air machine to change the indoor humidity under the influence of different areas and different environmental parameters of each room, setting the parameters of each room based on the third time length can make the installation of the fresh air machine match the situation of each room. Reduce the influence of different areas and environmental parameters of each room on the humidity adjustment of the fresh air machine. Moreover, adjusting the humidity in each ventilation air duct to the same range before the humidity test reduces the influence of the different initial humidity in each ventilation air duct on the test, improves the accuracy of the test, and improves the user experience.

[0078] Optionally, the fresh air machine adjusts the humidity in each ventilation air duct until the humidity difference in each ventilation air duct is less than a set threshold, comprising: the fresh air machine opens the air inlet and closes the fresh air inlet of each indoor space; the fresh air machine runs in the fresh air mode at the maximum operating power; the fresh air machine closes the fresh air mode and the air inlet when the humidity difference in each ventilation air duct is less than the set threshold.

[0079] In this way, the fresh air machine opens the air inlet, introduces outdoor fresh air into each ventilation air duct. Close the fresh air inlet of each indoor space to avoid the fresh air in the ventilation air duct entering the indoor space and affecting the indoor environment. The fresh air machine runs in fresh air mode according to the maximum operating power, introduces fresh air into each ventilation air duct, thereby adjusting the environmental parameters in each ventilation air duct. In the case where the humidity difference in each supply air duct is less than the set threshold value, the humidity in each ventilation air duct is the same at this time, so the fresh air mode and the air inlet are closed.

[0080] Optionally, the fresh air machine sets the installation parameters of each indoor space according to the third time length, including: the fresh air machine sorts the third time length of each indoor space according to the size of the third time length; the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the third time length and the area of each indoor space.

[0081] In this way, the fresh air machine sorts the third time length of each indoor space according to the size of the third time length, and adjusts the setting parameters of each indoor space according to the sorting result of the third time length and the area of each indoor space. Since the sorting result can represent the supply air or exhaust air effect of each indoor space, and the area of each indoor space affects the third time length, adjusting the setting parameters of each indoor space according to the sorting result of the third time length and the area of each indoor space can be based on the actual situation of the area of each indoor space and the current channel and parameter setting of the fresh air machine. More accurate parameters can improve the installation effect.

[0082] Optionally, the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the third time length and the area of each indoor space, including: the fresh air machine compares whether the sorting result of the third time length and the sorting result of the area of each indoor space are consistent; the fresh air machine adjusts the setting parameters of the corresponding ventilation air duct of each indoor space according to the second time length and the area of the indoor space in the case where the sorting result of the third time length and the area of the indoor space is consistent; the fresh air machine reminds the installer in the case where the sorting result of the third time length and the area of the indoor space is inconsistent; wherein the setting parameters include the air volume and air speed in the ventilation channel corresponding to each indoor space.

[0083] In this way, the new fan compares whether the sorting result of the third time length and the sorting result of the area of each indoor space are consistent. Since the sorting result can represent the air supply or air exhaust effect of each indoor space, and the area of each indoor space is usually positively correlated with the third time length, and the ventilation effect and the air exhaust effect are related to the corresponding setting relationship of the ventilation air duct and each indoor space and the parameter setting relationship of each indoor space, therefore, by comparing whether the sorting results are consistent, it can be detected whether the installation error of the corresponding setting relationship of the ventilation air duct and each indoor space occurs. Therefore, in the case that the sorting result of the third time length and the area of the indoor space is inconsistent, the new fan reminds the installer to check or re-set the corresponding setting relationship of the ventilation air duct and each indoor space. In the case that the sorting result of the third time length and the area of the indoor space is consistent, at this time, the corresponding setting relationship of the ventilation air duct and each indoor space is correct, therefore, according to the third time length and the area of the indoor space, the setting parameters of the corresponding ventilation air duct of each indoor space are adjusted, so that the air supply or air exhaust effect of each indoor space meets the user's demand.

[0084] Optionally, before the new fan opens each ventilation air duct in the set order, the new fan further comprises: adjusting the indoor environment humidity of each indoor space corresponding to each ventilation air duct to a first humidity.

[0085] In this way, adjusting each indoor space to the same first humidity before the humidity test reduces the influence of the different initial humidity of each indoor space on the test, improves the accuracy of the test, and improves the user experience.

[0086] Optionally, the new fan adjusts the indoor environment humidity of each indoor space corresponding to each ventilation air duct to a first humidity, comprising: the new fan starts the maximum operating power to supply air or exhaust air to each indoor space; and the new fan stops supplying air or exhausting air when the indoor environment humidity of each indoor space reaches the first humidity.

[0087] In this way, the new fan starts the maximum operating power to supply air or exhaust air to each indoor space, so as to quickly adjust the humidity of each indoor space and improve the efficiency of the humidity adjustment test. When the indoor environment humidity of each indoor space reaches the first humidity, the humidity of each indoor space is the same, which reduces the influence of the initial humidity of each indoor space on the humidity adjustment test, and therefore the air supply or air exhaust is stopped.

[0088] Optionally, the new fan opens each ventilation air duct in the set order and adjusts the indoor environment humidity of each indoor space corresponding to each ventilation air duct, comprising: the new fan opens each ventilation air duct and adjusts the indoor environment humidity of each indoor space corresponding to each ventilation air duct in turn; or the new fan opens each ventilation air duct and adjusts the indoor environment humidity of each indoor space corresponding to each ventilation air duct at the same time.

[0089] In this way, the fresh air machine opens each ventilation air duct, and adjusts the indoor environment humidity of the indoor space corresponding to each ventilation air duct in turn, so that each humidity adjustment is more accurate. The fresh air machine opens each ventilation air duct, and adjusts the indoor environment humidity of the indoor space corresponding to each ventilation air duct at the same time, so that the efficiency of the humidity adjustment test is increased.

[0090] In combination Figure 4 As shown in the drawings, the embodiment of the present disclosure provides a method for installing a fresh air machine, comprising:

[0091] S41, the fresh air machine adjusts the PM2.5 concentration in each ventilation air duct and each indoor space until the PM2.5 concentration difference in each ventilation air duct and each indoor space is less than a set threshold.

[0092] S42, the fresh air machine opens each ventilation air duct in a set order, adjusts the PM2.5 concentration of the indoor space corresponding to each ventilation air duct, and records the fourth time length used for the PM2.5 concentration of each indoor space to reach a set concentration.

[0093] S43, the fresh air machine adjusts the setting parameters of each indoor space according to the fourth time length.

[0094] The method for installing a fresh air machine provided by the embodiment of the present disclosure is used to adjust the PM2.5 concentration in each ventilation air duct and each indoor space until the PM2.5 concentration difference in each ventilation air duct and each indoor space is less than a set threshold, then each ventilation air duct is opened in a set order, the PM2.5 concentration of the indoor space corresponding to each ventilation air duct is adjusted, and the fourth time length used for the PM2.5 concentration of each indoor space to reach a set concentration is recorded, and finally the setting parameters of each indoor space are adjusted according to the fourth time length. Since the fourth time length can represent the ability of the fresh air machine to change the indoor PM2.5 concentration under the influence of different areas and different environmental parameters of each room, setting the parameters of each room based on the fourth time length can match the installation of the fresh air machine with the situation of each room. The influence of different areas and environmental parameters of each room on the PM2.5 concentration adjustment of the fresh air machine is reduced. Moreover, the PM2.5 concentration in each ventilation air duct and each indoor space is adjusted to the same range before the PM2.5 concentration test, which reduces the influence of the initial PM2.5 concentration difference between each ventilation air duct and each indoor space on the test, improves the accuracy of the test, and improves the user experience.

[0095] Optionally, the fresh air machine adjusts the PM2.5 concentration in each ventilation air duct and each indoor space, comprising: the fresh air machine adjusts the PM2.5 concentration of the indoor space corresponding to each ventilation air duct to a second concentration; the fresh air machine opens the air inlet and closes the fresh air outlet of each indoor space, and runs in the fresh air mode at the maximum operating power; the fresh air machine closes the fresh air mode and the air inlet when the PM2.5 concentration difference in each ventilation air duct is less than a set threshold.

[0096] In this way, the fresh air machine adjusts the PM2.5 concentration of each indoor space corresponding to the ventilation air duct to the second concentration, reducing the influence of the initial PM2.5 concentration of each indoor space on the PM2.5 concentration adjustment test of the fresh air machine. The fresh air machine opens the air inlet and closes the fresh air outlet of each indoor space, runs in fresh air mode at maximum operating power, and in the case that the PM2.5 concentration difference in each air supply duct is less than the set threshold value, the PM2.5 concentration in each air supply duct is the same at this time, so the fresh air mode and the air inlet are closed, reducing the influence of the initial PM2.5 concentration in each ventilation air duct on the PM2.5 concentration adjustment test.

[0097] Optionally, the fresh air machine adjusts the PM2.5 concentration of each indoor space corresponding to the ventilation air duct to the second concentration, comprising: the fresh air machine starts the maximum operating power to supply air or exhaust air to each indoor space; the fresh air machine stops supplying air or exhausting air when the PM2.5 concentration of each indoor space reaches the second concentration.

[0098] In this way, the fresh air machine starts the maximum operating power to supply air or exhaust air to each indoor space, and stops supplying air or exhausting air when the PM2.5 concentration of each indoor space reaches the second concentration. By starting the maximum operating power, the PM2.5 concentration of each indoor space can quickly reach the second concentration, thereby saving test time.

[0099] Optionally, the fresh air machine sets the installation parameters of each indoor space according to the fourth time length, comprising: the fresh air machine sorts the fourth time length of each indoor space according to the size of the fourth time length; the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the fourth time length and the area of each indoor space.

[0100] In this way, since the sorting result can represent the air supply or exhaust effect of each indoor space, and the area of each indoor space affects the fourth time length, the fresh air machine sorts the fourth time length of each indoor space according to the size of the fourth time length, and adjusts the setting parameters of each indoor space according to the sorting result of the fourth time length and the area of each indoor space. Based on the actual situation of the area of each indoor space and the current channel and parameter setting situation of the fresh air machine, more accurate parameters can be obtained, thereby improving the installation effect.

[0101] Optionally, the fresh air machine adjusts the setting parameters of each indoor space according to the sorting result of the fourth time length and the area of each indoor space, including: the fresh air machine compares whether the sorting result of the fourth time length and the sorting result of the area of each indoor space are consistent; the fresh air machine adjusts the setting parameters of each indoor space corresponding to the ventilation duct according to the fourth time length and the area of each indoor space in the case that the sorting result of the fourth time length and the sorting result of the area of each indoor space are consistent; the fresh air machine reminds the installer in the case that the sorting result of the fourth time length and the sorting result of the area of each indoor space are inconsistent; wherein the setting parameters include the air volume and air speed in the ventilation channel corresponding to each indoor space.

[0102] In this way, the fresh air machine compares whether the sorting result of the fourth time length and the sorting result of the area of each indoor space are consistent, since the sorting result can represent the air supply or exhaust effect of each indoor space, and the area of each indoor space is usually positively correlated with the fourth time length, while the ventilation effect and the exhaust effect are related to the corresponding setting relationship of the ventilation duct and each indoor space and the parameter setting relationship of each indoor space, therefore by comparing whether the sorting results are consistent, it can be detected whether the installation error occurs in the setting of the ventilation duct of each indoor space. Therefore, the fresh air machine reminds the installer to check or re-set the corresponding setting relationship of the ventilation duct and each indoor space in the case that the sorting result of the fourth time length and the sorting result of the area of each indoor space are inconsistent. In the case that the sorting result of the fourth time length and the sorting result of the area of each indoor space are consistent, the corresponding setting relationship of the ventilation duct and each indoor space is correct at this time, therefore the setting parameters of each indoor space corresponding to the ventilation duct are adjusted according to the fourth time length and the area of each indoor space, so that the air supply or exhaust effect of each indoor space meets the user's demand.

[0103] Optionally, the fresh air machine opens each ventilation duct in a set order and adjusts the PM2.5 concentration of each indoor space corresponding to each ventilation duct, including: the fresh air machine opens each ventilation duct and adjusts the PM2.5 concentration of each indoor space corresponding to each ventilation duct in turn; or the fresh air machine opens each ventilation duct and adjusts the PM2.5 concentration of each indoor space corresponding to each ventilation duct at the same time.

[0104] In this way, the fresh air machine opens each ventilation duct and adjusts the PM2.5 concentration of each indoor space corresponding to each ventilation duct in turn, which can make each PM2.5 concentration adjustment more accurate. The fresh air machine opens each ventilation duct and adjusts the PM2.5 concentration of each indoor space corresponding to each ventilation duct at the same time, which can increase the efficiency of PM2.5 concentration adjustment test.

[0105] Optionally, the fresh air machine adjusts the PM2.5 concentration of each indoor space corresponding to the ventilation air duct, including: when the ventilation air duct is a supply air duct, the fresh air machine opens the fresh air outlet, closes the indoor doors and windows, and supplies air to each indoor space at a reference air volume; when the ventilation air duct is an exhaust air duct, the fresh air machine opens the exhaust air outlet, closes the indoor doors and windows, and exhausts air from each indoor space at a reference air volume.

[0106] The fresh air machine determines the current season, and determines whether the ventilation air duct is a supply air duct or an exhaust air duct according to the current season. Specifically, when the current season is winter, the fresh air machine determines that the ventilation air duct is an exhaust air duct, so that the hot air in the room can be exhausted to increase the temperature of the heat exchange core of the fresh air machine and prevent condensation; when the current season is summer, the fresh air machine determines that the ventilation air duct is a supply air duct, so that air with a higher temperature can be supplied into the room to increase the temperature of the heat exchange core of the fresh air machine and prevent condensation. The way in which the fresh air machine determines the current season includes but is not limited to determining the season according to the current time, determining the season according to the outdoor environment temperature, or determining the season according to user instructions.

[0107] In this way, when the ventilation air duct is a supply air duct, the fresh air machine needs to supply air to the room at this time, so the fresh air machine opens the fresh air outlet, closes the indoor doors and windows, and supplies air to each indoor space at a reference air volume. When the ventilation air duct is an exhaust air duct, the fresh air machine needs to exhaust air at this time, so the fresh air machine opens the exhaust air outlet, closes the indoor doors and windows, and exhausts air from each indoor space at a reference air volume. Each indoor space is supplied or exhausted with the same reference air volume, which can avoid the influence of the current setting parameters of the ventilation air duct on the supply and exhaust effects, so that the influence of the area of each indoor space and the indoor environment parameters on the supply and exhaust effects can be considered separately, and the parameter setting of each indoor space can be more accurate.
