[0050] The present invention provides a control method for a plant-conditioning room. The room comprises a housing defining a storage space for placing plants, and a ventilation outlet formed in the housing that communicates with a first air conditioning unit within a room. Specifically, the air conditioning room control method of the present invention obtains a first oxygen concentration within the storage space and a second oxygen concentration within the room in which the room is located. Only when the first oxygen concentration is greater than or equal to the second oxygen concentration is the air in the storage space discharged through the ventilation outlet to the first air conditioning unit, whereupon the air is then delivered into the room through the air outlet of the first air conditioning unit.

The first air-conditioning indoor unit is usually an important device used by users to improve the indoor space environment. It has a high-power air flow drive device, and its air outlet is located at a high height. Therefore, it can blow the air from the accommodation space over a longer distance and to a larger area, which is conducive to the uniform distribution of the air in the accommodation space in the indoor space, thereby improving the uniformity of the indoor air improvement effect of the air in the accommodation space. In addition, if the air temperature, humidity and other parameters in the accommodation space are significantly different from those in the indoor space, the air parameters from the accommodation space can be appropriately adjusted by the first air-conditioning indoor unit before being sent into the indoor space, avoiding large fluctuations in the temperature, humidity and other parameters of the indoor space that may cause discomfort to the user.

[0065] The present invention first provides a control method for a plant air-conditioning room. Figure 1 and Figure 2 Schematic diagrams of the plant air-conditioning room in different states according to one embodiment of the present invention. Figures 1 to 2The air-conditioning room 1 includes a housing 10 defining an accommodation space 11. The housing 10 is provided with a ventilation outlet 15. The ventilation outlet 15 is connected to a first air-conditioning indoor unit 2 in the indoor space where the air-conditioning room 1 is located. Specifically, the ventilation outlet 15 and the first air-conditioning indoor unit 2 can be connected via a fresh air duct 3.

[0066] The control method of the present invention is designed based on the air-conditioning room 1 having the above-mentioned structure and connection relationship.

[0067] The control method of the plant air-conditioning room of the present invention comprises:

[0068] Obtaining a first oxygen concentration in the accommodating space 11 and a second oxygen concentration in the indoor space where the air-conditioning room 1 is located; and

[0069] When the first oxygen concentration is higher than or equal to the second oxygen concentration, the air in the accommodating space 11 is discharged to the first air conditioning indoor unit 2 through the ventilation outlet 15 , so that the air is sent into the indoor space through the air outlet of the first air conditioning indoor unit 2 .

[0070] The air-conditioning room control method of the present invention obtains a first oxygen concentration within the accommodation space 11 and a second oxygen concentration within the indoor space where the air-conditioning room 1 is located. Only when the first oxygen concentration is greater than or equal to the second oxygen concentration does the method discharge the air within the accommodation space 11 toward the first air-conditioning indoor unit 2 through the ventilation outlet 15, and then deliver the air into the indoor space through the air outlet of the first air-conditioning indoor unit 2. In other words, when the first oxygen concentration within the accommodation space 11 is high (e.g., greater than or equal to the second oxygen concentration within the indoor space), the air within the accommodation space 11 is equivalent to oxygen-enriched fresh air for the indoor space. Therefore, delivering this oxygen-enriched fresh air into the indoor space can effectively improve the air environment within the indoor space. When the oxygen concentration within the accommodation space 11 is low, the air within the accommodation space 11 is not delivered into the indoor space.

[0071] Compared with the prior art, the present invention specifically delivers only the air with a higher oxygen content in the accommodating space 11 into the indoor space, greatly improving the air improvement effect of the plants.

[0072] More importantly, the oxygen-enriched fresh air within the accommodation space 11 of the air-conditioned room 1 is not discharged directly into the indoor space. Instead, it is transported to the first air-conditioning indoor unit 2 within the indoor space where the air-conditioning room 1 is located, and then delivered into the indoor space through the air outlet of the first air-conditioning indoor unit 2. This fully utilizes the locational and functional advantages of the first air-conditioning indoor unit 2. The first air-conditioning indoor unit 2 is typically an important device used by users to improve the indoor environment. It has a high-powered airflow drive device, and its air outlet is located at a higher height. Therefore, it can blow air from the accommodation space 11 over a longer distance and over a larger area, which is conducive to the uniform distribution of air within the accommodation space 11 within the indoor space and improves the uniformity of the indoor air quality improvement effect of the air within the accommodation space 11. Furthermore, if the temperature, humidity, or other parameters of the air within the accommodation space 11 differ significantly from those of the indoor space, the first air-conditioning indoor unit 2 can adjust the air parameters from the accommodation space 11 appropriately before delivering it into the indoor space, avoiding large fluctuations in the temperature, humidity, and other parameters of the indoor space that may cause user discomfort.

[0073] Specifically, Figure 3 FIG is a schematic flow chart of a control method for a plant air-conditioning room according to an embodiment of the present invention. Figure 3 In a specific embodiment, the control method of the present invention includes:

[0074] Step S10, obtaining a first oxygen concentration in the accommodating space 11 and a second oxygen concentration in the indoor space where the air-conditioning room 1 is located; and

[0075] Step S20, determining whether the first oxygen concentration is higher than or equal to the second oxygen concentration; if so, proceeding to step S30; if not, returning to step S10;

[0076] In step S30 , the air in the accommodating space 11 is discharged to the first air-conditioning indoor unit 2 through the ventilation outlet 15 , so that the air is sent into the indoor space through the air outlet of the first air-conditioning indoor unit 2 .

[0077] Figure 4 is a schematic cross-sectional view of an air-conditioning room according to one embodiment of the present invention. In some embodiments, the air-conditioning room 1 further includes a fresh air blower 80. The air inlet of the fresh air blower 80 communicates with the accommodating space 11, and the air outlet of the fresh air blower 80 communicates with the ventilation outlet 15. In other words, the fresh air blower 80 is configured to controllably draw air from the accommodating space 11 and blow it toward the ventilation outlet 15.

[0078] In these embodiments, the step of discharging the air in the accommodating space 11 to the first air-conditioning indoor unit 2 through the ventilation outlet 15 may specifically include:

[0079] Start the fresh air fan 80.

[0080] When the fresh air blower 80 is started, it draws air from the accommodating space 11 and blows it toward the ventilation outlet 15. Since the ventilation outlet 15 is connected to the first air conditioning indoor unit 2, the air flow blown out from the ventilation outlet 15 flows toward the first air conditioning indoor unit 2 and flows into the indoor space from the air outlet of the second air conditioning indoor unit 2.

[0081] Figure 5 1 is a schematic structural diagram of an air-conditioning room and a first air-conditioning indoor unit in another orientation according to an embodiment of the present invention. In order to facilitate the illustration of the internal structure of the first air-conditioning indoor unit, Figure 5 Partial structures of the first indoor air conditioning unit are omitted. In other embodiments, the first indoor air conditioning unit 2 is provided with a fresh air blower 80'. The air inlet of the fresh air blower 80' is connected to the ventilation outlet 15, and the air outlet of the fresh air blower 80' is connected to the air outlet of the first indoor air conditioning unit 2. In other words, the fresh air blower 80' is configured to draw air from the ventilation outlet 15 and blow air toward the air outlet of the first indoor air conditioning unit 2.

[0082] In these embodiments, the step of discharging the air in the accommodating space 11 to the first air-conditioning indoor unit 2 through the ventilation outlet 15 may specifically include:

[0083] A fresh air start-up instruction is sent to the first air-conditioning indoor unit 2 to instruct the fresh air blower 80' to start operating.

[0084] When the first air conditioning indoor unit 2 receives the fresh air start command, it controls the fresh air blower 80' to start operating. Once started, the fresh air blower 80 draws air from the ventilation outlet 15 and blows it toward the air outlet of the first air conditioning indoor unit 2. Because the ventilation outlet 15 is connected to the accommodating space 11, the air drawn by the fresh air blower 80' through the ventilation outlet 15 originates from the accommodating space 11.

[0085] It can be understood that the air flowing into the first air-conditioning indoor unit 2 from the ventilation outlet 15 can undergo some functional treatment (such as heating, cooling, filtering, sterilization, deodorization, humidification, dehumidification, aromatherapy, etc.) before flowing out from its air outlet, or it can flow out directly from its air outlet without undergoing any functional treatment.

[0086] exist Figure 3 In the illustrated embodiment, when the first oxygen concentration is lower than the second oxygen concentration, the process automatically returns to step S10. That is, when the oxygen concentration in the accommodating space 11 is lower than the oxygen concentration in the indoor space of the air-conditioning room 1, air is not supplied to the first air-conditioning indoor unit 2, and no measures are taken to improve the oxygen concentration in the accommodating space 11. This operating mode is the automatic fresh air mode.

[0087] In other embodiments, the air-conditioning room 1 further includes a plant growth lamp 70 disposed in the housing 10 (see Figure 9In these embodiments, when the first oxygen concentration is lower than the second oxygen concentration, the control method of the present invention further includes: turning on the plant growth lamp 70.

[0088] Turning on the plant growth lamp 70 can provide supplementary light to the accommodating space 11 , thereby promoting photosynthesis of the plants in the accommodating space 11 , allowing the plants to produce more oxygen, which is beneficial to increasing the oxygen concentration in the accommodating space 11 .

[0089] Specifically, Figure 6 FIG is a schematic flow chart of a control method for a plant air-conditioning room according to another embodiment of the present invention. Figure 6 In another specific embodiment, the control method of the present invention includes:

[0090] Step S10, obtaining a first oxygen concentration in the accommodating space 11 and a second oxygen concentration in the indoor space where the air-conditioning room 1 is located; and

[0091] Step S20, determining whether the first oxygen concentration is higher than or equal to the second oxygen concentration; if so, proceeding to step S30; if not, proceeding to step S40;

[0092] Step S30: exhausting the air in the accommodating space 11 to the first air-conditioning indoor unit 2 through the ventilation outlet 15, so that the air is sent into the indoor space through the air outlet of the first air-conditioning indoor unit 2;

[0093] Step S31, turn on the plant growth lamp 70, and return to step S10.

[0094] exist Figure 6 In the illustrated embodiment, when the first oxygen concentration is lower than the second oxygen concentration, the plant growth lamp 70 is activated to promote plant photosynthesis, thereby actively increasing the oxygen concentration within the accommodating space 11. This causes the first oxygen concentration to rise to a value greater than or equal to the second oxygen concentration as quickly as possible, thereby rapidly delivering oxygen-enriched fresh air from the accommodating space 11 to the first air conditioning indoor unit 2. This operating mode is a manual fresh air mode manually set by the user.

[0095] In some embodiments, the housing 10 includes a main body 10a having an entrance 10a1 and a door 10b for closing and / or opening the entrance 10a1. In these embodiments, the control method of the present invention further includes:

[0096] The control door body 10b is continuously in the closed state.

[0097] That is, no matter whether the first oxygen concentration is higher than or equal to the second oxygen concentration, the door 10 b is always in a closed state, so as to form two environments with different oxygen concentrations inside and outside the air-conditioned room 1 .

[0098] In some embodiments, a second air-conditioning indoor unit 20 is provided in the accommodating space 11. In these embodiments, the control method of the present invention further includes:

[0099] Acquire a first temperature in the accommodating space 11 and a second temperature in the indoor space where the air-conditioning room 1 is located;

[0100] When the first temperature exceeds the preset temperature range, the operation mode of the air-conditioning indoor unit 20 is adjusted according to the first temperature and the second temperature;

[0101] The operating modes of the air-conditioning indoor unit 20 include at least heating mode, cooling mode and natural air supply mode; in heating mode and cooling mode, the air-conditioning indoor unit 20 causes the air flow inside the accommodating space 11 to flow into the accommodating space 11 after heat exchange; in natural air supply mode, the air-conditioning indoor unit 20 causes the air flow in the external space where the air-conditioning room 1 is located to flow directly into the accommodating space 11.

[0102] The air-conditioning room control method of the present invention obtains the first temperature in the accommodating space 11 and the second temperature in the space where the air-conditioning room 1 is located. When the first temperature in the accommodating space 11 exceeds the preset temperature range, it means that the temperature in the accommodating space 11 is not suitable for plant growth. At this time, the operation mode of the air-conditioning indoor unit 20 can be adjusted according to the size of the first temperature and the second temperature and the size relationship between the two, so that the temperature of the accommodating space 11 is more suitable for plant growth, reducing the user's energy investment, making up for the user's lack of planting experience, and improving the user's confidence and fun in planting plants.

[0103] More importantly, the air conditioning indoor unit 20 operates in not only traditional cooling and heating modes but also a natural ventilation mode. In this mode, the air conditioning indoor unit 20 directs airflow from the space outside the air conditioning room 1 into the accommodating space 11 without undergoing heat exchange. This cleverly utilizes the air environment outside the air conditioning room 1, significantly reducing energy consumption in the air conditioning room 1 and lowering the cost of growing plants for users.

[0104] Figure 7 FIG is a schematic flow chart of a control method for a plant air-conditioning room according to another embodiment of the present invention. Figure 7 In another specific embodiment, the control method of the plant air-conditioning room of the present invention includes:

[0105] Step S10, obtaining a first oxygen concentration in the accommodating space 11 and a second oxygen concentration in the indoor space where the air-conditioning room 1 is located; and

[0106] Step S20, determining whether the first oxygen concentration is higher than or equal to the second oxygen concentration; if so, proceeding to step S30;

[0107] Step S30: exhausting the air in the accommodating space 11 to the first air-conditioning indoor unit 2 through the ventilation outlet 15, so that the air is sent into the indoor space through the air outlet of the first air-conditioning indoor unit 2;

[0108] Step S40, obtaining a first temperature in the accommodating space 11 and a second temperature in the space where the air-conditioning room 1 is located;

[0109] Step S50, determining whether the first temperature is within a preset temperature range; if so, returning to step S10; if not, going to step S60; and

[0110] Step S60: adjusting the operation mode of the air-conditioning indoor unit 20 according to the first temperature and the second temperature.

[0111] In some embodiments, step S60 of adjusting the operating mode of the air-conditioning indoor unit 20 according to the first temperature and the second temperature may specifically include:

[0112] If the first temperature is greater than the maximum endpoint value of the preset temperature range, and the temperature difference between the first temperature and the second temperature is greater than or equal to the first preset temperature value, the air conditioning indoor unit 20 is controlled to operate in the natural air supply mode;

[0113] If the first temperature is lower than the minimum endpoint value of the preset temperature range, and the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value, the air conditioning indoor unit 20 is controlled to operate in the natural air supply mode;

[0114] If the first temperature is greater than the maximum endpoint value of the preset temperature range, and the temperature difference between the first temperature and the second temperature is less than the first preset temperature value, the air conditioning indoor unit 20 is controlled to operate in the cooling mode;

[0115] If the first temperature is lower than the minimum endpoint value of the preset temperature range, and the temperature difference between the second temperature and the first temperature is lower than the first preset temperature value, the air conditioning indoor unit 20 is controlled to operate in the heating mode.

[0116] Specifically, when the first temperature is greater than the maximum endpoint of the preset temperature range, it indicates that the temperature within the air-conditioning room 1 is too high to be suitable for plant growth within the accommodation space 11. At this point, if the first temperature is higher than the second temperature, and the temperature difference between the first and second temperatures is large, it indicates that the temperature within the ambient space of the air-conditioning room 1 is relatively low. The air within this ambient space can be fully utilized to appropriately lower the temperature within the accommodation space 11, thereby making it conducive to plant growth. Therefore, at this point, the air-conditioning indoor unit 20 operates in natural air supply mode. Simply by using the airflow drive device of the air-conditioning indoor unit 20 to deliver external air into the accommodation space 11, the temperature within the accommodation space 11 can be effectively improved. Heat exchange with this air is not required, effectively reducing the energy consumption of the air-conditioning indoor unit 20. On the contrary, if the temperature difference between the first temperature and the second temperature is small, or even the first temperature is lower than the second temperature, and it means that the temperature in the environmental space where the air-conditioning room 1 is located is not much different from the temperature in the air-conditioning room 1, or even higher than the temperature in the air-conditioning room 1, the air in the environmental space where the air-conditioning room 1 is located cannot effectively improve the temperature in the accommodating space 11. At this time, controlling the air-conditioning indoor unit 20 to operate in cooling mode can effectively reduce the temperature in the accommodating space 11, making it more conducive to plant growth.

[0117] When the first temperature is less than the minimum endpoint of the preset temperature range, it indicates that the temperature within the air-conditioning room 1 is low and unsuitable for plant growth within the accommodation space 11. At this point, if the first temperature is lower than the second temperature, and the temperature difference between the second temperature and the first temperature is large, it indicates that the temperature within the ambient space of the air-conditioning room 1 is relatively high. The air within this ambient space can be fully utilized to appropriately raise the temperature within the accommodation space 11, thereby making it conducive to plant growth. Therefore, at this point, the air-conditioning indoor unit 20 operates in natural air supply mode. Simply by using the airflow drive device of the air-conditioning indoor unit 20 to deliver external air into the accommodation space 11, the temperature within the accommodation space 11 can be effectively improved. Heat exchange with this air is not required, effectively reducing the energy consumption of the air-conditioning indoor unit 20. On the contrary, if the temperature difference between the second temperature and the first temperature is small, or even when the first temperature is higher than the second temperature, and it means that the temperature in the environmental space where the air-conditioning room 1 is located is not much different from the temperature in the air-conditioning room 1, or even lower than the temperature in the air-conditioning room 1, the air in the environmental space where the air-conditioning room 1 is located cannot effectively improve the temperature in the accommodating space 11. At this time, controlling the air-conditioning indoor unit 20 to operate in heating mode can effectively increase the temperature in the accommodating space 11, making it more conducive to plant growth.

[0118] Specifically, Figure 8 FIG1 is a schematic flow chart of adjusting the operation mode of an air conditioner indoor unit according to a first temperature and a second temperature according to an embodiment of the present invention. Figure 8 The step of adjusting the operation mode of the air-conditioning indoor unit 20 according to the first temperature and the second temperature may specifically include:

[0119] Step S601, determining whether the first temperature is greater than the maximum endpoint value of the preset temperature range; if so, proceeding to step S611; if not, proceeding to step S621;

[0120] Step S611, calculating the temperature difference between the first temperature and the second temperature;

[0121] Step S612, determining whether the temperature difference between the first temperature and the second temperature is greater than or equal to a first preset temperature value; if so, proceeding to step S631; if not, proceeding to step S632;

[0122] Step S631, controlling the air conditioner indoor unit to operate in natural air supply mode;

[0123] Step S632, controlling the air conditioner indoor unit to operate in cooling mode;

[0124] Step S621, calculating the temperature difference between the second temperature and the first temperature;

[0125] Step S622, determining whether the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value; if so, proceeding to step S631; if not, proceeding to step S633;

[0126] Step S633: Control the air conditioner indoor unit to operate in heating mode.

[0127] It is understood that the execution of step S601 is premised on the first temperature being outside the preset temperature range. If the determination result of step S601 is negative, i.e., the first temperature is less than the maximum endpoint of the preset temperature range, then the first temperature is definitely less than the minimum endpoint of the preset temperature range, and there is no need to compare the first temperature with the minimum endpoint of the preset temperature range.

[0128] It should be noted that step S601 may also compare whether the first temperature is greater than the minimum endpoint value of the preset temperature range. If so, the first temperature must be greater than the maximum endpoint value of the preset temperature range, and other control logic remains unchanged.

[0129] Figure 9 and Figure 10 They are schematic partial structural cross-sectional views of a plant air-conditioning chamber in different situations according to one embodiment of the present invention, Figure 11 1 is a schematic exploded view of an air conditioner indoor unit according to an embodiment of the present invention. In some embodiments, a ventilation inlet 12 is provided on the housing 10. The ventilation inlet 12 connects the accommodating space 11 in the housing 10 with the ambient space where the housing 10 is located.

[0130] Furthermore, the air conditioning indoor unit 20 includes a housing 21, an air duct adjustment mechanism 22, and an airflow drive device 24. The housing 21 is provided with a first air inlet 211 that communicates with the accommodating space 11 and is isolated from the ventilation inlet 12; a second air inlet 212 that communicates with the ventilation inlet 12 and is isolated from the accommodating space 11; and at least one air outlet that communicates with the accommodating space 11. Specifically, the first air inlet 211 communicates only with the accommodating space 11 and not with the ventilation inlet 12. The first air inlet 211 only allows air within the accommodating space 11 to pass through and enter the housing 21. The second air inlet 212 communicates only with the ventilation inlet 12 and not with the accommodating space 11. The second air inlet 212 only allows air within the indoor space where the housing 10 is located (i.e., the indoor space where the air-conditioned room 1 is located) to pass through and enter the housing 21. The number of the air outlet may be one or more, and each air outlet is communicated with the accommodating space 11 to discharge the air in the casing 21 into the accommodating space 11 .

[0131] The airflow driving device 24 is disposed in the housing 21 and is used to drive the airflow in a controlled manner.

[0132] The air passage regulating mechanism 22 is movably disposed in the housing 21 and has a first state (a) in which the first air inlet 211 is opened and the second air inlet 212 is blocked. Figure 10 The second state (shown in FIG. 21 ) in which the second air inlet 212 is opened and the first air inlet 211 is blocked Figure 9 The air path of the air-conditioning room 1 is adjusted by switching the air path adjustment mechanism 22.

[0133] The housing 21 of the air conditioning indoor unit 20 has two air inlets. A first air inlet 211 communicates with the accommodating space 11 and is isolated from the ventilation inlet 12 on the outer shell 10. A second air inlet 212 is isolated from the accommodating space 11 and communicates with the ventilation inlet 12 on the outer shell 10. In other words, the air conditioning indoor unit 20 allows air from the accommodating space 11 to enter through the first air inlet 211, while also allowing air from outside the air-conditioned room 1 to enter through the second air inlet 212. Furthermore, an air flow control mechanism 22 is provided within the housing 21, which can be switched to open and close the first and second air inlets 211, 212.

[0134] Based on the air-conditioning room 1 having the above structure, the steps of controlling the air-conditioning indoor unit 20 to operate in the natural air supply mode may specifically include:

[0135] Only the airflow driving device 24 is activated, and the air path regulating mechanism 22 is adjusted to its second state. That is, in the natural air supply mode, the compressor of the air conditioner indoor unit 20 is not activated, and no refrigerant flows through the heat exchanger of the air conditioner indoor unit 20, and no heat exchange occurs with the air flow passing through it.

[0136] Based on the air-conditioning room 1 having the above structure, the steps of controlling the air-conditioning indoor unit 20 to operate in the heating mode or the cooling mode may specifically include:

[0137] The airflow drive device 24 and the compressor of the air conditioner indoor unit 20 are activated, and the air path adjustment mechanism 22 is adjusted to the first state. That is, in both heating and cooling modes, the airflow drive device 24 and the compressor are activated, allowing refrigerant to flow through the heat exchanger of the air conditioner indoor unit 20, thereby exchanging heat with the airflow passing through the heat exchanger. It will be appreciated that the refrigerant flow direction differs between heating and cooling modes. Since this technology is well known in the art, it will not be further described here.

[0138] In summary, in this embodiment, the switching of the operating mode of the air conditioner indoor unit 120 is achieved by switching the state of the air duct regulating mechanism 22. The present invention cleverly achieves switching of the operating mode of the air conditioner indoor unit 120 by providing a special first air inlet 211 and a second air inlet 212 on the housing 21 and providing the air duct regulating mechanism 22. The structure is very simple, and the state switching process of the air duct regulating mechanism 22 is simple and easy to control.

[0139] In some embodiments, the airflow driving device 24 is a fan. Specifically, the airflow driving device 24 can be a cross-flow fan, an axial flow fan, or a centrifugal fan.

[0140] Furthermore, in natural air supply mode, the fan speed is inversely correlated with the absolute value of the temperature difference between the first temperature and the second temperature. That is, the greater the absolute value of the temperature difference between the first temperature and the second temperature, the greater the temperature compensation provided by a unit volume of air from outside the air-conditioned room 1, and the lower the fan speed; conversely, the higher the fan speed.

[0141] Furthermore, in the heating mode, the fan speed is inversely related to the first temperature. That is, the higher the first temperature, the less heat required in the accommodating space 11, and the lower the fan speed; conversely, the fan speed is higher.

[0142] Furthermore, in the cooling mode, the fan speed is positively correlated with the first temperature. That is, the higher the first temperature, the more heat is required in the accommodating space 11, and the higher the fan speed; conversely, the fan speed is lower.

[0143] In some embodiments, the air conditioner indoor unit 20 further includes a heat exchanger 23 movably disposed in the casing 21 .

[0144] In these embodiments, when the air conditioner indoor unit 20 operates in the natural air supply mode, the control method of the present invention further includes:

[0145] The heat exchanger 23 is adjusted to be in the air flow path where the second air inlet 212 is located.

[0146] When the air conditioner indoor unit 20 operates in cooling mode or heating mode, the control method of the present invention further includes:

[0147] The heat exchanger 23 is adjusted to be in the air flow path where the first air inlet 211 is located.

[0148] Specifically, Figure 12 is a schematic flow chart of adjusting the operation mode of the air conditioner indoor unit according to the first temperature and the second temperature according to another embodiment of the present invention. Figure 12 The step of adjusting the operation mode of the air-conditioning indoor unit 20 according to the first temperature and the second temperature may specifically include:

[0149] Step S601, determining whether the first temperature is greater than the maximum endpoint value of the preset temperature range; if so, proceeding to step S611; if not, proceeding to step S621;

[0150] Step S611, calculating the temperature difference between the first temperature and the second temperature;

[0151] Step S612, determining whether the temperature difference between the first temperature and the second temperature is greater than or equal to a first preset temperature value; if so, proceeding to step S631'; if not, proceeding to step S632';

[0152] Step S631′, controlling the air conditioner indoor unit 20 to operate in the natural air supply mode, and adjusting the heat exchanger 23 to the air flow path where the second air inlet 212 is located;

[0153] Step S632′, controlling the air conditioner indoor unit 20 to operate in cooling mode, and adjusting the heat exchanger 23 to the air flow path where the first air inlet 211 is located;

[0154] Step S621, calculating the temperature difference between the second temperature and the first temperature;

[0155] Step S622, determining whether the temperature difference between the second temperature and the first temperature is greater than or equal to the first preset temperature value; if so, proceeding to step S631'; if not, proceeding to step S633';

[0156] Step S633 ′: control the air-conditioning indoor unit 20 to operate in the heating mode, and adjust the heat exchanger 23 to the air flow path where the first air inlet 211 is located.

[0157] When the air-conditioning indoor unit 20 is in heating mode or cooling mode, the air duct regulating mechanism 22 is in its first state, the first air inlet 211 is open, and the second air inlet 212 is blocked. At this time, the heat exchanger 23 moves to the air flow path where the first air inlet 211 is located, so as to fully contact the air flow entering the casing 21 from the first air inlet 211, thereby allowing this part of the air flow to fully exchange heat with the heat exchanger 23, thereby improving the air conditioning effect of the air-conditioning room 1 when the air duct regulating mechanism 22 is in its first state.

[0158] When the air conditioner indoor unit 20 is in natural air supply mode and the air path adjustment mechanism 22 is in its second state, the first air inlet 211 is blocked and the second air inlet 212 is open. At this time, the heat exchanger 23 moves into the airflow path where the second air inlet 212 is located, allowing for full contact with the airflow entering the housing 21 from the second air inlet 212. Although the compressor of the air conditioner indoor unit 20 is not running, the heat exchanger 23 may still have a certain amount of residual heat or residual cooling. Therefore, moving the heat exchanger 23 into the airflow path where the second air inlet 212 is located can fully utilize this residual heat or residual cooling. Furthermore, the heat exchanger 23 can also filter and purify the airflow entering the housing 21 from the second air inlet 212 to a certain extent, thereby improving the cleanliness of the airflow entering the accommodating space 11.

[0159] Preferably, the air duct regulating mechanism 22 and the heat exchanger 23 can be driven by the same driving device 25 so that the two rotate synchronously around the same rotation axis.

[0160] In some embodiments, the at least one air outlet includes a first air outlet 213 disposed opposite to the first air inlet 211 , and a second air outlet 214 disposed opposite to the second air inlet 212 .

[0161] Furthermore, the air duct regulating mechanism 22 is configured to open the first air outlet 213 and block the second air outlet 214 in a first state, and to open the second air outlet 214 and block the first air outlet 213 in a second state. That is, when the air duct regulating mechanism 22 is in the first state, the first air inlet 211 and the first air outlet 213 are opened, and the second air inlet 212 and the second air outlet 214 are blocked. Air within the accommodating space 11 enters the casing 21 through the first air inlet 211 and flows out of the casing 21 through the first air outlet 213. When the air duct regulating mechanism 22 is in the second state, the first air inlet 211 and the first air outlet 213 are blocked, and the second air inlet 212 and the second air outlet 214 are opened. Air within the indoor space of the air-conditioned room 1 enters the casing 21 through the second air inlet 212 and flows out of the casing 21 through the second air outlet 214. Since the first air inlet 211 and the first air outlet 213 are arranged relative to each other, and the second air inlet 212 and the second air outlet 214 are arranged relative to each other, no matter whether the air path adjustment mechanism 22 is in the first state or the second state, it can ensure that the airflow in the casing 21 flows straight without changing the flow direction, thereby reducing the airflow resistance and increasing the airflow speed.

[0162] In some embodiments, the housing 21 is cylindrical, and the first air inlet 211, the second air inlet 212, the first air outlet 213, and the second air outlet 214 are all provided on the sidewall of the cylinder and spaced apart along the circumference of the cylinder. That is, the first air inlet 211, the second air inlet 212, the first air outlet 213, and the second air outlet 214 are all arc-shaped air outlets centered at the center of the cylinder.

[0163] Furthermore, the air path regulating mechanism 22 includes two curved baffles 221 that conform to the shape of the cylindrical sidewalls. These two curved baffles 221 respectively block the second air inlet 212 and the second air outlet 214 when the air path regulating mechanism 22 is in its first state, and respectively block the first air inlet 211 and the first air outlet 213 when the air path regulating mechanism 22 is in its second state. This effectively prevents air in the flow path between the first air inlet 211 and the first air outlet 213 from flowing out of the housing 21 through the second air inlet 212 and the second air outlet 214, and also effectively prevents air in the flow path between the second air inlet 212 and the second air outlet 214 from flowing out of the housing 21 through the first air inlet 211 and the first air outlet 213. This ensures a consistent airflow in all situations and enhances the air quality within the accommodating space 11.

[0164] Because both the air duct regulating mechanism 22 and the heat exchanger 23 are rotatable, their rotational paths are circular or arc-shaped. To this end, the present invention configures the housing 21 as a cylinder, with the first and second air inlets 211, 212, and the air outlet all located on the sidewalls of the cylinder. This ensures that the air duct regulating mechanism 22 maintains a good shielding relationship with the first and second air inlets 211, 212 after rotation. Furthermore, while ensuring smooth rotation of the air duct regulating mechanism 22 and the heat exchanger 23, the cylindrical housing 21 maximizes space utilization, minimizing space occupied within the housing, resulting in a highly ingenious design.

[0165] In some embodiments, the second air inlet 212 is opposite to and spaced from the ventilation inlet 12 to form a buffer space 13 between the second air inlet 212 and the ventilation inlet 12. The buffer space 13 is isolated from the accommodating space 11 by a sealing plate 14 on all sides except the side where the second air inlet 212 and the ventilation inlet 12 are located.

[0166] The sealing plate 14 effectively separates the ventilation inlet 12 from other areas of the accommodating space 11 except the buffer space 13 and the second air inlet 212 , so that the external air entering from the ventilation inlet 12 can only flow into the buffer space 13 and then into the second air inlet 212 .

[0167] On the one hand, the buffer space 13 provides a flow buffer for the air flowing into the air-conditioned room 1 from the ventilation inlet 12, reducing the resistance encountered by the air flowing into the air-conditioned room 1 from the ventilation inlet 12, thereby increasing the air intake of the ventilation inlet 12. On the other hand, the buffer space 13 also provides a certain distance buffer, increasing the distance between the second air inlet 212 and the ventilation inlet 12, thereby preventing the problem of heat or cold in the air-conditioning indoor unit 20 being easily lost to the outside of the air-conditioned room 1 due to the close distance between the second air inlet 212 and the ventilation inlet 12. In addition, the buffer space 13 also provides a certain visual buffer, preventing users from directly looking at the air-conditioning indoor unit 20 through the ventilation inlet 12, thereby improving the aesthetic appearance of the air-conditioned room 1.

[0168] In some embodiments, a functional module mounting seat 16 is provided on the inner side of the ventilation outlet 15. The air-conditioning room 1 further includes at least one functional module 17 disposed in the functional module mounting seat 16. The projection of each functional module 17 in the plane where the ventilation outlet 15 is located covers the ventilation outlet 15, so that the air is functionally processed by the at least one functional module 16 when the air flows through the ventilation outlet 15.

[0169] Specifically, the at least one functional module 17 may include, for example, a humidification module, a dehumidification module, a filtration module, a purification module, a sterilization module, an aromatherapy module, and the like.

[0170] The present invention also provides an air-conditioning room for plants. Figure 13 1 is a schematic structural block diagram of an air-conditioning room according to an embodiment of the present invention. The air-conditioning room 1 includes a housing 10, a first oxygen concentration detection device 61, a second oxygen concentration detection device 62 and a control device 90.

[0171] The housing 10 defines an accommodating space 11 for accommodating plants therein, and the housing 10 is provided with a ventilation outlet 15 , which is communicated with the first air-conditioning indoor unit 2 in the indoor space where the air-conditioning room 1 is located.

[0172] The first oxygen concentration detecting device 61 is used to obtain a first oxygen concentration in the accommodating space 11 .

[0173] The second oxygen concentration detection device 62 is used to obtain a second oxygen concentration in the indoor space where the air-conditioned room is located.

[0174] The control device 90 includes a processor 91 and a memory 92 . The memory 92 stores a machine executable program 93 . When the machine executable program 93 is executed by the processor 91 , it is used to implement the control method described in any of the above embodiments.

[0175] Specifically, the first oxygen concentration detection device 61 and the second oxygen concentration detection device 62 are both communicatively connected to the control device 90 .

[0176] Specifically, the processor 91 can be a central processing unit (CPU), a digital processing unit, or the like. The processor 91 sends and receives data via a communication interface. The memory 92 is used to store programs executed by the processor 91. The memory 92 is any medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, and can also be a combination of multiple memories. The above-mentioned machine-executable program 93 can be downloaded from a computer-readable storage medium to a corresponding computing / processing device or downloaded to a computer or external storage device via a network (e.g., the Internet, a local area network, a wide area network, and / or a wireless network).

[0177] Furthermore, the air-conditioned room 1 may further include a first temperature sensor 30 and a second temperature sensor 40. The first temperature sensor 30 is disposed within the housing 10 and is used to obtain a first temperature within the accommodating space 11. The second temperature sensor 40 is disposed outside the housing 10 and is used to obtain a second temperature within the indoor space where the air-conditioned room 1 is located.

[0178] Furthermore, the first temperature sensor 30 , the second temperature sensor 40 and the plant growth lamp 70 are all connected to the control device 90 .

[0179] The present invention further provides an air conditioning system 100 , which includes a first air conditioning indoor unit 2 and the air conditioning room 1 described in any one of the above embodiments.

[0180] The first air-conditioning indoor unit 2 is installed in an indoor space and is used to adjust the environment of the indoor space.

[0181] The air-conditioning room 1 is arranged in the indoor space where the first air-conditioning indoor unit 2 is located, and includes a shell 10 defining an accommodating space. The shell 10 is provided with a ventilation outlet 15 that is communicated with the first air-conditioning indoor unit 2 .
