Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, and more specifically, to a control method, device, air conditioning system, and storage medium for an air conditioning system. Background Technology

[0002] Train stations and bus stations are semi-enclosed spaces. Although waiting rooms and halls are relatively enclosed, the entrances and exits of passenger stations need to remain open to accommodate large passenger flows. Therefore, compared with fully enclosed spaces, passenger stations have the characteristic of exchanging energy with the outside world. However, compared with fully open spaces, passenger stations also have the characteristics of enclosed spaces, such as heat preservation and moisture retention. It can be seen that the environment in semi-enclosed spaces is more complex.

[0003] Specifically, given the characteristics of semi-enclosed spaces, they are prone to letting in dust or small insects from the outside. For example, a semi-enclosed space might be a bus stop. To reduce the occurrence of such situations and minimize the impact on people inside the bus stop, air curtain machines are often installed at the entrances and exits of the bus stop. These machines generate an air curtain at the entrances and exits to cover the semi-enclosed space, thereby reducing air exchange between the inside and outside of the semi-enclosed space and preventing the aforementioned dust or small insects from entering.

[0004] However, the relevant technologies have at least one of the following problems: after the air curtain airflow is discharged from the air curtain machine, the airflow generated by its impact on the ground is not fully utilized, and the operating functions of the air conditioner are not fully combined with the meteorological changes in the natural environment, resulting in low utilization of natural resources, low overall output efficiency, and high energy consumption. Summary of the Invention

[0005] The technical problem solved by this invention is that the airflow generated by the air curtain hitting the ground after being discharged from the air curtain machine is not fully utilized, and the operating functions of the air conditioner do not fully take into account the meteorological changes in the natural environment, resulting in low utilization of natural resources, low overall output efficiency, and high energy consumption.

[0006] To address the aforementioned problems, this invention provides a control method for an air conditioning system. The air conditioning system is installed in a semi-enclosed space, which includes a return air device, an air curtain machine, and an air conditioner. The air curtain machine is installed above the doorway of the semi-enclosed space to generate an air curtain airflow covering the doorway. The return air device is equipped with interconnected return air ducts and outlet air ducts. The control method includes: after controlling the air curtain machine and the return air device to start according to the natural time, predicting a first environmental parameter outside the semi-enclosed space within a first preset time period based on weather forecasting equipment, and determining whether the first environmental parameter meets the conditions for a sudden drop in temperature. If so, the operating function type of the air conditioner is determined based on the second environmental parameters within the semi-enclosed space; it is determined whether the parameter change information in the second environmental parameters meets the comfort conditions; if not, the state of the return air duct and the outlet air duct is adjusted according to the parameter change information; wherein, when the parameter change information includes temperature change information, the return air duct is controlled to be in the open state to receive the air curtain airflow and guide it into the semi-enclosed space; and / or, when the parameter change information includes carbon dioxide concentration change information, the outlet air duct is controlled to be in the open state to guide the air curtain airflow to the outside of the semi-enclosed space.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: Firstly, by installing a return air device in the semi-enclosed space, the airflow output by the air curtain machine is rationally utilized, reducing the airflow waste caused by the airflow hitting the ground. For example, the return air inlet of the return air duct can be located on the ground opposite the doorway, so that the residual airflow formed after the airflow hits the ground is guided into the return air duct through the return air inlet, and then reintroduced into the semi-enclosed space through the return air outlet of the return air duct. Furthermore, by utilizing the return airflow, the airflow velocity in this area is disturbed to a certain extent, further improving the diffusion efficiency of the cooling airflow in the semi-enclosed space when the air conditioner is operating in cooling mode, so that the temperature inside can be kept as uniform as possible. Secondly, considering actual weather conditions, when the first environmental parameter detected by meteorological forecasting equipment changes abruptly, it often leads to abrupt changes in the outdoor temperature (outside the semi-enclosed space), especially during summer rain, wind, or seasonal changes. Therefore, in response to the weather changes, the outdoor temperature is often close to the indoor temperature (in a semi-enclosed space). That is, the temperature outside the semi-enclosed space is close to the preset cooling temperature inside the semi-enclosed space. If the air conditioner is still running in cooling mode at this time, it will lead to unnecessary power consumption. Therefore, by combining the first environmental parameters under the sudden weather change, the operating state of the air conditioner can be temporarily adjusted, that is, the cooling function is adjusted to the fresh air function, so that the cooler outdoor airflow is used to replace the cooling airflow, so as to achieve a cooling effect in the semi-enclosed space, while also taking into account the fresh air effect. It can be understood that the air conditioner saves energy by running the fresh air function compared to running the cooling function.

[0008] In one embodiment of the present invention, determining the operating function type of the air conditioner based on a second environmental parameter within a semi-enclosed space includes: when the second temperature in the second environmental parameter is less than a preset temperature and greater than the first temperature in the first environmental parameter, the operating function type is determined to be a fresh air function; when the second temperature in the second environmental parameter is greater than the preset temperature and greater than the first temperature in the first environmental parameter, the operating function type is determined to include a fresh air function and / or a cooling function.

[0009] In one embodiment of the present invention, determining the operating function type includes a fresh air function and / or a cooling function, comprising: if the first temperature is less than a preset temperature, controlling the air conditioner to operate the fresh air function according to a preset air outlet setting; determining whether the temperature change rate of the second temperature meets a preset cooling rate within a second preset time period of operating the fresh air function and the cooling function; if not, controlling the air curtain machine to alternately perform a first operating action and a second operating action; wherein the first operating action includes generating an air curtain airflow at the doorway, and the second operating action includes canceling the air curtain airflow at the doorway; and / or, if the first temperature is greater than or equal to the preset temperature, controlling the air conditioner to operate the fresh air function and the cooling function simultaneously.

[0010] In one embodiment of the present invention, the air conditioner includes an indoor unit, which has a fresh air duct connecting the inside and outside of a semi-enclosed space. The fresh air duct includes a first fresh air inlet, a second fresh air inlet, and a third air outlet that are interconnected. A third control valve is provided at the position corresponding to the first fresh air inlet, and a fourth control valve is provided at the position corresponding to the second fresh air inlet. A filter assembly is provided at the position corresponding to the first fresh air inlet. When the air conditioner is controlled to operate the fresh air function, if the first environmental parameter includes non-rainy weather, it is determined whether to control the indoor unit to activate the filter function based on the obtained dust concentration outside the semi-enclosed space. If yes, the third control valve is controlled to open the first fresh air inlet, and the fourth control valve is controlled to close the second fresh air inlet. If no, the third control valve and the fourth control valve are controlled to open at least one of the first fresh air inlet and the second fresh air inlet that are respectively matched with them.

[0011] In one embodiment of the present invention, a semi-enclosed space is formed at a bus stop, and the bus stop is equipped with an automatic door assembly for closing or opening the semi-enclosed space. The system controls the activation of an air curtain and a return air device according to a natural time, including: when the natural time changes to the activation time, controlling the automatic door assembly to open the semi-enclosed space; controlling the air curtain to open, and controlling the return air duct and the outlet air duct to remain open simultaneously for a third preset time; when the natural time changes to the shutdown time, determining whether there is a thermal image corresponding to a preset human image within the semi-enclosed space; if so, controlling the automatic door assembly to play a warning message; if the target object corresponding to the thermal image is still within the semi-enclosed space within a fourth preset time, controlling the air curtain and the air conditioner to close, and delaying the closing time of the automatic door assembly; if there is no thermal image within the semi-enclosed space, controlling the air curtain and the air conditioner to close, and then controlling the automatic door assembly to close the semi-enclosed space.

[0012] In one embodiment of the present invention, determining whether the first environmental parameter meets the conditions for a sudden drop in temperature includes: if not, controlling the air conditioner to determine the operating function type based on the first environmental parameter and the second environmental parameter.

[0013] In one embodiment of the present invention, determining whether the parameter change information in the second environmental parameter meets the comfort conditions includes: if so, controlling the air conditioner to maintain its current operating function.

[0014] On the other hand, this invention also provides a control device for an air conditioning system. The air conditioning system is installed in a semi-enclosed space, and a return air device, an air curtain machine, and an air conditioner are provided in the semi-enclosed space. The air curtain machine is installed above the doorway of the semi-enclosed space to generate an air curtain airflow covering the doorway. The return air device is provided with an interconnected return air duct and an outlet air duct. The control device includes: a first judgment module, which is used to predict a first environmental parameter outside the semi-enclosed space within a first preset time according to a weather forecast device, and to determine whether the first environmental parameter meets the conditions for a sudden drop in temperature; and a control module, which is used to determine whether the semi-enclosed space meets the conditions for a sudden drop in temperature. The second environmental parameter within the room determines the operating function type of the air conditioner; the second judgment module is used to determine whether the parameter change information in the second environmental parameter meets the comfort conditions; the adjustment module is used to adjust the state of the return air duct and the outlet air duct according to the parameter change information; wherein, when the parameter change information includes temperature change information, the return air duct is controlled to be in the open state to receive the air curtain airflow and guide it to the semi-enclosed space; and / or, when the parameter change information includes carbon dioxide concentration change information, the outlet air duct is controlled to be in the open state to guide the air curtain airflow to the outside of the semi-enclosed space.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: it can achieve the technical effects corresponding to any of the control methods mentioned above, which will not be elaborated here.

[0016] In another aspect, the present invention also provides an air conditioning system, comprising: a processor and a memory, wherein the memory stores a computer program, and the processor executes the control method as described in any of the above examples when it invokes the computer program in the memory.

[0017] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: it can achieve the technical effects corresponding to any of the control methods mentioned above, which will not be elaborated here.

[0018] In another aspect, the present invention provides a storage medium for storing a computer program, which is loaded by a processor to execute a control method as described in any of the above examples.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: it can achieve the technical effects corresponding to any of the control methods mentioned above, which will not be elaborated here.

[0020] By adopting the technical solution of the present invention, the following technical effects can be achieved: (1) On the one hand, by setting up a return air device in the semi-enclosed space, the airflow output by the air curtain machine is rationally utilized, thereby reducing the airflow waste caused by the airflow hitting the ground. For example, the return air inlet of the return air duct can be located on the ground opposite the doorway, so that the residual airflow formed after the airflow hits the ground is introduced into the return air duct through the return air inlet, and then reintroduced into the semi-enclosed space through the return air outlet of the return air duct. Furthermore, by utilizing the return airflow, the airflow velocity in the area is disturbed to a certain extent, which further improves the diffusion efficiency of the cooling airflow in the semi-enclosed space when the air conditioner is operating in the cooling function, so that the temperature inside can be kept as uniform as possible; (2) On the other hand, considering the actual weather, when the first environmental parameter detected by the meteorological forecasting equipment changes suddenly, it often leads to a sudden change in the outdoor temperature (outside the semi-enclosed space), especially during summer rain, wind, or seasonal changes. Therefore, under the corresponding meteorological changes, the outdoor temperature is often close to the indoor temperature (inside the semi-enclosed space), that is, the temperature outside the semi-enclosed space is close to the preset cooling temperature inside the semi-enclosed space. If the air conditioner is still running the cooling function at this time, it will lead to an unnecessary increase in power consumption. Therefore, in combination with the first environmental parameter under the sudden weather change, the operating state of the air conditioner can be temporarily adjusted, that is, the cooling function can be adjusted to the fresh air function, so that the air with a lower outdoor temperature can replace the cooling air flow to achieve a cooling effect in the semi-enclosed space, while also taking into account the fresh air effect. It is understandable that the air conditioner saves energy when running the fresh air function compared to running the cooling function. Attached Figure Description

For example, the return air inlet of the return air duct can be located on the ground opposite the doorway, so that the residual airflow formed after the air curtain airflow hits the ground is guided into the return air duct through the return air inlet, and then reintroduced into the semi-enclosed space through the return air outlet of the return air duct. Furthermore, by utilizing the return airflow, the airflow velocity in this area is disturbed to a certain extent, further improving the diffusion efficiency of the cooling airflow in the semi-enclosed space when the air conditioner is operating in cooling mode, so that the temperature inside can be kept as uniform as possible. On the other hand, considering the actual weather, when the first environmental parameter detected by the meteorological forecasting equipment changes suddenly, it often leads to a sudden change in the outdoor temperature (outside the semi-enclosed space), especially during summer rain, wind, or seasonal changes. Therefore, in response to the weather changes, the outdoor temperature is often close to the indoor temperature (in a semi-enclosed space). That is, the temperature outside the semi-enclosed space is close to the preset cooling temperature inside the semi-enclosed space. If the air conditioner is still running in cooling mode at this time, it will lead to unnecessary power consumption.

It can be understood that the air conditioner saves energy by running the fresh air function compared to running the cooling function.

If so, control the third control valve to open the first fresh air inlet and control the fourth control valve to close the second fresh air inlet; If not, then control the third and fourth control valves to open at least one of the first and second fresh air inlets that are respectively matched with them.
