Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioning control method and an air conditioning system. Background Technology

[0002] As people's living standards continue to improve, their pursuit of a comfortable life is also increasing. When the outside environment is hot or cold, people always hope to quickly adjust to a more comfortable state when they return indoors from the outdoors.

[0003] However, in existing technologies, there is a lag in how people actively adjust their air conditioning settings; that is, people only adjust the air conditioning after they feel uncomfortable. Furthermore, the automatic adjustment of air conditioning systems lacks a mode for users transitioning from the outside environment to the air-conditioned environment. This means that even after entering an air-conditioned environment from the outdoors, it still takes a considerable amount of time for users to adjust to a comfortable state. Summary of the Invention

[0004] The purpose of this invention is to provide an air conditioning control method and an air conditioning system to solve the technical problem in the prior art that users still need a long time to adjust to a comfortable state after entering an air-conditioned environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] In a first aspect, the present invention provides an air conditioning control method, comprising:

[0007] S1. Select the air conditioning operating mode;

[0008] S2. When the intelligent operation mode is selected, obtain the climate parameter set;

[0009] S3. Based on the acquired climate parameter set, obtain the outdoor environmental parameter set G0, where G0 includes ambient temperature TO, ambient wind speed V0, and ambient humidity W0.

[0010] S4. Based on the obtained outdoor environmental parameter group G0, calculate the air conditioning intelligent operation parameter group G.

[0011] S5. Control the air conditioner to operate within the calculated intelligent operating parameter group G; where G includes the operating temperature within T and the operating humidity within W.

[0012] Furthermore, the set of climate parameters includes:

[0013] Local weather parameter group G1; and

[0014] External environmental parameter group G2; where G1 includes weather temperature T1, weather wind speed V1 and weather humidity W1, and G2 includes external temperature T2, external wind speed V2 and external humidity W2.

[0015] Furthermore, the outdoor environmental parameter group G0 is calculated using the following formula:

[0016] G0 = 0.85 * G1 + 1.15 * G2.

[0017] Furthermore, before calculating the intelligent operating parameter group G of the air conditioner, the following steps are also included:

[0018] Determine whether the outdoor environmental parameter group G0 is within the non-extreme environmental parameter group S;

[0019] When the judgment result is within the non-extreme environment parameter group S, calculate the air conditioning intelligent operation parameter group G.

[0020] If the judgment result is that the environment is not within the non-extreme environment parameter group S, then extreme environment control operations are performed.

[0021] Furthermore, the execution of extreme environment control operations includes:

[0022] When the ambient wind speed V0 in the outdoor environmental parameter group G0 is ≥ 0.5*V, the fresh air module stops working and the air conditioner starts.

[0023] When the ambient wind speed V0 in the outdoor environmental parameter group G0 is greater than V, the air conditioner will stop working, where V is the preset wind speed value.

[0024] Furthermore, the intelligent operating parameter group G of the air conditioner is calculated according to the following formula:

[0025] When the ambient temperature T0 in the outdoor environmental parameter group G0 is ≥21℃, T_internal = 0.8*T0-1, 30% ≤ W_internal ≤ 60%, where T_internal should be within the range of 16-28℃;

[0026] When the ambient temperature T0 in the outdoor environmental parameter group G0 is less than 21℃, T_internal = 0.5*T0 + 16, 30% ≤ W_internal ≤ 80%, where T_internal should be within the range of 18-26℃.

[0027] Furthermore, after the air conditioner runs for a first set time t1 within the calculated intelligent operating parameter group G, it repeats step S2 to re-acquire the climate parameter group and perform cyclic calculations.

[0028] Furthermore, the first set time t1 is 60 minutes.

[0029] Furthermore, after obtaining the outdoor environmental parameter set G0 based on the acquired climate parameter set, the timing t=0 is started. When the accumulated timing t reaches the second set time, the perceived temperature Tg0 is calculated according to the outdoor environmental parameter set G0. Based on the calculated perceived temperature Tg0, subsequent adjustment operations are performed.

[0030] Furthermore, the second set time is 10 minutes.

[0031] Furthermore, based on the calculated perceived temperature Tg0, subsequent adjustment operations are performed, including:

[0032] Determine whether the calculated perceived temperature Tg0 is within the preset perceived temperature Tg range;

[0033] When the calculated perceived temperature Tg0 is within the preset perceived temperature Tg range, the air conditioner is controlled to operate according to the calculated intelligent operating parameter group G.

[0034] When the calculated perceived temperature Tg0 is outside the preset perceived temperature Tg range, the real-time human body detection module is activated to detect people entering the room from the outside.

[0035] Based on the detection results from the real-time human detection module, further control operations are performed.

[0036] Furthermore, based on the detection results from the real-time human detection module, further control operations are performed, including:

[0037] When a human body is detected entering the indoor environment from the outside, the air conditioner is controlled to blow air onto the human body at a low speed. The air blowing includes fresh air as well as cold or hot air, and the air blowing is intermittent for a third set time.

[0038] If no human body is detected entering the indoor environment from the outside, the human body detection process for entering the indoor environment from the outside is repeated.

[0039] Furthermore, the third set time is 30 seconds.

[0040] Furthermore, the control method also includes: a timed start control step performed after the air conditioner selects the intelligent operation mode and before acquiring the climate parameter group; or, a timed start control step performed after controlling the air conditioner to operate according to the calculated intelligent operation parameter group G.

[0041] Furthermore, the timed start control step includes:

[0042] Preset weekday information and daily arrival time;

[0043] Based on preset weekday information and daily arrival time, the air conditioner is activated 15 minutes before arrival.

[0044] Furthermore, when controlling the air conditioner to start 15 minutes before arrival, a start request message is also sent to the user. Based on the user's different responses to the request, the air conditioner is controlled to start or stop.

[0045] Furthermore, after the air conditioner is started via a timed start-up control step, if the human body detection module repeatedly detects for 30 minutes and still does not detect any human body entering the indoor environment from the outside, the air conditioner will be stopped.

[0046] The air conditioning control method provided by this invention allows the air conditioner to collect parameters such as temperature, humidity, outside wind speed, perceived temperature, and weather when the user selects the intelligent operation mode. It also detects the user's body surface temperature using infrared, radar waves, and door lock association methods, and determines whether the user has entered the air-conditioned environment from the outside. The air conditioner then blows air onto the detected user entering the air-conditioned environment at the lowest fan speed, mixing fresh and cool air, and blowing intermittently. For people with regular sleep patterns, a specific timer function is provided, which not only reduces the time required for the user to adjust their state but also improves the user experience and increases comfort.

[0047] Secondly, the present invention provides an air conditioning system that utilizes the air conditioning control method for intelligent control.

[0048] The air conditioning system provided by this invention has two operating modes: a classic mode and an intelligent mode. In classic mode, its operation is the same as that of existing air conditioners. In intelligent mode, it can automatically collect parameters such as temperature, humidity, outside wind speed, perceived temperature, and weather. Then, it calculates outdoor environmental parameters based on the collected parameters and indoor operating parameters based on the outdoor environmental parameters, controlling the air conditioner to operate in a state consistent with the external environment. This facilitates the user's rapid adaptation when entering the room from the outside. The system then detects the user's body surface temperature through infrared, radar waves, and door lock association, determining whether the user has entered the air-conditioned environment from the outside. The air conditioner blows air onto the detected user entering the air-conditioned environment at the lowest fan speed, mixing fresh and cool air, and blowing intermittently. For people with regular schedules, a specific timer function is provided, which not only reduces the time for the user to adjust but also improves the user experience and increases comfort. Attached Figure Description

[0049] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0050] Figure 1 This is a control mode diagram of the air conditioning system of the present invention;

[0051] Figure 2 This is a logic control diagram of one embodiment of the air conditioning control method of the present invention. Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0053] like Figure 2 As shown, the present invention provides an air conditioning control method, comprising:

[0054] S1. Select the air conditioning operating mode; such as... Figure 1 As shown, the air conditioner's operating modes include classic mode and smart mode. When the air conditioner is in classic mode, it only accepts user-initiated adjustments, meaning user-initiated adjustments are the primary method, or, based on user-initiated adjustments, minor adjustments are made to the temperature, which is the secondary method of automatic intelligent adjustment, i.e., the existing adjustment mode. When the air conditioner is in smart mode, automatic intelligent adjustment is the primary adjustment method, but user-initiated adjustment commands still have the highest priority.

[0055] S2. When the user selects the intelligent operation mode, obtain the climate parameter group;

[0056] The climate parameter set includes:

[0057] The air conditioner obtains local weather parameter group G1 through the network connection module, where G1 includes parameters such as weather temperature T1, weather wind speed V1, and weather humidity W1; and the air conditioner obtains external environmental parameter group G2 through its own environmental detection module, where G2 includes parameters such as external temperature T2, external wind speed V2, and external humidity W2.

[0058] S3. Based on the acquired climate parameter set, that is, based on the acquired local weather parameter set G1 and external environment parameter set G2, the outdoor environment parameter set G0 is obtained, where G0 includes parameters such as ambient temperature TO, ambient wind speed V0 and ambient humidity W0.

[0059] The outdoor environmental parameter group G0 is calculated using the following formula:

[0060] G0 = 0.85 * G1 + 1.15 * G2.

[0061] S31. Determine whether the outdoor environmental parameter group G0 is within the non-extreme environmental parameter group S; where the non-extreme environmental parameter group S is a preset parameter group.

[0062] When the judgment result is within the non-extreme environment parameter group S, i.e. G0∈S, the intelligent air conditioner intelligent operation parameter group G is calculated; the intelligent air conditioner adjusts according to the intelligent operation parameter group G.

[0063] When the judgment result is that it is not within the non-extreme environment parameter group S, that is, the parameter V0 in group G0 exceeds the preset range, then the extreme environment control operation is executed.

[0064] In this embodiment, extreme environment control operations are performed, including:

[0065] When the ambient wind speed V0 in the outdoor environmental parameter group G0 is ≥ 0.5*V, the fresh air module stops working and the air conditioner starts.

[0066] When the ambient wind speed V0 in the outdoor environmental parameter group G0 is greater than V, the air conditioner will stop working, where V is the preset wind speed value.

[0067] S4. Based on the obtained outdoor environmental parameter group G0, calculate the air conditioning intelligent operation parameter group G.

[0068] Specifically, the intelligent operation parameter group G of the air conditioner is calculated using the following formula:

[0069] When the ambient temperature T0 in the outdoor environmental parameter group G0 is ≥21℃, T_internal = 0.8*T0-1, 30% ≤ W_internal ≤ 60%, where T_internal should be within the range of 16-28℃;

[0070] When the ambient temperature T0 in the outdoor environmental parameter group G0 is less than 21℃, T_internal = 0.5*T0 + 16, 30% ≤ W_internal ≤ 80%, where T_internal should be within the range of 18-26℃.

[0071] S5. Control the air conditioner to operate within the calculated intelligent operating parameter group G; where G includes the operating temperature within T and the operating humidity within W.

[0072] Furthermore, after the air conditioner runs for a first set time t1 within the calculated intelligent operating parameter group G, step S2 is repeated to reacquire the climate parameter group and perform cyclic calculations.

[0073] Furthermore, the first set time t1 is 60 minutes.

[0074] Furthermore, as an optional embodiment of the present invention, after obtaining the outdoor environmental parameter set G0 based on the acquired climate parameter set, timing t=0 is started;

[0075] S6. When the accumulated time t reaches the second set time, that is, after the air conditioner has been working for a period of time, calculate the perceived temperature Tg0 according to the outdoor environmental parameter group G0; the second set time is 10 minutes.

[0076] Based on the calculated perceived temperature Tg0, subsequent adjustment operations are performed, including:

[0077] Determine whether the calculated perceived temperature Tg0 is within the preset perceived temperature Tg range; where the preset perceived temperature Tg is a parameter preset in advance;

[0078] When the calculated perceived temperature Tg0 is within the preset perceived temperature Tg range, the air conditioner is controlled to operate according to the calculated intelligent operating parameter group G.

[0079] When the calculated perceived temperature Tg0 is outside the preset perceived temperature Tg range, the real-time human body detection module is activated to detect people entering the room from the outside. Based on the detection results of the real-time human body detection module, further control operations are performed.

[0080] Furthermore, based on the detection results from the real-time human detection module, further control operations are performed, including:

[0081] When a human body is detected entering the indoor environment from the outside, the air conditioner is controlled to blow air onto the body at a low speed. The airflow includes fresh air as well as cold or hot air, and the airflow is intermittent for a third set time; further, the third set time is 30 seconds. It should be noted that in this embodiment, intermittent airflow means that the time the air blows on the user is intermittent. Specifically, it can be blowing and stopping intermittently, or it can be blowing air to other places. The intermittent time can be 3 seconds of blowing and 2 seconds of stopping, until the total time reaches 30 seconds. Of course, other intermittent time intervals can also be used. The specific values ​​here are only examples, and the present invention does not specifically limit these values.

[0082] In this embodiment, the real-time human body detection module uses radar waves as an example. If it detects "door open, high / low temperature, or person approaching," it blows air onto the target at the lowest wind speed, mixing fresh air with cold / hot air, intermittently for 30 seconds; after 30 seconds, it returns to the previous operating state. The significance of this module is that when a person feels the outside temperature is too hot or too cold, it blows moderately hot or cold air onto the detected user entering from the outside, reducing the stimulation the user experiences when entering an air-conditioned environment from a high-temperature / severe-cold environment, lowering the risk of discomfort, and reducing the adjustment time from discomfort to comfort.

[0083] If no human body is detected entering the indoor environment from the outside, the detection process for human bodies entering the room from the outside is repeated. If the air conditioning system has a special timing module, the air conditioning will stop operating after 30 minutes of repeated detection. If the air conditioning system does not have a special timing module, the detection process will continue to repeat indefinitely.

[0084] For people with regular work and rest schedules, such as office workers, whose commuting times are generally fixed, a timed start function is proposed for these users. Specifically, the control method also includes: after the air conditioner selects the smart operation mode and before obtaining the climate parameter group, relying on a special timed module to execute the timed start control steps; or, after controlling the air conditioner to run according to the calculated smart operation parameter group G, relying on a special timed module to execute the timed start control steps.

[0085] When an air conditioning system has a special timing module, there are two control scenarios. One is that the air conditioner does not start 15 minutes before the scheduled time. In this case, the following applies: Figure 2 The control logic shown is used for control. Another case is that the air conditioner is already turned on 15 minutes before the arrival time and is already in intelligent control. In this case, step S6 is executed directly (this case is not shown in the figure).

[0086] In this invention, the timed start control step includes:

[0087] Preset weekday information and daily arrival time; this step can be done automatically, with the air conditioner learning the user's air conditioning habits and automatically setting the time after a period of time; or it can be done manually, with the user setting the weekday and arrival time themselves.

[0088] When the air conditioner is not turned on 15 minutes before the arrival time, based on the preset weekday information and daily arrival time, the air conditioner is turned on 15 minutes before the arrival time of the weekday to adjust the indoor environment. At the same time as the air conditioner is turned on, a request to start or a reminder message is sent to the user. The air conditioner is turned on or off depending on the user's response to the request or reminder.

[0089] Specifically, if the user refuses the start request or cancels the reminder, the air conditioner will be stopped; if the user does not refuse the start request or chooses to continue running the air conditioner without processing the reminder, the air conditioner will be started, so that the user can enjoy a comfortable environment after returning home from get off work.

[0090] Furthermore, after the air conditioner is started by a timed start control step, if the human body detection module repeatedly detects for 30 minutes and still does not detect a human body entering the indoor environment from the outside, that is, if the air conditioner has been running for 30 minutes and still does not detect "door open, high / low temperature, or person approaching", the air conditioner will stop and issue a reminder to the user.

[0091] The air conditioning control method provided by this invention allows the air conditioner to collect parameters such as temperature, humidity, outside wind speed, perceived temperature, and weather when the user selects the intelligent operation mode. It also detects the user's body surface temperature using infrared, radar waves, and door lock association methods, and determines whether the user has entered the air-conditioned environment from the outside. The air conditioner then blows air onto the detected user entering the air-conditioned environment at the lowest fan speed, mixing fresh and cool air, and blowing intermittently. For people with regular sleep patterns, a specific timer function is provided, which not only reduces the time required for the user to adjust their state but also improves the user experience and increases comfort.

[0092] The present invention provides an air conditioning system that utilizes the above-described air conditioning control method for intelligent control.

[0093] Furthermore, the air conditioning system includes a special timing module, an intelligent adjustment module, and a human body detection module; the special timing module can realize special timing functions, the intelligent adjustment module includes a fresh air module, a humidity adjustment module, a cooling and heating module, an environmental parameter detection module, and a network connection module; it can realize temperature adjustment function, fresh air function, and humidity adjustment function; the environmental parameter detection module is used to detect parameters such as temperature, humidity, and wind speed.

[0094] The air conditioning system provided by this invention has two operating modes: a classic mode and an intelligent mode. In classic mode, its operation is the same as that of existing air conditioners. In intelligent mode, it can automatically collect parameters such as temperature, humidity, outside wind speed, perceived temperature, and weather. Then, it calculates outdoor environmental parameters based on the collected parameters and indoor operating parameters based on the outdoor environmental parameters, controlling the air conditioner to operate in a state consistent with the external environment. This facilitates the user's rapid adaptation when entering the room from the outside. The system then detects the user's body surface temperature through infrared, radar waves, and door lock association, determining whether the user has entered the air-conditioned environment from the outside. The air conditioner blows air onto the detected user entering the air-conditioned environment at the lowest fan speed, mixing fresh and cool air, and blowing intermittently. For people with regular schedules, a specific timer function is provided, which not only reduces the time for the user to adjust but also improves the user experience and increases comfort.

[0095] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
