Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning control, and in particular to a spatial energy storage control method, a controller and a medium for an air conditioning user end. Background Art

[0002] Air conditioning is a major energy consumer in buildings. Many buildings use the peak-valley electricity price difference of the power grid combined with energy storage technology to reduce air conditioning operating costs. Existing technologies include ice storage, water storage, phase change thermal storage, etc., but the cost is high and the system is complex. The specific heat capacity of air is much smaller than that of water and solid materials. Currently, the entire industry has not adopted related air energy storage technologies.

[0003] Generally speaking, the space served by indoor air conditioning is large and relatively closed. For example, in the summer cooling of an office, the air conditioner takes a long time to cool down after it is turned on, and generally it takes at least dozens of minutes to reach the set temperature. During this period, the people in the room need to endure the high temperature. Correspondingly, in the winter heating of an office, the air conditioner takes a long time to heat up after it is turned on, and generally it takes at least dozens of minutes to reach the set temperature. During this period, the people in the room need to endure the cold. Therefore, whether it is cooling in summer or heating in winter, the user's comfort is poor in the initial operation stage of the air conditioner.

[0004] Existing timing technology can be set to automatically turn on the air conditioner before work, but it cannot confirm whether there is actually someone in the room after work. If no one is at work, turning on the air conditioner in the morning will obviously cause meaningless waste of energy, especially for public institutions, where the number of people in each office is not fixed every day.

[0005] The inventors found that when offices are cooled in the summer, the cooling time is relatively long, but similarly, once the indoor temperature is lowered to a certain temperature and the air conditioner is turned off, the indoor temperature will continue to rise for dozens of minutes, especially when no one is in the room and the doors and windows are closed, the temperature recovery time will be longer. Correspondingly, when offices are heated in the winter, the heating time is relatively long, but similarly, once the indoor temperature is raised to a certain temperature and the air conditioner is turned off, the indoor temperature will continue to fall for a long time. Based on this, the present invention cleverly utilizes the energy storage of cooling or heating in the office when no one is there and in a relatively closed space, so that the indoor temperature can quickly reach the desired comfortable temperature after turning on the air conditioner at work. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a spatial energy storage control method, controller and medium for air-conditioning user ends, which utilizes the relatively closed space of the office when no one is around to store energy for cooling or heating. After turning on the air conditioner at work, the indoor temperature can quickly reach the required comfortable temperature, thereby improving the comfortable experience of indoor people using the air conditioner.

[0007] In a first aspect, a space energy storage control method for an air conditioner user end is provided, which is implemented by controlling the air conditioner pre-operation, and includes the following steps:

[0008] Set the target temperature during the air conditioning pre-operation period;

[0009] Set the air conditioner pre-operation time period;

[0010] Determine whether the triggering conditions for air conditioning pre-operation are met, that is, at the start time of air conditioning pre-operation, determine whether there is a manual air conditioning start instruction within the preset period before this time; if so, start the air conditioning pre-operation, and the air conditioning mode continues the air conditioning mode of the last air conditioning operation; if not, do not start the air conditioning pre-operation.

[0011] Furthermore, the setting of the target temperature during the pre-operation of the air conditioner includes:

[0012] Directly set the first target temperature of the air conditioner in the cooling mode and / or the second target temperature in the heating mode for pre-operation;

[0013] Alternatively, the setting of the target temperature during the pre-operation of the air conditioner includes:

[0014] The temperature deviation K1 is set. The first target temperature of the air conditioner in the cooling mode is the temperature set when the air conditioner was last run minus the temperature deviation K1. The second target temperature of the air conditioner in the heating mode is the temperature set when the air conditioner was last run plus the temperature deviation K1.

[0015] By setting the temperature deviation, the indoor temperature can be adjusted to be cooler or warmer, thereby extending the indoor heating or cooling time so that the indoor temperature is closer to the user's target temperature at work, improving user comfort.

[0016] Furthermore, the setting of the air conditioning pre-operation time period includes:

[0017] Directly set the shutdown time and startup time of the air conditioner pre-operation;

[0018] Alternatively, the setting of the air conditioning pre-operation time period includes:

[0019] Directly set the shutdown time of the air conditioner pre-operation, and adaptively adjust the startup time of the air conditioner pre-operation according to the heating and cooling speed of the indoor environment where the air conditioner is located based on the shutdown;

[0020] Alternatively, the setting of the air conditioning pre-operation time period includes:

[0021] The last manual start-up time of the air conditioner is delayed by 24-a hours as the start-up time of the air conditioner pre-operation, and the last manual start-up time of the air conditioner is delayed by 24-b hours as the shut-down time of the air conditioner pre-operation; 0<b<a<4.

[0022] Further, the shutdown time directly set for the pre - operation of the air conditioner is the manual startup time of the air conditioner on the previous day minus the preset advance duration parameter K0.

[0023] Further, the method for adaptively adjusting the startup time of the air conditioner pre - operation based on the shutdown according to the indoor temperature rise and fall speed where the air conditioner is located specifically includes:

[0024] Step1: Set the initial value of the estimated duration parameter K4;

[0025] Step2: The startup time of the air conditioner pre - operation is the shutdown time of the air conditioner pre - operation minus the estimated duration parameter K4;

[0026] Step3: Statistically calculate the duration K5 from the startup time of the air conditioner pre - operation to when the indoor temperature reaches the target temperature. If K5 < K4, correct K4: K4 = K5; then return to Step2;

[0027] Step4: Collect the temperature when the air conditioner has been running for the duration K4 starting from the startup time of the air conditioner pre - operation. If the currently collected temperature does not reach the target temperature, extend K4: K4 = K4 + K6, where K6 is the preset correction duration; then return to Step2.

[0028] Because of the different indoor space sizes and different weather conditions, the time for indoor temperature reduction or increase will also be different. If the pre - operation duration of all air conditioners is unified and the indoor temperature is ensured to reach the specified temperature, it will cause waste. Therefore, by adaptively adjusting the startup time or the pre - operation time period of the air conditioner pre - operation, that is, according to the feedback of indoor personnel, it can self - learn the inertia of the indoor air temperature, and can automatically correct the pre - operation time period under complex factors such as different air temperatures and different room sizes, which can avoid waste of resources.

[0029] Further, the pre - operation time period of the air conditioner is located in the low - valley period of the power grid electricity price. Setting the pre - operation time period of the air conditioner in the low - valley period of the power grid electricity price can effectively reduce the electricity cost expenditure.

[0030] Further, only on the dates within the set working date table, judge whether the trigger condition for the air conditioner pre - operation is satisfied.

[0031] Further, it further includes:

[0032] During the pre - operation of the air conditioner, if a manual operation instruction is received, the air conditioner automatically exits the pre - operation.

[0033] In a second aspect, a controller is provided, which is communicatively connected to the air conditioner, and the controller is configured to execute the space energy storage control method for the air - conditioner user side as described above.

[0034] According to a third aspect, an air conditioner is provided, wherein the air conditioner is configured to execute the spatial energy storage control method for the air conditioner user end as described above.

[0035] In a fourth aspect, a computer-readable storage medium is provided, on which a computer program or instruction is stored. When the computer program or instruction is executed by a processor, the spatial energy storage control method for the air-conditioning user end as described above is implemented.

[0036] The present invention proposes a space energy storage control method, controller and medium for air conditioner user end, which has the following beneficial effects compared with the prior art:

[0037] (1) Existing air conditioning energy storage technologies include ice storage, water storage, phase change storage, etc. The system is complex and can only be used for the cold and heat energy supply side of the central air conditioning system, that is, the machine room end of the central air conditioning. It is obviously not applicable to thousands of air conditioning terminals scattered in various corners of the building. The present invention cleverly uses the office when no one is there and the relatively closed space to store cold or warm air. After turning on the air conditioner at work, the indoor temperature can quickly reach the required comfortable temperature, allowing the indoor air to change from a pure air conditioning cold and hot consumption end to an air conditioning cold and hot energy storage end at zero cost. It is both a supply end and a consumption end, and the two can achieve seamless conversion, which completely subverts the pattern of the traditional air conditioning system; although the amount of air energy storage in a single office is limited, it is of great significance to many buildings with hundreds or thousands of rooms in the city.

[0038] (2) Traditional simple scheduled startup and shutdown cannot be used in the air conditioning pre-operation mode. Even if the set timing parameters just meet the temperature requirements of the air conditioning pre-operation, for public buildings such as office buildings, not every room must have people entering the room to work and use the air conditioner every day. Once no one enters the room during the day for several days or even weeks, the air conditioning pre-operation every morning will cause a lot of waste. The present invention combines equipment timing management, that is, the self-timing management of the air conditioning machine, with human behavior for interaction. When executing the air conditioning pre-operation, it is necessary to detect whether someone has used the air conditioner within the previous preset time period (such as 24 hours). If no one operates the air conditioner through the air conditioning controller, the air conditioning pre-operation is automatically canceled, completely eliminating the situation where no one is in the room and the air conditioner automatically turns on in the morning. Therefore, the present invention adopts a human-computer interactive management mode, which is incomparable to the traditional timing method. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0040] Figure 1 This is a flow chart of a space energy storage control method for an air conditioner user terminal provided by an embodiment of the present invention;

[0041] Figure 2 The invention provides a method for adaptively adjusting the start-up time of an air conditioner in pre-operation. DETAILED DESCRIPTION

[0042] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a space energy storage control method for an air conditioner user end, which is implemented by controlling the pre-operation of the air conditioner, and includes the following steps:

[0044] S1: Set the target temperature during the air conditioning pre-operation period;

[0045] S2: Set the air conditioner pre-operation time period;

[0046] S3: Determine whether the triggering condition for air conditioning pre-operation is met, that is, at the start time of air conditioning pre-operation, determine whether there is a manual air conditioning start instruction within a preset period before this time; if so, start the air conditioning pre-operation, and the air conditioning mode continues the air conditioning mode of the last air conditioning operation; if not, do not start the air conditioning pre-operation.

[0047] It should be noted that the order of step S1 and step S2 can be interchanged, and the step execution order given here is only one embodiment of the present invention.

[0048] The above embodiment provides a space energy storage control method for air conditioner user terminals, which has the following beneficial effects compared with the prior art:

[0049] (1) Existing air conditioning energy storage technologies include ice storage, water storage, phase change storage, etc. The system is complex and can only be used for the cold and heat energy supply side of the central air conditioning system, that is, the machine room end of the central air conditioning. It is obviously not applicable to thousands of air conditioning terminals scattered in various corners of the building. The present invention cleverly uses the office when no one is there and the relatively closed space to store cold or warm air. After turning on the air conditioner at work, the indoor temperature can quickly reach the required comfortable temperature, allowing the indoor air to change from a pure air conditioning cold and hot consumption end to an air conditioning cold and hot energy storage end at zero cost. It is both a supply end and a consumption end, and the two can achieve seamless conversion, which completely subverts the pattern of the traditional air conditioning system; although the amount of air energy storage in a single office is limited, it is of great significance to many buildings with hundreds or thousands of rooms in the city.

[0050] (2) Traditional simple scheduled startup and shutdown cannot be used in the air conditioning pre-operation mode. Even if the set timing parameters just meet the temperature requirements of the air conditioning pre-operation, for public buildings such as office buildings, not every room must have someone enter the room to work and use the air conditioner every day. Once no one enters the room during the day for several days or even weeks, the air conditioning pre-operation every morning will cause a lot of waste. The present invention combines the equipment timing management, that is, the self-timing management of the air conditioning machine, with human behavior for interaction. When executing the air conditioning pre-operation, it is necessary to detect whether someone has used the air conditioner within the previous preset period (generally within 24 hours by default). If no one operates the air conditioner through the air conditioning controller, the air conditioning pre-operation is automatically cancelled, completely eliminating the situation where no one in the room automatically turns on in the morning. For example: if someone manually turned on the machine during work yesterday, the air conditioning started pre-operation the next morning; if no one went to work yesterday on Saturday, or it is not the air conditioning season now and the air conditioner does not need to be turned on, the air conditioning will not start pre-operation the next morning to avoid waste. Therefore, the present invention adopts a human-computer interactive management mode, which is incomparable to the traditional timing method.

[0051] In some embodiments, setting the target temperature during the pre-operation of the air conditioner includes:

[0052] The air conditioner is directly pre-operated to set a first target temperature in the cooling mode and / or a second target temperature in the heating mode.

[0053] The method of setting the target temperature is relatively simple and easy to implement, but it cannot be dynamically adjusted according to the temperature requirements of users at different times. Based on this, in some preferred embodiments of the present invention, the target temperature during the pre-operation of the air conditioner is set to include:

[0054] Set the temperature deviation K1. The first target temperature of the air conditioner in the cooling mode is the temperature set when the air conditioner was last run minus the temperature deviation K1. The second target temperature of the air conditioner in the heating mode is the temperature set when the air conditioner was last run plus the temperature deviation K1. The value range of the temperature deviation K1 is 2-8℃. Taking K1 as 5℃ as an example, in the cooling mode, if the temperature set when the air conditioner was last run was 26℃, the first target temperature is 26℃-5℃=21℃; in the heating mode, if the temperature set when the air conditioner was last run was 20℃, the second target temperature is 20℃+5℃=25℃.

[0055] By setting the temperature deviation, the indoor temperature can be adjusted to be cooler or warmer, thereby extending the indoor heating or cooling time so that the indoor temperature is closer to the user's target temperature at work, improving user comfort.

[0056] In some embodiments, setting the air conditioning pre-operation time period includes:

[0057] Directly set the start time and shut down time of the air conditioner pre-operation.

[0058] The setting method of the air conditioner pre-operation time period is relatively simple and easy to implement. However, due to the different sizes of indoor spaces and different weather conditions, the indoor cooling or heating time will also be different. When all air conditioners are pre-operated for a unified time, if the scheduled operation time is too long, the cold or heat storage time of the room air will be too long, which will cause waste; if the scheduled operation time period is too short, the room air storage cold or heat storage is insufficient, which is not conducive to quickly reaching the required temperature of the air conditioner after work. Based on this, in some preferred embodiments of the present invention, the setting of the air conditioner pre-operation time period includes:

[0059] Step 1: Set the shutdown time of the air conditioner pre-operation. In the specific implementation process, there are two ways to determine the shutdown time: one is to set a fixed value, such as setting a pre-operation shutdown hour parameter K2 (range 00-24, default 7), and a pre-operation shutdown minute parameter K3 (range 00-59, default 00), that is, the default value of the air conditioner pre-operation shutdown time is 7:00, and the time can be set by yourself in other embodiments; the second is to automatically adjust according to the manual start-up time of the air conditioner on the previous day. The specific shutdown time is the manual start-up time of the air conditioner on the previous day minus the preset advance time parameter K0. The value of K0 can be set by yourself and can be selected within the range of 20-80 minutes.

[0060] Step 2: Adaptively adjust the start-up time of the air conditioner according to the indoor temperature rise and fall speed of the air conditioner, such as Figure 2 As shown, the specific steps include:

[0061] Step 1: Set the initial value of the estimated duration parameter K4; in this embodiment, the range of K4 is 0 - 99, unit: minute. In this embodiment, the initial value of K4 is taken as 90 minutes;

[0062] Step 2: The start time of the air conditioner pre - operation is the shutdown time of the air conditioner pre - operation minus the estimated duration parameter K4. Therefore, in this embodiment, the start time of the first air conditioner pre - operation is 5:30;

[0063] Step 3: Detect the duration K5 (such as 40 minutes) from the start time of the air conditioner pre - operation to when the indoor temperature reaches the target temperature. At this time, K5 < K4, and correct K4: K4 = K5; then return to Step 2, and the start time of the next air conditioner pre - operation is 6:20; if the temperature does not reach the target temperature after the air conditioner pre - operation for K4 duration, then enter Step 4;

[0064] Step 4: Collect the temperature when the air conditioner has run for K4 duration starting from the start time of the air conditioner pre - operation. If the currently collected temperature does not reach the target temperature, then extend K4: K4 = K4 + K6, where K6 (such as 10 minutes) is the preset correction duration; then return to Step 2, and the start time of the next air conditioner pre - operation is 6:10. In a specific embodiment, the maximum value of K4 can be set to ensure that the air conditioner pre - operation duration does not exceed this maximum value.

[0065] This embodiment can self - learn the inertia of the indoor air temperature according to the feedback of indoor personnel, and can automatically correct the pre - operation time period under complex factors such as different air temperatures and different room sizes. It can avoid resource waste and ensure that the required temperature of the air conditioner is quickly reached after going to work, which cannot be achieved by the existing timing technology.

[0066] Considering that some low - cost air - conditioning devices do not have a clock chip, no time display and function, but the working time of the office every day is basically a 24 - hour cycle behavior. For example, going to work at 8 am this morning, and still going to work at 8 am tomorrow after 24 hours. Therefore, for the scenario where there is no clock chip in the air - conditioning device, the setting of the air conditioner pre - operation time period includes:

[0067] Delay the last manual startup time of the air conditioner by 24 - a hours as the start time of the air conditioner pre - operation, and delay the last manual startup time of the air conditioner by 24 - b hours as the shutdown time of the air conditioner pre - operation; 0 < b < a < 4.

[0068] The specific values of a and b can be selected according to actual needs. If it is necessary to end the pre - operation half an hour or an hour before going to work, the value of a can be taken as 0.5 or 1; if it is necessary to have a pre - operation duration of one hour or two hours, b is taken as 1 or 2. In the specific implementation process, generally b - a ≥ 0.5.

[0069] In a specific embodiment, the air conditioner pre-operation time period is preferably in the low-price period of the power grid. Setting the air conditioner pre-operation time period in the low-price period of the power grid can effectively reduce electricity cost.

[0070] In some embodiments, the judgment of whether the triggering condition of the air conditioner pre-operation is met is performed only on the date in the set working date table. Through this setting, the air conditioner pre-operation can be not started on the morning of Saturdays, Sundays and holidays to avoid waste.

[0071] In some embodiments, it also includes:

[0072] During the pre-operation of the air conditioner, if a manual operation instruction is received, the air conditioner will automatically exit the pre-operation.

[0073] An embodiment of the present invention further provides a controller which is communicatively connected to an air conditioner, and the controller is configured to execute the spatial energy storage control method for an air conditioner user end as described in the aforementioned embodiment.

[0074] Preferably, a pre-operation mode switch is provided in the controller and is turned on and activated so that the user can manually turn on or off the space energy storage control method for the air-conditioning user end.

[0075] It should be noted that the controller can be an air-conditioning controller, or a PC or mobile terminal connected to the air-conditioning network.
