Description

[0001] The present application relates to the technical field of building energy saving, in particular to a carbon emission regulation method for existing buildings. BACKGROUND

[0002] With the promotion of global carbon neutralization goal, the energy consumption and carbon emission of existing buildings are increasingly prominent. The energy consumption of systems such as air conditioning and lighting in building operation accounts for a high proportion, and factors such as outdoor environment changes and indoor personnel flows often lead to a mismatch between equipment operation and actual demand, exacerbating energy waste. Traditional regulation methods are difficult to dynamically adapt, and there is an urgent need for precise carbon emission control technology.

[0003] Traditional building equipment regulation relies on manual setting or single parameter control, and air conditioning systems often operate in a fixed mode without dynamically adjusting power in combination with outdoor temperature and indoor population density.

[0057] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be accurately conveyed to those skilled in the art. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0058] Referring to Figure 1 As shown in the drawings, in some embodiments of the present application, a carbon emission regulation method for an existing building comprises:

[0059] S1, real-time acquisition of outdoor temperature, indoor population density, indoor regional environmental temperature and indoor environmental brightness;

[0060] S2, adjusting the working state and power of the air conditioning system based on the outdoor temperature and the human comfort environment temperature range threshold.

[0061] S3, adjusting the power of the air conditioning system based on the working state and the indoor population density;

[0062] S4, adjusting the air sweeping direction and the wind speed of the direction of the air conditioning system based on the indoor area environment temperature and the human body comfortable environment temperature range threshold value;

[0063] S5, adjusting the power of the lighting system based on the indoor environment light brightness and the environment light brightness threshold value;

[0064] S6, adjusting the power of the air conditioning system and the lighting system based on the indoor environment light brightness and the outdoor temperature.

[0065] It can be understood that by acquiring the outdoor temperature, indoor population density, area environment temperature and environment light brightness and other parameters in real time, the working state, power, air sweeping direction and wind speed of the air conditioning system, and the power of the lighting system and the sunshade system are dynamically adjusted, realizing multi-factor linkage control. Both the human body comfortable environment temperature and light brightness requirements are guaranteed, and energy consumption is reduced through precise adjustment of equipment operation, thereby effectively reducing the carbon emissions of existing buildings and improving energy utilization efficiency.

[0066] In some embodiments of the present application, when the working state and power of the air conditioning system are controlled based on the outdoor temperature and the human body comfortable environment temperature range threshold value, it includes:

[0067] The preset outdoor temperature is T out , and the human body comfortable environment temperature range threshold value is [T com，min , T com,max ];

[0068] When T out ∈[T com，min , T com,max ], the air conditioning system stops working;

[0069] When T out >T com,max , the air conditioning system performs refrigeration work;

[0070] When T out <T com,min , the air conditioning system performs heating work.

[0071] Specifically, the human body comfortable environment temperature range threshold value is obtained by comprehensively considering the physiological response and subjective feeling of the human body through subjective evaluation, thermal comfort index calculation and thermal sensation prediction model and other means, and is the temperature range threshold value suitable for human life and work.

[0072] It can be understood that the specific rules for adjusting the working state and power of the air conditioning system based on the outdoor temperature and the human comfortable environment temperature range threshold are refined. By presetting the outdoor temperature and the human comfortable temperature range threshold, the judgment criteria for the air conditioner to stop working, cool or heat under different outdoor temperature conditions are determined, avoiding unnecessary operation of the air conditioner when the outdoor temperature is suitable, or energy waste due to ambiguous judgment when temperature adjustment is needed. This precise start-stop and mode switching based on the outdoor environment and human comfort demand can effectively reduce the invalid energy consumption of the air conditioner, ensure that the air conditioning system realizes reasonable use of energy from the initial stage on the premise of meeting the basic comfort demand, and reduce carbon emissions.

[0073] In some embodiments of the present application, when the air conditioning system is in cooling or heating work, comprising:

[0074] The original power of the air conditioning system is preset as W0, and the temperature difference corresponding to W0 is ΔT thre ;

[0075] When T out -T com,max > ΔT thre or T com.min -T out > ΔT thre , the power of the air conditioning system is adjusted to the first power;

[0076] When T out -T com,max = ΔT thre or T com.min -T out = ΔT thre , the power of the air conditioning system is kept as W0;

[0077] When T out -T com,max < ΔT thre or T com.min -T out < ΔT thre , the power of the air conditioning system is adjusted to the second power.

[0078] Specifically, the outdoor temperature corresponding to W0 is T0 The temperature difference corresponding to W0 is ΔT0

[0079] The first power calculation formula of the air conditioning system in cooling work is: The first power calculation formula of the air conditioning system in heating work is:

[0080] The second power calculation formula of the air conditioning system in cooling work is: The second power calculation formula of the air conditioning system when heating is working is:

[0081] It can be understood that the power adjustment rule of the air conditioner when cooling or heating is working is further refined, based on the preset original power and temperature difference range, the temperature difference is divided into different intervals, and is adjusted to the first power, the original power or the second power. This way of dynamically adjusting the power according to the temperature difference size avoids the excessive energy consumption caused by the air conditioner still running at a fixed power when the temperature difference is too large, and also prevents the waste caused by the power being too high when the temperature difference is small. By matching the power of the air conditioner with the actual temperature difference demand, the energy utilization efficiency can be significantly improved while ensuring the temperature adjustment effect, reducing unnecessary carbon emissions, and making the air conditioner run more economically and environmentally friendly.

[0082] In some embodiments of the present application, when adjusting the power of the air conditioning system based on the working state and the indoor population density, it includes:

[0083] When the air conditioning system is cooling:

[0084] The preset indoor population density is PD,W0 corresponds to the population density PD com ;

[0085] When PD=0, the air conditioning system stops working;

[0086] When PD=PD com , the power of the air conditioning system is kept as W0;

[0087] When PD com , the power of the air conditioning system is adjusted to the third power;

[0088] When PD>PD com , the power of the air conditioning system is adjusted to the fourth power;

[0089] When the air conditioning system is heating:

[0090] When PD=0, the air conditioning system stops working;

[0091] When PD=PD com , the power of the air conditioning system is kept as W0;

[0092] When PD com , the power of the air conditioning system is adjusted to the fourth power;

[0093] When PD>PD com , the power of the air conditioning system is adjusted to the third power.

[0094] Specifically, the third power calculation formula of the air conditioning system when cooling is working is: The third power calculation formula of the air conditioning system when heating is:

[0095]

[0096] The fourth power calculation formula of the air conditioning system when cooling is: The fourth power calculation formula of the air conditioning system when heating is:

[0097] It can be understood that, for different working states (cooling or heating), the air conditioning power is adjusted twice in combination with the indoor population density, and the population density threshold and the corresponding power adjustment scheme are preset. In the cooling and heating modes, rules of stopping working, keeping power, and adjusting to the third or fourth power are formulated according to the changes of the population density, which fully considers the differences in heat dissipation or heat production demand under different population densities. For example, the power is appropriately increased when the population is dense to meet the comfort demand of many people, and the power is reduced or stopped when the population is sparse, avoiding energy waste caused by mismatch between population change and air conditioning power, making the air conditioning operation more suitable for actual use scenarios, further optimizing energy consumption, and reducing carbon emissions.

[0098] In some embodiments of the present application, when adjusting the air conditioning system's air sweeping direction and air speed based on the indoor area environment temperature and the human comfort environment temperature range threshold, it includes:

[0099] The preset environment temperature of a certain area in the room is T around ;

[0100] When the air conditioning system is cooling:

[0101] If T around > T com,max , the air conditioning system's air sweeping direction is adjusted to the first air sweeping direction, and the air speed is adjusted to the first air speed;

[0102] If T around < T com,min , the air conditioning system's air sweeping direction is adjusted to the second air sweeping direction, and the air speed is adjusted to the second air speed;

[0103] If T around ∈ [T com，min , T com,max ], the air sweeping direction and air speed of other areas are adjusted;

[0104] If T around ∈ [T com，min , T com,max ] for all areas, the current air sweeping direction and air speed remain unchanged;

[0105] When the air conditioning system is heating:

[0106] If T around > T com,max , the air conditioning system is adjusted to a third air sweeping direction and a third air speed.

[0107] If T around < T com,min , the air conditioning system is adjusted to a fourth air sweeping direction and a fourth air speed.

[0108] If T around ∈ [T com，min , T com,max ], the air sweeping direction and air speed of other areas are adjusted, and if T around ∈ [T com，min , T com,max ] of all areas, the current air sweeping direction and air speed are kept unchanged.

[0109] Specifically, when the air conditioning system is in cooling mode, if the indoor temperature T around > T com,max (the temperature of the area is higher than the upper limit of the human body comfort temperature), the first air sweeping direction is the direction of the area, and if there is no obstacle in front of the area, the air is directly blown to the area, and if there is an obstacle, the air is blown upwards to reach the area by reflection, and the calculation formula of the first air speed is: wherein V0 is the original air speed before adjustment; if T around < T com,min (the temperature of the area is lower than the lower limit of the human body comfort temperature), the second air sweeping direction is the direction towards other areas with higher temperature (i.e. avoiding direct blowing to the low-temperature area to avoid lower temperature), and the calculation formula of the second air speed is: wherein V0 is the original air speed before adjustment.

[0110] When the air conditioning system is in heating mode, if T around > T com,max (the temperature of the area is higher than the upper limit of the human body comfort temperature), the third air sweeping direction is the direction towards other areas with lower temperature (i.e. avoiding direct blowing to the high-temperature area to avoid higher temperature), and the calculation formula of the third air speed is: wherein V0 is the original air speed before adjustment; if T around < T com,min (the temperature of the area is lower than the lower limit of the human body comfort temperature), the fourth air sweeping direction is the direction of the area (e.g. directly blowing to the area if there is no obstacle in front of the area, and blowing downwards to reach the area by reflection if there is an obstacle), and the calculation formula of the fourth air speed is: wherein V0 is the original air speed before adjustment.

[0111] It can be understood that the air conditioning is adjusted according to the indoor area environment temperature and the human body comfort temperature range threshold. By presetting the indoor area temperature, different air sweeping direction and air speed adjustment rules are formulated for cooling and heating modes respectively, so as to ensure that the area with temperature deviating from the comfort range can be accurately regulated, and the area with suitable temperature can be kept stable. This kind of accurate regulation in different areas avoids the indiscriminate air supply of the air conditioner to the whole space, reduces the problem of excessive overall power caused by local temperature discomfort, quickly balances the indoor area temperature, improves the local comfort of human body, and reduces the energy consumption through the optimization of air supply mode, thereby reducing carbon emissions.

[0112] In some embodiments of the present application, when the power of the lighting system is adjusted based on the indoor environment brightness and the environment brightness threshold, it includes:

[0113] The preset indoor environment brightness is L room , and the environment brightness threshold is L thre .

[0114] When L room =L thre or PD=0 or L room >L thre , the lighting system stops working.

[0115] When L room <L thre , the power of the lighting system is adjusted to the fifth power.

[0116] Specifically, the environment brightness threshold is the most suitable brightness of human eye photosensitive determined by professional light sensing detection equipment, a large amount of human eye visual feedback data in different environments, statistical analysis means, and research results of human eye visual physiological characteristics.

[0117] The calculation formula of the fifth power is: Wherein, W ' is the original power of the lighting system, and L ' is the corresponding environment brightness of W ' .

[0118] It can be understood that the rule of adjusting the power of the lighting system based on the indoor ambient brightness and the ambient brightness threshold is defined, the brightness threshold is preset, and it is stipulated that the lighting system should stop working or be adjusted to the fifth power under different brightness conditions. This rule avoids the phenomenon that the lighting system still runs in the case of sufficient natural light (excessive brightness) or no need for lighting (such as no one), and also prevents the problem that the insufficient brightness affects the use when the lighting power is insufficient. By matching the lighting power with the actual brightness demand, the invalid energy consumption of the lighting system can be minimized, the carbon emissions generated by lighting can be reduced, and the comfort of the indoor light environment can be ensured.

[0119] In some embodiments of the present application, when the power of the air conditioning system and the lighting system is adjusted based on the indoor ambient brightness and the outdoor temperature, it comprises:

[0120] When T out > T com,max and L room > L thre , the sunshade system is opened.

[0121] When the sunshade system is opened, it comprises:

[0122] Based on the influence of the sunshade on light and heat, the power of the lighting system is adjusted to the sixth power, and the power of the air conditioning system is adjusted to the seventh power.

[0123] Specifically, the calculation formula of the sixth power is: Wherein, W ' is the original power of the lighting system, L ' is the corresponding ambient brightness of W ' , K light is the influence coefficient of the sunshade on light;

[0124] Opening the sunshade system will reduce the entry of outdoor strong light and reduce the amplitude of the indoor brightness exceeding the threshold, so on the basis of reducing the original power W ' by the brightness exceeding amplitude ratio, the outdoor temperature exceeding amplitude ratio and the influence coefficient of the sunshade on light (which specifically represents the weakening degree of the sunshade on light) are additionally combined for further reduction to adapt to the change of the light environment after the sunshade, and to avoid excessive reduction of the lighting power;

[0125] The calculation formula of the seventh power is: Wherein, K heat is the influence coefficient of the sunshade on heat;

[0126] Opening the sunshade system will reduce the entry of outdoor heat and reduce the air conditioning cooling load, so on the basis of increasing the original power W0 based on the outdoor temperature exceeding amplitude ratio, the outdoor temperature exceeding amplitude ratio and the influence coefficient of the sunshade on heat K heatDown-regulation to balance the cooling effect of the sunshade and avoid excessive consumption of air conditioning power.

[0127] It can be understood that the cooperative regulation rules of the air conditioning system and the lighting system based on the indoor ambient brightness and the outdoor temperature are supplemented, especially the opening of the sunshade system under certain brightness and outdoor temperature conditions and the corresponding adjustment of the lighting and air conditioning power. The use of the sunshade system can effectively reduce the entry of outdoor strong light and heat into the indoor, reduce the cooling or heating load of the air conditioner, and adjust the lighting power in combination with the influence of the sunshade on the light to avoid the situation of excessive opening of the lighting due to insufficient indoor light caused by the sunshade. This multi-system cooperative regulation mode realizes the linkage optimization of the air conditioning, lighting and sunshade systems, further improves the overall energy utilization efficiency, and reduces the carbon emission of the existing building from multiple dimensions.
