Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building energy conservation, and more specifically, to a method, device, electronic device and storage medium for adjusting a thermal comfort neutral value. Background Art
[0002] The thermal comfort model, also known as the PMV (Predicted Mean Vote) index, is an experimental regression formula for the relationship between human thermal sensation and human heat load obtained by Danish researcher Van Gel after collecting a large amount of hot and cold sensation data from subjects in thermal comfort experiments conducted in artificial climate rooms with stable indoor parameters. The calculation results of this formula divide human thermal sensation into 7 levels, as shown in the following table:
[0003] PMV value +3 +2 +1 0 -1 -2 -3 Thermal sensation hot warm Slightly warm Moderate Slightly cool cold cold
[0004] With the continuous development of HVAC technology, more and more HVAC equipment manufacturers, system operators and scientific research institutes have incorporated the principles of thermal comfort models into system operation strategies, and adjusted system operation through the PMV index to achieve the purpose of cooling and heating comfort.
[0005] However, the application of PMV index in actual projects also has some problems: first, its thermal comfort neutral value is single, that is, PMV = 0. When other parameters (human metabolic rate, relative humidity, average radiation temperature, clothing thermal resistance and wind speed) are determined, the air temperature value that reaches the "moderate" thermal comfort state is a single value and cannot be adjusted. Secondly, although the national standard "GB 50736-2012 Civil Building Heating, Ventilation and Air Conditioning Design Code" gives relevant instructions in the clause explanation: "For the consideration of building energy conservation, the indoor environment of the heating condition is required to be cooler under the condition of comfort, and the cooling condition is required to be hotter under the condition of thermal comfort", as well as a specific thermal comfort level classification table. However, it only gives the PMV value range that meets the thermal comfort state under different thermal comfort levels, lacks specific adjustment methods, and is difficult to apply in actual projects. The above problems make the thermal comfort model ineffective in actual application, and the heating system cannot achieve the purpose of comfortable heating. Summary of the invention

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0064] Figure 1 This is a flow chart of a method for adjusting thermal comfort value according to an embodiment of the present application.
[0065] like Figure 1 The thermal comfort value adjustment method is applied to a heating system, specifically to an electronic device of the heating system, for providing a thermal comfort neutral value for a control system of the heating system. The electronic device can be understood as a computer, a server or an embedded device with data computing and information processing capabilities. The adjustment method specifically includes the following steps:
[0066] S1. Outdoor temperature value based on outdoor temperature sensor.
[0067] The concept of outdoor refers to the external environment of the place heated by the heating system. For example, for a building, the inside of the building is indoors, and the outside of the building is outdoors. When collecting the outdoor temperature value, the temperature is collected based on one or more temperature sensors arranged outdoors. The specific collection process is as follows:
[0068] First, obtain the outdoor temperature collected by the outdoor temperature sensor;
[0069] Then, if there is only one temperature sensor installed outdoors, the outdoor temperature can be used as the outdoor temperature value T 外 If there are multiple temperature sensors installed outdoors, the multiple outdoor temperatures are averaged and the average value is used as the outdoor temperature value T 外 , the specific calculation formula is as follows:
[0070]
[0071] Where n is the number of outdoor temperature sensors, T 外i is the outdoor temperature collected by the i-th temperature sensor.
[0072] S2. Calculate the indoor comfortable temperature value based on the functional relationship and constraint conditions.
[0073] That is, the outdoor temperature value is calculated based on the pre-built functional relationship and constraints to obtain the indoor comfortable temperature value T 内-舒适 .
[0074] Specifically, the functional relationship is:
[0075]
[0076] Among them, T 内-舒适 is the room temperature comfort temperature value under the corresponding winter outdoor temperature conditions, in degrees Celsius (℃); T 内-舒适下限 is the lower limit of comfortable temperature, in degrees Celsius; T 内-舒适上限 is the upper limit of comfortable temperature, in degrees Celsius; T 外 is the outdoor temperature value in degrees Celsius; T 外-上限 It is the upper limit of outdoor temperature, which can be set in degrees Celsius; T 外-下限 It is the lower limit of outdoor temperature, which can be set in degrees Celsius.
[0077] The constraints are:
[0078] T 内-舒适下限 ≤T 内-舒适 ≤T 内-舒适上限
[0079] Among them, T内-舒适上限 T is the upper limit of indoor temperature, which can be set in degrees Celsius; 内-舒适下限 It is the lower limit of indoor temperature, which can be set in degrees Celsius.
[0080] During winter heating, when the outdoor temperature is low, the temperature difference between indoor and outdoor is large, so the indoor and outdoor heat exchange is strong, and the indoor heat loss is large. At this time, the indoor temperature should be appropriately increased to achieve a comfortable state; similarly, when the outdoor temperature is high, the indoor and outdoor temperature difference is small, so the indoor and outdoor heat exchange is weak, and the indoor heat loss is small. At this time, the indoor temperature should be appropriately lowered to achieve the purpose of energy saving. Since the outdoor temperature fluctuates greatly during a complete heating season, in order to avoid the impact of special weather (outdoor temperature is too high or too low) on this adjustment scheme and ensure its integrity and efficiency, the upper and lower limits of the outdoor temperature can be set. When the outdoor temperature exceeds the upper limit, the indoor comfort temperature is set to the lower limit and no longer adjusted; when the outdoor temperature exceeds the lower limit, the indoor comfort temperature is set to the upper limit and no longer adjusted.
[0081] In summary, when T 外 Value in T 外-上限 With T 外-下限 Within the range, as T 外 The value gradually increases, T 内-舒适 The value will decrease dynamically; when T 外 Value exceeds T 外-下限 When the corresponding heating room comfort temperature is T 内-舒适 The value should be T 内-舒适上限 When T 外 Value exceeds T 外-上限 When the corresponding heating room comfort temperature is T 内-舒适 The value should be T 内-舒适下限 Therefore, the function of winter outdoor temperature and heating room comfort temperature should be a three-segment function. When the outdoor temperature is within the upper and lower limits, the function is a monotonically decreasing function; when the outdoor temperature exceeds the upper and lower limits, the function is a constant function.
[0082] S3. Calculate the thermal comfort neutral value based on the indoor comfort temperature value.
[0083] On the basis of obtaining the indoor comfortable temperature value, it is calculated based on the preset calculation formula to obtain the thermal comfort neutral value PMV. The specific calculation formula is as follows
[0084]
[0085] Where:
[0086] M is the metabolic rate, measured in watts per square meter (W / m 2 );
[0087] W is the effective mechanical power, measured in watts per square meter (W / m 2 );
[0088] I cl is the thermal resistance of clothing, in square meters Kelvin per watt (m 2 K / W);
[0089] f cl is the clothing surface area coefficient;
[0090] t a is the air temperature in degrees Celsius (℃);
[0091] is the mean radiation temperature in degrees Celsius (℃);
[0092] v ar is the relative wind speed in meters per second (m / s);
[0093] P a is the partial pressure of water vapor, in Pascals (Pa);
[0094] h c is the convective heat transfer coefficient, expressed in watts per square meter Kelvin [W / (m 2 ·K)];
[0095] t cl It is the surface temperature of the clothing in degrees Celsius (℃).
[0096] Simplify the PMV formula:
[0097] M is the metabolic rate of the human body;
[0098] W is the power of work done by the human body, which is generally zero;
[0099] P a is the partial pressure of water vapor, which can be calculated from the air temperature and relative humidity;
[0100] t a is the air temperature;
[0101] is the mean radiant temperature;
[0102] f cl is the clothing surface area coefficient and t cl The surface temperature of the clothing is I cl Function of thermal resistance of clothing;
[0103] h c is the convective heat transfer coefficient, is the wind speed v a Function of
[0104] The above parameters are all indoor parameters.
[0105] In summary, the PMV calculation formula can be simplified into a function with six variables: human metabolic rate, air temperature, relative humidity, average radiant temperature, clothing thermal resistance and wind speed as parameters. The PMV value of each room is calculated through the above six data values of each room, where the air temperature uses the comfortable temperature value of the heating room, and the calculated result is the thermal comfort neutral value of the heating room. On this basis, the thermal comfort neutral value is output to the corresponding control device so that the control device can control the heating system to achieve comfortable heating.
[0106] It can be seen from the above technical solution that this embodiment provides a method for adjusting a thermal comfort neutral value, which is applied to electronic equipment, specifically obtaining an outdoor temperature value based on at least one outdoor temperature sensor; processing the outdoor temperature value based on a pre-built functional relationship and constraint conditions to obtain an indoor comfort temperature value; and calculating based on the indoor comfort temperature value to obtain and output a thermal comfort neutral value, so that the control system of the heating system implements heating control based on the thermal comfort neutral value. Since the thermal comfort neutral value is generated based on the adjustment of multiple parameters, the heating system can achieve comfortable heating.
[0107] In addition, in a specific implementation of the present application, the following steps are also included: Figure 2 As shown:
[0108] S4. Repeat the calculation of the thermal comfort neutral value based on the set calculation frequency.
[0109] In view of the fact that the outdoor temperature and other parameters may change over time, in order to make the heating effect more comfortable, a calculation frequency can be set. The calculation frequency can be regarded as the cycle frequency of the above calculation process. At regular intervals, return to the above step S1, re-collect the outdoor temperature value, and then recalculate the thermal comfort neutral value based on the outdoor temperature value to make the real-time control of the heating system better.
[0110] This application is based on the above solution and provides the following specific embodiments for actual usage scenarios in Beijing.
[0111] The program to implement this adjustment method is built into the integrated energy management and control platform. The received telesignal and telemetry values are transmitted to the industrial gateway through the field equipment control cabinet by wired means, and then transmitted to the integrated energy management and control platform by the industrial gateway by wired or wireless means. After analysis and calculation by the integrated energy management and control platform, the control command is sent to the PLC or DCC control cabinet for control, or it can be directly sent to the local equipment for control.
[0112] This embodiment calculates the comfortable temperature value of the heating room of the commercial complex by the following formula:
[0113]
[0114] The constraints are as follows:
[0115] T 内-舒适下限 ≤T 内-舒适 ≤T 内-舒适上限
[0116] The function of winter outdoor temperature and comfortable temperature of heated room is a three-segment function. When the outdoor temperature is within the upper and lower limits, the function is a monotonically decreasing function; when the outdoor temperature exceeds the upper and lower limits, the function is a constant function.
[0117] In this embodiment, the outdoor temperature in winter is T 外 The range of values is based on the winter climate characteristics of Beijing:
[0118] -10℃≤T 外 ≤10℃
[0119] The upper and lower limits of the comfortable temperature of the heating room in this embodiment are based on the national standard "GB 50736-2012 Design Code for Heating, Ventilation and Air Conditioning in Civil Buildings", and the values are:
[0120] 18℃≤T 内-舒适 ≤24℃
[0121] In this embodiment, the monotonically decreasing segment of the three-segment function is selected as a linear function, from which the functional relationship can be obtained as follows (see Figure 3 ):
[0122]
[0123] In this embodiment, the method for selecting set values and constraints and the type of function selection are merely examples of the requirements of this patent, and other methods for selecting constraints and the type of function selection are within the scope of protection of this patent.
[0124] The commercial complex has three outdoor temperature sensors installed at different locations. Based on the outdoor temperature sensor data, T 外 value
[0125] The calculation formula is as follows:
[0126]
[0127] According to T 外 The comfortable temperature value T of the heating room in the commercial complex is calculated by using the above functional relationship. 内-舒适 .
[0128] The thermal comfort neutral value of each heating room in the commercial complex is calculated by calculating the comfortable temperature value of the heating room in the commercial complex.
[0129] The calculation formula is as follows:
[0130]

[0137] I cl Thermal resistance of clothing: Considering the comprehensive clothing of people in the heating season, combined with the provisions of the national standard "GB / T 18049-2017 Ergonomics of thermal environment - Analysis, measurement and interpretation of thermal comfort by calculating PMV and PPD index and local thermal comfort criteria", I is set cl The thermal resistance of clothing is 1.0cl o;
[0138] The PMV value of each room is calculated by the above six data values of each room, which is the thermal comfort neutral value of each heating room. The thermal comfort neutral value of each heating room is output to the corresponding control device.
[0139] This control method calculates the frequency by setting the delay time:
[0140] In this embodiment, the delay time is selected as 1 hour, that is, the thermal comfort neutral value of each heating room is calculated once every 1 hour.
[0141] When the delay is over, the adjustment method returns to the first step and repeats the calculation cycle.

[0146] Figure 4 This is a block diagram of a device for adjusting thermal comfort values according to an embodiment of the present application.
[0147] like Figure 4The thermal comfort value adjustment device shown is applied to a heating system, specifically to an electronic device of the heating system, for providing a thermal comfort neutral value for the control system of the heating system. The electronic device can be understood as a computer, server or embedded device with data computing and information processing capabilities. The adjustment device specifically includes a temperature acquisition module 10, an initial calculation module 20 and a calculation output module 30.
[0148] The temperature acquisition module is used to obtain the outdoor temperature value based on the outdoor temperature sensor.
[0149] The concept of outdoor refers to the external environment of the place heated by the heating system. For example, for a building, the inside of the building is indoors, and the outside of the building is outdoors. When collecting the outdoor temperature value, the temperature is collected based on one or more temperature sensors arranged outdoors. The specific collection process is as follows:
[0150] First, obtain the outdoor temperature collected by the outdoor temperature sensor;
[0151] Then, if there is only one temperature sensor installed outdoors, the outdoor temperature can be used as the outdoor temperature value T 外 If there are multiple temperature sensors installed outdoors, the multiple outdoor temperatures are averaged and the average value is used as the outdoor temperature value T 外 , the specific calculation formula is as follows:
[0152]
[0153] Where n is the number of outdoor temperature sensors, T 外i is the outdoor temperature collected by the i-th temperature sensor.
[0154] The initial calculation module is used to calculate the indoor comfort temperature value based on the functional relationship and constraint conditions.
[0155] That is, the outdoor temperature value is calculated based on the pre-built functional relationship and constraints to obtain the indoor comfortable temperature value T 内-舒适 .
[0156] Specifically, the functional relationship is:
[0157]
[0158] Among them, T 内-舒适 is the room temperature comfort temperature value under the corresponding winter outdoor temperature conditions, in degrees Celsius (℃); T 内-舒适下限 is the lower limit of comfortable temperature, in degrees Celsius; T 内-舒适上限 is the upper limit of comfortable temperature, in degrees Celsius; T 外is the outdoor temperature value in degrees Celsius; T 外-上限 It is the upper limit of outdoor temperature, which can be set in degrees Celsius; T 外-下限 It is the lower limit of outdoor temperature, which can be set in degrees Celsius.
[0159] The constraints are:
[0160] T 内-舒适下限 ≤T 内-舒适 ≤T 内-舒适上限
[0161] Among them, T 内-舒适上限 T is the upper limit of indoor temperature, which can be set in degrees Celsius; 内-舒适下限 It is the lower limit of indoor temperature, which can be set in degrees Celsius.
[0162] During winter heating, when the outdoor temperature is low, the temperature difference between indoor and outdoor is large, so the indoor and outdoor heat exchange is strong, and the indoor heat loss is large. At this time, the indoor temperature should be appropriately increased to achieve a comfortable state; similarly, when the outdoor temperature is high, the indoor and outdoor temperature difference is small, so the indoor and outdoor heat exchange is weak, and the indoor heat loss is small. At this time, the indoor temperature should be appropriately lowered to achieve the purpose of energy saving. Since the outdoor temperature fluctuates greatly during a complete heating season, in order to avoid the impact of special weather (outdoor temperature is too high or too low) on this adjustment scheme and ensure its integrity and efficiency, the upper and lower limits of the outdoor temperature can be set. When the outdoor temperature exceeds the upper limit, the indoor comfort temperature is set to the lower limit and no longer adjusted; when the outdoor temperature exceeds the lower limit, the indoor comfort temperature is set to the upper limit and no longer adjusted.
[0163] In summary, when T 外 Value in T 外-上限 With T 外-下限 Within the range, as T 外 The value gradually increases, T 内-舒适 The value will decrease dynamically; when T 外 Value exceeds T 外-下限 When the corresponding heating room comfort temperature is T 内-舒适 The value should be T 内-舒适上限 When T 外 Value exceeds T 外-上限 When the corresponding heating room comfort temperature is T 内-舒适 The value should be T 内-舒适下限 Therefore, the function of winter outdoor temperature and heating room comfort temperature should be a three-segment function. When the outdoor temperature is within the upper and lower limits, the function is a monotonically decreasing function; when the outdoor temperature exceeds the upper and lower limits, the function is a constant function.
[0164] The calculation output module is used to calculate the thermal comfort neutral value based on the indoor comfort temperature value.
[0165] On the basis of obtaining the indoor comfortable temperature value, it is calculated based on the preset calculation formula to obtain the thermal comfort neutral value PMV. The specific calculation formula is as follows
[0166]
[0167] Where:
[0168] M is the metabolic rate, measured in watts per square meter (W / m 2 );
[0169] W is the effective mechanical power, measured in watts per square meter (W / m 2 );
[0170] I cl is the thermal resistance of clothing, in square meters Kelvin per watt (m 2 K / W);
[0171] f cl is the clothing surface area coefficient;
[0172] t a is the air temperature in degrees Celsius (℃);
[0173] is the mean radiation temperature in degrees Celsius (℃);
[0174] v ar is the relative wind speed in meters per second (m / s);
[0175] P a is the partial pressure of water vapor, in Pascals (Pa);
[0176] h c is the convective heat transfer coefficient, expressed in watts per square meter Kelvin [W / (m 2 ·K)];
[0177] t cl It is the surface temperature of the clothing in degrees Celsius (℃).
[0178] Simplify the PMV formula:
[0179] M is the metabolic rate of the human body;
[0180] W is the power of work done by the human body, which is generally zero;
[0181] P a is the partial pressure of water vapor, which can be calculated from the air temperature and relative humidity;
[0182] t a is the air temperature;
[0183] is the mean radiant temperature;
[0184] f cl is the clothing surface area coefficient and t cl The surface temperature of the clothing is I cl Function of thermal resistance of clothing;
[0185] h c is the convective heat transfer coefficient, is the wind speed v a Function of
[0186] The above parameters are all indoor parameters.
[0187] In summary, the PMV calculation formula can be simplified into a function with six variables: human metabolic rate, air temperature, relative humidity, average radiant temperature, clothing thermal resistance and wind speed as parameters. The PMV value of each room is calculated through the above six data values of each room, where the air temperature uses the comfortable temperature value of the heating room, and the calculated result is the thermal comfort neutral value of the heating room. On this basis, the thermal comfort neutral value is output to the corresponding control device so that the control device can control the heating system to achieve comfortable heating.
[0188] It can be seen from the above technical solution that this embodiment provides a device for adjusting a thermal comfort neutral value, which is applied to electronic equipment, specifically obtaining an outdoor temperature value based on at least one outdoor temperature sensor; processing the outdoor temperature value based on a pre-constructed functional relationship and constraint conditions to obtain an indoor comfort temperature value; and calculating based on the indoor comfort temperature value to obtain and output a thermal comfort neutral value, so that the control system of the heating system implements heating control based on the thermal comfort neutral value. Since the thermal comfort neutral value is generated based on the adjustment of multiple parameters, the heating system can achieve comfortable heating.
[0189] In addition, in a specific embodiment of the present application, a repeated calculation control module 40 is also included, such as Figure 5 As shown:
[0190] The recalculation control blind hole is used to recalculate the thermal comfort neutral value based on the set calculation frequency.
[0191] In view of the fact that the outdoor temperature and other parameters may change over time, in order to make the heating effect more comfortable, a calculation frequency can be set. The calculation frequency can be regarded as the cycle frequency of the above calculation process. At regular intervals, return to the above step S1, re-collect the outdoor temperature value, and then recalculate the thermal comfort neutral value based on the outdoor temperature value to make the real-time control of the heating system better.
