Description

Freezing prevention system using weather forecast data and actual temperature data

[0001] The present invention relates to a freeze prevention system, and more particularly, to a freeze prevention system utilizing weather forecast data and actual temperature data to predict temperature changes that cause pipes to freeze and supply heat energy of a heater to the pipes.

[0002] Freeze protection systems are installed on pipes and other structures at risk of freezing. They supply heat to these structures, preventing freezing in winter and other environments. These systems do not operate continuously; rather, they detect situations that pose a risk of freezing and are controlled to operate selectively only when such situations occur.

[0003] Existing freeze protection systems are designed to handle unexpected cold snaps in winter by setting specific start and stop temperatures, and their operation is determined based on these set temperatures. For example, some freeze protection systems operate when temperatures fall below 5°C and shut down when temperatures rise above 7°C. This is because freeze protection activation and shutdown conditions are limited to uncertain surprise cold snaps.

[0004] The problem with these conventional freeze protection systems is that they operate based solely on current temperature information without considering future weather changes, which can result in unnecessary energy waste.

[0005] With the recent rise in electricity costs, there is a growing demand to effectively control freeze protection systems to reduce energy consumption costs.

[0006] The purpose of the present invention is to provide a freeze prevention system that uses weather forecast data and actual temperature data to predict temperature changes that cause pipes to freeze and to supply heat energy of a heater to the pipes.

In order to facilitate an overall understanding in describing the present invention, identical reference numerals will be used for identical components in the drawings, and redundant descriptions of identical components will be omitted.

[0030] Hereinafter, a freeze prevention system according to one embodiment of the present invention will be described with reference to the attached drawings.

[0031] FIG. 1 is a diagram showing the configuration of a freeze prevention system utilizing weather forecast data and actual temperature data according to an embodiment of the present invention.

[0032] A freeze prevention system (100) utilizing weather forecast data and actual temperature data according to an embodiment of the present invention includes an outside temperature sensor (102), a pipe temperature sensor (103), a heater (104), a temperature data providing server (110), a heater monitoring device (120), and a control panel (130).

[0033] The outside temperature sensor (102) is installed outside and measures the outside temperature.

[0034] A pipe temperature sensor (103) is installed in a pipe (101) to measure the pipe temperature. The pipe (101) includes all pipes that are at risk of freezing in winter, such as fire pipes, water supply and drainage pipes, sanitary pipes, and rainwater pipes.

[0035] A heater (104) is installed in a pipe (101) and functions to supply thermal energy to the pipe (101). The heating element of the heater (104) may be one of a ceramic heater, a PTC (Positivie Temperature Coefficient) heating element, and a surface heating element. In the present invention, the type of heating element is not limited to the above-described types of heating elements.

[0036] The weather data provision server (110) may be a server that generates and stores weather data measured by location, time zone, and date in each region. The weather data provision server (110) may be a server that provides weather data provided by the Korea Meteorological Administration, a portal site, etc.

[0037] The heater monitoring device (120) is installed at the start and end positions of the heater (104) installed in the pipe (101), and can be installed at multiple positions in places where the temperature deviation is severe.

[0038]

[0039] The heater monitoring device (120) includes a temperature monitoring unit (121), a heater operation display unit (122), and a power monitoring unit (123).

[0040] The temperature monitoring unit (121) is connected to the outside temperature sensor (102) and the pipe temperature sensor (103) to monitor the outside temperature and the pipe temperature. The temperature monitoring unit (121) can comprehensively determine the outside temperature and the pipe temperature.

[0041] The power monitoring unit (123) is electrically connected to the heater (104) and monitors the power supplied to the heater (104).

[0042] The heater operation display unit (122) displays the operating status of the heater (104). The heater operation display unit (122) can display whether the heater (104) is operating, the outside temperature, the pipe temperature, etc.

[0043] The control panel (130) receives weather data including weather forecast data from a weather data provision server (110) and controls the power supplied to the heater (104).

[0044] The control panel (130) specifically includes an information receiving unit (131), a storage unit (132), a control unit (133), a display unit (134), a control unit (135), and a power control unit (136). In addition, it further includes an integrated control unit (111) that performs control and monitoring functions of all control panels (130) within the building.

[0045] The information receiving unit (131) receives temperature monitoring information from the temperature monitoring unit (121) and receives weather data including weather forecast data from the weather data providing server (110). For this purpose, the information receiving unit (131) may be connected to the weather data providing server (110) via a network such as the Internet. In some cases, a separate data processing server may exist that receives weather data from the Korea Meteorological Administration or a portal site, processes the weather data, and provides it to the information receiving unit (131), and the information receiving unit (131) may be connected to this data processing server.

[0046] The information receiving unit (131) can receive weather data according to predetermined criteria from the weather data providing server (110). The information receiving unit (131) can receive the outside temperature and the pipe temperature from the temperature monitoring unit (121) and store them in the storage unit (132). In addition, the information receiving unit (131) can periodically receive temperature data by hour and date from the weather data providing server (110). The weather data can include weather forecast data regarding the weather. The predetermined criteria can be the location where the freeze protection system (100) is installed, the forecast target time range, the type of weather data, etc.

[0047] In order to receive accurate temperature information, the information receiving unit (131) can obtain temperature information of the corresponding area based on information on the area or location where the freeze protection system (100) is installed.

[0048] Meteorological data can include temperature data and non-temperature data. Temperature data refers to data about the temperature at a given time in a specific area, while non-temperature data refers to non-temperature-related meteorological data. Non-temperature data can include daytime, nighttime, sunrise and sunset times, sunlight amount, rainfall, and snowfall data.

[0049] The storage unit (132) stores information related to the operation method of the heater (104). Here, the operation method of the heater (104) includes the driving form of the heater (104) and control information for controlling it.

[0050] The control unit (133) determines the operation method of the heater (104) based on weather data. For example, the control unit (133) determines the operation method of the heater for preventing freezing of the pipe (101) based on at least one of the weather forecast data received by the information receiving unit (131), the measured outdoor temperature, and the measured pipe temperature, and can control the power control unit (136) according to the determined operation method. The control unit (133) can receive data on at least one of the weather forecast data, the measured outdoor temperature, and the measured pipe temperature received from the weather data providing server (110) and store the data in the storage unit (132).

[0051] The specific method by which the control unit (133) determines the operating method of the heater (104) will be described in detail below.

[0052] Here, the method of operation of the heater (104) may be information about whether the heater (104) is operating (on / off), the operating time of the heater (104), and the individual parts of the heater (104) that are operating when the heater (104) is divided into multiple parts.

[0053] The display unit (134) can display the outside temperature, pipe temperature, temperature data received from the temperature data providing server (110), operation status of the heater (104), etc. according to the control of the control unit (133). In addition, the display unit (134) can display information related to the control of the heater (104).

[0054] The control unit (135) displays the operating status of the heater (104) and receives a control signal. The control unit (135) receives a control signal from the integrated control unit (111) and controls the control unit (133) according to the received control signal, thereby controlling the control panel (130).

[0055] In some cases, the control unit (135) may provide an operating status that can be displayed on the terminal of the administrator or user of the freeze protection system. In addition, the administrator or user of the freeze protection system may input various information necessary for the control unit (133) to determine the operating method of the heater (104) through the control unit (135).

[0056] The power control unit (136) is connected to the power monitoring unit (123) and controls the power supplied to the heater (104) according to the operating method of the heater (104). The power control unit (136) is connected to the control unit (133) and receives information on the operating method of the heater (104) determined by the control unit (133).

[0057]

[0058] FIG. 2 is a diagram showing the appearance of rapid temperature changes in weather forecast data of a weather data provision server according to an embodiment of the present invention.

[0059] The control unit (133) will be described as determining the operating method of the heater (104) based on weather forecast data among weather data.

[0060] If a rapid drop in temperature is expected based on weather forecast data, the control unit (133) can control the heater (104) to operate in advance even if the current outside temperature or pipe temperature does not meet the operating conditions. For example, as shown in FIG. 2, if weather forecast data confirms that the temperature will drop to 0°C in 1 hour from now and will continue to drop for 6 hours, the control unit (133) can decide to preemptively operate the heater (104) at the current time based on this.

[0061] As another example, if weather forecast data indicates that the current outside temperature has temporarily risen to 5℃, but the current pipe temperature remains at 0℃ and is expected to drop below -5℃ again in the near future, then the risk of freezing can be determined to be high.

[0062] As another example, the control unit (133) may determine an operating method such that when a rapid drop in temperature is expected based on weather forecast data, but the temperature rises again within a short period of time, the risk of freezing is low, and the heater (104) does not operate under conditions where the pipe temperature is above the freezing point.

[0063] Specifically, if weather forecast data indicates that the current outside temperature has temporarily dropped to -5℃, but is expected to rapidly rise to 5℃ in 3 hours, the risk of freezing can be judged to be low.

[0064] The control unit (133) can determine a specific operation method for operating the heater (104) in advance by considering the power efficiency of the heater (104). Specifically, the optimal operation method can be determined by comparing the power consumption and power cost between operating the heater (104) at an intermediate power level 2 hours before a sharp drop in temperature and operating the heater (104) at a maximum power level 30 minutes before a sharp drop in temperature. Here, the control unit (133) can consider not only the power consumption according to the operation method of the heater (104), but also the power cost for the corresponding operation time. The control unit (133) can determine the operation method based on the power consumption or power cost according to the operation method of the heater (104).

[0065] The control unit (133) can obtain at least one of power efficiency information and power price information for the freeze protection system (100) to check power consumption or power cost. Here, the power efficiency information may be information on the relationship between the strategic consumption and the temperature change amount of the pipe (101).

[0066] In addition to the Korea Meteorological Administration's temperature data, customized information based on the pipe installation location may be reflected as needed. The control unit (133) may determine an efficient operation method for the heater (104) by considering the calculated advance operation time for the heater (104) to prevent the pipe (101) from freezing, and transmit the result to the power control unit (136).

[0067] In other words, assuming that the time is calculated by operating the heater (104) at the aforementioned freezing point, for example, if the time is 8 hours after the heater (104) must be operated, the target temperature of the heater (104) can be sequentially increased by setting it in 20-minute increments starting from 1 hour and 30 minutes before.

[0068] The control unit (133) may correct the temperature data by considering the difference in position in consideration of the reference position of the weather data and the actual installation position of the freeze protection system (100).

[0069] Specifically, when the actual installation location of the freeze protection system (100) is between the first reference location of the weather data and the second reference location of the weather data, the control unit (133) can correct the temperature data using an average value of the weather data of the first reference location and the weather data of the second reference location.

[0070] For example, the control unit (133) can receive only the temperature data of area A adjacent to the location where the freeze protection system (100) is installed from the temperature data providing server (110), and if it is confirmed that the location where the freeze protection system (100) is installed is typically about 3℃ lower in temperature than area A, the control unit (133) can estimate and utilize the temperature information of the received temperature data of area A lowered by 3℃ as the temperature information of the location where the freeze protection system (100) is actually installed.

[0071] The control unit (133) can determine the operating method of the heater (104) by considering the outside temperature together with the weather forecast data among the weather data.

[0072] The meteorological data includes temperature data and rain temperature data, and the rain temperature data includes information on at least one of day time, night time, sunlight amount data, rainfall data, and snowfall data.

[0073] The control unit (133) can determine the operating method of the heater (104) based on the first relationship information between the weather data and the outside temperature.

[0074] The control unit (133) can determine the operating method of the heater (104) by considering the difference between the weather forecast data and the outside temperature. For example, if the outside temperature is typically 5°C lower than the weather forecast data, the heater operation decision can be determined by considering this difference. For example, if the operating condition of the heater (104) is assumed to be 4°C, if the lowest temperature of the weather forecast data is 8°C, the control unit (133) can determine that the heater (104) operates by predicting the outside temperature of the corresponding installation location to be 3°C by considering the above difference (the outside temperature is set to be 5°C lower). Through this, the operation of the heater (104) can be determined not only based on the weather forecast data, but also based on the actual outside temperature of the area where the freeze protection system is installed.

[0075] The first relationship information may include difference information between temperature data and outside temperature, and relationship information between non-temperature data.

[0076] For example, the first relationship information may be that the freezing prevention system is configured to operate at an outside temperature that is 4°C higher than the weather forecast during the day, but 5°C lower than the weather forecast during the night, during rain, and during snowfall. In this case, if the weather forecast data for 4 hours later predicts that the temperature will drop to -1°C, but 4 hours later is daytime and no rain or snowfall is expected, the actual outside temperature at that time may be determined to be 3°C. However, in the same situation, if 4 hours later is nighttime, the actual outside temperature at that time may be determined to be -6°C, and the operation method may be determined to be to operate the heater (104).

[0077] The control unit (133) can obtain characteristic information related to the first relationship information between weather data and the outside temperature, and determine the operating method of the heater (104) based on the characteristic information. Here, the characteristic information may be information related to daytime, nighttime, sunlight, rainfall, and snowfall conditions. The control unit (133) can independently determine this characteristic information, or the control unit (133) can directly receive characteristic information that causes a difference between weather forecast data and the outside temperature through the control unit (135).

[0078] In the case of the installation location of the freeze protection system (100), if there is a characteristic that the difference between the weather forecast data and the outside temperature is 2℃ in normal times, but the difference changes to 6℃ during rain, characteristic information can be input.

[0079] Such characteristic information is input through the control unit (135), and the control unit (133) can determine the operation method of the heater (104) that corresponds to the conditions related to the characteristic information when they are satisfied.

[0080] The control unit (133) can determine the operating method of the heater (104) by considering the pipe temperature together with the weather forecast data among the weather data.

[0081] The reason for considering the pipe temperature is that the amount of heat loss may vary depending on the insulation condition of the pipe (101) and the environmental conditions after heating by the heater, such as indoor / outdoor of the building.

[0082] The control unit (133) can correct weather forecast data based on the difference information between weather data and the outside temperature, and determine the operating method of the heater (104) based on the corrected weather forecast data.

[0083] The control unit (133) can correct weather forecast data based on the reference position that serves as the basis for weather data and the installation position where the freeze protection system (100) is installed, and determine the operation method of the heater (104) based on the corrected weather forecast data.

[0084] The control unit (133) can receive the pipe temperature from the temperature monitoring unit (121) and determine the operating method of the heater (104) based on the second relationship information between the weather data and the pipe temperature.

[0085] The second relationship information includes prediction information on the pipe temperature according to the heat loss amount of the pipe (101). The control unit (133) can obtain the loss of the insulated portion of the pipe and, based on the loss of the insulated portion, determine at least one of the heat loss amount of the pipe (101) and the prediction information on the pipe temperature.

[0086] The temperature compensation algorithm can determine whether to use the temperature data received from the weather data providing server (110) to determine the operating method of the heater (104) based on the difference between the temperature data received from the weather data providing server (110) and the outside temperature measured by the outside temperature sensor (102).

[0087] For example, the control unit (133) calculates a temperature difference value, which is the difference between the temperature of the temperature data and the outside temperature, and if the calculated temperature difference value is greater than a preset first threshold value, it determines that it is difficult to directly apply the temperature data received from the weather data provision server (110) to the corresponding freeze prevention system, and thus the control unit (133) can determine the operation method of the heater (104) based only on the outside temperature measured by the outside temperature sensor (102).

[0088]

[0089] Below, the heat loss of the pipe (101) is calculated to determine roughly how much heat energy must be supplied to prevent the pipe (101) from freezing.

[0090] The heat loss of the pipe is calculated using the following mathematical equation 1.

[0091]

[0092] Here, is the heat loss (J), is the heat transfer coefficient (W / m 2 K) and, is the external surface area of ​​the pipe (m 2 ) and, is the difference between the pipe temperature and the outside temperature (K), and t represents time.

[0093] For example, the pipe outer diameter is 2.7 cm, the pipe length is 1 m, the outside temperature is -10 ° C, the pipe temperature is 4 ° C, and the heat transfer coefficient is 15 W / m 2 Assume K (without insulation).

[0094] The external surface area of ​​the pipe (101) is calculated using the following mathematical equation 2.

[0095]

[0096] A = × 0.027m × 1m 0.0848m 2

[0097] The temperature difference with respect to the outside temperature is 4℃ - (-10℃) = 14K.

[0098] When the outside temperature is -10℃, = 15W / m 2 K × 0.0848m 2 × 14K × 3600 It's 64368J.

[0099] The output requirement of the heater (104) must be such that the heater (104) continuously supplies energy to prevent the water inside the pipe from freezing. The required energy supply must be equal to the heat loss amount mentioned above.

[0100] When the outside temperature is -10℃, the output demand of the heater (104) is 64368J / 3600s It's 17.88W.

[0101] The energy that must be supplied to the heater (104) to prevent the pipe (101) from freezing may vary depending on the outside temperature and the insulation status of the pipe (101). The output of the heater (104) required for 1 m of the pipe (101) can be calculated to be approximately 18 W when the outside temperature is -10°C (without using insulation).

[0102] Therefore, the heater (104) must continuously supply an output of approximately 18 W to prevent the pipe (101) from freezing during the early morning hours when the outside temperature drops to -10°C. However, the output required by the heater (104) may vary depending on the insulation condition of the pipe (101) and actual environmental conditions, and it is desirable to design it with an appropriate margin of error.

[0103] Additionally, when using insulation, heat loss from the pipe (101) can be significantly reduced, thereby significantly reducing the amount of energy required to prevent pipe freezing.

[0104] If the outside temperature is expected to drop to -10℃ in the early morning, the heater (104) must be operated before the internal temperature of the pipe (101) drops below zero.

[0105] Below, the control unit (133) determines how many hours in advance the heater (104) should be operated to prevent the pipe (101) from freezing.

[0106] The initial temperature of the pipe (101) is assumed to be 10°C, and the target temperature is assumed to be such that the pipe temperature does not drop below 4°C.

[0107] The mass of water in the pipe is based on a 1-meter long pipe (101), and the specific heat of water is c=4.186J / g℃.

[0108] When the inner diameter of the pipe (101) is 2.7 cm (0.027 m), the volume and mass of the water contained in the 1 meter long pipe (101) are calculated as shown in the following mathematical equation 3.

[0109]

[0110] 0.000573 m 3 This is it.

[0111] Density of water 1000kg / m 3 Therefore, the mass m is V × = 0.000573m 3 × 1000kg / m 3 0.573kg It weighs 573g.

[0112] The energy required to drop the tube temperature from 10℃ to 4℃ is calculated as shown in the following mathematical equation 4.

[0113] It is recommended that the reference temperature to prevent freezing of the pipe (101) be maintained at 4°C or higher. Therefore, the target temperature of the pipe (101) is assumed to be 4°C.

[0114]

[0115] Here, Q is the energy required for temperature change, m is the mass of water, c is the specific heat of water c=4.186J / g℃, = 10℃ - 4℃ = 6℃.

[0116] Q = 573g × 4.186J / g℃ × 6℃ It's 14398J.

[0117] The total energy that the heater (104) must supply is the sum of the heat loss and the energy required for temperature change (64368J + 14398J 78766J).

[0118] As in mathematical expression 5, the total energy to be supplied by the heater (104) and the output of the heater (104) are used to calculate the time for which the heater (104) must be operated in advance.

[0119] Assuming that the output of the heater (104) is 18W (18J / s), the required time is calculated by dividing the output of the heater (104) by the total energy that the heater (104) must supply. 4375.8 / 3600 1.21 hours).

[0120]

[0121] Here, t is the time for which the heater (104) must be operated in advance, Q is the total energy to be supplied by the heater (104), and P represents the output of the heater (104).

[0122] If the outside temperature is expected to drop to -10°C in the early morning, it is necessary to operate the heater (104) approximately 1.21 hours before the time when the pipe (101) is at risk of freezing.

[0123] The present invention allows for appropriate adjustment of heater output, taking into account the varying heat loss caused by pipe location and insulation thickness. This effectively compensates for heat loss in the pipe and maintains the internal temperature of the pipe through efficient energy use.
