Technical Field

[0001] This invention relates to the field of intelligent control, specifically to a water temperature regulation method, device, equipment, and storage medium. Background Technology

[0002] Existing humidity and temperature control methods require knowing and controlling the dew point temperature of the air—the temperature at which water vapor in the air begins to condense into liquid water. Traditional humidity control methods are usually based on fixed setpoints, but these fixed setpoints can lead to humidity overshoot, resulting in excessive moisture in the air, affecting comfort and equipment performance. Furthermore, traditional heat pump units suffer from insufficient accuracy and stability in temperature regulation, potentially leading to energy waste and temperature fluctuations. Therefore, a novel method and system are needed that can dynamically adjust the temperature setpoint based on system response to better meet actual needs. Summary of the Invention

[0040] To address existing water temperature regulation methods, this application uploads sensor data from each fresh air unit within the whole-house control system to a gateway for data processing. This process yields the outlet dew point temperature of the whole-house control system, compares it with the target outlet dew point temperature, calculates the maximum outlet dew point temperature overshoot, and, based on this overshoot, matches the corresponding water temperature regulation amount from a preset deviation water temperature regulation table. A corresponding water temperature regulation command is then generated and sent to the heat pump unit. This solution controls the heat pump unit's water temperature regulation by calculating the overshoot, improving the temperature control accuracy and stability of the heat pump unit and increasing water temperature regulation efficiency.

[0042] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 A schematic diagram of the first embodiment of the water temperature adjustment method provided by the present invention is shown. The method specifically includes the following steps:

[0043] 101. Obtain sensor data from each fresh air device within the whole-house control system and upload it to the gateway for data processing to obtain the actual outlet dew point temperature of each fresh air device.

[0044] The sensor data includes temperature data acquired by each fresh air unit via a temperature sensor and humidity data acquired via a humidity sensor. The outlet dew point temperature described in this solution is the temperature generated when air is saturated at a specific temperature and relative humidity. It can be either the outdoor dew point temperature or the indoor dew point temperature. The temperature and humidity sensors need to be installed at the air outlet to measure the air temperature and relative humidity in real time, calculate the water vapor saturation pressure, and then calculate the outlet dew point temperature.

[0045] This step first requires collecting the outlet air temperature and humidity data from the AHU (Air Handling Unit). Commonly used temperature sensors include thermistors, thermocouples, or digital temperature sensors, and humidity sensors include humidity sensors or capacitive humidity sensors. These sensors are connected to a data acquisition system to record and save the temperature and humidity data. Based on the relative humidity measured by the humidity sensor, it is converted to absolute humidity (typically in grams per cubic meter) using the corresponding formula. The dew point temperature is then calculated using the dew point temperature calculation formula. Furthermore, in practical applications, to improve the accuracy of the calculation, it may be necessary to consider some temperature and humidity compensation factors. For example, the saturated water content of air differs at different temperatures, so these factors may need to be taken into account when calculating the dew point temperature.

[0046] To calculate the dew point temperature based on temperature and relative humidity, the following formula can be used:

[0047] 1. Magnus formula: Dew point temperature (unit: degrees Celsius) = (243.12 * (ln(relative humidity / 100) + (17.62 * temperature) / (243.12 + temperature))) / (17.62 - ln(relative humidity / 100) - (17.62 * temperature) / (243.12 + temperature));

[0048] 2. Arden Buck formula: Dew point temperature (unit: degrees Celsius) = (235.5 * ((log(relative humidity / 100) + ((17.67 * temperature) / (temperature + 243.5))) / (17.67 - (log(relative humidity / 100) + ((17.67 * temperature) / (temperature + 243.5)))))).

[0049] Relative humidity is expressed as a percentage, ranging from 0 to 100. Temperature is the air temperature, usually expressed in degrees Celsius.

[0050] In this embodiment, the saturated water vapor partial pressure is a function of absolute temperature, and its calculation formulas include the Goff-Gratch formula, the Magnus formula, the Hyland-Wexler formula, the Tetens formula, the Buck formula, and the Marti-Mauersberger formula. The water vapor saturation pressure is calculated based on temperature data, and the water vapor partial pressure is calculated based on humidity data and the water vapor saturation pressure. Based on the water vapor partial pressure, the dew point temperature is calculated using a preset dew point temperature calculation formula to obtain the actual outlet dew point temperature of each fresh air device. The saturation pressure of water vapor refers to the pressure at which water vapor and liquid water are in equilibrium at a specific temperature. The saturation pressure of water vapor can be calculated using the saturation water vapor pressure formula. For the relationship between the saturation pressure P (in Pascals, Pa) and temperature T (in degrees Celsius, °C) calculated using Maxwell's equations: log10(P) = A - (B / (T+C)), where A, B, and C are constants corresponding to the units (log10(P) and T). For the relationship between the saturation pressure P (in Pascals, Pa) and temperature T (in degrees Celsius, °C) calculated using Anthony's equations (applicable to temperatures between -100 °C and 374 °C): P = 10^(A - (B / (T+C))), again, A, B, and C are constants corresponding to the units (P and T). The partial pressure of water vapor refers to the partial pressure of water vapor in the air, usually measured in Pascals (Pa) or kilopascals (kPa). Calculating the partial pressure of water vapor requires knowing the relative humidity and the saturation pressure of water vapor. The following formula can be used to calculate the partial pressure of water vapor: Partial pressure of water vapor (Pa) = Relative humidity × Saturation pressure of water vapor (at the same temperature). Specifically, first convert the relative humidity to a decimal form. Then, based on the saturation pressure of water vapor at a specific temperature, calculate the saturation pressure using Maxwell's equations or Anthony's equations. Finally, multiply the decimal form of the relative humidity by the saturation pressure of water vapor to obtain the partial pressure of water vapor. Example: Assuming a temperature of 25°C and a relative humidity of 60%, first calculate the saturation pressure of water vapor at this temperature using Anthony's equations, and then calculate the partial pressure of water vapor.

[0051] The relative humidity is used to convert the partial pressure of water vapor into saturation pressure: Relative humidity = partial pressure of water vapor / saturation pressure of water vapor. Using the relative humidity value and the saturation pressure of water vapor, we can then use Maxwell's equation or Anthony's equation to calculate the saturation temperature (the temperature at which water vapor is saturated). Finally, the saturation temperature obtained is the dew point temperature. For example, suppose that at atmospheric pressure, the saturation pressure of water vapor is 10,000 Pascals (Pa), and the partial pressure of water vapor is 8,000 Pascals (Pa). Using Maxwell's equations to calculate the saturation temperature: Relative humidity = 8000 Pa / 10000 Pa = 0.8. Using the relative humidity and saturation pressure, the saturation temperature is calculated using Maxwell's equations: log10(P) = A - (B / (T+C)), A = 8.07131, B = 1730.63, C = 233.426. The temperature T is calculated as: T = (B / (A - log10(relative humidity))) - C = (1730.63 / (8.07131 - log10(0.8))) - 233.426 ≈ 25.7℃. Therefore, with a water vapor partial pressure of 8000 Pascals and a water vapor saturation pressure of 10000 Pascals, the dew point temperature of the air is approximately 25.7℃. This means that below this temperature, water vapor in the air will begin to condense into liquid water.

[0052] 102. Compare the actual outlet dew point temperatures to obtain the outlet dew point temperature of the whole house control system, and compare the outlet dew point temperature with the target outlet dew point temperature to calculate the maximum outlet dew point temperature overshoot.

[0053] The target outlet dew point temperature is the most suitable outlet dew point temperature determined based on the indoor and outdoor humidity levels, thereby controlling the indoor humidity within a reasonable range.

[0054] Specifically, the absolute values ​​of the outlet dew point temperatures of each fresh air unit are compared, i.e., <outlet dew point temperature>#1→#n is read. Here, the subscript represents the serial number of the fresh air unit in the whole-house control system. This subscript means that all fresh air units in the whole-house control system are calculated, and the most unfavorable value is selected for adjustment. n is the number of fresh air units in the current whole-house control system. The absolute values ​​are compared, and the unit with the largest absolute value of the outlet dew point temperature is extracted and denoted as <outlet dew point temperature>#m. At this time, |<outlet dew point temperature>#m - <target outlet dew point temperature>| is the largest, that is, the absolute value of the difference between the outlet dew point temperature and the target outlet dew point temperature is the largest. Therefore, the maximum outlet dew point overshoot is <outlet dew point temperature>#m - <target outlet dew point temperature>, that is, the value of the maximum outlet dew point overshoot is the difference between the outlet dew point temperature with the largest absolute value and the target outlet dew point temperature.

[0055] In another feasible approach, the overshoot is calculated for a unit step response curve of a control system or signal processing system as follows: Let the maximum peak value of the unit step response curve be M (usually the overshoot), and the steady-state value of the unit step response curve be denoted as SS (Steady-State value). Calculate the percentage of overshoot: Overshoot (%) = [(M-SS) / SS] × 100. In the formula, M is the peak value and SS is the steady-state value. If the overshoot value is positive, it means that the peak value exceeds the steady-state value; if the overshoot value is negative, it means that the peak value is lower than the steady-state value.

[0056] 103. Based on the maximum outlet dew point temperature overshoot, match the corresponding water temperature adjustment amount from the preset deviation water temperature adjustment table, and generate the corresponding water temperature adjustment command based on the water temperature adjustment amount and send it to the heat pump host.

[0057] This step utilizes overshoot to coordinate the operation of the fresh air unit and the heat pump unit, achieving water temperature regulation. Specifically, the fresh air unit draws in fresh air from outdoors, filters and treats it, and then delivers the fresh air indoors. The heat pump unit absorbs heat energy from indoors or outdoors through the circulation of the working medium, and then releases the heat energy indoors or outdoors through compression and expansion. The air circulation between the fresh air unit and the heat pump unit can complement each other.

[0058] The following are the general steps for adjusting water temperature by controlling dew point temperature overshoot: First, set the target value for the outlet dew point temperature, i.e., the target outlet dew point temperature. Install humidity and temperature sensors at the air outlet or other suitable locations. Calculate the actual dew point temperature using the dew point temperature formula. Compare the actual outlet dew point temperature with the target outlet dew point temperature to calculate the dew point temperature overshoot. The overshoot can be the absolute value of the actual dew point temperature minus the target dew point temperature. Then, adjust the water temperature of the heat pump unit according to the overshoot value. Increase the water temperature when the overshoot is large, and decrease the water temperature when the overshoot is small. Finally, monitor the dew point temperature again based on the adjusted water temperature to ensure that the overshoot is within the set range.

[0059] In this embodiment, if the actual outlet dew point temperature is 10℃ and the target dew point temperature is 8℃, the overshoot = |10℃ - 8℃| = 2℃. An overshoot of 2℃ indicates that the actual dew point temperature is 2℃ higher than the target dew point temperature. When the gateway directly increases the host water temperature based on the overshoot, it typically involves the feedback and adjustment functions of the control system. Specifically, first, the target water temperature of the heat pump host is set to a set temperature, such as 25℃. A water temperature sensor is installed in the host's water circuit or water pipes to monitor the host water temperature in real time. The real-time monitored host water temperature is compared with the target temperature to calculate the temperature deviation. Based on the calculated temperature deviation, the gateway directly controls the host system to adjust the host water temperature. When the temperature deviation is positive 1℃, the gateway will increase the host water temperature by 1℃ to reduce the deviation. Furthermore, as the host water temperature is adjusted, the water temperature continues to be monitored, and the temperature deviation is recalculated. Through continuous feedback and adjustment, the gateway gradually brings the host water temperature closer to the target value and continuously executes the feedback and adjustment process to achieve stable water temperature control.

[0060] This solution compares the outlet dew point temperature of the whole-house control system with the target outlet dew point temperature, calculates the maximum outlet dew point temperature overshoot, and controls the water temperature of the heat pump unit based on the maximum outlet dew point temperature overshoot. This improves the temperature control accuracy and stability of the heat pump unit, optimizes energy utilization efficiency, and reduces operating costs.

[0061] Please see Figure 2 A schematic diagram of the second embodiment of the water temperature adjustment method provided in this invention, the method specifically includes the following steps:

[0062] 201. Obtain the system mode of the whole-house control system and obtain the corresponding sensor data according to the corresponding system mode.

[0063] In the whole-house control system described in this solution, the system modes include cooling, heating, dehumidification, and ventilation. It must be confirmed that all fresh air units in the system are in the powered-on state and without any abnormal malfunctions.

[0064] Before obtaining the system mode of the whole-house control system, it is necessary to determine whether the system mode has been initialized. If it has not been initialized, that is, when the system first enters or switches to a certain mode, the fresh air unit will run at the preset outlet dew point temperature for a period of time. When the system mode initialization = 0, the target outlet dew point temperature is determined according to the following conditions: When the outdoor humidity is relatively high, the fresh air equipment undertakes the dehumidification task. When the outdoor dew point temperature is greater than the lowest allowable dew point temperature limit of the room, the target outlet dew point temperature is output as = the lowest allowable dew point temperature limit of the room - the fresh air outlet dew point temperature compensation value during dehumidification, and the target outlet dew point temperature ∈ [11℃, 16℃], that is, the target outlet dew point temperature is greater than or equal to 1. 1 degree Celsius and less than or equal to 16 degrees Celsius corresponds to 24℃ / 50% and 26℃ / 50%. When the outdoor humidity is relatively dry, the fresh air equipment undertakes the humidification task. When the outdoor dew point temperature is less than the lower limit of the highest room allowable dew point temperature, the output target outlet dew point temperature = the lower limit of the highest room allowable dew point temperature + the compensation value of the fresh air outlet dew point temperature during humidification, and the target outlet dew point temperature ∈ [7.5℃, 13℃], that is, the target outlet dew point temperature is greater than or equal to 7.5 degrees Celsius and less than or equal to 13 degrees Celsius, corresponding to 18℃ / 50% and 24℃ / 50%. When the outdoor humidity is suitable, the fresh air does not need to be humidified or dehumidified, and the output target outlet dew point temperature = the outdoor dew point temperature.

[0065] If initialized, meaning the system has been running in a certain mode for a period of time, the outlet dew point temperature will begin adaptive adjustment. When system mode initialization = 1, the target outlet dew point temperature = the target outlet dew point temperature at the previous moment + the room dew point, where dew point overshoot = the maximum room dew point temperature overshoot, and temperature overshoot = the maximum room temperature overshoot. Specifically, ① when dew point overshoot < -1.5℃ and temperature overshoot > 1.5℃, the outlet dew point = 0℃; ② when dew point overshoot < -1.5℃ and temperature overshoot ≤ 1.5℃, the outlet dew point = 1℃, increasing the water temperature to avoid over-dehumidification; ③ when dew point overshoot exceeds ...④ when dew point overshoot exceeds 1.5℃, the outlet dew point = 1℃, increasing the water temperature to avoid over-dehumidification; ⑤ when dew point overshoot exceeds 1.5℃, the outlet dew point = 1℃, increasing the water temperature to avoid over-dehumidification; ⑥ when dew point overshoot exceeds 1.5℃, the outlet dew point = 1℃, increasing the water temperature to avoid over-dehumidification; ⑦ when dew point overshoot exceeds 1.5℃, the outlet dew point = 1℃, increasing the water temperature to avoid over-dehumidification; ⑧ when dew point overshoot exceeds 1.5℃, the outlet dew point = 1℃, increasing When the temperature overshoot is greater than 1.5℃ and less than -1.5℃, the outlet dew point is 0℃; when the dew point overshoot is greater than 1.5℃ and the temperature overshoot is greater than or equal to -1.5℃, the outlet dew point is -1℃, the water temperature is reduced, and the dehumidification capacity is increased; when the dew point overshoot is ∈ [-1.5℃, 1.5℃], that is, when the dew point overshoot is greater than or equal to -1.5 degrees Celsius and less than or equal to 1.5 degrees Celsius, the outlet dew point is 0℃, the water temperature is moderate, and the outlet dew point is properly controlled. At the same time, it also follows the principle that when the room dew point (humidity) overshoot conflicts with the room temperature overshoot, the room temperature is adjusted first, and the outlet dew point adjustment function is disabled.

[0066] 202. Calculate the corresponding input parameters based on the sensor data of the whole-house control system, and calculate the overshoot of the dew point temperature based on each input parameter.

[0067] The input parameters include outdoor dew point temperature, the lowest allowable upper limit of room dew point temperature, the highest allowable lower limit of room dew point temperature, the dew point temperature compensation value of fresh air outlet during dehumidification, the dew point temperature compensation value of fresh air outlet during humidification, system mode initialization, maximum room dew point temperature overshoot, and maximum room temperature overshoot.

[0068] For the outdoor dew point temperature, first calculate the water vapor saturation pressure Ps = exp(C1 × T) -1 +C2+C3×10 -2 ×T+C4×10 -5 ×T 2 +C5×lnT), where T=outdoor temperature+273.15, unit K, C1~C5 are constants, then calculate the water vapor partial pressure Pv=outdoor humidity / 100×Ps, the relative humidity here is in %, so it needs to be divided by 100, and finally calculate the outdoor dew point temperature, unit ℃, the saturation temperature corresponding to the water vapor partial pressure, outdoor dew point temperature=243.12×ln(Pv / 611.12) / [17.62-ln(Pv / 611.12)].

[0069] For the lowest room allowable dew point temperature limit, for all room switches = 1, read its <room allowable dew point temperature limit>#1→#n. The lowest room allowable dew point temperature limit = MIN{<room allowable dew point temperature limit>#1→#n}. RTs that are turned off are not included in this calculation.

[0070] For the highest room allowable dew point temperature lower limit, for all room switches = 1, read their room allowable dew point temperature lower limit #1→#n. The highest room allowable dew point temperature lower limit = MAX{<room allowable dew point temperature lower limit>#1→#n}. Closed RTs are not included in this calculation.

[0071] The dew point temperature compensation value is a correction value used to convert a relative humidity value to a relative humidity value at a constant temperature. A standard temperature (e.g., 20°C or 25°C) is typically chosen as the target temperature for compensation. The specific steps are as follows: Measure the temperature and relative humidity in the air. Using the measured temperature and relative humidity values, and the water vapor saturation pressure formula (Maxwell's equation or Anthony's equation), calculate the partial pressure of water vapor in the air (in Pascals). Use the measured temperature as the target temperature, and again use the water vapor saturation pressure formula to calculate the partial pressure of saturated water vapor at the target temperature (in Pascals). The dew point temperature compensation value is the difference between the saturated water vapor partial pressure at the target temperature and the actual water vapor partial pressure. This difference reflects the difference between the actual relative humidity value and the relative humidity value at the target temperature.

[0072] For the maximum room dew point temperature overshoot, for all rooms with switch = 1, read <room dew point temperature overshoot>#1→#n, compare the absolute values ​​|<room dew point temperature overshoot>#1→#n|, and take the maximum value among the absolute values ​​MAX|<room dew point temperature overshoot>#j|. Then the maximum room dew point temperature overshoot = room dew point temperature overshoot#j, and the value of the maximum room dew point temperature overshoot is not an absolute value.

[0073] For the maximum room temperature overshoot, for all room switches = 1, read <room temperature overshoot>#1→#n, compare the absolute values ​​|<room temperature overshoot>#1→#n|, and take the maximum value among the absolute values ​​MAX|<room temperature overshoot>#j|. Then the maximum room temperature overshoot = room temperature overshoot#j, and the value of the maximum room temperature overshoot is not an absolute value.

[0074] 203. Determine the maximum outlet dew point temperature based on the dew point temperatures of each outlet, compare the maximum outlet dew point temperature with the target outlet dew point temperature to obtain the overshoot of the maximum outlet dew point temperature, match the corresponding water temperature adjustment amount, and generate a water temperature adjustment command to send to the heat pump host.

[0075] This solution calculates the maximum outlet dew point temperature overshoot using input parameters in both uninitialized and initialized system modes, thereby controlling the maximum outlet dew point temperature overshoot. The gateway then uses the calculated maximum outlet dew point temperature overshoot value to determine whether to automatically adjust the heat pump unit's water temperature, thus improving the temperature control accuracy and stability of the heat pump unit.

[0076] Please see Figure 3 A schematic diagram of the third embodiment of the water temperature adjustment method provided in this invention, the method specifically includes the following steps:

[0077] 301. Obtain sensor data from each fresh air device within the whole-house control system and upload it to the gateway for data processing to obtain the actual outlet dew point temperature of each fresh air device.

[0078] When calculating the maximum outlet dew point temperature overshoot using the whole-house control system described in this solution, all fresh air units in the system must be in the powered-on state and without any abnormal faults, that is, the equipment has been started and is working normally, and the equipment does not exhibit any abnormal or faulty states during operation.

[0079] To acquire data from the temperature sensors in each fresh air unit, calculate the actual dew point temperature, and upload this data to the gateway, the following steps are required: First, ensure that each fresh air unit is equipped with a temperature sensor to measure the corresponding temperature data. Use appropriate hardware or a controller to collect and store the data measured by each temperature sensor. Based on the collected temperature sensor data, perform necessary data processing, such as calibration and filtering, to obtain accurate temperature values. Using the collected temperature and humidity data, calculate the actual dew point temperature of each fresh air unit using a suitable formula or calculation method. Upload the calculated actual dew point temperature data to the gateway or data center. Data transmission can be achieved through network communication methods such as Wi-Fi, Ethernet, and LoRa. The uploaded actual dew point temperature data is then stored and analyzed at the gateway or data center.

[0080] 302. Compare the actual outlet dew point temperatures to obtain the outlet dew point temperature of the whole house control system.

[0081] Take the absolute value of the actual air outlet dew point temperature of all fresh air devices in the whole house control system, compare the magnitude of each absolute value, obtain the dew point temperature with the largest absolute value, and determine the dew point temperature with the largest absolute value as the air outlet dew point temperature of the whole house control system.

[0082] 303. Compare the outlet dew point temperature with the target outlet dew point temperature and calculate the maximum outlet dew point temperature overshoot.

[0083] In the process of controlling water temperature, automatic adjustment of water temperature is achieved by monitoring and controlling the dew point temperature overshoot. The outlet dew point temperature overshoot refers to the difference between the actual dew point temperature and the set value. During the system response process, the output value exceeds its steady-state value by the maximum extent. Based on this difference, the water temperature of the heat pump unit is controlled to gradually approach the set value, thereby stabilizing the dehumidification or cooling system. For example, in a temperature control system, its goal is to control the indoor temperature at 25 degrees Celsius. When the temperature control system starts adjusting the indoor temperature, the following situations may occur: If the indoor temperature exceeds the target value of 25 degrees Celsius during the adjustment process, for example, reaching 26 degrees Celsius, then the overshoot is positive 1 degree Celsius (i.e., exceeding the target value by 1 degree Celsius), which is a positive overshoot; if the indoor temperature falls below the target value of 25 degrees Celsius during the adjustment process, for example, reaching 24 degrees Celsius, then the overshoot is negative 1 degree Celsius (i.e., falling below the target value by 1 degree Celsius), which is a negative overshoot.

[0084] 304. Based on the overshoot of the maximum outlet dew point temperature, match the corresponding water temperature adjustment amount from the preset deviation water temperature adjustment table.

[0085] Match the corresponding water temperature adjustment amount from the preset deviation water temperature adjustment table. The following is a hypothetical example of a preset deviation water temperature adjustment table:

[0086] Maximum outlet dew point temperature overshoot (°C) Corresponding water temperature adjustment (°C) 0.5 0.2 1.0 0.4 1.5 0.6 2.0 0.8 ...... ......

[0087] In this example, the preset deviation water temperature adjustment table lists different values ​​for the maximum outlet dew point temperature overshoot and their corresponding water temperature adjustment values. For example, if the maximum outlet dew point temperature overshoot of a certain fresh air unit is 1.5℃, then according to the table, the corresponding water temperature adjustment value is 0.6℃. Find the value of the maximum outlet dew point temperature overshoot and locate the matching water temperature adjustment value. Then, apply this water temperature adjustment value to the corresponding fresh air unit and adjust the water temperature setpoint to achieve more precise temperature control.

[0088] 305. Generate a corresponding water temperature adjustment command based on the water temperature adjustment amount and send it to the heat pump host.

[0089] The heat pump unit is the core component of a heat pump system. Also known as a heat pump unit or heat pump equipment, it is a device that can absorb low-temperature heat energy from one heat source (usually air, groundwater, or surface water) through a cycle, raise its temperature, and then release it to another heat source or hot water system.

[0090] This solution indexes the corresponding water temperature adjustment amount from the deviation water temperature adjustment table based on the outlet dew point temperature overshoot, thereby enabling water temperature adjustment of the heat pump unit according to the dew point temperature, which improves the temperature control accuracy and stability of the heat pump unit.
