Description

Technical Field

[0002] With economic development and improved living standards, users' demands for indoor environmental quality are increasing. While traditional air conditioning systems can regulate indoor temperature, they are increasingly unable to meet market demands for health, comfort, and energy efficiency. Therefore, the five-constant system, as a high-end indoor air conditioning solution, is gaining popularity among high-end users and is gradually becoming an important component of modern smart home systems. Specifically, in practical use, the five-constant system achieves uniform indoor temperature regulation through heat exchange on large radiant surfaces such as the floor, walls, or ceiling. However, this method requires maintaining an appropriate temperature difference between the radiant surface temperature and the indoor dew point temperature to prevent condensation. Especially in hot summers, to ensure indoor coolness, the water temperature on the radiant surface needs to be lowered; however, excessively low water temperatures can cause condensation, damaging building materials and affecting the living experience.

[0003] The related technology discloses a method for controlling a five-constant system, comprising: setting a mixing center in the main water circuit of the five-constant system, and controlling the mixing ratio of influent and return water to adjust the water temperature to a safe water temperature that ensures comfort while avoiding condensation. This method effectively reduces the risk of condensation.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] While the relevant technologies have reduced the risk of condensation, the safe water temperature is generally set based on the environmental conditions of the room most prone to condensation. This results in an excessively large temperature control margin in rooms with low dew point temperatures, affecting the efficiency and response speed of temperature regulation.

They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips.

[0040] Figure 1-1 This is a schematic diagram of the structure of a five-constant system provided in an embodiment of this disclosure; combined with Figure 1-1As shown in the illustration, this disclosure provides a five-constant system, including: a heat pump unit 1, a buffer water tank 2, a water distributor 3, a floor radiant device 51, a ceiling radiant device 52, and a water collector 6. Specifically, tap water can be used as the water source for the five-constant system, located at the beginning of the pipeline. The beginning of the pipeline is connected to the buffer water tank 2 via an inlet pipe. The inlet pipe is sequentially equipped with a check valve, a Y-type filter, and a water replenishment valve. In actual use, by placing the water replenishment valve between the buffer water tank 2 and the Y-type filter, when the five-constant system needs to be replenished with water, the filtered tap water in the pipeline will flow into the buffer water tank 2 through the water replenishment valve.

[0041] Optionally, the buffer water tank 2 and the heat pump unit 1 can be connected via an inlet pipe. The inlet pipe is sequentially equipped with a drain valve, an expansion tank, a safety valve, a Y-type filter, a pressure gauge, a water pump, a shut-off valve, and a flexible connection device along the water inlet direction. By controlling the aforementioned devices, water in the buffer water tank 2 can flow into the heat pump unit 1 through the inlet pipe, so that the heat pump unit 1 can be controlled to heat or cool.

[0042] Optionally, the heat pump unit 1 can also be connected to the buffer water tank 2 via an outlet pipe. The outlet pipe is equipped with a flexible connector, a shut-off valve, a flow switch, a safety valve, and a pressure gauge sequentially along the outlet direction. This allows the flow rate of the water in the pipe to be controlled by the flow switch. The buffer water tank 2 is also equipped with an air vent valve and a drain valve.

[0043] Optionally, the buffer tank 2 is connected to the distributor 3 via an outlet pipe. The outlet pipe is equipped with a water pump, and the distributor 3 is equipped with an electric heating actuator 4. The number of electric heating actuators 4 is adapted to the number of rooms in the building where the five-constant system is located. Figure 1-1 The diagram shows that there are 4 electric heating actuators 4 in total. Therefore, the number of rooms in the house where the five constant systems are located is four, and each electric heating actuator 4 is configured to control the on / off state of the water circuit in the corresponding room.

[0044] Optionally, the five-constant system includes two water distributors 3, each with a radiant terminal connected to its other end. The radiant terminal includes a floor radiant device 51 and a ceiling radiant device 52. In a specific embodiment, multiple floor radiant devices 51 are connected to the other end of the water distributor 3, the number of which corresponds to the number of rooms in the house where the five-constant system is located. The other end of each floor radiant device 51 is connected to a water collector 6, which is connected to a buffer tank 2 via an outlet pipe, allowing water in the outlet pipe to flow back to the buffer tank 2. Additionally, multiple ceiling radiant devices 52 are connected to the other end of another water distributor 3. The number of ceiling radiant devices 52 is also adapted to the number of rooms in the house where the five-constant system is located. The other end of each ceiling radiant device 52 is connected to the water collector 6, which is also connected to the buffer tank 2 via an outlet pipe, allowing water in the outlet pipe to flow back to the buffer tank 2.

[0045] Figure 1-2 This is a schematic cross-sectional view of a radiation layer provided in an embodiment of this disclosure; combined with Figure 1-2 As shown, the first room is one of the multiple rooms in the house where the five-constant system is located. A floor radiant heating device 51 is installed at the bottom of the first room, and the water supply to the first room can be controlled by an electrothermal actuator 4. The upper part of the floor radiant heating device 51 is an insulation layer, and the lower part is a heat insulation layer and a reflective layer. Specifically, temperature values ​​can be obtained by arranging temperature sensors in the insulation layer. Similarly, the location and principle of the insulation layers in the other rooms of the house where the five-constant system is located are the same, and will not be elaborated here.

[0046] Figure 2 This is a schematic diagram of a method for controlling a five-constant system provided in an embodiment of this disclosure; combined with Figure 2 As shown, this disclosure provides a method for controlling a five-constant system, including:

[0047] S21, the five constant system acquires the dew point temperature of each room in the building where the five constant system is located, as well as the temperature values ​​collected by the insulation layer temperature sensors of each room.

[0048] S22, the five constant systems determine the target inlet water temperature of the water distributor based on the dew point temperature of each room in the house where the five constant systems are located.

[0049] S23, the five constant systems determine the target state of the corresponding electric heating actuators in each room based on the dew point temperature of each room in the building where the five constant systems are located and the temperature values ​​collected by the insulation layer temperature sensors in each room.

[0050] S24, the five constant systems control the system according to the target inlet water temperature and the target state of the electric heating actuators in each room.

[0051] In this scheme, the five-constant system can determine the dew point temperature of each room in multiple ways. In one example, the system can acquire the relative humidity of the air in each room; based on this relative humidity, the system determines the dew point temperature of each room. In another example, if the room temperature is between 0℃ and 60℃, the dew point temperature can be determined using the Magnus-Tetens approximation method. In an optimized scheme, the saturated water vapor pressure under the design temperature conditions can be determined first, then the actual water vapor partial pressure can be obtained by multiplying the relative humidity by the saturated water vapor pressure, and finally, the corresponding saturated water vapor pressure can be retrieved, with its corresponding temperature used as the dew point temperature. This scheme allows for the acquisition of the dew point temperature of each room in multiple ways.

[0052] In this solution, temperature values ​​(Tba) can be collected by using insulation layer temperature sensors installed in the insulation layers of different rooms. This solution enables accurate temperature data acquisition.

[0053] Furthermore, the five-constant system can determine the target inlet water temperature of the manifold by combining the dew point temperatures of each room in the house where the system is located. Specifically, the five-constant system determines the target inlet water temperature of the manifold based on the dew point temperatures of each room in the house where the system is located, including: comparing the dew point temperatures of each room in the house to select a first temperature and a second temperature; determining a third temperature based on the first and second temperatures; and finally determining the target inlet water temperature of the manifold based on the third temperature. This approach enables precise determination of the target inlet water temperature.

[0054] Furthermore, the five-constant system determines the target state of the corresponding electric heating actuator in each room based on the dew point temperature of each room in the building where the system is located and the temperature values ​​collected by the insulation layer temperature sensors in each room. Specifically, if the five-constant system includes five rooms, namely room one, room two, room three, room four, and room five, then the five-constant system determines the target state of the corresponding electric heating actuator in each room based on the dew point temperature of each room in the building where the system is located and the temperature values ​​collected by the insulation layer temperature sensors in each room, including:

[0055] The five constant systems determine the target state of the electric heating actuator corresponding to the first room based on the dew point temperature of the first room and the temperature value collected by the insulation layer temperature sensor of the first room.

[0056] The five constant systems determine the target state of the electric heating actuator in the second room based on the dew point temperature of the second room and the temperature value collected by the insulation layer temperature sensor of the second room.

[0057] The five constant systems determine the target state of the electric heating actuator corresponding to the third room based on the dew point temperature of the third room and the temperature value collected by the insulation layer temperature sensor of the third room.

[0058] The five constant systems determine the target state of the electric heating actuator corresponding to the fourth room based on the dew point temperature of the fourth room and the temperature value collected by the insulation layer temperature sensor of the fourth room.

[0059] The five constant temperature system determines the target state of the electric heating actuator corresponding to the fifth room based on the dew point temperature of the fifth room and the temperature value collected by the insulation layer temperature sensor of the fifth room.

[0060] The target state includes both on and off states. The principle for determining the target state of the electrothermal actuators in each room is the same. This scheme allows for the accurate determination of the target state of the electrothermal actuators in each room.

[0061] Furthermore, the five constant systems can be controlled according to the target inlet water temperature and the target state of the corresponding electric heating actuators in each room.

[0062] The method for controlling a five-constant system provided in this disclosure can accurately calculate the target inlet water temperature of the manifold by real-time monitoring of the dew point temperature and insulation layer temperature in each room of the house where the five-constant system is located. Based on this, the optimal operating state of the electric heating actuators in each room can be set, thereby achieving refined control of the five-constant system. This not only effectively avoids condensation problems on radiant surfaces but also significantly improves the temperature regulation efficiency and response speed of the five-constant system, while reducing energy consumption, providing users with a more comfortable and energy-efficient living environment.

[0063] Figure 3 This is a schematic diagram of a method for determining a target inlet water temperature provided in an embodiment of this disclosure; combined with Figure 3 As shown, optionally, in step S22, the five-constant system determines the target inlet water temperature of the manifold based on the dew point temperature of each room in the building where the five-constant system is located, including:

[0064] S31, the five constant system compares the dew point temperatures of each room in the house where the five constant system is located in order to select the first temperature and the second temperature.

[0065] S32, the five constant temperature system determines the third temperature based on the first and second temperatures.

[0066] S33, the five constant systems determine the target inlet water temperature of the water distributor based on the third temperature.

[0067] The first temperature is the maximum dew point temperature of each room, and the second temperature is the minimum dew point temperature of each room.

[0068] In this scheme, the first temperature is the maximum dew point temperature of each room, and the second temperature is the minimum dew point temperature of each room. For example, if a five-constant system includes five rooms: room 1, room 2, room 3, room 4, and room 5, and the dew point temperature of room 1 is 18℃, room 2 is 20℃, room 3 is 16℃, room 4 is 15℃, and room 5 is 13℃, then the dew point temperatures of the five rooms can be compared to determine the maximum dew point temperature as 20℃ and the minimum as 13℃. Thus, the first temperature can be determined as 20℃ and the second temperature as 13℃. This scheme allows for precise determination of the first and second temperatures.

[0069] Furthermore, the five-constant system can determine a third temperature by combining the first and second temperatures. Specifically, the five-constant system determines the third temperature based on the first and second temperatures by calculating the difference between the first and second temperatures. If the difference is less than a first preset threshold, the system uses the minimum dew point temperature of all rooms as the third temperature. Alternatively, if the difference is greater than or equal to the first preset threshold, the system uses the average dew point temperature of all rooms as the third temperature. This method allows for accurate calculation of the third temperature.

[0070] Furthermore, the five-constant system can determine the target inlet water temperature of the manifold by incorporating a third temperature. Specifically, the five-constant system determines the target inlet water temperature of the manifold based on the third temperature, including: if the third temperature is within a preset temperature range, the five-constant system determines the third temperature as the target inlet water temperature of the manifold; or, if the third temperature is less than a second preset threshold, the five-constant system determines a fourth temperature as the target inlet water temperature of the manifold; or, if the third temperature is greater than a third preset threshold, the five-constant system determines a fifth temperature as the target inlet water temperature of the manifold. This scheme, by combining the dew point temperature of each room in the building where the five-constant system is located, can accurately determine the target inlet water temperature of the manifold, providing a precise data foundation for the anti-condensation control of the five-constant system.

[0071] Optionally, S32, the five constant temperature system determines the third temperature based on the first temperature and the second temperature, including:

[0072] The five constant temperature system calculates the difference between the first and second temperatures.

[0073] If the difference is less than a first set threshold, the five-constant system uses the minimum dew point temperature of each room as the third temperature. Alternatively,

[0074] If the difference is greater than or equal to the first set threshold, the five constant temperature system will use the average dew point temperature of each room as the third temperature.

[0075] In this scheme, the five constant temperature system can pre-store a first set threshold. In one example, the first set threshold is 5 degrees Celsius. Thus, after calculating the difference between the first and second temperatures, if the difference is less than 5 degrees Celsius, the minimum dew point temperature of each room is used as the third temperature. Alternatively, if the difference is greater than or equal to 5 degrees Celsius, the average dew point temperature of each room is used as the third temperature. For example, if the first temperature T1 is 20 degrees Celsius and the second temperature T2 is 13 degrees Celsius, the difference between the first and second temperatures can be calculated to be 5 degrees Celsius, and the average dew point temperature of each room can be used as the third temperature, i.e., the third temperature T3 = (18 degrees Celsius + 20 degrees Celsius + 16 degrees Celsius + 15 degrees Celsius + 13 degrees Celsius) ÷ 5 = 16.4 degrees Celsius. Thus, the third temperature can be determined as 16.4 degrees Celsius. This scheme can accurately determine the third temperature by considering the differences in dew point temperatures between different rooms.

[0076] Optionally, S33, the five constant temperature system determines the target inlet water temperature of the distributor based on the third temperature, including:

[0077] When the third temperature is within the preset temperature range, the five-constant system determines the third temperature as the target inlet water temperature for the distributor. Alternatively,

[0078] If the third temperature is lower than the second set threshold, the five-constant system will determine the fourth temperature as the target inlet water temperature for the distributor. Alternatively,

[0079] If the third temperature is greater than the third set threshold, the five constant temperature system will determine the fifth temperature as the target inlet water temperature of the water distributor.

[0080] In this solution, the five-constant system can preset a second and a third set threshold based on economic and comfort considerations. As an example, the second set threshold is 12℃, and the third set threshold is 24℃. The preset temperature range is from the second to the third set threshold, i.e., from 12℃ to 24℃. Thus, when the third temperature is between 12℃ and 24℃, the five-constant system determines the third temperature as the target inlet water temperature for the distributor. When the third temperature is less than 12℃, the five-constant system determines the fourth temperature as the target inlet water temperature for the distributor, which is 12℃. When the third temperature is greater than 24℃, the five-constant system determines the fifth temperature as the target inlet water temperature for the distributor, which is also 12℃. This solution enables precise determination of the target inlet water temperature, providing accurate data technology for the precise control of the five-constant system, thus avoiding condensation and ensuring stable system operation.

[0081] Optionally, the five-constant system includes a heat pump unit, which is connected to a buffer water tank via pipes. The method further includes:

[0082] The five constant systems periodically acquire the target inlet water temperature of the water distributor.

[0083] The five constant systems adjust the outlet water temperature of the heat pump unit based on the difference between the target inlet water temperature and the current inlet water temperature of the distributor.

[0084] In this solution, the dew point temperature of each room can be periodically acquired to periodically determine the target inlet water temperature of the manifold. The acquisition cycle for the dew point temperature can be preset. Understandably, to ensure timely heating or cooling of the water in the heat pump unit, the acquisition cycle can be set to 10 minutes. This allows the dew point temperature of each room to be acquired every 10 minutes, thus periodically determining the target inlet water temperature of the manifold.

[0085] Furthermore, the five-constant system can periodically adjust the heat pump unit's outlet water temperature by combining the difference between the target inlet water temperature and the current inlet water temperature of the manifold. In one example, the heat pump unit's outlet water temperature can be adjusted using a PID (Proportional-Integral-Derivative) method. This approach, by periodically acquiring the target inlet water temperature of the manifold and comparing it with the current actual inlet water temperature, can accurately determine the gap between the current heating or cooling demand and the actual situation. Based on this gap, the five-constant system can adjust the heat pump unit's outlet water temperature in a timely manner, ensuring a high degree of matching between energy supply and demand, avoiding energy waste, and thus improving overall energy efficiency.

[0086] Figure 4 This is a schematic diagram of a method for determining a target state of an electrothermal actuator provided in an embodiment of this disclosure; combined with Figure 4 As shown, optionally, if the house containing the five constant systems includes the first room, then the method includes:

[0087] S21, the five constant system acquires the dew point temperature of each room in the building where the five constant system is located, as well as the temperature values ​​collected by the insulation layer temperature sensors of each room.

[0088] S421, the five-constant system determines the target state of the electric heating actuator corresponding to the first room to be "on" if the temperature value collected by the temperature sensor of the insulation layer in the first room is greater than or equal to the dew point temperature of the first room. Alternatively,

[0089] S422, when the temperature value collected by the insulation layer temperature sensor in the first room is lower than the dew point temperature of the first room, the five constant systems determine that the target state of the electric heating actuator corresponding to the first room is the off state.

[0090] In this scheme, the principle for determining the target state of the electric heating actuators for each room is the same. Taking the first room as an example, the five-constant system can compare the temperature value Tba collected by the insulation layer temperature sensor of the first room with the dew point temperature of the first room. If the temperature value collected by the insulation layer temperature sensor of the first room is greater than or equal to the dew point temperature of the first room, the target state of the electric heating actuator corresponding to the first room is determined to be the "on" state. With this scheme, when the insulation layer temperature is greater than or equal to the dew point temperature, it can be determined that there is no risk of condensation on the radiant surface, and rapid cooling can be achieved by maintaining the flow of chilled water. Similarly, if the temperature value collected by the insulation layer temperature sensor of the first room is less than the dew point temperature of the first room, the target state of the electric heating actuator corresponding to the first room is determined to be the "off" state. With this scheme, when the insulation layer temperature is less than the dew point temperature, it can be determined that there is a risk of condensation on the radiant surface, and the flow of chilled water can be stopped by turning off the electric heating actuator, allowing for slow heat exchange between the water temperature in the pipes and the insulation layer, thus slowly cooling the room. This effectively prevents indoor condensation while reasonably regulating the indoor environment.

[0091] Alternatively, the room's dew point temperature can be obtained in the following ways:

[0092] The five constant systems obtain the relative humidity of the air in the room.

[0093] The five constant systems determine the dew point temperature of a room based on the relative humidity of the air inside the room.

[0094] In this solution, the relative humidity of the room air can be obtained through a humidity sensor associated with the five constant humidity system, and the dew point temperature of the room can be determined based on the relative humidity. Specifically, the five constant humidity system determines the room dew point temperature based on the relative humidity of the room air, including:

[0095]

[0096] Where Td is the dew point temperature, f is the relative humidity of the room air, a is 7.5, and b is 237.3. This method allows for accurate determination of the dew point temperature by combining the relative humidity of the room air.
