Description

Technical Field

[0002] With the advancement of modern building technology and the improvement of people's requirements for living environment comfort, radiant air conditioning system has gradually become a mainstream choice in the market as an efficient and comfortable indoor temperature control solution. The radiant air conditioning system transfers cold and heat to the indoor radiant panels through water circulation, thereby adjusting the indoor temperature. The core is to accurately control the water supply temperature to ensure that the system can meet the cooling or heating needs and maximize the use of energy.

[0003] In the related art, radiant air conditioning systems all use the maximum dew point temperature of the whole house as the basis for calculating the water supply temperature in cooling mode. However, due to differences in factors such as the orientation, shading conditions, and personnel activities of different rooms, the dew point temperature distribution is often uneven in actual operation, resulting in the selected maximum value being much higher than the actual demand of most rooms.

[0004] Although the relevant technology can ensure the comfort level under extreme conditions to a certain extent, the selected water supply temperature is too high, which not only prolongs the time to reach the set temperature, but also may not meet the rapid cooling requirements of some rooms.

[0036] Figure 1 is a structural diagram of a radiant air conditioning system provided by an embodiment of the present disclosure; Figure 1As shown, the embodiment of the present disclosure provides a radiation air conditioning system, including: a heat pump host 1, a water collector 2, a water distributor 3 and a radiation heat exchanger 4. The heat pump host 1 is connected to the water distributor 3 through a water outlet pipeline. The radiation air conditioning system distributes the hot water output by the heat pump host 1 to each radiation heat exchanger 4 by adjusting the valve on the water distributor 3. It should be noted that the valve on the water distributor 3 is a manually operated valve and is in a normally open state. Multiple radiation heat exchangers 4 can be set in different rooms in the house to meet the independent temperature control requirements of each room. The water outlet side pipelines of multiple radiation heat exchangers 4 are all connected to the water collector 2. A thermoelectric valve 5 for controlling the water outlet flow rate is provided on the water collector 2. The radiation air conditioning system can adjust the water outlet flow rate of multiple radiation heat exchangers 4 through the thermoelectric valve 5, so that the water outlet flows back to the heat pump host 1 along the water inlet pipeline, thereby forming a complete circulation system. A pressure differential bypass valve 6 is also provided between the water outlet pipeline and the water inlet pipeline of the heat pump host 1. In this way, the performance of the radiation air conditioning system can be effectively optimized by setting a pressure differential bypass valve.

[0037] Optionally, the radiation air conditioning system further includes a fresh air unit, which includes a fresh air dehumidification module 7 and a fresh air outdoor unit 8, and the fresh air dehumidification module 7 is connected to the fresh air outdoor unit 8 through a pipeline. In this solution, by setting up the fresh air unit, the indoor air quality can be effectively improved, and the indoor humidity can be adjusted at the same time to achieve independent control of temperature and humidity.

[0038] Figure 2 is a schematic diagram of a method for controlling a radiant air conditioning system provided by an embodiment of the present disclosure; Figure 2 As shown, the present disclosure embodiment discloses a method for controlling a radiant air conditioning system, comprising:

[0039] S21, the radiation air conditioning system obtains the dew point temperature of each room in the house where the radiation air conditioning system is located.

[0040] S22, the radiant air conditioning system compares the dew point temperatures of the rooms to determine a reference room with the lowest dew point temperature.

[0041] S23, the radiation air conditioning system determines a target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room.

[0042] S24, the radiation air conditioning system controls the radiation air conditioning system to execute the target control strategy.

[0043] In this solution, the radiant air conditioning system can obtain the dew point temperature of each room in the house where the radiant air conditioning system is located in a variety of ways. In one example, if the radiant air conditioning system is associated with a dew point meter, the dew point meter can be used to detect the dew point temperature of each room in the house where the radiant air conditioning system is located. In another example, multiple high-precision temperature and humidity sensors can be arranged at different locations in each room to obtain comprehensive temperature and humidity data. In this way, the radiant air conditioning system can use a multi-point compensation algorithm to calculate the average dew point temperature of each room based on the data of each sensor. With this solution, the dew point temperature can be accurately obtained.

[0044] Furthermore, after obtaining the dew point temperature of each room, the radiant air conditioning system can compare the dew point temperatures of each room to select the reference room with the lowest dew point temperature. For example, if the dew point temperature of room 1 is 13°C, the dew point temperature of room 2 is 15°C, and the dew point temperature of room 3 is 23°C, then room 1 with the lowest dew point temperature can be determined as the reference room. With this solution, the reference room can be accurately determined.

[0045] Further, the radiation air conditioning system determines the target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room, including: the radiation air conditioning system determines the maximum water supply temperature of the heat pump host refrigeration condition. The radiation air conditioning system determines the target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room and the maximum water supply temperature of the heat pump host refrigeration condition. Thus, the radiation air conditioning system can control its execution of the target control strategy. In this way, in the process of executing the target control strategy, the radiation air conditioning system can accurately control the water supply temperature, thereby ensuring that the radiation panel can quickly and effectively reduce the room temperature. In addition, since the radiation air conditioning system formulates the control strategy based on the reference room with the lowest dew point temperature, it can give priority to the room with the most unfavorable humidity and temperature conditions, thereby significantly shortening the time to reach the set temperature. This targeted control method not only meets the rapid cooling requirements of each room, but also ensures the comfort of all rooms in the cooling mode. In addition, since the radiation air conditioning system can monitor and compare the dew point temperature of each room in real time, and dynamically adjust the control strategy according to the actual situation, it can achieve efficient and accurate water supply temperature control. This not only improves cooling efficiency, but also reduces unnecessary energy waste, making the entire air-conditioning system more energy-efficient and environmentally friendly.

[0046] By adopting the method for controlling the radiation air conditioning system provided by the embodiment of the present disclosure, under the premise of ensuring no condensation, the lowest dew point temperature of the whole house is taken as the basis for calculating the system water supply temperature, and the outlet water temperature of the heat pump host is directly controlled, which can not only reduce the water supply temperature and increase the cooling capacity of the radiation heat exchanger, but also simplify the system control logic, and at the same time save the water mixing module and reduce costs. In this way, the time to reach the set temperature can be effectively shortened, the rapid cooling requirements of each room can be met, the comfort of all rooms in the cooling mode can be ensured, and efficient and accurate water supply temperature control can be achieved.

[0047] Figure 3 is a schematic diagram of a method for determining a target control strategy provided by an embodiment of the present disclosure; Figure 3 As shown, optionally, in S23, the radiation air conditioning system determines a target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room, including:

[0048] S31, the radiation air conditioning system determines the maximum water supply temperature of the heat pump host cooling condition.

[0049] S32, the radiation air conditioning system determines a target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room and the maximum water supply temperature of the heat pump host cooling condition.

[0050] In this solution, under cooling conditions, the heat pump host absorbs heat from the room and releases it to the outside through circulation, thereby reducing the indoor temperature. The maximum water supply temperature refers to the maximum cooling water temperature that the heat pump host can provide under cooling conditions. As an example, the maximum water supply temperature of the heat pump host under cooling conditions can be pre-stored in the radiation air conditioning system. It should be noted that the maximum water supply temperature of the radiation air conditioning refrigeration unit is obtained by comprehensively considering the system's cooling efficiency and energy consumption, safety and user comfort, specific environmental conditions and system configuration, as well as theoretical calculations, experimental tests and adjustment optimization. This temperature setting can ensure the efficient and stable operation of the system, reduce energy consumption, avoid condensation risks, and ensure user comfort, and needs to be flexibly adjusted according to the specific unit performance, environmental conditions and the latest technical standards. In actual operation, you can consult professionals for accurate guidance. With this solution, an accurate data basis is provided to achieve the best balance between efficient cooling, energy saving and consumption reduction, and a comfortable environment.

[0051] Furthermore, the radiation air conditioning system can determine the target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room and the maximum water supply temperature of the heat pump host cooling condition. In this scheme, by combining the dew point temperature of the reference room and the maximum water supply temperature of the heat pump host cooling condition, the target control strategy of the radiation air conditioning system is accurately determined to achieve efficient cooling and optimization of the indoor environment.

[0052] Optionally, in S32, the radiation air conditioning system determines a target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room and the maximum water supply temperature of the heat pump host cooling condition, including:

[0053] The radiation air conditioning system determines the first threshold, the second threshold and the third threshold according to the maximum water supply temperature of the heat pump host refrigeration condition.

[0054] When the dew point temperature of the reference room is greater than the first threshold, the radiation air conditioning system determines that the target control strategy of the radiation air conditioning system is to control the radiation air conditioning system to start the fresh air dehumidification module at full power. Or,

[0055] When the dew point temperature of the reference room is greater than the second threshold and less than the first threshold, the radiant air conditioning system determines the target control strategy of the radiant air conditioning system as controlling the radiant air conditioning system to start the heat pump host according to the first target water supply temperature, start the fresh air dehumidification module at full power, and perform interval opening and closing operations on the thermoelectric valves of the water collectors in each room of the house where the radiant air conditioning system is located according to the first time period. Or,

[0056] When the dew point temperature of the reference room is greater than the third threshold and less than the second threshold, the radiant air conditioning system determines that the target control strategy of the radiant air conditioning system is to control the radiant air conditioning system to start the heat pump host according to the first target water supply temperature, start the fresh air dehumidification module at full power, and perform interval opening and closing operations on the thermoelectric valves of the water collectors in each room of the house where the radiant air conditioning system is located according to the second time period. The first time period is longer than the second time period.

[0057] In this solution, the maximum water supply temperature of the heat pump host in the refrigeration condition can be used as the first threshold value C1.

[0058] Optionally, the radiation air conditioning system determines the second threshold value according to the maximum water supply temperature of the heat pump host refrigeration condition, including:

[0059] C2=T1-1

[0060] Among them, C2 is the second threshold value, and T1 is the maximum water supply temperature of the heat pump host cooling condition.

[0061] Optionally, the radiation air conditioning system determines the third threshold value according to the maximum water supply temperature of the heat pump host refrigeration condition, including:

[0062] C3=T1-2

[0063] Among them, C3 is the third threshold value, and T1 is the maximum water supply temperature of the heat pump host cooling condition.

[0064] In this way, the first threshold, the second threshold and the third threshold can be accurately determined in combination with the maximum water supply temperature of the heat pump host cooling condition.

[0065] Optionally, when the dew point temperature of the reference room is greater than the first threshold, the heat pump host remains in a closed state, and only the fresh air dehumidification system is started. The system runs at full power to continuously dehumidify the reference room and other rooms. Among them, other rooms refer to rooms other than the reference room in the house where the radiant air conditioning system is located. With this scheme, not only is efficient dehumidification of the reference room and other rooms achieved, and the increased energy consumption and reduced efficiency that may be caused by the operation of the heat pump host under unfavorable conditions are avoided, but also the effective control of indoor humidity is ensured, the dew point temperature is reduced, and a healthier and more comfortable living environment is provided for users. In addition, the fresh air dehumidification system running at full power also promotes the circulation and renewal of indoor air, further improving the indoor air quality.

[0066] In this solution, the first target water supply temperature can be the dew point temperature of the reference room, and the first time period can be set to 13 minutes. Optionally, when the dew point temperature of the reference room is between the first threshold and the second threshold, the radiant air conditioning system will automatically start the heat pump host and set its water supply temperature to be equal to the current dew point temperature of the reference room. At the same time, the fresh air dehumidification system will also be started, and the air circulation and dehumidification effect will be ensured by running at full power. In addition, the thermoelectric valves of the water collectors in each room of the house where the radiant air conditioning system is located are controlled to operate at intervals according to a predetermined 13-minute cycle, thereby achieving fine adjustment of indoor temperature and humidity. As an example, the thermoelectric valves of the water collectors in each room of the house where the radiant air conditioning system is located are operated at intervals according to a predetermined 13-minute cycle, including: the thermoelectric valves of the water collectors in each room of the house where the radiant air conditioning system is located are controlled to operate at intervals of 7 minutes on and 6 minutes off. With this solution, the working status of the heat pump host and the fresh air dehumidification system can be automatically adjusted within the threshold range according to the dew point temperature of the reference room. At the same time, the periodic opening and closing of the thermoelectric valve of the manifold can be used to effectively control the temperature and humidity of the reference room and other rooms. The target control strategy is selected with the minimum dew point temperature as a reference, which can ensure that the radiant air-conditioning system is intelligently adjusted according to the actual needs of the indoor environment, thereby effectively improving user comfort and maximizing energy utilization, while avoiding potential problems such as condensation.

[0067] In this solution, the first target water supply temperature can be the dew point temperature of the reference room, and the second time period can be set to 10 minutes. Optionally, when the dew point temperature of the reference room is between the third threshold and the second threshold, the radiant air conditioning system will automatically start the heat pump host and set its water supply temperature to be equal to the current dew point temperature of the reference room. The fresh air dehumidification system is turned on at full power to improve the indoor air quality and reduce humidity. In addition, in order to more finely control the temperature and humidity, the thermoelectric valves of the manifolds in the reference room and other rooms are opened at intervals, and each thermoelectric valve is opened and closed in a cycle of 10 minutes, so as to achieve more balanced and efficient temperature and humidity management. As an example, the thermoelectric valves of the manifolds in each room of the house where the radiant air conditioning system is located are opened and closed in a predetermined cycle of 10 minutes, including: the thermoelectric valves of the manifolds in each room of the house where the radiant air conditioning system is located are controlled in intervals according to the start-up period of 5 minutes and the closing period of 5 minutes. With this solution, the heat pump host and the fresh air dehumidification system work together to effectively improve the comfort of the indoor environment, ensuring the appropriate temperature and reducing the humidity, avoiding the discomfort caused by high humidity; on the other hand, the periodic interval opening of the manifold thermoelectric valve not only achieves energy conservation and efficient utilization, but also avoids energy waste caused by continuous opening. In addition, the selection of the target control strategy based on the minimum dew point temperature can ensure that the radiant air conditioning system is intelligently adjusted according to the actual needs of the indoor environment, thereby effectively improving user comfort, maximizing energy utilization, and avoiding the occurrence of potential problems such as condensation.

[0068] Figure 4 is another schematic diagram of a method for determining a target control strategy provided by an embodiment of the present disclosure; Figure 4 As shown, optionally, in S32, the radiation air conditioning system determines a target control strategy of the radiation air conditioning system according to the dew point temperature of the reference room and the maximum water supply temperature of the heat pump host cooling condition, including:

[0069] S41, the radiation air conditioning system determines a third threshold value according to the maximum water supply temperature of the heat pump host cooling condition.

[0070] S42: When the dew point temperature of the reference room is less than a third threshold, the radiant air conditioning system calculates the difference between the dew point temperature of the other rooms and the dew point temperature of the reference room.

[0071] S43, the radiation air conditioning system determines a target control strategy of the radiation air conditioning system according to the difference between the dew point temperature of other rooms and the dew point temperature of the reference room.

[0072] Optionally, the radiation air conditioning system determines the third threshold value according to the maximum water supply temperature of the heat pump host refrigeration condition, including:

[0073] C3=T1-2

[0074] Among them, C3 is the third threshold value, and T1 is the maximum water supply temperature of the heat pump host cooling condition.

[0075] In this way, the third threshold value can be accurately determined in combination with the maximum water supply temperature of the heat pump host cooling condition.

[0076] In this solution, other rooms refer to rooms other than the reference room in the house where the radiation air conditioning system is located. In this way, when the dew point temperature of the reference room is less than the third threshold, the radiation air conditioning system calculates the difference between the dew point temperature of other rooms and the dew point temperature of the reference room. It should be noted that if there is only one other room, the difference between the dew point temperature of the room and the dew point temperature of the reference room can be calculated. If there are multiple other rooms, the difference between the dew point temperature of each other room and the dew point temperature of the reference room can be calculated separately. Furthermore, the radiation air conditioning system can determine the target control strategy of the radiation air conditioning system based on the difference between the dew point temperature of other rooms and the dew point temperature of the reference room. With this solution, more accurate and efficient environmental adjustment can be achieved.

[0077] Optionally, in S43, the radiation air conditioning system determines a target control strategy of the radiation air conditioning system according to the difference between the dew point temperature of other rooms and the dew point temperature of the reference room, including:

[0078] When the difference between the dew point temperature of other rooms and the dew point temperature of the reference room is greater than the fourth threshold, the radiant air conditioning system determines that the target control strategy of the radiant air conditioning system is to control the radiant air conditioning system to start the heat pump host according to the second target water supply temperature, start the fresh air dehumidification module to dehumidify other rooms, start the thermoelectric valve of the reference room water collector, and close the thermoelectric valve of the other room water collector. Or,

[0079] When the difference between the dew point temperature of other rooms and the dew point temperature of the reference room is less than the fourth threshold and greater than the fifth threshold, the radiant air conditioning system determines that the target control strategy of the radiant air conditioning system is to control the radiant air conditioning system to start the heat pump host according to the second target water supply temperature, and at the same time adjust the fresh air dehumidification module so that the air supply volume of other rooms is higher than the air supply volume of the reference room, and start the thermoelectric valve of the water collector of the reference room and perform interval opening and closing operations on the thermoelectric valve of the water collector of other rooms according to the second time period. Or,

[0080] When the difference between the dew point temperature of the other rooms and the dew point temperature of the reference room is less than the fifth threshold value and greater than the sixth threshold value, the radiant air conditioning system determines that the target control strategy of the radiant air conditioning system is to control the radiant air conditioning system to start the heat pump host according to the second target water supply temperature, and at the same time adjust the fresh air dehumidification module so that the air supply volume of the other rooms is higher than the air supply volume of the reference room, and start the thermoelectric valve of the water collector of the reference room and perform interval opening and closing operations on the thermoelectric valve of the water collector of the other rooms according to the third time period. The second time period is longer than the third time period.

[0081] In this scheme, when it is detected that the difference between the dew point temperature of other rooms and the dew point temperature of the reference room exceeds the fourth threshold, the radiation air conditioning system starts the heat pump host and sets the water supply temperature of the heat pump host to the second target water supply temperature to ensure that the system operates under more suitable temperature and humidity conditions. At the same time, the radiation air conditioning system will start the fresh air dehumidification system at full power to dehumidify other rooms. In addition, the water collector thermoelectric valve of the reference room will be opened to keep its temperature and humidity stable, while the water collector thermoelectric valve of other rooms will be closed to avoid unnecessary energy consumption and interference. With this scheme, by accurately judging the difference between the dew point temperature of each room and the reference room, and adjusting the working state of the heat pump host and the power of the fresh air dehumidification system, as well as the switch state of the water collector thermoelectric valve accordingly, the radiation air conditioning system can more intelligently and efficiently realize the independent control and optimization of the temperature and humidity of different rooms, thereby effectively reducing energy consumption while meeting the user's comfort, and improving the operation efficiency and energy utilization of the overall system.

[0082] In this scheme, when it is detected that the difference between the dew point temperature of other rooms and the dew point temperature of the reference room is between the fifth threshold and the fourth threshold, the radiation air conditioning system will start the heat pump host and set the water supply temperature of the heat pump host to the second target water supply temperature. At the same time, the fresh air dehumidification module will also be turned on to effectively reduce the dew point temperature of the reference room and other rooms. In addition, in order to ensure that the dew point temperature of other rooms decreases faster than that of the reference room, the radiation air conditioning system will increase the air supply volume of other rooms. In addition, the water collector thermoelectric valve of the reference room will be opened immediately, while the water collector thermoelectric valve of other rooms will be opened and closed in turn at intervals of one cycle every 10 minutes. With this scheme, by accurately controlling the operating parameters of the heat pump host and the opening of the fresh air dehumidification system, as well as adjusting the air supply volume of different rooms and the switching strategy of the water collector thermoelectric valve, the dew point temperature of the reference room and other rooms can be effectively balanced and reduced, while ensuring that the dehumidification efficiency of other rooms is higher than that of the reference room. This differentiated control strategy not only improves the dehumidification efficiency of the radiant air-conditioning system, but also optimizes energy usage, making the entire radiant air-conditioning system more energy-efficient.

[0083] In this scheme, when the difference between the dew point temperature of other rooms and the dew point temperature of the reference room is between the sixth threshold and the fifth threshold, the radiation air conditioning system will start the heat pump host, set the water supply temperature to the second target water supply temperature, and turn on the fresh air dehumidification system to reduce the dew point temperature of the two rooms. Among them, the air supply volume of other rooms is increased to ensure that their dew point temperature reduction rate is higher than that of the reference room. In addition, the water collector thermoelectric valve of the reference room will be opened immediately, while the water collector thermoelectric valve of other rooms will be opened and closed at intervals of 6 minutes as a cycle. With this scheme, by accurately controlling the operation of the heat pump host, the fresh air dehumidification system and the water collector thermoelectric valve, the dew point temperature of the reference room and other rooms can be efficiently and targetedly reduced, while ensuring that the dehumidification speed of other rooms is faster, thereby optimizing the overall dehumidification effect and improving the energy efficiency of the radiation air conditioning system.

[0084] Optionally, the second target water supply temperature is determined by:

[0085] Radiant air conditioning system obtains temperature correction.

[0086] The radiant air conditioning system uses the sum of the dew point temperature of the reference room and the temperature correction as the second target water supply temperature.

[0087] In this solution, the radiant air conditioning system can pre-store the temperature correction amount according to the actual situation. As an example, the temperature correction amount can be 2°C. Furthermore, the radiant air conditioning system can use the sum of the dew point temperature of the reference room and the temperature correction amount as the second target water supply temperature. For example, if the dew point temperature of the reference room is 24°C, the second target water supply temperature can be determined to be 26°C. With this solution, the second target water supply temperature can be accurately determined.

[0088] Optionally, when the dew point temperature of each room in the house where the radiant air-conditioning system is located is the same, the radiant air-conditioning system determines that the target control strategy of the radiant air-conditioning system is to control the radiant air-conditioning system to start the heat pump host according to the second target water supply temperature, start the fresh air dehumidification module at full power at the same time, start the thermoelectric valve of the reference room water collector, and close the thermoelectric valves of other room water collectors.

[0089] In this scheme, when the dew point temperature of all rooms is the same, it is considered that the indoor humidity environment is at a relatively balanced level. At this time, the heat pump host is started, and the water supply temperature of the heat pump host is set to the second target water supply temperature. At the same time, in order to ensure the efficient operation of the entire air-conditioning system, the water collector thermoelectric valves of the reference room and all other rooms are opened, so that the water flow can be evenly distributed in the system and the stability and consistency of the indoor temperature can be maintained. In addition, in order to further enhance the comfort of the indoor environment and control the humidity, the fresh air dehumidification system is also turned on synchronously. By introducing fresh air that has been dehumidified, the excess indoor moisture is effectively removed to keep the air flowing and fresh. With this scheme, the water supply temperature of the heat pump host and the opening state of the water collector thermoelectric valve can be accurately controlled, so that the air-conditioning system can optimize the energy efficiency while maintaining the indoor temperature uniformity and reduce unnecessary energy consumption. In addition, the introduction and coordination of the fresh air dehumidification module not only effectively maintains the appropriate level of indoor humidity, but also improves the indoor air quality through continuous fresh air supply, providing users with a comfortable and healthy living environment.
