Description

Technical Field

[0001] This invention belongs to the field of radiant air conditioning control technology, specifically relating to a method, device, and storage medium for controlling radiant terminal air supply. Background Technology

[0002] Currently, in all-air systems, during summer (especially in humid southern regions), due to the high moisture load, the supply air temperature after dew point dehumidification by the air conditioning unit is generally low, at 12-15℃. Directly delivering this air indoors results in poor comfort. Therefore, a reheat module (usually electrically heated) is often added after dehumidification to increase the supply air temperature and reduce the supply air temperature difference. However, this method also leads to some heat and cold offsetting. In fresh air circulation, especially in 100% fresh air systems, the amount of heat and cold offsetting is large, resulting in energy inefficiency. Therefore, how to balance dehumidification and energy saving, as well as how to improve thermal comfort, are problems that radiant air conditioning systems currently need to address. Summary of the Invention

[0003] This invention provides a radiant terminal air supply control method, device, and storage medium. By eliminating the system reheat module and adopting dew point air supply, the supplied air passes through the air outlet and reaches the inlet of the radiant terminal air supply channel. Then, it passes through the channel formed by the insulation board and the radiant board, reaches the air outlet, and enters the room. It releases cooling capacity into the room in the form of radiant energy conversion, which perfectly compensates for the high humidity load period during system startup and operation. This achieves the purpose of storing the increased cooling capacity due to dehumidification and releasing it slowly, avoiding the cooling and heat cancellation caused by reheating. It takes into account both the thermal comfort of the radiant terminal and improves the system economy, thereby solving the above-mentioned technical problems.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: In a first aspect, the present invention provides a method for controlling air supply at a radiant terminal, wherein the radiant terminal includes an air supply outlet, an air outlet, a radiant plate, and an insulation plate; the radiant plate and the insulation plate are arranged opposite to each other and form an air supply channel, the air supply outlet is located at the front end of the air supply channel, and the air outlet is located at the end of the air supply channel; the radiant plate includes a heat storage layer, a radiant layer, and a microporous channel. The control method includes the following steps: S1: During the start-up phase, the air supply valve remains open and the air outlet valve remains closed during the preset cold storage time. Once the preset cold storage time has been reached, the air outlet valve is opened and the radiant cold storage mode is activated. S2: When the running time is greater than or equal to the preset start time, the start-up phase ends, the opening of the air outlet damper is increased, and the radiant cooling mode is run. S3: When the temperature of the radiant panel is less than or equal to the indoor dew point temperature, increase the dehumidification capacity and reduce the opening of the air outlet damper to run the radiant cold storage mode. S4: When the temperature of the radiant panel is greater than or equal to the sum of the indoor dew point temperature and the preset temperature margin, increase the opening of the air outlet damper and run the cooling mode.

[0005] In some embodiments, in the radiant cold storage mode, the pressure difference between the upper and lower parts of the radiant terminal is a first preset pressure difference; in the radiant cooling mode, the pressure difference between the upper and lower parts of the radiant terminal is a second preset pressure difference; in both the radiant cold storage mode and the radiant cooling mode, the indoor air supply volume is the rated air supply volume.

[0006] In some embodiments, the second preset pressure difference is less than the first preset pressure difference; under the first preset pressure difference, the air volume delivered by the microporous channel is 50% of the rated air volume; under the second preset pressure difference, the air volume delivered by the microporous channel is 30% of the rated air volume.

[0007] In some embodiments, after the start-up phase ends, the surface temperature of the radiant panel, the indoor temperature, and the indoor relative humidity are continuously monitored, and the indoor dew point temperature is calculated based on the indoor temperature and the indoor relative humidity.

[0008] In a second aspect, the present invention provides a computer-readable storage medium, characterized in that it stores an air supply control program for a radiating terminal, which, when executed by a processor, implements the air supply control method for a radiating terminal as described in any of the preceding claims.

[0009] Thirdly, the present invention provides a radiant terminal, including an air supply outlet, an air outlet, a radiant plate, and an insulation plate; the radiant plate and the insulation plate are arranged opposite to each other to form an air supply channel, the air supply outlet is located at the front end of the air supply channel, and the air outlet is located at the end of the air supply channel; the radiant plate includes a heat storage layer, a radiant layer, and a microporous channel.

[0010] Fourthly, the present invention provides a radiant terminal air supply control device. The radiant terminal includes an air supply outlet, an air outlet, a radiant plate, and an insulation plate; the radiant plate and the insulation plate are arranged opposite to each other and form an air supply channel, the air supply outlet is located at the front end of the air supply channel, and the air outlet is located at the end of the air supply channel; the radiant plate includes a heat storage layer, a radiant layer, and a microporous channel; the control device includes: The control module is used to keep the air supply valve open and the air outlet valve closed during the startup phase and the preset cold storage time. When the preset cold storage time is reached, the air outlet valve is opened and the radiant cold storage mode is run. When the running time is greater than or equal to the preset start-up time, the start-up phase ends, the opening of the air outlet damper is increased, and the radiant cooling mode is activated. When the temperature of the radiant panel is less than or equal to the indoor dew point temperature, increase the dehumidification capacity and reduce the opening of the air outlet damper to run the radiant cold storage mode. When the temperature of the radiant panel is greater than or equal to the sum of the indoor dew point temperature and the preset temperature margin, the opening of the air outlet damper is increased and the cooling mode is activated.

[0011] In some embodiments, the control module is further configured to, in the radiant cold storage mode, control the pressure difference between the upper and lower ends of the radiant terminal to a first preset pressure difference; in the radiant cooling mode, control the pressure difference between the upper and lower ends of the radiant terminal to a second preset pressure difference; and in both the radiant cold storage mode and the radiant cooling mode, control the indoor air supply volume to the rated air supply volume.

[0012] In some embodiments, the second preset pressure difference is less than the first preset pressure difference; under the first preset pressure difference, the air volume delivered by the microporous channel is 50% of the rated air volume; under the second preset pressure difference, the air volume delivered by the microporous channel is 30% of the rated air volume.

[0013] In some embodiments, the control module is further configured to continuously monitor the radiant panel temperature, indoor temperature, and indoor relative humidity after the start-up phase ends, and calculate the indoor dew point temperature based on the indoor temperature and indoor relative humidity.

[0014] The beneficial effects of this application are: This application provides a radiant terminal air supply control method, device, storage medium, and system. Through a flow-channel radiant terminal, the system reheat module is eliminated, and dew point air supply is used. After passing through the air outlet, the air reaches the inlet of the radiant terminal flow channel, then passes through a flow channel formed by the insulation board and the radiant board, reaching the air outlet and entering the room. Furthermore, as the air passes over the radiant board, a portion flows into the room through the diffuser holes on the radiant board, thereby reducing the amount of air entering the room from the air outlet and lowering the outlet air velocity. This prevents the supplied air from reaching areas where people are active, creating a draft-free environment. Meanwhile, the radiant panel contains heat storage material. When the airflow passes through, it exchanges heat with the heat storage material, transferring the cooling energy along with the dehumidification to the radiant air supply terminals. This increases the supply air temperature, reduces the supply air temperature difference, and further improves comfort. In addition, the density and size of the micro-perforated channels on the radiant panel can be customized according to the indoor layout, creating different local air supply environments within the same room. In cooler areas, the number of micro-perforations can be increased to improve the vertical airflow in that area, simultaneously increasing both convective and radiative heat transfer. Conversely, in more comfortable areas, the micro-perforation density can be reduced, and the airflow in that area can be appropriately increased to provide a relatively smaller amount of cooling energy. Then, people can choose different office areas according to their personal or work requirements to meet diverse needs. At the same time, the micro-perforated channels can also effectively absorb indoor noise, achieving sound attenuation and creating a quiet and comfortable environment that enhances the user experience. The radiant terminal itself has thermal inertia, releasing cooling capacity into the room in the form of radiant energy conversion. This perfectly compensates for the high humidity load period during system startup and operation, achieving the purpose of storing the increased cooling capacity from dehumidification and releasing it slowly. This avoids the cooling and heat offsetting caused by reheating, thus taking into account both the thermal comfort of the radiant terminal and improving the system's economy.

[0017] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0018] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the described embodiments are only some, not all, of the embodiments of this application. The specific embodiments described herein are merely for explaining this application and are not intended to limit it. All other embodiments obtained by those skilled in the art based on the described embodiments of this application are within the scope of protection of this application.

[0019] It should be noted that in this article, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0020] This solution utilizes a flow-channel radiant air supply terminal, eliminating the system's reheat module and employing dew point air supply. After passing through the air outlet, the air reaches the inlet of the flow channel at the radiant air supply terminal, then flows through a channel formed by the insulation and radiant panels, reaching the outlet and entering the room. Furthermore, as the air passes over the radiant panels, a portion flows into the room through the diffuser holes on the panels, reducing the amount of air entering the room from the outlet and lowering the outlet air velocity. This prevents the air from reaching areas where people are active, creating a draft-free environment. Simultaneously, the radiant panels contain heat storage material. As the airflow passes through, it exchanges heat with the heat storage material, transferring the cooling energy along with dehumidification to the radiant air supply terminal. This increases the supply air temperature, reduces the supply air temperature difference, and further improves comfort. The radiant terminal itself has thermal inertia, releasing cooling capacity into the room in the form of radiant energy conversion. This perfectly compensates for the high humidity load period during system startup and operation, achieving the purpose of storing the increased cooling capacity from dehumidification and releasing it slowly. This avoids the cooling and heat offsetting caused by reheating, thus taking into account both the thermal comfort of the radiant terminal and improving the system's economy.

[0021] A method for controlling radiant terminal air supply, referenced Figure 1 The flowchart of a radiant terminal air supply control method according to this application includes the following steps: S1: During the start-up phase, the air supply valve remains open and the air outlet valve remains closed during the preset cold storage time. Once the preset cold storage time has been reached, the air outlet valve is opened and the radiant cold storage mode is activated. Specifically, before the system starts running, a preset startup time needs to be set. When the system runs within the preset startup time, it is in the startup phase. At the same time, a preset cooling time also needs to be set.

[0022] The preset rated air supply volume Q; the preset pressure difference ΔP1 of the radiant terminal device; when the air supply volume of the microporous channel 20 accounts for 50% of the rated air supply volume (i.e., 0.5Q), the pressure difference between the upper and lower parts of the radiant terminal is ΔP1; the preset pressure difference ΔP2 of the radiant terminal device (ΔP2<ΔP1); when the air supply volume of the microporous channel 20 accounts for 30% of the rated air supply volume (i.e., 0.3Q), the pressure difference between the upper and lower parts of the air supply radiant terminal is ΔP2. The preset air outlet 2 has an air volume of 0.5Q when the pressure difference between the upper and lower ends of the air supply and radiation terminal is △P1, and an air volume of 0.7Q when the pressure difference between the upper and lower ends of the air supply and radiation terminal is △P2.

[0023] During the startup phase, the electric air valve of air outlet 1 is fully opened and the electric air valve of air outlet 2 is fully closed within the preset cold storage time. In this scheme, the preset cold storage time can be set to 3-5 minutes. Since the initial air supply temperature is low, it runs for 3-5 minutes under this condition to ensure that the dehumidified air is delivered to the air supply and radiation terminal as soon as possible, thereby reducing the dew point temperature of the nearby air and pushing the hot and humid air away from the radiation surface area to ensure that no condensation occurs on the radiation plate surface. At this time, since air outlet 2 is fully closed, the air supply and radiation terminal air supply resistance increases, and the unit operates at a volume less than the rated air volume Q, resulting in more thorough surface dehumidification, which is conducive to ensuring the initial air supply dehumidification volume.

[0024] After the cold storage is completed, the electric air valve of air outlet 2 is opened, and air outlet 2 starts to supply air. Then, the pressure difference ΔP of the radiant air supply terminal device is made equal to the preset value ΔP1, and the entire room is supplied with air at the rated air volume Q (50% air supply radiant terminal + 50% air outlet 2), and the convection air supply, radiant terminal air supply + radiant cold storage mode is executed.

[0025] S2: When the running time is greater than or equal to the preset start time, the start-up phase ends, the opening of the air outlet damper is increased, and the radiant cooling mode is run. Specifically, when the system running time is detected to be greater than or equal to the preset start time, the start-up phase ends and the system switches to normal operation. The opening of the electric air valve at air outlet 2 is increased so that the pressure difference ΔP of the radiant air supply terminal device is equal to the preset value ΔP2. The entire room is still supplied with air at the rated air volume Q (30% of the air supply radiant terminal + 70% of the air outlet 2), and the system operates in convection air supply, radiant terminal air supply + radiant cooling mode.

[0026] S3: When the temperature of the radiant panel is less than or equal to the indoor dew point temperature, increase the dehumidification capacity and reduce the opening of the air outlet damper to run the radiant cold storage mode. Specifically, during normal operation, the radiant panel temperature, indoor temperature, and indoor relative humidity are continuously monitored. The indoor dew point temperature is calculated based on the measured indoor temperature and relative humidity and compared with the temperature of the radiant terminal unit. When the radiant panel temperature is less than or equal to the indoor dew point temperature, the dehumidification capacity of the front-end dehumidifier unit is increased. Due to the use of dew point dehumidification, the outlet air temperature is further reduced. The electric damper of outlet 2 is adjusted to make the pressure difference ΔP of the radiant air supply terminal device equal to the preset value ΔP1. The entire room is supplied with air at the rated air volume Q (50% of the radiant air supply terminal + 50% of outlet 2), and the convection air supply, radiant terminal air supply + radiant cold storage mode is implemented.

[0027] S4: When the temperature of the radiant panel is greater than or equal to the sum of the indoor dew point temperature and the preset temperature margin, increase the opening of the air outlet damper and run the cooling mode. Specifically, the preset temperature margin △T1 is the margin for controlling condensation risk. The setting range is 0.5-3℃, which can be adjusted according to the actual situation. If the condensation risk is high, it can be set larger, and if the condensation risk is low, it can be set smaller. The preset temperature margin △T2 is the control hysteresis. It is recommended to set it in the range of 0.5-2℃ to avoid frequent control actions of the system. When the temperature of the radiant panel is detected to be greater than or equal to the sum of the indoor dew point temperature and the preset temperature margin, the opening of the electric damper of the air outlet 2 is increased so that the pressure difference ΔP of the radiant air supply terminal device is equal to the preset value ΔP2. The entire room is still supplied with air at the rated air volume Q (30% air supply radiant terminal + 70% air outlet 2), and the convection air supply, radiant terminal air supply + radiant cooling mode is executed.

[0028] In addition, when no air supply is needed indoors, the electric air valves of air supply outlet 1 and air outlet 2 are closed in sequence to stop the air supply to the room. The air supply radiant terminal can continue to provide radiant cooling to the room for a period of time to offset the residual heat after the room is used, thereby reducing the initial cooling load of the room when it is turned on again.

[0029] In some embodiments, in the radiant cold storage mode, the pressure difference between the upper and lower parts of the radiant terminal is a first preset pressure difference; in the radiant cooling mode, the pressure difference between the upper and lower parts of the radiant terminal is a second preset pressure difference; in both the radiant cold storage mode and the radiant cooling mode, the indoor air supply volume is the rated air supply volume.

[0030] In some embodiments, the second preset pressure difference is less than the first preset pressure difference; under the first preset pressure difference, the air volume delivered by the microporous channel is 50% of the rated air volume; under the second preset pressure difference, the air volume delivered by the microporous channel is 30% of the rated air volume.

[0031] Specifically, this solution has different control and adjustment for the air valve of air outlet 2 during the start-up and normal operation phases. However, in the system's radiant cold storage mode, the pressure difference between the upper and lower parts of the radiant terminal is always controlled to the first preset pressure difference; in the radiant cooling mode, the pressure difference between the upper and lower parts of the radiant terminal is the second preset pressure difference; and in both the radiant cold storage mode and the radiant cooling mode, the indoor air supply volume is the rated air supply volume.

[0032] In some embodiments, after the start-up phase ends, the surface temperature of the radiant panel, the indoor temperature, and the indoor relative humidity are continuously monitored, and the indoor dew point temperature is calculated based on the indoor temperature and the indoor relative humidity.

[0033] Specifically, during normal system operation, the radiant panel temperature, indoor temperature, and indoor relative humidity are continuously monitored. The indoor dew point temperature is calculated based on the indoor temperature and indoor relative humidity, and the air valve can be adjusted by comparing the indoor dew point temperature with the radiant panel temperature.

[0034] A second aspect of the present invention provides a computer-readable storage medium having a radiant terminal air supply control program stored thereon, which, when executed by a processor, implements the radiant terminal air supply control method as described above.

[0035] refer to Figure 2 as well as Figure 3 The third aspect of the present invention provides a radiant terminal, including an air inlet 1, an air outlet 2, a radiant plate 11, and an insulation plate 10; the radiant plate 11 and the insulation plate 10 are arranged opposite to each other and form an air supply channel, the air inlet 1 is located at the front end of the air supply channel, and the air outlet 2 is located at the end of the air supply channel; the radiant plate 11 includes a heat storage layer 21, a radiant layer 22, and a microporous channel 20.

[0036] Specifically, the form of the air supply outlet 1, air outlet 2, and return air outlet 3 in the air supply and radiant terminal of this solution is not limited to... Figure 2 The top-to-bottom airflow configuration can also be configured into various airflow layouts, such as top-to-bottom airflow, top-to-side airflow, and top-to-corner airflow, depending on actual needs. The radiant plate 11 is made of a two-in-one material, such as... Figure 3As shown, the system includes a microporous channel 20, a heat storage layer 21, and a radiation layer 22. The upper layer is a heat storage material, and the lower layer is a hydrophobic radiation surface with a high emissivity. At the beginning of system startup or when the temperature of the radiation panel is detected to be lower than the indoor dew point temperature, the dehumidification load is high, and the outlet air temperature is low. When the dew point air reaches the terminal, the air valve at the air outlet 1 is closed, and a portion of the airflow is sent into the room through the microporous channel 20. Simultaneously, it exchanges heat with the heat storage layer 21, storing the increased cooling capacity from dew point dehumidification in the heat storage layer 21. This cooling capacity is then transferred to the radiation layer 22 for cooling. The lower surface of the radiation layer 22 is coated with a high emissivity hydrophobic material, continuously providing radiant cooling to the room. Simultaneously, it acts as a thermal resistance layer, increasing the supply air temperature reaching the room. Without activating the reheat module, the increased cooling capacity from dew point dehumidification is stored at the radiant air supply terminal and then reused indoors, thus eliminating energy waste caused by heat loss during reheat operation.

[0037] Furthermore, while conventional radiant cooling systems offer high comfort, they still carry the risk of surface condensation. This solution addresses this risk by increasing the system's dehumidification capacity and simultaneously increasing the airflow through the microporous channels 20. This regional airflow continuously delivers dehumidified dry air to the radiant surface, lowering the dew point temperature near the radiant terminals and pushing hot, humid air away from the radiant surface area. This ensures no condensation occurs on the radiant panels without affecting the system's efficient radiant heat exchange. At this point, the microporous channels 20 serve as the main air outlet, and the upward airflow combined with the natural downward flow of cold air creates displacement ventilation, rapidly reducing the indoor temperature while avoiding discomfort caused by the disturbance of low-temperature airflow. This approach maintains high comfort while preventing condensation.

[0038] It is worth mentioning that the micro-perforated flow channel 20 can be configured with different perforation densities and sizes according to different indoor scenarios. For example, in areas with high heat loads, the perforation density of the radiant terminals can be increased to improve the airflow in that area. Compared to the radiant terminals in the surrounding areas, it can still provide cooling to that area through surface radiation heat exchange.

[0039] A fourth aspect of the present invention provides a radiant terminal air supply control device. The radiant terminal includes an air inlet, an air outlet, a radiant plate, and an insulation plate; the radiant plate and the insulation plate are arranged opposite to each other and form an air supply channel, the air inlet is located at the front end of the air supply channel, and the air outlet is located at the end of the air supply channel; the radiant plate includes a heat storage layer, a radiant layer, and a microporous channel; the control device includes: The control module is used to keep the air supply valve open and the air outlet valve closed during the startup phase and the preset cold storage time. When the preset cold storage time is reached, the air outlet valve is opened and the radiant cold storage mode is run. When the running time is greater than or equal to the preset start-up time, the start-up phase ends, the opening of the air outlet damper is increased, and the radiant cooling mode is activated. When the temperature of the radiant panel is less than or equal to the indoor dew point temperature, increase the dehumidification capacity and reduce the opening of the air outlet damper to run the radiant cold storage mode. When the temperature of the radiant panel is greater than or equal to the sum of the indoor dew point temperature and the preset temperature margin, the opening of the air outlet damper is increased and the cooling mode is activated.

[0040] In some embodiments, the control module is further configured to, in the radiant cold storage mode, control the pressure difference between the upper and lower ends of the radiant terminal to a first preset pressure difference; in the radiant cooling mode, control the pressure difference between the upper and lower ends of the radiant terminal to a second preset pressure difference; and in both the radiant cold storage mode and the radiant cooling mode, control the indoor air supply volume to the rated air supply volume.

[0041] In some embodiments, the second preset pressure difference is less than the first preset pressure difference; under the first preset pressure difference, the air volume delivered by the microporous channel is 50% of the rated air volume; under the second preset pressure difference, the air volume delivered by the microporous channel is 30% of the rated air volume.

[0042] In some embodiments, the control module is further configured to continuously monitor the radiant panel temperature, indoor temperature, and indoor relative humidity after the start-up phase ends, and calculate the indoor dew point temperature based on the indoor temperature and indoor relative humidity.
