Radiant air conditioning is an air conditioning system based on radiant heat transfer as the main principle to regulate indoor temperature, which can provide a uniform temperature field and has high comfort.

[0003] However, since the main cooling principle of the radiant air conditioning system is heat exchange with air temperature, when the surface temperature of the radiant assembly for radiant heat transfer is lower than the indoor dew point temperature in the case of high indoor humidity or high indoor temperature, water vapor in the air is easy to condense on the surface of the radiant assembly, causing condensation on the surface of the radiant assembly, which affects the cooling efficiency of the air conditioning system.

Both the radiant assembly 130 and the fan assembly 140 are connected to the compressor assembly 110. The processor 170 is electrically connected to the first opening adjustment assembly 150, the second opening adjustment assembly 160, the fan assembly 140, and the radiant assembly 130.

[0051] It is understood that the condenser assembly 110, condenser assembly 120, radiator assembly 130, fan assembly 140, first opening degree adjustment assembly 150, and second opening degree adjustment assembly 160 are connected by pipelines to realize the flow and circulation of refrigerant. The connection between the processor 170 and the first opening degree adjustment assembly 150, second opening degree adjustment assembly 160, fan assembly 140, radiator assembly 130, etc., is an electrical connection to realize the transmission of corresponding electrical signals.

[0052] Specifically, the first end of the compression assembly 110 is connected to the first end of the condenser assembly 120. The second end of the condenser assembly 120 is connected to the first end of the radiant assembly 130 via the first opening adjustment assembly 150.

The second ends of both the radiant assembly 130 and the fan assembly 140 are connected to the second end of the compression assembly 110. The first opening adjustment assembly 150 is used to adjust the opening of the connection channel between the condenser assembly 120 and the radiant assembly 130, and the second opening adjustment assembly 160 is used to adjust the opening of the connection channel between the condenser assembly 120 and the fan assembly 140. The radiant assembly 130 is used to transfer cooling energy into the room via radiation. The fan assembly 140 is used to deliver cool air into the room via forced convection.

[0053] In some embodiments, such as Figure 2 As shown, the radiant convection air conditioning system may also include a temperature and humidity sensor 210, which is connected to the processor 170 and used to collect the dry-bulb temperature and relative humidity of the air in the environment where the radiant convection air conditioning system is located. The specific location of the temperature and humidity sensor 210 is not limited and can be set according to the actual situation.

[0054] In some embodiments, the radiant assembly 130 includes a three-way mixing valve 131, a plate heat exchanger 132, and a radiant coil 133. The inlet of the radiant coil 133 is connected to the outlet of the three-way mixing valve 131, and the outlet of the radiant coil 133 is connected to the first inlet of the three-way mixing valve 131 and the inlet of the plate heat exchanger 132, respectively. The outlet of the plate heat exchanger 132 is connected to the second inlet of the three-way mixing valve 131. The first end of the plate heat exchanger 132 is connected to the first opening adjustment assembly 150, and the second end is connected to the compression assembly 110. The processor 170 is connected to the three-way mixing valve 131.

[0055] In some embodiments, the outlet of the three-way mixing valve 131 is connected to the inlet of the radiant coil 133 via a water pump 134. The water pump 134 is used to pump the water supply from the outlet of the plate heat exchanger 132 and the return water from the outlet of the radiant coil 133 into the inlet of the radiant coil 133, which can improve the water intake efficiency of the radiant coil 133.

[0056] In some embodiments, a temperature sensor 135 is provided at the outlet of the three-way mixing valve 131. The temperature sensor 135 is connected to the processor 170 and is used to detect the outlet water temperature of the three-way mixing valve 131 and transmit the outlet water temperature to the processor. The processor can control the ratio of water supply to the plate heat exchanger 132 and water return to the radiant coil 133 in the three-way mixing valve 131 based on the difference between the outlet water temperature and the dew point temperature, thereby controlling the inlet water temperature of the radiant coil 133.

[0057] In some embodiments, the second end of the condensing assembly 120 is connected to the first opening adjustment assembly 150 and the second opening adjustment assembly 160 via the heating electronic expansion valve 220. When the radiant convection air conditioning system is operating in heating mode, the heating efficiency of the radiant convection air conditioning system can be controlled by controlling the opening of the heating electronic expansion valve 220.

[0058] In some embodiments, the compression assembly 110 includes a compressor 111 and a vapor-liquid separator 112. The first end of the compressor 111 is connected to the first end of the condenser assembly 120, the second end of the fan assembly 140, and the second end of the plate heat exchanger 132 via a first switch. The second end of the compressor 111 is connected to the first end of the vapor-liquid separator 112. The second end of the vapor-liquid separator 112 is connected to the second end of the fan assembly 140, the second end of the plate heat exchanger 132, and the first end of the condenser assembly 120 via a second switch.

[0059] When the radiant convection air conditioning system is operating in cooling mode, the first end of the compressor 111 is connected to the first end of the condenser assembly 120 via a first switch, the connection between the first end of the compressor 111 and the second end of the fan assembly 140 and the second end of the plate heat exchanger 132 is disconnected, the second end of the vapor-liquid separator 112 is connected to the second end of the fan assembly 140 and the second end of the plate heat exchanger 132 via a second switch, and the connection between the second end of the vapor-liquid separator 112 and the first end of the condenser assembly 120 is disconnected. The refrigerant flowing out from the second end of the radiant assembly 130 and the second end of the fan assembly 140 flows into the vapor-liquid separator 112 through the second end of the vapor-liquid separator 112. The vapor-liquid separator 112 separates and stores the unevaporated liquid refrigerant. The vaporized refrigerant flows from the first end of the vapor-liquid separator 112 through the second end of the compressor 111 into the compressor 111. The compressor 111 pressurizes and heats the refrigerant. The pressurized and heated refrigerant flows from the first end of the compressor 111 into the condenser assembly 120. After condensing in the condenser assembly 120, it flows into the first end of the plate heat exchanger 132 through the first opening adjustment assembly 150 and / or into the first end of the fan assembly 140 through the second opening adjustment assembly 160. Finally, the refrigerant flows out through the second end of the radiant assembly 130 and / or the second end of the fan assembly 140 back to the second end of the vapor-liquid separator 112, completing the cycle.

[0060] like Figure 3 As shown, when the radiant convection air conditioning system is operating in heating mode, the first end of the compressor 111 is connected to the second end of the fan assembly 140 and the second end of the plate heat exchanger 132 via a first switch. The connection between the first end of the compressor 111 and the first end of the condenser assembly 120 is disconnected. The second end of the vapor-liquid separator 112 is connected to the first end of the condenser assembly 120 via a second switch. The connection between the second end of the vapor-liquid separator 112 and the second end of the fan assembly 140 and the second end of the plate heat exchanger 132 is disconnected. The refrigerant condensed in the condenser flows from the first end of the condenser into the second end of the vapor-liquid separator 112. The vapor-liquid separator 112 separates and stores the unevaporated liquid refrigerant. The vaporized refrigerant flows from the first end of the vapor-liquid separator 112 into the second end of the compressor 111. The compressor 111 pressurizes and heats the vaporized refrigerant. The pressurized and heated refrigerant flows from the first end of the compressor 111 into the second end of the fan assembly 140 and / or the second end of the plate heat exchanger 132. After flowing through the fan assembly 140 and the plate heat exchanger 132, the refrigerant flows into the second end of the condenser through the first opening adjustment assembly 150 and / or the second opening adjustment assembly 160, completing the cycle.

[0061] Based on the above hardware structure, in an exemplary embodiment, such as Figure 4As shown, a control method for a radiative convection air conditioning system is provided, which can be applied to... Figure 1 Taking processor 170 as an example, the explanation includes steps 402 to 406. Wherein:

[0062] Step 402: When the radiative convection air conditioning system is operating in cooling mode, acquire environmental monitoring parameters.

[0063] Among them, environmental monitoring parameters refer to various data that can reflect the environmental conditions of the radiative convection air conditioning system. For example, environmental monitoring parameters include ambient temperature and ambient humidity.

[0064] In this embodiment, when the radiative convection air conditioning system is in cooling mode, the processor controls the temperature and humidity detector to collect environmental detection parameters in its environment and transmits the environmental detection parameters to the processor, thereby obtaining the environmental detection parameters.

[0065] Step 404: Determine the dew point temperature based on environmental monitoring parameters.

[0066] Dew point temperature refers to the temperature at which the gaseous water in the air must drop to reach saturation and condense into liquid water under a fixed atmospheric pressure. Dew point temperature reflects the absolute moisture content in the air; condensation may occur on the surface of an object when its temperature is below the dew point temperature.

[0067] In this embodiment, after receiving the environmental detection parameters transmitted by the temperature and humidity detector, the processor processes and analyzes the environmental detection parameters using a pre-set calculation model to determine the dew point temperature under the current environment. The calculation model is a mathematical model characterizing the relationship between the environmental detection parameters and the dew point temperature.

[0068] Step 406: When the dew point temperature is greater than the first preset temperature, control the first opening adjustment component and the second opening adjustment component to open, and control the radiation component and the fan component to operate.

[0069] The first preset temperature is a pre-set temperature threshold used for comparison with the dew point temperature. When the dew point temperature exceeds this threshold, it means that there is a risk of condensation in the environment.

[0070] In this embodiment, the processor compares the calculated dew point temperature with a preset first temperature. When the dew point temperature is determined to be greater than the first preset temperature, the processor controls the first opening adjustment component and the second opening adjustment component to open, adjusting the opening of the connection channels between the condensing component and the radiating component, and between the condensing component and the fan component. At the same time, the processor also controls the radiating component and the fan component to start running, so that the radiating component starts to transfer cold energy to the room through radiation, and the fan component starts to deliver cold air to the room through forced convection.

[0071] When the ambient temperature is high and the radiative convection air conditioning system is operating in cooling mode, the fan assembly can help reduce the ambient temperature and humidity, thereby reducing the difference between the surface temperature of the radiative assembly and the dew point temperature. This makes it less likely for water vapor in the air to condense on the surface of the radiative assembly, which helps to reduce the risk of condensation in the radiative convection air conditioning system and improve the cooling efficiency of the air conditioning system.

[0072] In some embodiments, step 406 above, where the dew point temperature is greater than the first preset temperature, involves controlling the first opening adjustment component and the second opening adjustment component to open, including:

[0073] When the dew point temperature is greater than the first preset temperature, the first opening adjustment component is controlled to open at the first opening degree and the second opening adjustment component is controlled to open at the second opening degree according to the dew point temperature.

[0074] Here, the first opening degree refers to the extent to which the first opening degree regulating component is open; the second opening degree refers to the extent to which the second opening degree regulating component is open. The first opening degree and the second opening degree are negatively correlated, while the second opening degree is positively correlated with the dew point temperature.

[0075] In this embodiment, when the processor determines that the dew point temperature is greater than the first preset temperature, it can control the first opening adjustment component to open at a specific first opening degree according to the specific value of the dew point temperature, and at the same time control the second opening adjustment component to open at a specific second opening degree. There is a negative correlation between the first opening degree and the second opening degree, that is, when the first opening degree increases, the second opening degree decreases, and when the first opening degree decreases, the second opening degree increases. Meanwhile, the second opening degree is positively correlated with the dew point temperature, that is, the higher the dew point temperature, the larger the second opening degree.

[0076] In other words, when the higher the dew point temperature, the higher the risk of condensation on the radiant components, increasing the second opening degree and decreasing the first opening degree increases the cooling ratio of the fan components and decreases the cooling ratio of the radiant components, thereby increasing the dehumidification capacity of the fan components. Since the cooling rate of the fan components is greater than that of the radiant components, increasing the cooling ratio of the fan components helps to quickly lower the ambient temperature. Furthermore, because the fan components deliver cool air into the room through forced convection, they can reduce indoor humidity, thus reducing the risk of condensation on the radiant components.

[0077] In this embodiment, the opening degree of the first opening degree adjustment component and the second opening degree adjustment component are precisely controlled according to the dew point temperature, and the opening degree of the two components are specifically related. This allows for more precise adjustment of the cooling capacity distribution. While reducing the risk of condensation in the radiant convection air conditioning system, the ratio of radiant cooling and convective cooling is dynamically adjusted according to the actual dew point temperature, further improving the indoor cooling effect, enhancing the adaptability of the radiant convection air conditioning system to different environmental conditions, and improving the stability and reliability of the radiant convection air conditioning system.

[0078] In some embodiments, after step 404 above, the control method for the radiant convection air conditioning system further includes:

[0079] When the dew point temperature is lower than the second preset temperature, the first opening adjustment component is turned on, and the radiation component is operated.

[0080] The second preset temperature is lower than the first preset temperature. The second preset temperature is a pre-set temperature threshold, and this value is lower than the first preset temperature. When the dew point temperature is lower than the second preset temperature, it means that the temperature in the environment can meet the user's cooling needs, and the radiant components are not prone to condensation.

[0081] In this embodiment, after the processor determines the dew point temperature based on the environmental detection parameters, it compares the dew point temperature with the second preset temperature. If the dew point temperature is found to be lower than the second preset temperature, it means that the risk of condensation on the radiant component is low. The processor then controls the first opening adjustment component to open, adjusts the opening of the connection channel between the condensing component and the radiant component, so that the cold energy can be smoothly transferred to the radiant component. At the same time, it controls the radiant component to start running, transferring the cold energy to the room through radiation to meet the room's cooling needs.

[0082] When cooling, fan units drive airflow to achieve heat exchange. While this provides a fast cooling response, the forced convection can lead to uneven indoor temperature distribution and discomfort from direct airflow onto people, significantly reducing user comfort. Therefore, in radiant convection air conditioning systems, when the dew point temperature is detected to be below the second preset temperature (meaning the ambient temperature already meets the user's cooling needs) and condensation is unlikely to occur on the radiant components, the fan units can be directly shut off, and cooling can be achieved solely through the radiant components. Because radiant components provide a uniform temperature field and are relatively quieter than fan units, the operating noise of the radiant convection air conditioning system can be reduced, thus improving the comfort of cooling.

[0083] In some embodiments, the steps for controlling the operation of the radiation component described above include:

[0084] The opening degree of the first inlet of the three-way mixing valve and the opening degree of the second inlet are controlled according to the dew point temperature.

[0085] Among them, the first inlet opening degree and the second inlet opening degree are negatively correlated. The first inlet opening degree refers to the degree to which the first inlet of the three-way mixing valve is opened, which determines the proportion of return water from the outlet of the radiant coil; the second inlet opening degree refers to the degree to which the second inlet of the three-way mixing valve is opened, which determines the proportion of water supplied from the outlet of the plate heat exchanger.

[0086] In this embodiment, when the processor controls the radiant component to operate, it adjusts the first inlet opening of the first inlet and the second inlet opening of the second inlet of the three-way mixing valve based on the determined dew point temperature. Since the temperature of the return water in the radiant coil is higher than the temperature of the supply water in the plate heat exchanger, changing the opening of these two inlets adjusts the ratio of return water from the radiant coil outlet to supply water from the plate heat exchanger outlet in the mixed water, thereby controlling the inlet water temperature entering the radiant coil and ensuring it operates in a suitable state to achieve good radiant cooling. For example, when the dew point temperature is 5 degrees Celsius lower than the current inlet water temperature of the radiant coil, the proportion of supply water in the plate heat exchanger can be increased, and the proportion of return water in the radiant coil can be decreased, lowering the inlet water temperature of the radiant coil, improving its cooling effect, and thus increasing its cooling efficiency.

[0087] In some embodiments, such as Figure 5 As shown, after step 404 above, the control method for the radiant convection air conditioning system further includes steps 502 to 506. Wherein:

[0088] Step 502: In response to the rapid cooling command, control the second opening adjustment component to open and control the fan component to run.

[0089] Among them, the rapid cooling command is a signal issued by the user or processor based on specific needs, requiring the air conditioning system to quickly reduce the indoor temperature. The rapid cooling command can be output by the user through the remote control device after setting the target temperature, or it can be automatically generated by the processor when it detects a large difference between the user-set target temperature and the current dry-bulb temperature.

[0090] In this embodiment, upon receiving a rapid cooling command, the processor immediately controls the second opening adjustment component to open, adjusting the opening of the connection channel between the condenser component and the fan component, allowing the cooling energy to be smoothly transferred to the fan component. Simultaneously, the processor controls the fan component to start operation, accelerating airflow and rapidly delivering cool air into the room through forced convection, thereby achieving the goal of quickly lowering the indoor temperature.

[0091] Step 504: Determine the temperature difference between the dew point temperature and the target temperature.

[0092] The target temperature is determined based on the rapid cooling command.

[0093] In this embodiment, after receiving the rapid cooling command and determining the target temperature, the processor calculates the difference between the dew point temperature and the target temperature.

[0094] Step 506: When the temperature difference is less than the preset difference threshold, control the first opening adjustment component to open and control the radiation component to operate.

[0095] The preset difference threshold is a pre-set temperature difference standard used to compare the difference between the dew point temperature and the target temperature. When the actual difference is less than the threshold, it means that the indoor temperature is close to the target temperature.

[0096] In this embodiment, after the processor calculates the temperature difference between the dew point temperature and the target temperature, it compares this difference with a preset difference threshold in real time. If the temperature difference is found to be less than the preset difference threshold, the processor controls the first opening adjustment component and the radiation component to open, and the cooling function is achieved through the joint operation of the radiation component and the fan component.

[0097] When rapid cooling is required, the radiant convection air conditioning system first achieves rapid cooling through the fan assembly to lower the dew point temperature. When the dew point temperature drops to near the target temperature, the radiant components are gradually turned on to increase the cooling ratio of the radiant components. This allows the radiant components and the fan assembly to work together to provide cooling, which helps to improve the cooling efficiency of the radiant convection air conditioning system.

[0098] In some embodiments, environmental monitoring parameters include the relative humidity and dry-bulb temperature of the environment in which the radiative convection air conditioning system is located.

[0099] Relative humidity refers to the percentage of water vapor pressure in the air compared to the saturated water vapor pressure at the same temperature, reflecting the humidity of the environment in which a radiative-convective air conditioning system is located. Dry-bulb temperature is a value collected from a dry-bulb thermometer exposed to the air but not directly exposed to sunlight. It is usually considered the actual temperature of the air and is unrelated to humidity.

[0100] In this embodiment, the temperature and humidity detector includes a dry-bulb thermometer and a humidity detector. The dry-bulb temperature and relative humidity in the environment where the radiative convection air conditioning system is located can be detected by the temperature and humidity detector. The dew point temperature can be further calculated based on the dry-bulb temperature and relative humidity.

[0101] Specifically, in one example, since the dew point temperature of a radiant convection air conditioning system is typically greater than 0 degrees Celsius during cooling, a simplified algorithm can be used to calculate the dew point temperature. The formula for calculating the dew point temperature is:

[0102]

[0103] Where Td is the dew point temperature, T is the dry-bulb temperature of the air, and RH is the relative humidity. The error in calculating the dew point temperature using the above formula is approximately ±1℃. Alternatively, other more precise formulas can be used to calculate the dew point temperature, and no further limitations are specified here.

[0104] In an exemplary embodiment, after step 404 described above, the control method for the radiant convection air conditioning system further includes:

[0105] When the dew point temperature is greater than the third preset temperature or the relative humidity is greater than the preset humidity, the second opening adjustment component is turned on, and the fan component is operated.

[0106] Among them, the third preset temperature is greater than the first preset temperature. When the dew point temperature exceeds the third preset temperature, it indicates that the risk of condensation in the environment is high. The preset humidity is a pre-set humidity threshold. When the relative humidity of the environment exceeds the preset humidity, it means that the water vapor content in the air is high and the possibility of condensation increases.

[0107] In this embodiment, after acquiring the dew point temperature and relative humidity determined based on environmental detection parameters, the processor simultaneously performs two condition checks: first, whether the dew point temperature is greater than a third preset temperature; and second, whether the relative humidity is greater than a preset humidity. When either of these conditions is met, the processor controls the second opening adjustment component to open the connection channel between the condenser component and the fan component to an appropriate degree, allowing the cooling energy to be smoothly transferred to the fan component; simultaneously, it controls the fan component to start operation, accelerating the airflow speed and rapidly delivering cool air into the room through forced convection.

[0108] When the dew point temperature is too high or the relative humidity is too high, the risk of condensation in the environment increases significantly. At this time, controlling the second opening adjustment component to open and running the fan component can quickly reduce the indoor temperature and humidity through forced convection, which can reduce the risk of condensation in time and protect the equipment inside the radiant convection air conditioning system from water vapor damage.

[0109] In a specific example, during the operation of the radiative convection air conditioning system, the temperature and humidity detector monitors the dry-bulb temperature and relative humidity of the air in the environment in real time, and transmits the collected dry-bulb temperature and relative humidity to the processor. The processor calculates the current air dew point temperature in real time based on the dry-bulb temperature and relative humidity.

[0110] Upon receiving a user-input nighttime cooling command, the processor activates the first opening adjustment component, enabling the radiant cooling system to operate and providing cooling while simultaneously assessing the current dew point temperature. If the dew point temperature exceeds 12°C, the processor activates the second opening adjustment component, increasing the activation ratio of the first component. This continues until the processor detects that the current dew point temperature is below 12°C, at which point it deactivates the second component, allowing the radiant convection air conditioning system to provide cooling through the radiant components. Simultaneously, the processor controls the three-way mixing valve to maintain the inlet water temperature of the radiant components between (dew point temperature + 1) and (dew point temperature + 2), ensuring radiant cooling at night. This method is quieter and more comfortable than fan-assisted cooling.

[0111] Upon receiving a rapid cooling command from the user, the processor controls the first opening adjustment component to close, the second opening adjustment component to open, and the fan unit to start running for rapid cooling. Simultaneously, the processor acquires the dew point temperature in real time and, based on the temperature difference between the dew point temperature and the user-set target temperature, gradually increases the opening of the first opening adjustment component (for example, gradually increasing the opening ratio of the first opening adjustment component when the indoor temperature is ≤ set temperature + 3℃), and activates the radiant cooling unit, achieving coordinated cooling by the radiant coil and the fan coil unit.

[0112] When the user has not set any additional operating modes and the processor has not received nighttime cooling or rapid cooling commands, the processor controls the radiant cooling unit and the fan coil unit to work together for cooling. The processor distributes the load by controlling the opening ratio of the first and second opening adjustment components; radiant cooling bears part of the cooling load, while the fan coil unit bears all the wet load and part of the cooling load. The processor maintains the indoor air dew point temperature between 12 and 20°C by controlling the opening of the first and second opening adjustment components. When the indoor air dew point temperature is detected to be between 18 and 20°C or the indoor relative humidity is >60%, the processor controls to increase the opening ratio of the second opening adjustment component to accelerate indoor dehumidification. When the indoor air dew point temperature exceeds 20°C, the first opening adjustment component is closed and the second opening adjustment component is fully open, and dehumidification is quickly completed through the fan component. When the processor detects and calculates that the indoor air dew point temperature is below 14°C or the indoor relative humidity is <40%, the processor gradually decreases the opening ratio of the second opening adjustment component and increases the opening ratio of the first opening adjustment component, allowing the radiant cooling to bear more cooling load and achieve higher comfort. When the processor detects and calculates that the indoor air dew point temperature is below 12°C, the processor controls to close the second opening adjustment component, shuts down the fan, and only operates the radiant cooling circuit. The three-way mixing valve is controlled to keep the inlet water temperature of the radiant coil between (dew point temperature + 1°C) and (dew point temperature + 2°C) to ensure safe operation of the radiant cooling.
