[0003] Currently, existing temperature and humidity control systems typically use ground-source heat pump technology as the heat source and cold source. During cooling, a specific temperature of low-temperature chilled water is supplied to the main unit via a buried pipe system. After heat exchange in the main unit, the water temperature rises to the target temperature, and then dissipates heat through the buried pipe system to cool down to a specific temperature before being recycled. When controlling humidity, chilled water is used to dehumidify the fresh air, lowering its temperature to a certain level. Then, additional electric heating or heat pump reheating equipment is used to raise the supply air temperature to a comfortable level.

Detailed Implementation

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0058] In high-end residences, commercial buildings, hospitals, or laboratories, where indoor environmental comfort is a high priority, temperature and humidity control systems simultaneously meet the needs of dehumidification, temperature regulation, and air quality assurance.

[0059] Currently, existing temperature and humidity control systems typically use ground-source heat pump technology as the heat source and cold source. During cooling, a specific temperature of low-temperature chilled water is supplied to the main unit via a buried pipe system. After heat exchange in the main unit, the water temperature rises to the target temperature, and then dissipates heat through the buried pipe system to cool down to a specific temperature before being recycled. When controlling humidity, chilled water is used to dehumidify the fresh air, lowering its temperature to a certain level. Then, additional electric heating or heat pump reheating equipment is used to raise the supply air temperature to a comfortable level.

[0060] However, existing temperature and humidity control systems rely on separate equipment for temperature and humidity control, resulting in redundancy and wasted resources.

[0061] Considering the aforementioned problems with existing temperature and humidity control systems, this application proposes a temperature and humidity control system that reduces reheating equipment. By reducing reheating equipment, the system complexity is reduced, and energy waste is minimized.

[0062] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0063] Figure 1 This is a schematic diagram of the architecture of a temperature and humidity control system provided in this application. Figure 1 As shown, the temperature and humidity control system includes a ground source heat pump subsystem and a fresh air subsystem. The ground source heat pump subsystem includes a buried pipe and a ground source heat pump unit. The fresh air subsystem includes a fresh air dehumidifier unit and a reheat device. The buried pipe and the reheat device are connected by a first pipeline.

[0064] During the cooling process of the target space based on the temperature and humidity control system, the ground source heat pump unit is used to exchange heat between the target space and the liquid in the buried pipe, thereby cooling down the target space and raising the temperature of the liquid in the buried pipe to a first temperature.

[0065] For example, a ground source heat pump subsystem may be a system that includes buried pipes and a ground source heat pump unit.

[0066] For example, the buried pipe can be a heat exchange pipe buried in the underground soil, which can exchange heat with the soil through a liquid circulating inside the pipe. For example, the buried pipe can be a high-density polyethylene pipe. For example, the ground source heat pump unit can be the core equipment of the ground source heat pump subsystem. For example, the ground source heat pump unit may include a compressor, evaporator, condenser, throttling device, etc.

[0067] For example, the liquid inside the buried pipe can be a medium used to transfer heat. For instance, the liquid inside the buried pipe can be, for example, clean water.

[0068] For example, the target space can be an area that requires temperature and humidity control. For instance, the target space could be a living room in a residential area or an office in an office building.

[0069] For example, the first temperature can be the temperature reached by the liquid in the buried pipe after absorbing heat from the target space during the cooling process. For instance, the initial temperature of the liquid in the buried pipe is 30 degrees Celsius, and the water temperature rises to 35 degrees Celsius after absorbing heat from the target space during cooling, where 35 degrees Celsius is the first temperature.

[0070] Optionally, during the cooling process of the target space, the temperature and humidity control system can obtain heat from the target space through the evaporator in the ground source heat pump unit and transfer this heat to the refrigerant in the ground source heat pump unit. This temperature and humidity control system can be based on the vapor compression cycle principle. The refrigerant in the ground source heat pump unit, carrying heat, exchanges heat with the liquid in the buried pipe in the condenser of the ground source heat pump unit, transferring heat to the liquid in the buried pipe. Then, by reducing the pressure through the throttling device in the ground source heat pump unit, the refrigerant that has lost heat can return to the evaporator in the ground source heat pump unit. In this way, the temperature and humidity control system can lower the temperature of the target space, while simultaneously causing the liquid in the buried pipe to absorb heat and rise to a first temperature.

[0071] The buried pipe is used to transport the liquid at the first temperature to the reheating device through the first pipeline.

[0072] For example, the fresh air subsystem in the temperature and humidity control system may include a fresh air dehumidifier unit and a reheat device.

[0073] For example, the reheating device may be a device for reusing or secondary processing the liquid at the first temperature.

[0074] For example, the first conduit may be a pipe for connecting the buried pipe to the reheating device and for inputting liquid. For example, the first conduit may be a pipe made of high-density polyethylene or a pipe made of stainless steel.

[0075] Optionally, the temperature and humidity control system can be based on a circulating pump to transport the liquid heated to a first temperature in the buried pipe to a reheating device through a first pipeline.

[0076] The fresh air dehumidifier unit is used to dehumidify the gas outside the target space to obtain gas with the target humidity, and then deliver the gas with the target humidity to the reheat device.

[0077] For example, a fresh air dehumidification unit can be an apparatus that includes a fan, dehumidification components, and devices such as filters.

[0078] Optionally, the temperature and humidity control system can dehumidify the air outside the target space using the dehumidification components inside the fresh air dehumidifier unit to obtain air with the target humidity. Then, the temperature and humidity control system can, based on a direct connection duct or a distribution box, use a fan inside the fresh air dehumidifier unit to deliver the air with the target humidity to the reheat device.

[0079] The reheating device is used to heat the gas with the target humidity by passing it through a liquid at the first temperature, so that the gas with the target humidity reaches a preset temperature, and to deliver the gas that meets the preset temperature and the target humidity to the target space.

[0080] In some embodiments, the reheat device may include: a heat exchange tube with a corrugated structure, and a cavity outside the heat exchange tube; the outer wall of the heat exchange tube is provided with a finned heat exchange structure. The buried pipe is specifically used to transport the liquid at the first temperature to the heat exchange tube through the first pipeline. The fresh air dehumidifier unit is specifically used to transport the gas with the target humidity to the cavity.

[0081] For example, a heat exchanger tube with a corrugated structure can be a tubular component with a corrugated tube wall.

[0082] For example, the finned heat exchange structure can be a finned or needle-like protrusion extending from the outer wall of the heat exchange tube.

[0083] Optionally, the temperature and humidity control system can be based on the buried pipe, and a liquid at a first temperature can be transported to the heat exchange tube of the corrugated pipe structure through a first pipeline. The temperature and humidity control system can also use the fresh air dehumidifier unit to transport gas with the target humidity into the cavity.

[0084] Using the above method, the temperature and humidity control system can, based on the buried pipe and through the first pipeline, transport the liquid at the first temperature to the heat exchange tube of the corrugated structure of the reheat device, providing a heat source for subsequent heat exchange. The fresh air dehumidifier unit transports gas with the target humidity to the cavity of the reheat device. This gas flows through the outer wall of the heat exchange tube and the finned heat exchange structure within the reheat device cavity, exchanging heat with the high-temperature liquid inside the heat exchange tube. The corrugated structure of the heat exchange tube within the reheat device, and the finned heat exchange structure on the outer wall of the heat exchange tube, increase the heat exchange area, thereby improving heat exchange efficiency.

[0085] For example, the preset temperature can be a gas temperature value that is pre-set according to the usage requirements of the target space.

[0086] Optionally, the temperature and humidity control system can, based on the reheat device, transfer heat to the gas at the target humidity through heat exchange, based on the temperature difference between the liquid at the first temperature and the gas at the target humidity, so that the gas at the target humidity absorbs heat and its temperature rises to the preset temperature. Then, the reheat device can transport the gas that meets the preset temperature and the target humidity to the target space through conveying equipment such as fans and ducts.

[0087] In this embodiment, the temperature and humidity control system includes a ground source heat pump subsystem and a fresh air subsystem. The ground source heat pump subsystem includes a buried pipe and a ground source heat pump unit. The fresh air subsystem includes a fresh air dehumidifier unit and a reheat device. The buried pipe and the reheat device are connected via a first pipeline. During the cooling process of the target space based on the temperature and humidity control system, the ground source heat pump unit is used to exchange heat between the target space and the liquid in the buried pipe, which can cool the target space and raise the temperature of the liquid in the buried pipe to a first temperature.

[0088] The buried pipe is used to transport the liquid at the first temperature to the reheating device through the first pipeline, laying the foundation for subsequently heating the gas with the target humidity to the preset temperature. The fresh air dehumidifier unit is used to dehumidify the gas outside the target space, obtaining gas with the target humidity, and then transporting this gas to the reheating device. The reheating device is used to heat the gas with the target humidity using the liquid at the first temperature, bringing the gas to the preset temperature, and then transporting the gas meeting the preset temperature and target humidity to the target space. This ensures that the target space receives gas that meets the preset temperature and humidity, thereby reducing system complexity and energy waste.

[0089] Figure 2 A schematic diagram of the architecture of a temperature and humidity control system with a control subsystem provided in this application is shown below. Figure 2 As shown, the temperature and humidity control system may further include a control subsystem. A valve is installed on the first pipeline, and the control subsystem is connected to the valve. The control subsystem can be used to determine a target flow rate of liquid at the first temperature to be delivered to the reheating device based on at least one of the ambient temperature, the current temperature in the target space, the first temperature, and the preset temperature. Then, based on the target flow rate, a target opening degree of the valve is determined. Then, the valve is controlled to the target opening degree so that the liquid at the first temperature with the target flow rate is delivered to the reheating device.

[0090] For example, the control subsystem may be the subsystem in the humidity control system responsible for monitoring, calculating, and executing control commands. For instance, the control subsystem may be an intelligent control system with a temperature sensor.

[0091] For example, the valve may be a component installed on the first pipeline responsible for flow control. For instance, the valve may be an electrically operated regulating valve, etc.

[0092] For example, the target flow rate may be a flow rate value calculated by the control subsystem based on at least one of the ambient temperature, the current temperature in the target space, the first temperature, and the preset temperature.

[0093] For example, the target opening degree can be the degree to which the valve is opened to achieve a target flow rate.

[0094] Optionally, the control subsystem can collect at least one of the following: ambient temperature, current temperature in the target space, first temperature, and preset temperature from the temperature sensor; construct a prompt word; and input the prompt word into a preset model to determine the target flow rate of the liquid delivered to the reheating device at the first temperature. The prompt word can be used to indicate the target flow rate determined based on at least one of the following: ambient temperature, current temperature in the target space, first temperature, and preset temperature.

[0095] It should be understood that the preset model outputs the above-mentioned target flow rate based on at least one of the ambient temperature, the current temperature in the target space, the first temperature, and the preset temperature. For example, it can refer to the training method of any existing deep learning model, which will not be elaborated here.

[0096] Optionally, the control subsystem can determine the target opening of the valve on the first pipeline based on the target flow rate of the liquid delivered to the reheating device at the first temperature. For example, the control subsystem can pre-set a mapping table between the target flow rate and the target valve opening based on the target flow rate, and update the target valve opening by querying the mapping table when the target flow rate changes.

[0097] Optionally, the control subsystem can send control commands to the valve to drive the valve to perform actions, adjust the valve opening to the target opening, and thus transport the liquid at the first temperature at the target flow rate to the reheat device through the first pipeline.

[0098] Using the above method, based on at least one of the ambient temperature, the current temperature within the target space, the first temperature, and the preset temperature, the target flow rate of the liquid at the first temperature delivered to the reheating device can be determined. Based on the target flow rate, the target opening degree of the valve can be determined, ensuring a precise correspondence between the target flow rate and the target opening degree. By controlling the valve to the target opening degree, the liquid at the first temperature and the target flow rate are delivered to the reheating device, achieving dynamic adjustment of heat energy distribution and avoiding energy waste.

[0099] Figure 3 A schematic diagram of the architecture of a temperature and humidity control system with a solar energy storage device provided in this application is shown below. Figure 3 As shown, the temperature and humidity control system may further include a solar energy storage device connected to the reheat device. The control subsystem may also be used to control the solar energy storage device to heat the gas with the target humidity in response to the first temperature being lower than a preset temperature threshold, so that the gas with the target humidity reaches the preset temperature.

[0100] Optionally, the temperature and humidity control system can collect the first temperature of the liquid in the buried pipe in real time and compare it with a preset temperature threshold. If the first temperature is lower than the preset temperature threshold, the control subsystem can send a start command to the solar energy storage device to control the solar energy storage device to heat the gas with the target humidity, so that the gas with the target humidity reaches the preset temperature.

[0101] The following section details how the control subsystem controls the solar energy storage device to heat the gas with the target humidity so that the gas with the target humidity reaches the preset temperature when the first temperature is less than the preset temperature threshold.

[0102] Figure 4 This application provides a schematic diagram of the architecture of a solar energy storage device, as shown below. Figure 4 As shown, the solar energy storage device may include a solar cell, a target switch, and a heating element deployed within the reheat device. The solar cell, the heating element, and the target switch are on a target connection loop. The control subsystem may be used to control the target switch to conduct in response to the first temperature being lower than a preset temperature threshold, thereby opening the target connection loop.

[0103] Then, when the target connection circuit is open, the solar cell can be used to power the heating tube, which is used to heat the liquid at the first temperature to the second temperature. Then, the reheating device can be used to heat the gas with the target humidity using the liquid at the second temperature, so that the gas with the target humidity reaches the preset temperature.

[0104] For example, the target switch can be a switching device used to control whether a target connected circuit is open. For instance, the target switch can be a relay, contactor, etc.

[0105] For example, the target connected loop can be a closed loop formed by the solar cell, the heating tube, and the target switch.

[0106] For example, the liquid at the second temperature can be a liquid that has been heated by the heating tube to a temperature higher than the first temperature.

[0107] Optionally, the control subsystem can send an opening command to the target switch when the first temperature is lower than a preset temperature threshold, thereby closing and connecting the target connection loop. After the target connection loop is closed and connected, the solar cell supplies power to the heating tube, which converts electrical energy into heat energy to heat the liquid at the first temperature, obtaining the liquid at the second temperature. The liquid at the second temperature is then used by the reheating device to heat the gas at the target humidity, obtaining the gas at the target humidity that meets the preset temperature.

[0108] Using the above method, in response to the first temperature being lower than a preset temperature threshold, the control subsystem can control the target switch to turn on, thus opening the target connection loop and laying the foundation for the solar cell to power the heating tube. When the target connection loop is open, the solar cell can power the heating tube, which can heat the liquid at the first temperature to the second temperature. Based on this reheat device, the liquid at the second temperature can heat the gas with the target humidity, obtaining a gas with the target humidity reaching the preset temperature. This achieves multi-heat source coordinated energy supply, thereby improving the stability of the temperature and humidity control system.

[0109] Figure 5 This application provides a schematic diagram of the architecture of a ground source heat pump subsystem, as shown below. Figure 5 As shown, the ground source heat pump subsystem in the temperature and humidity control system may further include a drive unit and a water storage device buried underground. The buried pipe is connected to the water storage device, and the water storage device is connected to the reheat device through the first pipeline. The control subsystem may also control the drive unit to drive the liquid at the first temperature from the buried pipe to the water storage device.

[0110] For example, the water storage device may be a device buried underground for temporarily storing liquid at a first temperature.

[0111] Optionally, the control subsystem can send a control command to the drive device, and in response to the control command, the drive device can transport the liquid at the first temperature from the underground pipe to the water storage device.

[0112] The following is a detailed description of how the control subsystem controls the drive device to transport the liquid at the first temperature from the underground pipe to the water storage device.

[0113] In some embodiments, the control subsystem may acquire historical meteorological data of the geographical location of the target space, and historical cooling load data of the target space. Then, based on the historical meteorological data and the historical cooling load data, it predicts the amount of liquid required to reach the first temperature needed to bring the target humidity to a preset temperature. Then, via the drive device, it controls the amount of liquid at the first temperature delivered from the underground pipe to the water storage device, ensuring that the liquid at the first temperature in the water storage device reaches the predicted amount.

[0114] For example, the historical cooling load data of the target space can be data that reflects the load characteristics of the target space.

[0115] Optionally, the control subsystem can collect historical meteorological data of the geographical location of the target space and historical cooling load data of the target space through a preset interface. For example, the control subsystem can obtain historical meteorological data of the geographical location of the target space and historical cooling load data of the target space through a third-party meteorological database or by reading locally stored historical records.

[0116] Optionally, the control subsystem can construct a prompt word based on the historical meteorological data and the historical cooling load data, and input the prompt word into a machine learning model to predict the predicted amount of liquid required to reach the first temperature needed to achieve the target humidity. The prompt word can be used to indicate the predicted amount of liquid required to reach the first temperature needed to achieve the target humidity based on the historical meteorological data and the historical cooling load data.

[0117] It should be understood that the machine learning model predicts the amount of liquid at the first temperature required to bring the target humidity to the preset temperature based on the historical meteorological data and the historical cooling load data. For example, it can refer to the training method of any existing deep predictive learning model, which will not be elaborated here.

[0118] Optionally, the control subsystem can send control commands to the drive device based on the aforementioned predicted amount, driving the liquid at the first temperature to be transported from the underground pipe to the water storage device. Simultaneously, the control subsystem can collect the storage volume in real time based on the liquid level sensor of the water storage device, and when the storage volume reaches the predicted amount, control the drive device to stop the transport.

[0119] By using the above method, historical meteorological data of the target space's geographical location and historical cooling load data of the target space can be obtained, providing sample data for subsequent predictions. Based on this historical meteorological data and historical cooling load data, the predicted amount of liquid required to reach the preset temperature for the target humidity can be obtained. The driving device controls the amount of liquid at the first temperature transported from the underground pipe to the water storage device, ensuring that the liquid at the first temperature in the water storage device reaches the predicted amount. This achieves precise matching between the water storage device and the predicted demand, improves the stability of the temperature and humidity control system, and thus avoids energy waste.

[0120] This application provides a temperature and humidity control method. The temperature and humidity control system includes: a ground source heat pump subsystem, a fresh air subsystem, and a control subsystem. The ground source heat pump subsystem includes: a buried pipe and a ground source heat pump unit. The fresh air subsystem includes: a fresh air dehumidifier unit and a reheat device. The buried pipe and the reheat device are connected via a first pipeline, and a valve is installed on the first pipeline. The control subsystem is connected to the valve.

[0121] Optionally, during the cooling process of the target space based on the temperature and humidity control system, the ground source heat pump unit is used to exchange heat between the target space and the liquid in the buried pipe, thereby cooling the target space and raising the temperature of the liquid in the buried pipe to a first temperature. The fresh air dehumidifier unit is used to dehumidify the gas outside the target space to obtain gas with the target humidity, and then deliver the gas with the target humidity to the reheat device.

[0122] Figure 6 This is a flowchart illustrating a temperature and humidity control method provided in this application. This temperature and humidity control method is applied to the aforementioned control subsystem. For example... Figure 6 As shown, the temperature and humidity control method may include the following steps:

[0123] S601. Determine the target flow rate of the liquid delivered to the reheating device at the first temperature based on at least one of the ambient temperature, the current temperature in the target space, the first temperature, and a preset temperature.

[0124] S602. Based on the target flow rate, determine the target opening degree of the valve.

[0125] S603. Control the valve to the target opening degree so that the liquid at the first temperature and the target flow rate is delivered to the reheating device through the first pipeline. The reheating device is used to heat the gas with the target humidity using the liquid at the first temperature, so that the gas with the target humidity reaches the preset temperature, and delivers the gas satisfying the preset temperature and the target humidity to the target space.

[0127] Optionally, the application of geothermal energy in fresh air reheat systems can also be seen in utilizing the energy in the buried pipes of a ground source heat pump to provide a heat source for fresh air reheating. For example, this temperature and humidity control system typically includes a ground source heat pump unit, a buried pipe system, and a fresh air dehumidifier system. After the buried water in the buried system exchanges heat with the main unit, the water temperature rises to 35°C, and then, through the reheat coil of the fresh air dehumidifier unit, it provides a heat source for fresh air reheating.

[0128] In this embodiment, the target flow rate of the liquid at the first temperature delivered to the reheating device can be determined based on at least one of the ambient temperature, the current temperature within the target space, the first temperature, and the preset temperature. Based on this target flow rate, the target opening degree of the valve can be determined, ensuring a precise correspondence between the target flow rate and the target opening degree. By controlling the valve to the target opening degree, the liquid at the first temperature and the target flow rate are delivered to the reheating device, achieving dynamic adjustment of heat energy distribution and avoiding energy waste.

The fresh air dehumidifier unit is used to dehumidify the gas outside the target space to obtain gas with the target humidity, and then deliver the gas with the target humidity to the reheat device.
