Description

Technical Field

[0001] This application relates to the field of temperature control, and more particularly to a temperature control method and related equipment. Background Technology

[0002] Some equipment has specific temperature requirements. Excessive or insufficient temperature can negatively impact performance and lifespan, necessitating temperature control. For equipment used indoors, temperature control devices can regulate the ambient temperature, allowing for temperature control of multiple devices within the same space.

[0003] However, since multiple devices within the same space have different temperature requirements, to meet the temperature control requirements of all devices, the indoor temperature can only be adjusted based on the most stringent temperature requirement among them. This results in redundancy in temperature control for other devices in the space. Furthermore, the temperature control equipment consumes more energy to meet the most stringent temperature requirement, leading to energy waste.

[0004] For example, if cooling is required, and device A in the space requires a temperature of 20°C, while device B in the same space requires a temperature of 25°C, then in order to meet the temperature requirement of device A, the indoor temperature needs to be lowered to 20°C. For device B, the ambient temperature is 5°C lower than the required temperature, and the temperature control equipment wastes energy to cool the space near device B from 25°C to 20°C. Summary of the Invention

[0005] This application provides a temperature control method and related equipment for precise temperature control of equipment with higher temperature control requirements within the same space, reducing temperature control redundancy for other equipment within the space, thereby reducing temperature control power consumption.

[0006] A first aspect of this application provides a temperature control method, which is applied to a cold storage temperature control device in a target space. The target space also contains a main temperature control device and a controlled temperature device. The method includes:

[0007] When the cooling temperature of the main temperature control device is not higher than the first preset temperature, the cold storage temperature control device stores cold; when the cooling temperature of the main temperature control device is not lower than the second preset temperature, the cold storage temperature control device releases cold to the controlled temperature device, wherein the second preset temperature is higher than the first preset temperature.

[0008] In this embodiment, when cooling the controlled temperature device, the cold storage temperature control device stores cold energy when the main temperature control device's cooling temperature is low; when the main temperature control device's cooling temperature is high, the cold storage temperature control device releases the stored cold energy to the controlled temperature device. This allows the controlled temperature device to maintain a lower temperature when the main temperature control device's cooling temperature is high, thus meeting the device's required temperature. Through reasonable regulation of the cold energy, the main temperature control device can meet the temperature requirements of all devices in the target space at a higher cooling temperature, saving energy consumption.

[0009] In one alternative implementation, the target space is a communication equipment room, and the temperature-controlled device is a communication device.

[0010] In one alternative implementation, the target space is a server room, and the temperature-controlled device is a server.

[0011] In one alternative implementation, the cold storage temperature control device stores cold during off-peak electricity consumption periods and releases cold to the controlled equipment during peak electricity consumption periods.

[0012] In this embodiment, by storing cold during off-peak hours and releasing it during peak hours, the main temperature control device can achieve higher cooling temperatures to control the temperature of equipment in the target space during peak hours. This saves power consumption of the main temperature control device during peak hours and reduces the power supply pressure during peak periods. Essentially, it uses electricity from off-peak hours to cool the controlled equipment during peak hours, balancing power consumption between peak and off-peak periods from the perspective of the overall power grid, achieving reasonable power consumption regulation. Furthermore, since the unit price of electricity is higher during peak hours, saving power consumption of the main temperature control device during peak hours also saves on temperature control costs.

[0013] In one alternative implementation, after the cold energy stored in the cold storage and temperature control device has been released, the cold storage and temperature control device can cool down the controlled equipment.

[0014] In this embodiment, after the cold energy stored in the cold storage temperature control device is released, the cold storage temperature control device cools the controlled device through refrigeration, so that the main temperature control device does not need to lower its refrigeration temperature to meet the temperature requirements of the controlled device. The refrigeration of the cold storage temperature control device is only used to cool the controlled device, with a smaller cooling range and lower energy consumption; the refrigeration of the main temperature control device is used to lower the overall temperature of the target space environment, with a larger cooling range and higher energy consumption. Therefore, to meet the temperature requirements of the controlled device, the cold storage temperature control device uses refrigeration, which lowers the refrigeration temperature compared to the main temperature control device, thus saving energy.

[0015] In one optional implementation, the cold storage and temperature control device can store or release cold according to the instructions of the control device. Specifically, in this method, before the cold storage and temperature control device stores cold, it receives a first signal from the control device, which instructs the cold storage and temperature control device to store cold; before the cold storage and temperature control device releases cold to the controlled device, it receives a second signal from the temperature control device, which instructs the cold storage and temperature control device to release cold to the controlled device.

[0016] In this embodiment, the cold storage and temperature control device stores or releases cold according to the instructions of the control device. The control device can also be used to manage the cooling of the main temperature control device, thereby comprehensively considering various factors in the target space, scheduling the main temperature control device and the cold storage and temperature control device, achieving precise temperature control in the target space, and reducing the energy consumption and cost required to control the temperature of the equipment in the target space.

[0017] In one optional implementation, the cold storage temperature control device can be used not only for cold storage and release but also for heat storage and release. In this method, a secondary temperature control device is also present within the target space, and this secondary temperature control device is used for heating. When the heating temperature of the secondary temperature control device is not lower than a third preset temperature, the cold storage temperature control device stores heat; when the heating temperature of the secondary temperature control device is not higher than a fourth preset temperature, the cold storage temperature control device releases heat to the controlled equipment; wherein the fourth preset temperature is lower than the third preset temperature.

[0018] In the embodiments of this application, heating is also referred to as heating supply, and is not limited here.

[0019] In this embodiment, when heating the controlled temperature device, the cold storage temperature control device stores heat when the auxiliary temperature control device's heating temperature is high; when the auxiliary temperature control device's cooling temperature is low, the cold storage temperature control device releases the stored heat to the controlled temperature device. This allows the controlled temperature device to maintain a higher temperature when the auxiliary temperature control device's heating temperature is low, meeting the device's required temperature. Through reasonable heat regulation, the auxiliary temperature control device can meet the temperature requirements of all devices in the target space at a lower heating temperature, saving energy consumption.

[0020] In one alternative implementation, the cold storage temperature control device stores heat during off-peak electricity consumption periods and releases heat to the controlled equipment during peak electricity consumption periods.

[0021] In this embodiment, by storing heat during off-peak hours and releasing it during peak hours, the secondary temperature control device can achieve temperature control of the equipment in the target space at a lower heating temperature during peak hours. This saves power consumption of the secondary temperature control device during peak hours, reducing the power supply pressure during peak periods. Essentially, it uses electricity from off-peak hours to heat the controlled equipment during peak hours, balancing power consumption between peak and off-peak periods from the perspective of the overall power grid, achieving reasonable power regulation. Furthermore, since the unit price of electricity is higher during peak hours, saving power consumption of the primary temperature control device during peak hours also reduces temperature control costs.

[0022] In one alternative implementation, after the heat stored in the cold storage temperature control device has been released, the cold storage temperature control device can generate heat to raise the temperature of the controlled device.

[0023] In this application, after the heat stored in the cold storage temperature control device is released, the cold storage temperature control device heats the controlled equipment by generating heat, so that the secondary temperature control device does not need to increase its heating temperature to meet the temperature requirements of the controlled equipment. The heating of the cold storage temperature control device is only used to heat the controlled equipment, with a small heating range and low energy consumption; the heating of the secondary temperature control device is used to raise the overall temperature of the target space environment, with a large heating range and high energy consumption. Therefore, to meet the temperature requirements of the controlled equipment, the cold storage temperature control device generates heat, which saves energy compared to the secondary temperature control device increasing its heating temperature.

[0024] In one optional implementation, the cold storage temperature control device can store or release heat according to the instructions of the control device. Specifically, in this method, before the cold storage temperature control device stores heat, it receives a third signal from the control device, which instructs the cold storage temperature control device to store heat; before the cold storage temperature control device releases heat to the controlled device, it receives a fourth signal from the temperature control device, which instructs the cold storage temperature control device to release heat to the controlled device.

[0025] In this embodiment, the cold storage temperature control device stores or releases heat according to the instructions of the control device. The control device can also be used to manage the heating of the secondary temperature control device, thereby comprehensively considering various factors in the target space, scheduling the secondary temperature control device and the cold storage temperature control device, achieving precise temperature control in the target space, and reducing the energy consumption and cost required to control the temperature of the equipment in the target space.

[0026] In one alternative implementation, the control signals sent by the control device to the cold storage temperature control device, such as the first signal, the second signal, the third signal, and the fourth signal, are determined by the control device based on at least one of the following: peak electricity consumption period (in the area where the main temperature control device is located), weather, the traffic volume of the controlled temperature device, the actual temperature of the controlled temperature device, and the temperature requirement of the controlled temperature device.

[0027] In this embodiment, the control device determines the operating state (cold storage, cold release, heat storage, heat release) of the cold storage temperature control equipment based on factors such as peak electricity consumption times and weather conditions, and can rationally plan the switching of the operating state of the cold storage temperature control equipment. For example, if the weather forecast indicates that high temperatures will continue in the future, the same amount of cold energy will be released more quickly. In this case, the cold storage time can be extended to increase the amount of cold energy stored, so as to extend the cold release time as much as possible under high temperature conditions.

[0028] In one alternative implementation, the main temperature control device and the cold storage temperature control device are connected by a heat pipe. The cold storage temperature control device exchanges heat with the main temperature control device through the heat pipe, thereby storing the cold energy from the main temperature control device.

[0029] In this embodiment, a heat pipe connects the main temperature control device and the cold storage temperature control device. Compared to direct heat exchange through air, the heat pipe improves the energy transfer efficiency of heat exchange, thereby reducing energy waste. When the main temperature control device cools at a low temperature for the same duration, the cold storage capacity of the cold storage temperature control device can be increased, extending the cold release time of the cold storage temperature control device to the controlled device. Conversely, when the main temperature control device cools at the same low temperature, the cooling time of the main temperature control device can be reduced. This reduces energy consumption.

[0030] In this embodiment, the cold storage temperature control device can not only store cold energy from the main temperature control device through heat pipes, thereby improving energy transfer efficiency and reducing energy waste in cooling scenarios, but also store heat energy from the secondary temperature control device through heat pipes, thereby improving energy transfer efficiency and reducing energy waste in heating scenarios. For the beneficial effects in heating scenarios, please refer to the above description of the beneficial effects in cooling scenarios, which will not be repeated here.

[0031] In one alternative embodiment, the main temperature control device and the secondary temperature control device are the same device. For example, the main temperature control device can be an air conditioner.

[0032] In one alternative implementation, the main temperature control device can be an air conditioner, and the secondary temperature control device can be a heater.

[0033] A second aspect of this application provides a temperature control method, the method comprising:

[0034] The control device controls the cooling temperature of the main temperature control device to be no higher than a first preset temperature, and transmits a first signal to the cold storage temperature control device, the first signal being used to instruct the cold storage temperature control device to store cold; wherein, both the main temperature control device and the cold storage temperature control device are within the target space; the control device controls the cooling temperature of the main temperature control device to be no lower than a second preset temperature, and transmits a second signal to the cold storage temperature control device, the second signal being used to instruct the cold storage temperature control device to release cold to the controlled temperature device; wherein, the second preset temperature is higher than the first preset temperature.

[0035] The beneficial effects of the second aspect of the embodiments of this application are the same as those of the first aspect, and will not be repeated here.

[0036] In one alternative implementation, the target space is a communication equipment room, and the temperature-controlled device is a communication device.

[0037] In one alternative implementation, the target space is a server room, and the temperature-controlled device is a server.

[0038] In one optional implementation, a secondary temperature control device is also present within the target space, and the control device is used to control the heating within the target space. Specifically, in this method, the control device controls the heating temperature of the secondary temperature control device to be no lower than a third preset temperature, and transmits a third signal to the cold storage temperature control device, the third signal being used to instruct the cold storage temperature control device to store heat; the control device controls the heating temperature of the secondary temperature control device to be no higher than a fourth preset temperature, and transmits a fourth signal to the cold storage temperature control device, the fourth signal instructing the cold storage temperature control device to release heat to the controlled temperature device; wherein, the fourth preset temperature is lower than the third preset temperature.

[0039] In one optional implementation, during off-peak electricity consumption periods, the control device controls the cooling temperature of the main temperature control device to be no higher than a first preset temperature and transmits a first signal to the cold storage temperature control device; during peak electricity consumption periods, the control device controls the cooling temperature of the main temperature control device to be no lower than a second preset temperature and transmits a second signal to the cold storage temperature control device.

[0040] In one optional implementation, a secondary temperature control device is also present in the target space. The control device controls the heating temperature of the secondary temperature control device to be no lower than a third preset temperature and transmits a third signal to the cold storage temperature control device. The third signal is used to instruct the cold storage temperature control device to store heat. The control device controls the heating temperature of the secondary temperature control device to be no higher than a fourth preset temperature and transmits a fourth signal to the cold storage temperature control device. The fourth signal instructs the cold storage temperature control device to release heat to the controlled temperature device.

[0041] In one alternative implementation, the control signals sent by the control device to the cold storage temperature control device, such as the first signal, the second signal, the third signal, and the fourth signal, are determined by the control device based on at least one of the following: peak electricity consumption time (in the area where the main temperature control device is located), weather, the traffic volume of the controlled temperature device, the actual temperature of the controlled temperature device, and the temperature requirement of the controlled temperature device.

[0064] This application provides a temperature control method and related equipment for precise temperature control of equipment with higher temperature control requirements within the same space, reducing temperature control redundancy for other equipment within the space, thereby reducing temperature control power consumption.

[0065] In the field of communications, communication equipment enables functions such as data transmission. Because these devices have temperature requirements, excessively high or low temperatures can affect their performance and lifespan; therefore, temperature control is necessary. For indoor equipment, the ambient temperature can be controlled by a main temperature controller, thereby controlling the temperature of the indoor equipment.

[0066] Multiple devices in the same space may have different temperature requirements. To meet the temperature requirements of all devices, the indoor temperature needs to be adjusted based on the most stringent requirement among them. However, there is redundancy in temperature control for other devices in the space. Furthermore, the temperature control equipment consumes more energy to meet the most demanding requirement, resulting in energy waste.

[0067] For example, such as Figure 1 As shown, in a communication equipment room, air conditioning is used to cool multiple devices. Device B has the most stringent temperature requirement, needing a temperature of 25℃. To meet device B's temperature requirement, the air conditioning is set to 25℃. However, other devices in the equipment room do not require such a low temperature, resulting in redundant cooling for these other devices.

[0068] Since the embodiments of this application mainly consider the control of temperature, the influence of temperature is mainly considered in the embodiments of this application. The temperature requirements of the equipment can also be referred to as demand or required temperature, which is not limited here.

[0069] Furthermore, because air conditioning operates on a single-point cooling system, it cannot achieve a completely uniform indoor temperature. The closer you are to the air conditioner, the lower the temperature; conversely, the farther away you are, the higher the temperature. For example... Figure 1 As shown in the diagram, among the multiple devices, device D, which is closer to the air conditioner, has a lower actual temperature of 23℃; while device B, which is furthest from the air conditioner, has an actual temperature of 27-30℃. Therefore, the cooling effect on device B is insufficient and cannot meet its cooling needs. Insufficient cooling for devices far from the air conditioner will affect their performance and lifespan.

[0070] To address the aforementioned shortcomings, this application proposes a temperature control method and related equipment. Through a cold storage temperature control device, precise single-point temperature control can be achieved for equipment with high temperature control requirements within a space. This allows the main temperature control device to meet the lower temperature control needs of other equipment with lower power consumption, while also enabling precise single-point temperature control of the controlled equipment with high temperature requirements, satisfying its temperature requirements without affecting its performance or lifespan.

[0071] The application scenarios of the temperature control method provided in the embodiments of this application are described below. For example... Figure 2 As shown, the target space contains a main temperature control device, a controlled temperature device, a cold storage temperature control device, and other devices.

[0072] The main temperature control device is used to control the ambient temperature of the target space, thereby controlling the temperature of the equipment within the target space. For example, it can be used to control the temperature of the controlled equipment and other equipment within the target space.

[0073] The controlled temperature device is the equipment in the target space that has a higher temperature requirement, while other equipment is the equipment in the target space that has a lower temperature requirement. For example, if the temperature control requirement is cooling, the other equipment must have a temperature requirement of no higher than 35°C, while the controlled temperature device must have a temperature requirement of no higher than 25°C; or, if the temperature control requirement is heating, the other equipment must have a temperature requirement of no lower than 10°C, while the controlled temperature device must have a temperature requirement of no lower than 15°C, etc. There are no restrictions here.

[0074] It is worth noting that the 35℃, 25℃, 10℃ and 15℃ mentioned above are examples of temperature requirements for different equipment and do not constitute a limitation on the temperature requirements. The temperature-controlled equipment and other equipment can also have other temperature requirements, as long as the temperature required by the temperature-controlled equipment is lower than the temperature required by other equipment when the temperature control requirement is cooling, and the temperature required by the temperature-controlled equipment is higher than the temperature required by other equipment when the temperature control requirement is heating. No limitation is made here.

[0075] Cold storage temperature control equipment is used to store cold or heat during the process of the main temperature control equipment controlling the temperature with high power consumption, and to release cold or heat during the process of the main temperature control equipment controlling the temperature with low power consumption, thereby achieving precise temperature control of the controlled equipment and saving power consumption of the main temperature control equipment.

[0076] To ensure accurate temperature control of the controlled equipment by the cold storage temperature control equipment, the equipment should be placed close to the controlled equipment. For example, the cold storage temperature control equipment can be placed right next to the controlled equipment, or the controlled equipment can be placed inside the cabinet where the cold storage temperature control equipment is located; there are no restrictions here.

[0077] It is worth noting that, Figure 2 This is an example of an application scenario for the temperature control device provided in the embodiments of this application. It does not limit the number of temperature-controlled devices or other devices in the target space. There may be more temperature-controlled devices or more other devices in the target space, which is not limited here.

[0078] Optionally, if there are multiple temperature-controlled devices, the number of cold storage temperature control devices can be multiple or just one; there is no limitation here. If the number of cold storage temperature control devices is the same as the number of temperature-controlled devices, then the cold storage temperature control device is used to control the temperature of a single temperature-controlled device; if the number of cold storage temperature control devices is less than the number of temperature-controlled devices, then there may be a cold storage temperature control device used to control the temperature of multiple temperature-controlled devices; there is no limitation here.

[0079] In this embodiment of the application, temperature control can be achieved by controlling the main temperature control device and the cold storage temperature control device, such as... Figure 3 In the architecture shown, the control device can interact with the main temperature control device, the cold storage temperature control device, the controlled temperature device, and other devices in the target space to achieve temperature control of the controlled temperature device and other devices.

[0080] Optionally, the control device can also interact with the network management system to obtain temperature control-related information from the network management system.

[0081] In this embodiment, the target space can be a communication equipment room, and the temperature-controlled equipment and other equipment are communication devices, such as a building base band unit (BBU). Besides a communication equipment room, the target space can also be other spaces, such as a server room, etc., and is not limited here.

[0082] The application scenarios and architecture of the embodiments of this application have been described above. The temperature control method provided by the embodiments of this application will be described next. Please refer to... Figure 4 The temperature control method provided in this application includes:

[0083] 401. Cold storage and temperature control equipment for cold storage.

[0084] Cold storage temperature control equipment can store cold energy. When the cooling temperature of the main temperature control equipment is not higher than the first preset temperature, the cold storage temperature control equipment can store the cold energy of the main temperature control equipment.

[0085] The first preset temperature can be the upper limit temperature for cold storage of the cold storage temperature control device. The cold storage temperature control device can store cold in an environment where the temperature is not higher than the first preset temperature. For example, if the cold storage material of the cold storage temperature control device is a phase change cold storage material, then the first preset temperature can be the phase change point of the material, such as 20°C.

[0086] by Figure 5 For example, if the temperature required by the controlled device is 25℃ and the temperature required by other devices is 35℃, and the first preset temperature is 20℃, which is the phase change point of the phase change cold storage material in the cold storage temperature control device, then the cold storage temperature control device can start storing cold when the cooling temperature of the main temperature control device is lower than 20℃.

[0087] It is worth noting that, in addition to phase change cold storage materials, cold storage temperature control equipment can also include other types of cold storage materials, such as sensible heat cold storage materials, thermochemical cold storage materials, adsorption cold storage materials, etc., which are not limited here. The first preset temperature corresponds to the selection of the cold storage material, which is not limited here.

[0088] 402. Cold storage temperature control equipment releases cold to the temperature-controlled equipment.

[0089] The cold storage temperature control device stores cold energy in step 401, and can then release the stored cold energy to the controlled temperature device to cool it down. Specifically, the cold storage temperature control device can release cold energy to the controlled temperature device when the cooling temperature of the main temperature control device is not lower than the second preset temperature.

[0090] The second preset temperature can be the required temperature of the controlled device; that is, in a cooling scenario, the controlled device needs to maintain a temperature no higher than the second preset temperature; in a heating scenario, the controlled device needs to maintain a temperature no lower than the second preset temperature. Taking a cooling scenario as an example... Figure 5 For example, the second preset temperature is 25℃.

[0091] The second preset temperature is higher than the first preset temperature.

[0092] Cold storage temperature control equipment releases cold to the controlled equipment, which can lower the actual temperature of the controlled equipment by 25°C compared to the required temperature.

[0093] When the ambient temperature of the temperature-controlled equipment is higher than the required temperature, the cold storage temperature control equipment can precisely cool the temperature-controlled equipment, ensuring that the actual temperature of the temperature-controlled equipment meets the temperature requirements and avoiding damage to the performance or lifespan of the temperature-controlled equipment caused by the temperature not meeting the requirements.

[0094] In this embodiment, when cooling the controlled temperature device, the cold storage temperature control device stores cold energy when the main temperature control device's cooling temperature is low; when the main temperature control device's cooling temperature is high, the cold storage temperature control device releases the stored cold energy to the controlled temperature device. This allows the controlled temperature device to maintain a lower temperature when the main temperature control device's cooling temperature is high, thus meeting the device's required temperature. Through reasonable regulation of the cold energy, the main temperature control device can meet the temperature requirements of all devices in the target space at a higher cooling temperature, saving energy consumption.

[0095] Optionally, in this embodiment, the cold storage and temperature control device can store cold during off-peak electricity consumption periods and release cold to the controlled equipment during peak electricity consumption periods.

[0096] In this embodiment, by storing cold during off-peak hours and releasing it during peak hours, the main temperature control device can achieve higher cooling temperatures to control the temperature of equipment in the target space during peak hours. This saves power consumption of the main temperature control device during peak hours and reduces the power supply pressure during peak periods. Essentially, it uses electricity from off-peak hours to cool the controlled equipment during peak hours, balancing power consumption between peak and off-peak periods from the perspective of the overall power grid, achieving reasonable power consumption regulation. Furthermore, since the unit price of electricity is higher during peak hours, saving power consumption of the main temperature control device during peak hours also saves on temperature control costs.

[0097] It is worth noting that, Figure 4 The embodiments use a refrigeration scenario as an example to illustrate the temperature control operation of a cold storage temperature control device for single-point cooling of the controlled device. In a heating scenario, the process is similar, except that the cold storage temperature control device stores and releases heat, and the conditions that trigger the heat storage and release of the cold storage temperature control device are different, which will not be described in detail here.

[0098] Optionally, in this embodiment, the operating status of the cold storage temperature control device can be controlled by a control device. This, combined with information from devices outside the cold storage temperature control device, allows for precise control of the cold storage and release or heat storage and release of the cold storage temperature control device, achieving optimal energy-saving effects. This embodiment uses a refrigeration scenario as an example for illustration; please refer to [link to relevant documentation]. Figure 6 The method includes:

[0099] 601. The control equipment controls the cooling temperature of the main temperature control equipment to be no higher than the first preset temperature, and transmits the first signal to the cold storage temperature control equipment.

[0100] The control device can control the cooling temperature of the main temperature control device to not exceed the first preset temperature during off-peak electricity consumption periods, and transmit the first signal to the cold storage temperature control device. The first signal is used to instruct the cold storage temperature control device to store cold.

[0101] For details regarding the first preset temperature and the cold storage temperature control equipment, please refer to [link / reference]. Figure 4 Step 401 of the illustrated embodiment will not be repeated here.

[0102] by Figure 7 For example, taking a first preset temperature of 20℃ as an example, the control equipment can control the main temperature control equipment to cool the target space at a temperature of 15℃, thereby ensuring that all equipment in the target space is in an environment of 15℃. This satisfies the 25℃ requirement of the controlled equipment and the 35℃ requirement of other equipment.

[0103] Since the cooling temperature of the main temperature control device is 15°C, which is lower than the first preset temperature of 20°C, the cold storage temperature control device in the target space can store cold at this temperature. Therefore, the control device transmits the first signal to the cold storage temperature control device, instructing the cold storage temperature control device to store cold.

[0104] Optionally, the cold storage temperature control device can not only store cold according to the instructions of the control equipment, but also according to other conditions. For example, it can start storing cold when the ambient temperature is lower than a first preset temperature, based on the detected ambient temperature around the cold storage control device. This is not limited here.

[0105] 602. Cold storage and temperature control equipment for cold storage.

[0106] See step 602. Figure 4 Step 401 of the illustrated embodiment will not be repeated here.

[0107] 603. The control equipment controls the cooling temperature of the main temperature control device to be no lower than the second preset temperature, and transmits the second signal to the cold storage temperature control device.

[0108] During peak electricity consumption periods, the control device can control the cooling temperature of the main temperature control device to be no lower than the second preset temperature, and transmit a second signal to the cold storage temperature control device. The second signal is used to instruct the cold storage temperature control device to release cold to the controlled temperature device.

[0109] For details regarding the second preset temperature and the cold storage temperature control equipment, please refer to [link / reference]. Figure 4 Step 402 of the illustrated embodiment will not be repeated here.

[0110] by Figure 7 For example, taking a second preset temperature of 25℃ as an example, the control equipment can control the main temperature control equipment to cool the target space at a temperature of 35℃, thereby ensuring that all equipment in the target space is in a 35℃ environment. The 35℃ cooling temperature of the main temperature control equipment meets the 35℃ requirement of other equipment.

[0111] Since the cold storage temperature control device stores cold energy in step 602, when the ambient temperature around the controlled device does not meet the needs of the controlled device, the cold storage temperature control device can reduce the temperature of the controlled device by the cold energy stored in step 602 to meet the needs of the controlled device.

[0112] Specifically, the second signal sent by the main temperature control device to the cold storage temperature control device is used to instruct the cold storage temperature control device to release cold to the controlled temperature device in order to maintain the temperature of the controlled temperature device not higher than the second preset temperature of 25°C.

[0113] Optionally, the second signal may include information about a second preset temperature. The controlled temperature device controls the amount of cold energy released according to the second preset temperature contained in the second signal, so that the controlled temperature device meets the requirements of the second preset temperature, but does not release too much cold energy and cause the temperature of the controlled temperature device to be lower than the second preset temperature, resulting in cold energy release redundancy for the controlled temperature device and wasting the cold energy stored in the cold storage temperature control device.

[0114] Optionally, the cold storage temperature control device can release cold not only according to the instructions of the control device, but also according to other conditions. For example, it can start releasing cold when the ambient temperature around the cold storage control device is higher than a second preset temperature, etc., without limitation.

[0115] 604. Cold storage temperature control equipment releases cold to the temperature-controlled equipment.

[0116] See step 604. Figure 4 Step 402 of the illustrated embodiment will not be repeated here.

[0117] 605. Cold storage temperature control equipment cools down the controlled equipment.

[0118] Optionally, if the cooling temperature of the main temperature control device is higher than the second preset temperature, the cold storage temperature control device can cool down the controlled device after the cold energy stored in the cold storage temperature control device has been released.

[0119] In this embodiment, after the cold energy stored in the cold storage temperature control device is released, the cold storage temperature control device cools the controlled device through refrigeration, so that the main temperature control device does not need to lower its refrigeration temperature to meet the temperature requirements of the controlled device. The refrigeration of the cold storage temperature control device is only used to cool the controlled device, with a smaller cooling range and lower energy consumption; the refrigeration of the main temperature control device is used to lower the overall temperature of the target space environment, with a larger cooling range and higher energy consumption. Therefore, to meet the temperature requirements of the controlled device, the cold storage temperature control device uses refrigeration, which lowers the refrigeration temperature compared to the main temperature control device, thus saving energy.

[0120] It is worth noting that step 605 is an optional step. Step 605 is executed when the cooling temperature of the main temperature control device is higher than the second preset temperature and the cold energy stored in the cold storage temperature control device has been released. If the above conditions do not occur, step 605 may not be executed, and this is not a limitation.

[0121] In this embodiment, by storing cold during off-peak hours and releasing it during peak hours, the main temperature control device can achieve higher cooling temperatures to control the temperature of equipment in the target space during peak hours. This saves power consumption of the main temperature control device during peak hours and reduces the power supply pressure during peak periods. Essentially, it uses electricity from off-peak hours to cool the controlled equipment during peak hours, balancing power consumption between peak and off-peak periods from the perspective of the overall power grid, achieving reasonable power consumption regulation. Furthermore, since the unit price of electricity is higher during peak hours, saving power consumption of the main temperature control device during peak hours also saves on temperature control costs.

[0122] Optionally, in steps 601 and 603, the control device can schedule the main temperature control device and the cold storage temperature control device not only based on peak and off-peak electricity consumption periods, but also based on other information. For example, scheduling can be based on weather conditions, the workload of the controlled equipment, the actual temperature of the controlled equipment, etc., which are not limited here.

[0123] Taking weather as an example, the control device can obtain the weather information for the target space from the network management system. Based on the weather, it can adjust the duration of cooling at a temperature lower than the first preset temperature or the duration of cooling temperature in step 401 or step 602. For example, if the temperature in the area is high, the duration of cooling at a temperature lower than the first preset temperature in step 401 or step 602 can be appropriately extended, so that the cold storage temperature control device can store more cold energy to cope with the higher temperature.

[0124] Optionally, the main temperature control device and the cold storage temperature control device can be connected by a heat pipe to achieve heat exchange between them, thereby transferring cold or heat.

[0125] In this embodiment, a heat pipe connects the main temperature control device and the cold storage temperature control device. Compared to direct heat exchange through air, the heat pipe improves the energy transfer efficiency of heat exchange, thereby reducing energy waste. When the main temperature control device cools at a low temperature for the same duration, the cold storage capacity of the cold storage temperature control device can be increased, extending the cold release time of the cold storage temperature control device to the controlled device. Conversely, when the main temperature control device cools at the same low temperature, the cooling time of the main temperature control device can be reduced. This reduces energy consumption.

[0126] It is worth noting that, Figures 4 to 7 The embodiments shown all use a cooling scenario as an example to illustrate the temperature control method provided in this application. In a heating scenario, heat can also be stored through a cold storage temperature control device to achieve heat transfer over time. The specific process is the same as... Figures 4 to 7 The embodiments shown are similar and will not be described again here. In this method, the main temperature control device, which controls the temperature by lowering the ambient temperature in the target space during a refrigeration scenario, has its function and connection relationship replaced by a secondary temperature control device that controls the temperature by raising the ambient temperature in the target space.

[0127] It is worth noting that the main temperature control device and the auxiliary temperature control device can be the same device, such as an air conditioner that can both cool and heat; the main temperature control device and the auxiliary temperature control device can also be different devices, such as an air conditioner as the main temperature control device and a heater as the auxiliary temperature control device, etc., without limitation here.

[0128] In the embodiments of this application, Figure 4 The steps shown in step 402, and Figure 6 In step 604 shown, the cold storage temperature control equipment achieves single-point cooling of the controlled equipment by releasing cold. Since the cold storage temperature control equipment in this method achieves the transfer of cold energy over time through the storage and release of cold energy, and does not require the cold storage temperature control equipment to actively cool, this method is also called passive cooling.

[0129] Figure 6 In step 605 shown, the cold storage temperature control device achieves single-point cooling of the controlled temperature device through refrigeration. This requires the cold storage temperature control device to actively refrigerate, so this method is also called active refrigeration.

[0130] The following example, using a refrigeration scenario, illustrates the energy-saving and cost-saving effects of the temperature control method provided in this application embodiment on the temperature control efficiency.

[0131] Table 1 compares the energy savings before and after passive cooling. As shown in Table 1, before energy saving, the air conditioner maintains a constant temperature of 25°C, and the power consumption remains constant over time, while the electricity cost varies depending on the electricity price during that period. In the real-time precision cooling solution provided in this application, the cooling temperature of the air conditioner (main temperature control device) can change over time, and precise temperature control of the controlled equipment is ensured through a cold storage temperature control device.

[0132] For example, the time period corresponding to the electricity price of 1.2 yuan / KW in Table 1 is the peak electricity consumption period, and the other time periods are off-peak electricity consumption periods.

[0133] As shown in Table 1, 0:00-5:59 is the off-peak electricity consumption period, with an electricity price of 0.3 yuan / KW. During 0:00-0:59, the air conditioner cools at 35℃, generating 5.2KW / h of cooling capacity and consuming 2.08KW / h of electricity; the cold storage temperature control device releases 0.5KW / h of cooling capacity to the controlled equipment, achieving single-point temperature control. During 1:00-1:59, the air conditioner cools at x℃, and the cold storage temperature control device stores cold energy. The temperature variations from 2:00-3:59 and 4:00-5:59 are the same as those from 0:00-0:59 and 1:00-1:59, and will not be repeated here. Here, x does not exceed the upper limit temperature for cold storage of the cold storage temperature control device.

[0134] The period from 6:00 to 7:59 is also a non-peak electricity consumption period. Because the grid load during this period is higher than that from 1:00 to 1:59, the electricity price is 0.7 yuan / KW higher. Since the cold storage temperature control equipment completes its cold storage during the 1:00-1:59 and 4:00-5:59 periods, the air conditioner can cool at a temperature higher than or equal to 25℃ during the 6:00-7:59 period. The cold storage temperature control equipment uses the stored cold energy to control the temperature of the controlled equipment at a single point, maintaining the temperature of the controlled equipment no higher than 25℃.

[0135] The peak electricity consumption period is from 8:00 to 10:59. In order to reduce the load on the power grid and save electricity costs, the air conditioner is cooled at a temperature of 25°C. The cold storage temperature control equipment controls the temperature of the controlled equipment at a single point by storing cold energy.

[0136] The changes in air conditioning cooling temperature from 0:00 to 10:59, as well as the changes in cold storage and temperature control equipment, illustrate the situation during off-peak and peak electricity consumption periods. The situation after 10:59 in Table 1 is similar and will not be repeated here.

[0137] During the period from 14:00 to 14:59, the air conditioner provides cooling at a temperature of x+Δ, and the cold storage temperature control equipment stores the cold. Here, x+Δ does not exceed the upper limit temperature for cold storage of the cold storage temperature control equipment, and Δ is not less than 0.

[0138] It is worth noting that the changes in the cooling temperature of the air conditioner and the changes in the cold storage and release of the cold storage temperature control device during the non-peak electricity consumption period shown in Table 1 are only an example of the embodiments of this application and do not impose any limitation on the cooling temperature of the main temperature control device during the non-peak electricity consumption period. The main temperature control device can also adjust the cooling temperature according to other rules, as long as the cold storage temperature control device stores cold during the non-peak electricity consumption period, which is not limited here.

[0139] Table 1

[0140]

[0141] As shown in Table 1, compared to cooling at a constant 25°C, by scheduling the air conditioner and cold storage temperature control equipment according to the rules in Table 1, 13.1% of electricity consumption and 18.1% of electricity costs can be saved, resulting in a daily electricity cost saving of 9.7 yuan and an annual electricity cost saving of 3541.5 yuan, thus reducing the cost of temperature control.

[0142] Table 2 compares the energy savings before and after the active cooling mode. As shown in Table 2, before energy saving, the air conditioner cools at a constant 25℃, producing 8 kW / h of cooling capacity and consuming 3.2 kW / h of electricity. The cooling capacity and electricity consumption remain constant over time, while the electricity cost varies depending on the electricity price during that period. In the active mode precision cooling solution, the air conditioner (main temperature control unit) cools at 35℃, producing 5.2 kW / h of cooling capacity. The cold storage temperature control device actively cools, producing 0.5 kW / h of cooling capacity per hour. This generated cooling capacity is released to the controlled equipment, achieving single-point temperature control.

[0143] Since the cold storage temperature control device is located within the target space, its cooling action will generate an equivalent amount of heat within that space. This heat requires the original air conditioner to generate additional cooling capacity to balance the temperature and maintain the target space at 35°C. For details regarding this power consumption, please refer to the original air conditioner's add-ons.

[0144] Table 2

[0145]

[0146] As shown in Table 2, compared to cooling at a constant 25°C, controlling the temperature according to the rules in Table 2 can save 20.0% of electricity and electricity costs, saving 10.7 yuan per day and 3923.1 yuan per year, thus reducing the cost of temperature control.
