Description

Technical Field

[0001] This invention relates to the field of water heater heat exchange control technology, and in particular to a water supply control method and device for heat exchange water. Background Technology

[0002] Water heaters, as devices that can heat cold water to a certain temperature, have become an essential appliance in most households, greatly improving the convenience and comfort of people's daily lives.

[0003] Currently, water heaters typically heat water first, then exchange heat with phase change material (PCM) in the heater's insulation tank. This allows the PCM to store heat energy, which is then used to heat the user's hot water. However, practical experience has shown that the current method of heat exchange between the water and PCM doesn't consider the user's hot water demand. Instead, the water is continuously controlled to flow through the pipes until the switch is turned off, achieving heat exchange with the PCM. This results in heat loss and energy waste when the user's hot water demand is low, hindering the water heater's energy efficiency. Therefore, providing a method to improve the reliability and accuracy of water flow control for heat exchange is crucial. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or end that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or ends.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0087] This invention discloses a water transport control method and device for heat exchange water, which can improve the reliability and accuracy of water transport control for heat exchange water, thereby reducing unnecessary heat loss and power consumption when heat exchange water exchanges heat with phase change materials, thus facilitating energy-saving control of water heaters.

[0088] Example 1

[0089] Please see Figure 2 , Figure 2 This is a schematic flowchart of a water supply control method for heat exchange water disclosed in an embodiment of the present invention. Figure 2The described water transport control method for heat exchange water can be applied to control the water transport of heat exchange water in various types of water heaters, such as solar water heaters and electric water heaters, etc., and this invention is not limited to these types. Optionally, this method can be implemented by a water transport control device, which can be integrated into the water heater equipment. When the water transport control device exists independently, it can also be a local server or cloud server, etc., used to process the water transport control process of heat exchange water, and this invention is not limited to these types. Figure 2 As shown, the water supply control method for heat exchange water may include the following operations:

[0090] 101. Obtain the user's water output demand parameters, the pipe parameters of the heat exchange pipes in the water heater, and the target parameters of the water used for heat exchange.

[0091] In this embodiment of the invention, the heat exchange pipe is covered with a phase change material. Optionally, the outlet water demand parameters include hot water temperature demand parameters and hot water volume demand parameters, and may also include hot water usage time demand parameters, etc.; while the target parameters of the heat exchange water include the temperature parameters and water volume parameters of the heat exchange water, and may also include the heat capacity parameters, density parameters, and type parameters of the heat exchange water, etc.

[0092] 102. Determine the water supply control parameters for heat exchange based on the water demand parameters, the pipe parameters of the heat exchange pipeline, and the target parameters of the heat exchange water.

[0093] In this embodiment of the invention, the optional water transport control parameters include at least one of water transport volume control parameters, water transport rate control parameters, and water transport cycle number parameters, and may also include water transport duration control parameters, water transport direction control parameters, etc.

[0094] 103. Based on the water transport control parameters of the heat exchange water, the water transport of the heat exchange water is controlled so that the heat exchange water flows inside the heat exchange pipe to exchange heat with the phase change material outside the heat exchange pipe.

[0095] In embodiments of the present invention, for example, such as Figure 1 As shown, after the heating module heats the heat exchange water, the water flow control device can control the water flow slowly or quickly inside the heat exchange pipe according to the water flow control parameters. This allows the phase change material outside the heat exchange pipe to absorb and store the heat from the water. After one round of heat exchange, if the water still retains some heat, it can undergo several more rounds of heat exchange based on the user's hot water demand. This ensures that the heat stored in the phase change material meets the user's hot water needs, and the heat exchanged water is then stored in a container. Figure 1 In the water tank shown on the right.

[0096] It is evident that implementing the embodiments of the present invention enables intelligent water transport control of heat exchange water based on the user's water output requirements, such as water volume and water transport rate control. This improves the reliability and accuracy of water transport control for heat exchange water, thereby reducing unnecessary heat loss and energy consumption during heat exchange between the heat exchange water and the phase change material, which is beneficial for achieving energy-saving control of the water heater.

[0097] Example 2

[0098] Please see Figure 3 , Figure 3 This is a schematic flowchart of another water supply control method for heat exchange water disclosed in an embodiment of the present invention. Figure 3 The described water transport control method for heat exchange water can be applied to control the water transport of heat exchange water in various types of water heaters, such as solar water heaters and electric water heaters, etc., and this invention is not limited to these types. Optionally, this method can be implemented by a water transport control device, which can be integrated into the water heater equipment. When the water transport control device exists independently, it can also be a local server or cloud server, etc., used to process the water transport control process of heat exchange water, and this invention is not limited to these types. Figure 3 As shown, the water supply control method for heat exchange water may include the following operations:

[0099] 201. Obtain the user's water output demand parameters, the pipe parameters of the heat exchange pipes in the water heater, and the target parameters of the water used for heat exchange.

[0100] In this embodiment of the invention, optionally, the pipe parameters include pipe diameter parameters and pipe material parameters, and may also include pipe length parameters, pipe curvature parameters, etc.

[0101] 202. Based on the hot water temperature requirement parameters and hot water volume requirement parameters, calculate the total heat exchange requirement parameters of the phase change material.

[0102] In this embodiment of the invention, the user's total heat demand parameter for hot water is determined based on the hot water temperature demand parameter and the hot water volume demand parameter. Then, based on the user's total heat demand parameter for hot water, the total heat demand parameter for heat exchange of the phase change material is predicted to determine whether the current heat exchange water meets the heat exchange demand conditions.

[0103] 203. Calculate the current total heat parameters of the heat exchange water based on the temperature and flow parameters of the heat exchange water.

[0104] In this embodiment of the invention, the undetermined total heat parameters of the heat exchange water can be calculated based on the formula Q = c * m * Δt, where Q is the undetermined total heat parameter of the heat exchange water, c is the heat capacity parameter of the heat exchange water, m is the water volume parameter of the heat exchange water, and Δt is the predicted temperature parameter of the heat exchange water before and after heat exchange. Then, combined with the predicted heat loss of the heat exchange water during heat exchange with the phase change material, the current total heat parameters of the heat exchange water can be calculated.

[0105] 204. Based on the total heat demand parameter and the current total heat parameter, determine whether the current total heat parameter is greater than the total heat demand parameter.

[0106] In this embodiment of the invention, when the judgment result of step 204 is yes, step 205 is triggered; when the judgment result of step 204 is no, step 206 is triggered.

[0107] 205. Based on the water demand parameters, the pipeline parameters of the heat exchange pipeline, and the target parameters of the heat exchange water, determine the water transport control parameters for the heat exchange water.

[0108] 206. Perform a heating operation on the heat exchange water to obtain heated heat exchange water. Update the current total heat parameters of the heat exchange water based on the temperature and water volume parameters of the heated heat exchange water, and trigger the operation in step 204 to determine whether the current total heat parameters are greater than the total heat demand parameters based on the total heat demand parameters and the current total heat parameters.

[0109] In this embodiment of the invention, the heat exchange water needs to be heated first so that it can meet the heat exchange requirements between itself and the phase change material. For example, if the current total heat parameter of the heat exchange water is greater than the total heat exchange requirement parameter, the water transport control parameters of the heat exchange water are then determined based on the target parameters of the heat exchange water that have met the heat exchange requirements.

[0110] 207. Based on the water flow control parameters of the heat exchange water, control the flow of the heat exchange water so that the heat exchange water flows inside the heat exchange pipe to exchange heat with the phase change material outside the heat exchange pipe.

[0111] In this embodiment of the invention, for other descriptions of steps 201, 205 and 207, please refer to the detailed description of steps 101-103 in Embodiment 1. This embodiment of the invention will not repeat them.

[0112] As can be seen, implementing the embodiments of the present invention can determine whether the current total heat parameters of the heat exchange water meet the heat exchange requirements between the heat exchange water and the phase change material based on the user's water output demand parameters and the target parameters of the heat exchange water. If yes, the water transport control parameters of the heat exchange water are determined; if not, the heating operation of the heat exchange water continues until the heat exchange requirements are met. This is beneficial to improving the reliability and accuracy of the heating control of the heat exchange water, which in turn is beneficial to improving the reliability and accuracy of the determination of the water transport control parameters of the heat exchange water, thereby improving the accuracy of the water transport control of the heat exchange water. While meeting the user's water output requirements, it can also minimize unnecessary heat loss and power consumption.

[0113] In an optional embodiment, step 205 above, determining the water supply control parameters for heat exchange based on the effluent demand parameters, the pipe parameters of the heat exchange pipeline, and the target parameters of the heat exchange water, includes:

[0114] The heat transfer coefficient of the heat exchange water is calculated based on the heat capacity parameters, density parameters, pipe diameter parameters, and pipe material parameters of the heat exchange water.

[0115] Predict the inlet and outlet temperature difference parameters of the heat exchange water, and determine the heat transfer area parameters of the heat exchange water based on the heat transfer coefficient of the heat exchange water, the inlet and outlet temperature difference parameters, and the total heat demand parameters of the phase change material.

[0116] Based on the heat transfer area parameters of the heat exchange water, determine the water supply control parameters for the heat exchange water.

[0117] In this optional embodiment, for example, in the process of determining the water transport control parameters of the heat exchange water, the heat transfer coefficient and heat transfer area parameters of the heat exchange water can be simulated and calculated based on the heat capacity parameters, density parameters, and pipe parameters of the heat exchange pipe, combined with various flow rate control conditions of the heat exchange water. Then, the optimal solution with sufficient heat transfer and minimal heat loss—that is, the optimal flow rate control parameters—can be found, thereby determining the water transport control parameters of the heat exchange water.

[0118] As can be seen, this optional embodiment can calculate the heat transfer coefficient of the heat exchange water based on the heat capacity parameters, density parameters, and pipe parameters of the heat exchange water. Then, it determines the heat transfer area parameters of the heat exchange water based on the inlet and outlet temperature difference parameters of the heat exchange water and the total heat demand parameters of the phase change material. This realizes the process of determining the water transport control parameters of the heat exchange water. In this way, the reliability and accuracy of determining the water transport control parameters of the heat exchange water can be improved, thereby improving the reliability and accuracy of the water transport control of the heat exchange water. This ensures sufficient heat exchange between the heat exchange water and the phase change material and reduces heat loss.

[0119] In another optional embodiment, the step of determining the water supply control parameters for the heat exchange water based on the heat transfer area parameters of the heat exchange water includes:

[0120] Obtain the material parameters of the phase change material;

[0121] Determine the heat transfer between the phase change material and the heat exchange pipe based on the material parameters and pipe parameters;

[0122] Based on the heat transfer conditions and the heat transfer area parameters of the heat exchange water, determine the water supply control parameters for the heat exchange water.

[0123] In this optional embodiment, such as Figure 1 As shown, the heat exchange process between the heat exchange water and the phase change material (PCM) is achieved through heat exchange pipes. The characteristics of the pipes, the PCM's coverage of the pipes, and the PCM's own material properties all affect the heat absorption process of the PCM, which in turn affects the heat transfer process of the heat exchange water. Therefore, it is necessary to determine the heat transfer between the PCM and the heat exchange pipes. Optionally, the material parameters include at least one of the following: material type parameters, material heat absorption parameters, and material coverage of the pipes.

[0124] As can be seen, this optional embodiment can determine the heat transfer between the phase change material and the heat exchange pipe based on the material parameters of the phase change material and the pipe parameters of the heat exchange pipe. Then, based on the heat transfer condition and the heat transfer area parameters of the heat exchange water, the water supply control parameters of the heat exchange water can be determined. This can improve the comprehensiveness of the analysis of the heat exchange between the heat exchange water and the phase change material, and further improve the reliability and accuracy of the water supply control of the heat exchange water, thereby facilitating the full heat exchange between the heat exchange water and the phase change material.

[0125] In another optional embodiment, the step of determining the water supply control parameters for the heat exchange water based on the heat transfer conditions and the heat transfer area parameters of the heat exchange water includes:

[0126] Obtain the casing parameters of the water heater's insulation box;

[0127] Based on the box parameters and material parameters of the insulation box, the heat dissipation of the phase change material is predicted, and the water supply control parameters of the heat exchange water are determined based on the heat dissipation, heat transfer and heat transfer area parameters of the heat exchange water.

[0128] In this optional embodiment, wherein, as Figure 1As shown, the insulation box contains heat exchange pipes and phase change material. Therefore, during the heat exchange process between the heat exchange water and the phase change material, heat transfer also occurs between the phase change material and the insulation box, which may cause heat loss during the heat exchange process. Therefore, it is necessary to further predict the heat dissipation of the phase change material due to the aforementioned heat transfer. Optionally, the box parameters include at least one of the following: box material parameters, box surface area parameters, and the contact condition between the insulation box and the phase change material.

[0129] Furthermore, as an optional implementation, based on the box parameters and material parameters of the insulation box, the heat dissipation of the phase change material is predicted, including:

[0130] Obtain environmental parameters of the external environment where the insulation box is located;

[0131] Based on the environmental parameters of the external environment and the parameters of the insulation box, predict the heat dissipation of the insulation box;

[0132] Based on the heat dissipation of the enclosure and the material parameters, predict the heat dissipation of the phase change material.

[0133] In this optional embodiment, the heat dissipation of the phase change material is predicted by further considering the heat loss between the external environment and the insulation enclosure. Optionally, the environmental parameters include ambient temperature and / or ambient humidity.

[0134] As can be seen, this optional embodiment can further predict the heat dissipation of the phase change material based on the box parameters of the insulation box and the material parameters of the phase change material, combined with the environmental parameters of the external environment of the insulation box. Then, based on the heat dissipation, the heat transfer between the phase change material and the heat exchange pipe, and the heat transfer area parameters of the heat exchange water, the water supply control parameters for heat exchange water are determined. In this way, the heat loss caused by the insulation box and its external environment is fully analyzed, which can reduce the degree of heat exchange impact caused by the insulation box and the external environment, thereby helping to comprehensively improve the accuracy and effectiveness of determining the water supply control parameters for heat exchange water.

[0135] In yet another optional embodiment, before calculating the heat transfer coefficient of the heat exchange water based on the heat capacity parameter, density parameter, pipe diameter parameter, and pipe material parameter of the heat exchange water, the method further includes:

[0136] Obtain the water pump parameters used to control the water flow of the water heater;

[0137] Based on the pump parameters and pipe diameter parameters, predict the cross-sectional area ratio of heat exchange water in the heat exchange pipe when the pump is controlling water flow, and determine the impact of heat transfer on the heat exchange water based on the cross-sectional area ratio parameters.

[0138] Based on the extent to which heat transfer is affected, determine whether the degree of heat transfer impact corresponding to the affected situation is greater than or equal to the preset impact level;

[0139] When the judgment result is yes, the heat transfer coefficient of the heat exchange water is calculated based on the cross-sectional area ratio parameter, the heat capacity parameter, density parameter of the heat exchange water, the pipe diameter parameter of the heat exchange pipe, and the pipe material parameter.

[0140] When the judgment result is negative, the operation of calculating the heat transfer coefficient of the heat exchange water based on the heat capacity parameter, density parameter, pipe diameter parameter, and pipe material parameter of the heat exchange water is triggered.

[0141] In this optional embodiment, since the water pump parameters of the water heater may affect the sufficient flow of heat exchange water in the heat exchange pipes (i.e., the heat exchange water may not be able to fully contact the heat exchange pipes), thereby affecting the heat transfer between the heat exchange water and the phase change material, it is necessary to determine whether the heat transfer of the heat exchange water is affected. Optionally, the water pump parameters include outlet water pressure control parameters and / or outlet cross-sectional area parameters.

[0142] As can be seen, this optional embodiment can predict the cross-sectional proportion of heat exchange water in the heat exchange pipe during water pump operation control based on the pump parameters and the pipe diameter parameters of the heat exchange pipe. It can then determine the degree of impact on the heat transfer of the heat exchange water and calculate the heat transfer coefficient of the heat exchange water. This can further improve the reliability and accuracy of the calculation of the heat transfer coefficient of the heat exchange water, thereby improving the reliability and accuracy of the determination of the heat transfer area of ​​the heat exchange water. As a result, the accuracy of determining the water operation control parameters of the heat exchange water can be comprehensively improved.

If yes, it then performs the operation of determining the water transport control parameters for the heat exchange water; if not, it continues to heat the heat exchange water until the heat exchange requirements are met. This improves the reliability and accuracy of the heating control of the heat exchange water, which in turn improves the reliability and accuracy of determining the water transport control parameters for the heat exchange water, thereby improving the precision of the water transport control for the heat exchange water. While meeting the user's water output requirements, it can also minimize unnecessary heat loss and power consumption.
