It can be hot water or other fluids with a higher temperature, and the embodiments of the present application do not limit this. Among them, the temperature of the second temperature fluid is higher than that of the above first temperature fluid.

[0049] The above second temperature fluid delivery module 124 is a module for delivering the second temperature fluid to the container module 126. It can be a pipeline, and the embodiments of the present application do not limit the material and length of the pipeline, etc.

[0050] The above-mentioned first flow control module 125 is used to control the flow rates of the first-temperature fluid and the second-temperature fluid flowing into the container module 126.

In the embodiments of the present application, the first-temperature fluid and the second-temperature fluid are mixed and then flow into the container module 126, so that the container module 126 holds the fluid at the target temperature, that is, the temperature inside the container module 126 is controlled to reach the target temperature. Among them, the above-mentioned container module 126 can be an aquarium for daily household use, or a water dispenser or a washing machine that can provide daily water, etc. The embodiments of the present application do not limit this.

[0052] In one embodiment, the first end P1 of the above-mentioned first-temperature fluid delivery module 122 can be connected to the first-temperature fluid supply module 121, and the second end P2 of the first-temperature fluid delivery module 122 can be connected to the first input end I1 of the first flow control module 125.

The output end O of the first flow control module 125 can be connected to the above-mentioned container module 126.

[0053] Optionally, in order to facilitate determining the temperature of the first-temperature fluid output by the first-temperature fluid delivery module 122, a first temperature measurement module 127 is provided at the second end P2 of the first-temperature fluid delivery module 122. The above-mentioned first temperature measurement module 127 is used to measure the fluid temperature of the first-temperature fluid output by the first-temperature fluid delivery module 122.

[0054] Optionally, in order to facilitate determining the temperature of the second-temperature fluid output by the second-temperature fluid delivery module 124, a second temperature measurement module 128 is provided at the second end P2 of the second-temperature fluid delivery module 124. The above-mentioned second temperature measurement module 128 can be used to measure the fluid temperature of the second-temperature fluid output by the second-temperature fluid delivery module 124.

[0055] In the embodiments of the present application, based on the connection modes of the above refrigerant subsystem 11 and the connection modes of the fluid temperature control subsystem 12, by setting the positional relationship between the refrigerant subsystem 11 and the fluid temperature control subsystem 12 (for example Figure 1 in Figure 1 , the heat absorption module 2 is adjacent to or connected to the first temperature transfer module 122, and the condensation module is adjacent to or connected to the second temperature transfer module 124), it is possible to control the heat absorption module 112 to absorb the heat in the first temperature fluid transfer module to lower the temperature of the first temperature fluid, and control at least one condensation module to heat the second temperature fluid transfer module to increase the temperature of the second temperature fluid.

[0056] As an optional implementation manner, the condensation module set 111 may include two-stage condensation modules, and the second-stage condensation module may be used to heat the second temperature fluid transfer module.

[0057] As another optional implementation manner, the condensation module set 111 may include more than two-stage condensation modules, and at least two-stage condensation modules may be used to heat the second temperature fluid transfer module.

[0058] The fluid temperature control system provided by the embodiment of the present application includes a refrigerant subsystem and a fluid temperature control subsystem. The refrigerant subsystem includes a condensation module set and a heat absorption module. Among them, the condensation module set includes at least two serially connected condensation modules. The fluid temperature control subsystem includes a first temperature fluid supply module, a first temperature fluid delivery module, a second temperature fluid supply module, a second temperature fluid delivery module, a first flow control module, and a container module. Among them, the first end of the first temperature fluid delivery module is connected to the first temperature fluid supply module, the second end of the first temperature fluid delivery module is connected to the first input end of the first flow control module, the first end of the second temperature fluid delivery module is connected to the second temperature fluid supply module, the second end of the second temperature fluid delivery module is connected to the second input end of the first flow control module, and the output end of the first flow control module is connected to the container module. A first temperature measurement module is provided at the second end of the first temperature fluid delivery module, and a second temperature measurement module is provided at the second end of the second temperature fluid delivery module. The first temperature fluid supply module provides a first temperature fluid, the second temperature fluid supply module provides a second temperature fluid, and the temperature of the second temperature fluid is higher than that of the first temperature fluid. The heat absorption module is used to absorb the heat in the first temperature fluid delivery module. At least one condensation module is used to heat the second temperature fluid delivery module. With this system structure, by combining the fluid temperature control subsystem that needs to control the fluid temperature with the refrigerant subsystem, the waste heat released by the added condensation module in the refrigerant subsystem can be used to heat the second temperature fluid in the fluid temperature control subsystem, and the heat absorption function of the heat absorption module in the refrigerant subsystem can be used to absorb the heat of the first temperature fluid in the fluid temperature control subsystem. Therefore, the temperatures of the first temperature fluid and the second temperature fluid flowing into the container module can be controlled separately, so as to control the fluid temperature in the container module, achieving efficient and accurate control of the fluid temperature in the fluid temperature control subsystem by recovering the heat in the refrigerant subsystem, and thus achieving more energy-saving, safe and accurate control of the fluid temperature in the container.

[0059] See Figure 2 , which is a schematic structural diagram of another fluid temperature control system provided by the embodiment of the present application. As an embodiment, Figure 2 The system structure shown in Figure 1 On the basis of the system structure shown in Figure 2 The structure of the fluid temperature control system is further described. As shown in

[0060] As an implementation manner, Figure 1The shown container module 126 may include a first target container 21 and a buffer container 22. The above-mentioned first target container 21 may be a container for controlling the fluid temperature in this application, which may be an aquarium, a water dispenser, a washing machine, etc., and the embodiments of this application do not limit this. The above-mentioned buffer container 22 is used to fully exchange heat between the first temperature fluid and the second temperature fluid, so that the temperature of the fluid finally flowing out of the buffer container 22 is relatively stable.

[0061] Among them, the input end I of the buffer container 22 is connected to the output end O of the first flow control module 125, and the output end O of the buffer container 22 may be connected to the input end I of the first target container 21.

[0062] As an optional implementation manner, in order to enable the first temperature fluid and the second temperature fluid to be evenly mixed in the buffer container 22 and avoid stratification, the input end of the buffer container 22 may be a spiral or a layered water inlet module.

[0063] As an optional implementation manner, in order to ensure that the speed of the fluid in the buffer container 22 flowing into the first target container 21 is within a preset range, the output end of the buffer container 22 may be a porous water outlet plate or uniformly distributed water outlet holes.

[0064] As an implementation manner, the above-mentioned first temperature fluid supply module 121 may include a second flow control module 23, a first supply unit 24, and a second supply unit 25. The above-mentioned second flow control module 23 can be used to control the flow rate of the fluid provided by the first supply unit 24 and the second supply unit 25 for the first temperature fluid delivery module 122. The above-mentioned first supply unit 24 and the second supply unit 25 can be respectively used to provide first temperature fluids at different temperatures. In order to prevent the fluid from freezing in the first temperature fluid delivery module 122, the temperature of the fluid provided by the first supply unit 24 may be greater than the temperature of the fluid provided by the second supply unit 25.

[0065] Among them, the above-mentioned first supply unit 24 may be connected to the first input end I1 of the second flow control module 23, the second supply unit 25 may be connected to the second input end I2 of the second flow control module 23, and the output end O of the second flow control module 23 may be connected to the first end P1 of the first temperature fluid delivery module.

[0066] Based on the structure of the above-mentioned first temperature fluid supply module 121, Figure 2The fluid temperature control system shown may further include a second target container 26 and a second temperature fluid recovery module 27. Among them, the third temperature fluid in the second target container 26 is heated by at least one condensation module, and the second temperature fluid recovery module 27 is used to recover the third temperature fluid in the second target container 26 and heat the first supply unit 24, so that the temperature of the first temperature fluid in the first supply unit 24 is higher than the temperature of the first temperature fluid in the second supply unit 25, and the temperature of the third temperature fluid is higher than the temperature of the first temperature fluid.

[0067] As an implementation manner, the refrigerant subsystem 11 may further include a compression module 28 and a throttling module 29. Among them, the compression module 28 can be used to provide power for the refrigerant subsystem 11, so that the refrigerant in the refrigerant subsystem 11 can circulate in the system. It can be a compressor, and the application embodiment does not limit the model and size of the compressor. The throttling module 29 is used to convert the refrigerant from a high-pressure state to a low-pressure state.

[0068] Based on Figure 2 the connection method shown, in actual application, when the refrigerant subsystem 11 operates normally, it can include two states: low-power standby and rated-power heating:

[0069] The low-power standby is mainly to maintain the fluid temperature in the second target container 26 to ensure the fluid that can generate heat at any time. At this time, the power of the compression module 28 is relatively low, and the heat absorbed by the heat absorption module 112 is close to the heat released by the condensation module set 111. At this time, there is no risk of ice formation in the first temperature transfer module 122. Therefore, the first temperature fluid can be provided to the first temperature fluid transfer module 122 through the second supply unit 25.

[0070] The rated-power heating is mainly because the hot fluid in the second target container 26 is used, and the temperature of the second target container 26 is reduced, resulting in the need for the compression module 28 to increase power to produce hot fluid. Therefore, the heat throughput of the system increases significantly, which causes the temperature of the condensation module set 111 to drop sharply below zero, and the first temperature fluid transfer module 112 is prone to ice formation. Therefore, the first supply unit 24 and the second supply unit 25 need to provide the first temperature fluid to the first temperature fluid transfer module 112 at the same time. Among them, the second temperature fluid recovery module 27 can recover the third temperature fluid in the second target container 26 and heat the first supply unit 24, so as to ensure that the temperature of the first temperature fluid provided by the first supply unit 24 is higher than the temperature of the first temperature fluid provided by the second supply unit 25, so that the temperature of the first temperature fluid obtained after mixing the first supply unit 24 and the second supply unit 25 is higher than the freezing temperature, preventing the first temperature transfer module 122 from icing.

[0071] The fluid temperature control system provided by the embodiment of the present application sets two supply units in the first temperature fluid supply module, and uses the third temperature fluid in the recycled second target container to heat the fluid of one of the supply units, so as to mix the first temperature fluid provided by the two supply units, which can prevent the risk of icing in the first temperature fluid delivery module. Further, by setting a buffer container in the container module, it can ensure that the first temperature fluid and the second temperature fluid are fully mixed and flow into the first target container at a relatively stable flow rate, so as to more accurately control the fluid temperature in the first target container.

[0072] See Figure 3 , which is a flowchart of an embodiment of a fluid temperature control method provided by the embodiment of the present application. As an embodiment, Figure 3 The process shown can be applied to Figure 1 or Figure 2 The fluid temperature control system shown. As shown in Figure 3 , the process may include the following steps:

[0073] Step 301, obtain the target temperature set for the container module.

[0074] The above target temperature refers to the temperature value that needs to be reached and maintained for the fluid in the container module.

[0075] The above container module refers to a container for holding fluid and whose fluid temperature needs to be controlled, such as Figure 1 The container module 126 shown.

[0076] In the embodiment of the present application, before controlling the fluid temperature in the container module, the execution subject of the embodiment of the present application may first obtain the target temperature set for the above container module.

[0077] As an optional implementation manner, the container module may be connected to a display module. Based on this, the user can set the target temperature of the container module through the display module. When the execution subject of the embodiment of the present application detects the temperature value set by the user through the display module, it obtains the temperature value and determines the temperature value as the target temperature of the container module.

[0078] As another optional implementation manner, the execution subject of the embodiment of the present application may have a voice recognition module. Based on this, the user can set the target temperature of the container module by voice. After the execution subject of the embodiment of the present application detects the voice signal sent by the user, it can recognize the voice signal and determine the target temperature of the container module.

[0079] Step 302: Determine respectively the first fluid temperature of the first temperature fluid flowing into the container module by the first temperature fluid delivery module, the second fluid temperature of the second temperature fluid flowing into the container module by the second temperature fluid delivery module, and the current temperature of the fluid in the container module.

[0080] The above-mentioned first temperature fluid delivery module refers to the module in the fluid temperature control system for delivering the first temperature fluid to the container module. The above-mentioned first temperature fluid delivery module can be Figure 1 the first temperature fluid delivery module 122 of the system shown.

[0084] The above-mentioned second fluid temperature refers to the temperature of the second temperature fluid in the second temperature fluid delivery module when it flows into the container module.

[0085] The above-mentioned current temperature refers to the current temperature value of the fluid stored in the container module.

[0086] In the embodiment of the present application, after the execution subject of the embodiment of the present application obtains the target temperature set for the container module, since the temperature in the container module is adjusted by flowing the first temperature fluid and the second temperature fluid into the container module, therefore, the first fluid temperature of the first temperature fluid flowing into the container module by the first temperature fluid delivery module, the second fluid temperature of the second temperature fluid flowing into the container module by the second temperature fluid delivery module, and the current temperature of the fluid in the container module can be determined respectively first.

[0087] As an optional implementation manner, by Figure 1As can be seen from the system architecture shown, a first temperature measurement module 127 is provided at the second end P2 of the first temperature fluid delivery module 122, and a second temperature measurement module 128 is provided at the second end P2 of the second temperature fluid delivery module 124. Based on this, the execution subject of the embodiment of the present application can obtain the first fluid temperature of the first temperature fluid output by the first temperature fluid delivery module 122 through the above-mentioned first temperature measurement module 127, and obtain the second fluid temperature of the second temperature fluid output by the second temperature fluid delivery module 124 through the above-mentioned second temperature measurement module 128.

[0088] As an optional implementation manner, a container temperature measurement module (such as a temperature sensing bulb) can be preset in the container module. Based on this, the execution subject of the embodiment of the present application can obtain the current temperature of the fluid in the container module through this container temperature measurement module.

[0089] As another optional implementation manner, the user can input the current temperature of the fluid in the container module through the visualization interface. Based on this, the execution subject of the embodiment of the present application can obtain the current temperature of the fluid in the container module input by the user through the visualization interface.

[0090] As an optional implementation manner, the above-mentioned container module may include a first target container and a buffer container (such as Figure 1 the first target container 21 and the buffer container 22 shown). Based on this, the execution subject of the embodiment of the present application can obtain the current temperature of the fluid in the above-mentioned first target container, and determine the current temperature of the fluid in the container module as the current temperature of the fluid in the first target container.

[0091] Step 303: Determine the opening ratio between the first input end and the second input end of the first flow control module according to the above-mentioned target temperature, the above-mentioned first fluid temperature, the above-mentioned second fluid temperature, and the current temperature.

[0092] Step 304: Control the opening of the first input end and the second input end in the above-mentioned first flow control module according to the above-mentioned opening ratio, so that the current temperature of the fluid in the container module reaches the above-mentioned target temperature.

[0093] The following is a unified description of steps 303 and 304:

[0094] The above-mentioned first flow control module is used to control the flow rates of the first temperature fluid and the second temperature fluid flowing into the container module. It can be a three-way valve, and controls the flow rate of the first temperature fluid flowing into the container module by controlling the valve opening of the valve connecting the first input end of the first temperature fluid delivery module, and controls the flow rate of the second temperature fluid flowing into the container module by controlling the valve opening of the valve connecting the second input end of the second temperature fluid delivery module.

[0095] The above-mentioned opening ratio refers to the ratio between the valve opening of the first input end and the valve opening of the second input end in the first flow control module.

[0096] In the embodiments of the present application, in order to make the temperature of the fluid in the container module reach the above-mentioned target temperature, the execution entity of the embodiments of the present application can determine the opening ratio between the first input end and the second input end of the first flow control module according to the above-mentioned target temperature, the first fluid temperature, the second fluid temperature, and the current temperature.

[0097] As an optional implementation manner, it can be first determined whether the above-mentioned current temperature reaches the above-mentioned target temperature, and when it is determined that the current temperature does not reach the above-mentioned target temperature, the opening ratio between the first input end and the second input end of the first flow control module can be determined according to the above-mentioned target temperature, the first fluid temperature, the second fluid temperature, and the current temperature.

[0098] As an optional implementation manner, the first fluid temperature difference between the first fluid temperature and the target temperature, the second fluid temperature difference between the second fluid temperature and the target temperature, and the target temperature difference between the current temperature and the target temperature can be determined respectively. Then, the sum of the target temperature difference and the second fluid temperature difference can be determined to obtain the total temperature difference. Finally, the ratio between the above-mentioned total temperature difference and the first fluid temperature difference can be determined as the opening ratio between the first input end and the second input end of the first flow control module.

[0099] Among them, according to the specific heat capacity formula shown in the following formula (1), it can be known that the heat absorbed and released when the temperature of one volume of the first temperature fluid (such as cold water) and the second temperature fluid (such as hot water) both reach the target temperature is "c * the first fluid temperature difference" and "c * the second fluid temperature difference". In order to maintain heat conservation, the valve opening ratio between the first input end and the second input end can also be the second fluid temperature difference: the first fluid temperature difference.

[0100] Q = cmΔT Formula (1)

[0101] The above-mentioned c is the specific heat capacity, the above-mentioned m is the mass of the object, and the above-mentioned ΔT is the temperature change amount of the object.

[0102] Further, in the case where the container module includes the first target container and the buffer container, since the mixed fluid obtained after mixing the first temperature fluid and the second temperature fluid first flows into the buffer container, and the fluid in the first target container itself has a current temperature and is easily affected by the outside world, the target temperature difference can be used as the additional opening of the first input end of the first flow control module, that is, the ratio of the sum of the second fluid temperature difference and the target temperature difference (total temperature difference) to the first fluid temperature difference is determined as the opening ratio between the first input end and the second input end.

[0103] After that, according to the opening ratio, the first input end and the second input end in the first flow control module can be controlled to be opened, so that the current temperature of the fluid in the container module reaches the above target temperature.

[0104] In addition, in the embodiment of the present application, when the container module includes the first target container, the fluid in the first target container can also be automatically replaced. Specifically, when the execution body of the embodiment of the present application determines to replace the fluid in the first target container, the replacement duration can be obtained. The replacement duration refers to the duration required to complete one replacement of the fluid in the first target container.

[0105] As an optional implementation manner, the replacement duration can be set by the user through the visualization interface. Based on this, the execution body of the embodiment of the present application can obtain the above replacement duration through the visualization interface.

[0106] After that, according to the above replacement duration and the preset container volume of the first target container, the fluid replacement speed when replacing the fluid can be determined. Optionally, the above container volume can be divided by the above update duration to obtain the corresponding fluid replacement speed.

[0107] After that, according to the above fluid replacement speed, the opening degrees of the water inlet valve and the drain valve of the first target container can be determined, and the water inlet valve of the first target container can be controlled according to the above opening degree of the water inlet valve, and the drain valve of the first target container can be controlled according to the opening degree of the drain valve.

[0108] As an optional implementation manner, the corresponding relationship between the fluid replacement speed, the opening degree of the water inlet valve of the first target container, and the opening degree of the drain valve of the first target container can be stored in advance. Based on this, the opening degrees of the water inlet valve and the drain valve corresponding to the fluid replacement speed can be determined from the above corresponding relationship.

[0109] The technical solution provided by the embodiment of the present application obtains the target temperature set for the container module, determines the first fluid temperature of the first temperature fluid flowing into the container module by the first temperature fluid delivery module, the second fluid temperature of the second temperature fluid flowing into the container module by the second temperature fluid delivery module, and the current temperature of the fluid in the container module respectively. According to the above-mentioned target temperature, the above-mentioned first fluid temperature, the above-mentioned second fluid temperature, and the current temperature, determine the opening ratio between the first input end and the second input end of the first flow control module, and control the opening of the first input end and the second input end in the first flow control module according to the above-mentioned opening ratio, so that the current temperature of the fluid in the container module reaches the above-mentioned target temperature. In this technical solution, when controlling the fluid temperature of the container module in the fluid temperature control system, according to the target temperature and the current temperature set for the container module, and referring to the first fluid temperature of the first temperature fluid flowing into the container module and the second fluid temperature of the second temperature fluid, adjust the opening ratio of the first input end and the second input end of the first flow control module, so as to make the temperature of the fluid in the container module reach the target temperature by controlling the flow ratio of the first temperature fluid and the second temperature fluid. It adjusts the temperature of the second temperature fluid through the condensation module in the fluid temperature control system, and adjusts the temperature of the first temperature fluid through the heat absorption module, thereby adjusting the temperature of the container module by adjusting the flow ratio of the first temperature fluid and the second temperature fluid, realizing efficient and accurate control of the fluid temperature in the fluid temperature control subsystem by recovering the heat in the refrigerant subsystem, and thus realizing more energy-saving, safe and accurate control of the fluid temperature in the container.

[0110] See Figure 4 , which is a flowchart of an embodiment of another fluid temperature control method provided by the embodiment of the present application. Figure 4 The process shown in Figure 3 On the basis of the process shown, it describes how to adjust the capacity of the fluid in the first target container on the basis that the container module includes the first target container and the buffer container. As Figure 4 shown, the process may include the following steps:

[0111] Step 401, when it is determined that the current temperature in the first target container reaches the target temperature, determine whether the first fluid position in the buffer container is greater than or equal to a preset first buffer position threshold; if so, execute step 402; if not, execute step 406.

[0112] Step 402, compare the second fluid position of the first target container with a preset first container position threshold and a preset second container position threshold respectively; wherein, the above-mentioned first container position threshold is less than the above-mentioned second container position threshold.

[0113] Step 403: When it is determined that the position of the second fluid is greater than the above first container position threshold and less than the second container position threshold, control the water inlet valve of the first target container according to a preset water inlet valve opening degree, and control the drain valve of the first target container according to a preset drain valve opening degree.

[0114] Step 404: When it is determined that the position of the second fluid is less than or equal to the first container position threshold, control the water inlet valve of the first target container to the maximum opening degree, and control the drain valve of the first target container according to a preset drain valve opening degree.

[0115] Step 405: When it is determined that the position of the second fluid is greater than the above second container position threshold, control the water inlet valve of the first target container according to a preset water inlet valve opening degree, and control the drain valve of the first target container to the maximum opening degree.

[0116] The following is a unified description of Steps 401 to 405:

[0117] The above first fluid position refers to the position of the fluid in the buffer container within the buffer container.

[0118] The above first buffer position threshold refers to the preset position threshold corresponding to the fluid with the minimum capacity in the buffer container within the buffer container.

[0119] The above second fluid position refers to the position of the fluid in the first target container within the first target container.

[0120] The above first container position threshold refers to the preset minimum position threshold corresponding to the fluid with the minimum capacity in the first target container within the first target container.

[0121] The above second container position threshold refers to the preset maximum position threshold corresponding to the fluid with the maximum capacity in the first target container within the first target container.

[0122] In the embodiment of the present application, during the process of injecting the first temperature fluid and the second temperature fluid into the first target container in the container module to adjust the temperature of the fluid in the first target container, in order to more accurately adjust the capacity and temperature of the fluid in the first target container, the execution entity of the embodiment of the present application may first determine whether the current temperature of the fluid in the first target container reaches the above target temperature.

[0123] As an optional implementation manner, when it is determined that the current temperature in the first target container reaches the above target temperature, it may be determined whether the position of the fluid in the buffer container (hereinafter referred to as "the first fluid position" for easy distinction) is greater than or equal to a preset first buffer position threshold.

[0124] Optionally, when it is determined that the position of the first fluid is greater than or equal to the above-mentioned first buffer position threshold, it indicates that the fluid in the buffer container at this time exceeds the lowest limit in the buffer container. Therefore, the fluid position of the first target container (hereinafter referred to as the "second fluid position" for easy distinction) can be further determined, and the above-mentioned second fluid position is respectively compared with a preset first container position threshold and a preset second container position threshold. Among them, the above-mentioned first container position threshold is less than the above-mentioned second container position threshold, which can be respectively understood as the minimum position and the maximum position of the fluid position in the first target container.

[0125] As an exemplary embodiment, when it is determined that the above-mentioned second fluid position is greater than the above-mentioned first container position threshold and less than the second container position threshold, it indicates that the fluid capacity in the first target container at this time is within the preset range. Therefore, the water inlet valve of the first target container can be controlled according to the preset water inlet valve opening degree, and the drain valve of the first target container can be controlled according to the preset drain valve opening degree. The above-mentioned preset water inlet valve opening degree and drain valve opening degree can be the opening degrees of the water inlet valve of the first target container preset by the user.

[0126] As another exemplary embodiment, when it is determined that the second fluid position is less than or equal to the first container position threshold, it indicates that the fluid capacity in the first target container is low at this time. Therefore, the water inlet valve of the first target container can be controlled to the maximum opening degree, and the drain valve of the first target container can be controlled according to the preset drain valve opening degree to increase the fluid capacity in the first target container.

[0127] As yet another exemplary embodiment, when it is determined that the above-mentioned second fluid position is greater than the above-mentioned second container threshold, it indicates that the fluid capacity in the first target container is large at this time. Therefore, the water inlet valve of the first target container can be controlled according to the preset water inlet valve opening degree, and the drain valve of the first target container can be controlled to the maximum opening degree to reduce the fluid capacity in the first target container.

[0128] Optionally, when it is determined that the position of the first fluid in the buffer container is less than the preset first buffer position threshold, it indicates that the fluid capacity in the buffer container is low at this time, and the following step 406 can be continued.

[0129] Step 406: When it is determined that the first fluid position is less than the first buffer position threshold, control the opening degrees of the first input end and the second input end in the first flow control module according to the above-mentioned opening degree ratio.

[0130] Step 407: During the process of injecting fluid into the buffer container through the first flow control module, determine whether the first fluid position is greater than or equal to a preset second buffer position threshold; if so, execute Step 408; if not, execute Step 409. The above-mentioned second buffer position threshold is greater than the first buffer position threshold.

[0131] Step 408: Control the buffer container to inject fluid into the first target container for a preset duration.

[0132] Step 409: In the case where it is determined that the first fluid position is greater than or equal to the first buffer position threshold and less than the second buffer position threshold, return to execute Step 401.

[0133] The following is a unified description of Steps 406 to 409:

[0134] The above-mentioned opening ratio refers to the ratio of the valve opening between the first input end and the second input end in the first flow control module determined through Step 303.

[0135] The above-mentioned second buffer position threshold refers to the fluid position threshold corresponding to when the fluid in the buffer container reaches the maximum capacity preset in advance.

[0136] In the embodiment of the present application, in the case where it is determined that the first fluid position in the buffer container is less than the above-mentioned first buffer position threshold, it indicates that the fluid capacity in the buffer container is relatively low at this time. Therefore, the opening degrees of the first input end and the second input end in the first flow control module can continue to be controlled according to the determined opening ratio, so as to continue injecting fluid into the buffer container through the first flow control module.

[0137] Based on this, during the process of injecting fluid into the buffer container through the first flow control module, it is possible to determine in real time whether the first fluid position is greater than the preset second buffer position threshold.

[0138] Optionally, in the case where it is determined that the first fluid position is greater than the second buffer position threshold, it indicates that the fluid capacity in the buffer container is relatively large at this time. Therefore, the buffer container can be controlled to inject fluid into the first target container for a preset duration. At this time, the speed at which the buffer container injects fluid into the first target container is greater than the speed at which the buffer container injects fluid into the first target container. It is also possible to close both the first input end and the second input end in the first flow control module. The embodiment of the present application does not limit this. The above-mentioned preset duration is the preset injection duration of the buffer container into the first target container.

[0139] Optionally, in the case where it is determined that the first fluid position is greater than or equal to the first buffer position threshold and less than the second buffer position threshold, it is possible to continue to return to execute Step 401 to determine whether the current temperature of the fluid in the first target container reaches the target temperature.

[0140] In the technical solution provided by the embodiment of the present application, by presetting a first buffer position threshold when the fluid volume in the buffer container is the smallest and a second buffer position threshold when the fluid volume is the largest, as well as a first container position threshold when the fluid volume in the first target container is the largest and a second container position threshold when the fluid volume is the smallest, and comparing the first fluid position in the buffer container with the first buffer position threshold and the second buffer position threshold in real time, and comparing the second fluid position of the fluid in the first target container with the first container position threshold and the second container position threshold respectively, and adjusting the opening degrees of the water inlet valve and the drain valve of the first target container in real time according to the comparison results, so as to ensure that while controlling the temperature of the fluid in the first target container to be stable at the target temperature, the fluid positions in the buffer container and the first target container are stable within a preset range, improving the stability and safety of temperature regulation of the first target container.

[0141] See Figure 5 , which is a flowchart of an embodiment of another fluid temperature control method provided by the embodiment of the present application. Figure 5 The process shown in Figure 3 On the basis of the process shown, it describes how the first temperature fluid supply module specifically provides the first temperature fluid when the fluid temperature control system further includes a second target container and a second temperature fluid recovery module, and the first temperature fluid supply module includes a second flow control module, a first supply unit, and a second supply unit, the fluid in the second target container is heated by at least one condensation module, and the second temperature fluid recovery module is used to recover the third temperature fluid in the second target container and heat the first temperature supply unit. As Figure 5 shown, the process may include the following steps:

[0142] Step 501: After determining the first fluid temperature of the first temperature fluid flowing into the container module of the first temperature fluid delivery module, determine whether the first fluid temperature is less than a preset freezing temperature threshold. If so, execute step 502; if not, end the process.

[0143] Step 502: When it is determined that fluid is currently provided by the second supply unit, determine the target opening degree of the first input end in the second flow control module.

[0144] Step 503: Control the first input end of the second flow control module to open according to the target opening degree, so as to provide fluid for the first temperature fluid delivery module through the first supply unit and the second supply unit simultaneously.

[0145] The following is a unified description of steps 501 to 503:

[0146] The above-mentioned freezing temperature threshold refers to the pre-set temperature threshold at which the fluid may freeze, such as 0°C.

[0147] In the embodiments of the present application, through Figure 2 the system structure shown, the fluid temperature control system may further include a second target container and a second temperature fluid recovery module. The first temperature fluid supply module may include a second flow control module, a first supply unit, and a second supply unit. Among them, the fluid in the second target container is heated by at least one condensation module. The second temperature fluid recovery module can be used to recover the third temperature fluid in the second target container and heat the first temperature supply unit. For the specific description of this structure, reference can be made to Figure 2 the description in the shown system structure, which will not be elaborated here.

[0148] Based on this, since the heat absorption module can absorb heat for the first temperature fluid delivery module, that is, refrigerate, when the heat absorbed by the heat absorption module is too much, it is easy to cause the temperature of the first temperature fluid flowing out of the first temperature fluid delivery module to be lower than the freezing temperature threshold and freeze. In this regard, after the execution entity of the embodiments of the present application determines the first fluid temperature of the first temperature fluid flowing into the container module of the first temperature fluid delivery module, it can determine whether the first fluid temperature is less than the preset freezing temperature threshold.

[0149] Optionally, when it is determined that the first fluid temperature is less than the above-mentioned freezing temperature threshold, if the fluid is currently provided only by the second supply unit, the target opening of the first input end in the second flow control module can be determined. By controlling the target opening of the first input end in the second flow control module, the heated first supply unit can provide the first temperature fluid with a higher temperature for the first temperature fluid delivery module.

[0150] As an optional implementation manner, when determining the above-mentioned target opening, the maximum opening of the first input end in the second flow control module and the initial temperature of the second supply unit (hereinafter referred to as "initial first fluid temperature" for convenience of description) can be obtained first. Optionally, the initial first fluid temperature can be the pre-set initial temperature value of the second supply unit.

[0151] After that, the first temperature difference between the initial first fluid temperature and the first fluid temperature, and the second temperature difference between the initial first fluid temperature and the freezing temperature threshold can be determined.

[0152] Then, the temperature difference ratio between the first temperature difference and the second temperature difference can be determined, and the above-mentioned temperature difference ratio is multiplied by the above-mentioned maximum opening to obtain the target opening of the first input end in the second flow control module.

[0153] Based on the above target opening degree, the execution entity of the embodiment of the present application can open the first input end of the second flow control module according to the above target opening degree, so as to supply fluid to the first temperature fluid delivery module through the first supply unit and the second supply unit simultaneously.

[0154] In the technical solution provided by the embodiment of the present application, after determining the first fluid temperature of the first temperature fluid flowing into the container module in the first temperature fluid delivery module, it is determined whether the first fluid temperature is less than a preset freezing temperature threshold. If so, when it is determined that fluid is currently supplied through the second supply unit, the target opening degree of the first input end in the second flow control module is determined, and the first input end of the second flow control module is controlled to open according to the target opening degree, so as to supply fluid to the first temperature fluid delivery module through the first supply unit and the second supply unit simultaneously. In this technical solution, the third temperature fluid in the second target container heated by the refrigerant recovery subsystem is recovered and used to heat the first supply unit. Based on this, when the fluid temperature in the first temperature fluid delivery module reaches the freezing temperature threshold, the first supply unit and the second supply unit can be controlled to supply fluid simultaneously to increase the fluid temperature in the first temperature fluid delivery module and prevent the fluid in the first temperature fluid delivery module from freezing, thereby improving the safety when controlling the temperature of the container module.

[0155] To facilitate the understanding of the fluid temperature control system and its control method provided by the present application, the following is an example for illustration:

[0156] Refer to Figure 6 , which is a schematic structural diagram of another fluid temperature control system provided by the embodiment of the present application. Figure 6 The shown structure takes the refrigerant subsystem as the refrigerant circuit, the fluid temperature control subsystem as the fish tank water circulation, the fluid as water, the first supply unit as cold water inlet 1, the second supply unit as cold water inlet 2, the second flow control module as valve 1, the first flow control module as valve 2, the first temperature fluid delivery module as the fish tank cold water pipe, the second temperature fluid supply module as hot water inlet, the second temperature fluid delivery module as the fish tank hot water pipe, the first temperature measurement module for measuring the cold water outlet temperature of the fish tank cold water pipe, the second temperature measurement module for measuring the hot water outlet temperature of the fish tank hot water pipe, the buffer container as the buffer area, the first target container as the fish tank, the second target container as the water tank, the second temperature fluid recovery module as the waste water tank, the condensation module set including the primary condenser and the secondary condenser, the heat absorption module as the evaporator, and the refrigerant circuit further including the compressor and the throttling device as examples for illustration. As Figure 6 shown, the system structure can include: a refrigerant circuit part and a fish tank water circulation part.

[0157] Among them, the refrigerant circuit of the air - source heat pump water heater mainly consists of a compressor, a condenser, a throttling device, and an evaporator. The compressor provides power for the refrigerant cycle. The throttling device converts the refrigerant from a high - pressure state to a low - pressure state. The condenser releases heat to heat the liquid in the water tank, and the evaporator absorbs heat to absorb heat from the air. However, there is often still a lot of heat remaining in the refrigerant after passing through the condenser, and this part of the heat is dissipated into the air. Therefore, in the embodiment of this application, a secondary condenser is added to the refrigerant circuit to further recover the waste heat in the refrigerant, which can further reduce the refrigerant temperature after passing through the secondary condenser and improve the overall energy utilization rate.

[0158] Among them, for the fish - tank water - circulation part, in order to make the fish - tank temperature stable and controllable, the water circulation of the fish - tank is mainly divided into two parts: a hot - water pipe and a cold - water pipe. The controllability of the water temperature is achieved by controlling the inlet ratio of hot water and cold water:

[0159] First, for the hot - water pipe structure, it mainly absorbs heat from the secondary condenser for heating, and is equipped with a hot - water outlet temperature - sensing package for measuring the water temperature. Then, for the cold - water pipe part, the evaporator absorbs heat from it to lower the water temperature. The biggest difference between the cold - water pipe and the hot - water pipe is that it has two water inlets. One water inlet is for normal water intake, and the other is for water intake after heat exchange with wastewater first. The water intakes of both the cold - water pipe and the hot - water pipe are from external water sources, and only a heat - pump device is used for heat absorption and heat release.

[0160] Among them, the reason for the double water inlets of the cold - water pipe is to prevent the cold - water pipe from freezing and blocking the pipeline. The air - source heat pump has two operating states: low - power standby and rated - power heating during normal operation. Low - power standby is mainly to maintain the water - tank temperature to ensure hot water supply at any time. At this time, the compressor power is low, and the heat absorbed by the evaporator and the heat released by the condenser are both small. At this time, there is no risk of the cold - water pipe freezing. Rated - power heating is mainly because the hot water in the water tank is used, and the water - tank temperature is reduced, resulting in the compressor needing to increase power to produce hot water. Therefore, the heat throughput of the heat pump increases significantly. This causes the temperature of the condenser pipe to drop sharply below zero, and the cold - water pipe is prone to freezing. Since the heat in the refrigerant is mainly used for the primary condenser to heat the water tank, the temperature of the hot - water pipe varies little in the two states, so the hot - water pipe does not require special treatment.

[0161] Furthermore, the reason for the rated operation of the heat pump is that the hot water in the water tank is consumed, and there is still a lot of heat remaining in the used hot water. Therefore, in the embodiment of this application, the wastewater is collected to heat the water inlet of the cold - water pipe. This not only solves the problem of the cold - water pipe freezing but also further utilizes the waste heat in the wastewater.

[0162] In the embodiments of the present application, under normal conditions, cold water enters the cold water pipe normally. When the temperature of the cold water outlet is lower than the freezing threshold, the control valve 1 opens the water inlet on the waste water heating side to restore the normal temperature of the cold water outlet. The opening control formula of the control valve 1 is shown in the following formula (2):

[0163]

[0164] Among them, k above is the opening of the control valve 1, and T above 冷水实际 is the temperature of the cold water pipe measured actually; T 结冰 is the freezing threshold temperature; T 进水 is the temperature of the normal water inlet side of the cold water pipe, and a fixed default value can be taken; K is the maximum opening of the control valve 1.

[0165] Furthermore, if cold water and hot water are directly mixed, it is easy to make the water temperature change suddenly. Therefore, a buffer area for mixing cold water and hot water is set in the system structure provided by the embodiments of the present application. When the water temperature in the buffer area is stable, water supply to the fish tank will be carried out. The main goal of the buffer area is to make the cold water and hot water exchange heat fully, so that the final outlet water temperature is stable. The water inlet of the buffer area can adopt a spiral water inlet or a layered water inlet device to promote the uniform mixing of cold and hot water and avoid layering. The water outlet of the buffer area can use a porous water outlet plate or evenly distributed water outlet holes to ensure the smooth flow of water and avoid temperature fluctuations caused by too fast water outlet speed.

[0166] Regarding Figure 6 the fluid temperature control system shown, the following logical control can be carried out through Figure 7 the process shown. Refer to Figure 7 , which is the flowchart of another embodiment of the fluid temperature control method provided by the embodiments of the present application. As Figure 7 shown, this process can include the following steps:

[0167] First of all, for the water change of the fish tank, the user needs to set the water change cycle T 换水 of the fish tank, that is, how long it takes to change a tank of water. Assuming the volume of the fish tank is V 鱼缸 , the set water change speed v 换水 of the fish tank can be calculated as 鱼缸 = V 换水 / T 换水 . After that, the opening set by the user can be obtained according to v

[0168] to control the opening of the water inlet valve and the drain valve of the fish tank to control the regular water change of the fish tank. 设定 Secondly, for the temperature adjustment of the fish tank, first the user needs to set the water temperature T 冷水 of the fish tank, and then measure the outlet water temperatures T 热水 of the cold water pipe and the hot water pipe respectively, and calculate the difference ΔT 冷水 between them and the set water temperature.and ΔT 热水 。

[0169] After that, according to the specific heat capacity formula, the heat absorbed and released by the same volume of cold water and hot water when their temperatures reach T 设定 is C*ΔT 冷水 and C*ΔT 热水 . In order to maintain heat conservation, the valve opening ratio of the cold water pipe and the hot water pipe is ΔT 热水 : ΔT 冷水 .

[0170] After the above calculations, the control logic of the buffer water level and the fish tank temperature is entered: First, judge whether the fish tank temperature T 鱼缸 is equal to T 设定 . If not equal: Calculate the temperature difference ΔT 鱼缸 = T 鱼缸 - T 设定 , and ΔT 鱼缸 is used as the additional opening of the cold water pipe valve. At this time, the cold and hot water valve opening ratio is: (ΔT 热水 +ΔT 鱼缸 ): ΔT 冷水 .

[0171] After that, open the cold and hot water pipes according to the above ratio, and then judge whether the buffer water level exceeds the upper limit. If it exceeds the upper limit, the buffer water is drained into the fish tank for a period of time to lower the water level, because too high buffer water level will slow down the temperature regulation. Then judge the fish tank temperature T 鱼缸 again to see if it is equal to T 设定 . If not equal, repeat the above operations. If equal: Judge whether the buffer water level exceeds the lower limit. If it exceeds the lower limit, open the cold and hot water pipes according to the valve opening ratio to replenish water for the buffer; if it does not exceed the lower limit, the water in the buffer can be introduced into the fish tank, and the system enters the fish tank water level control logic: First, judge whether the fish tank water level exceeds the lower limit. If it exceeds the lower limit, the water inlet valve of the fish tank is opened at the maximum opening, and the water discharge valve of the fish tank is opened at the user-set opening; if it does not exceed the lower limit, then judge whether the fish tank water level exceeds the upper limit: If it exceeds the upper limit, the water discharge valve of the fish tank is opened at the maximum opening, and the water inlet valve of the fish tank is opened at the user-set opening; if the fish tank water level is normal, both the water inlet valve and the water discharge valve are opened at the user-set opening.
