Abstract
Description
An energy storage and heat release system Technical Field
[0001] This invention relates to the field of energy storage equipment, and more particularly to an energy storage and heat release system. Background Technology
[0002] Thermal energy storage devices can convert solar energy, electrical energy, waste heat, etc. into thermal energy of energy storage materials for storage, and release energy by exchanging heat with the energy storage materials through various external media.
[0003] Existing thermal energy storage devices use a single medium for heat release. For example, low-temperature thermal energy storage devices based on phase change materials such as lauric acid, palmitic acid, sodium acetate trihydrate, and xylitol can only produce hot water at 30°C to 80°C. They have the disadvantages of a single heat release method and low heat energy quality, and are only used to provide domestic hot water or heating. Solid thermal energy storage devices based on magnesium oxide use waste heat boilers for steam output, steam-water heat exchangers for hot water output, and heat pipe heat exchangers for hot air output. The auxiliary heat release system accounts for a large proportion of the volume, and a single heat storage body can only be configured with one medium for heat release.
[0004] The limited range of heat release modes in the aforementioned thermal energy storage devices severely restricts their effectiveness and application scope.
[0005] To address the aforementioned issues, Chinese patent CN101158508B proposes "a dual-purpose device for hot water and hot air using electrothermal metal phase change energy storage, comprising an electrothermal element, a metal phase change energy storage material, a double-layered sleeve, a shell container, and an insulation layer. The electrothermal element and the double-layered sleeve are directly placed within the metal phase change energy storage material, which is contained within the shell container, which is then wrapped with an insulation layer. The double-layered sleeve consists of an inner tube and an outer tube; the inner tube carries water or air, while the outer layer is the metal phase change energy storage material. During heating, the heat stored in the metal phase change energy storage material is transferred to the water or air inside the tube through the double-layered sleeve, obtaining hot water or hot air." However, this technical solution cannot provide parallel heat release for multiple media, and the double-layered sleeve cannot efficiently generate steam.
[0006] Although the Chinese patent CN118602581A filed by the applicant discloses that the heat release device may include a steam supply mechanism and a steam-water mixing component, the number of media is limited, and there is no connection between the multiple media during heat exchange, resulting in heat waste.
[0007] Therefore, there is a need for an energy storage and heat release system that can be based on multiple media simultaneously, which can effectively solve the problems of single heat release form, poor controllability, and low heat exchange efficiency of existing thermal energy storage devices, and improve the flexibility and versatility of thermal energy storage devices. Summary of the Invention

When the gas temperature is less than or equal to the seventh temperature threshold, the fourth temperature sensor generates a seventh control command to the gas blowing element to increase the power of the gas blowing element.

[0069] Referring to Figure 1, a schematic diagram of a heat storage and heat release system according to a preferred embodiment of the present invention is shown. In this embodiment, in order to simultaneously exchange heat with multiple media, the heat storage and heat release system includes a heat storage device and a heat release device. The heat storage device includes a charging section and a heat storage section 100. The charging section extends into the heat storage section 100 and provides energy, such as electrical energy, to the heat storage section 100. The heat storage section 100 converts the electrical energy into heat energy and stores it, thereby raising the temperature and achieving the effect of the charging section heating the heat storage section 100 and the heat storage section 100 storing heat. To complete the heat exchange, the heat storage section 100 is configured as follows: the heat storage section 100 includes a shell, the shell including an inner shell layer 102 and an outer shell layer 106. The inner shell layer 102 forms a heat storage cavity for accommodating the heat storage material 101, that is, the heat storage material 101 for storing heat is filled in the heat storage cavity. The outer shell 106 layer is separated from the inner shell 102, preferably forming a heat exchange interlayer 105 between the inner shell 102 and the outer shell 106 layer. The heat exchange medium can exchange heat with the heat storage material 101 through indirect contact within the heat storage cavity, or through indirect contact within the heat exchange interlayer 105. Therefore, it can be understood that the inner shell 102 can be made of a material with good thermal conductivity, while the outer shell 106 layer can be made of a material with poor thermal conductivity, so that the heat stored by the heat storage material 101 is retained as much as possible within the outer shell 106 layer.
[0070] As described above, in order to achieve simultaneous heat exchange of multiple media in the heat dissipation section 200, the heat dissipation device includes a liquid supply pipeline and a gas supply pipeline. The liquid supply pipeline carries a cool liquid medium supplied from the outside, such as various types of water (including but not limited to purified water, mineral water, tap water, etc.). The liquid supply pipeline extends into and out of the heat storage material 101, partially contacting the heat storage material. This allows the liquid medium flowing through the liquid supply pipeline to indirectly contact the heat storage material 101 (the contact is heat exchange between the heat storage material 101 and the pipe body of the liquid supply pipeline, with the pipe body being heated before exchanging heat with the liquid medium). As the liquid medium flows through the heat storage material 101, it absorbs heat. During this heat absorption process, as the temperature continuously rises, when it exceeds its boiling point, the temperature of the liquid medium reaches the phase change threshold and is converted into steam, completing the vaporization process and being discharged from the outlet of the liquid supply pipeline (or, if it does not reach the boiling point, it is converted into a hotter liquid medium and discharged). Thus, a cooler liquid medium is provided first, and a hotter steam is generated for heat exchange. In this embodiment, the aforementioned tube body can be a liquid heat exchange coil 104, which is spirally, staggeredly, or arranged in a planar manner within the heat storage material 101. To improve heat exchange efficiency, the heat storage material 101 can be configured such that the outlet of the liquid heat exchange coil is in a vapor state when the set heat release completion temperature is above the set temperature. More preferably, the vaporization process can be completed when the liquid is about to leave the heat storage material 101 from the supply pipeline, for example, by adjusting the flow rate of the supply pump 217, the temperature of the heat storage material 101, and the area of the heat exchange portion of the heat storage material 101, so that it turns into steam when it is about to flow out of the outlet.
[0071] On the other hand, the gas supply pipeline is used to provide cooler air or cold air. After being heated in the heat dissipation device, it provides warmer air or hot air to the outside. Preferably, the gas supply pipeline is connected to the heat exchange inlet 107 and heat exchange outlet 108 of the heat exchange jacket 105 (the positions of the heat exchange inlet 107 and heat exchange outlet 108 are not limited, as long as two openings are made at the location of the closed heat exchange jacket 105 to isolate it from the outside) (or in contact with the heat storage material in other ways). The gas supply pipeline is filled with a gas medium, so that after the gas medium enters from the gas supply pipeline, it will flow through the interior of the heat exchange jacket 105. During the flow, through indirect heat exchange with the heat storage material 101 (the heat of the heat storage material 101 is first exchanged to the inner shell, and the inner shell then provides heat to the gas medium in direct contact with it), the gas medium absorbs heat and is discharged.
[0072] With the above configuration, when users need to choose one or both of the heat-exchanged steam or hot air, they can start the above energy storage and heat release system to obtain the corresponding heat-exchanged medium as needed. Furthermore, by controlling the flow rate of the medium during the heat exchange process, the temperature range of the heat-exchanged steam can reach 100°C to 300°C, and the temperature range of the hot air can reach 60°C to 500°C.
[0073] In a preferred embodiment, the heat-charging section is an electric heating element and / or a photothermal heating element, including a heating body 111 and an electrical connection element 112. The heating body 111 is embedded within the heat storage section 100. The electrical connection element 112 can be a cable or a light source, with one end connected to the heating body 111 to provide electrical energy to the heating body 111, and the other end connected to a power source. With the above configuration, when an external power source is controlled to provide electrical energy to the heat-charging section, the electrical energy of the heat-charging section is converted into heat energy and transferred to the energy storage material until the temperature of the energy storage material reaches a preset temperature, thus completing heat storage. The thermal energy storage device also includes an outer shell 106, with the outer shell 106 and the inner shell layer 102 spaced apart and filled with insulation material to form an insulation interlayer 103, thereby confining the heat of the energy storage material within the outer shell 106 layer to prevent further leakage. Preferably, the insulation interlayer 103 can be made of insulating material or designed as a vacuum; structures and methods for blocking heat can be used in this invention.
[0074] To control the heat storage state of the heat storage material 101, its temperature will be controlled. Specifically, the heat storage material 101 is encapsulated within a heat storage cavity, and the encapsulation may be made of heat-insulating material to isolate the heat storage material 101 and its stored heat within the heat storage cavity. A first temperature sensor may also be installed inside the heat storage cavity. The first temperature sensor may be embedded inside the heat storage material 101, in direct contact with the heat storage material 101 to accurately collect its real-time temperature. The first temperature sensor may be wired, with the connected wires extending from inside the heat storage cavity and connecting to an external control module. When the first temperature sensor detects the heat storage temperature of the heat storage material 101, this temperature will be sent to the control module. Correspondingly, the control module has a first temperature threshold and a second temperature threshold preset, and the first temperature threshold is less than or equal to the second temperature threshold. When the heat storage temperature is lower than the first temperature threshold, it indicates that the temperature of the heat storage material 101 is low, and its total heat exchange capacity for gas and liquid media is small. It should be heated up in time. Therefore, the control module controls the power supply to turn on the power supply circuit to the heating body 111. After the heating body 111 is powered on, it gradually receives electrical energy and converts the electrical energy into heat energy again, and then exchanges the heat to the heat storage material 101. When the temperature of the heat storage material 101 gradually rises and its heat storage temperature is greater than or equal to the second temperature threshold, it indicates that the heat stored in the heat storage material 101 is sufficient. If the temperature continues to rise, there may be dangers such as overheating expansion and explosion. Or, for energy-saving considerations, it is not necessary to store too much heat in the heat storage material 101. Therefore, the control module controls the power supply to disconnect the power supply circuit to the heating body 111, and the heat storage material 101 gradually releases heat and cools down. In a preferred embodiment, the first temperature threshold can be 200°C and the second temperature threshold can be 600°C. Other configurations of the first and second temperature thresholds, such as 50°C-800°C or 300°C-400°C, can be adjusted according to actual working conditions and user requirements.
[0075] In addition to the above configuration, the power-on and power-off of the charging section of the heat storage material 101 can be configured without being limited to two temperature thresholds. For example, only one temperature threshold can be set. When the heat storage temperature of the heat storage material 101 reaches the temperature threshold, the further heating time is limited, or the power consumption of the charging section is gradually reduced within a preset time.
[0076] In a preferred embodiment, the liquid supply pipeline configuration includes a replenishment pipe 201, a supply tank 220, a supply pump 217, a supply valve, and a supply line. The replenishment pipe 201 is connected to a liquid source that provides the liquid medium, receiving the liquid medium, such as water, which can enter the liquid supply pipeline through the replenishment pipe 201. In a household environment, the replenishment pipe 201 can be a water pipe pre-embedded in the wall. The liquid supply tank 220, such as a water tank, is connected to the replenishment pipe 201 to receive and store the liquid medium. Its storage function acts as a buffer area, controlling the flow rate of the liquid medium into the supply pipeline. (In another embodiment, the liquid supply tank 220 can be used directly to store the liquid medium, and the liquid medium can be drawn out through the replenishment pipe 201.) The liquid supply pump 217 is connected to the liquid supply tank 220 through the liquid supply pump outlet 210 (a first flow sensor 226 can be installed at the liquid supply pump outlet 210 of the liquid supply pump 217 to detect the liquid supply flow rate). It draws in the liquid medium, meaning that when the suction capacity of the liquid supply pump 217 is controlled, the flow rate of the liquid medium into the supply pipeline can be precisely controlled. The liquid supply valve is located at the outlet of the liquid supply pump 217. When it is open, the supply pipeline is connected; when it is closed, the supply pipeline is shut off, thereby controlling the output state and output flow rate of the liquid supply pump 217. For more precise control of the liquid supply pump 217, the output flow rate can be adjusted by changing the input power. Meanwhile, the liquid supply valve allows the liquid medium to flow in one direction and prevents backflow; the liquid supply pipe includes an inlet end 110 and a steam outlet end. The inlet end 110 can be connected to the liquid supply valve through a liquid-state connector 211. After the liquid supply pipe extends into the heat storage material 101 and extends out to form the steam outlet end, it is connected to a gas-state connector 212 and continues to extend outward (or the heat storage material 101 itself has a liquid heat exchange coil 104, and the liquid heat exchange coil 104 is connected to the liquid supply pipe at the inlet end 110 and the steam outlet end, respectively. In this case, the liquid-state connector 211 serves as the inlet end 110 and is sealed and connected to the inlet of the liquid heat exchange coil, and the gas-state connector serves as the steam outlet end and is sealed and connected to the outlet of the liquid heat exchange coil), thereby forming the first heat exchange channel. With the first heat exchange channel, the liquid medium enters the heat storage chamber through the replenishment pipe 201, the supply tank 220, the supply pump 217, the supply valve, and the supply pipe in sequence. After exchanging heat with the heat storage material 101, it is discharged from the steam outlet. As mentioned above, the liquid medium entering from the liquid inlet 110 is the vaporized steam discharged from the liquid outlet 109. When the user needs to use high-temperature steam, it can be directly used by connecting it through the pipe from the liquid outlet 109.
[0077] To further utilize the discharged steam, the liquid supply pipeline also includes a proportional regulating valve 230 and a first solenoid valve 228. One end of the proportional regulating valve 230 is connected to the liquid inlet 110, and the other end is connected to the steam outlet via a water bypass pipe 213, and then to a steam main pipe 214. That is, the liquid inlet 110 is simultaneously connected to the proportional regulating valve 230 and the liquid supply pump 217. After flowing out of the liquid supply pump 217, the liquid medium flows in two branches: one enters the liquid supply pipe and exchanges heat with the heat storage material 101; the other enters the proportional regulating valve 230, does not exchange heat with the heat storage material 101, and maintains its original temperature. Thus, the proportional regulating valve 230 is used to adjust the flow rate into each branch. In other words, when more steam is needed, more liquid medium can be controlled to enter the liquid supply pipe; conversely, when too much steam is needed, the amount of liquid medium entering the liquid supply pipe can be controlled to decrease. When another diverted liquid medium that does not enter the supply pipe flows through the proportional control valve 230, it will come into contact with and mix with the steam discharged from the steam outlet. It can be understood that the discharged steam, having completed the heat exchange process, has a higher temperature and can be considered superheated steam, while the liquid medium that has not undergone heat exchange has a lower temperature. After mixing, the superheated steam will be cooled, while the liquid medium will be heated, resulting in vaporization. The final mixed medium will be saturated steam or ordinary steam with a temperature lower than the superheated steam. Saturated steam is steam at 100°C under one atmosphere of pressure, in a saturated state. Similarly, if the temperature of the mixed steam is higher than the temperature at which saturated steam is formed, the proportional control valve 230 can be adjusted to control less liquid medium entering the supply pipe; if the mixed medium does not form steam, the proportional control valve 230 can be adjusted to control more liquid medium entering the supply pipe. In addition, a first flow sensor can be installed at the outlet of the supply pump to detect the liquid flow rate at the pump outlet.
[0078] On the other hand, one end of the first solenoid valve 228 is connected to the steam outlet to receive steam, and the other end is connected to the steam pipe 204. The received steam will be transported to the steam pipe 204 for discharge. When the user's application scenario requires the use of higher temperature steam, the steam generated under this configuration can be utilized.
[0079] Further optionally, the liquid supply line also includes: a second temperature sensor 224 and / or a pressure sensor 225, located between the first solenoid valve 228 and the steam outlet, for monitoring the steam temperature and / or steam pressure, thereby monitoring whether the steam temperature meets the standard, and whether the steam pressure will affect the pipeline, or preventing overheated steam from damaging the seals (the accuracy of the steam temperature can also be indirectly verified by monitoring the steam pressure). Specifically, the second temperature sensor 224 is equipped with a third temperature threshold and a fourth temperature threshold, wherein the third temperature threshold is less than the fourth temperature threshold. When the steam temperature is less than or equal to the third temperature threshold, it indicates that the current saturated steam temperature is too low and needs to be increased. The second temperature sensor 224 then generates a first control command and sends it to the proportional regulating valve 230. After receiving the first control command, the proportional regulating valve 230 reduces the flow rate of the diverted liquid medium. This results in an increase in the flow rate of the liquid medium diverted to the supply pipe while the total amount of liquid medium output by the liquid pump 217 remains unchanged, and a decrease in the flow rate of the liquid medium diverted to the downstream end of the proportional regulating valve 230. As a result, more liquid medium is heat-exchanged to generate more steam, and less liquid medium is mixed with it. This results in more medium having a higher temperature during mixing, and the temperature of the mixed saturated steam will also be higher until the third temperature threshold is reached. On the other hand, when the steam temperature is greater than or equal to the fourth temperature threshold, it indicates that the current steam temperature is too high and needs to be reduced. The second temperature sensor 224 then generates a second control command and sends it to the proportional control valve 230, controlling the proportional control valve 230 to increase the flow rate of the diverted liquid medium. This results in a decrease in the flow rate of the liquid medium diverted to the supply pipe while keeping the total amount of liquid medium output by the liquid pump 217 constant. The flow rate of the liquid medium diverted to the downstream end of the proportional control valve 230 increases, resulting in less liquid medium being heat-exchanged and producing less steam. As a result, more liquid medium is mixed with the steam, leading to fewer media having higher temperatures during mixing. The temperature of the saturated steam after mixing will also be lower until the fourth temperature threshold is reached.
[0080] Considering the potential for temperature inaccuracies in the second temperature sensor 224, this embodiment will incorporate additional monitoring factors to determine whether the saturated steam meets the standard. Specifically, this additional monitoring factor is the pressure of the saturated steam. It is understood that steam pressure and temperature have a certain correlation when the volume remains constant. The pressure sensor 225 can be equipped with a first pressure threshold and a second pressure threshold, where the first pressure threshold is less than the second pressure threshold. When the steam pressure is less than or equal to the first pressure threshold, it indicates that the current saturated steam pressure is too low, and its temperature is also very likely to be low. The pressure sensor 225 generates a third control command and sends it to the proportional regulating valve 230, controlling the proportional regulating valve 230 to reduce the flow rate of the diverted liquid medium. This results in an increase in the flow rate of the liquid medium diverted to the supply pipe while the total amount of liquid medium output by the liquid pump 217 remains unchanged, and a decrease in the flow rate of the liquid medium diverted to the downstream end of the proportional regulating valve 230. As a result, more liquid medium is heat-exchanged to generate more steam, and less liquid medium is mixed with it. This results in more medium having a higher temperature during mixing, and the pressure of the mixed saturated steam will also be higher until it reaches the first pressure threshold, which means that the temperature of the saturated steam will also reach the desired value at this time. When the steam pressure is greater than or equal to the second pressure threshold, it indicates that the current steam pressure is too high, and its temperature is also very likely to be high. The pressure sensor 225 generates a fourth control command and sends it to the proportional regulating valve 230, which controls the proportional regulating valve 230 to increase the flow rate of the diverted liquid medium. This reduces the flow rate of the liquid medium diverted to the supply pipe while keeping the total amount of liquid medium output by the liquid pump 217 constant, and increases the flow rate of the liquid medium diverted to the downstream end of the proportional regulating valve 230. As a result, less liquid medium is exchanged for heat to produce less steam, and more liquid medium is mixed with it. This results in less medium having a higher temperature during mixing, and the pressure of the saturated steam after mixing will also be lower, until the second pressure threshold is reached, which means that the temperature of the saturated steam will also reach the desired value at this time.
[0081] To further utilize the steam, the energy storage and heat release system also includes a liquid outlet pipeline, used to further convert the steam into a liquid medium when the user requires a higher temperature liquid medium. The liquid outlet pipeline includes a second solenoid valve 229, one end of which is connected to the steam outlet to receive steam. After steam is formed, it also has two branches that can flow through it, namely, flowing in from the first solenoid valve 228 and the second solenoid valve 229 respectively. The steam flowing in from the first solenoid valve 228, as described above, will be discharged from the steam pipe 204 through a steam inlet pipe 215. The steam flowing in from the first solenoid valve 228 will be further utilized. The energy storage and heat release system also includes a heat exchanger 221, as shown in Figure 2. The heat exchanger 221 includes a steam inlet, a liquid inlet 202, a first liquid outlet 216, and a second liquid outlet 203. The steam inlet and the first liquid outlet 216 are connected to form a hot-side channel of the heat exchanger 221, while the liquid inlet 202 and the second liquid outlet 203 are connected to form a cold-side channel. Although the medium in the hot-side channel does not directly contact the medium in the cold-side channel, heat exchange will occur as the medium flows through the pipes in the heat exchanger 221. Specifically, the steam inlet and the first liquid outlet 203... Two solenoid valves 229 are connected. After receiving steam, the steam flows through the hot-side channel. The liquid inlet 202 is connected to a liquid source providing the liquid medium, receiving the liquid medium and allowing it to flow through the cold-side channel. After heat exchange between the steam and the liquid medium, the steam temperature decreases, liquefying back into the original liquid medium. This liquefaction temperature can be higher, lower, or equal to the initial temperature of the liquid medium. The liquid medium entering through the liquid inlet 202 will have its temperature increased after heat exchange, making it available for user use. Therefore, the first liquid outlet 216 discharges condensate, and this outlet can be connected to the liquid supply tank 220, allowing the condensate to be reused and repeatedly fed into the heat storage material 101. The second liquid outlet 203 discharges heated liquid medium for user use. A flow switch 231 can also be installed at the second liquid outlet 203 for user operation.
[0082] To ensure that the discharged heated liquid medium meets the user's expectations, the outlet pipeline will also detect the temperature of the discharged heated liquid medium. Specifically, the outlet pipeline also includes a third temperature sensor 222, located at the second outlet 203, which detects the temperature of the liquid medium to be discharged to form the outlet temperature. The third temperature sensor 222 has a preset fifth temperature threshold and a sixth temperature threshold, where the fifth temperature threshold is lower than the sixth temperature threshold. When the outlet temperature is less than or equal to the fifth temperature threshold, it indicates that the temperature of the discharged liquid medium is below expectations. The third temperature sensor 222 then sends a fifth control command to the feed pump 217 to increase its power. It is understood that after the power at the feed pump 217 is increased, if the proportional control valve 230 is not adjusted, the amount of steam generated will increase, resulting in more steam exchanging heat in the heat exchanger 221, thereby increasing the outlet temperature of the discharged liquid medium. When the outlet temperature is greater than or equal to the sixth temperature threshold, it indicates that the temperature of the discharged liquid medium is too high. The third temperature sensor 222 generates a sixth control command to the feed pump 217 to reduce its power. It is understood that after the power at the feed pump 217 is reduced, if the proportional control valve 230 is not adjusted, the amount of steam generated will decrease, resulting in less steam exchanging heat in the heat exchanger 221, thereby lowering the outlet temperature of the discharged liquid medium. Furthermore, when adjusting the power at the feed pump 217, the flow ratio of the proportional control valve 230 can also be adjusted simultaneously according to the operating conditions (e.g., whether the user side allows adjustment of the proportional control valve 230) to control the amount and temperature of steam.
[0083] In another optional embodiment, a liquid level element is provided in the liquid supply tank 220. The liquid level element has a preset liquid level threshold. When the capacity of the liquid medium stored in the liquid supply tank 220 is less than the liquid level threshold, a liquid source replenishes the liquid medium to the liquid supply tank 220, always ensuring that the liquid supply tank 220 has a certain amount of redundant liquid medium. Simultaneously, when the user needs to use hot steam or liquid medium, it is no longer necessary to start drawing liquid medium from scratch; the liquid medium can be directly obtained from the liquid supply tank 220.
[0084] In another optional embodiment, the heat storage material 101 is a phase change metal, such as an aluminum-silicon alloy. A phase change metal is a metal that is initially solid but melts and becomes liquid above a certain temperature. This change in the state of matter is called a phase change. The conditions for a metal phase change are temperature and pressure. Typically, two or more metals and non-metals are combined and used as an alloy. For example, carbon steel is an alloy composed of iron (Fe) and carbon (C). In addition to structural changes, the temperature at which an alloy changes its solid-solution or eutectic state upon temperature change is also called the phase change point.
[0085] In another optional embodiment, to provide heated air or hot air to the user, the air supply pipeline includes: an air inlet pipe 206 for receiving a gaseous medium, such as air in the usage scenario; an air blowing element 219, such as a blower, one end of which is connected to the air inlet pipe 206, and the other end of which is connected to the heat exchange inlet 107 via an air supply pipe 208. During operation, it draws in external air as the gaseous medium and delivers the gaseous medium to the heat exchange jacket 105. After the gaseous medium enters the heat exchange jacket 105 and exchanges heat with the heat storage material 101, its temperature rises; and an air outlet pipe 205, connected to the heat exchange outlet 108 via a return air pipe 207, receives the heat-exchanged gaseous medium and discharges it. With the above configuration, the user can receive hot air using this energy storage and heat release system, and can utilize the received hot air in usage scenarios such as hair dryers or heaters.
[0086] Furthermore, to allow for adjustable temperature of the heat-exchanged gas medium, the gas supply pipeline also includes: a mixing pipe 209, one end connected to the inlet pipe 206 and the other end connected to the outlet pipe 205, so that a portion of the gas medium drawn in by the blowing element 219 will not enter the heat exchange jacket 105; a mixing element 218, such as a mixing fan, connected between the mixing pipe 209 and the outlet pipe 205, diverting the gas medium entering through the inlet pipe 206 and controlling the gas flow rate entering the outlet pipe, so that a portion of the gas medium, after passing through the mixing pipe 209 and the mixing element 218, comes into contact with the heat-exchanged gas medium, and the two mix. The lower-temperature gas medium is then discharged mixed with the heat-exchanged gas medium. In this configuration, the amount of the lower-temperature gas medium mixed determines the final temperature of the discharged gas medium. Therefore, adjusting the amount of the lower-temperature gas medium mixed will adjust the final temperature of the discharged gas medium.
[0087] Specifically, the gas supply pipeline also includes a fourth temperature sensor 223, located at the outlet pipe 205, which detects the temperature of the gas medium after heat exchange to form the gas temperature. The fourth temperature sensor 223 has a seventh temperature threshold and an eighth temperature threshold, where the seventh temperature threshold is lower than the eighth temperature threshold. When the gas temperature is less than or equal to the seventh temperature threshold, it indicates that the temperature of the discharged gas medium is low and needs to be increased. The fourth temperature sensor 223 then generates a seventh control command to the blowing element 219 to increase the power of the blowing element 219 and draw in more gas medium. With the mixing element 218 not adjusted, more gas medium is drawn into the heat exchange jacket 105 for heat exchange, resulting in more high-temperature gas medium mixing with low-temperature gas medium, ultimately raising the temperature of the mixed gas. When the gas temperature is greater than or equal to the eighth temperature threshold, it indicates that the temperature of the discharged gas medium is too high and needs to be reduced. The fourth temperature sensor 223 generates an eighth control command to the blowing element 219 to reduce the power of the blowing element 219 and draw in less gas medium. With the mixing element 218 not adjusted, less gas medium is drawn into the heat exchange jacket 105 for heat exchange, resulting in less high-temperature gas medium mixing with low-temperature gas medium, ultimately reducing the temperature of the mixed gas.
[0088] Preferably or optionally, the gas supply line further includes: a second flow sensor 227, located at the intake pipe 206, for detecting the intake flow rate of the gas medium; the second flow sensor 227 has a first flow threshold and a second flow threshold, wherein the first flow threshold is less than the second flow threshold. When the intake flow rate is less than or equal to the first flow threshold, it indicates that too little gas medium is being drawn in, and the second flow sensor 227 generates a ninth control command to the mixing element 218 to increase the power of the mixing element 218, thereby controlling the mixing element 218 to draw in more gas medium. Conversely, when the intake flow rate is greater than or equal to the second flow threshold, it indicates that too much gas medium is being drawn in, and the second flow sensor 227 generates a tenth control command to the mixing element 218 to decrease the power of the mixing element 218, thereby controlling the mixing element 218 to draw in less gas medium. Understandably, one might typically consider controlling the amount of gas medium drawn in by the aeration element 219. However, in this embodiment, it is controlled by the mixing element 218. The amount of gas medium drawn in can be increased first, and then the power of the aeration element 219 controls the temperature of the discharged gas medium. Both control the parameters of different gas media. With this configuration, a high-temperature gas medium can be output at a constant flow rate and temperature.
[0089] When the preferred methods are used simultaneously, from the user's perspective, steam heat release, hot water heat release, and high-temperature gas heat release can be used simultaneously, resulting in a rich variety of heat exchange media. Furthermore, the threshold values in each embodiment can be configured with an upper and lower hysteresis difference to slightly expand the threshold judgment range and prevent the ping-pong effect.
