Description

Technical Field

[0001] The present invention relates to the technical field of intelligent temperature control, and particularly to an intelligent heating system using electrothermal conversion and phase change energy storage. Background Art

[0002] The existing indoor floor heating supply method usually heats by laying copper pipes or PVC plastic pipes with hot water buried under the indoor floor or tiles. The same is true for refrigeration, and air conditioners are usually used for full indoor refrigeration. However, when there is no one in the room, the above methods will cause waste of energy. Therefore, in the context of advocating green and low-carbon, an automatic refrigeration or heating system is needed, which can automatically control the temperature change of the system according to the needs of indoor personnel to achieve rational and maximum utilization of resources.

[0003] However, most temperature control systems have the following problems:

[0004] The temperature control system changes the temperature according to the set temperature. During the startup process, it will quickly heat or cool, and will also quickly cool or heat up after stopping. The sudden rapid temperature change will make the user experience worse;

[0005] Most automatic control temperature changes are controlled according to the set temperature. While maintaining the temperature, it will also cause unnecessary energy loss. Moreover, there are peak and valley prices for electricity. If it is only turned on when the electricity price is low and turned off when the electricity price is high, although the cost can be saved, the user's temperature requirements cannot be met, so the cost and comfort cannot be both achieved.

BRIEF DESCRIPTION OF THE DRAWINGS

These drawings are not necessarily drawn to scale. It should be understood that these drawings only depict some embodiments disclosed in accordance with the present invention and should not be regarded as limiting the scope of the present invention.

[0029] Figure 1 A connection schematic diagram showing the overall structure of the intelligent heating system according to an embodiment of the present invention is shown. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0031] This embodiment provides an intelligent heating system that utilizes electrothermal conversion and phase change energy storage. Refer to Figure 1 As shown, the intelligent heating system includes a phase change structure 100 and an intelligent temperature control system 200.

[0032] The phase change structure 100 is disposed on the building body, and the temperature at which the phase change structure 100 undergoes a phase change is the phase change temperature. When the phase change structure undergoes a phase change, it stores and releases energy.

[0033] The intelligent temperature control system 200 includes a temperature detection device 210, an intelligent control system 220, and a heating device 230; the temperature detection device 210 is used to measure the real-time temperature inside the building; the temperature detection device 210 is connected to the intelligent control system 220, and the intelligent control system 220 is used to receive the measured real-time temperature and compare it with the phase change temperature. The intelligent control system 220 is electrically connected to the heating device 230. When the real-time temperature is lower than the phase change temperature, the intelligent control system 220 controls the heating device 230 to start. When the real-time temperature rises to the phase change temperature, the phase change structure has undergone phase change energy storage. When the heating device 230 is turned off, the phase change structure will release the stored heat, which can not only extend the heating time but also slow down the temperature drop rate.

[0034] In this embodiment, the intelligent heating system uses the temperature at which the phase change structure undergoes a phase change as the control temperature. While the temperature changes, the phase change material can be used for energy storage and release to smooth the temperature change of the temperature control system and provide a better user experience. The intelligent heating system can also be selected to start at a low electricity price for gentle heating and energy storage of the phase change structure. When the electricity price is high, the intelligent heating system is turned off and the phase change structure releases energy, and the heat stored at the low valley electricity price is released to slow down the temperature drop. In this way, the energy generated at a low electricity price is released at a high electricity price, achieving further energy conservation.

[0035] In a specific embodiment, see Figure 1 As shown, the intelligent temperature control system 200 further includes a human body detector 240. The human body detector 240 is used to detect whether there is someone inside the building. The human body detector 240 is communicatively connected to the intelligent control system 220. The intelligent control system 220 is used to receive the detection signal of the human body detector 240. When the human body detector 240 outputs a signal indicating someone is present, the intelligent control system 220 is used to control the heating device 230 to start and heat to the set temperature. In this way, accurate temperature control according to user dynamics can be achieved.

[0036] In a specific embodiment, the intelligent control system 220 is used to start or stop according to the factor information affecting the electricity price. Further, the intelligent control system 220 is used to start or stop according to the factor information affecting the electricity price, including:

[0037] When the factor information is electricity price information, the intelligent control system 220 stops when the real-time electricity price is higher than the set electricity price, and the intelligent control system 220 starts when the real-time electricity price is less than or equal to the set electricity price.

[0038] When the factor information is self-generated electricity information, the intelligent control system 220 starts when there is self-generated electricity output, and the intelligent control system 200 stops when there is no self-generated electricity input.

[0039] When the factor information is electricity spot trading information, the intelligent control system 220 stops when the electricity trading price is higher than the average electricity trading price in the market, and the intelligent control system 220 starts when the electricity trading price is less than or equal to the average electricity trading price in the market.

[0040] In this embodiment, the intelligent heating system can also be selected to start at low electricity prices for gentle heating and store energy in the phase change structure. The intelligent heating system is turned off at high electricity prices to utilize the energy released by the phase change structure, and the heat stored at low valley electricity prices is released to slow down the temperature drop. In this way, the energy generated at low electricity prices is released at high electricity prices, achieving further energy conservation.

[0041] In a specific embodiment, refer to Figure 1 As shown, the intelligent temperature control system 200 further includes a forced start device 250 and a temperature limit device 260. The forced start device 250 is connected to the intelligent control system 220, the forced start device 250 is connected to the human body detector 240, and the temperature limit device 260 is connected to the heating device 230.

[0042] When the forced start device 250 receives a detection signal from the human body detector 240 indicating that there is someone, the forced start device 250 is used to keep the intelligent control system 220 in an always-on state to control the heating device 230 to be in a forced start state; when the heating device 230 is in a forced start state, the temperature limit device 260 is used to reset the maximum heating temperature of the heating device 230 according to the factor information affecting the electricity price.

[0043] Further, the temperature limit device 260 is used to reset the maximum heating temperature of the heating device 230 according to the factor information affecting the electricity price, including:

[0044] When the factor information is electricity price information, the temperature limit device 260 is used to control the heating device 230 to lower the maximum heating temperature when the real-time electricity consumption price is higher than the set electricity consumption price, and the temperature limit device 260 is used to control the heating device 230 to raise the maximum heating temperature when the real-time electricity consumption price is less than or equal to the set electricity consumption price.

[0046] When the factor information is electricity spot trading information, the temperature limiting device 260 is used to control the heating device 230 to reduce the maximum heating temperature when the electricity trading price is higher than the average electricity trading price in the market, and the temperature limiting device 260 is used to control the heating device 230 to increase the maximum heating temperature when the electricity trading price is less than or equal to the average electricity trading price in the market.

[0047] In a specific embodiment, referring to Figure 1 As shown, the intelligent temperature control system 200 further includes a temperature compensator 270. The temperature compensator 270 is used to measure the outdoor temperature. The temperature compensator 270 is used to generate a compensation signal according to the outdoor temperature. The temperature compensator 270 is connected to the intelligent control system 220. The intelligent control system 220 is used to perform temperature compensation on the real-time temperature according to the compensation signal: The intelligent control system 220 is used to compare the compensated real-time temperature with the phase change temperature to control the start or stop of the heating device 230.

[0048] Further, the intelligent control system 220 is used to compare the compensated real-time temperature with the phase change temperature to control the start or stop of the heating device 230, including:

[0049] When the outdoor temperature is lower than the set temperature, the temperature compensator 270 generates a low-temperature compensation signal. The intelligent control system 220 is used to reduce the real-time temperature by a compensation value when receiving the low-temperature compensation signal. The intelligent control system 220 is used to compare the real-time temperature after reducing the compensation value with the phase change temperature. If the real-time temperature after reducing the compensation value is less than the phase change temperature, the intelligent control system 220 controls the heating device 230 to start.

[0050] When the outdoor temperature is higher than the set temperature, the temperature compensator 270 generates a normal-temperature compensation signal. The intelligent control system 220 is used to increase the real-time temperature by a compensation value when receiving the normal-temperature compensation signal. The intelligent control system 220 is used to compare the real-time temperature after increasing the compensation value with the phase change temperature. If the real-time temperature after increasing the compensation value is less than the phase change temperature, the intelligent control system 220 controls the heating device 230 to start.
