Description

Technical Field

[0001] The present invention relates to the field of indoor temperature control technology, and in particular to an intelligent temperature control system utilizing electrothermal conversion and phase change energy storage. Background Art

[0002] The existing indoor floor heating method usually uses copper pipes or PVC plastic pipes with hot water buried under the indoor floor or tiles for heating. The same is true for cooling, usually using air conditioning to cool the entire room. However, when there is no one in the room, the above method will cause energy waste. Therefore, in the case of advocating green and low-carbon, an automatic cooling or heating system is needed, which can automatically control the temperature of the system according to the needs of indoor occupants to achieve resource rationalization and maximum utilization.

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

[0004] The temperature control system changes temperature according to the set temperature. It will heat or cool quickly during the startup process, and will also quickly cool down or heat up after stopping. Sudden and rapid temperature changes will make the user experience worse.

[0005] Most automatic temperature control systems are controlled according to the set temperature. While maintaining the temperature, it will also cause excess energy loss. In addition, electricity prices have peaks and troughs. If they are only turned on when the electricity price is low and turned off when the electricity price is high, although costs can be saved, the user's demand for temperature cannot be met, so cost and comfort cannot be achieved at the same time.

[0038] The above summary is only for the purpose of the specification and is not intended to be limiting in any way.

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In the drawings, unless otherwise specified, the same reference numerals throughout the several views represent the same or similar components or elements. 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.

[0040] Figure 1 A schematic connection diagram showing the overall structure of the intelligent temperature control system according to an embodiment of the present invention is shown. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] In the following text, only some exemplary embodiments are briefly 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 accompanying drawings and description are considered to be exemplary in nature and not restrictive.

[0042] An embodiment of the present invention provides an intelligent temperature control system using electrothermal conversion and phase change energy storage. Refer to Figure 1 As shown, the intelligent temperature control system includes a first phase change structure 100, a second phase change structure 300, and an intelligent temperature control system 200.

[0043] The first phase change structure 100 and the second phase change structure 300 are arranged on the building body. The temperature at which the first phase change structure 100 undergoes a phase change is the first phase change temperature, and the temperature at which the second phase change structure 300 undergoes a phase change is the second phase change temperature.

[0044] The intelligent temperature control system 200 includes a temperature detection device 210, an intelligent control system 220, a heating device 231, and a cooling device 232. 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 first phase change temperature and the second phase change temperature. The intelligent control system 220 is electrically connected to the heating device 231 and the cooling device 232 respectively. When the real-time temperature is less than the first phase change temperature, the intelligent control system 220 controls the heating device 231 to start. When the real-time temperature is greater than the second phase change temperature, the intelligent control system 220 controls the cooling device 232 to start.

[0045] Wherein, the maximum heating temperature after the heating device 231 starts and the minimum cooling temperature after the cooling device 232 starts are both between the first phase change temperature and the second phase change temperature. Moreover, the maximum heating temperature after the heating device 231 starts does not exceed the second phase change temperature, and the minimum cooling temperature of the cooling device 232 does not fall below the first phase change temperature, so that the two systems will not have an impact on each other.

[0046] In this embodiment, the intelligent refrigeration system uses the temperature at which the phase change structure undergoes a phase change as the control temperature. While changing the temperature, it can use the phase change material for energy storage and release to smooth out the temperature change of the temperature control system and provide a better user experience. The intelligent refrigeration system can also be selected to start when the electricity price is low for gentle cooling and release energy from the phase change structure. When the electricity price is high, the intelligent refrigeration system shuts down and uses the phase change structure to absorb energy and delay the temperature rise, thus achieving low-cost electricity cooling and using the phase change structure to delay the temperature rise at high electricity prices, realizing further energy savings. The intelligent heating system uses the temperature at which the phase change structure undergoes a phase change as the control temperature. While changing the temperature, it can use the phase change material for energy storage and release to smooth out the temperature change of the temperature control system and provide a better user experience. The intelligent heating system can also be selected to start when the electricity price is low for gentle heating and store energy in the phase change structure. When the electricity price is high, the intelligent heating system shuts down and uses the phase change structure to release energy and release the heat stored during the low valley electricity price to slow down the temperature drop, thus realizing the release of the energy generated at low electricity prices at high electricity prices and achieving further energy savings.
