Description

[0002] With the continuous growth of global energy demand and the enhancement of environmental protection awareness, finding efficient and sustainable ways to utilize energy has become an important issue at present. Phase Change Thermal Energy Storage (PCTES) is an efficient way to store thermal energy. By using phase change materials (PCM) to absorb or release a large amount of heat during the phase change process, it can effectively balance the contradiction between heating demand and energy supply. This technology has been widely used in renewable energy systems, building heating, cooling and cogeneration.

[0003] However, the existing phase change heat storage system still has some shortcomings in practical applications. First, traditional phase change heat storage systems often rely on complex mechanical and electronic control devices for temperature control, which increases the complexity and maintenance cost of the system. Secondly, the temperature control lag in the existing technology may lead to energy waste or insufficiency, affecting the stability and comfort of heating. In addition, the existing phase change heat storage system lacks an intelligent control mechanism in the use of heat pipes, and cannot be dynamically adjusted according to actual load requirements, resulting in the energy efficiency of the system not being fully utilized.

[0038] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0039] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0040] Reference Figure 1 This embodiment provides a heating control system, including a heating component 1, a temperature control component 2 and a protection component 3. The heating component 1 and the temperature control component 2 cooperate to achieve heating inside the room. The heating component 1 is mainly used to absorb heat from the outside through the evaporator 12 to heat the system. The evaporator 12 generally adopts a shell and tube heat exchanger. The condenser 13 is used to extract heat from the system to cool the system. The condenser 13 generally adopts a shell and tube heat exchanger. When in use, it is usually divided into two states: heat storage and heat release:

[0041] During heat storage: the evaporator 12 is turned on and the condenser 13 is turned off. At this time, the working medium in the tube is heated in the loop and becomes a vapor state. Under the action of buoyancy, it flows to the phase change storage tank 11. The working medium condenses into a liquid phase in the phase change storage tank 11 and flows back to the evaporator 12, forming a closed cycle.

[0042] When releasing heat: close the evaporator 12 and open the condenser 13. At this time, the working medium in the tube condenses into a liquid phase at the condenser 13, flows back to the phase change storage tank 11, is heated to become a vapor state, and flows into the condenser 13 under the action of buoyancy, forming a closed cycle.

[0043] Specifically, the heating component 1 includes a phase change storage tank 11, an evaporator 12, and a condenser 13 connected to the evaporator 12;

[0044] The input end and the output end of the phase change storage tank 11 are respectively connected to the evaporator 12 and the condenser 13;

[0045] Preferably, the temperature control component 2 includes a circulation pump 21 connected to the condenser 13 and a pipeline 22 connected to the circulation pump 21, and the circulation pump 21 is used to extract part of the liquid to exchange heat with the condenser 13;

[0046] Preferably, the protection assembly 3 includes a sensing element 31 and a deicing element 32 in communication with the condenser 13;

[0047] The de-icing element 32 is used to melt ice from the pipeline 22 .

[0048] Reference Figure 2-3 As an optional embodiment, specifically, the phase change storage tank 11 is filled with a phase change material; and the connecting pipe 14 between the condenser 13 and the evaporator 12 is filled with a refrigerant, which is used for the cooling and heating cycle of the system. The selection of the phase change material is determined based on the use conditions, such as paraffin, sugar alcohol and other substances. However, after the material is fixed, the phase change point is fixed.

[0049] Preferably, the evaporator 12 and the condenser 13 are both provided with a receiver capable of receiving the signal of the sensor 31 ; the receiver controls the switch of the evaporator 12 and the condenser 13 according to the signal of the sensor 31 .

[0050] Preferably, the pipeline 22 includes a water inlet pipe 220 connected to the circulation pump 21, and the water inlet pipe 220 is provided with a branch pipe 221 connected to the heat dissipation fin 222;

[0051] The heat dissipation fins 222 are communicated with a water outlet pipe 223 , and a heat network valve 224 is provided on the water outlet pipe 223 . The heat network valve 224 is also controlled by a signal from the sensor 31 .

[0052] Preferably, the sensing element 31 includes a first temperature measuring point 310 disposed indoors and a second temperature measuring point 311 disposed outdoors;

[0053] When the measured value of the first temperature measuring point 310 is higher than 22 degrees Celsius, the heating network valve 224 is controlled to be closed;

[0054] When the measured value of the first temperature measuring point 310 is lower than 22 degrees Celsius, the heating network valve 224 is controlled to open.

[0055] Preferably, the induction element 31 further includes a plurality of third temperature measuring points 312 disposed on the phase change storage tank 11. When the average value of the plurality of third temperature measuring points 312 is equal to the phase change point of the phase change material, the circulation pump 21 is controlled to start;

[0056] When the average value of the third temperature measurement points 312 is less than the phase change point of the phase change material, the circulation pump 21 is controlled to be turned off;

[0057] When the average value of the third temperature measurement points 312 is greater than the phase change point of the phase change material, the evaporator 12 is controlled to stop being heated;

[0058] When in use, water enters the water inlet pipe 220, and a portion of the water will first flow into the condenser 13, where the input water flow is heated by the steam, and then returns to intersect with the water flow in the branch pipe 221, and finally flows to the heat dissipation fins 222, heating the room, and then flows out through the water outlet pipe 223.

[0059] Preferably, the de-icing member 32 comprises a delivery pipe 320 respectively connected to the water inlet pipe 220 and the water outlet pipe 223 and a switch valve 321 for controlling the flow of the delivery pipe 320;

[0060] The switch valve 321 is controlled by the second temperature measuring point 311 .

[0061] Preferably, the de-icing component 32 also includes a pressurized nozzle 322 arranged on one side of the switch valve 321, and the injection position of the pressurized nozzle 322 is opposite to the turbine 323, and the rotation of the turbine 323 drives the generator 324 to transmit electricity. The turbine 323 has only one air inlet and one air outlet, and the air inlet is opposite to the injection position of the pressurized nozzle 322.

[0062] Preferably, the de-icing member 32 further includes a heat pipe 325 disposed inside the water inlet pipe 220 and the water outlet pipe 223, the outer wall of the heat pipe 325 is surrounded by a heating ring 326, the heating ring 326 is electrically connected to the generator 324, and the heat pipe 325 is in communication with the delivery pipe 320;

[0063] When in use, whether ice forms inside the water inlet pipe 220 and the water outlet pipe 223 depends on the material of the water inlet pipe 220 and the water outlet pipe 223. When the temperature of the second temperature measuring point 311 exceeds the temperature at which ice can form inside the water inlet pipe 220 and the water outlet pipe 223, the switch valve 321 is opened, so that steam is transported to the water inlet pipe 220 and the water outlet pipe 223. After passing through the pressurized nozzle 322, the ejected steam not only contains heat, but also drives the worm gear 323 to rotate, and drives the generator 324 to generate electricity to the heating ring 326, so that the heating ring 326 heats the surrounding ice area. At the same time, the steam not only plays a preheating role, shortening the heating time of the heating ring 326, but also the steam passing through the worm gear 323 will continue to be input to the heat pipe 325. Therefore, at this time, the steam and the heating ring 326 are combined to melt the ice synchronously.

[0064] Preferably, in the power-off state, the user can turn the system on and off by himself according to the temperature display of the temperature measuring point. This operation is mainly to prevent power outages or system failures, so that emergency manual operation can be performed. It does not rely entirely on system control and is mixed with human intervention, so that the safety of the overall system can be further guaranteed.

[0065] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
