Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular to an energy storage wall, system and method with cold, heat and electricity flexible resource regulation capabilities. Background Art

[0002] Under the background of global green and low-carbon development, the power system has gradually shifted from the traditional deterministic one-way power balance of "source follows load" to a highly uncertain energy supply system with new energy as the main body. The randomly fluctuating energy supply and consumption system of the new power system has shaped a new form of power-energy dynamic balance with two-way interaction between source and load, and the system's demand for flexible resources has increased significantly. As the main power consumer, the construction industry accounted for 36% of global terminal energy consumption and 37% of energy-related carbon dioxide emissions in 2020. The existing air-conditioning system uses electricity as it is used from the power grid, and electricity is often used during peak hours, which easily causes heavy overload of the power grid and high electricity costs. Therefore, how to improve the energy characteristics of the air-conditioning system through flexible regulation of cold, heat and electricity is of great significance to reducing building energy costs and saving energy and reducing carbon emissions.

[0003] At the same time, the current thermal design of building envelope structures uses the method of "insulation" to simply block the flow of indoor and outdoor heat. Although it avoids the adverse effects of climate, this simple and crude method of blocking indoor and outdoor heat flow increases the energy consumption of the air-conditioning system, which is a high-energy consumption and high-emission path. Building thermal design needs to shift from the crude blocking of indoor and outdoor heat flow to how to achieve the orderly flow and storage of indoor and outdoor heat flow, thereby forming a refined and low-carbon emission building thermal design method. At present, some scholars have proposed some technical ideas. For example, heat pipe embedded wall, the document [Yang Ying, Guan Qiman, Liu Wei, Liu Hao, Shen Yan, Wu Zhe, Liu Xiaoli, Zhang Yi. A container enclosure structure using heat pipes for heat dissipation [P]. Jiangsu Province: CN108966604B, 2020-06-12.], proposed a container enclosure structure using heat pipes for heat dissipation, placing the heat absorbing end and the heat releasing end of the heat pipe in the enclosure structure, enhancing the radiation and convection heat dissipation from the environment inside the container to the environment outside the box, and reducing the cooling energy consumption of the container-type computer room. The document [Zhang Z, Sun Z, Duan CA new type of passive solar energy utilization technology—The wall implanted with heat pipes [J]. Energy and buildings, 2014, 84: 111-116] analyzes the energy-saving benefits brought by the insertion of heat pipes in the exterior walls of traditional buildings.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The first purpose of the present invention is to provide an energy storage wall with the ability to adjust cold, heat and electricity flexible resources. It cooperates with energy storage materials, air ducts and heat pipes, and uses heat pipes to exchange heat between energy storage materials and temperature-controlled spaces to control temperature and reduce energy consumption.

[0006] The second purpose of the present invention is to provide a low-carbon environmental control system, which uses a self-generated power supply to power the temperature control component. When the power is sufficient, the temperature control component stores energy in the energy storage material. When the power is scarce, the energy storage material controls the temperature of the temperature control space, thereby reducing energy consumption, saving energy and reducing emissions.

[0007] The third object of the present invention is to provide a low-carbon environmental control method, which performs environmental control by using the above-mentioned low-carbon environmental control device. The method has simple steps, is easy to operate, and can effectively reduce building energy consumption.

[0008] In order to achieve the above object, the present invention particularly adopts the following technical solutions:

[0009] The present invention provides an energy storage wall with cold, heat and electricity flexible resource regulation capability, which is used to enclose a temperature-controlled space. The energy storage wall comprises:

[0010] Wall structure: energy storage material is arranged inside the wall;

[0011] Air duct: The air duct is arranged on both sides of the wall structure, and the air duct is connected with the temperature control space;

[0012] Heat pipe: one end of the heat pipe is fixed in the energy storage material in the wall structure, and the other end is exposed from the wall structure. The other end of the heat pipe is arranged in the air duct.

[0013] Preferably, an energy storage frame is provided in the wall structure, and the energy storage frame is formed by metal plates connected vertically and horizontally. The energy storage material is arranged in the energy storage frame, and the working temperature of the energy storage material is lower than the temperature of the temperature control space. The energy storage material controls the temperature of the temperature control space through the heat pipe.

[0014] The heat pipe uses the phase change process of the working medium condensing at the heat releasing end after evaporation at the heat absorbing end (i.e., using the latent heat of evaporation and condensation of the liquid) to conduct heat quickly. Generally, the heat pipe is composed of a tube shell, a liquid wick (medium) and an end cap. The inside of the heat pipe is pumped into a negative pressure state and filled with an appropriate liquid. The boiling point of this liquid can be controlled by the vacuum degree and the selection of the medium to obtain heat pipes with different starting temperatures. When the temperature of the heat absorbing end of the heat pipe is higher than the boiling point of the liquid, the working liquid in the tube core evaporates by heat and takes away the heat. The steam flows from the central channel to the heat releasing end of the heat pipe, condenses into liquid, and releases latent heat at the same time. Under the action of gravity or capillary adsorption, the liquid flows back to the heat absorbing end. In this way, a closed cycle is completed, thereby transferring a large amount of heat from the heat absorbing end to the heat releasing end. When the heat absorbing end is at the bottom and the heat releasing end is at the top, and the heat pipe is placed vertically, the reflux of the working liquid can be satisfied by gravity, and there is no need for a tube core with a capillary structure. This heat pipe without a porous tube core is called a thermosiphon. Heat pipe technology is widely used in aerospace, military and other industries, especially for enhancing heat exchange. Heat pipes can transfer heat quickly and efficiently, and their thermal conductivity can reach dozens or even hundreds of times that of metal copper. Common heat pipe thermal conductivity coefficients range from 10kW / Km to 100kW / Km.

[0015] The present invention regulates the temperature of the temperature-controlled space through a heat pipe, reduces the refrigeration load, and improves the economy of building energy use.

[0016] Preferably, the heat pipe is arranged obliquely, and the two ends of the heat pipe are respectively a heat absorbing end and a heat releasing end, the heat absorbing end faces downward, and the heat releasing end faces upward. There are multiple heat pipes, and the multiple heat pipes are evenly arranged into two rows of heat pipe groups, and the two rows of heat pipe groups are symmetrically arranged along the wall structure.

[0017] Preferably, the heat pipes in one row of the heat pipe group are energy-releasing heat pipes, the heat-releasing ends of the energy-releasing heat pipes are placed in the energy storage material, and the operating temperature of the energy-releasing heat pipes is higher than the operating temperature of the energy storage material;

[0018] The air duct on one side of the wall structure is an energy-releasing air duct, the outlet and the inlet of the energy-releasing air duct are both connected to the temperature-controlled space, the heat-absorbing end of the energy-releasing heat pipe is placed in the energy-releasing air duct, the air in the temperature-controlled space passes through the energy-releasing air duct, and the energy-releasing heat pipe replaces the temperature of the air in the temperature-controlled space into the energy storage material to regulate the temperature of the temperature-controlled space.

[0019] Preferably, the heat pipes in the heat pipe group of another row are energy storage heat pipes, the heat absorbing ends of the energy storage heat pipes are placed in the energy storage material, and the operating temperature of the energy storage heat pipes is lower than the operating temperature of the energy storage material;

[0020] The air duct on the other side of the wall structure is an energy storage air duct, the inlet of the energy storage air duct is connected to the temperature control component, the outlet of the energy storage air duct is connected to the temperature control space, the heat release end of the energy storage heat pipe is placed in the energy storage air duct, the temperature control component stores energy in the energy storage material through the energy storage air duct, and the energy storage material after storage controls the temperature of the temperature control space.

[0021] The energy storage material used in the present invention is called phase change energy storage. Phase change energy storage is a type of thermal energy storage. It uses the heat storage characteristics of phase change materials to store or release the heat therein, so as to achieve a certain regulation and control of the temperature of the environment surrounding the phase change material, thereby changing the temporal and spatial distribution of energy use and improving the efficiency of energy use. Phase change energy storage uses the change in the thermodynamic state (enthalpy) of the material during the conversion process from one physical state to another. For example, ice absorbs a large amount of heat from the surrounding environment during the process of melting into water, and releases a large amount of heat when it solidifies again. In this process of heat absorption / heat release, the material temperature remains unchanged, that is, the conversion process that can bring a large amount of energy in a very small temperature change range is the main feature of phase change energy storage. Water is our most common phase change material. The heat released when water condenses into ice at 0°C is roughly equal to the heat released when water is heated from 0°C to 80 degrees Celsius. This is because the enthalpy change of the material during phase change (334KJ / Kg) is many times higher than the enthalpy change during temperature change (4.19KJ / Kg), which is also an obvious advantage of phase change materials - high energy density and small volume. The present invention can greatly save electricity pressure, improve economy and reduce energy consumption by using energy storage materials to store cold.

[0022] In the present invention, two groups of heat pipes with different working temperatures are placed alternately, wherein the energy-releasing heat pipe is connected to the energy-releasing air duct, and the energy-storing heat pipe is connected to the energy-storing air duct. The energy-storing air duct cools the heat-releasing end of the energy-storing heat pipe by cold air to solidify the energy-storage material, and the energy-releasing air duct heats the heat-absorbing end of the energy-releasing heat pipe by room temperature air to melt the energy-storage material and cool the air in the temperature-controlled space. The phase change temperature of the energy-storage material is 2-6°C lower than the design temperature of the temperature-controlled space. The temperature control component can cool the air in the temperature-controlled space, and can also cool the energy storage material when photovoltaic power or grid power is surplus, and store the cold in the energy storage material. When power is scarce, the temperature control component is turned off, and the temperature-controlled space is cooled by phase change to release cold, thereby reducing energy consumption.

[0023] The present invention also provides a low-carbon environmental control system, which includes a power generation component and the above-mentioned energy storage temperature control system.

[0024] The power generation component includes a spontaneous power source, which is arranged on the sunny side of the temperature control space. The spontaneous power source is connected to the temperature control component to supply power to the temperature control component.

[0025] Preferably, the power generation component also includes a heat insulation baffle, which is arranged on the shady side of the spontaneous power source, and a heat chamber is arranged between the heat insulation baffle and the spontaneous power source, the lower end of the heat chamber is connected to a ventilation chamber, the ventilation chamber is connected to the external environment, and the upper end of the heat chamber is connected to the external environment, the air in the heat chamber is heated and separated from the upper end of the heat chamber, and the cold air at the lower end of the ventilation chamber enters the heat chamber through the ventilation chamber, thereby replacing the air in the heat chamber.

[0026] Preferably, the ventilation cavity is formed by the temperature-controlled space and an outer facade, the upper end of the outer facade is flush with the spontaneous power source, and the length of the outer facade is smaller than the length of the temperature-controlled space.

[0027] Preferably, the self-generated power source is one or a combination of photovoltaic power generation, wind power generation and hydropower generation.

[0028] Preferably, the low-carbon environment control device further comprises a control device;

[0029] The control device is connected to the spontaneous power source and the temperature control component to control the operation of the spontaneous power source and the temperature control component.

[0030] The present invention also provides a low-carbon environmental control method, which is characterized by comprising the following steps:

[0031] When the temperature of the temperature-controlled space is high, after the air in the temperature-controlled space contacts the heat pipe, the heat pipe replaces the temperature of the air with the temperature of the energy storage material, and the replaced air returns to the temperature-controlled space for temperature control.

[0032] Preferably, contacting with the heat pipe comprises the following steps:

[0033] The air in the temperature-controlled space enters the energy-releasing air duct, and the heat-absorbing end of the energy-releasing heat pipe absorbs the heat of the air in the temperature-controlled space. The medium in the energy-releasing heat pipe vaporizes after absorbing the heat, and the vaporized medium enters the heat-releasing end, is cooled by the energy storage material after absorbing the temperature, and then returns to the heat-absorbing end to absorb the heat of the air in the temperature-controlled space, and the cycle is carried out;

[0034] The energy storage air duct cools the energy storage material to ensure that the working temperature of the energy storage material is lower than the working temperature of the energy release heat pipe.

[0035] Preferably, cooling the energy storage material with the energy storage air duct comprises the following steps:

[0036] The temperature control component generates cold air that passes through the energy storage air duct, and the medium at the heat release end of the energy storage heat pipe is liquefied and returns to the heat absorption end of the energy storage heat pipe under the action of gravity to exchange heat with the energy storage material to cool the energy storage material.

[0037] Preferably, the following steps are also included before the cold air generated by the temperature control component passes through the energy storage air duct:

[0038] The spontaneous power source generates electricity, and the spontaneous power source provides power for the operation of the temperature control component. When the spontaneous power source has surplus power, the temperature control component supplies cold air to the energy storage air duct.

[0039] Compared with the prior art, the present invention has at least the following advantages:

[0040] (1) The present invention uses a heat pipe and utilizes the evaporation-condensation process of the medium in the heat pipe to cool the air in the temperature control space, thereby reducing the load of the temperature control component, reducing energy consumption, and achieving low-carbon temperature control.

[0041] (2) The present invention uses energy storage materials and energy-releasing heat pipes and energy storage heat pipes in combination. When electricity is surplus, the energy storage heat pipes store cold energy in the energy storage materials. When electricity is scarce, the temperature control component releases cold energy through the energy-releasing heat pipes to the temperature-controlled space for cooling, thereby reducing air conditioning energy consumption and improving the economy of the building.

[0042] (3) The present invention achieves low-carbon environmental temperature control by coordinating the heat chamber with the ventilation chamber, the temperature control component with the energy-releasing heat pipe and the energy-storing heat pipe, and the temperature control component with the cold air duct. The three cooperate to cool down the temperature-controlled space, reduce carbon emissions during the operation stage of the building, and achieve low-carbon environmental temperature control.

[0057] Example 1

[0058] like Figure 1-6 As shown, the present embodiment provides an energy storage wall, system and method with flexible resource regulation capability of cold, heat and electricity. The present embodiment is mainly designed to address the problems of weak energy storage capability of conventional building air-conditioning equipment, inability to participate in power demand response, and high air-conditioning load caused by traditional building envelope structure design. The present embodiment includes a temperature control component 2, an air duct 4 and a power generation component, wherein the power generation component is arranged on the sunny side of the temperature control space 1, the air duct 4 and the temperature control component 2 are arranged on the shady side of the temperature control space 1, the power generation component performs green power generation, the power generation component supplies power to the temperature control component 2, and the air duct 4 and the temperature control component 2 cooperate to regulate the temperature of the temperature control space 1.

[0059] The temperature-controlled space 1 is a closed space, which may be a building such as a room, or a sealed space such as a container or a carriage. The temperature-controlled component 2 and the air duct 4 are arranged on the outside of the temperature-controlled space 1 to regulate the temperature in the temperature-controlled space 1.

[0060] The energy storage wall includes a wall structure, the air duct 4 and the heat pipe 3, wherein the wall structure is provided with an energy storage material 22, the air duct 4 is provided on both sides of the wall structure, one end of the heat pipe 3 is fixedly provided in the energy storage material 22 in the wall structure, and the other end of the heat pipe 3 is externally placed in the wall structure, specifically, the other end of the heat pipe 3 is provided in the air duct 4. The air duct 4 is in communication with the temperature control space 1, and the temperature of the temperature control space is controlled by the cooperation of the energy storage material 22, the heat pipe 3 and the air duct 4.

[0061] The heat pipe 3 is arranged at an angle, and the two ends of the heat pipe 3 are respectively a heat absorption end 33 and a heat release end 34, the heat absorption end 33 faces downward, and the heat release end 34 faces upward. The air in the temperature-controlled space 1 passes through the air duct 4, and the heat pipe 3 replaces the temperature of the air in the air duct 4 and then transports it back to the temperature-controlled space 1 to regulate the temperature of the temperature-controlled space 1.

[0062] like Figure 4-6As shown, when the heat absorbing end 33 of the heat pipe 3 is heated by the outside, the internal medium evaporates to form steam which automatically rises to the heat releasing end 34, condenses at the heat releasing end 34 to release heat to form droplets, and automatically flows back to the heat absorbing end 33. The medium automatically circulates inside the heat pipe 3 through the evaporation-condensation process, and transfers heat from the heat absorbing end 33 to the heat releasing end 34. On the basis of the existing heat pipe 3, a medium filling-discharging interface is reserved for the heat pipe 3. When the heat pipe 3 needs to work as a heat conductor, the medium is filled to enable the heat pipe 3 to work normally and transfer heat. When the heat pipe 3 does not need to work, the medium in the heat pipe 3 is evacuated, and the heat pipe 3 becomes a poor conductor of heat and cannot transfer heat.

[0063] In order to further strengthen the regulation of the temperature of the temperature-controlled space, in this embodiment, an energy storage frame 21 is provided on the wall structure. The energy storage frame 21 is a square cavity with a length, width and height of 2-8 cm formed by connecting metal plates vertically and horizontally. The energy storage frame 21 contains the energy storage material 22. The energy storage material 22 is a phase change material with a phase change temperature of 16-20°C. Other materials that can change temperature can also be used. The energy storage frame 21 is fixedly connected to the heat pipe 3. Specifically, the energy storage frame 21 is welded to the heat exchange fins of the heat pipe 3, and the heat exchange is increased by the metal plate. The energy storage frame 21 is tightly fitted with the wall (box) in the shade of the temperature-controlled space 1. The energy storage frame 21 can be adsorbed on the wall, or it can be installed on the structural frame used to provide structural strength by adding a steel frame, so that the energy storage frame 21 is used as a load-bearing wall of the temperature-controlled space 1.

[0064] The heat pipes 3 are provided in plurality, and the plurality of heat pipes 3 are evenly arranged into two rows of heat pipe groups, and the two rows of heat pipe groups are symmetrical along the center line of the energy storage frame. The heat pipes 3 in one row of the heat pipe groups are energy-releasing heat pipes 31, and the heat-releasing ends of the energy-releasing heat pipes 31 are placed in the energy storage material 22. The heat-absorbing pipes 3 of the energy-releasing heat pipes 31 are arranged in the air duct 4. The energy-releasing heat pipes 31 absorb the heat of the air in the air duct 4 and discharge it into the energy storage material 22, so as to regulate the temperature of the temperature-controlled space 1.

[0065] The air duct 4 includes an energy-releasing air duct 41, the outlet and the inlet of the energy-releasing air duct 41 are both connected to the temperature-controlled space 1, and the heat-absorbing end of the energy-releasing heat pipe 31 is arranged in the energy-releasing air duct 41. The working temperature of the energy-releasing heat pipe 31 is higher than the working temperature of the energy storage material 22. When the energy-releasing heat pipe 31 is working, the heat-absorbing end of the energy-releasing heat pipe 31 absorbs the temperature of the air in the energy-releasing air duct 41, and the medium at the heat-absorbing end of the energy-releasing heat pipe 31 is heated up and vaporized, and enters the heat-releasing end of the energy-releasing heat pipe 31. Since the working temperature of the energy storage material 22 is lower than that of the energy-releasing heat pipe 31, the vaporized medium is cooled and condensed into liquid, and under the action of gravity, it returns from the heat-releasing end of the energy-releasing heat pipe 31 to the heat-absorbing end, and repeats the movement.

[0066] The energy storage temperature control system includes the energy storage wall and the temperature control component 6 mentioned above. The temperature control component 6 stores energy in the energy storage material 22 in the energy storage wall. The air duct 4 also includes an energy storage air duct 42. The temperature control component 6 can be a single air conditioner, a fan, a central air conditioner, or other items that can cool or heat. The temperature control component 6 is connected to the inlet of the energy storage air duct 42. The outlet of the energy storage air duct 42 is connected to the temperature control space 1. The other row of heat pipe groups on the energy storage rack 21 is an energy storage heat pipe 32. The heat absorbing end of the energy storage heat pipe 32 is arranged in the energy storage material 22. The heat releasing end of the energy storage heat pipe 32 is arranged in the energy storage air duct 42. The working temperature of the energy storage material 22 is higher than the working temperature of the energy storage heat pipe 32. The temperature control component 6 sends the prepared cold air into the energy storage air duct 42. The heat release end of the energy storage heat pipe 32 contacts the cold wind, and the medium at the heat release end of the energy storage heat pipe 32 cools and condenses into liquid. Under the action of gravity, it flows from the heat release end of the energy storage heat pipe 32 to the heat absorption end of the energy storage heat pipe 32. The heat absorption end of the energy storage heat pipe 32 is arranged in the energy storage material 22. Since the working temperature of the energy storage material 22 is higher than that of the energy storage heat pipe 32, the medium at the heat absorption end of the energy storage heat pipe 32 is heated and vaporized, and returns to the heat release end of the energy storage heat pipe 32. The medium in the energy storage heat pipe 32 repeats the movement until the temperature of the energy storage material 22 is reduced to the same as the temperature of the cold wind produced by the temperature control component 6.

[0067] In order to ensure the operation of the energy storage rack 21, the energy storage rack 21 can be cut into any shape for splicing. In each energy storage rack 21, every 0.3m 2 A heat-releasing end of the energy-releasing heat pipe 31 and a heat-absorbing end of the energy-storing heat pipe 32 are embedded in the area.

[0068] The low-carbon environmental control device includes the above-mentioned energy storage temperature control system and a power generation component, and the power generation component supplies power to the energy storage temperature control system.

[0069] The power generation component includes a spontaneous power source 5, and the spontaneous power source 5 can generate green power. The spontaneous power source 5 is arranged on the sun-facing side of the temperature-controlled space 1, and the spontaneous power source 5 is inclined at the top of the temperature-controlled space 1. Specifically, the spontaneous power source 5 is a photovoltaic panel for solar power generation, and the photovoltaic panel is a photovoltaic silicon panel. Of course, in actual operation, a fan can also be selected for wind power generation, hydropower generation, etc. In this embodiment, the spontaneous power source 5 faces the sun at an inclination angle of 20-60 degrees to the horizontal plane. In order to reduce the influence of the heat generated by the spontaneous power source 5 when generating electricity on the temperature of the temperature-controlled space 1, in this embodiment, a heat insulation baffle 52 is provided at the rear end of the spontaneous power source 5. A heat cavity 51 is formed between the heat insulation baffle 52 and the spontaneous power source 5. The heat cavity 51 is a cavity formed between the spontaneous power source 5 and the heat insulation baffle 52, which is closed on both sides and has openings on the top and bottom. The heat cavity 51 is connected to the ventilation cavity 53. The ventilation cavity 53 is a cavity arranged on the sunny side of the temperature control space 1. Specifically, an exterior facade is constructed by dry hanging method at 10-20 cm on the sunny side of the temperature control space 1. The material of the exterior facade can be common building facades such as ceramic tiles and stones. The exterior facade and the bracket of the temperature control space 1 can form a cavity, which is the ventilation cavity 53. A 20-30 cm channel is reserved at the bottom of the exterior facade to facilitate the air in the external environment to enter the ventilation cavity 53. The heat chamber 51 and the ventilation chamber 53 are closed on both sides, the upper port of the heat chamber 51 and the lower port of the ventilation chamber 53 are open, the upper port of the heat chamber 51 is connected with the external environment, and the lower port of the heat chamber 51 is connected with the upper port of the ventilation chamber 53. The heat generated by the spontaneous power source 5 when generating electricity heats the air in the heat chamber 51, and the heated air rises, and the cool air near the ground is sucked in through the ventilation chamber 53, and discharged from the upper port of the heat chamber 51. The solar radiation heat generated by the spontaneous power source 5 can be taken away through the heat chamber 51 and the ventilation chamber 53, thereby reducing the solar radiation heat entering the temperature control space 1 and reducing the refrigeration load.

[0070] The spontaneous power source 5 performs photovoltaic power generation and transmits the generated electricity to the temperature control component 6 for cooling. The temperature control component 6 is provided with two outlets, one of which is connected to the temperature control space 1 through the cold air duct 61, and the other is connected to the energy storage duct 42. A valve is provided on the other outlet of the temperature control component 6. When the electricity generated by the spontaneous power source 5 is sufficient and surplus, the valve opens, and the temperature control component 6 supplies cold air to the energy storage duct 42 from the other outlet.

[0073] In order to further deepen the understanding of the present invention, this embodiment provides the following specific operation steps:

[0074] Taking a building as a temperature-controlled space 1 as an example, the method for low-carbon environmental control includes the following steps:

[0075] (1) Installation:

[0076] First, a self-generating power source 5 is arranged on the top of the house. The self-generating power source 5 is arranged obliquely and fixedly arranged on the top of the house by a supporting rod 54. The self-generating power source 5 is arranged facing the sun. A ventilation cavity 53 is arranged on the side wall of the building. The ventilation cavity 53 is arranged on the sunny side of the house, such as the south facade, west facade, east facade and other building interiors where the sun can be seen. The ventilation cavity 53 is connected with the heat cavity 51;

[0077] The energy storage frame 21 and the energy release air duct 41 and the energy storage air duct 42 are installed on the other side wall of the house, the energy storage material 22 is filled on the energy storage frame 21, and the return air box 8 is installed inside the house. Of course, in order to achieve a better control effect, the return air box 8 is installed at the bottom of the house, the return air box 8 is connected to the energy release air duct 41 and the temperature control component 6, and the temperature control component 6 is connected to the energy storage air duct 42 and the cold air duct 61; the energy release heat The tube 31 and the energy storage heat pipe 32 are installed on the energy storage frame 21, the heat absorbing end of the energy releasing heat pipe 31 is installed in the energy releasing air duct 41, the heat releasing end of the energy releasing heat pipe 31 is installed in the energy storage material 22, the heat absorbing end of the energy storage heat pipe 32 is installed in the energy storage material 22, the heat releasing end of the energy storage heat pipe 32 is installed in the energy storage air duct 42, the energy releasing air duct 41, the energy storage air duct 42 and the cold air duct 61 are connected to the house through the air supply box 7.

[0078] At the same time, the power generation sensor and the automatic start and stop control module of the spontaneous power source 5 are connected to the spontaneous power source 5, the power grid peak and valley information receiver is connected to the power grid, the air temperature sensor is installed in the temperature control space 1, and the energy storage material 22 temperature sensor is installed on the energy storage rack 21. The control device is connected to the spontaneous power source 5 and the temperature control component 6, the power generation sensor, the power grid peak and valley information receiver, the automatic start and stop control module of the spontaneous power source 5, the air temperature sensor, and the energy storage material 22 temperature sensor to control the operation of the entire device.

[0079] Of course, in order to further ensure the refrigeration effect of the device, a thermal insulation layer is also installed on the outside of the refrigeration cabinet.

[0080] (2) Usage:

[0081] The self-generated power source 5 performs photovoltaic power generation, and the control device transmits the power of the self-generated power source 5 to the temperature control component 6 for cooling. At the same time, the return air box 8 starts to transmit the air in the room to the temperature control component 6 and the energy release air duct 41. The refrigeration box generates cold air, which is directly transmitted to the air supply box 7 through the cold air duct 61. The air in the energy release air duct 41 contacts the heat absorption end of the energy release heat pipe 31. The medium at the heat absorption end is heated and evaporates into a gas state, rising to the heat release end of the energy release heat pipe 31. Due to the energy storage The working temperature of the material 22 is lower than that of the energy-releasing heat pipe 31. The medium in the heat-releasing end of the energy-releasing heat pipe 31 is cooled into liquid by the energy storage material 22, and flows back to the heat-releasing end of the energy-releasing heat pipe 31 under the action of gravity. While the medium in the energy-releasing heat pipe 31 circulates, the heat of the air in the energy-releasing air duct 41 is absorbed to reduce the air temperature in the energy-releasing air duct 41. The cooled air will be transported to the air supply box 7, and the air supply box 7 will transport the cold air and the cooled air into the house for temperature control.

[0082] When the control device detects that the power generated by the self-generated power source 5 is sufficient and has surplus, the control device opens the valve provided on another outlet of the temperature control component 6, and the temperature control component 6 is connected to the energy storage air duct 42. The cold air generated by the refrigeration device passes through the heat release end of the energy storage heat pipe 32 to cool the medium at the heat release end of the energy storage heat pipe 32. The liquefied medium flows back from the heat release end of the energy storage heat pipe 32 to the heat absorption end of the energy storage heat pipe 32 under the action of gravity. Since the working temperature of the energy storage material 22 is higher than that of the energy storage heat pipe 32, the medium at the heat absorption end of the energy storage heat pipe 32 absorbs heat and vaporizes and returns to the heat release end of the energy storage heat pipe 32 for circulation, and the energy storage heat pipe 32 reduces the temperature of the energy storage material 22. The temperature of the energy storage material 22 is kept at a relatively low temperature for energy storage.

[0083] When the spontaneous power source 5 is insufficiently charged, the valve of another port of the temperature control component 6 is closed, the energy storage air duct 42 is closed, and the energy release heat pipe 31 starts working to gradually transfer the temperature in the energy storage material 22 to the air in the energy release air duct 41, and cooperates with the temperature control component 6 to regulate the temperature of the room, thereby realizing low-carbon environmental regulation.

[0084] In this embodiment, the startup and shutdown of the spontaneous power source 5 is controlled by the automatic start-stop control module of the spontaneous power source 5, the power generation situation and the power grid electricity price are detected by the power generation sensor and the power grid peak-valley information receiver, the temperature of the temperature-controlled space 1 is detected by the air temperature sensor, and the temperature of the energy storage material 22 is detected by connecting the energy storage material 22 temperature sensor. When the power generation sensor and the power grid peak-valley signal receiver detect that there is surplus electricity, the temperature control component 6 is started. When the indoor temperature is within the design range, the cold air duct 61 and the energy release air duct 41 of the temperature control component 6 are closed, and the valve of the other port of the temperature control component 6 is opened. The temperature control component 6 is connected to the energy storage air duct through the energy storage air duct. The duct 42 and the energy storage heat pipe 32 cool the energy storage material 22 and store the cold. When it is detected that the temperature of the energy storage material 22 is lower than the set value, the cold storage is stopped. When the power generation sensor and the peak and valley signal receiver of the power grid detect that there is a shortage of electricity, the cold air duct 61 and the energy storage duct 42 of the temperature control component 6 are closed, and the energy release duct 41 is opened to cool the indoor air through the energy storage material 22 to play a refrigeration role. When the energy storage material 22 is cooled and it is detected that the temperature of the temperature control space 1 is too high, the temperature control component 6 is opened, the energy storage duct 42 and the energy release duct 41 are closed, and the cold air duct 61 is opened to directly cool the temperature control space 1. During use, the capacity and operation strategy of each module of the system can be optimized according to the local peak power consumption period, duration, photovoltaic power generation peak and other information to give full play to the demand response capability of the device.

[0085] Assume that the temperature of the energy storage rack 21 is 28°C in the initial state, and the energy storage material 22 is in a liquid state at 28°C at this time. When the power generated by the spontaneous power source 5 is sufficient and surplus (or when the power grid electricity price is low), the temperature control component 6 increases the output, blows out cold air below 22°C, and opens the energy storage air duct 42 at the same time. The energy storage heat pipe 32 begins to quickly cool the energy storage material 22, and the energy storage material 22 changes from a liquid state at 28°C to a liquid state at 24°C to a solid state at 24°C to a solid state at 22°C. Since the operating temperature of the energy storage heat pipe 32 can be reduced to 22°C at most, the temperature of the energy storage material 22 can be reduced to 22°C at the lowest.

[0086] However, when the power generated by the self-generated power source 5 is insufficient (or the price of the power grid is high), the temperature control component 6 reduces its output or even shuts down. At this time, the temperature in the house will gradually rise. When the temperature in the house rises to 26°C, the energy-releasing heat pipe 31 starts to work. The medium in the heat-absorbing end of the energy-releasing heat pipe 31 contacts the air in the house and heats up and vaporizes, rising to the heat-releasing end of the energy-releasing heat pipe 31. The energy storage material 22 condenses the medium at the heat-releasing end of the energy-releasing heat pipe 31 and circulates it to the house. The air in the house is cooled, and the temperature in the house is lowered. As the energy storage material 22 absorbs the heat of the house, the temperature begins to rise, from 22°C solid to 24°C solid to 24°C liquid to 26°C liquid. As the working temperature of the energy-releasing heat pipe 31 is 26°C, when the temperature of the energy storage material 22 reaches 26°C, the energy-releasing heat pipe 31 cannot cool the air in the energy-releasing air duct 41, and the energy-releasing heat pipe 31 stops working. The temperature of the energy storage material 22 rises to 26°C at most.

[0087] Then the cycle can be continued to carry out low-carbon environmental regulation of the house.

[0088] The present invention can reduce the air-conditioning load. By adopting the embedded design of the heat pipe 3 and utilizing the excellent unidirectional thermal conductivity of the heat pipe 3, the indoor heat can be quickly discharged, the air-conditioning cooling load can be reduced, and the local photovoltaic, phase change energy storage and other flexible thermal and cold electricity resources can be comprehensively utilized to improve the energy flexibility of the temperature control component 6 and the grid demand response capability. When the grid has surplus power, the temperature control component 6 cools the phase change material on the basis of meeting the indoor cooling load demand and stores the cold in the energy storage material 22. When power is scarce, the local photovoltaic power supply can be used, or the temperature control component 6 can be turned off to release cold through the energy storage material 22 to cool the house. The control module automatically controls the operation of the energy components and the air duct 4 according to the indoor temperature, photovoltaic power, and grid peak and valley information, which can significantly improve the economy of building energy use and reduce carbon emissions during the building operation stage.

[0089] The present invention forms a heat cavity 51 on the back of the self-generated power source 5 and a material with good thermal insulation performance, which not only effectively blocks the direct heat radiation of the sun to the building, but also forms a ventilation effect on the sun-facing side driven by the hot air in the heat cavity 51, thereby reducing the solar radiation heat from entering the interior of the building through the wall and reducing the cooling load of the building.

[0090] The present invention helps to maximize local photovoltaic consumption and reduce the demand for purchased electricity. In the present invention, a self-generated power source 5 is used to drive a temperature control component 6 for cooling. The load peak of the temperature control component 6 is usually synchronized with the peak power generation of the self-generated power source 5, which helps to consume the self-generated power source 5. In addition, the temperature control component 6 can cool the energy storage material 22 when there is surplus electricity and store the cold energy in the energy storage material 22. When there is a lack of electricity, the temperature control component 6 is turned off to release the cold energy through the energy storage material 22 for cooling.

[0091] The present invention uses a temperature control component 6, energy storage material 22 and energy release heat pipe 31, energy storage heat pipe 32, heat chamber 51 and ventilation chamber 53, and the three are used synchronously to perform temperature control, which can greatly improve the economy of building energy use and reduce carbon emissions during the operation stage of the building.

[0092] Example 2

[0093] The specific operation is consistent with that of Example 1, except that the inlet of the energy-releasing air duct is connected to the temperature control component, and the inlet of the energy-storing air duct is connected to the temperature-controlled space. When the temperature of the house is low, the air of the house passes through the energy-storing air duct, and the medium at the heat-releasing end of the energy-storing heat pipe in the energy-storing air duct is cooled and solidified into liquid and flows to the heat-absorbing end of the energy-storing heat pipe. Since the working temperature of the energy-storage heat pipe is lower than the working temperature of the energy-storage material, the energy-storage material re-gasifies the liquid medium at the heat-absorbing end of the energy-storage heat pipe into gas and flows back to the heat-releasing end of the energy-storage heat pipe for circulation, thereby heating the air in the house.

[0094] When the amount of electricity generated by the spontaneous power supply is sufficient and surplus, the temperature control component is connected to the energy-releasing air duct, and the temperature control component produces hot air, which enters the energy-releasing air duct. The medium at the heat-absorbing end of the energy-releasing heat pipe in the energy-releasing air duct is heated and vaporized, and flows to the heat-releasing end of the energy-releasing heat pipe. The working temperature of the energy-releasing heat pipe is higher than the working temperature of the energy storage material. The energy storage material reliquefies the vaporized medium at the heat-releasing end of the energy-releasing heat pipe and refluxes it to the heat-absorbing end of the energy-releasing heat pipe for circulation until the energy storage material is heated and stores energy.

[0095] When electricity is tight or the amount of electricity generated by the self-generated power source is insufficient, the energy storage air duct is opened, and the energy storage material and the energy storage heat pipe are used to heat the air in the house to control the temperature.

[0096] Example 3

[0097] The specific implementation is consistent with Example 1, in which the power generation component in this embodiment adopts photovoltaic power generation, which includes a photovoltaic power generation module, a photovoltaic power generation waste heat ventilation cooling wall module, a phase change cold storage and release module, a heat pipe low temperature difference rapid heat transfer module, a temperature control component and a system operation control module, which can be modularly produced and assembled. This embodiment reduces energy consumption by reducing the heat of the sun in the building, photovoltaic power generation and phase change material cold storage and release, cools the indoor air according to the power grid and photovoltaic power generation, interacts with the power grid in a friendly manner, and reduces energy costs through demand response.

[0098] Among them, the battery unit constitutes a photovoltaic power generation module, the heat cavity and the ventilation cavity constitute a photovoltaic power generation waste heat ventilation cooling wall module, the energy storage material and the energy storage frame constitute a phase change energy storage and cooling module, the energy release heat pipe, energy storage heat pipe, energy storage air duct, and energy release air duct constitute a heat pipe low temperature difference rapid heat transfer module, and the control device constitutes a system operation control module.

[0099] The photovoltaic power generation module adopts photovoltaic panels, which are placed on the roof facing the sun at an inclination angle of 20-60 degrees to the horizontal plane to generate photovoltaic power; the photovoltaic power generation waste heat ventilation cooling wall module forms a rectangular cavity with the back of the photovoltaic panel and materials with good thermal insulation performance. The two sides of the cavity are closed, and the lower bottom and top surfaces of the cavity are open. An external cover panel is installed on the sunny facade of the building, and the wall facade cover panel is connected to the lower edge of the photovoltaic panel. The sunny wall cover panel, the building wall, the photovoltaic panel, and the insulation baffle under the photovoltaic panel are combined to form a connected cavity. The heat generated by the photovoltaic silicon panel heats the air in the cavity at the photovoltaic panel, causing the air to rise due to the heat, and the cool air near the ground is sucked into the cavity and discharged at the upper top surface of the cavity. The solar radiation heat generated by the outer facade of the sunny wall of the building can be taken away through the ventilation cavity, thereby reducing the solar radiation heat entering the building through the wall and reducing the building's cooling load.

[0100] The energy storage frame in the phase-change cold storage and release module is composed of metal plates with a spacing of 3-8 cm connected vertically and horizontally to form a square cavity with a length, width and height of 3-8 cm. The cavity is filled with energy storage materials with a phase change temperature of 16-26°C, which are also called phase change materials. The metal plates and the heat exchange fins of the heat pipe are welded together and the heat exchange is enhanced through the metal grid; the heat pipe low temperature difference rapid heat transfer module contains two groups of heat pipes with different working temperatures, which can cool and heat the phase change material, solidify the phase change material to store cold, or melt the phase change material to release cold. The phase-change cold storage and release module exchanges heat with the outside world through high-efficiency heat transfer heat pipes, and can store and release cold under a small temperature difference. The phase-change cold storage and release module fits tightly with the wall in the shade of the building. It can be attached to the wall, or the energy storage frame can be used as a load-bearing wall of the building by adding a steel frame.

[0101] The plates filled with energy storage materials in the energy storage rack can be cut into any shape and can be collaged.2 The large and small areas are embedded with a heat-releasing end of an energy-releasing heat pipe and a heat-absorbing end of an energy-storing heat pipe. The enhanced heat exchange fins of the two heat pipes are welded together with the metal plate of the energy-storing frame. The heat-absorbing end of the energy-releasing heat pipe is exposed and placed in the energy-releasing air duct during installation to cool the indoor air. The heat exchange of the heat pipe is efficient to melt the phase-change material and release the cold. The heat-releasing end of the energy-storing heat pipe is exposed and placed in the energy-storing air duct during installation. The cold in the temperature control component is transferred by the heat pipe to solidify the phase-change material and store the cold in the phase-change material.

[0102] Air ducts are installed inside and outside the building next to the phase change cold storage and release modules. The energy release duct is installed on the indoor side, and the energy storage duct is installed on the outdoor side. The area of ​​the two air ducts should ensure that the heat absorption end of the energy release heat pipe and the heat release end of the energy storage heat pipe are all placed in the air ducts. The air conditioner stores cold during low electricity consumption and phase change releases cold during peak electricity consumption.

[0103] This embodiment is equipped with a system operation control module, which includes a photovoltaic power generation sensor, a power grid peak and valley information receiver, an automatic start and stop control module of a temperature control component, an air temperature sensor, a phase change material temperature sensor, and an automatic opening and closing valve of an air duct. When the photovoltaic power generation sensor and the information receiver find that there is surplus power, the temperature control component is started. When the indoor temperature is within the design range, the cold air duct and the energy release duct of the temperature control component are closed. The temperature control component cools the phase change material through the energy storage duct to store the cold. When it is detected that the temperature of the phase change material is lower than the set value, the cold storage is stopped; when the photovoltaic power generation sensor and the information receiver find that there is a shortage of power, the cold air duct and the energy storage duct of the temperature control component are closed, and the energy release duct is opened. The indoor air is cooled by the melting of the phase change material to absorb heat, thereby playing a refrigeration role; when the phase change material has finished releasing cold and it is detected that the indoor temperature is too high, the temperature control component is turned on again, the energy storage duct and the energy release duct are closed, and the cold air duct is opened to cool the room through the temperature control component. Users can optimize the capacity and operation strategy of each module of the system according to local peak electricity consumption period, duration, photovoltaic power generation peak and other information, and give full play to the demand response capability of the system.

[0104] The temperature control component can cool the indoor air, or cool the phase change material when there is surplus photovoltaic power or grid power, store the cold in the phase change material, and shut down the refrigerator to release the cold through phase change when there is a lack of power; and the system operation control module and other coolers and control system modules can directly cool the metal plate to radiate cold indoors when heating is needed indoors, or only cool the energy storage material when there is sufficient power or low electricity prices, convert the power into heat and store it. The system operation control module automatically controls the operation of the temperature control component according to the indoor temperature, photovoltaic power, and grid peak and valley information. When the indoor temperature is low and photovoltaic or grid power is abundant, the low-temperature cooling mode is turned on, and the phase change material is solidified through heat exchange between cold air and energy storage heat pipes. When the grid and photovoltaic power are insufficient and the building has cooling needs, the temperature control component can be turned off to release the cold stored in the phase change material to the room through the energy release heat pipe.

[0105] This embodiment includes two groups of heat pipes with specific working temperatures, temperature control components, energy-releasing air ducts, energy-storing air ducts, enhanced heat exchange fins, photovoltaic panels, and control modules, which can be processed and packaged in the factory as a complete assembled module and used as modular building components. The heat pipes, temperature control components, energy-releasing air ducts, energy-storing air ducts, enhanced heat exchange fins, photovoltaic panels, and control modules can also be installed on site according to actual construction. Different heat pipes can be selected according to indoor temperature control requirements.

[0106] The present invention can reduce the load of air conditioning. The present invention adopts a heat pipe embedded wall, and utilizes the excellent unidirectional thermal conductivity of the heat pipe, for example, when it is cool outside in the summer evening, it can quickly reduce the indoor heat discharge and reduce the cold load of the temperature control component. In addition, the back of the photovoltaic panel and the material with good thermal insulation performance form a rectangular cavity, which not only effectively blocks the direct heat radiation of the sun to the building, but also forms a ventilation effect of the sunny exterior wall driven by the residual heat of the photovoltaic back panel. The two sides of the cavity are closed, and the lower bottom surface and the top surface of the cavity are open. The heat generated by the photovoltaic power generation silicon panel heats the air in the cavity, so that the air enters the cavity from the near-ground part of the wall and is discharged on the upper top surface. It is installed on the sunny facade of the building, and the solar radiation heat generated by the facade can be taken away through the ventilation cavity, reducing the solar radiation heat entering the interior of the building through the wall, and reducing the building refrigeration load.

[0107] At the same time, it helps to maximize local photovoltaic consumption and reduce the demand for purchased electricity. In the present invention, photovoltaic power generation is used to drive the temperature control component. The load peak of the temperature control component is usually synchronized with the peak power generation of photovoltaic power, which is helpful for photovoltaic consumption. In addition, the temperature control component can cool the phase change material when there is surplus photovoltaic power, store the cold in the phase change material, and turn off the refrigerator to release the cold through phase change when there is a lack of power to cool the room.

[0108] The present invention comprehensively utilizes local photovoltaic, phase change energy storage and other flexible cold, heat and electricity resources to improve the flexibility of air conditioning energy use and enhance the grid demand response capability. When the grid has surplus power, the temperature control component cools the phase change material on the basis of meeting the indoor cooling load demand and stores the cold in the phase change material. When power is insufficient, it can be powered by local photovoltaic power, or the refrigerator can be turned off to release cold through phase change to cool the room. The system operation control module automatically controls the operation of the air conditioning system and ventilation system according to the indoor temperature, photovoltaic power, and grid peak and valley information.

[0109] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application.
