Description

Technical Field

[0001] The utility model belongs to the technical field of building energy conservation and renewable energy utilization, and specifically relates to an all-weather high-temperature cold water circulation preparation system based on an enclosure structure. Background Art

[0002] The rapid development of material level has led to a rapid increase in energy consumption. Among them, building energy consumption accounts for an important part of the total energy consumption of the whole industry, and air conditioning energy consumption is an important part of building energy consumption that cannot be ignored. Taking measures to reduce its energy consumption has become a problem that needs to be solved.

[0003] In new enclosure structures, radiant cooling of ceilings, floors, and walls can use high-temperature cold water (16-20°C) to lower indoor temperatures and create a comfortable environment. It also has advantages such as quietness and no noticeable drafts. In recent years, it has attracted more and more attention and has been gradually promoted in engineering practice. However, the preparation of cold water in its internal flow channel still consumes a lot of energy.

[0004] Radiative cooling materials can emit their own heat in the form of radiation and pass through the "atmospheric window" that allows infrared long waves with a wavelength of 8-13μm to pass through, thereby using space as a natural cold source to reduce their own temperature, which has the advantages of energy saving and environmental protection. Among them, the sky radiation cooling plate covered with high-performance radiation cooling materials can keep its own temperature lower than the external ambient temperature all day long, and reduce the temperature of the water flow inside the sky radiation cooling plate, thereby preparing high-temperature cold water for radiation cooling of the top plate, floor, wall, etc. without consuming additional electricity. At the same time, in order to further improve the performance of the high-temperature cold water preparation device, reduce the convective heat exchange between the external hot environment such as high-temperature air and the radiation cooling material, and reduce the temperature rise of the cold water produced in the cooling plate, it is necessary to take corresponding measures.

The surface of the radiation cooling plate 101 is covered with a selective long-wave high-emissivity film material for sky long-wave radiation cooling; the material can be made of existing technology, such as a polymethylpentene film in which silica microspheres are randomly embedded. As a high-performance radiation cooling film, the selective long-wave high-emissivity film material can prepare high-temperature cold water all day long.

[0053] A heat-insulating layer 104 is provided at the bottom and around the radiation cooling plate 101 to reduce heat exchange between the radiation cooling plate 101 and the surrounding environment; the heat-insulating layer 104 can be made of heat-insulating materials in the prior art, such as polymer foaming resin.

[0054] A high-transmittance and high-resistance film 103 is provided above the radiation cooling plate 101 and is parallel thereto. The cavity formed between the high-transmittance and high-resistance film 103, the radiation cooling plate 101 and the insulation layer 104 is an air layer 102, which is used to reduce heat exchange with the outside air; the high-transmittance and high-resistance film 103 is preferably flush with the top of the insulation layer 104 surrounding the radiation cooling plate 101. The high-transmittance and high-resistance film 103 has high transmittance to infrared long-wave thermal radiation with a wavelength of 8-13 μm, and can allow infrared long waves emitted by a selective long-wave high-emissivity film to pass through, so as to reduce the heat gain brought by the surrounding environment; at the same time, the high-transmittance and high-resistance film 103 itself has a high thermal resistance value, which can reduce heat convection with the surrounding environment; the high-transmittance and high-resistance film 103 can be made of polyethylene film in the prior art.

[0055] The utility model arranges the radiation cooling plate 101 inside the heat preservation layer 104, the high-transmittance and high-resistance film 103 and the air layer 102, so as to form a closed sky radiation cooling device 1, which can greatly reduce the convective heat exchange between the radiation cooling plate 101 and the surrounding environment, and further enable the radiation cooling plate 101 to prepare high-temperature cold water around the clock.

[0056] Preferably, the bottom of the sky radiation cooling device 1 has an insulating support foot 105, which is arranged below the bottom insulation layer 104 of the radiation cooling plate 101 to reduce heat conduction between the radiation cooling plate 101 and the underlying structure. The insulating support foot 105 can be made of polytetrafluoroethylene rods in the prior art.

[0057] The radiation cooling plate 101 is preferably an integrally formed structure, which can avoid later assembly. Figure 2As shown, in a preferred embodiment, the radiation cooling plate 101 specifically includes a metal shell 1011, a partition 1012, an inlet flow channel 1013, an outlet flow channel 1014, and a parallel cold water flow channel 1015.

The circulating liquid entering from the inlet flow channel 1013 enters the outlet flow channel 1014 through the parallel cold water flow channel 1015, so that the liquid is cooled by the high-performance radiation cooling film of the roof radiation cooling panel 101 during the flow process.

[0058] Furthermore, if Figure 3 and 4 As shown, the indoor radiation ceiling / floor 9 is provided with an indoor radiation ceiling / floor internal pipe 91, and the indoor radiation wall 14 is provided with an indoor radiation wall internal pipe 141. The internal pipes include but are not limited to copper pipes or plastic pipes. For the indoor radiation ceiling, indoor radiation ceiling floor or indoor radiation wall, the internal pipes can be arranged in series or in parallel, and can efficiently exchange heat with the indoor room. The series connection means that the internal pipe is a coil structure, and the liquid enters from the inlet at one end of the internal pipe without diversion, and then flows out from the outlet; the parallel connection means that a plurality of parallel branch pipes are arranged to connect the inlet main pipe and the outlet main pipe, and the liquid flows into different branch pipes in the inlet main pipe, and is collected in the outlet main pipe and then flows out.

[0059] In more detail, in actual application, the rooftop sky radiation cooling device is fixedly installed on the outside of the building roof; the indoor radiation top plate is set on the inside of the indoor ceiling, the indoor radiation floor is set on the inside of the floor; the indoor radiation wall is set on the inside of the wall, which can efficiently exchange heat with the indoor room.

It can be understood that the number of water supply branches and water return branches is determined according to the number of indoor radiation devices (indoor radiation ceiling and / or indoor radiation floor and / or indoor radiation wall), and the number of water supply branches and water return branches is the same as that of indoor radiation devices, so that the heated liquid in the indoor radiation device is transmitted to the radiation cooling plate 101 of the sky radiation cooling device 1 through the corresponding water return branch pipe, and then the cooled liquid is retransmitted to the corresponding connected indoor radiation device through the corresponding water supply branch pipe.

[0064] Exemplarily, in a specific embodiment of the present utility model, the indoor radiation device includes an indoor radiation ceiling / floor 9 and an indoor radiation wall 14. The water supply branch includes a first water supply branch 7 and a second water supply branch 11, and the return branch includes a first return branch 8 and a second return branch 12. The indoor radiation ceiling / floor 9 and the sky radiation cooling device 1 are connected through the first water supply branch 7 and the first return branch 8, wherein one end of the first water supply branch 7 is connected to the internal pipe inlet of the indoor radiation ceiling / floor 9, and the other end is connected to the water supply main 2, and one end of the first return branch 8 is connected to the internal pipe outlet of the indoor radiation ceiling / floor 9, and the other end is connected to the return main 3. The indoor radiation wall 14 and the sky radiation cooling device 1 are connected through the second water supply branch 11 and the second return branch 12, wherein one end of the second water supply branch 11 is connected to the internal pipe inlet of the indoor radiation wall 14, and the other end is connected to the water supply main 2; one end of the second return branch 12 is connected to the internal pipe outlet of the indoor radiation wall 14, and the other end is connected to the return main 3.

[0065] The liquid after absorbing heat in the indoor radiation device is collected into the return water main pipe 3 through the return water branch pipe, and is transmitted to the radiation cooling plate 101 of the sky radiation cooling device 1 for cooling; the cooled liquid flowing out of the radiation cooling plate 101 of the sky radiation cooling device 1 is diverted into the corresponding water supply branch pipe through the water supply main pipe 2, and then enters the corresponding indoor radiation device to absorb heat again.

[0066] Furthermore, valves for realizing the opening and closing of the water supply main pipe, the return water main pipe, the water supply branch pipe and the return water branch pipe are provided on the water supply main pipe 2. For example, in the present embodiment, a water supply main pipe valve 4 is provided on the water supply main pipe 2, and a return water main pipe valve 5 is provided on the return water main pipe 3. Water supply branch pipes are provided with water supply branch pipe valves, wherein the first water supply branch pipe 7 and the second water supply branch pipe 11 are provided with the first water supply branch pipe valve 10 and the first water supply branch pipe valve 13 respectively; the return water branch pipe valve on the return water branch pipe is not shown. At least two of the indoor radiation ceiling, indoor radiation floor and indoor radiation wall of the utility model are arranged in parallel and provided with valves, which can be switched on and off by corresponding valves according to needs.

[0067] A water pump 6 is also provided on the water supply main pipe 2 or the water return main pipe 3 to provide power for water circulation. The circulating water can circulate in the system pipeline under the drive of the water pump.

[0068] It is understandable that the internal flow channel of the sky radiation cooling panel, the internal pipe of the indoor radiation ceiling / floor, the internal pipe of the indoor radiation wall, the water supply main pipe, the return water main pipe, the water supply branch pipe, the return water branch pipe, the valve, and the water pump all have circulating liquid, preferably water, so as to realize the circulation flow and bring the heat absorbed indoors to the rooftop sky radiation cooling device for heat dissipation.

[0069] Based on the above embodiments, the all-weather high-temperature cold water circulation preparation system based on the enclosure structure of the utility model has the following working process:

[0070] The water flow in the internal pipe of the indoor radiation device absorbs the heat inside the enclosure structure through the indoor radiation ceiling / floor 9 and the indoor radiation wall 14; after the water flow absorbs heat and heats up, it is driven by the water pump 6 and flows through the first return water branch pipe 8 and the second return water branch pipe 12 to the indoor radiation ceiling / floor 9 and the indoor radiation wall 14 into the return water main pipe 3, and enters the internal flow channel of the radiation cooling plate 101 of the sky radiation cooling device 1 through the return water main pipe 3, and releases heat and cools down under the action of the radiation cooling plate 101; further, under the action of the water pump 6, the cooled liquid flowing out of the radiation cooling plate 101 is diverted through the water supply main pipe 2 into the corresponding first water supply branch pipe 7 and the second water supply branch pipe 11, and then re-enters the corresponding indoor radiation ceiling / floor 9 and the indoor radiation wall 14 to absorb heat again. By cycling the above process, the heat inside the house can be absorbed by the water flow and discharged to the outside, which has the effect of heat dissipation and cooling inside the house. It can improve indoor comfort and reduce energy consumption.

[0071] The utility model is an all-weather high-temperature cold water circulation preparation system based on the enclosure structure. An indoor radiation ceiling and / or indoor radiation floor and / or indoor radiation wall are arranged on the inner side of the enclosure structure so that the liquid inside absorbs indoor heat. After the liquid absorbs heat and heats up, it is transmitted through the circulation pipeline to the rectangular flow channel inside the sky radiation cooling plate arranged outside the roof to release heat and cool down, and then flows back to the indoor radiation ceiling and / or indoor radiation floor and / or indoor radiation wall internal pipeline to continue absorbing heat. The water pump provides the power for the high-temperature water to flow in the entire circulation pipeline. The sky radiation cooling device uses the sky as a natural cold source to radiate heat, without consuming additional electric energy for cooling, and only the water in the circulating heat exchange pipeline is provided with the circulation flow power by the water pump.
