Abstract
Description
Technical Field
[0001] The invention belongs to the field of house structures, and in particular relates to an active heating system and a room. Background Art
[0002] In winter or cold weather, using air conditioning for heating is a common technical means. For rooms in remote locations (such as guardhouses in suburban areas and transfer stations for sanitation workers), the distance is generally 10-15m. 2 The outdoor unit of the air conditioner can only be placed outside the room, which is easy to cause a lot of noise; such rooms need to be scattered everywhere, and secondly, the room is not used for a long time, so it is costly to configure power grid and air conditioner for each booth, and the operating cost of air conditioner is also very high. Although a separate electric heater can be used for heating, the existing electric heater has a high energy consumption ratio and low power, the use effect is not ideal, and the heating is uneven. Summary of the invention
[0003] The purpose of the present invention is to provide an active heating system and room, which can reduce energy consumption and achieve green environmental protection while providing sufficient heat.
[0004] To achieve the above-mentioned purpose, the present invention provides an active heating system, which includes a protective layer, a thermal insulation layer, a first energy storage layer and a second energy storage layer which are nested from the outside to the inside. The middle of the second energy storage layer is a cavity, and the cavity has an air inlet and an exhaust port. The system also includes a solar power generation module, a battery, a controller, an active heating element and an air pump. The controller is connected to the solar power generation module, the battery and the air pump. The active heating element includes a bracket and a plurality of heat absorption tubes arranged on the bracket. The air pump drives air to flow through the active heating element and then enter the cavity.
[0005] As an improvement of the above solution, the upper side of the bracket undulates up and down along its width direction, and the heat absorbing tubes are evenly arranged along the length direction of the bracket, and the air pump drives air to flow into the heat absorbing tubes and then into the cavity. In other solutions, the heat absorbing tubes can be spread out flat, or other methods can be used to increase the area of the heat absorbing tubes receiving radiation.
[0006] As an improvement of the above scheme, a heat collecting tube is installed on the bracket, and the heat collecting tube is provided with branches equal in number to the heat absorbing tubes, and the air in each of the heat absorbing tubes is collected in the heat collecting tube and then pumped into the cavity by the air pump. In other schemes, the air pump can be adjusted to deliver air to the heat absorbing tube, and the output end of the air pump is connected to the air collecting tube, and then the air is delivered to the heat absorbing tube through the air collecting tube, and the output end of each heat absorbing tube is connected to the cavity directly or through another air collecting tube.
[0007] As an improvement of the above solution, the bracket is a galvanized steel plate, the heat absorbing tube is a metal tube, and graphene powder coating is provided on both the inner and outer sides of the heat absorbing tube. In other solutions, the heat absorbing tube can be made of aluminum alloy only, which is also a good thermal conductor.
[0008] As an improvement of the above solution, the protective layer is a steel plate, the thermal insulation layer is thermal insulation cotton, the first energy storage layer is circulating water, and the second energy storage layer is a phase change material, and the phase change materials are mainly inorganic PCM, organic PCM, and composite PCM.
[0009] As an improvement of the above solution, the thickness of the protective layer is 0.2-1 cm, the thickness of the thermal insulation layer is 15-25 cm, the thickness of the first energy storage layer is 15-25 cm, and the thickness of the second energy storage layer is 2-5 cm.
[0010] As an improvement of the above solution, the system also includes a hot air blower, which is installed through the protective layer and the insulation layer, and the output end of the hot air blower is in contact with the outer side of the first energy storage layer, and the hot air blower provides heat to the first energy storage layer.
[0011] To achieve the above object, the present invention also provides a room, comprising the above active heating system.
[0012] As an improvement of the above scheme, the active heating system is installed on the roof of the room. In other schemes, the active heating system can be arranged in parallel with the room, or it can be understood that the sentry box has two rooms separated by an inner door, and then one of them is converted into an active heating system.
[0013] As an improvement to the above solution, cooling films are arranged on the outside of the protective layer and the outside of the room to reflect the sunlight with higher energy. At this time, the heat of the room is mainly provided by the active heating system. This design is used to remove the active heating element in summer and pass low-temperature air into the cavity at night, so as to provide cooling for the room during the day.
[0014] The present invention has the following beneficial effects: the system uses the surrounding energy to preheat the gas when the temperature is high during the day, and then the gas is stored in the cavity. The first energy storage layer and the second energy storage layer are used to continuously absorb heat, which can effectively prevent heat loss. Similarly, the insulation layer isolates the inside and the outside, thereby protecting the first and second energy storage layers; when it is cold at night, the heat is slowly discharged (in this process, the first and second energy storage layers slowly release heat), thereby maintaining the indoor temperature.

DETAILED DESCRIPTION
[0018] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.
[0019] Reference Figure 1 and Figure 2 , the present invention discloses an active heating system and a room. The active heating system includes a protective layer, a thermal insulation layer 13, a first energy storage layer 11 and a second energy storage layer 12 which are nested from the outside to the inside, and the middle of the second energy storage layer 12 is a cavity, and the cavity has an air inlet 31 and an exhaust port 32. In this embodiment, the protective layer is a steel plate, the thermal insulation layer 13 is thermal insulation cotton, the first energy storage layer 11 is circulating water, and the second energy storage layer 12 is a phase change material; the thickness of the protective layer is 0.2-1cm, the thickness of the thermal insulation layer 13 is 15-25cm, the thickness of the first energy storage layer 11 is 15-25cm, and the thickness of the second energy storage layer 12 is 2-5cm.
[0020] Specific as Figure 2 The circulating water has a circulating water inlet 61 and a circulating water outlet 62, between which a water pump is arranged. Generally, the water pump does not need to be operated, and can be restarted when water needs to be replenished or when the water is stirred evenly.
[0021] Specific as Figure 2 As shown, in order to divide the space occupied by the thermal insulation layer 13, the first energy storage layer 11 and the second energy storage layer 12, a steel plate is arranged between the thermal insulation layer 13, the first energy storage layer 11 and the second energy storage layer 12, just like a protective layer. From the outside to the inside, three layers of steel plates can be seen, the outermost layer is called the protective layer; the middle layer and the outermost layer define the thermal insulation layer 13; the middle layer and the innermost layer define the first energy storage layer 11; the surface of the innermost layer is arranged with a phase change material. The thickness of the steel plate can be different for different positions; preferably, steel plates of the same thickness can be selected to facilitate manufacturing and processing.
[0022] In one embodiment, the steel plate is bent into a U-shape, and the bottom, top and one side are all ordinary insulation boards, such as Figure 2As shown. In another embodiment, the steel plate is bent into a ring shape, and the bottom and top are both ordinary heat insulation plates. In this case, the air intake pipe and the exhaust pipe need to pass through the steel plate to reach the internal cavity. In another embodiment, the steel plate is made into a barrel shape (only the opening is open upward), and the barreled steel plates are arranged layer by layer from large to small toward the middle. In this case, in addition to the side, the insulation layer 13, the first energy storage layer 11, and the second energy storage layer 12 are also distributed at the bottom of the system.
[0023] The system also includes a solar power generation module 40, a battery, a controller, an active heating element and an air pump. The controller is connected to the solar power generation module 40, the battery and the air pump. The active heating element includes a bracket 21 and a plurality of heat absorbing tubes 22 arranged on the bracket 21. The air pump drives the air to flow through the active heating element and then enter the cavity. When the temperature is high during the day, the system uses the surrounding energy to preheat the gas, and then the gas is stored in the cavity. The first energy storage layer 11 and the second energy storage layer 12 are used to continuously absorb heat, which can effectively prevent heat loss. Similarly, the insulation layer 13 isolates the inside and the outside to protect the first and second energy storage layers 12; when it is cold at night, it is slowly discharged. In this way, the effect of green energy saving is achieved.
[0024] Specific as Figure 1 As shown, it can be seen that the solar power generation module 40 and the active heating element are arranged side by side on the protective layer. In this embodiment, the room adopts the above-mentioned active heating system, and the active heating system is installed on the roof of the room.
[0025] Preferably, the upper side of the bracket 21 undulates up and down along its width direction, and the heat absorption tubes 22 are evenly arrayed along the length direction of the bracket 21. The air pump drives the air to flow into the heat absorption tube 22 and then enter the cavity. This design can increase the lighting area of the heat absorption tube 22. Figure 2 It can be seen that the lower side of the bracket 21 is a plane that fits the protective layer, and the upper side of the bracket 21 is a continuous inverted V-shaped structure, and the length direction of the V-shaped structure is along Figure 1 In the upper left and lower right direction, the array direction of the V-shaped structure is along Figure 1 The axial direction of the heat absorbing tube 22 is the upper left and lower right direction, and multiple heat absorbing tubes 22 are dispersed in an array along the lower left and upper right direction. The top angle of the V-shaped structure is 40-60°, which can better adapt to the sun's irradiation from different angles and obtain heat to the greatest extent.
[0026] In this embodiment, the bracket 21 is a galvanized steel plate, the heat absorbing tube 22 is a metal tube, and graphene powder coatings are provided on both the inner and outer sides of the heat absorbing tube 22, which can promote the heat absorption of the heat absorbing tube 22. At noon in summer, the temperature of the heat absorbing tube 22 itself is about 50°C; at noon in winter, the temperature of the heat absorbing tube 22 itself is about 40°C; the temperature of the heat absorbing tube 22 is generally 5-15°C higher than the ambient temperature.
[0027] Preferably, a heat collecting tube is installed on the bracket 21, and the heat collecting tube is provided with branches equal in number to the heat absorbing tubes 22. The air in each of the heat absorbing tubes 22 is collected in the heat collecting tube and then pumped into the cavity by an air pump. Figure 1 As shown, the input end of the air pump is connected to the air collecting pipe 23, and then the output end of the air pump is connected to the cavity. In other embodiments, the air pump can be adjusted to deliver air to the heat absorbing tube 22, the output end of the air pump is connected to the air collecting pipe 23, and then the air is delivered to the heat absorbing tube 22 through the air collecting pipe 23, and the output end of each heat absorbing tube 22 is connected to the cavity directly or through another air collecting pipe 23. Figure 1 The transition connection between the heat absorption pipe 22 and the gas collecting pipe 23 is not shown temporarily.
[0028] In order to ensure that the exhaust port 32 can stably output gas, an air pump can be separately set at the location of the exhaust port 32, and multiple branches can be set at the end of the exhaust port 32 to connect to the room. In this embodiment, the air pump uses a low-power pump body, obtains electricity from the solar power generation module 40, and is controlled to start and stop by the controller. In this way, the whole system does not need to be connected to the external power grid, and can achieve green and energy-saving operation.
[0029] Preferably, the active heating system further comprises a hot air blower 50, which is installed through the protective layer and the thermal insulation layer 13, and the output end of the hot air blower 50 is attached to the outer side of the first energy storage layer 11, and the hot air blower 50 provides heat to the first energy storage layer 11. This design is used to supplement a small amount of heat to prevent accidents in which the gas temperature in the cavity is not suitable.
[0030] Preferably, a cooling film is arranged on the outside of the protective layer and the outside of the room to reflect the light with higher energy in the sunlight. At this time, the heat of the room is mainly provided by the active heating system. This design is used to remove the active heating element in the summer and pass lower temperature air into the cavity at night, so as to provide cooling for the room during the day. It should be noted that the cooling film mentioned here belongs to the prior art.
