Description

Technical Field

[0001] This invention belongs to the field of building energy conservation technology, specifically relating to a passive temperature-regulating ventilation system and method coupled with a Transbry wall-heat pipe chimney. Background Technology

[0002] Using renewable energy for passive temperature control and natural ventilation in buildings is not only an effective way to reduce conventional energy consumption in buildings, but also an effective guarantee for promoting the construction of "good houses" and improving the quality of life.

[0003] Currently, common passive temperature control technologies in buildings mainly include: using underground ventilation for pre-cooling or preheating of fresh air, using solar collectors on the sunny side for direct heating, and using solar chimneys to enhance thermal pressure difference to promote natural ventilation. In recent years, heat pipes, due to their extremely high non-powered isothermal heat transfer characteristics, have also been gradually introduced into the heat transfer design of building envelopes. However, in practical engineering applications, these technologies are mostly set up independently or simply physically superimposed, failing to form an efficient system linkage based on the heating characteristics of the building space. This results in the following shortcomings in existing systems when dealing with the complex comfort requirements of winter and summer: (1) In summer, the driving force of passive cooling is insufficient and the utilization rate of cold source is low. Although traditional underground air ducts can provide cooling fresh air in summer, due to the limited temperature difference between indoors and outdoors, it is often difficult to form a continuous and strong natural ventilation force. Although existing solar chimneys can exhaust air, they are usually only used to remove indoor polluted air and fail to effectively link with underground air ducts to form a complete airflow circulation, resulting in limited natural cooling effect; (2) There is a serious problem of uneven spatial heat distribution in solar thermal utilization. Due to the limited angle of solar radiation, existing window collectors or solar chimneys can only be placed on the sunny side, such as the south wall, west wall, or roof. This results in a large amount of collected heat accumulating in the building envelope and near the windows, while the depths of the room or shaded areas remain cold. Due to the lack of effective means to quickly transfer surface heat to the depths of the room without passive heating, local overheating and overall discomfort are very likely to occur. (3) The system lacks flexible seasonal adaptability and airflow organization strategies. Most traditional heat collection or ventilation structures did not fully consider the diametrically opposed thermodynamic requirements of winter and summer in the initial design stage. For example, in summer, it is necessary to isolate heat from the external network and exhaust air to the outside, while in winter, it is necessary to capture heat and circulate it indoors. Existing systems often lack reasonable damper switching and thermal path control mechanisms, resulting in low overall utilization efficiency of the equipment throughout the year. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and address issues such as insufficient natural ventilation drive in summer, uneven distribution of solar heating in winter, and insufficient seasonal adaptability in existing passive temperature-controlled ventilation systems for buildings, this invention provides a passive temperature-controlled ventilation system and method coupled with a Transbryne wall and heat pipe chimney. This invention adjusts the opening and closing states of various air valves, air vents, and windows according to the season, indoor heating and cooling load, ventilation requirements, and extreme weather conditions, enabling the system to switch between summer ventilation and cooling mode, winter circulating heating mode, winter fresh air preheating mode, transitional season ventilation mode, and extreme condition heat storage and exhaust mode.

[0005] This invention is achieved through the following technical solution: A passive temperature-regulating ventilation system coupled with a Transbryne wall and a heat pipe chimney consists of a Transbryne wall and a heat pipe chimney. The south-facing exterior wall of the building is the south wall, on which south-facing windows (transparent but not operable) are installed, with glass panels fixed to the exterior wall. The north-facing exterior wall of the building is the north wall, on which north-facing windows (operable) are installed. The heat pipe chimney is located above the roof and close to the north wall, and it connects to the interior of the building. A heat collection plate is installed on the outer wall of the south wall. The heat collection plate is positioned opposite to the glass plate. A heat collection air channel is set between the heat collection plate and the glass plate. The upper and lower ends of the heat collection air channel are connected to the outdoor space. The south wall, the glass plate, the heat collection plate, and the heat collection air channel constitute the Transb wall. A south wall vent is installed at the top of the south wall, and the interior is connected to the heat collection air channel through the south wall vent. A No. 1 air valve is installed at the location of the south wall vent. A south wall downwind vent is installed at the bottom of the south wall. An underground air duct is installed on the foundation directly below the heat collection air duct. The underground air duct is connected to the indoor space through corresponding air valves and air vents. It is used to introduce air that has undergone underground heat exchange into the room during summer or when fresh air is required. The heat collection air duct, the south wall downwind vent, the underground air duct, and the indoor space are interconnected. Air valve #3 is installed at the south wall downwind vent, and air valve #5 is installed at the upper end of the underground air duct. A No. 2 air valve is installed in the middle of the heat collection air channel and above the horizontal position of the No. 1 air valve. A No. 4 air valve is installed at the bottom of the heat collection air channel and above the horizontal position of the No. 3 air valve. A No. 6 air valve is installed at the location where the heat pipe chimney connects to the interior of the building. Heat pipes are laid on the roof, with the first end of the heat pipes thermally connected to the heat collector plate and the second end passing through the heat pipe chimney. By adjusting the opening and closing states of each air valve and air outlet, different air flow paths can be formed between the underground air duct, the indoor space, the heat collector air duct, and the outdoor space, thereby meeting the needs of ventilation and cooling in summer, heat collection and heating in winter, and ventilation and air exchange during transitional seasons.

[0006] Furthermore, the heat pipes are laid inside the roof building envelope. These heat pipes transfer the solar radiation heat absorbed by the collector panels across space to the building interior or the heat pipe chimney on the north side, thereby improving the heat distribution inside the building and reducing localized overheating or undercooling. The heat pipe chimney connects to the indoor space through corresponding vents, serving as an auxiliary ventilation, heat exchange, or heat storage exhaust channel under different operating conditions.

[0007] Furthermore, the heat pipes are arranged in a parallel, interconnected, or parallel configuration, with the specific arrangement determined based on the building load and structure. To reduce heat loss during heat transfer, the portion of the heat pipes embedded in the building envelope is equipped with an insulation layer.

[0008] Furthermore, a heat storage layer, a dehumidification layer, or a formaldehyde removal layer are provided on the inner wall of the south wall and / or the inner wall of the underground air duct to meet indoor comfort requirements.

[0009] Furthermore, the height of the heat-collecting air channel is higher than the height of the heat pipe chimney. To reduce the impact of wind pressure, the height of the heat pipe chimney should be designed to be lower than the design height of the Transporin wall to ensure the stable operation of the heat pipe chimney. This invention also provides an operation method based on the above system. According to the season, indoor heating and cooling load, ventilation demand, or building heat storage and exhaust demand, the opening and closing states of air valves #1 to #6 and the north-side windows are adjusted, allowing the passive temperature-regulating ventilation system to switch between summer ventilation and cooling mode, summer enhanced ventilation and cooling mode, winter circulating heating mode, winter fresh air preheating mode, winter heat preservation or auxiliary radiant heating mode, transitional season mixed air mode, transitional season through-draft mode, and extreme state heat storage and exhaust mode, as detailed below.

[0010] The passive temperature-controlled ventilation method described above is used, wherein: when using a passive temperature-controlled ventilation system with a Transbryne wall-heat pipe chimney coupling for temperature control ventilation in summer: 1) Conventional ventilation and cooling mode: Open air valves #3, #5 and #6, close air valves #1, #2 and #4 and the north window, so that the outdoor air and the air in the underground air duct enter the indoor space through the vent on the south wall, and the indoor air enters the heat pipe chimney through the vent on the north wall and is then discharged outdoors. In the conventional ventilation and cooling mode during summer, the air in the heat pipe chimney receives heat transferred from the heat pipe and solar radiation, resulting in increased temperature, decreased density, and upward discharge. This creates a relative negative pressure at the bottom of the heat pipe chimney and in the indoor space. Based on this, with the opening of air valves #3, #5, and #6, air from the outside and underground air ducts enters the room through the south wall vent under the influence of the relative negative pressure difference, and finally exits through the heat pipe chimney. The closing of air valves #1, #2, and #4 prevents unintended short-circuit flow of air through the heat collector air duct. Therefore, this mode relies on the thermal pressure suction effect of the heat pipe chimney to organize airflow. 2) Enhanced ventilation and cooling mode: Open air valves #1, #2, #3, #5 and #6, and close air valve #4 and the north-side window to allow air from the outside and underground air ducts to enter the indoor space. Part of the indoor air enters the heat pipe chimney through the vent on the north wall and is then discharged outdoors, while the other part enters the heat collection air duct through the vent on the south wall and is then discharged outdoors. In the summer enhanced ventilation and cooling mode, the heat pipe chimney and the collector air channel simultaneously serve as natural exhaust channels. Air in the heat pipe chimney, heated, flows upward, creating the first exhaust force; air in the collector air channel, heated by the collector plates, flows upward and is exhausted outdoors through air valve #2, creating the second exhaust force. These two exhaust paths together reduce indoor pressure, thereby drawing air from the outside and the underground air channel, which then enters the room through the downwind vent on the south wall. In this mode, air valves #1 and #2 are opened, allowing some indoor air to enter the collector air channel and be exhausted upwards; air valve #6 is opened, allowing another portion of indoor air to be exhausted through the heat pipe chimney; air valve #4 is closed to prevent outdoor air from directly entering the system from the lower part of the collector air channel, thus preventing airflow short-circuiting. Therefore, this mode can enhance natural ventilation by utilizing the thermal pressure effect of the dual chimneys.

[0011] The passive temperature-controlled ventilation method described above is used, wherein: when performing temperature-controlled ventilation in winter using a passive temperature-controlled ventilation system with a Transbryne wall-heat pipe chimney coupling: 1) Circulating heating mode: Open air valves #1, #3 and #4, close air valves #2, #5, #6 and north window 10, so that outdoor air enters the heat collection air channel through the vent on the south wall, is heated by the heat collection plate, and enters the indoor space through the vent on the south wall. After heat exchange, the indoor air re-enters the heat collection air channel with the outdoor air for circulating heating. 2) Fresh air preheating mode: Open air valves #1, #4, #5 and #6, close air valves #2, #3 and the north window, so that outdoor air, underground air duct and air valves #4 and #5 enter the heat collection air duct, is heated by the heat collection plate and enters the indoor space through the air vent on the south wall, while indoor air enters the heat pipe chimney through the air vent on the north wall and is discharged outdoors; In the winter fresh air preheating mode, the soil temperature is higher than the outdoor air temperature. The air is preheated in the soil before entering the underground air duct, and then enters the heat collector air duct through the south wall vent and air valve #5. The heat collector plates absorb solar radiation and heat the air entering the duct. The heated air becomes less dense and flows upwards along the duct, creating a relative negative pressure at the bottom. It then enters the room through the open air valve #1. Simultaneously, indoor air enters the heat pipe chimney through the open air valve #6 and is exhausted outdoors, thus maintaining indoor air quality and continuous fresh air intake. Air valve #2 is closed, preventing the heated air from being directly exhausted outdoors from the top of the duct. Therefore, under conditions where solar radiation creates sufficient thermal pressure in the duct and the duct resistance is rationally designed, this mode can achieve the preset fresh air flow path through natural buoyancy and the chimney effect. 3) Thermal insulation or auxiliary radiant heating mode: Close air valves 1, 2, 3, 4, 5, and 6, as well as the north-facing window. The heat collection air channel forms a closed air insulation layer. The solar radiation heat absorbed by the heat collection panel is transferred to the roof and / or heat pipe chimney through the heat pipe.

[0012] The passive temperature-controlled ventilation method described above is used, wherein: when using a passive temperature-controlled ventilation system with a Transbryne wall-heat pipe chimney coupling for temperature control ventilation during the transition season: 1) Mixed air mode: Open air valve #1, air valve #2, air valve #3, air valve #5 and north window 10, close air valve #4 and air valve #6, so that the air from the outside and the underground air duct enters the indoor space and mixes, then enters the heat collection air duct through the air vent on the south wall and is discharged outdoors. 2) Through-draft mode: Open air valve #1, air valve #2 and north window 10, close air valve #3, air valve #4, air valve #5 and air valve #6, so that outdoor air enters the indoor space through the north window, passes through the indoor space and enters the heat collection air channel through the wind vent on the south wall and is discharged outdoors.

[0013] The passive temperature control and ventilation method described above employs a system where, under extreme heat storage and exhaust mode, the passive temperature control and ventilation system using a Transbryne wall-heat pipe chimney coupling opens valves #1, #2, and #6, while closing valves #3, #4, #5, and the north-facing window. This allows outdoor air to enter the indoor space through the heat pipe chimney and the north wall vent, then pass through the indoor space and exit outdoors via the south wall vent. The "extreme state" described in this invention primarily refers to special operating conditions where the building envelope and / or indoor space accumulate significant heat, resulting in an indoor temperature higher than the outdoor temperature, necessitating changes to the original functions of the heat collection and release sides of the system to rapidly exhaust the stored heat. Examples include: after continuous high temperatures or strong solar radiation in summer, walls, roofs, and indoor spaces still store considerable heat; after a building has been closed for an extended period, the indoor temperature is significantly higher than the outdoor temperature; air conditioning is shut down, malfunctions, or requires a reduction in peak-hour cooling load; and situations involving short-term high-intensity heat gain from personnel, equipment, or solar radiation.

[0014] In summary, during summer operation, the system can open the passage between the underground air duct and the indoor space, and utilize the heat pipe chimney or Transylvanian wall heat-collecting air duct to form an exhaust path, allowing low-temperature air from the underground air duct to enter the room while simultaneously exhausting indoor air outdoors, thus achieving natural ventilation and cooling. During winter operation, the system can allow indoor air to enter the Transylvanian wall heat-collecting air duct, be heated by the collector plates, and then return to the room, forming indoor air circulation and heating; alternatively, it can introduce fresh air from the underground, preheat it through the Transylvanian wall, and then exhaust it through the heat pipe chimney, combining heating and fresh air exchange. During transitional seasons, the system can utilize the north-facing windows, the indoor space, and the heat-collecting air duct to form a natural ventilation path, and utilize the thermal pressure generated by the Transylvanian wall to assist exhaust. In extreme conditions, the system can switch between the heat-collecting and heat-releasing sides, guiding outdoor air through the indoor space and exhausting it through the Transylvanian wall, thereby removing the heat stored in the building envelope and indoor space.

[0015] Compared with the prior art, the beneficial effects of the technical solution of the present invention are: 1. This invention couples the Transbry wall, underground air duct, heat pipe and heat pipe chimney into a system, which is no longer a simple superposition of single passive components, but forms a temperature-regulating ventilation system that can be switched according to working conditions, thus improving the overall utilization efficiency throughout the year. 2. In summer, the present invention can provide cooling fresh air by using underground air channels and form natural exhaust power with the help of Transbry walls or heat pipe chimneys, thereby enhancing indoor air circulation and improving the problem of insufficient natural ventilation driving force of traditional underground air ducts. 3. In winter, the present invention can use the Transbry wall to heat indoor circulating air or underground fresh air, and transfer solar radiation heat to the interior of the building or the north side area through heat pipes, thereby improving the uneven distribution of solar heating in space and improving indoor thermal comfort. 4. This invention, through the combination and switching of multiple air valves, air vents and windows, can adapt to different thermal environment requirements in summer, winter, transitional seasons and extreme conditions, and has strong seasonal adaptability and operational flexibility. 5. This invention mainly relies on solar energy, underground cold sources, thermal pressure ventilation, and heat pipe non-powered heat transfer to achieve building temperature regulation and ventilation, which can reduce the energy consumption of mechanical refrigeration, heating and ventilation, and is suitable for green buildings and low-energy buildings.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example 1

[0019] like Figures 1 to 7 The passive temperature-controlled ventilation system coupled with a Transbryne wall and a heat pipe chimney, as shown, includes a Transbryne wall and a heat pipe chimney 8. The exterior wall facing the sun is the south wall 1, with a south-facing window 4 installed on it, and a glass panel 2 fixedly installed on its exterior wall. The exterior wall facing away from the sun is the north wall 9, with a north-facing window 10 installed on it. The heat pipe chimney 8 is located above the roof 6 and close to the north wall 9, and it connects to the interior of the building. A heat collection plate 11 is installed on the outer wall of the south wall 1. The heat collection plate 11 is arranged opposite to the glass plate 2. A heat collection air channel 3 is set between the heat collection plate 11 and the glass plate 2. The height of the heat collection air channel 3 is higher than the height of the heat pipe chimney 8. The south wall 1, the glass plate 2, the heat collection plate 11 and the heat collection air channel 3 constitute the Trumbo wall. A south wall vent is installed at the top of the south wall 1. The interior is connected to the heat collection air channel 3 through the south wall vent. A No. 1 air valve is installed at the location of the south wall vent. A south wall downwind vent is provided at the bottom of the south wall 1, and an underground air duct 5 is provided on the foundation directly below the heat collection air duct 3. A heat storage layer, a dehumidification layer, or a formaldehyde removal layer is provided on the inner wall of the south wall 1 and / or the inner wall of the underground air duct 5. The heat collection air duct 3, the south wall downwind vent, the underground air duct 5, and the indoor space are interconnected. A No. 3 air valve is provided at the south wall downwind vent, and a No. 5 air valve is provided at the upper end of the underground air duct 5. A No. 2 air valve is installed in the middle of the heat collection air channel 3 and above the horizontal position of the No. 1 air valve. A No. 4 air valve is installed at the bottom of the heat collection air channel 3 and above the horizontal position of the No. 3 air valve. A No. 6 air valve is installed at the location where the heat pipe chimney 8 connects to the interior of the building. A heat pipe 7 is laid on the roof 6 inside the building envelope of the roof 6. The first end of the heat pipe 10 is thermally connected to the heat collection plate 11, and the tail end of the heat pipe 7 passes through the heat pipe chimney 8.

[0020] In this embodiment 1, the heat pipe 7 is arranged in a parallel, interconnected, or parallel configuration, and the portion of the heat pipe 7 embedded in the building envelope of the roof 6 is provided with an insulation layer.

[0021] In this passive temperature-controlled ventilation system, the Transbryne wall end, consisting of the south wall 1, glass plate 2, heat collector plate 11, and heat-collecting air channel 3, serves as the heat-collecting side of the system; the heat pipes 7 arranged in the roof 6 (building top envelope) and inside the heat pipe chimney 8 serve as the heat-dissipating side of the system; and under extreme operating conditions, the functions of the heat-collecting side and the heat-dissipating side may be interchanged. For each air valve and air outlet, this embodiment adopts air valves with freely adjustable angles, ranging from 0 to 90 degrees; the glass plate 2 is made of ordinary transparent glass with a thickness of 4mm, and the heat collector plate 11 is a high-efficiency metal heat-absorbing plate coated with black paint. Example 2

[0022] A method for temperature control ventilation during summer using the passive temperature control ventilation system coupled with a Transbryne wall-heat pipe chimney as described in Example 1: 1) Conventional ventilation and cooling mode (such as...) Figure 8 As shown): When the indoor cooling load is high during the daytime in summer, open air valves #3, #5, and #6, and close air valves #1, #2, #4, and the north-side window 10. This allows outdoor air and air from the underground air duct to enter the indoor space through the vent on the south wall, and indoor air to enter the heat pipe chimney 8 through the vent on the north wall before being discharged outdoors. The main function of this operation mode is to achieve natural ventilation and cooling of the indoor space to meet the thermal comfort requirements of the human body.

[0023] 2) Enhanced ventilation and cooling modes (such as...) Figure 9 As shown): When the indoor cooling load is high during the daytime in summer, open air valves #1, #2, #3, #5, and #6, and close air valve #4 and the north-side window 10. This allows outdoor air and air from the underground air duct to enter the indoor space through air valves #5 and #3. Part of the indoor air enters the heat pipe chimney 8 through the vent on the north wall and is then discharged outdoors, while the other part enters the heat collection air duct 3 through the vent on the south wall and is then discharged outdoors. The main function of this operation mode is to enhance natural ventilation and cooling indoors, meeting the requirements of human thermal comfort. Example 3

[0024] A method for temperature control and ventilation in winter using a passive temperature control and ventilation system with Transbryne wall-heat pipe chimney coupling as described in Example 1: 1) Circulating heating mode (e.g.) Figure 10As shown): When there is a need for indoor heating during the day in winter, open air valves #1, #3, and #4, and close air valves #2, #5, and #6, as well as the north-side window 10. This allows outdoor air to enter the heat-collecting air channel 3 through the vent on the south wall, be heated by the heat-collecting plate 11, and then enter the indoor space through the vent on the south wall. After heat exchange, the indoor air re-enters the heat-collecting air channel 3 with the outdoor air for recirculation and heating. The main function of this operation mode is to rely on the Transbry wall to heat the indoor air, forming a closed-loop heating system to meet the thermal comfort requirements of the human body.

[0025] 2) Fresh air preheating mode (e.g.) Figure 11 As shown): When there is a need for indoor heating and fresh air exchange during the day in winter, open air valves #1, #4, #5, and #6, and close air valves #2, #3, and the north-side window 10. This allows outdoor air and air from the underground air duct to enter the heat collection air duct 3 through air valves #5 and #4. After being heated by the heat collection plate 11, the air enters the indoor space through the vent on the south wall. At the same time, indoor air enters the heat pipe chimney 8 through the vent on the north wall and is then discharged outdoors. The main function of this operation mode is to use the Transbry wall to preheat the underground fresh air and combine it with the exhaust power to discharge indoor air, thereby achieving indoor heating and fresh air exchange and meeting the requirements of human thermal comfort.

[0026] 3) Insulation or auxiliary radiant heating mode (such as...) Figure 12 (As shown): When there is a need for insulation at night in winter, or when the indoor space is heated by heat pipes during the day in winter, the No. 1, No. 2, No. 3, No. 4, No. 5, No. 6 air valves and the north-side window 10 are closed. The heat collection air channel 3 forms a closed air insulation layer, effectively preventing indoor heat from escaping outward. If there is solar radiation during the day, the solar radiation heat absorbed by the heat collection plate 11 is transferred to the roof and / or heat pipe chimney 8 through the heat pipe 7 to radiate heat into the room. The main function of this operation mode is to enhance the thermal insulation performance of the building envelope, or to combine with heat pipes to achieve purely passive indoor auxiliary radiant heating and reduce building heating energy consumption. Example 4

[0027] A method for temperature-controlled ventilation during transitional seasons using a passive temperature-controlled ventilation system coupled with a Transbryne wall and heat pipe chimney as described in Example 1: 1) Mixed air mode (such as...) Figure 13As shown): When there is a need for ventilation and temperature control indoors during the transition season, open air valves #1, #2, #3, and #5, as well as the north-side window 10, and close air valves #4 and #6. This allows outdoor air and air from the underground air duct 5 to mix in the indoor space, then enter the heat-collecting air duct 3 through the vent on the south wall. After being heated by the heat-collecting plate 2, the air flows upward and is discharged outdoors. The main function of this operation mode is to introduce outdoor natural wind and underground wind for mixing and ventilation, and to use the wind-pulling effect generated by the Transbry wall heating the air to assist in the exhaust, so as to achieve a smooth transition and ventilation indoors and meet the requirements of human thermal comfort.

[0028] 2) Through draft mode (such as...) Figure 14 As shown): When there is a need for natural ventilation in the room during the transitional season, open air valves #1 and #2 and the north window 10, and close air valves #3, #4, #5 and #6. This allows outdoor air to enter the indoor space through the north window 10, pass through the indoor space, and then enter the heat-collecting air channel 3 through the vent on the south wall. After being heated in the heat-collecting air channel 3, the air flows upward and is eventually discharged outdoors. The main function of this operation mode is to introduce outdoor natural wind to form a cross breeze, and to use the wind-pulling effect generated by the Transbry wall to assist in the exhaust, thereby achieving efficient natural ventilation in the room and meeting the requirements of human thermal comfort. Example 5

[0029] The method of temperature control and ventilation in extreme heat storage and exhaust mode using a passive temperature control and ventilation system coupled with a Transbryne wall-heat pipe chimney as described in Example 1 (e.g.) Figure 15 As shown): When the building has a need to exhaust internal heat storage under extreme conditions, open air valves #1, #2, and #6, and close air valves #3, #4, and #5, as well as the north-side window 10. At this time, the functions of the heat collection side and the heat release side of the system are switched, allowing outdoor air to flow downwards into the indoor space through the heat pipe chimney 8, which was originally the heat release side, and the vent on the north wall. After passing through the indoor space, it enters the heat collection air channel 3, which was originally the heat collection side, through the vent on the south wall, and finally flows upwards and is exhausted outdoors. The main function of this operation mode is to use the flexible switching of the functions of the heat collection and heat release sides and the wind-pulling effect generated by the Transbry wall to guide the outdoor airflow to deeply traverse the indoor space, efficiently exhaust the heat storage in the building envelope and inside, and reduce the building's cooling load.
