Abstract

A zero-carbon, heat-insulating mobile house includes a roof, a middle frame, and a base. The middle frame is divided into an outer frame and an inner frame, forming a cavity filled with heat-storing material. A solar vacuum tube collector and a flat water tank (1) are arranged on the roof. The solar vacuum tube collector includes a central manifold and several vacuum tubes mounted on both sides of the manifold. The flat water tank (1) is arranged around the roof and connected to both ends of the manifold. Several superconducting pipes (2) are mounted at the bottom of the flat water tank (1) and extend into the cavity.

Description

Technical Field

[0001] This invention relates to the field of energy-saving building technology, specifically to a zero-carbon insulated mobile house and its insulation method. Background Technology

[0002] As a vital industry closely related to people's daily lives, the construction industry has seen its building forms gradually diversify with the advancement of the times and technology. Mobile homes, as a type of building that is easy to assemble and move, have the advantages of standardization, modularity, and versatility, and are widely used in environmentally friendly public toilets, sanitation facilities, light steel houses, wooden houses, and other outdoor construction projects.

[0003] Currently, mobile homes primarily rely on split-type air conditioners for cooling and heating, which are effective in summer but ineffective in winter. This approach results in significant energy waste and fails to provide efficient and stable control over the indoor temperature. Addressing the issue of mobile homes being exposed to the elements for extended periods on sunny days, the applicant has developed a solar-powered, insulated mobile home. Summary of the Invention

[0004] To address the technical problem in the aforementioned background technology that mobile homes rely solely on air conditioning for winter warmth, resulting in energy waste, this invention provides a zero-carbon, heat-insulating mobile home and a heat-insulating method.

[0005] The technical solution of this invention is as follows:

[0006] A zero-carbon insulated mobile house includes a roof, a middle frame and a base. The middle frame is divided into an outer frame and an inner frame, and a cavity is formed between the outer frame and the inner frame. The cavity is filled with heat storage material.

[0007] The roof is equipped with solar vacuum tube collectors and a flat water tank. The solar vacuum tube collectors consist of a central manifold and several vacuum tubes mounted on both sides of the manifold. The flat water tank is arranged around the entire roof and connected to both ends of the manifold. The solar vacuum tube collectors are laid flat across the entire roof of the mobile house to maximize the utilization of solar energy.

[0008] The bottom of the flat-level water tank is equipped with several superconducting pipes that extend into the cavity. The cavity and superconducting pipes are spaced at corresponding intervals according to the location of the doors and windows of the mobile house.

[0009] The cavity is filled with a phase change heat storage material, which stores heat from the water tank within the cavity via a superconducting pipe. Given the nature of prefabricated houses, heating is needed during the day for workers and at night for rest. Therefore, heat is stored around the perimeter during the day and released at night through radiation. This eliminates the need for air conditioning, achieving warmth in the mobile home and making it energy-efficient and environmentally friendly.

[0010] Furthermore, the zero-carbon insulated mobile home also includes a temperature control system, specifically comprising the following components:

[0011] A first inlet pipe and a first outlet pipe are installed on one side of the flat water tank. A first switch valve is installed on the first inlet pipe and a second switch valve is installed on the first outlet pipe.

[0012] The second water storage tank is connected to the other side of the level water tank via the fifth water outlet pipe and the third water inlet pipe. The fifth water outlet pipe is equipped with a sixth switch valve, and the third water inlet pipe is equipped with a second water replenishment pump.

[0013] The first temperature sensor is installed inside the flat-layer water tank;

[0014] The second temperature sensor and the second liquid level sensor are installed inside the second water storage tank;

[0015] The control unit includes a data acquisition module and a data control module. The data acquisition module is electrically connected to the temperature sensor and the liquid level sensor, and the data control module is electrically connected to each switching valve and the water supply pump.

[0016] By supplying hot and cold water to the level water tank, the water temperature inside can be adjusted to ensure the mobile housing is within a preset temperature range during nighttime use. The hot water supplied from the level water tank to the second storage tank during temperature adjustment can be used for workers' daily washing and bathing. Preferably, the height of the second storage tank is no higher than that of the level water tank, allowing water in the level water tank to flow into the second storage tank solely by gravity.

[0017] Due to the radiation of heat within the mobile home's cavity, and the fact that the flat-bottomed water tank surrounds the top perimeter, resulting in a large contact area with the outside environment, the water temperature cools down quickly at night. To extend the mobile home's nighttime insulation effect, this zero-carbon insulated mobile home also includes a nighttime heating system, specifically comprising the following components:

[0018] The first water storage tank is set higher than the second water storage tank and is connected to the second water storage tank through a third water outlet pipe. A fourth switch valve is installed on the third water outlet pipe.

[0019] A second water outlet pipe and a second water inlet pipe are connected between the first water storage tank and the level water tank. A first water replenishment pump is installed on the second water outlet pipe, and a third switch valve is installed on the second water inlet pipe.

[0020] The first water storage tank is equipped with a first liquid level sensor on its upper part.

[0021] At least the outer wall of the first water storage tank is equipped with insulation material. Since it does not need to be surrounded by the top like the flat water tank, its heat exchange area with the outside air can be minimized. Through the use of the insulation material on the outer wall, the temperature of the water inside is higher than that of the flat water tank at night. Hot water can be supplied to the flat water tank at multiple time intervals to increase the water temperature inside the flat water tank. Through the use of superconducting pipes, radiant heat is continuously supplied to the mobile house.

[0022] Taking into account cloudy or rainy weather, the zero-carbon insulated mobile home also includes a low-temperature water supply system, specifically comprising the following components:

[0023] The heating water tank is connected to the first water storage tank through the fourth water inlet pipe, and the fourth water inlet pipe is equipped with a third water replenishment pump.

[0024] By manually adding hot water to the heating tank, or by the heating tank itself heating cold water, hot water at a suitable temperature can be supplied to the first water storage tank and the flat water tank on cloudy or rainy days, ensuring the warmth of the mobile house at night.

[0025] Considering that cold water is added to the level water tank every day, then heated by the vacuum tube collector, and then successively enters the first and second storage tanks, if the daytime sunlight and temperature are suitable, the cavity inside the mobile home can reach a suitable temperature at night. However, if the sunlight is insufficient, the cavity inside the mobile home will not be able to reach a suitable temperature. To ensure the heating effect of the mobile home as much as possible, this system also includes a waste water reuse system.

[0026] A fourth water outlet pipe is connected to the second water storage tank, which is equipped with a fifth switch valve. In the morning, the water temperature in the second water storage tank is compared with the water temperature in the level water tank. If the water temperature in the second water storage tank is lower, the fifth switch valve is opened to drain the water and make room for hot water. If the water temperature in the second water storage tank is higher, the second water supply pump is activated to supply the remaining water in the second water storage tank to the level water tank. The level water tank then drains an equal amount of water, thereby raising the base water temperature in the level water tank and facilitating the rapid attainment of the preset temperature threshold.

[0027] This application also provides a method for keeping a mobile home warm, which uses the above-mentioned zero-carbon warm mobile home and specifically includes the following steps:

[0028] S1. Obtain the feedback value from the first temperature sensor;

[0029] S2. In real time, compare the feedback value of the first temperature sensor with the first temperature threshold. When the feedback value of the first temperature sensor is greater than the first temperature threshold, open the first switch valve to introduce water into the level water tank. At the same time, open the sixth switch valve to introduce water into the second water storage tank.

[0030] S3. Real-time comparison of the feedback value from the first temperature sensor and the second temperature threshold;

[0031] S31. If the feedback value of the first temperature sensor is less than the second temperature threshold, close the first switching valve and the sixth switching valve.

[0032] S32. If the feedback value of the first temperature sensor is greater than the second temperature threshold, the feedback value of the second liquid level sensor and the second high water level threshold are compared in real time. When the feedback value of the second liquid level sensor is greater than the second high water level threshold, the first switch valve and the sixth switch valve are closed.

[0033] The above method allows for the heating of water during the day using solar vacuum tube collectors, which then transfer the heat to a flat-bottomed water tank. A superconducting pipe at the bottom of the tank stores the heat within a cavity, releasing it at night through radiation. This maintains a suitable temperature inside the mobile home. Furthermore, depending on the weather, heat exchange between external water and the flat-bottomed water tank can ensure a constant water temperature within the tank.

[0034] As another method of heat preservation, two water storage tanks are used: a first water storage tank and a second water storage tank. The first water storage tank stores hot water for heat exchange with the surface water tank, while the second water storage tank is used for workers' daily washing, bathing, and other applications. The specific steps include the following:

[0035] S1. Obtain the feedback value from the first temperature sensor;

[0036] S2. In real time, compare the feedback value of the first temperature sensor with the first temperature threshold. When the feedback value of the first temperature sensor is greater than the first temperature threshold, open the first switch valve to introduce water into the level water tank. At the same time, open the third switch valve to introduce water into the first water storage tank.

[0037] S3. Real-time comparison of the feedback value from the first temperature sensor and the second temperature threshold;

[0038] S31. If the feedback value of the first temperature sensor is less than the second temperature threshold, close the first switching valve and the third switching valve.

[0039] S32. If the feedback value of the first temperature sensor is greater than the second temperature threshold, the feedback value of the first liquid level sensor and the first high water level threshold are compared in real time. If the feedback value of the first liquid level sensor is greater than the first high water level threshold, the fourth switch valve is opened to allow water to enter the second water storage tank.

[0040] S4. Compare the feedback value of the second liquid level sensor and the second high water level threshold in real time. When the feedback value of the second liquid level sensor is greater than the second high water level threshold, close the first switch valve, the third switch valve and the fourth switch valve.

[0041] Furthermore, with the addition of a nighttime heating system, this method also includes the following steps:

[0042] S5. Determine if the current time is within T. 起 and T终 between;

[0043] S6. If the current time is T 起 and T 终 Between these times, the feedback value of the first liquid level sensor is acquired once every preset time T1, and the remaining water volume V1 of the first water storage tank corresponding to the feedback value of the first liquid level sensor is compared with the standard water exchange volume V0.

[0044] S7. If V1 > V0, then jump to S8; if V1 < V0, then return to S6.

[0045] S8. Compare the feedback values ​​from the first temperature sensor and the second temperature sensor;

[0046] S81. If the feedback value of the first temperature sensor is greater than the feedback value of the second temperature sensor, compare the remaining water volume of the second water tank and the second high water level threshold corresponding to the feedback value of the second liquid level sensor to obtain the difference V2 between the two.

[0047] S811. If V2≥V0, open the sixth switch valve to introduce water into the second water storage tank at a flow rate of V0, and then close the sixth switch valve.

[0048] If V0 > V2 > 0, open the sixth switch valve to allow water to enter the second water storage tank at a rate of V2. Then close the sixth switch valve and open the second switch valve to drain water at a rate of V0 - V2.

[0049] If V2 = 0, open the second switch valve to drain water, and the drainage volume is V0.

[0050] S82. If the feedback value of the first temperature sensor is less than or equal to the feedback value of the second temperature sensor, open the second switch valve to drain water, and the drainage volume is V0.

[0051] S9. Start the first water replenishment pump and pump the standard water replacement volume V0 into the level water tank;

[0052] Furthermore, with the addition of a low-temperature water supply system, this method also includes the following steps:

[0053] S10. Determine if the current time is equal to T. 晚 If the current time equals T 晚 Compare the feedback value of the first temperature sensor with the first temperature threshold. If the feedback value of the first temperature sensor is less than the first temperature threshold, turn on the third water pump to fill the first water tank.

[0054] S11. Real-time comparison between the feedback value of the first liquid level sensor and the first high water level threshold. When the feedback value of the first liquid level sensor is equal to the first high water level threshold, start the first water replenishment pump to fill the level water tank with water.

[0055] S12. Open the sixth switch valve to introduce water into the second water storage tank. At the same time, compare the feedback value of the second liquid level sensor and the second high water level threshold in real time. When the feedback value of the second liquid level sensor is equal to the second high water level threshold, close the sixth switch valve and open the second switch valve.

[0056] S13. Compare the feedback value of the first temperature sensor with the first temperature threshold in real time. When the feedback value of the first temperature sensor is equal to the first temperature threshold, shut down the third water supply pump, the first water supply pump, and the second switch valve.

[0057] Furthermore, the addition of a waste water reuse system includes the following steps:

[0058] S14. Determine if the current time is equal to T. 早 If the current time equals T 早 Compare the feedback value of the second temperature sensor with the feedback value of the first temperature sensor. If the feedback value of the second temperature sensor is greater than the feedback value of the first temperature sensor, start the second water supply pump and open the second switch valve at the same time.

[0059] S15. Obtain the feedback value of the second liquid level sensor. When the feedback value of the second liquid level sensor is equal to 0, shut down the second water supply pump and simultaneously close the second switch valve.

[0060] The beneficial effects of this invention are as follows:

[0061] (1) The present invention provides a zero-carbon insulated mobile home that, through structural improvements, stores heat from a water tank within a cavity. Given the nature of prefabricated buildings, workers need heating during the day and at night, so the heat is stored around the perimeter during the day and released through radiation at night. This eliminates the need for air conditioning, achieving warmth in the mobile home and making it energy-efficient and environmentally friendly.

[0062] (2) The zero-carbon insulated mobile house of the present invention is equipped with a constant temperature system, a nighttime heating system, a low-temperature water supply system, and a waste water reuse system. In hot weather, the constant temperature system maintains hot water in the level water tank, the first water storage tank, and the second water storage tank. At the same time, the nighttime heating system exchanges hot water to the level water tank at regular intervals and in a fixed quantity, thereby maintaining the nighttime temperature of the mobile house. In cold weather, the low-temperature water supply system ensures that the heating of the mobile house is not affected. And through the waste water reuse system, the base temperature of the level water tank is increased, so that it can quickly reach the preset value, and then hot water at a suitable temperature is supplied to the first water storage tank and the second water storage tank to meet the needs of the night and the normal needs of the workers.

[0069] See Figure 1 As shown, this application provides a zero-carbon insulated mobile house, which includes an upper roof, a middle frame and a lower base. The middle frame is divided into an outer frame and an inner frame, and a cavity is formed between the outer frame and the inner frame. The cavity is filled with heat storage material.

[0070] A solar vacuum tube collector and a flat water tank 1 are arranged on the roof. The solar vacuum tube collector includes a central manifold and several vacuum tubes mounted on both sides of the manifold. The flat water tank 1 is arranged around the roof and connected to both ends of the manifold. The solar vacuum tube collector is laid flat on the entire roof of the mobile house to maximize the utilization of solar energy.

[0071] The bottom of the flat-level water tank 1 is equipped with several superconducting pipes 2, which extend into the cavity. The cavity and the superconducting pipes 2 are spaced at corresponding intervals according to the location of the doors and windows of the mobile house. Figure 1 The corresponding intervals are not shown; in actual application, they can be set according to the specific location of doors and windows.

[0072] The cavity is filled with a phase change heat storage material, which stores the heat from the water tank within the cavity via a superconducting pipe 2. Given the nature of prefabricated houses, heating is needed during the day for workers and at night for rest. Therefore, heat is stored around the perimeter during the day and released through radiation at night. This eliminates the need for air conditioning, achieving warmth for the mobile home and making it energy-efficient and environmentally friendly. Of course, water or other substances could be used as the heat storage material to save costs, but the effect would be less effective.

[0073] Furthermore, the zero-carbon insulated mobile home also includes a temperature control system, specifically comprising the following components:

[0074] A first inlet pipe 11 and a first outlet pipe 12 are provided on one side of the level water tank 1. The first inlet pipe 11 is equipped with a first switch valve 111, which can allow water to enter the level water tank 1 by gravity or a water pump. The first outlet pipe 12 is equipped with a second switch valve 121, which is used to drain the water in the level water tank 1.

[0075] A second water storage tank 4 is connected to the other side of the level water tank 1 via a fifth outlet pipe 14 and a third inlet pipe 41. The height of the second water storage tank 4 is no higher than that of the level water tank 1. A sixth switch valve 141 is installed on the fifth outlet pipe 14, allowing water in the level water tank 1 to enter the second water storage tank 4 by gravity through the fifth outlet pipe 14. A second water replenishment pump 411 is installed on the third inlet pipe 41, which pumps hot water from the second water storage tank 4 into the level water tank 1.

[0076] A first temperature sensor is installed inside the level water tank 1. The level water tank 1 is arranged around the top, with a first water inlet pipe 11 and a first water outlet pipe 12 on one side along its length, and a second water storage tank 4 on the other side. The first temperature sensor is located in the middle of the width direction of the level water tank 1 to reduce the influence of water inlet and outlet, and can detect the average temperature of the water in the level water tank 1.

[0077] The second temperature sensor and the second liquid level sensor are installed inside the second water storage tank 4.

[0078] The control unit includes a data acquisition module and a data control module. The data acquisition module is electrically connected to the temperature sensor and the liquid level sensor, and the data control module is electrically connected to each switching valve and the water supply pump.

[0079] The control unit also includes an operation panel and a display screen. The display screen is used to show the values ​​fed back by each temperature sensor and liquid level sensor, and the operation panel can be used to manually control the opening and closing of each switching valve and water supply pump.

[0080] By supplying hot and cold water to the level water tank 1, the water temperature inside the tank can be adjusted to ensure that the mobile house is within a preset temperature range when used at night. The hot water supplied from the level water tank 1 to the second storage tank 4 during temperature adjustment can be used for workers' daily washing, bathing, etc.

[0081] Regarding the aforementioned zero-carbon insulated mobile home, this application also provides a method for insulating the mobile home, which can use a control unit to adjust the temperature of the flat-floor water tank 1 to achieve a constant temperature effect in the mobile home, specifically including the following steps:

[0082] S1. Obtain the feedback value from the first temperature sensor.

[0083] S2. Real-time comparison of the feedback value of the first temperature sensor and the first temperature threshold. The first temperature threshold is the upper limit of the water temperature that needs to be reached in the flat water tank. When the feedback value of the first temperature sensor is greater than the first temperature threshold, the first switch valve 111 is opened to introduce water into the flat water tank 1. At the same time, the sixth switch valve 141 is opened to introduce water into the second water storage tank 4.

[0084] S3. Real-time comparison of the feedback value of the first temperature sensor and the second temperature threshold. The second temperature threshold is the lower limit value that the water temperature in the flat water tank needs to reach. When the water temperature is maintained between the upper and lower limits, the heating effect of the mobile house can be guaranteed when it is used at night.

[0085] S31. If the feedback value of the first temperature sensor is less than the second temperature threshold, close the first switch valve 111 and the sixth switch valve 141. At this time, the water temperature in the flat water tank is too low and needs to continue heating until it reaches the upper limit value.

[0086] S32. If the feedback value of the first temperature sensor is greater than the second temperature threshold, the feedback value of the second liquid level sensor and the second high water level threshold are compared in real time. When the feedback value of the second liquid level sensor is greater than the second high water level threshold, the first switch valve 111 and the sixth switch valve 141 are closed.

[0087] Once the second water tank 4 is full, adding water to it can be stopped. The second water tank 4 will be continuously depleted throughout the day due to worker use; as its water level drops, the leveling water tank 1 will replenish it.

[0088] The above methods can maintain a suitable temperature inside the mobile housing. The second water storage tank 4 can not only meet the daily needs of the workers, but also, in bad weather, the hot water in the second water storage tank 4 can be pumped into the level water tank 1 through the second water replenishment pump to achieve a constant water temperature in the level water tank 1.

[0089] As another implementation method

[0090] Considering the heat radiation from the cavity of the mobile house at night, and the fact that the flat-bottomed water tank 1 is surrounded by the roof and has a large contact area with the outside, resulting in rapid water temperature drop at night, this zero-carbon insulated mobile house also includes a nighttime heating system to extend the nighttime insulation effect. Specifically, it includes the following components:

[0091] The first water tank 3 has its top height level with the flat water tank 1 and its bottom height higher than the second water tank 4. It is connected to the second water tank 4 through a third water outlet pipe 32. The connection point is located at the bottom of the first water tank 3. A fourth switch valve 321 is provided on the third water outlet pipe 32, which can allow water in the first water tank 3 to flow into the second water tank 4.

[0092] A second water outlet pipe 13 and a second water inlet pipe 31 are connected between the first water storage tank 3 and the level water tank 1. The second water outlet pipe 13 is equipped with a first water replenishment pump 311, which is used to pump water from the first water storage tank 3 into the level water tank 1. The second water inlet pipe 31 is equipped with a third switch valve 131, which allows water from the level water tank 1 to flow into the first water storage tank 3.

[0093] The first water storage tank 3 is equipped with a first liquid level sensor on its upper part.

[0094] The outer walls of the first water tank 3 and the second water tank 4 are insulated. Since they do not need to be surrounded by a top edge like the flat-bottom water tank 1, they can be made into a rectangular shape to minimize their heat exchange area with the outside air. By setting up the first water tank 3 and the second water tank 4, and using insulated materials on the outer walls of the two tanks, the temperature of the water inside them is higher than that of the flat-bottom water tank 1 at night. The second water tank 4 is used for the daily needs of the workers. The first water tank 3 can be set to supply hot water to the flat-bottom water tank 1 at multiple time intervals at night to raise the water temperature inside the flat-bottom water tank 1. Through the use of the superconducting pipe 2, radiant heat is continuously supplied to the mobile house.

[0095] The specific steps of this implementation method are as follows:

[0096] S1. Obtain the feedback value from the first temperature sensor;

[0097] S2. Real-time comparison between the feedback value of the first temperature sensor and the first temperature threshold. When the feedback value of the first temperature sensor is greater than the first temperature threshold, the first switch valve 111 is opened to allow water to enter the level water tank 1. At the same time, the third switch valve 131 is opened to allow water to enter the first water storage tank 3.

[0098] The nighttime heating system mainly relies on the first water storage tank 3. Therefore, after the water temperature in the level water tank 1 reaches the first temperature threshold during the day, water is preferentially introduced into the first water storage tank 3.

[0099] S3. Real-time comparison of the feedback value from the first temperature sensor and the second temperature threshold;

[0100] S31. If the feedback value of the first temperature sensor is less than the second temperature threshold, close the first switching valve 111 and the third switching valve 131.

[0101] S32. If the feedback value of the first temperature sensor is greater than the second temperature threshold, the feedback value of the first liquid level sensor and the first high water level threshold are compared in real time. If the feedback value of the first liquid level sensor is greater than the first high water level threshold, the fourth switch valve 321 is opened to allow water to enter the second water storage tank 4.

[0102] If the temperature remains high during the day, water will begin to be pumped into the second water tank 4 after the first water tank 3 is full.

[0103] S4. In real time, compare the feedback value of the second liquid level sensor with the second high water level threshold. When the feedback value of the second liquid level sensor is greater than the second high water level threshold, close the first switch valve 111, the third switch valve 131 and the fourth switch valve 321.

[0104] To ensure the normal operation of this heating system, the first temperature threshold should not be too high; it only needs to maintain a suitable temperature for nighttime rest. If the first water tank 3 and the second water tank 4 are frequently found to be empty, the first temperature threshold can be adjusted on the control panel of the control unit.

[0105] The above-mentioned heat preservation method is an automatically executed procedure by the system. In addition, a manual mode is also provided, which can directly control the opening of the fourth switch valve 321 and the sixth switch valve 141 to send water from the first water storage tank 3 or the level water tank 1 into the second water storage tank 4 for direct use by workers.

[0106] S5. Determine if the current time is within T. 起 and T 终 between;

[0107] S6. If the current time is T 起 and T 终 Between these times, the feedback value of the first liquid level sensor is acquired once every preset time T1, and the remaining water volume V1 of the first water storage tank corresponding to the feedback value of the first liquid level sensor is compared with the standard water exchange volume V0.

[0108] The system has a built-in time module, T 起 This refers to the time when the temperature is adjusted at night, between 10 and 12 o'clock. It can be set manually or preset in the system.

[0109] T 终 This refers to the time when the temperature adjustment ends at night, between 5 PM and 7 PM. It can be set manually or preset in the system.

[0110] T1 can be set between 0.5 hours and 2 hours;

[0111] V0 is calculated based on the capacity of the first water tank 3 and the number of heat exchange cycles. After the last heat exchange, the water level in the first water tank 3 is 0.

[0112] S7. If V1 > V0, then jump to S8; if V1 < V0, then return to S6.

[0113] If V1 < V0, it means that the water volume in the first water tank 3 is too low. At this time, return to S6. After the workers add water to the first water tank 3, the system will detect that the water volume has reached the minimum water replacement amount before replacing the water.

[0114] S8. Compare the feedback values ​​from the first temperature sensor and the second temperature sensor;

[0115] S81. If the feedback value of the first temperature sensor is greater than the feedback value of the second temperature sensor, compare the remaining water volume of the second water tank and the second high water level threshold corresponding to the feedback value of the second liquid level sensor to obtain the difference V2 between the two.

[0116] S811. If V2≥V0, open the sixth switch valve 141 to introduce water into the second water storage tank 4, with an inlet volume of V0, and then close the sixth switch valve 141.

[0117] If V0 > V2 > 0, open the sixth switch valve 141 to introduce water into the second water storage tank 4, with an inlet volume of V2. Then close the sixth switch valve 141 and open the second switch valve 121 to drain water, with a drainage volume of V0 - V2.

[0118] If V2 = 0, the second switch valve 121 is opened to drain water, and the drainage volume is V0.

[0119] When the water level in the first water tank 3 is sufficient for water exchange, the water with a standard exchange value of V0 in the leveling water tank 1 must be drained first. Since the second water tank 4 is constantly being used by workers, and the water in the leveling water tank 1 is hot water, the hot water in the leveling water tank 1 should be transferred to the second water tank 4 first for workers' use.

[0120] S82. If the feedback value of the first temperature sensor is less than or equal to the feedback value of the second temperature sensor, open the second switch valve 121 to drain water, and the drainage volume is V0.

[0121] If the water temperature in the level water tank 1 is not as high as the water temperature in the second water tank 4, then it is not necessary to change the water in either tank.

[0122] S9. Start the first water replenishment pump 311 and pump the standard water replacement volume V0 into the level water tank 1;

[0123] As another implementation method

[0124] The zero-carbon insulated mobile home also includes a low-temperature water supply system to cope with cloudy or rainy days, specifically including the following components:

[0125] The heating water tank 5 is connected to the first water storage tank 3 through the fourth water inlet pipe 51, and the fourth water inlet pipe 51 is equipped with a third water replenishment pump 511.

[0126] By manually adding hot water to the heating water tank 5, or by heating cold water itself, hot water at a suitable temperature can be supplied to the first water storage tank 3 and the flat water tank 1 on cloudy or rainy days, ensuring the warmth of the mobile house at night.

[0127] With the addition of a low-temperature water supply system, this insulation method further includes the following steps in addition to the above-described implementation method:

[0128] S10. Determine if the current time is equal to T. 晚 If the current time equals T 晚 Compare the feedback value of the first temperature sensor with the first temperature threshold. If the feedback value of the first temperature sensor is less than the first temperature threshold, turn on the third water pump 511 to fill the first water tank 3 with water.

[0129] T 晚 This refers to the time between 4 PM and 5 PM. It can be set manually or preset in the system. At this time, there is insufficient sunlight, and the water temperature in the flat water tank 1 does not rise significantly. If the feedback value from the first temperature sensor has not yet reached the first temperature threshold, hot water can be injected for heat exchange.

[0130] The method of injecting hot water is either to manually boil water and inject it into the heating tank, or to manually inject cold water into the heating tank 5 and then heat it to the specified temperature. There is no restriction here. However, this step requires that hot water be prepared in the heating tank 5 beforehand and that the water reaches the preset temperature T. 晚 After a certain time, the system will automatically fill the first water tank 3 with water.

[0131] Furthermore, due to the bad weather, the water temperature in the level water tank 1 did not reach the first temperature threshold, and therefore no water was supplied to the first water storage tank 3. Therefore, the amount of water supplied from the heating water tank 5 to the first water storage tank 3 is greater than the capacity of the first water storage tank 3.

[0132] S11. Real-time comparison between the feedback value of the first liquid level sensor and the first high water level threshold. When the feedback value of the first liquid level sensor is equal to the first high water level threshold, start the first water replenishment pump 311 to fill the level water tank 1 with water.

[0133] Here, the first water tank 3 should be filled with water first to ensure continuous warmth at night.

[0134] S12. Open the sixth switch valve 141 to introduce water into the second water storage tank 4. At the same time, compare the feedback value of the second liquid level sensor and the second high water level threshold in real time. When the feedback value of the second liquid level sensor is equal to the second high water level threshold, close the sixth switch valve 141 and open the second switch valve 121.

[0135] Since the first water tank 3 has not supplied water to the second water tank 4 during the day, and given the normal consumption of the second water tank 4, when the first water tank 3 exchanges heat with the level water tank 1, the hot water in the level water tank 1 is preferentially sent to the second water tank 4 for normal use by the workers.

[0136] S13. In real time, compare the feedback value of the first temperature sensor with the first temperature threshold. When the feedback value of the first temperature sensor is equal to the first temperature threshold, shut down the third water supply pump 511, the first water supply pump 311, and the second switch valve 121.

[0137] As another implementation method

[0138] Considering that cold water is added to the level water tank 1 every day, then heated by the vacuum tube collector, and subsequently flows into the first storage tank 3 and the second storage tank 4, if the daytime sunlight and temperature are suitable, the cavity inside the mobile home can reach a suitable temperature at night. However, if sunlight is insufficient, the cavity inside the mobile home will not reach a suitable temperature. To maximize the heating effect of the mobile home, this system also includes a waste water reuse system. Specifically:

[0139] A fourth water outlet pipe 42 is connected to the second water storage tank 4, and a fifth switch valve 421 is installed on it. In the morning, the water temperature in the second water storage tank 4 is compared with the water temperature in the level water tank 1. If the water temperature in the second water storage tank 4 is lower, the fifth switch valve 421 is opened to drain the water and make room for hot water. If the water temperature in the second water storage tank 4 is higher, the second water replenishment pump 411 is started to supply the remaining water in the second water storage tank 4 to the level water tank 1. The level water tank 1 then drains an equal amount of water, thereby raising the base water temperature in the level water tank 1 and facilitating the rapid attainment of the preset temperature threshold.

[0140] With the addition of a waste water reuse system, this insulation method further includes the following steps in addition to the above-described implementation method:

[0141] S14. Determine if the current time is equal to T. 早 If the current time equals T 早 Compare the feedback value of the second temperature sensor with the feedback value of the first temperature sensor. If the feedback value of the second temperature sensor is greater than the feedback value of the first temperature sensor, start the second water supply pump 411 and open the second switch valve 121 at the same time.

[0142] T 早 This refers to the time between 8 and 9 a.m., which can be set manually or preset in the system. At this time, the workers have already started work, and the second water tank 4 is no longer in use. The water in the second water tank 4 can be reused, while freeing up space to receive hot water.

[0143] S15. Obtain the feedback value of the second liquid level sensor. When the feedback value of the second liquid level sensor is equal to 0, shut down the second water supply pump 411 and simultaneously shut down the second switch valve 121.

[0144] This invention relates to a zero-carbon, insulated mobile home. Through structural improvements, heat from a water tank is stored within a cavity. Given the nature of prefabricated buildings, heating is needed during the day for workers and at night for rest. Therefore, heat is stored in the surrounding area during the day and released through radiation at night. This eliminates the need for air conditioning, achieving warmth in the mobile home and making it energy-efficient and environmentally friendly.

[0145] This invention relates to a zero-carbon, insulated mobile home equipped with a constant temperature system, a nighttime heating system, a low-temperature water supply system, and a waste water reuse system. In hot weather, the constant temperature system maintains hot water in the ground floor water tank, the first storage tank, and the second storage tank. The nighttime heating system periodically and quantitatively exchanges hot water into the ground floor water tank, thus maintaining the mobile home's nighttime temperature. In cold weather, the low-temperature water supply system ensures uninterrupted heating. Furthermore, the waste water reuse system raises the base temperature of the ground floor water tank, allowing it to quickly reach a preset value before supplying hot water at the appropriate temperature to the first and second storage tanks, meeting the needs of both the nighttime heating and the workers' daily needs.
