Description

Technical Field

[0001] The present invention relates to the technical field of building environment control, and in particular to a solar energy compression temperature control system composite micro-building structure and an operation method thereof. Background Art

[0002] In the field of green buildings, measures to improve the thermal environment by using natural energy for heating, air conditioning, ventilation, etc. have been widely studied. Generally, the indoor temperature of buildings can be regulated by solar energy, geothermal energy, wind energy, bioenergy, etc., so as to partially or completely replace conventional energy and realize low-energy or even zero-energy buildings. However, such energy-saving buildings often require separate systems or equipment, with complex structures, high construction costs, and far less convenience when used than directly using electricity. If the temperature control system can be integrated into the building design system and the cooling or heating cycle can be realized inside the building structure, the cost can be greatly saved on the basis of improving the indoor thermal environment. On the other hand, for the energy supply of the refrigeration system, solar energy can generally be used as a supplementary energy source for heating the refrigerant solution in the absorption refrigeration process. There is a rare precedent for applying solar energy to compression refrigeration. If compression refrigeration can be adopted, the absorber and generator can be omitted, thereby reducing the volume of the refrigeration system and greatly reducing the construction cost of the system.

[0012] Furthermore, the upper surface of the reflective plate is made of polished aluminum material.

[0013] The operating method of the composite micro-building structure of a solar compression temperature control system of the present invention includes summer working conditions and winter working conditions; The operation method in summer is: (1) Open the first air compression valve, close the second air compression valve, open the left condensation valve, close the left bypass valve, open the right bypass valve, and close the right condensation valve; (2) The reflector collects solar energy and reflects it to the heat absorbing plate under the heat collecting main pipe. After absorbing the heat, the heat absorbing plate transfers the heat to the bimetallic sheet in close contact with it, and then transfers the heat to the heat collecting main pipe in close contact with the bimetallic sheet, thereby increasing the air temperature in the heat collecting main pipe. (3) The air that has expanded due to heat enters the left air compression pipe and the left hollow tube column through the first air compression valve, and pushes the first refrigerant compression piston downward, so that the refrigerant at the bottom of the left hollow tube column is compressed and enters the left condensing coil through the left condensing valve. The refrigerant in the condensing coil releases heat through water cooling or air cooling. After the refrigerant is liquefied, it is decompressed through the first expansion valve and then enters the evaporating coil to absorb the indoor heat of the building, thereby reducing the indoor air temperature; (4) After the refrigerant is vaporized in the evaporator coil, it enters the right bypass pipe and the right hollow pipe column, pushing the second refrigerant compression piston upward; (5) At the same time, the bimetallic strip continues to absorb heat from solar radiation and gradually deforms. Since the two outer sides of the bimetallic strip are fixedly connected to the outer surface of the heat collecting main pipe, only the middle part can expand and deform. After the middle part of the bimetallic strip expands and deforms, it bulges downward, so that it is no longer in close contact with the heat collecting main pipe, the heat transfer with the heat collecting main pipe decreases, and the air temperature in the heat collecting main pipe decreases. (6) Open the second air compression valve and close the first air compression valve. Close the left condensation valve and open the left bypass valve. Close the right bypass valve and open the right condensation valve; (7) As the second refrigerant compression piston moves upward, the air in the right air compression pipe is compressed back to the heat collection main pipe; (8) Since the bimetallic strip is no longer in close contact with the heat absorbing plate after expansion and deformation, the solar radiation heat absorbed by the heat absorbing plate is difficult to transfer to the bimetallic strip. The bimetallic strip gradually cools down, and its middle part shrinks and resets, and it is in close contact with the heat collecting main pipe again. The amount of heat transferred to the heat collecting main pipe increases, and the air temperature in the heat collecting main pipe rises. (9) The heated and expanded air enters the right air compression pipe and the right hollow tube column through the second air compression valve, and pushes the second refrigerant compression piston downward, so that the refrigerant at the bottom of the right hollow tube column is compressed and enters the right condensing coil through the right condensing valve. The refrigerant in the condensing coil releases heat through water cooling or air cooling. After the refrigerant is liquefied, it is decompressed through the second expansion valve and then enters the evaporating coil to absorb the indoor heat of the building, reducing the indoor air temperature; (10) After the refrigerant is vaporized in the evaporator coil, it enters the left bypass pipe and the left hollow tube column, pushing the first refrigerant compression piston upward; (11) At the same time, the bimetallic strip continues to absorb heat from solar radiation, and the middle part expands and deforms, then bulges downward, and is no longer in close contact with the heat collecting main pipe. The heat transfer with the heat collecting main pipe decreases, and the air temperature in the heat collecting main pipe decreases. (12) Open the first air compression valve and close the second air compression valve. Open the left condensation valve and close the left bypass valve. Open the right bypass valve and close the right condensation valve. The entire system operation state is completely restored to the initial state. Subsequently, the above working process is cycled to achieve a continuous refrigeration process.

[0014] The operation method in winter is: (1) Open the first air compression valve and close the second air compression valve. Close the left and right condensation valves. Open the left and right bypass valves; (2) The reflective plate collects solar energy and reflects it to the heat absorbing plate under the heat collecting main pipe. After absorbing the heat, the heat absorbing plate transfers the heat to the bimetallic sheet that is in close contact with it, and then transfers the heat to the heat collecting main pipe that is in close contact with the bimetallic sheet, so that the air temperature in the heat collecting main pipe increases; (3) The air that has expanded due to heat enters the left air compression pipe and the left hollow tube column through the first air compression valve, and pushes the first refrigerant compression piston downward, so that the refrigerant at the bottom of the left hollow tube column is compressed and enters the left bypass pipe through the left bypass valve, and then enters the evaporator coil, releasing heat into the building room, causing the indoor air temperature to rise; (4) The refrigerant enters the right bypass pipe and the right hollow tube column from the evaporator coil, pushing the second refrigerant compression piston upward; (5) At the same time, the bimetallic strip continues to absorb heat from solar radiation and gradually deforms. Since the outer sides of the bimetallic strip are fixedly connected to the outer surface of the heat collecting main pipe, only the middle part can expand and deform. After the middle part of the bimetallic strip expands and deforms, it bulges downward, so that it is no longer tightly attached to the heat collecting main pipe, the heat transfer with the heat collecting main pipe decreases, and the air temperature in the heat collecting main pipe decreases; (6) Open the second air compression valve and close the first air compression valve; (7) As the second refrigerant compression piston moves upward, the air in the right air compression pipe is compressed back to the heat collection main pipe; (8) Since the bimetallic strip is no longer in close contact with the heat absorbing plate after expansion and deformation, the solar radiation heat absorbed by the heat absorbing plate is difficult to transfer to the bimetallic strip. The bimetallic strip gradually cools down, and its middle part shrinks and resets, and it is in close contact with the heat collecting main pipe again. The amount of heat transferred to the heat collecting main pipe increases, and the air temperature in the heat collecting main pipe rises. (9) The heated and expanded air enters the right air compression pipe and the right hollow tube column through the second air compression valve, and pushes the second refrigerant compression piston downward, so that the refrigerant at the bottom of the right hollow tube column is compressed and enters the right bypass pipe through the right bypass valve, and then enters the evaporator coil, releasing heat into the building room, causing the indoor air temperature to rise; (10) The refrigerant enters the left bypass pipe and the left hollow tube column from the evaporator coil, pushing the first refrigerant compression piston upward; (11) At the same time, the bimetallic strip continues to absorb heat from solar radiation, and the middle part expands and deforms, then bulges downward, and is no longer in close contact with the heat collecting main pipe. The heat transfer with the heat collecting main pipe decreases, and the air temperature in the heat collecting main pipe decreases. (12) Open the first air compression valve and close the second air compression valve. The entire system operation state is completely restored to the initial state. Then, the above working process is cycled to achieve a continuous heating process.

An evaporating heat insulation layer 26 is provided between the evaporating coil 25 and the bottom floor slab 2.

[0032] like Figure 5 , Figure 6As shown, the lower surface of the heat collecting main pipe 10 is provided with a long straight bimetallic strip 27 with an arc-shaped cross section, and both sides of the outer side of the bimetallic strip 27 are fixedly connected to the outer surface of the heat collecting main pipe 10.

[0034] Preferably, a steerable refractive film may be added above the roof of the building to allow sunlight to irradiate the upper surface of the reflector 9 from a vertical direction as much as possible, thereby concentrating more solar energy on the heat collecting main pipe 10 .

[0035] A door 33 is provided on one side surface of the building.

[0036] Preferably, an auxiliary electric heating system may be used for the heat collecting main pipe 10 to make the heating process more stable, thereby achieving better cooling and heating effects.

[0037] A solar compression temperature control system composite micro-building structure and an operation method thereof are divided into summer working conditions and winter working conditions.

[0038] like Figure 7 , Figure 8 As shown, the operation method in summer is: (1) Open the first air compression valve 12 and close the second air compression valve 13. Open the left condensation valve 20 and close the left bypass valve 22. Open the right bypass valve 22 and close the right condensation valve 20.

[0039] (2) The reflective plate 9 collects solar energy and reflects it to the heat absorbing plate 28 below the heat collecting main pipe 10. After absorbing the heat, the heat absorbing plate 28 transfers the heat to the bimetallic strip 27 in close contact with it, and then transfers the heat collecting main pipe 10 in close contact with the bimetallic strip 27, thereby increasing the air temperature in the heat collecting main pipe 10.

[0040] (3) The air expanded by heat enters the left air compression pipe 11 and the left hollow pipe column 7 through the first air compression valve 12, and pushes the first refrigerant compression piston 15 to move downward, so that the refrigerant at the bottom of the left hollow pipe column 7 is compressed and enters the left condensing coil 18 through the left condensing valve 20. The refrigerant in the condensing coil 18 releases heat by water cooling or air cooling. After the refrigerant is liquefied, it is decompressed by the first expansion valve 23 and then enters the evaporating coil 25 to absorb the indoor heat of the building and reduce the indoor air temperature.

[0041] (4) After the refrigerant is vaporized in the evaporator coil 25, it enters the right bypass pipe 19 and the right hollow pipe column 7, pushing the second refrigerant compression piston 16 to move upward.

[0042] (5) At the same time, the bimetallic strip 27 continues to absorb heat from solar radiation and gradually deforms. Since both sides of the bimetallic strip 27 are fixedly connected to the outer surface of the heat collecting main pipe 10, only the middle part can expand and deform. After the middle part of the bimetallic strip 27 expands and deforms, it bulges downward, so that it is no longer in close contact with the heat collecting main pipe 10, the heat transfer with the heat collecting main pipe 10 decreases, and the air temperature in the heat collecting main pipe 10 decreases.

[0043] (6) Open the second air compression valve 13 and close the first air compression valve 12. Close the left condensation valve 20 and open the left bypass valve 22. Close the right bypass valve 22 and open the right condensation valve 20.

[0044] (7) As the second refrigerant compression piston 16 moves upward, the air in the right air compression pipe 11 is pressed back into the heat collection main pipe 10 .

[0045] (8) Since the bimetallic strip 27 is no longer in close contact with the heat absorbing plate 28 after expansion and deformation, the solar radiation heat absorbed by the heat absorbing plate 28 is difficult to be transferred to the bimetallic strip 27. The bimetallic strip 27 gradually cools down, and its middle part shrinks and resets, and is in close contact with the heat collecting main pipe 10 again. The amount of heat transferred to the heat collecting main pipe 10 increases, and the air temperature in the heat collecting main pipe 10 rises.

[0046] (9) The air that has expanded due to heat enters the right air compression pipe 11 and the right hollow pipe column 7 through the second air compression valve 13, and pushes the second refrigerant compression piston 16 downward, so that the refrigerant at the bottom of the right hollow pipe column 7 is compressed and enters the right condensing coil 18 through the right condensing valve 20. The refrigerant in the condensing coil 18 releases heat by water cooling or air cooling. After the refrigerant is liquefied, it is decompressed by the second expansion valve 24 and then enters the evaporating coil 25 to absorb the indoor heat of the building, thereby reducing the indoor air temperature.

[0047] (10) After the refrigerant is vaporized in the evaporator coil 25, it enters the left bypass pipe 19 and the left hollow pipe column 7, pushing the first refrigerant compression piston 16 to move upward.

[0048] (11) At the same time, the bimetallic strip 27 continues to absorb heat from solar radiation, and its middle portion expands and deforms, and then bulges downward, and is no longer in close contact with the heat collecting main pipe 10. The heat transfer with the heat collecting main pipe 10 decreases, and the air temperature in the heat collecting main pipe 10 decreases.

[0049] (12) Open the first air compression valve 12 and close the second air compression valve 13. Open the left condensation valve 20 and close the left bypass valve 22. Open the right bypass valve 22 and close the right condensation valve 20. The operating state of the entire system is completely restored to the initial state. Subsequently, the above working process is cycled to achieve a continuous refrigeration process.

[0050] like Fig. 9 , Fig.10 As shown, the operation method in winter is: (1) Open the first air compression valve 12 and close the second air compression valve 13. Close the left and right condensation valves 20. Open the left and right bypass valves 22.

[0051] (2) The reflective plate 9 collects solar energy and reflects it to the heat absorbing plate 28 below the heat collecting main pipe 10. After absorbing the heat, the heat absorbing plate 28 transfers the heat to the bimetallic strip 27 in close contact with it, and then transfers the heat collecting main pipe 10 in close contact with the bimetallic strip 27, thereby increasing the air temperature in the heat collecting main pipe 10.

[0052] (3) The air that has expanded due to heat enters the left air compression pipe 11 and the left hollow tube column 7 through the first air compression valve 12, and pushes the first refrigerant compression piston 15 to move downward, so that the refrigerant in the lower part of the left hollow tube column 7 is compressed and enters the left bypass pipe 19 through the left bypass valve 22, and then enters the evaporating coil 25, releasing heat into the building room, causing the indoor air temperature to rise.

[0053] (4) The refrigerant enters the right bypass pipe 19 and the right hollow tube column 7 from the evaporator coil 25, pushing the second refrigerant compression piston 16 to move upward.

[0054] (5) At the same time, the bimetallic strip 27 continues to absorb heat from solar radiation and gradually deforms. Since both sides of the bimetallic strip 27 are fixedly connected to the outer surface of the heat collecting main pipe 10, only the middle part can expand and deform. After the middle part of the bimetallic strip 27 expands and deforms, it bulges downward, so that it is no longer in close contact with the heat collecting main pipe 10, the heat transfer with the heat collecting main pipe 10 decreases, and the air temperature in the heat collecting main pipe 10 decreases.

[0055] (6) Open the second air compression valve 13 and close the first air compression valve 12.

[0056] (7) As the second refrigerant compression piston 16 moves upward, the air in the right air compression pipe 11 is pressed back into the heat collection main pipe 10 .

[0057] (8) Since the bimetallic strip 27 is no longer in close contact with the heat absorbing plate 28 after expansion and deformation, the solar radiation heat absorbed by the heat absorbing plate 28 is difficult to be transferred to the bimetallic strip 27. The bimetallic strip 27 gradually cools down, and its middle part shrinks and resets, and is in close contact with the heat collecting main pipe 10 again. The amount of heat transferred to the heat collecting main pipe 10 increases, and the air temperature in the heat collecting main pipe 10 rises.

[0058] (9) The air that has expanded due to heat enters the right air compression pipe 11 and the right hollow tube column 7 through the second air compression valve 13, and pushes the second refrigerant compression piston 16 to move downward, so that the refrigerant in the lower part of the right hollow tube column 7 is compressed, and enters the right bypass pipe 19 through the right bypass valve 22, and then enters the evaporating coil 25, releasing heat into the building room, causing the indoor air temperature to rise.

[0059] (10) The refrigerant enters the left bypass pipe 19 and the left hollow tube column 7 from the evaporator coil 25, pushing the first refrigerant compression piston 16 to move upward.

[0060] (11) At the same time, the bimetallic strip 27 continues to absorb heat from solar radiation, and its middle portion expands and deforms, and then bulges downward, and is no longer in close contact with the heat collecting main pipe 10. The heat transfer with the heat collecting main pipe 10 decreases, and the air temperature in the heat collecting main pipe 10 decreases.

[0061] (12) Open the first air compression valve 12 and close the second air compression valve 13. The operating state of the entire system is completely restored to the initial state. Subsequently, the above working process is cycled to achieve a continuous heating process.
