Description

Technical Field

[0001] The invention relates to the technical field of building thermal insulation, and in particular to a thermal insulation system of a building and a thermal insulation method thereof. Background Art

[0002] Buildings refer to structures built by humans for living, working, entertainment or other purposes. Their design and construction need to comprehensively consider functions, safety, comfort, energy saving and other aspects. Buildings of different types and uses have different characteristics and requirements, but the common goal is to provide humans with a practical and beautiful living and working environment. The surface of current buildings is usually covered with thermal insulation materials to achieve the thermal insulation effect of the building. However, due to the "rising in the east and setting in the west" of the sun, when the sun rotates with the building as a reference, the sunlight will not continue to irradiate the wall on one side of the building. Therefore, after the wall of the building is covered with thermal insulation materials, it is not easy to cause the temperature in the building to rise. The top of the building will be continuously exposed to the sun. Therefore, compared with the wall, the top of the building will be continuously exposed to the sun, so the temperature is relatively high, which is easy to cause the temperature in the building to rise sharply, affecting the people indoors. At the same time, because the top of the building is continuously exposed to sunlight, the time in a high temperature state is relatively long, so the thermal insulation material on the top of the building will be in a high temperature environment for a long time, which will accelerate the aging of the thermal insulation material and affect the service life of the insulation material. Summary of the invention

[0003] The present invention is intended to provide a building insulation system and a building insulation method thereof, so as to solve the problem that the top of the building is continuously irradiated by sunlight, the temperature rises and affects the temperature inside the building.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a heat insulation system for a building, comprising a roof, a heat insulation mechanism and a control mechanism, wherein the heat insulation mechanism comprises a water tank and a heat reflection layer laid on the roof surface, and a heat conduction pipe for absorbing the heat of the heat reflection layer is laid on the lower surface of the heat reflection layer; the water tank is connected to a water pipe, a water pump is installed in the water tank, a water outlet of the water pump is connected to a drain pipe, an end of the drain pipe away from the water pump passes through the water tank and is connected to a water inlet end of the heat conduction pipe, a heat preservation box is arranged under the roof, and a water outlet end of the heat conduction pipe passes through the heat preservation box and is connected to the inside of the heat preservation box;

[0005] The control mechanism includes a controller and a temperature sensor. The temperature sensor is electrically connected to the controller. The controller is electrically connected to the water pump. The controller is electrically connected to a solenoid valve. The solenoid valve is installed at the connection between the water tank and the tap water pipe.

[0006] Furthermore, the roof is a "human"-shaped roof, and there are two heat pipes, which are respectively arranged on two inclined surfaces of the roof, and both heat pipes are installed on the lower surface of the heat reflecting layer in a serpentine routing manner. The water inlet end of the heat pipe is located at the bottom end of the roof, and the water outlet end of the heat pipe passes through the top of the roof and then communicates with the inside of the insulation box.

[0007] Furthermore, there are two water pumps, the water outlets of the two water pumps are respectively connected to drainage pipes, and the two drainage pipes are respectively connected to the water inlet ends of the two heat conduction pipes.

[0008] Furthermore, the number of the temperature sensors is six, and the temperature sensors are installed in two heat pipes in groups of three. The three temperature sensors in the same group are respectively located at the bottom, middle and top of the roof.

[0009] Furthermore, the temperature sensor is a miniature temperature sensor.

[0010] Furthermore, the controller is a single chip microcomputer.

[0011] Furthermore, a water pipe is provided at the bottom of the heat preservation box, and the water pipe is connected to a water valve in the building.

[0012] A method for heat insulation of a building, comprising the following steps:

[0013] Step 1: Start two water pumps through the controller, and pump the clean water in the water tank into the two heat pipes through the operation of the water pumps until the clean water in the heat pipes is filled to the top of the roof and then the water pumps stop running;

[0014] Step 2: The heat is reflected by the heat reflective layer on the roof. When the temperature of the heat reflective layer rises under the continuous irradiation of sunlight, the heat pipe absorbs the heat of the heat reflective layer by heat transfer;

[0015] Step 3: After the temperature of the heat pipe rises, the clean water in the heat pipe absorbs the heat of the heat pipe, and the temperature of the clean water in the heat pipe rises. Since the density of hot water is relatively lower than that of cold water, the hot water in the heat pipe will gradually flow to the top of the heat pipe.

[0016] Step 4: When the water temperature in the heat pipe reaches the set control temperature, the temperature sensor at the top of the heat pipe transmits the monitored temperature signal to the controller. After receiving the temperature signal, the controller starts the water pump corresponding to the heat pipe. The water pump runs slowly to inject clean water in the water tank into the heat pipe. With the injection of clean water, the hot water in the heat pipe is gradually pushed out of the heat pipe and flows into the insulation box. At this time, the newly injected clean water causes the temperature of the heat pipe to drop rapidly.

[0017] Step 5: If the temperature of the clean water in the heat pipe rises quickly, the hot water in the pipe that exceeds the set control temperature gradually spreads from the top of the heat pipe to the bottom of the heat pipe. The three temperature controllers simultaneously transmit the monitored temperature signals to the controller. After receiving the three temperature signals, the controller increases the water delivery speed of the water pump to speed up the replacement of the hot water in the heat pipe by the water pump.

[0018] Step six, when the temperature sensor at the top of the heat pipe detects that the water temperature is lower than the set control temperature, the temperature sensor transmits the monitoring signal to the controller, and the controller controls the water pump to stop running.

[0019] Beneficial effects of the present invention:

[0020] 1. This solution first reflects heat through the heat reflection layer to reduce the heat input to the building. When the heat reflection layer heats up due to continuous sunlight, the temperature of the heat reflection layer is absorbed by the heat pipe to reduce the temperature of the heat reflection layer. The temperature of the heat pipe is absorbed by the clean water in the heat pipe to ensure that the heat pipe is maintained in a relatively low temperature range. The water temperature is then monitored by a temperature sensor. When the water temperature is too high, the water pump is started to inject clean water to squeeze out the hot water in the heat pipe. This effectively separates the heat increased by long-term sunlight from the top of the building, solving the problem of temperature increase affecting the internal temperature of the building.

[0021] 2. Through the operation of the water pump, clean water is injected into the heat pipe to squeeze out the hot water in the heat pipe, so that the heat pipe can be kept at a lower temperature. This can ensure that the heat pipe can continue to efficiently absorb the heat from the heat reflective layer, thus having the technical effect of continuous heat insulation.

[0022] 3. The hot water that absorbs heat is discharged into the insulation box for collection, and then connected to the water valve in the building. In this way, the water valve can be opened when hot water is needed. This effectively utilizes hot water, saves the consumption of electricity, natural gas and other energy sources, and reduces the cost of using hot water in the building.

[0027] The following is further described in detail through specific implementation methods:

[0028] The reference numerals in the drawings of the specification include: temperature sensor 1, heat reflection layer 2, heat conduction pipe 3, roof 4, insulation box 5, water tank 6, drain pipe 7, water pump 8, solenoid valve 9, water pipe 10, water outlet 11.

[0029] The embodiment is basically as shown in the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown:

[0030] A heat insulation system for a building comprises a roof 4, a heat insulation mechanism and a control mechanism. The roof 4 is a "human" shaped roof 4. The heat insulation mechanism comprises a water tank 6 and a heat reflection layer 2 laid on the surface of the roof 4. Two copper heat conduction pipes 3 for absorbing heat from the heat reflection layer 2 are laid on the lower surface of the heat reflection layer 2. The two heat conduction pipes 3 are respectively arranged on two inclined surfaces of the roof 4, and the two heat conduction pipes 3 are installed on the lower surface of the heat reflection layer 2 in a serpentine routing manner. The spacing between the heat conduction pipes 3 is 0-5 mm (preferably 3 mm), the diameter of the heat conduction pipes 3 is 1-2 cm (preferably 1.5 cm), and the water inlet end of the heat conduction pipe 3 is located at the bottom end of the roof 4. The water tank 6 is connected to the water pipe. Two water pumps 8 are installed in the water tank 6. The water outlet of each water pump 8 is connected to a drain pipe 7. One end of the drain pipe 7 away from the water pump 8 passes through the water tank 6 and is connected to the water inlet end of a heat conducting pipe 3. An insulation box 5 is arranged below the roof 4. The water outlet ends 11 of the two heat conducting pipes 3 pass through the insulation box 5 and are connected to the insulation box 5. A water delivery pipe 10 is arranged at the bottom of the insulation box 5. The water delivery pipe 10 is connected to a water valve in the building.

[0031] The control mechanism includes a controller (single-chip microcomputer) and six temperature sensors 1 (micro temperature sensors, brand: Capeson; model: CXCWX-TK). The six temperature sensors 1 are all electrically connected to the controller. The temperature sensors 1 are installed in two heat pipes 3 in groups of three. The three temperature sensors 1 in the same group are respectively located at the bottom, middle and top of the roof 4. The controller is electrically connected to two water pumps 8. The controller is electrically connected to a solenoid valve 9, which is installed at the connection between the water tank 6 and the tap water pipe.

[0032] The specific implementation process is as follows:

[0033] Before use, when using, the controller first controls the solenoid valve 9 to open to fill the water tank 6 with clean water. After the water tank 6 is filled with clean water, the controller controls the solenoid valve 9 to close, and then the controller starts the two water pumps 8. The two water pumps 8 run to pump the clean water in the water tank 6 into the two heat pipes 3. When the liquid level of the clean water rises to the top of the heat pipe 3 and reaches the temperature controller at that location, the controller controls the water pump 8 to stop running. Under the continuous irradiation of sunlight, when the heat reflection layer 2 reaches the limit of temperature reflection and begins to heat up, the two heat pipes 3 absorb the heat on the heat reflection layer 2 by heat transfer, and the clean water in the heat pipe 3 absorbs the heat on the heat pipe 3 and turns into hot water. The density of hot water is relatively small, so it slowly floats up in the heat pipe 3 and gathers at the top of the roof 4. As the heat pipe 3 continues to absorb heat, the temperature of the hot water gradually increases. When the temperature sensor 1 at the top of the roof 4 detects that the water temperature has reached the set temperature upper limit, the temperature sensor 1 at that location will set the temperature The temperature model is transmitted to the controller, and the controller controls the water pump 8 corresponding to the heat pipe 3 to start. The water pump 8 runs to slowly inject the clean water in the water tank 6 into the water inlet end of the heat pipe 3. As the water inlet end of the heat pipe 3 enters, the hot water at the top of the heat pipe 3 is pushed out by the clean water and discharged from the water outlet end 11 of the heat pipe 3 into the heat preservation box 5 for insulation to prevent water temperature loss. When the clean water with lower temperature flows to the temperature sensor 1 at the top of the roof 4, the temperature sensor 1 detects that the water temperature has dropped, and then transmits the temperature signal to the controller. At this time, the controller controls the water pump 8 to stop running. When hot water is needed, the water valve can be opened to discharge the hot water in the heat preservation box 5 for use.

[0034] If the temperature of the clean water in the heat pipe 3 rises quickly, the hot water in the pipe that exceeds the set control temperature gradually spreads from the top of the heat pipe 3 to the bottom of the heat pipe 3, and the three temperature controllers simultaneously transmit the monitored temperature signals to the controller. After receiving the three temperature signals, the controller increases the water delivery speed of the water pump 8 to speed up the replacement of the hot water in the heat pipe 3 by the water pump 8.

[0035] A method for heat insulation of a building, comprising the following steps:

[0036] Step 1: Start two water pumps through the controller, and pump the clean water in the water tank into the two heat pipes through the operation of the water pumps until the clean water in the heat pipes is filled to the top of the roof and then the water pumps stop running;

[0037] Step 2: The heat is reflected by the heat reflective layer on the roof. When the temperature of the heat reflective layer rises under the continuous irradiation of sunlight, the heat pipe absorbs the heat of the heat reflective layer by heat transfer;

[0038] Step 3: After the temperature of the heat pipe rises, the clean water in the heat pipe absorbs the heat of the heat pipe, and the temperature of the clean water in the heat pipe rises. Since the density of hot water is relatively lower than that of cold water, the hot water in the heat pipe will gradually flow to the top of the heat pipe.

[0039] Step 4: When the water temperature in the heat pipe reaches the set control temperature, the temperature sensor at the top of the heat pipe transmits the monitored temperature signal to the controller. After receiving the temperature signal, the controller starts the water pump corresponding to the heat pipe. The water pump runs slowly to inject clean water in the water tank into the heat pipe. With the injection of clean water, the hot water in the heat pipe is gradually pushed out of the heat pipe and flows into the insulation box. At this time, the newly injected clean water causes the temperature of the heat pipe to drop rapidly.

[0040] Step 5: If the temperature of the clean water in the heat pipe rises quickly, the hot water in the pipe that exceeds the set control temperature gradually spreads from the top of the heat pipe to the bottom of the heat pipe. The three temperature controllers simultaneously transmit the monitored temperature signals to the controller. After receiving the three temperature signals, the controller increases the water delivery speed of the water pump to speed up the replacement of the hot water in the heat pipe by the water pump.

[0041] Step six, when the temperature sensor at the top of the heat pipe detects that the water temperature is lower than the set control temperature, the temperature sensor transmits the monitoring signal to the controller, and the controller controls the water pump to stop running.
