Description

Assembly type building and control method thereof
Technical Field
The invention belongs to the technical field of heat exchange, energy conservation and environmental protection, and relates to an assembly type wall system and a heating and ventilation system thereof.
Background
With the continuous development of economy and the large consumption of energy sources, energy conservation becomes a global concern, the utilization of renewable energy sources such as solar energy, wind energy, geothermal energy and the like, industrial waste heat and waste heat becomes a key point for research and development of various countries, however, the energy sources have the characteristics of discontinuity and instability, and therefore, the research of an energy storage technology is particularly important. The heat storage technology is one of energy storage technologies, and an important ring in the heat storage technology is the design of a phase change heat storage heat exchanger. The common phase change heat accumulating heat exchanger has two pipes connected together and cold and hot fluid flows through the inner pipe and the outer pipe separately. The phase change heat storage material is packaged in the phase change heat storage unit with a certain shape and applied to the heat storage box, so that the occupied area of the conventional heat storage box can be reduced, and the defect of discontinuous utilization of waste heat, waste heat and solar energy can be overcome. The flat plate heat exchanger is the heat exchanger with the highest heat exchange efficiency in various heat exchangers at present, and has the advantages of small occupied space and convenience in mounting and dismounting. The high-pressure resistant staggered circulation structure of the plate heat exchanger is formed by combining concave-convex lines between two adjacent plates in a vacuum welding mode, and the staggered circulation structure enables cold and hot fluid in the plate heat exchanger to generate strong turbulence to achieve a high heat exchange effect.
Solar energy is inexhaustible clean energy and has huge resource amount, and the total amount of solar radiation energy collected on the surface of the earth every year is 1 multiplied by 1018kW.h, which is ten thousand times of the total energy consumed in the world year. The utilization of solar energy has been used as an important item for the development of new energy in all countries of the world. However, the solar radiation has a small energy density (about one kilowatt per square meter) and is discontinuous, which brings certain difficulties for large-scale exploitation and utilization. Therefore, in order to widely use solar energy, not only the technical problems should be solved, but also it is necessary to be economically competitive with conventional energy sources.
At present, buildings, industries and traffic become three major industries for energy use, and the energy-saving potential of the building industry is the greatest. The building energy consumption in China accounts for more than 27% of all energy consumption, and the building energy consumption is increased at a speed of 1 percent per year. In the energy consumption of buildings, the energy consumption of the heating air conditioner is the largest and accounts for more than 6 percent of the whole proportion. In global energy consumption, 45 percent of energy is used for meeting the requirements of heat removal, refrigeration, lighting and the like of buildings, and 5 percent of energy is used for the building process of the buildings, so that the energy consumption of the buildings is reduced, the energy consumption of the whole world is reduced, and the consolidation of the whole ecological system is favorably maintained. Under the environment of high-speed and stable development of economy in China, according to continuous improvement of living standard of people and rapid development of urbanization, building energy consumption and renewable energy utilization are urgent problems to be solved in the field of construction, and along with the improvement of the requirement of China on building energy-saving standard, low-energy-consumption buildings become the trend of future development. The development of a solar building integration technology and the improvement of the proportion of renewable energy sources such as solar energy and the like in building energy consumption are important means for realizing social sustainable development in the aims of energy conservation and emission reduction at the present stage. Energy-saving work in China starts late compared with developed countries, energy waste is very serious, and for example, building heating in China consumes heat: the outer wall is 4-5 times of developed countries with similar climatic conditions, the roof is 2.5-5.5 times, and the outer window is 1.5-2.2 times; the air permeability of the door and window is 3-6 times, and the total energy consumption is 3-4 times. In order to reduce energy consumption, the utilization of clean energy sources such as solar photovoltaic photo-thermal energy, wind power generation, tidal power generation and the like is gradually popularized in China at present, and some incentive policies are formulated.
The solar building integration technology is the development direction of the solar technology in the future, and refers to the overall design of bringing the utilization of solar energy into the environment, integrating the building, the technology and the aesthetics into a whole, and the solar facilities become a part of the building and are organically combined with each other, so that the investment can be saved, the integral aesthetic property of the building is not damaged, and the integration problem of the facilities and the building can be utilized to the maximum extent. The application of the solar building integration technology in heating can further reduce the building energy consumption. However, in the current practical engineering application, on one hand, the beauty of a building cannot be fully ensured, and meanwhile, the space occupancy rate of a wall body is possibly overlarge, so that the assembly efficiency of the building structure is reduced, and on the other hand, the problem of low solar heat efficiency utilization rate exists.
An air ventilation processing device is arranged in a solar building, an air heat source is taken as a low-temperature heat source in a heat pump mode at present, electric energy or superheated steam is taken as a high-temperature heat source, quality improvement and temperature rise are carried out through the heat pump, and utilization of solar energy is achieved. However, the thermodynamic system has more complex equipment composition and higher initial investment cost, wherein the closed thermodynamic system belongs to an indirect heat exchange mode and cannot realize further condensation and extraction of water vapor; the open thermodynamic system absorbs solution and air direct contact reaction, and impurity granule in the air will get into and absorb solution and cause the pollution of solution, and then leads to scaling or jam in the pipeline, and system reliability is relatively poor.
For the above analysis, the following technical problems exist in the prior art: the integrated building wall has low solar energy utilization efficiency, the space occupancy rate of the wall may be too large, and the assembly efficiency of the building structure is reduced, so that improvement is needed.

Preferably, when the detected air temperature is lower than the set temperature and/or pressure lower limit, the controller controls the first pump 9 to decrease the power, thereby reducing the amount of the heat sink entering the heat exchanger and increasing the temperature and pressure of the air output from the heat exchanger 3.
Preferably, when the detected air temperature is higher than the set upper temperature and/or pressure limit, the controller controls the power of the first pump 9 to be increased, thereby increasing the amount of the cold source entering the heat exchanger, and thus decreasing the temperature and pressure of the air output from the heat exchanger 3.

As a modification, the heat exchanger 3 is provided with a horizontal baffle extending over the entire cross-section of the housing of the heat exchanger 3, the baffle being arranged between the shower and the air inlet of the heat exchanger, the baffle being provided with fluid openings through which the air flows upwards while the water flows downwards from below.
According to the invention, the baffle is arranged, so that the sprayed fluid and air can stay on the baffle for more time, and the heat exchange time is prolonged. Meanwhile, gas and liquid can be subjected to concentrated heat exchange in the fluid holes, and the occurrence of a heat exchange short circuit area is avoided.
Preferably, the baffle is provided in plurality. Through a plurality of baffles, fluid flows out of the baffles through the fluid holes, enters the next baffle space, stays for more time between the baffles, and continues to exchange heat. The heat can be fully and continuously utilized.
Preferably, the uppermost and lowermost baffles have a non-uniform distribution of fluid hole distribution density. The distribution density of the through-flow holes is increasing from the centre of the uppermost and lowermost baffle to the location where the baffles are connected to the shell of the heat exchanger 3. Because the fluid distributed in the center is the most and the fluid distributed from the center to the outside is reduced no matter the spray head is in spraying or air input, the fluid holes are unevenly distributed, so that the fluid holes can be evenly distributed in the process of flowing upwards and downwards through the fluid holes, and the damage caused by overhigh local temperature is avoided.
Preferably, the distribution density of the through-flow holes increases from the center of the baffle plate to the connecting position of the baffle plate and the shell. Through the arrangement, the requirement of uniform fluid distribution can be further met.
Preferably, the horizontal baffle plates are of two types, the first type is that the distribution density of the through holes is increased from the center of the baffle plate to the edge of the baffle plate (the connecting position of the baffle plate and the heat exchanger shell). In the second type, the distribution density of the through-flow holes is reduced from the center of the baffle to the edge of the baffle (the position where the baffle is connected with the housing). A plurality of parallel baffles are arranged along the height direction, and the types of the adjacent baffles are different. The baffles are formed into baffle-like forms by arranging adjacent baffles to be different in type. The fluid flow in the center or around of the previous baffle is the largest, and after the fluid flows into the next baffle, the fluid needs to flow to the around or the center, so that the flow path of the fluid is increased, the fluid can be fully contacted with the heat exchange component, and the heat exchange effect is improved.

Preferably, the spacing between adjacent baffles increases from the lower portion to the upper portion and then begins to decrease at a certain location.
The certain position is preferably an intermediate position between the shower and the heat exchanger air inlet.
Through the setting, the air temperature of the air inlet is the highest, and the number of the lower baffles is the largest through the continuous increase of the distance between the baffles, so that the air between the lower baffles and the water exchange is more sufficient. Similarly, because the temperature of shower water is the lowest, constantly increases through the interval between the water flow direction baffle for upper portion baffle quantity is the most, makes more abundant heat transfer between the air between the baffle on upper portion and the water. Through foretell setting for satisfy the heat transfer effect against current more between the above-mentioned heat exchanger, make the heat exchange efficiency between two entrances the highest, heat transfer time is the longest, and for normal heat transfer effect against current, the heat transfer effect is better, can further improve heat exchange efficiency.
Preferably, the spacing between adjacent baffles increases with increasing magnitude from the lower portion to the upper portion, and then begins decreasing with increasing magnitude at a certain location. The amplitude of the structure is also the result of a large number of experiments and numerical simulation, and the heat exchange efficiency is further improved by about 7%.
Preferably, in order to prevent air from flowing out through the bottom pipeline of the heat exchanger, a certain liquid level height is required to be kept in the reaction tower as a liquid seal, and the liquid level height is the distance from the liquid level of the cooling water to the second pressure control device and can be set to be 1 m. At this time, the second pressure control device sets the pressure parameter as the difference between the positive pressure value in the heat exchanger and the liquid level height water head.
Preferably, the heat exchanger 3 is made of a pressure-resistant material such as stainless steel because the temperature of the air flowing through the heat exchanger is high and the internal pressure of the air is higher than the pressure of the external environment. The pressure in the heat exchanger is the sum of the supercharging amount of the air pressure adjusting device and the ambient pressure, and can be adjusted and controlled through pressure control devices arranged at an upper side air outlet and a lower side cooling water outlet of the heat exchanger.
Preferably, the demister 8 and demister 4 are arranged above the interior of the heat exchanger 3 for filtering out liquid droplets entrained with the air. The defoaming device can be a silk screen defoaming device and a demisting device can be a baffle plate type demisting device.

Because recirculated cooling water adopts the form of spraying to get into heat exchanger, inside air is with the cooling water reverse contact and the velocity of flow is higher, and accessible defogging device is fixed with the entrapment of defoaming device to large granule liquid drop.
The second pump 11 is used for raising the pressure of the circulating water in the pipeline. The pressure provided by the first pump 9 is used for ensuring the working state of a spraying device, preferably a nozzle in the heat exchanger 3, and the pressure and flow parameters are determined by the spraying working condition of the nozzle. The pressure provided by the second pump 11 is used for ensuring the flowing heat exchange state of the circulating water in the heat output device 10, and the pressure, the temperature and the flow parameters are fed back and adjusted by the thermodynamic calculation result of the heat output device. The thermodynamic calculation is calculated by the gas-liquid energy balance of the heat exchanger 3.
The pressure control device 5 and the pressure control device 16 are used for controlling pressure parameters in the heat exchanger, and can be selected from a self-standing pressure regulating valve or a digital pressure regulating valve. Because the system is continuously air inlet, the intermittent pressure control is carried out by utilizing a self-standing pressure regulating valve or a digital pressure regulating valve. The pressure regulating valve adopts a post-valve decompression mode, and the pressure control value is consistent with the set value of the air pressure regulating device. When the pressure in the heat exchanger is lower than a set value, the regulating valve is in a closed state, the boosted air is enriched in the heat exchanger, and the internal pressure is gradually increased; when the pressure in the heat exchanger is higher than a set value, the regulating valve is in an open state, air leaves the heat exchanger through the regulating valve, the internal pressure is gradually reduced, the regulating valve is reset, and the closed state is finally recovered.
The heat output device 10 is a user-side heat utilization device, and can adopt a common heat exchange mode to utilize the heat of circulating water. This example uses a domestic radiator heating process as the heat utilization device. The radiator can be used for heating of prefabricated buildings, such as fig. 4, and also for heating of other buildings, such as fig. 3.
The water tank 13 is used for storing circulating water of the system and has a buffering effect, and meanwhile, the running temperature of the system can be adjusted by controlling the flow of the circulating water. After gas-liquid heat exchange is carried out on the circulating water in the heat exchanger 3, the circulating water flows into the lower water tank 13 under the action of pressure in the tower. As trace impurities, particles and the like in the air are dissolved in the circulating water during the operation of the system, the trace impurities, the particles and the like are enriched in the circulating water after long-term operation, and a water treatment device and a filtering device are required to be arranged in the water tank.
The dosing water replenishing port 14 is arranged at the bottom of the water tank 13 and used for feeding impurity treatment agents, and dosing modes such as timed feeding, continuous feeding and the like can be adopted.
The water intake 12 is also arranged at the bottom of the water tank 13, and the system can extract water vapor in the air to enter circulating water, so that the quality balance of the original water in the system can be broken by long-term operation, and the recovered water needs to be extracted. Meanwhile, the water intake 12 can also be used for discharging circulating water in the water tank 13.
The filtering device 15 is located inside the water tank 13 and is used for filtering particulate matters or precipitated matters with larger particle sizes.
A solar energy air source thermal work method comprises the following steps: air heated in the heater, particularly wet air, enters the air pressure adjusting device 2 to adjust air pressure parameters, so that the air pressure can be increased, the air temperature is increased along with the increase of the air temperature, then the air is introduced into the heat exchanger 3, the air and circulating water are subjected to direct contact type heat exchange, the air is cooled to release sensible heat, and water vapor in the air further releases latent heat of vaporization after reaching a saturated state. The pressure control device 5 is arranged above the heat exchanger 3, and the pressure control device 16 is arranged below the heat exchanger 3 and used for controlling the pressure in the heat exchanger 3 to be stable. The cooled saturated wet air passes through the demisting device 4 and the demisting device 8 to remove fog drops with larger particle sizes, then enters the turbine 6, pushes the turbine impeller to rotate by means of the expansion force in the gas pressure release process, drives the generator to generate power or outputs mechanical energy to coaxially drive the fan motor to do work, and finally enters the heater to be circularly heated in a normal pressure state. The circulating water and air carry out contact heat exchange in the heat exchanger 3, the circulating water after heating flows back to the water tank 13 under the action of pressure, and after processes such as filtration, dosing reaction and the like, the circulating water is pressurized in the circulating water pump 11 and then is pumped to the heat output device 10 to release heat. The cooled circulating water is pressurized by the first pump 9 and then enters the heat exchanger 3 to be sprayed to complete circulation.
After the saturated humid air is boosted by the air pressure adjusting device, the water vapor in the humid air is changed into a superheated state from a saturated state, and the dew point temperature of the humid air is increased along with the increase of the pressure. Because the temperature of the circulating water is far lower than that of the superheated air, after the gas and the liquid are directly contacted, the superheated air is cooled to the saturation temperature of the vapor under the pressure, and the sensible heat of the air is released in the process; the saturated air is further cooled and released heat by the gas-liquid temperature difference, and sensible heat of dry air components and latent heat of vaporization of water vapor are released in the stage.
Due to the increase in the dew point of the humid air, the amount of condensable water condensed to the same temperature is increased as compared to the conventional normal pressure contact condenser. Therefore, the recovery of the water vapor in the humid air can be realized.
The atomized circulating water drops and the small-particle-size condensed water drops can be used as crystal nuclei to adsorb impurity gas molecules and particles in the air, the diffusion effect is further promoted under the pressurization effect, and the adsorption capacity is enhanced. After the temperature is reduced, the air leaves the heat exchanger and enters the turbine, and the fan motor is driven to do work by expandable power generation or output mechanical energy coaxially. The temperature of the air after the pressure release to the normal pressure is further lowered. The circulating water absorbs the sensible heat of air and the vaporization latent heat of water vapor in the contact process, the temperature of the circulating water is increased, and the circulating water is used as an output heat source to supply heat to the outside after leaving the heat exchanger.
The second pump is used for increasing the pressure of circulating water in the pipeline, and a centrifugal pump can be adopted. The pressure provided by the first pump is used for ensuring the working state of the nozzles in the air-water heat exchanger, and the pressure and the flow parameters are determined by the spraying conditions of the nozzles. The pressure provided by the second pump is used for ensuring the flowing heat exchange state of circulating water in the heat output device, and the pressure and flow parameters are determined by the thermodynamic calculation result of the heat output device.
The pressure control device is used for controlling pressure parameters in the air-water heat exchanger and selects a self-supporting pressure regulating valve.
The water tank is positioned below the air-water heat exchanger and the pressure control device, is used for storing circulating water of the system, plays a role in buffering, and can adjust the operating temperature of the system through the flow of the circulating water. Circulating water is subjected to gas-liquid heat exchange in the air-water heat exchanger and then flows into a lower water tank under the action of pressure in the tower. As trace impurities, particles and the like in the air are dissolved in the circulating water during the operation of the system, the trace impurities, the particles and the like are enriched in the circulating water after long-term operation, and a water treatment device and a filtering device are required to be arranged in the water tank. The bottom of the water tank is provided with a dosing water replenishing port and a water intake port.
The dosing water replenishing port is arranged at the bottom of the water tank and used for feeding impurity treatment agents in a timed dosing mode. The water intake is also arranged at the bottom of the water tank and is used for extracting the water recovered by the system and discharging the circulating water in the water tank. The filtering device is positioned inside the water tank and used for filtering particulate matters or precipitated substances with larger particle sizes.

(3) Compared with an indirect heat exchange mode, the contact heat exchange can effectively reduce the end difference of the heat exchanger, effectively improve the outlet temperature of the heat absorbing medium and has more obvious energy upgrading effect.
(4) After heat exchange, air is released to push the impeller to do work, gas expansion force is converted into mechanical energy to drive the generator to generate electricity or output mechanical energy to coaxially drive the fan motor to do work, and finally the air enters the heater to be circularly heated in a normal pressure state, so that the gradient effective utilization of energy is further realized.
In the whole process of the system, the utilization of air heat energy, the recovery of moisture in the air and the capture of impurity components can be realized, and the system has extremely strong engineering practice significance.
