Description

Background
The energy problem is the first problem of socioeconomic development. In recent years, along with rapid development of economy, the demand of China for energy shows a rapid increase trend. Because the low energy utilization efficiency of China and the overlarge use proportion of fossil energy such as coal and the like, the energy problem of China is more severe and the environmental damage is more serious day by day, thereby greatly restricting the economic development of China. Solar energy is an important alternative to traditional energy sources because of its renewable and environmentally friendly advantages. At present, the building energy consumption, the industrial energy consumption and the traffic energy consumption are combined into three major energy consumption households in China, and particularly, the building energy consumption is in a sharp rising trend along with the continuous rising of the total building amount and the rising of the living comfort level. According to statistics, the building energy consumption accounts for about 30% of the total social energy consumption, wherein the most important energy consumption is heating and air conditioning, and accounts for 20%. The "30%" is the proportion of energy consumed by the building during construction and use, and if the energy consumed by the building material production process is added (accounting for 16.7% of the total social energy consumption), the energy consumption related to the building accounts for 46.7% of the total social energy consumption. The building load is mainly the cold and hot load, and the integration of the solar building is a feasible way for reducing the building load.
Although the solar heat collection technology is relatively mature, the solar heat collection system is in an idle state at night due to the influence of changing day and night, so that the use efficiency of the solar heat collection system is greatly reduced; on the other hand, radiation refrigeration also has the defects that the cost is high due to low power, the refrigeration effect of the radiation refrigeration device is difficult to realize in the daytime, and the like.
The existing heating and refrigerating composite device has the following defects: (1) the heat transfer pipeline of the general building integrated solar heat collector is too long, so that the heat loss in the heat transfer process is improved, the integral performance of the system is influenced, and the manufacturing cost is higher. (2) The function is single, and the daily needs of users can not be satisfied only by heating or only refrigerating. (3) In the daytime, the radiation refrigeration process can carry out heat convection and heat radiation with the environment, so that the daytime refrigeration benefit is not high. (4) The start and stop of the refrigeration system can not be automatically controlled. (5) Instability of solar thermal collection devices. (6) The device has the advantages of complex structure, high processing difficulty and high preparation cost.

In summary, when in use, the following modes are divided:
night radiation cooling mode
Referring to fig. 6, at night without solar radiation, the heat collection-radiation refrigeration composite membrane 104b has high emissivity and low absorptivity for an atmospheric window waveband of 8-13 μm, and by using the performance, the self heat of the heat collection-radiation refrigeration composite membrane 104b can be discharged to an external space with the temperature close to absolute zero through the atmospheric window in the form of 8-13 μm electromagnetic waves, so that the self temperature is reduced, the temperatures of the substrate 101 and the heat dissipation heat pipe condensation section 103b are sequentially reduced through heat conduction, the temperature difference is caused between the heat dissipation heat pipe condensation section 103b and the heat dissipation heat pipe evaporation section 103a, and the heat dissipation heat pipe 103 is started to work through the temperature difference; after the working medium of the heat dissipation heat pipe condensation section 103b is cooled and condensed, due to the action of gravity, the condensed working medium flows to the heat dissipation heat pipe evaporation section 103a in a liquid state, and evaporates into a gaseous working medium after the heat dissipation heat pipe evaporation section 103a absorbs heat, and the vaporized gaseous working medium flows upwards to the heat dissipation heat pipe condensation section 103b, so that a closed cycle is completed in the heat dissipation heat pipe 103, and simultaneously the heat of water in the cold water tank 106 is absorbed. Each closed cycle of the heat-dissipating heat pipe 103 absorbs the heat of the water in the cold water tank 106, and reduces the temperature of the water in the cold water tank 106.
It should be noted that the radiation cooling function is generally started in summer with a high temperature, and is generally selected to be turned off in other seasons with a low temperature.
Day solar heat collection mode
Referring to fig. 7, in the daytime with solar radiation, the heat collection-radiation refrigeration composite membrane 104b has high absorptivity and low emissivity for radiation wave bands except for an atmospheric window of 8-13 μ M, and by utilizing the performance, solar radiation can be absorbed, the temperature of the heat collection-radiation refrigeration composite membrane is increased, the solar radiation firstly reaches the surface of the PE membrane 104a, and because the PE membrane 104a has good penetrability for the solar radiation and prevents the self radiation of the heat collection-radiation refrigeration composite membrane 104b from diffusing to the surrounding environment, a greenhouse effect is formed in the air interlayer M; solar radiation is reflected for multiple times in the air interlayer M, finally most solar radiation energy is absorbed by the heat collection-radiation refrigeration composite membrane 104b, the absorbed heat is transferred to the heat transfer heat pipe evaporation section 102a welded on the back of the substrate 101 in a heat conduction mode, so that working media of the heat transfer heat pipe evaporation section 102a are heated and evaporated, the evaporated working media flow to the heat transfer heat pipe condensation section 102b, and the latent heat is released and condensed into liquid working media; after being influenced by self gravity, the liquid working medium flows back to the evaporation section 102a of the heat transfer heat pipe, so that a closed cycle is completed in the heat transfer heat pipe 102. Each closed cycle in the heat transfer heat pipe 102 transfers the latent heat released by the working medium to the domestic water in the hot water tank 105, and the water temperature in the hot water tank 105 is increased.
Spring and autumn winter operation mode
The solar heat collection function is started in spring and autumn in winter, solar radiation is absorbed through the heat collection-radiation refrigeration composite membrane 104b, domestic water in the hot water tank 105 is heated, the heated domestic water is stored in the hot water tank 105 for later use, and the pipeline can be controlled to convey the domestic water into a room for users to use when the hot water is needed.
Summer operation mode
The solar heat collection and radiation refrigeration function is started in summer, and the heat collection-radiation refrigeration composite film 104b absorbs solar radiation in the daytime. When no solar radiation exists at night, the heat collection-radiation refrigeration composite membrane 104b discharges the heat of the heat collection-radiation refrigeration composite membrane to the outer space with the temperature close to absolute zero through the atmospheric window in the form of 8-13 mu m electromagnetic waves, reduces the water temperature in the cold water tank 106, and stores the water in the cold water tank 106 for later use. When a user feels that the room temperature is too high, the cold water in the cold water tank can be controlled to be transported to the upper part of the indoor wall through the pipeline, the temperature difference is formed between the cold water and the hot air above the indoor wall, heat exchange is carried out, and then the indoor temperature is reduced.
