The working principle of the absorption type solar condensation automatic temperature adjustment radiation system for the cold areas is as follows: in the daytime, the sunlight irradiates strongly, irradiates on the condenser 2, is collected by the condenser 2 and enters the first communication pipeline 3, and reaches the lower part through the first communication pipeline 3 to heat the high-concentration mixed liquid 15 in the first communication pipeline 3. The high-concentration mixed liquid 15 is heated to a higher temperature and boiling, and the low-concentration mixed liquid 14 outside the first communication pipeline 3 has a lower temperature and a higher density, while the gas-liquid mixture in the first communication pipeline 3 has a lower density, so that the gas-liquid mixture can reach the liquid spraying hole 32 along the first communication pipeline 3 according to the principle of the communicating vessel and is sprayed out from the liquid spraying hole 32. The gas and the liquid in the sprayed gas-liquid mixture start to separate, the sprayed high-concentration mixed liquid (the high-concentration absorbent is gasified when the absorbent in the high-concentration mixed liquid is completely gasified) is stored in the liquid storage tank 13, the gaseous absorbent rises to the liquid storage tank 1 at the upper part of the liquid storage tank 12, and the gaseous absorbent is condensed into liquid drops to be attached to the pipe wall at the upper part of the liquid storage tank 1 due to the fact that the upper part of the liquid storage tank 1 is close to the outside temperature, and the liquid drops flow into the liquid storage tank 12 along the pipe wall at the upper part of the liquid storage tank 1 along with the continuous increase of the liquid drops.
When the sunlight irradiates at night, the high-concentration mixed liquid in the liquid storage tank 13 (the high-concentration absorbent is used for the purpose of heating the room at night if the absorbent in the high-concentration mixed liquid is gasified completely) starts to cool, and because the concentration of the solution in the liquid storage tank 13 is high, the absorbent vapor can be absorbed, so that the concentration of the absorbent vapor in the liquid storage tank 1 is reduced, the absorbent in the liquid storage tank 12 is evaporated, heat can be emitted when the absorbent vapor is absorbed, and the heat is transferred into the room through the heat storage layer 4, so that the system is more suitable for cold areas and realizes automatic radiation temperature regulation. The concentration of the liquid in the liquid storage tank 13 becomes smaller after absorbing the absorbent, the volume becomes larger, and the liquid overflows into the low-concentration mixed liquid 14 in the liquid storage tank 1. Thus achieving the purpose of recycling.
According to the absorption type solar condensation automatic temperature-regulating radiation system for the cold areas, the traditional roof/wall surface is combined with the absorption technology through the arrangement of the liquid storage tank and the like, and the solar condenser is installed to generate high-temperature heat energy, so that the absorption type automatic temperature-regulating radiation unit is driven, and the purpose of automatic radiation temperature regulation is achieved.

By providing cold or heat to the room in the form of radiation, its indoor thermal environment is more comfortable. By utilizing clean energy solar energy to provide cold or heat for the room, compared with the traditional refrigerating and heating modes such as fire coal, the device has the advantage of less pollution to the external environment.
Preferably, as shown in fig. 4, a condensation layer 11 is laid on the pipe wall above the liquid collecting groove 12 of the liquid storage tank 1. The condensation layer 11 has the effect of promoting condensation of the gaseous absorbent and increasing the condensation rate. The condensation layer 11 can be parallel to the wall of the liquid storage tank 1, or can be arranged at a certain angle with the wall of the liquid storage tank 1, so that the upper part of the liquid storage tank 1 forms a sharp top which gradually reduces from bottom to top, and the liquid collection rate is improved.

The heat dissipation layer 5 is laid and connected on the outdoor surface of the wall, covers the upper tank body above the liquid level of the low-concentration mixed liquid of the liquid storage tank 1, and the heat dissipation layer 5 is a hollow channel for realizing the heat dissipation effect.

In operation, during daytime, the first valve 511 is closed, the second valve 512 is opened, and indoor circulating air is introduced into the first heat dissipation layer 51. The heat released when the upper pipe wall of the liquid storage tank 1 condenses out the absorbent liquid heats the air entering the first heat dissipation layer 51 from the indoor air input end, and the heated air enters the room from the indoor air output end to heat the room, so that the purpose of heating the room is further achieved.
At night, the second valve 512 is closed, the first valve 511 is opened, outdoor air is introduced into the first heat dissipation layer 51, and due to evaporation of the absorbent in the liquid collection tank 12, the temperature of air entering the first heat dissipation layer 51 from the external air input end is reduced after passing through the liquid storage tank 1 by the cold energy generated in the evaporation process, and the cooled air is discharged outdoors from the external air output end, so that the influence of cooling on heat storage of the heat storage layer 4 is reduced, and the indoor warm environment is ensured and maintained.

The high-concentration mixed liquid 15 is heated to a higher temperature and boiling, and the low-concentration mixed liquid 14 outside the first communication pipeline 3 has a lower temperature and a higher density, while the gas-liquid mixture in the first communication pipeline 3 has a lower density, so that the gas-liquid mixture can reach the liquid spraying hole 32 along the first communication pipeline 3 according to the principle of the communicating vessel and is sprayed out from the liquid spraying hole 32. The gas and the liquid in the sprayed gas-liquid mixture start to separate, the sprayed high-concentration mixed liquid (the high-concentration absorbent is gasified when the absorbent in the high-concentration mixed liquid is completely gasified) is stored in the liquid storage tank 13, the gaseous absorbent rises to the liquid storage tank 1 at the upper part of the liquid storage tank 12, and the gaseous absorbent is condensed into liquid drops to be attached to the pipe wall at the upper part of the liquid storage tank 1 due to the fact that the upper part of the liquid storage tank 1 is close to the outside temperature, and the liquid drops flow into the liquid storage tank 12 along the pipe wall at the upper part of the liquid storage tank 1 along with the continuous increase of the liquid drops. The heat released during the condensation of the liquid heats the air entering the first heat dissipation layer 51 from the indoor air input end, and the heated air enters the room from the indoor air output end to heat the room.
At night, the second valve 512 is closed, the first valve 511 is opened, and the first heat dissipation layer 51 is filled with outdoor air. When no sunlight irradiates, the high-concentration mixed liquid in the liquid storage tank 13 (if the absorbent in the high-concentration mixed liquid is gasified completely, the high-concentration absorbent) starts to cool, because the solution in the liquid storage tank 13 has high concentration, the absorbent vapor can be absorbed, the concentration of the absorbent vapor in the liquid storage tank 1 is reduced, the absorbent in the liquid storage tank 12 is evaporated, the cold energy generated in the evaporation process reduces the temperature of the air entering the first heat dissipation layer 51 from the external air input end after passing through the liquid storage tank 1, and the cooled air is discharged outdoors from the external air output end, so that the influence of cooling on the heat storage of the heat storage layer 4 is reduced, and the indoor warm environment is ensured and maintained. The absorption process of absorbing the absorbent vapor in the liquid storage tank 13 emits heat to heat the water entering the second heat dissipation layer 52 from the water inlet, and the heated water is discharged through the water outlet for heating or domestic water. And the heat can be transferred to the room through the heat storage layer 4, so that the purpose of heating the room at night is achieved, and automatic radiation temperature regulation is realized. The concentration of the liquid in the liquid storage tank 13 becomes smaller after absorbing the absorbent, the volume becomes larger, and the liquid overflows into the low-concentration mixed liquid 14 in the liquid storage tank 1. Thus achieving the purpose of recycling.
