[0021] Among them, the first heat exchange tube 8 and the second heat exchange tube 9 can maximize the heat conduction efficiency.

[0022] In this embodiment, the generator 5 stores a dilute lithium bromide solution, the absorber 2 stores a concentrated lithium bromide solution, the heater 7 stores a cold medium, and the refrigerator 4 stores a hot medium.

[0023] Among them, heating the lithium bromide solution can promote the evaporation of water. Heating will increase the kinetic energy of water molecules in the solution, making it easier to evaporate.

[0024] In this embodiment, a boiler water pipe is fixedly installed on the top of the generator 5 and connected to the second heat exchange tube 9 inside. The top of the generator 5 is connected to the top of the condenser 6 through a first pipe 10, and an expansion valve 11 is arranged between the bottom of the condenser 6 and the top of the evaporator 3.

[0025] The boiler water utilizes waste heat to heat the dilute lithium bromide solution in the generator 5 to generate high-temperature and high-pressure steam, which enters the condenser 6 through the first pipe 10, and the low-temperature liquid water is converted into mist-like low-temperature and low-pressure water through the expansion valve 11 and enters the evaporator 3.

[0026] In this embodiment, a second pipe 12 is installed between the top of the condenser 6 and the top of the heater 7, and the second pipe 12 is connected to the second heat exchange tube 9 in the condenser 6. A pair of third pipes 13 are installed between the side of the evaporator 3 and the side of the refrigerator 4, and the third pipe 13 is connected to the first heat exchange tube 8 in the evaporator 3.

[0027] Among them, high-temperature and high-pressure water vapor heats the cold medium of the heater 7 in the second heat exchange tube 9 in the condenser 6, and then turns into low-temperature liquid water. The misty low-temperature and low-pressure water absorbs the hot medium temperature of the refrigerator 4 in the first heat exchange tube 8 in the evaporator 3, and then turns into high-temperature water vapor.

[0028] In this embodiment, a fourth pipe 14 is installed on the side of the evaporator 3 and the side of the absorber 2, and a fifth pipe 15 is installed between the side of the absorber 2 and the side of the heater 7. The fifth pipe 15 is connected to the first heat exchange tube 8 in the absorber 2, and the middle part of the fifth pipe 15 is connected to the first water pump 17.

[0029] The high-temperature water vapor enters the absorber 2 through the fourth pipe 14, and the first water pump 17 circulates the cooling medium in the heater 7 in the absorber 2 and the condenser 6 to achieve continuous heating.

[0030] In this embodiment, a sixth pipe 16 is installed between the side of the absorber 2 and the side of the condenser 6, and the sixth pipe 16 is respectively connected to the first heat exchange tube 8 in the absorber 2 and the second heat exchange tube 9 in the condenser 6. A pair of seventh pipes 18 are fixedly connected between the generator 5 and the side of the absorber 2, and the middle part of the seventh pipe 18 is connected to the second water pump 19.

[0031] Among them, the high-temperature water vapor heats the cold medium of the heater 7 in the first heat exchange tube 8 in the absorber 2, and then turns into liquid water and dissolves in the concentrated lithium bromide solution. The second water pump 19 exchanges the gradually diluted lithium bromide solution in the absorber 2 with the gradually concentrated lithium bromide solution in the generator 5 through the seventh pipeline 18 to maintain a stable concentration.

[0032] In specific application, firstly, the device is installed and fixed through the base 1, and the refrigerator 4 and the heater 7 are connected to related equipment. Then, the high-temperature boiler water is connected to the second heat exchange tube 9 in the generator 5. The high-temperature boiler water heats the dilute lithium bromide solution in the generator 5 to generate high-temperature and high-pressure water vapor, which enters the condenser 6 through the first pipeline 10. The high-temperature and high-pressure water vapor heats the medium of the heater 7 in the second heat exchange tube 9 in the condenser 6, and then becomes low-temperature liquid water, which is converted into mist-like low-temperature and low-pressure water through the expansion valve 11 and enters the evaporator 3. The mist-like low-temperature and low-pressure water absorbs the medium temperature of the refrigerator 4 in the first heat exchange tube 8 in the evaporator 3. The temperature of the refrigerator 4 is continuously reduced by circulating through the third pipe 13. The mist-like low-temperature and low-pressure water is then changed into high-temperature water vapor and enters the absorber 2 through the fourth pipe 14. The high-temperature water vapor heats the medium of the heater 7 in the first heat exchange tube 8 in the absorber 2, and then becomes liquid water and dissolves in the lithium bromide concentrated solution. The medium is started, and the first water pump 17 drives the medium in the heater 7 to circulate in the absorber 2 and the condenser 6 to achieve continuous heating. The second water pump 19 is started to exchange the gradually diluted lithium bromide solution in the absorber 2 with the gradually concentrated lithium bromide solution in the generator 5 through the seventh pipe 18 to keep the concentration stable.
