[0023] Referring to Figure 1 , the condensation system includes a generator 100, a rectifier 200, a condenser 300, an evaporator 400, an absorber 500 and a liquid storage tank 600. The generator 100, the rectifier 200, the condenser 300, the evaporator 400, the absorber 500 and the liquid storage tank 600 are connected in sequence to form a loop. The gas outlet cavity 120 and the rectifier 200 are connected through the riser 130. A liquid delivery pipe 140 is provided between the heating cavity 110 and the liquid storage tank 600. Ammonia flows through the generator 100, the rectifier 200, the condenser 300, the evaporator 400, the absorber 500 and the liquid storage tank 600 in sequence to realize the ammonia cycle, and refrigerates the external air in the evaporator 400.

[0024] And among them, referring to Figure 2, Example 1, the generator 100 includes a heating chamber 110 and an air outlet chamber 120. The air outlet chamber 120 is connected to a riser pipe 130. The width of the air outlet chamber 120 gradually decreases along the air outlet direction. Concentrated ammonia water is heated in the generator 100, ammonia gas evaporates and enters the air outlet chamber 120, and enters the rectifier 200 along the air outlet chamber 120. During the process of ammonia gas entering the riser pipe 130, the flow channel gradually narrows, increasing the flow rate, promoting the entry of ammonia gas into the rectifier 200 and at the same time hindering some of the ammonia gas with a tendency to flow backward, greatly reducing the backflow and improving the refrigeration efficiency. In this embodiment, the air outlet chamber 120 is in a stepped shape, and the steps on the air outlet chamber 120 are provided with rounded corners. The stepped rounded corners can guide the ammonia gas and promote the flow of ammonia gas in the direction of the riser pipe 130. The connection between the heating chamber 110 and the infusion pipe 140 is at a right angle. The right angle can hinder the backward flow of ammonia gas, change the path of the gas, and prevent backflow.

[0025] Among them, referring to Figure 3 , Example 2, the generator 100 includes a heating chamber 110 and an air outlet chamber 120. The air outlet chamber 120 is connected to a riser pipe 130. The width of the air outlet chamber 120 gradually decreases along the air outlet direction. Concentrated ammonia water is heated in the generator 100, ammonia gas evaporates and enters the air outlet chamber 120, and enters the rectifier 200 along the air outlet chamber 120. During the process of ammonia gas entering the riser pipe 130, the flow channel gradually narrows, increasing the flow rate, promoting the entry of ammonia gas into the rectifier 200 and at the same time hindering some of the ammonia gas with a tendency to flow backward, greatly reducing the backflow and improving the refrigeration efficiency. In this embodiment, the inner wall of the air outlet chamber 120 is in a concave arc shape. The inner side wall of the concave arc shape can guide the ammonia gas and promote the flow of ammonia gas in the direction of the riser pipe 130. The connection between the heating chamber 110 and the infusion pipe 140 is at a right angle. The right angle can hinder the backward flow of ammonia gas, change the path of the gas, and prevent backflow.

[0026] In the above two embodiments, referring to Figure 2 and Figure 3 , a sleeve 150 is sleeved outside the riser pipe 130, and the sleeve 150 is connected to the absorber 500. The remaining dilute ammonia water after evaporating ammonia gas re-enters the absorber 500 and enters the liquid storage tank 600 along with the ammonia in the absorber 500.

[0027] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
