DETAILED DESCRIPTION OF THE EMBODIMENTS

(5) Embodiments of the disclosure will be described below in detail. Examples of the embodiments are shown in the Figures, in which same or similar reference numbers refer to same or similar elements or elements having same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used for explaining the disclosure, not used for limiting the disclosure.

(6) It should be understood in the description of the disclosure that terms such as “upper”, “lower”, “front”, “back”, “left”, “right” etc. indicate direction or position relationships shown based on the drawings, and are only intended to facilitate the description of the disclosure and the simplification of the description rather than to indicate or imply that the indicated device or element must have a specific direction or constructed and operated in a specific direction, and therefore, shall not be understood as a limitation to the disclosure.

(7) In the description of the disclosure, the meaning of “several” refers to one or more; the meaning of “a plurality of” refers to two or more; greater than, less than and more than are understood as not including the number itself; and above, below, and within are understood as including the number itself. The terms such as “first” and “second” are only used for the purpose of differentiating technical features, rather than being understood to indicate or imply relative importance or implicitly indicate the number of indicated technical features or the order of the indicated technical features.

(8) In the description of the disclosure, the terms such as “arrangement”, “installation,” and “joint” shall be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the disclosure in combination with the specific contents of the technical solution.

(9) Referring to FIG. 1, there is shown a condensing system, including a generator 100, a rectifier 200, a condenser 300, an evaporator 400, an absorber 500 and a liquid storage tank 600, wherein the generator 100, the rectifier 200, the condenser 300, the evaporator 400, the absorber 500 and the liquid storage tank 600 are sequentially connected to form a loop. The gas outlet chamber 120 is communicated with the rectifier 200 by the lifting pipe 130, and a liquid conveying pipe 140 is arranged between the heating chamber 110 and the liquid storage tank 600. Ammonia sequentially flows from the generator 100, the rectifier 200, the condenser 300, the evaporator 400, the absorber 500 and the liquid storage tank 600 to realize ammonia circulation, and cool the outside air in the evaporator 400.

(10) Referring to FIG. 2, in the first embodiment, the generator 100 includes a heating chamber 110 and a gas outlet chamber 120. The gas outlet chamber 120 is connected with a lifting pipe 130, and has a width gradually reduced in a gas outlet direction. Concentrated ammonia water is heated in the generator 100, and ammonia is evaporated and enters the gas outlet chamber 120, and then enters the rectifier 200 along the gas outlet chamber 120. During the process that the ammonia enters the lifting pipe 130, a flowing channel gradually narrows to speed up the flow rate, which promotes the ammonia to enter the rectifier 200 and blocks some ammonia with backflow tendency, thus greatly reducing backflow and improving refrigeration efficiency. In this embodiment, the gas outlet chamber 120 is stepped, and steps on the gas outlet chamber 120 are provided with rounded corners. The steps with rounded corners can guide the flow of ammonia, thus promoting the ammonia to flow towards the lifting pipe 130. A right angle is formed at a joint between the heating chamber 110 and the liquid conveying pipe 140. The right angle can block the ammonia from flowing backwards, thus changing the path of the gas and preventing backflow.

(11) Referring to FIG. 3, in the second embodiment, the generator 100 includes a heating chamber 110 and a gas outlet chamber 120. The gas outlet chamber 120 is connected with a lifting pipe 130, and has a width gradually reduced in the gas outlet direction. Concentrated ammonia water is heated in the generator 100, and ammonia is evaporated and enters the gas outlet chamber 120, and then enters the rectifier 200 along the gas outlet chamber 120. During the process that the ammonia enters the lifting pipe 130, a flowing channel gradually narrows to speed up the flow rate, which promotes the ammonia to enter the rectifier 200 and blocks some ammonia with backflow tendency, thus greatly reducing backflow and improving refrigeration efficiency. In this embodiment, an inner wall of the gas outlet chamber 120 is of a concave arc shape. The inner wall of a concave arc shape can guide the flow of ammonia, thus promoting ammonia to flow towards the lifting pipe 130. A right angle is formed at a joint between the heating chamber 110 and the liquid conveying pipe 140. The right angle can block the ammonia from flowing backwards, thus changing the path of the gas and preventing backflow.

(12) In the above two embodiments, referring to FIGS. 2 and 3, the lifting pipe 130 is externally sheathed with a sleeve 150 which is communicated with the absorber 500. After evaporating ammonia, the remaining dilute ammonia water reenters the absorber 500 and then enters the liquid storage tank 6000 along with the ammonia in the absorber 500.

(13) Embodiments of the disclosure are described above in detail with reference to the accompanying drawings. However, the disclosure is not limited to the above embodiments. Within the scope of the knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the disclosure.
