Description

Technical Field

[0001] This utility model relates to the field of ammonia preparation technology, specifically to a condensation device for an ammonia absorption refrigeration unit. Background Technology

[0002] The condenser in an ammonia absorption chiller is mainly responsible for condensing the high-temperature, high-pressure ammonia vapor generated in the generator into a liquid state, so that it can be evaporated and absorb heat in the evaporator to achieve the purpose of refrigeration.

[0003] However, traditional equipment uses air cooling, placing the plate heat exchanger outdoors in the atmosphere or indoors to achieve cooling. This method has limited functionality and low cooling efficiency. In view of this, we propose a condensation device installed in the liquid or refrigerant; external forced cooling can greatly improve the condensation effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a condensation device for ammonia absorption chiller units, which can greatly improve the condensation effect through external forced cooling.

[0005] This utility model provides a condensation device for an ammonia absorption chiller unit, comprising: a main housing, a plate heat exchanger, a hydraulic assembly, and a suction main component; the main housing is provided with an installation main chamber and a sliding chamber; the plate heat exchanger is installed in the main housing and located within the installation main chamber, one end of the plate heat exchanger extending outward and connected to one end of the suction main component; the other end of the plate heat exchanger extending outward is used to collect cooled ammonia water; the other end of the suction main component is connected to a high-pressure ammonia gas source; wherein the installation main chamber and the sliding chamber are connected; liquid nitrogen is sealed and injected into the installation main chamber, immersing the plate heat exchanger; the hydraulic assembly is slidably installed within the sliding chamber.

[0006] Furthermore, the main suction component includes a suction pipe and an on / off valve; one end of the suction pipe is connected to and communicates with the plate heat exchanger; the on / off valve is installed on the suction pipe. In practical applications, this design facilitates opening and closing, enabling real-time control during the ammonia preparation process.

[0007] Furthermore, it also includes a three-way solenoid directional valve. The first port of the three-way solenoid directional valve is connected to the high-pressure ammonia gas source; the second port of the three-way solenoid directional valve is connected to the suction main pipe; and the third port of the three-way solenoid directional valve is connected to the sliding chamber. In practical applications, the purpose of this design is to utilize the directional characteristics of the three-way solenoid directional valve, allowing the gas source to enter the suction main pipe or the sliding chamber in one direction only. When entering the suction main pipe, it can provide a gas source for condensation; while when entering the sliding chamber, the gas source, through pressure, drives the hydraulic components to move, thereby causing the liquid nitrogen in the main chamber to fluctuate and avoiding local temperature changes.

[0008] Furthermore, it also includes a main connecting pipe and branch pipes; one end of the main connecting pipe is connected to a high-pressure ammonia gas source; the other end of the main connecting pipe is installed at the first port of the three-way solenoid directional valve; there are two branch pipes, one end of each branch pipe is installed on the three-way solenoid directional valve, and is respectively located at the second and third ports of the three-way solenoid directional valve; the other end of one branch pipe is connected to the suction main pipe, and the other end of the other branch pipe is connected to the sliding chamber. In practical applications, the purpose of this design is to facilitate airflow.

[0009] Furthermore, both the main connecting pipe and the branch conduit are made of high-pressure tubing. In practical applications, this design uses rubber material that is resistant to high pressure and high temperature.

[0010] Furthermore, the hydraulic assembly includes a sliding piston and a spring; the sliding piston is slidably mounted within the sliding cavity and seals against the sliding cavity; one end of the spring abuts against the sliding piston; the other end of the spring is fixedly mounted on the sliding cavity. In practical applications, the purpose of this design is to facilitate the propulsion of liquid nitrogen, enabling the liquid nitrogen to fluctuate within the main mounting cavity. This effectively achieves heat dissipation and cooling of the plate heat exchanger, preventing heat from accumulating around the plate heat exchanger.

[0011] Furthermore, it also includes a magnetic attraction assembly, which comprises an electromagnetic ring. The sliding cavity has a mounting groove located on one side of the sliding piston, away from the opening of the sliding cavity. The electromagnetic ring is installed within the mounting groove. When the electromagnetic ring is powered by an external power source, it magnetically connects to the sliding piston and pushes the sliding piston to move within the sliding cavity. In practical applications, the purpose of this design is to further achieve effective driving of liquid nitrogen. By effectively magnetically attracting the sliding piston through the electromagnetic ring, its driving effect can be guaranteed.

[0012] As can be seen from the above technical solution, the beneficial effects of the condensing device for an ammonia absorption chiller provided by this utility model are as follows:

[0013] (1) In practical applications, liquid nitrogen or other refrigerant is injected into the main installation cavity of the main housing and the plate heat exchanger installed there is submerged to achieve effective heat dissipation.

[0014] (2) Moreover, the combination of the sliding cavity and the hydraulic components effectively promotes the fluctuation of the liquid flow in the main cavity, avoids the heat concentration of the plate heat exchanger, and makes it easier for it to dissipate heat effectively.

[0015] (3) Furthermore, by connecting the suction component with the high-pressure ammonia source, the continuous entry of ammonia is effectively ensured, thus ensuring the continuity of ammonia water after condensation. Attached Figure Description
