Description

Marine air conditioner adopting R449A novel environment-friendly refrigerant Technical Field The invention relates to the technical field of marine air conditioners, in particular to a marine air conditioner adopting an R449A novel environment-friendly refrigerant. Background Existing marine heat exchangers (e.g., shell and tube condensers) typically rely on seawater or river water as a cooling medium for heat exchange. In practical application, because natural water sources generally contain calcium and magnesium ions, sediment and microorganisms, deposits such as scale, biological sticky mud and the like are easily formed on the inner wall of the heat exchange tube after long-term operation. The thermal resistance of such fouling is much higher than that of metal tube walls, which significantly deteriorates heat transfer efficiency, resulting in increased condensing pressure, reduced refrigeration capacity, and increased energy consumption. More critical is that the existing heat exchanger mostly adopts a fixed tube plate structure, and tens or hundreds of heat exchange tubes are expanded or welded on tube plates at two ends. With this integrated structure, once a certain heat exchange tube fails due to localized corrosion or severe fouling, it cannot be replaced alone or cleaned specifically while the system remains operational. The operators can only stop, empty the refrigerant, detach the end cover, and chemically clean the whole machine or replace the whole equipment. This not only results in high maintenance costs, but also forces the vessel to interrupt sailing operations, affecting operational economy and reliability.
