In the past year, "ammonia safety" in the entire refrigeration equipment industry set off a hot word. As early as fifty or sixty years ago, ammonia is widely used as a refrigerant in the field of international industrial refrigeration in western France, and has been used so far. After decades of development, ammonia system technology has been very mature in theory, but in China due to the high cost of system automation installation is often reduced to manual or semi-automatic.
     However, since 2013, the continuous emergence of the media in the cold storage and casualties of the ammonia system, to a large extent, trapped the ammonia system in the development of large-scale refrigeration industry in china. Even some of the local regulatory authorities to promote the project to promote ammonia nitrogen adjustment, to the development of ammonia system caused a heavy blow.
     Compared with the fluorine system, the advantages of ammonia system are incomparable, the first is ammonia as the natural working substance, its GWP is 0, ODP is 0, is the most ideal and most environmentally friendly refrigerant in the large-scale refrigeration system. The second is that the ammonia thermal performance is good, the unit volume and the single machine refrigeration capacity are large, and the utility model has the advantages of high efficiency and energy saving in the large-scale refrigeration projects, especially the large-scale cold storage applications. Third, ammonia refrigerant price is much lower than freon, the initial investment is lower.
