Installation frigorifique à l'ammoniac - que savons-nous à son sujet?

Ammonia refrigeration plant - what do we know about it? Ammonia refrigeration plants are preferred when large and industrial refrigeration capacities are needed, because ammonia, as a refrigerant, is available, its market price is many times lower than the widely used agents, such as R449A, R452A, and it has no harmful impact on the environment. As a disadvantage, it can be stated that it is highly poisonous, an amount of 0.58 g/cubic meter, is deadly to humans, and special care is required when working with this agent, and it is necessary to ensure professional service from a specialist, which service the installation 24/7, i.e. under constant supervision by the on-duty teams. The ammonia refrigeration installation differs from the standard freon installation, with some differences in the refrigeration automation and equipment, associated with the properties of ammonia, to pass into different states necessary for the refrigeration process, the use of seamless steel pipes instead of copper, the oil in the installation is not absorbed in the ammonia, as is the case with widely used agents, and its independent removal and return to the compressor is required. We can summarize that ammonia refrigeration systems are less common in everyday life, as they are used mainly in large refrigeration installations and have higher cooling efficiency and operating costs.
