Well, next to its numerous environmental benefits it also involves several risks. ... between the Machinery Room Design, System Design, and Testing and Charging sections. If ammonia gas escapes from a refrigeration system or a storage container in dry air, it will tend to rise to high areas or ceilings. AMONUM chillers can also be set up in a machine room. This is why ammonia is used in refrigeration systems. Refrigeration System And Cold Rooms. Why is ammonia as a natural refrigerant not far more widely used? Ferdinand Carré's ice-making device. This does not include a cold-storage room in which evaporators are located, a In ammonia-based refrigeration systems, the transmitters of a gas measurement system are normally installed in the compressor room and near the valve stations, for example to check the pipe ends. Exposure to 300 parts per million (ppm) is immediately dangerous to life and health. Ammonia gas is colourless and has a suffocating, pungent, penetrating odour. Photograph: shows a modern ammonia refrigeration plant room - courtesy of Nestlé UK. Industrial refrigeration safety is very important. For this reason, ammonia is classified as very toxic to aquatic life. With a housing of protection class IP54, they can be set up indoors and outdoors.
