Various ice production systems and temperature controlled warehouses (TCW) use the same process on a larger scale. Precautions should be taken to protect employees, surrounding communities, and the environment. The ammonia refrigeration cycle begins with bringing in warm air, stripping the heat out of it, and then sending the cooled air back where it needs to be. The purity of the anhydrous ammonia is vital to the properties that make it a good refrigerant. Beaverton, OR
Air Pollution May Contribute to Alzheimer’s and Dementia Risk. The ammonia gas condenses into ammonia liquid (dark blue) at high pressure. Refrigeration systems use basic physics to transfer heat energy out of one area and into another, leaving the first area cooler than it was before as in the cold store systems. The purity of the anhydrous ammonia is vital to the properties that make it a good refrigerant.

OSHA considers anhydrous ammonia to be “immediately dangerous to life and health” at a concentration of 300 parts per million (ppm), or 0.03%. While some refrigerants have no noticeable smell, allowing small leaks to go unnoticed, that’s not the case with ammonia. We’ll start at the basics and work our way up covering some typical systems for single-stage, two-st a ge and cascade systems to help you learn the basics of industrial refrigeration. Most of ammonia’s potential for harm relies on there being too much of it in one place, not on its being leaked and scattered into the environment. This online course covers all maintenance aspects of using ammonia as a refrigerant. In refrigeration systems, ammonia is in either a liquid or vapor state, or a mixture of the two. The physical properties of the refrigerant determine the pressure and temperature ranges of the system, along with the rate of cycling required for a given cooling effect. Ammonia is corrosive to the skin, eyes, and lungs, and even a brief exposure can result in severe chemical burns. National Lab Director Expects to Continue Working on Next Wave of Reactors.
