Safe Management of Ammonia Refrigeration Systems –May 2017 in Grantham Slide 3 PSM –The Tools 1. y This manual contains only general information on the physical properties, storage, and handling of ammonia containers and relevant equipment. Check the level of the liquid; if it is below the line, you have to charge refrigerant in it. Switch off the machine. xref to a substantially reduced ammonia charge for their cold storagefacilities. Wait about 10-15 minutes so that refrigerant settles down at liquid receiver. Condensation in the piping during construction. Ammonia Charging Hose For ammonia. %%EOF Allow the suction pressure gauge to fall to approximately 35kPa and then close the charging valve. h:w��C��'OILQ�9MW��}�Rٛ]���q�>��������sˏaAӝ��>W�WzT�$�rW-�������v. Ultra-reliable, safe and efficient operation of a packaged low charge ammonia system can be achieved through thorough testing at a wide range of conditions. Ammonia and its decomposition products are nutrients that make water systems eutrophic. 0 2.3This document does not address the 0000001480 00000 n Anhydrous ammonia is the liquid form of pure ammonia gas, technically water-free, and the substance used universally as an industrial refrigerant. 0000075754 00000 n Boost charging is not recommended except in exceptional circumstances e.g. Ammonia (R-717) has been a longtime, popular refrigerant choice in industrial facilities, such as cold storage warehouses, food processing plants, and chemical manufacturing plants. 0000002484 00000 n Ammonia system shutdown operations are another circumstance during which improper procedures can result in a release. Testing Facilities Testing is a fundamental requirement to researching and developing fully rated packaged low charge ammonia refrigeration systems that are ultra-reliable and efficient. Plans for testing and replacing safety equipment, such as monitors and alarm systems, detection equipment, radios, eye washes, respiratory and skin protection equipment, and first aid kits. Ammonia is a natural refrigerant that has been used for many years in a variety of applications due to its high thermal efficiency. o�}bJ��$9 �$��K 45 0 obj <>stream Steps to charge Ammonia refrigerant. • Installation is greatly simplified because the compact skid unit is factory build and tested • Plug & play design allows for simple & quick retrofits Ammonia is a gas with a distinctive pungent odour which can normally be detected by smell at concentrations as low as 5 parts per million (ppm). 0000002032 00000 n 1455 0 obj <> endobj 0000001187 00000 n Policies and procedures detailing how to safely operate and maintain the refrigeration system including the safe use, handling and disposal of ammonia. Subtract the refrigerant system charge from the amount of refrigerant in the cylinder and mark the level using a rubber band on the barrel. h�bbd``b`�� B H0ՁĄ�D03�X�������b``�J���� � �� Emergency preparedness also includes a need to address fires and other non-ammonia … A major ammonia spill is potentially disastrous, because liquid 0000000696 00000 n ��"��X�D���:��G��-�1���Xm 0O��xO{&�.
