(ii) Aboveground uninsulated containers may be charged 87.5 percent by volume provided the temperature of the anhydrous ammonia being charged is determined to be not lower than 30 °F. A major ammonia spill is potentially disastrous, because liquid While ammonia leaks are rare when following proper procedures, they can still occur. %%EOF Allow the suction pressure gauge to fall to approximately 35kPa and then close the charging valve. Complex chemical reactions between oil, oxygen and ammonia. Open the liquid receiver outlet valve and the plant is then ready for normal operation. The ratio of liquid to gas is 1 to 800, which means that 1 litre of liquid ammonia expands to form 800 litres of gas. Since ammonia is environmentally benign, having zero (GWP) and zero (ODP) characteristics, ammonia is emerging as one of … Ammonia is highly toxic to fish. ammonia. develop, define, and/or review operating procedures for ammonia refrigerating systems. <<6A9FC5C92F5FE64F93ECDA9015A48D2A>]>> h��Sߋ1�W�X�$�_8��l��{�iЀ�����w&����E�X�lfg&3߷_F�A�2� jņ%ñ�@W� ������[�o�n�� �?���hW��ø���ršJܥ.��x� h2�u;l�n��j��8y,�q^'䆊�})��q�D0�����i�c�ϺnFJ��)&).r�%>����ŴM�o�U��ܥR�Q������#x���{@���u��yoۏ���[�Y��u�O��o��*�_؞;0)]HM�9��+1=� �(�N(:��EP2�� Higher concentrations are easily detected.

Training 5. Operating procedures 4. %%EOF Now with increased regulatory activity on fluorocarbon refrigerants (i.e., HCFCs and HFCs), even more interest has grown with ammonia as a refrigerant.. Management of change 8. 1. Ammonia is a natural refrigerant that has been used for many years in a variety of applications due to its high thermal efficiency. Set the barrel on the charging cylinder to align with the refrigerant pressure. The main use of refrigeration plants on ships is to keep cargo and food provisions at low temperature to prevent them from spoiling. 2.3This document does not address the When disconnecting the ammonia cylinder and hose from the charging valve, first slacken the flange bolts to allow the ammonia in the hose to escape or pump down. 1. 0000008246 00000 n Charging Procedure with Boost Chargers A.
