Ammonia is a colorless gas with a very strong smell that can be extremely dangerous. It’s used in many commercial cooling systems as a refrigerant. However when not properly controlled it can lead to contaminate food and air space.

Ammonia rooms are a separate building from the main factory that ventilates and stores the ammonia based cooling. Ammonia refrigeration systems contain a 3 stage vapor compression cycle: Compression, condensation, and evaporation. Ammonia is received through the intake ventilation. The compressor is the heart of the system creating the flow of components. As the compressor receives the gas at a low temperature, while it is being compressed, pressure builds up and releases it at a high temperature.  Moving into the condenser which is responsible for heat transfer, the components separate the heat from the liquid using different types of condensers. They are water cooled, air cooled, evaporative condenser and static condenser. The evaporator causes the refrigerant to evaporate as liquid vapor and low temperatures absorb heat. To gage the ammonia levels these systems use a 24 hour monitoring system. A suitable fan must ventilate the machine room and storage rooms. All ventilating fans require switches both inside and outside the machine, and provide 15 air changes an hour. Ventilation fans are used to push out warm air and bring in clean air.

Without these systems there would be a high risk of the chance of explosions, food contamination and harmful effects on human consumption. Here at B.A.Romines Sheet Metal, we’re ready to provide your ammonia refrigeration system installation needs.  We meet environmental standards when building and constructing Ammonia rooms to meet the OSHA standards.
