1. Ammonia is the cheapest refrigerant besides air and water.
2. The standard boiling temperature is low, and the pressure is moderate in the condenser and evaporator.
3. A large refrigeration capacity per unit volume requires less refrigerant circulation per unit cooling capacity, high thermal conductivity, and high latent heat of vaporization.
4. Low throttling loss and high operating efficiency.
5. Low operating pressure, low requirements for machines, and low material cost for refrigeration systems.
6. There is a pungent odor, which is easily detected by the odor, leak test paper, and test drug in case of leakage. When the air contains 50mg/m3 of ammonia, the human sense of smell can distinguish it.
7. Insoluble with mineral oil, easily separated from oil at low temperatures, ammonia has a lower density than oil, and refrigeration oil often sinks below the ammonia liquid, making it convenient to return oil to the refrigeration system.
8. Thermodynamic and chemical properties are stable at room temperature and low temperature.
9. ODP=0, GWP=0.


The design of ammonia refrigeration system should adopt automatic control as much as possible to reduce leakage and ensure the safety of operators.
