Using ammonia as a refrigerant has the following advantages:
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 amount of ammonia filling in the system is closely related to the possibility of danger. In system design, measures such as optimizing the system, using plate heat exchangers and dry shell evaporators, using nitrogen direct expansion supply, and using NH3/CO2 cascade refrigeration cycles can significantly reduce the amount of refrigerant filling. In addition, a large ammonia refrigeration system simplified by using direct expansion supply and lubricating oil that is miscible with ammonia will greatly reduce the amount of ammonia used due to system simplification.
Using high-efficiency air coolers to reduce the amount of ammonia stored in the cold room. The current international trend in the development of ammonia systems is to reduce the amount of ammonia injected into the system and choose efficient and energy-saving air coolers. The high-efficiency variable pitch stainless steel coil air cooler can be used as the evaporator in the warehouse, which only accounts for 5% of the traditional smooth discharge pipe ammonia injection amount at the same cooling capacity, reducing the ammonia injection amount by 95%.
The design of ammonia refrigeration system should adopt automatic control as much as possible to reduce leakage and ensure the safety of operators.
