The decision to use ammonia as a refrigerant presents an array of compelling benefits:
1. Ammonia stands out as the most cost-effective refrigerant, second only to air and water.
2. It features a low standard boiling temperature and maintains moderate pressure levels within condensers and evaporators.
3. With its large refrigeration capacity per unit volume, ammonia demands less refrigerant circulation per cooling capacity unit. It offers exceptional thermal conductivity and a high latent heat of vaporization.
4. The refrigerant boasts low throttling losses paired with high operational efficiency, enhancing overall performance.
5. Operating at a low pressure, it imposes minimal demands on machinery, reducing material costs for refrigeration systems.
6. Ammonia's distinct pungent odor allows for easy detection of leaks with the use of smell, test paper, and testing agents. Human olfactory senses can identify its presence when air contains just 50mg/m3 of ammonia.
7. It does not dissolve in mineral oil, easily separating at lower temperatures. Ammonia's lower density compared to oil facilitates oil return to the refrigeration system, as refrigeration oil typically settles beneath the ammonia liquid.
8. Its thermodynamic and chemical properties remain stable at both room and low temperatures, ensuring reliable performance.
9. With an Ozone Depletion Potential (ODP) of 0 and a Global Warming Potential (GWP) of 0, ammonia is an environmentally friendly refrigerant choice.
The quantity of ammonia filled in a system is a critical safety factor. Implementing strategic design measures—such as system optimization, adopting plate heat exchangers and dry shell evaporators, employing nitrogen direct expansion supply, and utilizing NH3/CO2 cascade refrigeration cycles—significantly minimizes refrigerant fill volume. Moreover, a streamlined ammonia system utilizing direct expansion supply and ammonia-compatible lubricating oil further reduces ammonia usage.
Incorporating high-efficiency air coolers into refrigeration systems minimizes ammonia storage in cold rooms. The international trend emphasizes reducing ammonia system injection and opting for energy-saving air coolers. Innovative high-efficiency, variable-pitch stainless steel coil air coolers serve as warehouse evaporators, decreasing traditional smooth discharge pipe ammonia injection by 95% at equivalent cooling capacities.
Ammonia refrigeration system design should prioritize automated controls to minimize leakage, safeguarding operator safety and enhancing system reliability.
