Product Description

Prime Advantages of Using Ammonia as a Refrigerant:
1. Ammonia stands out as the most economical refrigerant, second only to air and water.
2. It boasts a low standard boiling temperature, with moderate pressure levels in both the condenser and evaporator.
3. Ammonia offers exceptional refrigeration capacity per unit volume, demanding less refrigerant circulation per unit of cooling. Its high thermal conductivity and significant latent heat of vaporization ensure top-notch performance.
4. Experience minimal throttling loss and enjoy high operational efficiency.
5. Operates at low pressure, reducing requirements for machinery and cutting down material costs for refrigeration systems.
6. The distinct pungent odor of ammonia makes it easy to detect leaks using odor, test paper, or specific test drugs. Even at a concentration of 50mg/m3, its presence becomes noticeable to the human nose.
7. Ammonia remains insoluble with mineral oil, ensuring easy separation at low temperatures. Its lower density compared to oil allows refrigeration oil to sink below the ammonia liquid, facilitating convenient oil return to the refrigeration system.
8. It maintains stable thermodynamic and chemical properties at both room and low temperatures.
9. Boasts an Ozone Depletion Potential (ODP) of 0 and a Global Warming Potential (GWP) of 0, making it environmentally friendly.

The amount of ammonia in the system is a critical safety factor. By optimizing the system design and incorporating elements such as plate heat exchangers, dry shell evaporators, nitrogen direct expansion supply, and NH3/CO2 cascade refrigeration cycles, the refrigerant amount can be significantly reduced. Additionally, a simplified ammonia refrigeration system using direct expansion supply and ammonia-miscible lubricating oil considerably lowers the ammonia requirement due to its streamlined design.

Adopt high-efficiency air coolers to minimize the ammonia quantity stored in cold rooms. The global trend is to reduce ammonia injection in systems, opting for efficient, energy-saving air coolers. High-efficiency variable pitch stainless steel coil air coolers, serving as warehouse evaporators, require only 5% of the ammonia injection compared to traditional smooth pipe systems, leading to a 95% reduction.
Implementing automatic control in the ammonia refrigeration system design can significantly decrease leakage risks and ensure operator safety.

The Screw Compressor is extensively used across various industries, including food refrigeration and freezing, aquaculture, commercial sectors, petroleum, chemical industry, coal, textiles, pharmaceuticals, shipbuilding, defense, and scientific research, fulfilling diverse artificial refrigeration needs.
