Using ammonia as a refrigerant offers these compelling advantages:
1. Ammonia stands out as the most economical refrigerant, only surpassed by air and water in terms of cost-efficiency.
2. Boasting a low standard boiling temperature with moderate pressure levels in both condenser and evaporator, ammonia ensures optimal performance.
3. It delivers substantial refrigeration capacity per unit volume, minimizing refrigerant circulation demands while boasting high thermal conductivity and latent heat of vaporization.
4. With minimal throttling losses, ammonia achieves superior operating efficiency.
5. Its low operating pressure translates to reduced demands on machinery and lower material costs for refrigeration systems.
6. The characteristic pungent odor of ammonia facilitates easy detection through smell, or with leak test paper and test drugs. Human olfactory senses can detect ammonia when air contains as little as 50mg/m3.
7. Ammonia is insoluble with mineral oil, allowing easy separation at low temperatures. Its lower density compared to oil aids in convenient oil return to the refrigeration system.
8. The thermodynamic and chemical properties of ammonia remain stable at both room and low temperatures.
9. With an Ozone Depletion Potential (ODP) of 0 and a Global Warming Potential (GWP) of 0, ammonia is environmentally benign.
The ammonia refrigerant charge is directly linked to potential risks. By optimizing system design, incorporating plate heat exchangers and dry shell evaporators, utilizing nitrogen direct expansion supply, and employing NH3/CO2 cascade refrigeration cycles, the refrigerant charge can be significantly minimized. Simplifying large ammonia systems with direct expansion supply and ammonia-miscible lubricating oil further reduces usage.
High-efficiency air coolers play a crucial role in reducing ammonia storage in cold rooms. The global trend underscores minimizing ammonia injection with efficient, energy-saving air coolers. Utilizing high-efficiency variable pitch stainless steel coil air coolers as evaporators achieves a dramatic 95% reduction in ammonia needed, compared to traditional systems.
Maximizing the design of ammonia refrigeration systems with automatic controls is essential for minimizing leaks and safeguarding operators.
Features:
1.Reliable system: Equipped with a renowned brand compressor, PLC controller, and an efficient oil separation system.
2. German Bitzer low-temperature screw compressor features high efficiency, extended lifespan, minimal vibration, and reduced noise levels.
3. The series includes globally recognized components and protection devices for compressor misdirection, overheating, overload, excessive discharging temperature, low oil levels, and high/low oil flow pressures.
4. The unit integrates an economizer to effectively enhance capacity for low-temperature operations.
Screw Compressor applications are extensive, spanning food refrigeration and freezing, aquaculture, commerce, petroleum, chemical and coal industries, textiles, pharmaceuticals, shipbuilding, defense, and scientific research, addressing comprehensive artificial refrigeration needs.
