Product Description: Ammonia Refrigerant by Qingdao Bingyan Refrigeration Equipment Co., Ltd.
Using Ammonia as a Refrigerant Offers Numerous Advantages:
- Ammonia stands out as one of the most cost-effective refrigerants, surpassed only by air and water.
- It features a low standard boiling temperature and maintains moderate pressure in both the condenser and evaporator.
- Ammonia delivers a substantial refrigeration capacity per unit volume, reducing the need for refrigerant circulation. Its high thermal conductivity and latent heat of vaporization enhance efficiency.
- It excels with low throttling loss and superior operating efficiency.
- Ammonia's low operating pressure minimizes machine requirements and material costs for refrigeration systems.
- It possesses a distinct pungent odor, simplifying leak detection.
- Ammonia's insolubility with mineral oil allows easy separation and oil return within the refrigeration system.
- Its thermodynamic and chemical properties remain stable at both room and low temperatures.
- Ammonia boasts an Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) of zero, making it an eco-friendly choice.
