Ammonia Refrigerant Benefits
Qingdao Bingyan Refrigeration Equipment Co., Ltd. proudly unveils the numerous benefits of using ammonia as a refrigerant:
- Ammonia emerges as one of the most economical refrigerants, comparable to air and water in terms of cost-effectiveness.
- It features a low standard boiling temperature and operates under moderate pressure within the condenser and evaporator.
- Ammonia provides an exceptional refrigeration capacity per unit volume, necessitating less refrigerant circulation and ensuring superior thermal conductivity and latent heat of vaporization.
- It excels with minimal throttling loss and outstanding operational efficiency.
- Ammonia's low-pressure operation reduces machinery demands and cuts material costs for refrigeration systems.
- Its distinct pungent odor allows for easy leak detection, enhancing safety protocols.
- Ammonia is insoluble with mineral oil, simplifying the separation and return of oil within the refrigeration system.
- Its thermodynamic and chemical properties remain stable at both room and low temperatures, ensuring consistent performance.
- Ammonia stands out with zero Ozone Depletion Potential (ODP) and Global Warming Potential (GWP), making it an environmentally responsible choice.
