Marine natural refrigerants are eco-friendly substances like ammonia, CO2, or hydrocarbons used in marine refrigeration systems. These systems are designed to minimize environmental impact while maintaining high efficiency in cooling applications aboard ships. They comply with strict international regulations to reduce greenhouse gas emissions in the maritime industry.
Marine Natural Refrigerants: Key specifications include ammonia (R717), carbon dioxide (R744), and hydrocarbons (propane R290, isobutane R600a). Grade: Industrial purity (99.5%+). Viscosity: Low (ammonia ~0.25 cP, CO2 ~0.07 cP). Buoyancy: Varies (ammonia lighter than air, CO2 denser). Material compatibility: Stainless steel, copper (for ammonia), carbon steel (CO2).
Refrigeration Systems: Size ranges from small (1-10 kW) to large (100+ kW). Operating pressures: Low (ammonia ~10-15 bar) to high (CO2 ~30-100 bar). Material: Stainless steel, aluminum, carbon steel. Efficiency: High (ammonia COP ~4-6, CO2 transcritical COP ~3-5). Temperature range: -50°C to +10°C (ammonia), -40°C to +30°C (CO2).
