摘要
理论计算并比较NH_(3)/CO_(2)载冷系统和R507A桶泵系统的性能,旨在为NH_(3)/CO_(2)载冷系统合理应用提供参考。计算结果表明,在冻结物冷藏间工况下,NH_(3)/CO_(2)载冷系统COP比R507A桶泵系统高约1.5%;在冷却物冷藏间工况下,NH_(3)/CO_(2)载冷系统COP比R507A桶泵系统高约11%。
The theoretical calculation and comparison are conducted between NH_(3)/CO_(2) secondary refrigerant system and R507A pump supply system,aiming at providing reasonable reference for the application of NH_(3)/CO_(2) secondary refrigerant system.It is shown that in application of frozen cold storage room,the COP of NH_(3)/CO_(2) secondary refrigerant system is about 1.5%higher than R507A pump supply system;in application of chilled cold storage room,the COP of NH_(3)/CO_(2) secondary refrigerant system is about 11%higherthanR507A pumpsupplysystem.
