摘要
CO_(2)制冷系统在冷冻冷藏领域的推广应用对促进制冷剂替代、节能环保具有重要意义。本文介绍几种典型的CO_(2)制冷系统,并从冷凝(冷却)热量利用、系统能耗、系统初投资3个方面,将其与NH_(3)制冷系统、NH_(3)/CO_(2)复叠制冷系统进行对比分析,指出各CO_(2)制冷系统在冷冻冷藏领域内的适用场景,为CO_(2)制冷系统在冷冻冷藏领域的科学应用提供指导。
The promotion and application of CO_(2) refrigeration system in the field of freezing and cold storage is of great significance for promoting refrigerant substitution,energy-saving and environmental protection.Several typical CO_(2) refrigeration systems are introduced,and they are compared with the NH_(3) refrigeration system and NH_3/CO_(2) cascade refrigeration system from three aspects of condensing/cooling heat utilization,system energy consumption and system initial investment,so that the applicable scenarios of each CO_(2) refrigeration system in the field of freezing and cold storage are pointed out.It provides guidance for the scientific application of CO_(2) refrigeration system in the field of freezing and cold storage.
