对天然制冷工质CO2(R744)应用于低温大容量制冷工况下的循环形式进行了叙述,在给定工况下进行了循环性能计算,并与传统工质进行了比较。指出CO2跨临界循环与传统制冷剂循环相比有明显优势,适合应用于低温冷库工况。
The recirculation form of natural refrigerants CO2 (R744) used in low temperature and large capacity refrigeration is described. The cycle performance is calculated under given conditions and compared with the traditional refrigerants. It is pointed out that CO2 transcritical cycle has obvious advantages compared with traditional refrigerant cycle and suitable for low temperature cold storage.
