中文摘要:
致冷的混合 TJR02 被开发,比较实验在原来为 R22 设计的一个 singlestage 蒸汽压缩制冷系统上被执行。试验性的结果证明没有修改原来的系统或变化润滑剂, TJR02 能直接在系统被使用。由用 TJR02 代替 R22,使率凉下来更快并且至少得到 20% 精力被节省。在标准试验台的实际察觉验证试验性的结果并且显示 TJR02 的采纳导致更大的效率和更宽的申请。并且冰箱温度越低,节省效果的精力将越明显。
英文摘要:
A refrigerant mixture TJR02 was developed and the comparison experiment was performed on a single- stage vapor compression refrigeration system originally designed for R22. Experimental results show that TJR02 can be directly used in the system without modifying the original system or changing lubricant. By replacing R22 with TJR02, cooling rate gets faster and at least 20% of energy is saved. The actual detection in the standard test-bed veri- fies the experimental results and indicates that the adoption of TJR02 leads to greater efficiency and wider application. And the lower the refrigeratory temperature is, the more obvious the energy saving effects will be.
