B_(22)型、B_(23)型铁路机械冷藏车制冷机组工质替代方案浅析

Analysis of the Alternate Scheme for the Agent in Refrigerator Sets on B_(22) Type,B_(23) Type Railway Mechanical Refrigerator Cars

针对 CFC— 12禁用期限的临近 ,提出了一种 B2 2 型、B2 3型铁路机械冷藏车制冷机组工质的替代方案 ,并通过试验数据说明该方案有效可行。

For the forbidden limit for CFC-12 gets near, an alternate scheme for the agent in refri-gerator sets on B_ 22 type, B_ 23 type railway mechnical refrigerator cars is put forward, and the testing data show that the scheme is valid and feasible.
