Heating medium system capable of being debugged in split-range mode and debugging method

The invention discloses a heating medium system capable of being debugged in a split-range mode and a debugging method. The heating medium system comprises a filling pump (B), an expansion tank (A), a filling pipeline, an expansion pipeline, a first heating medium furnace (C), a second heating medium furnace (E), a first circulating pump (D), a second circulating pump (F), a first oil-gas separator (G) and a second oil-gas separator (H). Under the condition that normal operation of a heating medium system of an existing heat utilization unit is not affected, an independent expansion tank does not need to be provided for the newly-added heat utilization unit, and heating medium filling and heating medium system debugging of the newly-added heating medium system are completed through the expansion tank of the original heating medium system. 一种可分程调试的热媒系统和调试方法，包括：充填泵(B)、膨胀罐(A)、充填管线、膨胀管线、第一热媒炉(C)、第二热媒炉(E)、第一循环泵(D)、第二循环泵(F)、第一油气分离器(G)和第二油气分离器(H)。本发明在既不影响现有用热单元热媒系统正常运行的情况下，又无需为新增用热单元提供独立的膨胀罐，利用原热媒系统膨胀罐完成对新增热媒系统的热媒加注
