    • The invention relates to a waste heat recovery installation for a waste heat source (11), comprising an ORC (Organic-Rankine-Cycle) module that is mounted downstream of said waste heat source, the waste heat source (11) being connected to the heating device of the ORC module, and an expansion engine (4) coupled to a generator (5) for the steam expansion in the ORC module, said expansion engine comprising a magnetic bearing with an associated regulation device and a power supply unit via a DC intermediate circuit of a generator frequency converter. The aim of the invention is to optimize a waste heat recovery installation consisting of an ORC module that is mounted downstream of the waste heat source with respect to design and reliable operating behavior. According to the invention, a unit of expansion engine (4), generator (5) and frequency converter is proposed, which is cooled with refrigerant of the ORC circuit (1). Cool, liquid refrigerant is removed downstream of the feed pump (2) and is fed for cooling purposes to the unit consisting of expansion engine (4), generator (5) and frequency converter.
    • 本发明涉及一种用于废热源(11)由这些下游ORC(有机朗肯循环)中的一个的,其中,所述废热源(11)是在与ORC的加热装置进行通信的废热利用系统,以及与一个与发电机(5) 耦合膨胀机(4),用于在ORC,其包括具有相关联的控制装置,并通过频率发生器的DC中间电路的电源的磁性轴承蒸汽膨胀。 发明内容本发明的一个目的是优化从在结构和安全性能方面现有的废热利用系统的废热源ORC下游。 因此一个从ORC电路(1)的冷藏单元的制冷剂从膨胀机(4),发电机(5)和变频器根据本发明提出的。 冷的液体制冷剂由供给泵(2)和用于所述单元包括膨胀机(4),发电机(5)和供给的冷却至频率转换器汲取。
