| 摘要 |
The invention relates to a system for recuperating energy from a waste heat flow of an internal combustion engine (1), said system comprising a working fluid circuit (4) comprising at least one compressor (3) arranged in the waste heat flow, an expansion machine (6), a condenser (9) through which a coolant flows and a pump (5), the condenser (9) being connected to a coolant supply line (11) and a coolant discharge line (10). The invention also relates to a system for recuperating energy and to a method for operating the system in which the cooling requirement of the system is minimized. As a result, the coolant mass flow which comes into the condenser (9) via the coolant supply line (10) is variable. This can for example take place through a bypass which connects the coolant supply line (11) to the coolant discharge line (10) in accordance with the required cooling power of the condenser (9). |
