摘要： The present invention relates to a system for heat refinement by utilizing waste heat in a conduct (6) comprising a first cycle (2), an evaporator (4) In which the circulating working fluid is evaporated to gas, a compressor (8) that compress the gas, a condenser (10) that condenses the gas to a condensate and releases heat to a passing heat carrier in the condenser, and an expansion valve (14) that expands the condensate and bring back the working fluid to the evaporator (4). The system further comprises a second cycle (16; 16a-d) is attached to the first cycle (2), a turbine (18), which supplies gas from the evaporator (4), whereby an expansion occurs, whereafter condensate is brought back to the evaporator (4).
