PROBLEM TO BE SOLVED: To provide a refrigeration waste heat recovery system capable of achieving high efficiency by simple control while ensuring compactness by sharing a part of a Rankine cycle circuit and a refrigeration cycle circuit.SOLUTION: A refrigeration waste heat recovery system includes a Rankine cycle circuit and a refrigeration cycle circuit sharing a condensing portion composed of first and second condensers arranged in series, pressure detecting means for detecting a downstream-side fluid pressure of the condensing portion, flow channel determination means for determining an optimum flow channel in the condensing portion on the basis of the difference of a first threshold value corresponding to a pump of the Rankine cycle circuit and a second threshold value corresponding to a second evaporator of the refrigeration cycle circuit, and the detection value, and flow channel control means for controlling the flow channel to realize the optimum flow channel.SELECTED DRAWING: Figure 1 |
