To provide a cold recovery facility and a ship that can recover cold energy from two kinds of liquid fuels while efficiently vaporizing the liquid fuels.SOLUTION: A cold recovery facility comprises a first fuel tank 10 for storing a first fuel in a liquid state, a second fuel tank 20 for storing a second fuel in a liquid state with a higher liquefaction temperature than that of the first fuel, a first circuit 32 constituted so that a first medium is circulated, a first expansion turbine 34 on the first circuit, a first heat exchanger 36 for condensing the first medium, a pump 38 for increasing the pressure of the first medium, a second heat exchanger 40 for evaporating the first medium on the downstream side of the pump, and a third heat exchanger 42 on the downstream side of the second heat exchanger. The first heat exchanger is constituted so as to vaporize the first fuel in the liquid state from the first fuel tank by exchanging heat between the first fuel and the first medium. The third heat exchanger is constituted so as to vaporize the second fuel in the liquid state from the second fuel tank by exchanging heat between the second fuel and the first medium.SELECTED DRAWING: Figure 2
