The invention discloses a multi-target optimal control method for a novel ship cooling system, which comprises the following steps of: firstly, establishing a mathematical model of total radiation vibration power W and acoustic power level LW on the surface of a structure aiming at each mechanical device and a connecting pipeline of the novel ship cooling system, and then, establishing a mathematical model of total radiation vibration power W and acoustic power level LW on the basis of acoustic index measurement data of the novel ship cooling system under each steady-state working condition; the change trend of the optimal adjustable parameter set combination Xopt along with operation working condition parameters (such as thermal load and seawater flow) is obtained, then the rising and falling working condition process fusing acoustic indexes is considered, and the high-precision control logic of the vacuum degree (pressure) of the novel cooling system of the ship under the power rising and power falling work
