The invention relates to the technical field of industrial cooling, and discloses a cooling system for a film casting machine and a conversion method, the system comprises a water pool, a refrigerator, a negative pressure tower assembly, a pump valve assembly, a heat exchanger, a data acquisition module and a control module; the data acquisition module is used for acquiring outdoor temperature and a return water temperature value of the film casting machine; the control module is used for adjusting the pump valve assembly according to the outdoor temperature, the return water temperature and the set process temperature value, and controlling the negative pressure tower assembly and/or the refrigerating machine to operate. Through the arrangement of the negative pressure tower assembly, the operation time of a refrigerating machine is shortened, certain maintenance cost is saved, the control module flexibly adjusts the operation mode of the cooling system, and therefore suitable cooling temperatures can be ado
