The invention provides a frequency converter cooling system integration device and a cooling control method, and belongs to the technical field of refrigeration equipment, the integration device is provided with a first space and a second space which are isolated from each other, a frequency converter, a first heat exchange assembly and a second heat exchange assembly are arranged in the second space, and the frequency converter comprises a power module; the first heat exchange assembly is placed on the lower surface of the power module and used for cooling the power module, and the second heat exchange assembly is used for cooling the interior of the second space. And cooling the integrated frequency converter by adopting at least one of a first control method, a second control method, a third control method and a fourth control method. The possibility of condensation inside and outside the frequency converter cabinet is reduced, and meanwhile the temperature uniformity of the heat exchange assembly is impro
