The present invention provides a plant factory system that uses vaporized cold heat that can effectively use vaporized cold heat of LNG in a plant factory. A plant factory system that uses LNG vaporization cold heat, a vaporizer 1 for exchanging heat between LNG and a first intermediate medium M1 to vaporize LNG, and the first intermediate medium M1 and the first intermediate medium M1. A first heat exchanger H1 that exchanges heat with the second intermediate medium M2, a second heat exchanger H2 that exchanges heat between the second intermediate medium M2 and the air in the plant factory 10, and the second And a fan 6 for blowing the air heat-exchanged by the heat exchanger H2.
