The invention discloses a ventilation system of a ship cargo hold. The ventilation system comprises N cargo hold fans, a frequency converter, N cargo hold temperature sensors, an ambient temperature sensor and a central controller, wherein the central controller is respectively connected with N cargo hold temperature sensors, the frequency converter and the ambient temperature sensors; N cargo hold fans are connected with the frequency converter, one cargo hold fan corresponds to one cargo hold temperature sensor and is arranged in the same ship cargo hold; the central controller is used for calculating a needed ventilation quantity of each ship cargo hold according to the temperature of N cargo holds, ambient temperature and cargo information of each cargo hold and transmitting a control order to the frequency converter according to the needed ventilation quantity; the frequency converter adjusts the speed of the N cargo hold fans according to the control order so as to adjust the ventilation quantity of each ship cargo hold. By adopting the embodiments, on the basis of guaranteeing the safety of the cargos in the cargo hold, the energy consumption of the ventilation system is reduced, and the oil consumption of ships is reduced.
