A container system including cabinets, a main control unit connected to the cabinets and a heat dissipation zone is mentioned. The cabinet includes a plurality of serving zones each of which further includes a master server and at least one slave server. The heat dissipation zone is disposed at a side of the serving zone and coupled to the main control unit. Each slave server is coupled to the master server. The slave server includes at least one temperature sensor, and the temperature sensor is used for outputting temperature information to the master server when receiving the temperature demand. The master server collects the temperature information transmitted by each slave server. The master server forwards the temperature information to the main control unit. The main control unit drives the heat dissipation zone to dissipate heat of the serving zone according to the temperature information.
