A container data center includes a container, servers, a monitoring device, a cooling system, and a controller. The container is divided into first regions and a second region which are separated from each other. The servers are received in the respective first regions. The monitoring device is for monitoring the servers and received in the second region. The cooling system includes a first generator for generating a first cool airflow, a second generator for generating a second cool airflow for the second region, an air pipe connecting the first regions and directing the first cool airflow to the first regions, and valves arranged in the air pipe. Each valve is positioned between each two adjacent first regions. The controller controls the first generator, the valves and the second generator.
