Abstract: A container data center includes a temperature control system to monitor a temperature of the container data center. The temperature control system includes a temperature sensor to sense the temperature of the container data center. The temperature control alarm system determines whether the sensed temperature is greater than first and second predetermined temperatures. The second predetermined temperature is greater than the first predetermined temperature. If the sensed temperature is greater than the first predetermined temperature, a cooling device is turned on to cool the container data center. If the sensed temperature is also greater than the second predetermined temperature, an alarm device is started and an alarm message is transmitted to a monitor center.
