Patent ID: 8774980

Claim:
A cooling system to cool a plurality of servers of a container data center, the cooling system comprising: a first temperature sensor arranged in an external water source to sense a temperature of the external water source and output the sensed water temperature value; a pump to pump the water from the external water source; a first controller connected between the first temperature sensor and the pump to receive the sensed water temperature value, and compare the sensed water temperature value with a first predetermined temperature value, wherein if the sensed water temperature value is less than the first predetermined temperature value, the first controller controls the pump to pump the water from the external water source; a first filtering device connected to the pump to receive and filter the pumped water and output the filtered water to a cold water pipe of the container data center to cool the plurality of servers; a second temperature sensor to sense a temperature of water from a water outlet pipe of the container data center connected to the plurality of servers, and output a second temperature value; a first valve; a second valve; a second controller connected to the second temperature sensor, the first and second valves to receive the second temperature value, and compare the second temperature value with a second predetermined temperature value; and a second filtering device connected between a water application and the second valve, wherein if the second temperature value is greater than the second predetermined temperature value, the second controller turns off the first valve, and turns on the second valve to expel the water from the water outlet pipe to the second filtering device to filter the water expelled from the water outlet pipe and output the filtered water to the water application.
