1. A cooling system comprising:
a control device comprising a plurality of valves, a plurality of pumps, and a plurality of pipelines, the plurality of valves and the plurality of pumps being set on the plurality of pipelines; and
an emergency cooling system comprising a chiller unit, a cooling tower, at least one cooling water storage tank, and a data center, wherein the cooling tower is coupled to the chiller unit, the at least one cooling water storage tank comprises a first cooling water storage tank and a second cooling water storage tank, each of the first cooling water storage tank and the second cooling water storage tank is coupled to the data center and the chiller unit through the plurality of pipelines; wherein:
an outlet of the data center and an inlet of the chiller unit is provided with a flow sensor for sensing a load of the data center, each of an inlet of the data center and the outlet of the data center is provided with a temperature sensor for sensing a temperature of the data center, each of the first cooling water storage tank and the second cooling storage tank is provided with a multipoint temperature sensor;
in a first condition, when temperatures of the data center are greater than a set temperature and a load of the data center is greater than a set load, the control device controls at least one of the plurality of valves to be opened to couple the chiller unit to the data center, and controls at least one of the plurality of pumps to be turned on to cause the chiller unit to supply cooling water to the data center;
in a second condition, when the temperature of the data center is less than the set temperature and the load of the data center is less than the set load, and temperatures of the at least one cooling water storage tank are greater than the set temperature, the control device controls some of the plurality of valves to be opened to couple the chiller unit to the first cooling water storage tank, the second cooling water storage tank, and the data center, and controls some of the plurality of pumps to be turned on to cause the chiller unit to supply cooling water to the data center, the first cooling water storage tank, and the second cooling water storage tank at the same time;
in a third condition, when the temperatures of the at least one cooling water storage tank are less than the set temperature, and the load of the data center is less than the set load, the control device controls some of the plurality of valves to be opened to couple the chiller unit to the first cooling water storage tank, the second cooling water storage tank, and the data center, controls at least one of the plurality of valves to be opened to couple the data center to the first cooling water storage tank and the second cooling water storage tank, and controls some of the plurality of pumps to be turned on to cause the first cooling water storage tank and the second cooling water storage tank to alternately supply cooling water to the data center and to cause the chiller unit to refill cooling water to either the first cooling water storage tank or the second cooling water storage tank while the other one of the first cooling water storage tank and the second cooling water storage tank provides cooling water to the data center.
