Description
Technical Field
The invention belongs to the technical field of environmental protection devices, and particularly relates to a cooling device and a cooling method utilizing underground raw water or a cold source of a water supply pipeline.
Background
At present, the data center adopts mechanical refrigeration with natural cooling, and the natural cooling can be realized only by the low temperature of the natural external environment, which basically belongs to 'eating by the sky'. The data center cooling operation mode is as follows: the refrigeration unit is operated in three modes of mechanical refrigeration, precooling and saving. Mechanical refrigeration mode: when the wet bulb temperature of the outdoor air is higher than T1The system operates in a mechanical refrigeration mode (the general set value is 15 ℃), the temperature of the water outlet of the cooling tower is between 19 and 38 ℃, and the normal operation of the refrigerator is ensured. A precooling mode: when the wet bulb temperature of the outdoor air is lower than T1And is higher than T2(the general set value is 4 ℃), and the control system automatically enters a precooling mode when the condition is continuously operated for 20 minutes. The temperature of the outlet water of the cooling tower is between 13.5 and 19 ℃. Saving mode: when the wet bulb temperature of the outdoor air is lower than T2(adjustable), which continues to run for 20 minutes (adjustable), the control system automatically enters the conservation mode. The temperature of the cooling tower effluent was controlled at 13.5 ℃. Exiting the saving mode: when the temperature of the outdoor air wet bulb is gradually higher than T2(tunable) below T1(adjustable) and the cooling tower fan is run at full speed, which is continued for 20 minutes (adjustable), the control system automatically enters the pre-cooling mode. Exiting the precooling mode: when the temperature of the outdoor air wet bulb is gradually higher than T1(adjustable), which continues to run for 20 minutes (adjustable), the control system automatically enters the mechanical cooling mode.
The wet bulb temperature of the outdoor air in most parts of south of the Yangtze river is less than 1/3 at the temperature of 15 ℃ and is still little less than 4 ℃; the utilization time of natural cooling is short; even under the condition of the mechanical refrigeration mode, the condensing pressure of the mechanical refrigeration is at a high level due to the high temperature of the external environment, and the refrigeration coefficient is at a low level, so that the energy consumption of the mechanical refrigeration is high.
