It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The indirect evaporative cooling system is mainly based on natural cooling and supplemented by mechanical refrigeration, and comprises: the air conditioner mainly comprises an outdoor fan, an indoor fan, an air heat exchanger, a spraying evaporation device, a compressor and the like, and is mainly divided into three working modes, namely a natural cold source mode, a spraying mode and a mixed mode.
When the outdoor environment temperature is lower (if the temperature is not more than 18 ℃), the air conditioner works in a natural cold source mode, the spraying evaporation device and the compressor do not work at the moment, cold air outside the outdoor fan is sent into the air heat exchanger, return air with higher temperature in the data center is sent into the air heat exchanger by the indoor fan, the return air is directly cooled by outdoor low-temperature air, and the cooled air is sent back to the data center.
When the outdoor environment temperature is mild (for example, over 18 degrees), the air conditioner works in a spraying mode, the spraying evaporation device is operated at the moment, the compressor still does not work, the outdoor fan pre-cools outdoor air through the spraying evaporation device, then the outdoor air is sent into the air heat exchanger, and the indoor fan sends air with high temperature in the data center into the air heat exchanger to be cooled and then returns to the data center.
When the outdoor environment temperature is high (such as over 27 degrees) or the indoor temperature of the data center exceeds 23 degrees, the data center works in a mixed mode, the plurality of compressors, the spraying evaporation device and the plurality of compressors are all started to operate, the outdoor fan pre-cools outdoor air through the spraying evaporation device and the compressors, then the outdoor air is sent into the air heat exchanger, and the indoor fan sends the air with the high temperature of the data center into the air heat exchanger to be cooled and then returns to the data center.
In some scenarios, when the indirect evaporative cooling system operates in the three modes, the outdoor fan operates at a constant high rotation speed (e.g., 90% of the maximum rotation speed), and when the indirect evaporative cooling system operates in the mixed mode, the multiple sets of compressors are all started to operate, so that energy consumption is high, and energy waste is easily caused.
