Natural cooling is an operating mode of the Data Center Cooling system. In the natural cooling mode, the compressor of the refrigeration unit will be partially or completely converted to bypass operation. Most systems that use the economizer mode convert the compressor section to bypass operation most of the time, thus saving some energy.
1. Direct fresh air is used as the bypass of air conditioner: the fresh air energy-saving cooling mode, when the outdoor air condition is within the set value range, the fan and the louver are used to extract a certain amount of cold air from the outdoor through the filter and directly enter the data center.
2. The hot-wheel heat exchanger is used as the bypass of the air-conditioner: the hot-wheel heat exchanger is used as the mode of air-conditioning bypass. When the outdoor air condition is within the set range, the outdoor cold air is blown into the hot-wheel heat exchanger by the fan. To keep the data center space in a relatively dry environment.
