Recently, the Ministry of Industry and Information Technology issued the "Recommended Catalogue of Energy Saving and carbon Reduction Technology and Equipment in the Field of National Industry and Information Technology (2024 edition)", and the indirect evaporation cooling technology and indirect evaporation cooling cooling technology independently developed by Aolan (Fujian) Industrial Co., Ltd. were successfully selected into the recommended catalogue of energy saving and carbon reduction technology and equipment. It has become a key technology for ventilation and cooling of data centers and data rooms.

Indirect evaporative cooling technology for making cold water

Applications: Data center

Technical principle: The internal cooling indirect evaporative cooler is the core of the technology, and the heat absorption effect of water evaporation is used to produce cold water through heat exchange. There is no direct physical contact between the evaporation process and the cold water, and no mechanical refrigeration is involved. The outlet temperature of the cold water can be 2~3℃ lower than the ambient air wet bulb temperature. This technology is suitable for providing an efficient ventilation and cooling solution for data centers

Indirect evaporative cooling to produce cold air technology

Applications: : Air conditioning system in communication room

Technical principle: The technology uses an indirect evaporative cooling heat exchanger with high efficiency and low resistance to cool the indoor high temperature return air through the working air flow in the wet channel. The technology has three operating modes. When the unit runs in dry mode, the indoor return air and outdoor fresh air exchange heat inside the core body to achieve cooling. When the unit is running in wet mode, the indoor return air is exchanged through the dry channel of the core and the outdoor fresh air cooled by evaporation cooling on the wet channel of the indirect evaporative cooling core to achieve cooling. When the unit switches to the mixed mode, the indoor return air is exchanged through the dry channel of the core and the outdoor fresh air cooled by evaporative cooling on the wet channel of the indirect evaporative cooling core, and further cooled through the evaporator of the mechanical refrigeration system.

With the vision of becoming the world's leading brand in the field of air treatment, Aolan (Fujian) Industrial Co., Ltd. is a national high-tech enterprise focusing on the research and development, production, sales and service of air treatment products.
