With the advent of the era of big data, the power density of the IT equipment in the computer room server is increasing day by day. It has the characteristics of high energy consumption and high heat, and the future development direction is to build a green data machine room. The evaporation and cooling technology not only has the functions of energy saving, economy, environmental protection, but also has the functions of humidification and purification, so it has broad application prospects in communications rooms, base stations, and data centers.

Only using evaporation and cooling technology in dry areas can meet the environmental requirements of the computer room. However, the combination of evaporation and cooling with mechanical refrigeration in some medium humidity areas and humidity areas can meet the environmental requirements of the computer room. For example, a communication machine room in Xinjiang China Telecom and a communication base station in Xinjiang use evaporated air -conditioned air conditioning to cool down for the computer room; a certain communication machine room in Guangdong China Mobile, Hebei Railong’s communications machine room, and a communication machine room in Fuzhou China Unicom uses evaporation and cooling machine. The mechanical refrigeration linkage control is the cooling of the machine room; a communication machine room in Xi’an uses evaporation cooling and mechanical refrigeration combined air -conditioning system for the machine room to cool down. Foreign data centers, for example, a data center in the United States also uses evaporative air -conditioners. These engineering instances have achieved good energy conservation and cooling effects.

The communication machine room/base station and data center can also use dew -point indirect evaporation coolers. For example, a foreign data center uses an dew point indirect evaporation cooler. Insufficient temperature drops, and the use of energy steps.

The application prospects of the water side evaporation and cooling in the communication machine room/base station, and data center are also very broad, which can make the cooling tower directly free to cool (free cooling) or use evaporate cooling and cold water units to provide high temperature and cold water. Side evaporate and cooling, it has a strong ability to take away the calories, and it can make full use of the natural cold source. Therefore, evaporation and cooling technology has broad application prospects in communication machine rooms/base stations and data centers.
