Air Conditioning System for Computer Room Racks {Air-Conditioning System for Rack of Computer Room}

The present invention relates to an air conditioner for a computer room rack, and more particularly, to an air conditioner for a computer room rack that is capable of performing constant temperature and humidity and cooling and is easy to install.

In general, governments, corporations, financial institutions, schools, research institutes, etc. operate a computer room where communication equipment (network equipment, servers, communication exchangers, etc.) and large-capacity computers and servers are installed.

Electronic components used in computers or communication equipment installed in the computer room are not smoothly operated at high temperatures, and a lot of heat is generated during operation, and thus a device for cooling them is required.

Furthermore, since most computers or communication equipments are often installed in a rack, it is important to keep the temperature inside the computer room constant, but it is more important to keep the temperature inside the rack constant.

In the case of electronic components or circuits, there is a risk of a short circuit when there is a lot of moisture, and when there is too little moisture, there is a high possibility that problems such as fire or damage to electronic components due to static electricity generation, sparks, and the like are high.

Therefore, an air conditioner for cooling and constant temperature and humidity is installed in the computer room and the rack, and the Republic of Korea Patent Publication Nos. 10-0478755, 10-0997045, 10-1103394, and 10-2011-0009848 Nos. 10-2010-0013312, 10-2011-0095580, 10-2012-0000224, and the like disclose technologies for various air conditioners installed in computer rooms and racks.

However, the conventional computer room and rack air conditioners have a problem that hot air and cold air are mixed with each other in the middle to consume a lot of energy in cooling and maintaining the temperature.

In addition, the conventional computer room and the rack air conditioner are installed in a fixed state, and thus, there is a problem in that it is complicated and time consuming to separate and reinstall for repair and maintenance.

An object of the present invention is to solve the above problems, it is possible to increase the cooling efficiency by separating and inducing the flow of hot air and cold air, it is possible to perform the humidity function without installing a separate humidifier, It is to provide an air conditioner for a computer room rack that is easy to maintain and install because it can be mounted and separated by a sliding method.
