Abstract

Disclosed are data center structures in which hot air (exhausted air from IT equipments) and cool air (for IT equipment intake air) are not mixed in. In data center, certain ratio of electric power is consumed for air conditioning for IT equipments. With the disclosed idea, the energy efficiency for the air conditioning becomes better, which leads to reduction of the electric power and the CO2 emission for the data center.

Data center of the structure that hot air and cold air are not mixed in .

Disclosed are data center structures in which hot air (exhausted air from IT equipments) and cool air (for IT equipment intake air) are not mixed in. In data center, certain ratio of electric power is consumed for air conditioning for IT equipments. With the disclosed idea, the energy efficiency for the air conditioning becomes better, which leads to reduction of the electric power and the CO2 emission for the data center.

Fig.1 shows an embodiment of the idea. In this case, the cool air from CRAC (Computer Room Air Conditioning) flows under floor and through the duct to the rack. And the exhausted hot air from the rack flows through the duct and the ceiling to the CRAC. With the embodiment, the cool air and the hot air are not mixed, which leads to energy efficient air conditioning.

Furthermore, if the duct is made of heat insulated material, the heat exchange between the air in the room and the cool (and/or hot) air becomes less.

Fig. 2 shows another embodiment of the idea. In this case, the air from the rack is directly exhausted out side of the room. So, in this case, the wall has open area for the exhausted air flow.

Considering the relocation of the rack, it may have tires at the bottom fo...
