Precision air conditioning: why say high altitude area is not suitable for building data center

by:KEBO      2020-04-30
High altitude data equipment suitable for what kind of computer room precision air conditioning? Energy problem, it is a headache for data center operators. In order to reduce the energy consumption data center operation, people racking their brains to come up with various methods, such as in high latitude and high altitude climate relatively cold area to build the data center. But you know what? In high altitude area, because the atmospheric pressure is too low, actually build data center is not energy-saving. How does it work? First let's assume a scenario where the altitude is approximately equal to the level of the sea ( H = 0) There is a data center of Shanghai, according to the maximum return air temperature T1 = 38 ℃ design. If it is within the server needs to delta T = 20 ℃ temperature difference of heat dissipation, so we put the server is set to T0 = T1 - air inlet temperature Delta T = 18 ℃, can reach requirements. Now, we passed the peculiar strength, computer room precision air conditioning to the data center migration from Shanghai to Lhasa, Lhasa H = 3658 meters altitude, atmospheric pressure of 488 MMHG, 0 is a standard atmospheric pressure, 760 MMHG. 64 times) 。 In order to keep the same cooling ability, delta T = 20/0 at the moment. 64 = 31. 25℃; At this time, in order to keep out the wind temperature, server inlet temperature should be reduced to the T0 '= 38 - 31. 25 = 6. 75≈ 7 ℃, the temperature of the air conditioner set will be 6 & plusmn; 1 ℃, and at the time of the 6 ℃ air conditioner operation its refrigeration power particularly low. 【 Precision air conditioning 】 High altitude area, therefore, is not suitable for building data center. Even if has a data center, also is not suitable for use of high power density contour features computer servers, blade server.
