A study on cooling characteristics of ICT equipment and cooling performance in a data center

摘要

In the work reported here, we investigated the items listed below to identify factors that affect the ICT machine air intake temperature, focusing on the effects of machine cooling characteristics on air conditioning efficiency. 1)We created a machine cooling model that relates the temperatures in different parts, derived the parameters that affect the machine air intake temperature, and analyzed the factors that govern the machine cooling characteristics. 2)To understand the factors that affect the air intake temperature of rackmounted machines that generate high heat, we conducted experiments on the relation of the machine mounting method and the air intake temperature for various amounts of air conditioning in-flow. 3)We presented a method for determining the amount of air conditioning inflow that takes machine cooling characteristics into account, and evaluated the effect of machines cooling characteristics on air conditioning efficiency.
