Design considerations of power systems for the air conditioner used in telecommunication networks

Abstract

Air conditioning systems for telecommunication networks are importantthey maintain the temperature around the equipnent within the permitted range in order to guarantee stable performance. Telecommunication equipment with higher and wider band telecommunication services is forecasted to consume power several times more than present equipment, so the possibility of telerommrnication system failure originated from troubles in the air conditioning systems must be considered. Therefore, we calculate the reliability of air condi ti oning systems in high-power -consum i ng equ i pmen t taking into consideration time delay effect. We also consider a definite method to improve air conditioning system reliability. This method is effective in improving reliability of power-train by changing the switch in comparison with status information signal with a signal from the control equipnent.

A tool for calculating reliability of power supply for information and communication technology systems

“…Such facilities should be optimized for satisfying customer needs by quantitatively evaluating reliability, taking into account the characteristics of the region and device configuration for compensating power supply outages. Moreover, emphasis of power supply reliability has increased because of standards of the Tier Performance Standards [1] etc., and there have been many studies dealing with this field in past years [2][3]. The advantage of analyzing power reliability is that the best design considering initial cost, reliability, and customer demand becomes possible.…”
