Constant temperature CRAC control algorithm

Abstract

A method of cooling including providing a fluid flow at a predetermined temperature, and adjusting at least one cooling parameter of at least one cooling device to maintain the predetermined temperature of the fluid flow when a desired mass flow of the fluid flow changes. A cooling system and further embodiments are also disclosed.

Description

BACKGROUND OF INVENTION[0001]1. Field of Invention[0002]Embodiments of the invention relate generally to devices and methods for cooling electronic equipment. Specifically, aspects of the invention relate to methods of cooling electronic equipment by providing a relatively constant temperature air flow to the equipment.[0003]2. Discussion of Related Art[0004]Heat produced by electronic equipment can have adverse effects on the performance, reliability and useful life of the equipment. Over the years, as electronic equipment becomes faster, smaller, and more power consuming, such equipment also produces more heat, making control of heat more critical to reliable operation.[0005]A typical environment where heat control may be critical includes a data center containing racks of electronic equipment, such as servers and CPUs. As demand for processing power has increased, data centers have increased in size so that a typical data center may now contain hundreds of such racks. Furthermore...

AI Technical Summary

Benefits of technology

[0012]In some embodiments, the method, further comprises monitoring at least one cooling condition, and adjusting the at least one cooling parameter based on a change in the at least one cooling condition to maintain the desired mass flow of the fluid flow and the predetermined temperature. In some embodiments, the at least one cooling condition includes at least one of a current mass flow of fluid to current cooling capacity ratio, a pressure loss, a temperature, and a temperature change. In some embodiments, adjusting the at least one cooling parameter based on the change in the at least one cooling condition includes adjusting the at least one cooling parameter to avoid spikes in the mass flow of the fluid and a current output temperature of the fluid.

Problems solved by technology

Heat produced by electronic equipment can have adverse effects on the performance, reliability and useful life of the equipment.

Over the years, as electronic equipment becomes faster, smaller, and more power consuming, such equipment also produces more heat, making control of heat more critical to reliable operation.

Furthermore, as the size of electronic equipment has decreased, the amount of electronic equipment in each rack and power consumption of the equipment has increased.
