Embodiment Construction

[0012] figure 1 is the floor plan of Data Center 1. The data center 1 includes one or more racks (rack 2) and a plurality of CRAC units (CRAC unit 3). Rack 2 consists of one or more computer equipment. E.g, figure 1 There are 25 CRACs and 10 rows of racks, each row has 15 racks. This method can be used for rooms with any number of CRAC units.

[0013] figure 2 Yes figure 1 Front view of CRAC unit 3 shown in . Return air 4 from the interior space of the data center 1 is drawn by supply fans 6 through the top of the unit. After passing a cooling coil 5 it is cooled and becomes cooled supply air 8 . Chilled water, refrigerant or other cooling media flow inside the cooling coil 5 , and their flow is regulated by a cooling valve 7 . The temperature (RAT) of the return air 4 is usually the control target of the CRAC unit 3 . The speed of the blower fan 6 or the cooling valve 7 or another device is adjusted to vary the cooling output of the CRAC unit 3 and maintain the con...

Abstract

Described is an adaptive automatic computer room air conditioner (CRAC) or computer room air handler (CRAH, CRAC and CRAH is referred interchangeably in this article) group control method. This method automatically controls each HVAC unit's on / off status, return temperature set point, fan speed or cooling valve position to secure the data center thermal environment for server's secure running and minimize the cooling energy use. The method creates a comprehensive feedback control loop between temperature sensor network, data center environment and CRACs.

Description

technical field [0001] The invention relates to optimal control and energy efficiency of mechanical cooling systems. Background technique [0002] In the United States, data centers are among the largest and fastest-growing consumers of electricity. In 2013, U.S. data centers consumed an estimated 91 billion kWh of electricity, more than double the power supplied to all homes in New York City, and are expected to reach 140 billion kWh by 2020. To ensure the safe operation of data centers, their cooling systems are often oversized or over-operated to keep them as cool as possible. However, this sacrifices the cooling efficiency, and the cooling energy consumption therefore increases dramatically. It is desirable to have a control logic for an intelligent cooling system that can drive the cooling system to provide an appropriate level of cooling such that safety can be ensured with minimal cooling energy consumption. [0003] Some companies propose to develop control logic ...
