An analytical method for automated refrigeration in data centers

Abstract

The invention discloses an analysis method for automatic refrigeration of a data center, which collects a combined cabinet temperature measuring device, an area temperature monitoring device, an outdoor environment monitoring device, an active airflow drainage ventilation device, and a data center precision air conditioning system through a data acquisition system and the operating parameters of the fresh air system of the data center, and transmitted to the control model calculation of the data recording and analysis system, and the calculation results are transmitted to the control system, and the control system controls the active airflow ventilation device, the precision air conditioning system of the data center and the fresh air system of the data center Perform closed-loop control. The present invention integrates the precise air-conditioning system and the fresh air system of the data center, optimizes the cooling delivery method, and intelligently controls the air intake volume of the active airflow drainage ventilation device according to the real-time heat dissipation analysis of the cabinet temperature, and efficiently utilizes the existing cooling capacity of the machine room to achieve better Cooling effect, and the fresh air system and active airflow drainage ventilation device are connected separately to the UPS, to avoid the rapid rise of the temperature in the data center caused by the short-term power outage of the mains, and the business interruption caused by the overheating of the system equipment.

Description

technical field [0001] The invention relates to an analysis method for automatic refrigeration of a data center, belonging to the technical field of data centers. Background technique [0002] With the continuous development of computers, communications and related industries, the data center adopts the downflow mode. The construction scale of the computer room is getting larger and larger, the system integration is getting higher and higher, and the equipment density is getting higher and higher; the current business Due to the influence of system construction requirements, equipment layout rationality, and computer room construction environment, the data center has the following problems: [0003] 1) The load distribution of server equipment is uneven, the heat density of the cabinet is high, and local hot spots; [0004] 2) The refrigeration system has a low degree of integration and a single system, mainly using the precision air conditioning system as the source of ref...

AI Technical Summary

Problems solved by technology

[0003] 1) The load distribution of server equipment is uneven, the heat density of the cabinet is high, and local hot spots;

[0004] 2) The refrigeration system has a low degree of integration and a single system, mainly using the precision air conditioning system as the source of refrigeration;

[0005] 3) The precision air conditioning system cannot perform fixed-point cooling according to the actual heat dissipation requirements of the cabinets in the data center;

[0006] 4) The precision air conditioner has a single function, high equipment power, and high energy consumption in operation. Under normal circumstances, it cannot be connected to UPS power supply. When the data center encounters a power outage, it cannot provide cooling when the cabinet equipment in the data center is powered by batteries.

[0007] If the above-mentioned problems cannot be effectively solved, it will lead to high energy consumption in the operation of the data center, business interruption, equipment damage, and great economic losses.
