Air conditioner unit refrigeration control system, method and device, and air conditioner unit

Abstract

The invention relates to the technical field of an air conditioner and discloses an air conditioner unit refrigeration control system, method and device, and an air conditioner unit. The air conditioner unit includes multiple air conditioners. A refrigeration control system of each air conditioner includes multiple fan units with independently adjustable rotating speed, wherein each fan unit comprises several fans; first temperature sensors assigned in multiple arrays and arranged on air return sides of the multiple fan units, wherein an air return side of each fan unit is provided with at least one row of the first temperature sensors; second temperature sensors assigned in the multiple arrays and arranged on air supply sides of the multiple fan units, wherein an air supply side of each fan unit is provided with at least one row of the second temperature sensors, and the first temperature sensors and the second temperature sensors are arranged in one-to-one correspondence on the air return side and the air supply side of each fan unit; and a control device separately in electric connection with multiple first temperature sensors and multiple second temperature sensors, and used for controlling each fan unit to adjust the rotating speed according to air return temperature and air supply temperature of each fan unit.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a refrigeration control system, method, device and air conditioning unit of an air conditioning unit. Background technique [0002] A data center, commonly known as a computer room, is a complete set of complex facilities. It not only includes computer systems and other supporting equipment (such as communication and storage systems), but also includes redundant data communication connections, environmental control equipment, monitoring equipment, and various safety devices. At present, as the internal chip integration of the server is getting higher and higher, the amount of calculation is increasing, and the heat dissipation of the server or communication equipment used in the data center is also increasing. For temperature and humidity requirements, in order to achieve high-efficiency cooling of equipment, cold air must be organized to enter the interior of the equip...

AI Technical Summary

Problems solved by technology

There will be temperature stratification in the closed cold aisle, and due to the influence of the hot aisle, it will lead to a larger temperature gradient in the cold aisle, and the phenomenon that the temperature at the top of the closed aisle is greater than the temperature at the bottom will be more obvious

In practical applications, when the load is high and the wind speed is low, the reliability of the air conditioner is poor, which easily leads to an excessive temperature difference between the upper area and the lower area of ​​the front door of the server cabinet, or an excessive temperature gradient in the upper area of ​​the front door of the cabinet. Occurs, which leads to poor reliability of the computer room
