120 KVA Modular Data Centers Computer Room Hot Aisle Cold Aisle System

Product Introduction

The cold aisle closed system is used to control the refrigeration environment. The cold air sent from the air conditioner in the aisle is filled into the sealed aisle, and the cold air is guided to enter from the front door of the cabinet. After the equipment is cooled, it is discharged from the back door of the cabinet in time to form a flowing air flow. The main function is to prevent the mixing of hot and cold airflows and return to the air conditioning outlet in time to improve the efficiency of the use of cold air, thereby achieving the purpose of energy saving and emission reduction.

The cold aisle airtight components used in the host room, the materials and devices used, fasteners, seals, their mechanical, chemical, electrical properties, and various performance testing methods should meet the standards of the China Standard, the communications industry standards and the IEC Relevant standards.

Coolnet mini-modular data center can flexibly adopt the layout of double-row cabinets + cold/hot aisle or single-row cabinets + cold/hot aisle according to user site conditions. Under the two structural layouts, all subsystems such as cabinets, channels, power supply and distribution, refrigeration, security, environmental monitoring and management, and wiring can be integrated according to user needs, providing customers with new data of rapid deployment, high efficiency and energy saving, compact space, and flexible expansion Central solution.

Feature & Benefits

Rack Part

The modular data center can be configured with N cabinets, including server cabinets, network cabinets and integrated wiring cabinets.

Appearance of the cabinet

The cabinet size of the modular data center configuration is uniform, the cabinet conforms to the IEC60297-1 standard, and the front and rear air ducts are adopted. The appearance of the cabinet is shown in the figure.

Aisle Containment -Modular design

The Aisle of the modular data center is mainly composed of end doors and skylights.

End gate

(1) The end doors of the aisle are divided into sliding doors and double doors, which can be selected according to customer needs.

(2) Sliding door size: height × width × depth = 2050mm × 1200mm × 42mm.
The sliding door adopts a sliding structure, the cabinet is used as the carrier, and the upper and lower rails are installed to ensure the independence of the closed channel system. The door panel is bent from 1.5mm cold-rolled steel plate, and tempered glass is installed in the middle to ensure the visibility of the area in the passage.

Adopting modular unit design concept, each unit can be installed and disassembled independently, and can be closely connected with adjacent units, which is convenient for disassembly and assembly; at the same time, it is also suitable for maintenance and management of other equipment on the channel.
Good sealing
All unit modules in the hot and cold aisle system are connected precisely, and the parts are sealed with good sealing tops or sponge strips, which not only maintains the aesthetics, but also prevents the leakage of cold air in the cold aisle.
Good light transmission
The system is composed of toughened glass with strong light transmittance

Power Supply- Modular UPS

According to the power supply requirements of large and medium-sized data centers, a modular UPS solution has been introduced, which can be flexibly configured with 80-300kVA modular UPS according to the customer's system power supply requirements. The module adopts advanced high-frequency switching technology, fully digital DSP control technology and the world’s leading active PFC and LLC topologies to achieve high input power factor, accurate output current sharing performance, and reliable monitoring and management system. The equipment provides safe, reliable and pure AC power.

Cooling System - In Row Air Conditioning Unit

Inverter In Row air conditioners are tailor-made high-density cabinets, adopts advanced frequency conversion technology and uses the environmentally friendly refrigerant R410A. The output cooling capacity is adjusted in real time according to the change of the detected load, to avoid frequent start and stop, and to ensure the temperature of the computer room environment.
Compared with fixed frequency air conditioners, the annual energy saving rate of variable frequency inter-train air conditioners can reach 29%.

Monitoring System

The monitoring system system has the characteristics of simple configuration, strong access, and high reliability. It can manage all power, environment, and cooling in data center, integrate mainstream brand access control, video and other security systems, through distributed collection, high concurrent processing capabilities Meet the needs of networked monitoring and management of multiple computer rooms, allowing data center operation and maintenance personnel to control the operation safety of the computer room in real time.

(1) The ventilation rate of the front and rear doors is 70%.

(2) Two vertical PDUs can be installed at the rear of the cabinet.

(3) The exact position of each "U" is marked on the vertical installation column of the cabinet. The front door, back door and side panels of the cabinet can be locked and can only be opened with the provided special key.
