IT Load per Rack(kW)Server QuantitySubtotal IT Load (kW)
Total IT Load (kW)640

Server IT Load Data

a. Power Input: 400VAC – 3 phase 50HZ
b. Site Layout: As below Figure 3-2.
c. Server Rack IT Load: As above Figure 3-1.
d. Server IT load is evenly distributed for the DC.
e. Total cooling capacity: 640kW
f. Supply air temperature: 22°C
g. Return air temperature: 32°C

Site DC Layout
  • Based on the site situation and requirement, total 6 nos. of CRAC units (3 no.s per CRAC Room X 2 CRAC Rooms) to be proposed by fully utilized the cooling equipment space.
  • For the cooling configuration, 6 nos. of CRCAs (3 no.s per CRAC Room X 2 CRAC Rooms) will be in hot standby operation with spare 20% Cooling capacity as redundancy.
  • Data center design in total cold air flooding with hot aisle containment and return ducting concept where the room will be emersed by the cold air and hot air will be channeled by the containment and return ducting system back to the CRAC.
  • Mechanical and electrical installation is proper planned to achieve better space management and ease for the maintenance work.
  • Perforated wall will be used to further improve the air distribution and cooling performance in the DC room.

DC Server IT Load Distribution

We are seeing inlet and outlet temperature of the server racks maintainns at normal control range based on ASHRAE requirement after initial CFD simulation based on the input data provided by client. The Hot Aisle Containment (HAC) approach encloses the hot aisle with return ducting above the aisle between adjoining racks and with doors at the end of the aisle. This allows the hot air from the IT racks to be contained and delivered to the CRAC air inlets. The HAC prevents cold air from mixing with warm air or being obstructed by surrounding equipment/sources before it reaches the servers. The Figure 4-6 is telling the same story and proves further on the HAC design concept.

Product T&C

I. Level 0 Commissioning (Pre-commissioning Documentation)
* documentation procedure and checklist on functional operability of equipment / component
within the system in order to ensure the system is ready for start-up.
* CxA shall review and approve the FWT procedure(s)

II. Level 1 Commissioning (Pre-commissioning Documentation)
* must be submitted to the employer/design engineer and CxA at least sixty (60) working
days in advance of the test for review and approval
* a. Capacity of the equipment.
* b. Safety features of the equipment.
* c. Equipment safety/maintenance access.
* d. A description of how conditions will be simulated in relation to the equipment
* e. Control and monitoring of equipment
* f. Sequence of Operations (SOO)

III. Level 2 Commissioning– Pre-Start Up Documentation.
* Pre-Start up Documentation for Manufacturer Equipment
* Pre-energized equipment inspection

IV. Level 3 Commissioning – Equipment Start-Up and Pre-Functional Testing
* prepare a detailed energization, start-up, and commissioning plan in consultation
with the CxA, Contractor, and design consultant
* The start-up activities of the equipment shall be performed by an authorized
technician of the Sub-Contractor in accordance with the approved start-up plan.
* Online Building Management System

V. Level 4 Commissioning – Functional Performance Testing (FPT)
* From individual components, through complete systems the increasing interactions
between components and other systems often does not produce the desired results. CxA
team directs functional performance testing with assistance from an authorized
manufacturer Sub-Contractor‘s technician and the installing contractor.

VI. Level 5 Commissioning – Integrated System Testing (IST)
* In the IST, the facility is validated through a series of automated test procedures,
performed without any human intervention, that are used to verify the system’s
ability to respond to several anticipated situations. The test is intended to validate
the performance of the systems under extreme operating conditions.
