8. Product Guide Specifications

SUMMARY

This specification describes requirements for a precision environmental control system. The Cold Row CW is a row-based cooling system that provides precision temperature control (and humidity control for the 24" models) for computer rooms, or rooms containing telecommunications or other highly sensitive heat load equipment, where continuous 24 hours a day, 365 days a year air conditioning is required. Designed with both front and rear access, Cold Row CW systems require minimum floor space. The supplied system has ETL Certification. The part numbers are CRCW-12 and CRCW-24.

DESIGN REQUIREMENTS

The environmental control system is a Cold Row Chilled Water (CW) factory-assembled unit. The unit is designed for a row-based installation with removable front and rear access panels. No allowance for side service access is required, however, removable side access panels are provided for additional access.

Cold Row CW units are especially adapted for both raised and non-raised floors. The air handling system is specifically designed for high sensible heat ratio. Each system is capable of handling ___CFM. The unit shall have the cooling capacity of ___BTU/H, and the sensible cooling capacity of ___BTU/H based on entering air condition of ___°F (°C) dry bulb and ___°F (°C) wet bulb. The main fan motors shall be ___HP. The unit shall have a power supply of ___volts.

QUALITY ASSURANCE

The manufacturer will maintain a set of international standards of quality management to ensure product quality. Each system will be subjected to a complete operational and functional test procedure at the factory before shipment.

CABINET

Access panels must be fabricated from 18-gauge galvannealed steel and must be securely fastened to the 10-gauge base and

16-gauge top plates, fabricated from galvannealed steel. Both must be painted with a 2-ply epoxy finish to match and to protect from corrosion. The main unit color shall be satin black. Armaflex® elastomeric thermal insulation must be used to insulate the cabinet, block noise, and prevent damage from vibration. Casters and leveling feet shall be included to ease the installation and level the equipment with existing IT solutions.

AIRFLOW PATTERNS

All units must be designed using a front discharge with a rear return airflow pattern. An optional plenum with a front diverted discharge pattern is available.

AIR FILTRATION

All units must be equipped with permanent washable filters. These filters must consist of an open cell structured polyurethane foam with a roll-formed 3000 series aluminum frame. Filters shall meet both UL® 900 and UL 94 HF-1 standards.

MECHANICAL COMPONENTS

BACKWARD-INCLINED, PLENUM-STYLE FAN, WITH AN EC MOTOR

The blowers must be backward-inclined, plenum-style fans with an electronically commutated (EC) motor, for maintenance-free operation. The motor must include: integrated electronic control board and direct microprocessor control signaling for fan speed control, soft-starting capabilities, and integrated current limitations. Each fan must be low noise, low vibration manufactured with an anti-corrosive aluminum impeller. Each fan impeller must be dynamically and statically balanced in two planes to minimize vibration during operation.

cold row chilled water(CW) engineering manual, crcw24, crcw-12 specifications

The Black Box Cold Row Chilled Water (CW) Engineering Manual focuses on the CRCW-12 and CRCW-24 models, designed for precision cooling in data centers and critical environments. These systems play a vital role in ensuring optimal temperature management, thereby enhancing operational efficiency and equipment longevity.

One of the main features of the CRCW-12 and CRCW-24 units is their high cooling capacity. The CRCW-12 provides a cooling capacity of 12 tons, while the CRCW-24 doubles this capacity with 24 tons. This robust performance makes these units suitable for diverse applications, from small server rooms to large data centers.

Another key characteristic is their modular design, allowing for easy scalability. This flexibility enables users to expand their cooling capabilities as their infrastructure grows, making it an excellent long-term investment. The compact footprint of both models ensures they can fit into tight spaces without sacrificing performance.

In terms of energy efficiency, both CRCW models incorporate advanced technologies such as variable speed fans and compressors. These components adjust their speed according to real-time cooling demand, significantly reducing energy consumption. This smart technology not only lowers operational costs but also contributes to environmental sustainability.

The systems are equipped with state-of-the-art controls that facilitate precise temperature management. These controls enable remote monitoring and management through integrated software platforms, making it easier for facility managers to oversee cooling performance and make necessary adjustments.

Additionally, the CRCW series includes features like dual refrigerant circuits, which increase reliability by allowing the system to maintain operation even if one circuit fails. This redundancy is crucial for mission-critical environments where cooling cannot be compromised.

Noise reduction is another notable characteristic. Both models are designed with sound-dampening technology, making them suitable for environments where low noise levels are essential, such as offices adjacent to data centers.

The use of high-quality materials and components ensures durability and prolonged service life. Regular maintenance is simplified with easily accessible parts, allowing for efficient servicing and lower downtime.

In conclusion, the Black Box CRCW-12 and CRCW-24 cold row chilled water systems are engineered to meet the rigorous demands of modern data centers. Their combination of high cooling capacity, energy efficiency, modular design, and advanced control technologies makes them a preferred choice for reliable and effective temperature management.
