1. Introduction

1.1 General

The Cold Row precision data center air-conditioning system covered by this manual uses the latest, state-of-the-art control technology. It uses the finest materials available in the industry. The unit will provide years of trouble-free service if installed and maintained in accordance with this manual. Damage to the unit from improper installation, operation, or maintenance is not cov- ered by the warranty.

STUDY the instructions contained in this manual. They must be followed to avoid difficulties. Spare parts are available from Black Box to ensure continuous operation. Using substitute parts or bypassing electrical or refrigeration components to continue operation is not recommended and will VOID THE WARRANTY. Because of technical advancements, components are subject to change without notice.

All Cold Row systems are designed to be installed indoors.

1.2 Product Description

Cold Row systems are available in water-cooled, water/glycol-cooled or air-cooled direct expansion (DX) configurations. DX-based Cold Row systems are designed to operate with R410A refrigerant.

DX-based Cold Row cabinets are 12" wide. The cooling capacity in KW/Hr will depend on the compressor size. Refer to the unit nameplate to identify the capacity of your system.

NOTE: Cold Row systems capture and neutralize heat within close-coupled, rack-based environments. Any use beyond what is described in this manual is deemed to be not intended. Black Box is not liable for any damage resulting from improper use.

The functional modes of operation are cooling and dehumidification, which provides localized cooling to offset hot spots in data centers.

The Cold Row system captures high-temperature (hot aisle) discharge air from adjacent rack-based IT equipment and reintroduces it as conditioned air through the front of the unit (cold aisle).

The system is equipped with highly reliable Electronically Commutated (EC) fans that offer considerable energy cost savings and long life. Using an electronically commutated permanent magnet DC motor eliminates AC inverter whine. Fan speed is continuously adjustable via a signal from the system controller without the use of VFDs. EC fans offer energy-efficient, quiet, low-vibration operation.

An advanced E2 series microprocessor controller is mounted inside the Cold Row electric box. The controller provides the following features: input/output monitoring status, full integrated control of cooling and dehumidification, multi-unit control, and remote communication with a Building Management System (BMS). The controller may interface directly to a BMS, so you can monitor the performance of the air conditioner and adjust operating parameters.

The E2 user interface display panel is typically factory mounted on the front access panel of the unit.

CRDX-W-FS-12KW, Black Box Cold Row DX, CRDX-W-FS-24KW, CRDX-A-FS-24KW, CRDX-A-FS-12KW specifications

The Black Box CRDX series consists of high-performance cooling solutions designed to maintain optimal temperature conditions in data centers and server rooms. Key models in this series include the CRDX-W-FS-12KW, CRDX-W-FS-24KW, CRDX-G-FS-12KW, and CRDX-A-FS-24KW. These units are engineered to provide efficient cooling while addressing the rising demands of modern IT infrastructure.

One of the standout features of the CRDX series is its cold row design. This configuration enables targeted cooling delivery directly to the equipment, enhancing efficiency and reducing energy consumption. The airflow management in these models ensures that cooled air is directed where it is needed most, minimizing hotspots and maximizing cooling performance.

Both the CRDX-W-FS-12KW and CRDX-W-FS-24KW models utilize advanced refrigerant-based cooling technology. These units are equipped with electronically commutated (EC) fans, which are highly efficient and quieter than traditional fan technologies. This innovation not only lowers operational costs but also creates a more comfortable environment within the data center.

The CRDX-G-FS-12KW model stands out for its hybrid capabilities, offering both chilled water and direct expansion cooling options. This versatility allows facility managers to choose the best cooling approach based on their specific requirements and current infrastructure. The hybrid system can optimize energy consumption and enhance cooling efficiency, contributing to lower operating costs.

Another noteworthy feature across these models is their intelligent controls and monitoring capabilities. Equipped with sophisticated sensors and control systems, operators can gain real-time insights into temperature fluctuations, humidity levels, and unit performance. This data aids in proactive maintenance and ensures that cooling systems are operating at peak efficiency.

The CRDX-A-FS-24KW, on the other hand, is designed with a focus on adaptability and scalability. This model can be integrated easily into existing network setups, making it an excellent choice for facilities that anticipate future growth or need to adapt to changing cooling demands.

Overall, the Black Box CRDX series exemplifies the latest advancements in cooling technology, offering innovative features designed to support high-density computing environments. With their efficient cooling capabilities, intelligent controls, and flexible design options, these models provide reliable solutions for data centers looking to enhance their cooling systems while reducing operating costs.
