Coolant source planning

A number of factors relating to a chilled water distribution system must be considered during the site preparation process, including the following:

•Redundant water configurations (For more information, see Appendix B.)

•Type of water source (shared water or dedicated chilled water loop)

•Maximum and minimum temperatures of building chilled water plant, and target chilled water temperature of dedicated loop based on total cooling capacity required and planned

•Viscosity of the chilled liquid, combined with the length and elevation changes in piping, determined by selected route, which can affect the selection of pipe size

Caution:

The minerals and chemicals typically found in tap water can react with metallic elements used in the MCS 5042. Electro-chemical reaction might cause scaling, corrosion, leaks, and blockage, ultimately resulting in reduced efficiency of the cooling system and even damage.

HP recommends that the water source for the MCS 5042 be a dedicated chiller unit or water-to-water heat exchanger that enables line isolation, better control of individual systems, and regulated water quality. The chilled water source for this loop is provided by one or more chiller systems. Advantages of using a dedicated loop include:

•Easier scheduling of maintenance to either a building system or dedicated MCS 5042 loop

•Easier maintenance of water quality parameters in the dedicated closed loop

•Better temperature and flow regulation to guarantee the needs of the MCS 5042

•More flexibility to regulate water temperature in order to reduce the potential for condensation

The use of building chilled water for the MCS 5042 unit is possible under certain conditions. However, consult with a qualified facilities design expert to determine whether this approach is possible within your specific data center. Refer to the requirements for water quality, temperature, and flow rate described in this section. Regardless of chilled water service approach, consult with a qualified facilities design expert to analyze new and existing systems and specify new work to insure water quality, temperature and water flow requirements can be met. The new work must meet all local safety and building code requirements as well as the customer’s facility quality standards. Piping drawings and schematics included here are diagrammatic to convey a conceptual understanding of the MCS 5042 connection requirements.

Modular Cooling System specifications

The HP Modular Cooling System (MCS) is a state-of-the-art solution designed to efficiently manage the heat generated by high-density IT environments. As data centers face the ever-increasing demand for processing power, traditional cooling methods often fall short, leading to inefficiencies and raised energy costs. The HP MCS addresses this issue with a scalable, flexible design that optimizes cooling performance while minimizing energy consumption.

One of the main features of the HP Modular Cooling System is its modular architecture, which allows for easy expansion and customization based on the specific needs of a data center. This scalability means that as a facility grows or changes, the cooling system can be modified without the need for extensive renovations or replacements. The MCS can be installed in various configurations, further enhancing its versatility.

The technology behind the HP MCS includes advanced cooling methods such as direct evaporative cooling and chilled water cooling. Direct evaporative cooling utilizes the principles of evaporative heat exchange to cool air without excessive energy consumption, making it an eco-friendly choice. In contrast, chilled water cooling uses a network of pipes filled with chilled water to remove heat from the server environment efficiently. This combination allows the MCS to adapt to various heat loads and ambient conditions.

Another notable characteristic of the HP Modular Cooling System is its intelligent controls and sensors. These components continually monitor temperature and humidity levels within the data center, automatically adjusting cooling output to maintain optimal conditions. This proactive approach helps to prevent overheating, reduces energy usage, and ensures the longevity of IT equipment.

Energy efficiency is further enhanced through the MCS's integration with HP's monitoring and management software. This software analyzes cooling performance trends, providing actionable insights for facility managers, enabling them to make informed decisions regarding cooling strategies. Additionally, the system is designed with environmentally sustainable practices in mind, aligning with global initiatives to reduce carbon footprints and promote green technology.

The HP Modular Cooling System stands out for its combination of innovative technologies, flexibility, and a commitment to energy efficiency. As data centers continue to evolve, the MCS remains a crucial asset in the pursuit of optimized performance and sustainability, providing a reliable solution to meet the demanding cooling needs of modern IT infrastructure.
