HP Modular Cooling System manual HP MCS chilled water requirements

The HP MCS G2 supports the front-to-back cooling principle. It evenly distributes cold supply air at the front of each rack so components receive adequate supply air regardless of their position or density. Warm exhaust air collects in the rear of the rack. Fans direct it into the heat exchanger where it is cooled and re-circulated to the front of the rack. Condensation flows through a discharge tube to a tray integrated in the base assembly. The HP MCS G2 can be configured to cool 35 kW of equipment in a single rack or two racks of 17.5 kW each (Figure 10).

The HP MCS G2 includes an Automatic Emergency Door Release Kit designed to open the front and rear doors in case of a sudden temperature increase. The open doors let ambient air cool the equipment.

Flexible installation capabilities allow you to place the HP MCS G2 in locations not originally intended for IT equipment or in older data centers not designed for high-density, high-kilowatt systems.

HP MCS chilled water requirements

There are three potential sources of chilled water for the HP MCS G2:

•Direct connection to the building’s chilled water system

•A dedicated chilled water system

•A water-to-water heat exchanger unit connected to a chilled water system or building water system

The HP MCS G2 connects directly to the facility’s chilled water supply. When it is necessary to isolate the fluid supply/return loop from the main building water system, we recommend using a separate water-to-water heat exchanger. The heat exchanger provides easier control and monitoring of water quality. It also lets you maintain a higher water temperature to reduce condensation.
