Abstract

A space-saving, high-density modular data pod system and an energy-efficient cooling system are disclosed. The modular data pod system includes a central free-cooling system and a plurality of modular data pods, each of which includes a heat exchange assembly coupled to the central free-cooling system, and a distributed mechanical cooling system coupled to the heat exchange assembly. The modular data pods include a data enclosure having at least five walls arranged in the shape of a polygon, a plurality of computer racks arranged in a circular or U-shaped pattern, and a cover to create hot and cold aisles, and an air circulator configured to continuously circulate air between the hot and cold aisles. Each modular data pod also includes an auxiliary enclosure containing a common fluid and electrical circuit section that is configured to connect to adjacent common fluid and electrical circuit sections to form a common fluid and electrical circuit that connects to the central free-cooling system. The auxiliary enclosure contains at least a portion of the distributed mechanical cooling system, which is configured to trim the cooling performed by the central free-cooling system.

First claim

What is claimed is:

1. A modular data pod system, comprising:
computer racks arranged to form a first volume between an inner surface of wall members of an enclosure and first sides of the computer racks and a second volume formed of second sides of the computer racks;
a computer rack covering member configured to enclose the second volume;
a data pod covering member forming a third volume coupling the first volume to the second volume;
an air circulator configured to continuously circulate air through the first, second, and third volumes;
a heat exchange member in air communication with the air circulator and with the first, second, and third volumes; and
a cooling system in fluid communication with the heat exchange member, the cooling system including:
a free cooling system configured to cool a first refrigerant flowing through the heat exchange member using cooling water and atmospheric air; and
a mechanical cooling system separate from and coupled to the free cooling system, the mechanical cooling system configured to cool the first refrigerant flowing through the heat exchange member using a second refrigerant.

2. The modular data pod system according to claim 1 , further comprising a variable fan drive, wherein the variable fan drive varies the speed of the air circulator depending on environmental conditions associated with the modular data pod system.

3. The modular data pod according to claim 1 , wherein the heat exchange member is disposed adjacent to the third volume.

4. The modular data pod system according to claim 1 , wherein the heat exchange member is disposed adjacent to the air circulator.

5. The modular data pod system according to claim 1 , further comprising a dedicated electrical power supply electrically coupled to the computer racks.

6. The modular data pod system according to claim 1 , wherein the cooling system is disposed external to the enclosure.

7. The modular data pod system according to claim 1 , wherein the mechanical cooling system is configured to cool the first refrigerant flowing through the heat exchange member as a function of an amount by which the free cooling system has exceeded its maximum cooling-capacity.
