B) Data Centre Cooling

Data centres are high-capacity enclosed spaces that generate considerable amount of heat. It is essential to control the environment in the data centre in order to maximize the availability and performance of the equipment.

Heat can be leave in data centre and server room in five different ways. These are:

Conduction: Heat can flow through the walls of the space.
Passive ventilation: Heat can flow into cooler air via a vent or grille without a fan.
Fan assisted ventilation: Heat can flow into cooler air via a vent or grille that has a fan.
Comfort cooling: Heat can be removed by a building's comfort cooling system.
Dedicated cooling: Heat can be removed by a dedicated air conditioner.

In-Row cooling Solution for Data center

With new innovations coming up each day in technology, Cooling technology isn't left behind. Hence now data center cooling has a new inventive approach with In-Row cooling architecture paving way into data center cooling systems. This system provides a very predictable way of addressing the heat generated within a data center or even a small server room by any IT equipment. The basic process involves capturing of heat from any IT equipment in the hot aisle and neutralize the heat before t mixes in the room. Datacenters have always been facing thermal issues due to hot air mixing. In-row cooling resolves this issue, however there needs to be some design modifications and practices that should be followed so as to ensure that the specific design of the system is maximized to remove the heat that is being generated.

The Technology of In-Row Cooling

In-row is the new technology in high density cooling. It as revolutionary as any new standards in cooling can get that can change the rules. It changes all the rules. Rated at up to 30KW ( ~8.5 tons/105,000 BTUs) it is only 12" wide by 42" deep.(3 ½ sq. ft.). Occupying only 1/2 rack of row space this unit fits directly into existing rows of cabinets. Not requiring any additional side clearance space, this new ground-breaking design has several benefits.

The smaller the distance between the air conditioner and its heat source; the less likely it is for hot and cold air streams to mix. Typically an In-row cooling system is a computer room air conditioning system that follows a horizontal airflow pattern. This pattern is specifically designed to handle hot aisle/cold aisle configurations. The design is quite versatile as it draws warm air directly from the hot aisle, gets cooled and then gets distributed into the cold aisle. While this process it is ensured that the equipment inlet temperatures are maintained at a constant value and that it is also adequate for proper operation. The system as it couples the air conditioner with heat source produces a more efficient and direct return air path to the system.

In Row Cooling undoubtedly improves energy efficiency close coupled cooling.

In-row cooling unit falls under the general category of close coupled cooling. As compared to tradition, perimeter CRAC's with raised floor cooling, close coupled cooling is more energy efficient. This results from the fact that the air that needs to travel (cool and warm return) has to travel a much shorter distance, wherein it improves the effective net cooling power. This also lowers the fan energy that is required to move the air. This in-turn prevents hot and cold air from mixing thus further enhancing efficiency.

Infrastructure In Row is a family of computer room air conditioning system. These are designed for installation in the row for optimized sensible cooling and increased efficiency. The functioning is such that the units capture het directly from the host aisle and distributes cool air to the front of the cabinets. This ensures that all the equipment temperatures are consistently held to set point conditions. In addition, air-cooled and water cooled models are also available.

Cooling Containment System

We offer cooling containment system for data center like Cold Aisle Containment System (CACS) and Thermal Containment high density cooling system.

Cold Aisle Containment (CACS)

The Cold Aisle Containment System (CACS) is most commonly deployed in traditional perimeter-based cooling environments. A typical cooling environment uses the entire room as a hot air return plenum and is used to deliver cold air via the raised floor plenum to the cold aisles. The CACS encloses the cold aisle allowing the rest of the data center to become a large hot air return plenum. By containing the cold aisle, the hot / cold air streams within the data center are separated.

Mostly cold aisle containment provides targeted cooling on a data center floor. Cold Aisle comes with many operational advantages. With this versatile system, air conditioners can work with better capacities and efficiency, servers get an assured and consistent inlet temperature and the chiller plant can become more efficient by supplying and receiving elevated water temperatures. These improvements not only great on paper, they also produce a very significant and tangible result i.e. it confers a reduction in capital and/or operational expenses.
