Air Conditioning

Air Conditioning

A large proportion of the total power consumption of the data center comes from cooling. That is why the cooling system in the data center often has the most significant energy-saving potential. Properly selected cooling system is able to maintain the optimum temperature in the data center, avoiding overcooling.

In modern machine rooms for cooling, the most commonly used cables are water-cooled or so-called “hot”/“cold aisles” between the rows of server racks. Free-cooling, in which cold outside air is used by chillers of the cooling system, is an efficient and environmentally friendly solution for data centers. When cooled, unclaimed heat is formed, which can then be used, for example, to heat rooms and stairwells.

The data processing center can also be cooled by connecting to the network of the district cooling station (if there is one in the area). Chilled water from the production plant is delivered to end users through pipes. Such a cooling system allows re-use of energy, since the heat generated during the cooling process can be used to heat the area and in places where heating is required.

Several types of air conditioning systems are suitable for cooling a medium-sized data center - cabinet air conditioners, in-row air conditioners, and solutions based on free cooling technology.

F.A.Q about Air Conditioning

Hot Aisle Containment System (HACS)

Hot Aisle Containment System is a professional climate control system. Designed for technological rooms that require maintaining the specified parameters of temperature, humidity and air purity with high reliability and accuracy.

In-house conditioners

In-row air conditioners are designed for the removal of ultra-high heat loads typical of modern data centers. Ideal for "hot"/"cold corridors", providing additional cold air to the cold corridor.

Rack cooling systems

In-cabinet air conditioner is mounted in a hermetically sealed rack. It is used when there is no cooling capacity reserve in the data center, when it is necessary to add a rack with electronic equipment to the data center.

Chillers

Chillers cool (or heat) the heat-transfer fluid that is fed into the piping system, from where it enters the heat exchangers and fan coil units. The heat carrier has a higher heat capacity than the air.

Cooling towers

The principle of the cooling tower is the cooling of a large volume of water by a directed stream of atmospheric air. This type of equipment is used in various systems of circulating water supply to lower the temperature of heat exchangers.

Adiabatic systems

The principle of the adiabatic cooling system consists in spraying purified water from impurities in the form of tiny droplets into hot air. Water evaporating in the air can cool it to a temperature close to that of a “wet thermometer.”

Outdoor units

Remote components of a precision air-conditioning system (condensers, compressors) are mounted outdoors and are connected to a precision air conditioner and a direct evaporation system by refrigerant lines.
