Expansion cooling

The expansion cooling is the classic cooling method based on a refrigerant and direct evaporation. However in design and use of the systems, there are several things to consider.

Here classic split units for cooling are used. They come with an internal unit for cooling of components and an outdoor unit for cooling production.

These two devices are connected in a closed refrigeration cycle with a liquid, chemical cooling agent. This cooling agent is evaporates inside the indoor unit, and enables cooling / absorbs heat. It then is passed as gas to the outdoor unit where a compressor brings the gas back to a liquid form, using electrical energy as well as passing the excess heat to the outside air.

Should be noted here that this process is to be carried out as effectively and efficiently as possible. The devices should be inverter-controlled, so not only running I/O at full power but individually regulated according to the cooling demand. This saves a lot of energy.

The next potential for saving energy is the intelligent use of refrigeration. With normal wall-mounted split unit, for example, the distance from the wall up to the server components must be bridged in order to be cooled. This can lead to mixing of cold air with the warm discharge air of the systems, resulting in high energy loss. It is better here, to minimize the distance between the cold source and consumer, and clearly separate cold and warm air

streams from each other.

innovIT AG holds innovative solutions available in the field of expansion cooling. There are the Split systems on direct expansion base with up to 30kW cooling capacity with only one indoor unit. This is an energy-efficient Air conditioning system - Made in Germany. You can win up to 50% energy savings compared to commercially available systems by use of electronic injection and efficient inverter technology.
