The use of ‘electronic friendly’ refrigerant will prevent the electronic equipment from getting destroyed in the rare event of a refrigerant leak. Obviously, there is no need for a leakage protection as in Chilled Water systems.
The system can be expanded by adding Indoor Units and Outdoor Units as they are needed. Energy consumption is almost linearly proportional to the refrigeration energy required.
Most of the system components can be replaced while the system is working.
There are many ways to ensure system redundancy, such as double battery Indoor Units, double refrigerant piping, etc. Furthermore, if any Indoor Unit is out of order, the neighboring units will cool the equipment of the one which is not working.
The system is perfect in order to avoid ‘hot spots’ in the room just by placing one of our Indoor Units. In this way, one high density rack will not cause trouble to the whole DataCenter, increasing the energy consumption by changing the temperature setpoints of the entire room.
The systems are also very interesting when an increase of the Cooling Capacity occurs and the user does not want to remove the entire system. In that case, it is possible to install some Indoor Units in the higher density racks while the rest of the system will continue working with little interference.
