With the raised floor system for the air conditioning of IT and server cabinets in data centers, Huiya IT-Systems recently introduced cost-efficient Alternatives to pressurized floor air conditioning. The first closed-loop system consists of installing one of the CLS side coolers, which are only 30 centimeters wide, next to or between two server racks that are to be cooled and are closed at the front and rear. Two further Huiya China access floor solutions are based on the enclosure with "cold section" roof elements and sliding doors, which create completely closed cold aisles with very little air volume.

Both OLS side coolers are used, which are designed in such a way that - to match the chosen solution - they can be bayed on server racks with front and rear perforated doors or with closed rear doors. With the enclosed open-loop system, the side coolers suck in the air heated by the servers from the room, with the enclosed closed-loop system directly from the rear of the cabinet, cool it down with the help of the integrated air / water heat exchanger and blow it turn them off in the cold aisle.

Since raised floor solutions do not require a raised floor compared to other systems, significant cost savings can already be achieved when building a data center. According to the provider, the Huiya solutions are also more effective during ongoing data center operations because the system-related pressure loss of a raised floor solution is significantly higher. Last but not least, the smaller volume of air to be cooled has proven to be economically advantageous, as it can be promptly adapted to the actual needs of the data center as well as to the individual needs of individual racks.

In addition to the integrated coolers and the cold section containment, the operators can also cool their computer rooms with separate air conditioning units that blow freely into the room.

This additional installation, which lowers the temperature of the ambient air, does not change the overall energy balance, as the total heat load to be managed is determined by the built-in components.
