CRCX 0051 - 121 / i-HCAT

The indoor vertical air conditioning units CLIMAVENETA RACK COOLER is an effective management system of the Hot Spots in the data center, ensuring low energy consumption and usage possibilities even under extremely high loads for HIGH DENSITY rack ´up and over 40 kW/m2 rack. The use of EC fan systems, featuring last-generation electronic-switching brushless motors, assures excellent performance and low consumption. Available as standard with the dynamic management of N +1 EC fans to optimize consumption and redundancy of the cooling system. Coupled with outdoor condensing unit i-HCAT air-cooled type with axial-flow fans, fitted with INVERTER-DRIVEN HERMETIC SCROLL compressor for operation on R410A refrigerant, mounted on rubber vibration dampers, complete with oil charge, supplied with oil separator to ensure correct lubrication even at minimum speed, and fitted with thermal protector. The i-HCAT is available on versions BASIC ans d LT for low external temperature. PRINCIPLE OF OPERATION These individual units to be positioned between the racks in the row so as to act locally in order to dissipate the load of servers. In InRow versions (CCRC-I) by treating the air is sucked in the back of the unit directly from hot aisle of data center (35 ° C) with significant benefits from the point of view of energy efficiency and cooling capacity, to be cooled and sent on the cold aisle (18-20 ° C) that is in front of the racks where it is sucked by the same. In Enclosure versions (CCRC-E) servers and conditioner are hermetically housed within the same Rack closed structure thus avoiding phenomena of mixing air with the outside, with obvious loss of efficiency in the conditioning. The air is sucked directly into the rack from the back closed directly by the servers (46 ° C) and sent from the front once cooled (25-30 ° C) directly to the servers with considerable savings of energy due to the smaller amount treated air.


ENCLOSURE - Basic, ENCLOSURE air flow configuration

IN-ROW - Basic, IN-ROW air flow configuration




The CRC unit combines the efficiency of use of last EC fans generation and a direct expansion system with inverter compressor (fitted in condensing unit i-HCAT) allowing a great EER value. Thanks to the adoption of inverter DC brushless compressors, these units can reduce by 50% consumptions at part load, if compared to a traditional ON/OFF compressor. This is made possible also thanks to the advantages of variable air flow enabled by EC fans.

The InRow and Enclosure are both equipped with predisposition for passing refrigerant connections and power supply from both above and below, so as to allow a quick and easy installation in any condition, whether or not foreseen the presence of a raised floor.

The units are supplied with a new management algorithm called IDM-INTEGRAL DYNAMIC MANAGEMENT able to prevent stratification of temperature within the rack through the use of 4 sensors (2 on the suction and 2 on the outlet) integrated and independent on the basis the real load in the single stratified BLADE work to optimize the ventilation only when required so as to maximize energy benefits. The IDM also provides the optimal management of the outlet temperatures of the treated integrating the various resources in a DYNAMIC and INTELLIGENT way to avoid unpleasant condensation ensuring (SHR = 1).

CRC units, with their characteristics of dimensional standardization based on the rack, are ideal for all those datacentres where SCALABILITY of the system is a strategic factor.

Perfect integration with systems that minimize the mixing hot and cold air between the aisles and that emphasize the efficiency of such systems.
