CRCC 0020 – 0060
Chilled Water Rack Cooler unit Total cooling capacity gross 16,1 – 74,7 kW
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. In hydronic version where the cooling is ensured by the use of an external chiller. 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. 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.
- IN-ROW – Basic, IN-ROW air flow configuration
- ENCLOSURE – Basic, ENCLOSURE air flow configuration
The CRCC unit combines the efficiency of a hydronic system for the extraction of heat with the use of last generation fans EC electronic commuteted , to obtain values of EER more than 100. The reduction of the temperature of the air exhausted allows the use of H2O very high cooling 14-20 ° C by the CRCC, that if on the one hand prevents unpleasant phenomena of condensation (SHR = 1) will allow the other ´use of only the external system in chillers Frecooling Climaveneta.
The InRow and Enclosure versions are both arranged with hydraulics connections and electric supply from top or bottom side, so as to allow a quick and easy installation in any condition, whether or not foreseen the presence of a raised floor.
- IDM – INTEGRATED DYNAMIC MANAGEMENT OF TEMPERATURE
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).
Both the Enclosure and InRow are developed to ensure maximum RELIABILITY ‘the system by total REDUNDANCY cooling system guaranteed by the new version DUAL COIL dual power supply, dual battery raffreddamenmto and double regulating valve completely independent to ensure 100 % back up in the air conditioning system. This allows you to connect your new versionbe DUAL COIL from one side to the primary system FREECOOLING (Circuit 1) and the other to a chiller chilled water in total Back up.
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.
