最近,一些制造商已经开发新的CRAC机型,可使用多级压缩机来改变气流,但大多数现有的CRAC机组只有开或关的控制。 CRAH (机房空气处理)机组的工作原理与高层商业写字楼中的冷冻水空 …

CMF room-based inverter CRAC (refrigerant pump) can use the difference between indoor and outdoor air temperature to cool the computer room. At low ambient (outdoor) temperature, the efficiency in refrigerant pump mode is 10 times the one in compressor refrigeration mode, effectively reducing the PUE value of the served room. Application scenarios: data center, telecom equipment and computer ...

CRA Row-based Inverter CRAC (Air-cooled) CRA row-based inverter CRAC (air-cooled) is designed for the medium and high thermal density data center. It is installed close to the heat source, shorten the flow path of cold air to accurately process the sensible heat generated by the server. It is the ideal choice for the green energy-saving data center and various electronic equipment rooms ...

2022年3月1日 · CRAC 和 CRAH 冷却装置之间的主要区别在于 CRAC 装置使用制冷剂和压缩机，而 CRAH 装置使用冷冻水和控制阀。 CRAC 冷却装置具有更简单的功能，因为通常只有一种模式一旦打开。

CRC row-based CRAC (chilled water) is more suitable for scenarios with limited on-site installation (no need to install outdoor units) while maintaining accurate cooling characteristics and close to the heat source, helping the continuous development of green data centers.

The main difference between CRAH and CRAC units is how they cool their surrounding environments. CRAC units use both refrigerants and compressors, while CRAH units use chilled water and control valves.

Keling's Vertiv Liebert PEX4 Precision Air Conditioning System is designed for data center cooling. This CRAH solution maintains optimal temperatures and humidity levels, ensuring critical infrastructure is protected and performs reliably.

CDA rack inverter CRAC is a cabinet type temperature control product, especially designed for high thermal density data centers. Placed closely to the heat source on the cabinet rack, it can accurately process the high sensible heat generated by the servers in the cabinet, effectively prevent local hot spots, and help green data centers to develop continuously. Application scenarios: all kinds ...
