A data centre, network, or server room’s temperature, air distribution, and humidity are monitored and maintained by a computer room air conditioning or CRAC unit. CRAC units have replaced the air conditioning systems under utilisation to cool data centres.
Here are things to know about computer room air conditioning.
1. Managers can regulate a data centre’s temperature, airflow, and humidity using a computer room air conditioning or a CRAC machine.
By pumping air over a precision cooling coil with refrigerant, CRACs cool a data centre. It then exerts extra heat by a glycol mixture, water, or mood.
Although a professional can set up CRAC units in a data centre in various ways, the best location is at the end of the hot aisles. In addition to maximising static pressure in the cold aisle, this assures the return of hot air to the CRAC unit.
Data centre administrators should regularly check the airflow above and below the floor to ensure the CRAC units operate efficiently. To establish whether regions are hot or cold, they must assess the air temperature in the entire space.
2. A CRAC system rating should generally be 1.3 times the projected IT load rating plus any capacity added for redundancy.
A CRAC unit that is too small for the data centre may result in overheating, which could harm equipment and result in downtime. Meanwhile, while CRAC units, unlike air conditioners, can control humidity, if one is too large for the data centre, it may result in condensation or static discharges.
3. Precision air cooling and close control air conditioning are other names for CRAC systems.
Data centres and server rooms’ temperature, humidity, and air distribution are monitored and maintained via computer room air conditioning. CRAC systems do not intend to be cosy. Recall that people engage with comfortable temperatures via comfortable air conditioning. Compared to traditional air conditioning systems, CRAC systems feature superior humidity control mechanisms, higher airflow, and better air filtering.
4. Air is forced over a cooling coil filled with refrigerant in CRAC units as part of the refrigeration cycle that powers them.
A compressor maintains the coldness of the refrigerant in the cooling coil. It loses the heat that is too much as air, water, or a combination of glycol. While modern CRAC devices allow for multiple airflow changes, older units can turn on and off.
