Data Center Chillers

Data Center Chillers are facilities used to house computer systems and their corresponding . Most common in telecommunications and IT facilities, backup power supplies, environmental controls, security devices, and data communications connections are protected at offsite locations. Data centers originated with the introduction of computers and progressed with adapting technology. They can be private or public. A private data center will exist within a specialized facility that is maintained by the company, or can exist of property owned by the company. A public data center allows for any and all types of user access to the center. Location is not a restriction when public data centers are used.


Immersion Systems

Data centers use two types of immersion systems. Single phase and two phase immersion systems are similar.  Both systems use dielectric coolant. A dielectric coolant is a liquid that is able to transmit electric force but doesn’t use conduction. Mineral oil is considered a dielectric coolant.  The systems are emerged in the dielectric fluid and the hot fluid is pumped to a different location. The difference between single phase and two phase is how the hot fluid is cooled. Single phase immersion liquid doesn’t change, but in two phase it does. In the two phases system, evaporation occurs.

Some data centers don’t use the immersion process and control cooling by air cooled systems, glycol systems, water or chiller water systems. These systems use a coolant to control the temperature and humidity of the data center. The difference between systems is how the coolant is cooled, and what coolant is being used. Below this area will be discussed in detail.
