Computer room air conditioners (CRAC) are large air conditioning units used to remove large amounts of heat from the data center and return large amounts of cold air back to the data center.
The main service targets are computers, providing stable and reliable IDC for the computer room to detect the operating temperature, relative humidity and air cleanliness of the computer room.
It has the characteristics of high sensible heat ratio, high energy efficiency ratio, high reliability and high precision.
CRAC Refrigeration Cycling System
The refrigerant temperature in the evaporator is low. The high-temperature hot air from the server drawn by the indoor fan exchanges heat with the evaporator, becoming low-temperature air suitable for the server entrance. The heat-absorbing refrigerant is compressed The compressor is discharged to the outdoor condenser to dissipate the absorbed heat to the environment. The heat-dissipated refrigerant returns to the indoor unit and becomes low-temperature refrigerant through the throttling effect of the expansion valve, which continues to absorb the hot air from the service. , thereby completing the CRAC refrigeration cycle.
