Computer rooms require precise and adaptable temperature control for several reasons:
Need for cooling. Data centers have a dense heat load, generally 10 to 30 times the heat density of normal offices.
Cooling must be delivered where needed. The heat load varies across the area of the computer room. To achieve a balanced psychrometric profile, the air conditioning system must address the needs of particular heat-producing equipment.
Data centers need precise cooling. Electronic equipment radiates a drier heat than the human body. Therefore, precision data center cooling systems require a higher sensible heat ratio (SHR) than office areas. Ideally, the cooling system should have an SHR of 1:1 (100 percent sensible ...
