new data center heat removal systems and methods allow a combination of active and passive thermal processes for removing heat from and cooling air in data center environments . systems and methods include a data center heat removal system including an adjustable thermal feed cold air intake system , a distribution system for cold and warm air including one or more hot aisles and one or more cold aisles , and a convection system to draw cool air through data center equipment using a naturally - occurring convection processes to expel hot air . misters , cooling elements , and / or freezer boxes may further cool the intake of air . a controller is programmed to efficiently manage and control the climate within a data center to minimize the use for energy for air distribution and cooling .
