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 (e.g., temperature, humidity, air flow, pressure, air quality, etc.) within a data center to minimize the use for energy for air distribution and cooling.
