1. A datacenter comprising:
- a slab comprising a floor of the datacenter;
one or more heat-generating electronic components disposed above the slab;
an air conditioning system comprising;
an air inlet,an evaporative cooling system downstream of and in fluid communication with the air inlet, andan air outlet directing air over the one or more heat-generating electronic components; and
a fluid circulation system that is not in fluid communication with the evaporative cooling system, comprising;
a coil disposed in the air conditioning system upstream of the evaporative cooling system and downstream of the air inlet, anda conduit in fluid communication with the coil and at least partly disposed in the slab.

Abstract
Air conditioning systems and techniques are described that include passing a fluid through a slab. The fluid is cooled in the slab and the cooled fluid is circulated to a coil. The coil is arranged in an airflow such that ambient air passes over the coil, thereby reducing the relative humidity of the ambient air. A control unit may also be provided to selectively operate a pump to control the flow of the fluid through the slab.

6. A system for conditioning air in a room, comprising:
-
an air inlet through which external air enters the system; a ground-bearing slab; an air cooler; and a fluid circulation system upstream of the air cooler comprising; a conduit disposed in the slab, the conduit not being in fluid communication with the air cooler, and a coil disposed in the air inlet and in fluid communication with the conduit. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method of cooling a data center comprising:
-
circulating a coolant through a closed system comprising a conduit disposed in a ground-bearing slab and a coil; passing ambient air entering the data center over the coil to dehumidify the ambient air; exposing the dehumidified air to an evaporative cooling system outputting cooled air, the evaporative cooling system not being in fluid connection with the coil; and directing the cooled air into a space in the data center containing heat-generating components. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
