Abstract: A method of retrofitting a computer room air conditioner having a direct expansion refrigeration circuit to increase a maximum temperature delta of the computer room air conditioner includes adding an upstream cooling circuit that is a pumped refrigerant cooling circuit having a cooling coil disposed upstream of a cooling coil of the direct expansion refrigeration circuit. Air to be cooled is passed in serial fashion across the cooling coil of the upstream cooling circuit and then the cooling coil of the direct expansion refrigeration circuit. The upstream cooling circuit is controlled to cool the air flowing across the cooling coil of the upstream cooling circuit to provide only sensible cooling and so that a temperature of the upstream cooling coil is always above a dewpoint of the air flowing across the upstream cooling coil. The direction direct expansion refrigeration circuit is controlled to provide any latent cooling that is needed.

Abstract: A cooling system has a cabinet and a plurality of separate cooling stages including an upstream cooling stage and a downstream cooling stage. At least the upstream cooling state is a variable capacity cooling stage. Each cooling stage has a cooling circuit. Evaporators of the cooling circuits are arranged in the cabinet so that air passes over them in serial fashion. A controller when a Call for Cooling first reaches a point where cooling is needed, operating the upstream cooling circuit to provide cooling and not the downstream cooling circuit. When the Call for Cooling has increased to a second point, the controller additionally operates the downstream cooling circuit to provide cooling. The cooling capacity at which the upstream cooling circuit is being operated is less than its full capacity when the Call for Cooling reaches the second point.

Abstract: A computer room air conditioner (“CRAC”) has a cabinet having an air inlet through which return air from an area is drawn and an air outlet through which air cooled by the CRAC is exhausted. An air moving unit is disposed in the cabinet as are a plurality of cooling coils, which are in separate cooling circuits. The cooling coils are arranged so that the air passes through the cooling coils in serial fashion, that is, first through an upstream cooling coil and then through a downstream cooling cool. The upstream cooling coil acts as a pre-cooler to the subsequent downstream cooling coil. The CRAC includes a controller that controls the cooling provided by the cooling circuits. The controller controls the cooling provided by the upstream cooling circuit so that when it is being used to provide cooling, it provides only sensible cooling.
