Claim 0:
1. A cooling system comprising:
a first refrigerant circuit including: a first evaporator coil in thermal communication with an air outtake flow to a heat load, and a first condenser in fluid communication with the first evaporator coil;
a second refrigerant circuit including: a second evaporator coil in thermal communication with an air intake flow from the heat load, and a second condenser in fluid communication with the second evaporator coil, wherein the second evaporator coil is in air flow series with the first evaporator coil such that the air intake flow is coupled to the air outtake flow, and the second condenser is in fluid communication with the first condenser;
a water loop in fluid communication with a free-cooling fluid cooler and the first and second condensers such that water output from the free-cooling fluid cooler flows to the second condenser from the first condenser;
a chiller loop in thermal communication with the water loop and the first and second condensers, the chiller loop including a trim condenser in fluid communication with: the chiller loop at a first trim fluid path of the trim condenser, and the water loop at a second trim fluid path of the trim condenser; and
an air conditioning system evaporator in thermal communication with the first and second condensers, a first evaporator fluid path of the air conditioning system evaporator in fluid communication with the first trim fluid path, and a second evaporator fluid path of the air conditioning system evaporator in fluid communication with the water loop,
wherein the second evaporator fluid path is in fluid communication with the second trim fluid path via the first and second condensers, and
wherein a fluid flowing through the chiller loop and a fluid flowing through the water loop flow in opposite directions through the trim condenser.
