Claim 6:
7. 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 via 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 including first and second trim fluid paths;
an air conditioning system evaporator in thermal communication with the first and second condensers, the air conditioning system evaporator including first and second evaporator fluid paths in fluid communication with each other; and
a compressor in fluid communication with a fluid output of the first evaporator fluid path and a fluid input of the first trim fluid path,

wherein the first refrigerant circuit includes the first condenser, which includes first and second condenser fluid paths, a first fluid receiver in fluid communication with the first condenser fluid path, and a first refrigerant pump in fluid communication with the first fluid receiver,
wherein the second condenser fluid path is in fluid communication with the second evaporator fluid path,
wherein the second refrigerant circuit includes: the second condenser, which includes a third condenser fluid path and a fourth condenser fluid path, a second fluid receiver in fluid communication with the third condenser fluid path, and a second refrigerant pump in fluid communication with the second fluid receiver,
wherein the fourth condenser fluid path is in fluid communication with the second condenser fluid path and the water loop,
wherein the water loop is in fluid communication with the second trim fluid path,
wherein water flows through the air conditioning system evaporator to the trim condenser 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.
