摘要

The cooling systems and methods of the present disclosure relate to cooling electronic equipment in data centers or any other applications that have high heat rejection temperature and high sensible heat ratio.

主权项

1. A cooling system comprising:
a first evaporator coil in thermal communication with an air intake flow to a heat load; a first liquid refrigerant distribution unit in fluid communication with the first evaporator coil to form a first fluid circuit; a second evaporator coil disposed in series with the first evaporator coil in the air intake flow and in thermal communication with the air intake flow to the heat load; a second liquid refrigerant distribution unit in fluid communication with the second evaporator coil to form a second fluid circuit; a water circuit in thermal communication with the first fluid circuit and second fluid circuit; and a chiller circuit in thermal communication with the water circuit.
