COOLING SYSTEM WITH EVAPORATORS DISTRIBUTED IN SERIES

摘要

A stem (220) and method (300) for cooling a room (210) configured to house a plurality of computer systems (212). A plurality of evaporator units (222) are arranged in series and are configured to receive air from the room and to deliver air to the room. The evaporator units are supplied with refrigerant operable to cool the received air in the evaporator units. At least one of the temperature of the refrigerant supplied to the evaporator units and the air delivery to the room may be controlled in response to temperature sensed at one or more locations in the room.
