Product Description 1.1 Product Description The Liebert CRV is an air cooled full-featured direct expansion and chilled water Thermal Management ® unit to be installed within a row of high density computing racks in a “hot-aisle-cold-aisle” configuration. Air heated by the room equipment enters the unit from the hot aisle; it is filtered, cooled, conditioned, and subsequently returned to the cold aisle.

Application of Liebert ® 2.5 Temperature sensors The sensor may be placed where desired or left coiled inside the unit. It is recommended that the sen- sor be routed to the front of the heat load for the most accurate temperature reading. In InRow config- uration, the temperature sensor monitors the temperature of the air entering the rack equipment.
Liebert CRV 3.1 Standard features Air cooled models DX COOLING COIL It is constructed of copper tubes and hydrophilic coated aluminium fins. The hy- drophilic coating provides superior water carryover resistance. A stainless steel condensate drain pans are provided. REFRIGERATION SYSTEM Single refrigeration circuit includes a liquid line filter drier, a refrigerant sight glass with moisture indicator, an electronic expansion valve, and a liquid line solenoid valve.

Liebert CRV LOCKING DISCONNECT SWITCH A molded case circuit interrupter disrupts the flow of power to the unit. The electric panel high voltage compartment can only be accessed with the switch in the ‘off’ po- sition. It is located behind the back door for a quick access. 5 PORT ETHERNET SWITCH The unit is equipped with 5 port Ethernet Switch for connection of the units into LAN to enable team work.

Liebert CRV FILTER The optional F5 class (following EN779) filters are two deep pleated 60 mm, located within the cabinet and accessible from the rear of the unit. A filter clog alarm is included as an option. ONE (1) EXTRA COMMON ALARM CONTACT Provides the customer with a total of two sets of nor- mally open (n/o) contacts for remote indication of unit alarms.
Operation Unit operation is completely automatic. The below sequence explains how the unit operates: • The air, sucked in by the continuously operating fans, enters the unit. • The air is immediately filtered. • The TEMPERATURE sensor or HUMITEMP (temperature + rel. humidity) sensor (depends on unit configuration), verifies the state of the inlet air, and relays this information to the control system.
Microprocessor Controls 5.1 iCOM Control Liebert CRV models are controlled by iCOM Medium Board (Fig. 5.a). The control board is housed in the electrical panel and it is connected to the remote display, to be installed in the contain- er/room (connection cable is included). •...
