VARISTAR Cooling unit SHX 30 Mode of operation 12366 Fig. 1: Mode of operation of the cooling module (principle) Cooling module Pump *) External recooler *) Enclosure (not included in the scope of supply) The cooling units are positioned between the VARISTAR cabinets in an enclosure. The fans of the cooling unit suck the warm air in at the back and guide it through an air/water heat exchanger.
VARISTAR Cooling unit SHX 30 Air circuit Example "cold aisle containment": The fans of the cooling unit withdraw the heated air from the room and guide it through an air/water heat exchanger. During this process, the thermal energy is transferred to the water circuit.
VARISTAR Cooling unit SHX 30 Control method The fans and the control valve of the water circuit are actuated by a closed loop and open loop control unit. A closed loop control circuit controls the flow of water through the air/water heat exchanger as a function of the air outlet temperature of the cooling module.
VARISTAR Cooling unit SHX 30 Alarms The electronic control system can detect various malfunctions (e.g. cable break of a temperature sensor, temperatures exceeding the limit values) and indicate them via the display or interface. In order to issue a visual alarm, there is an LED (red) above the control unit on the cooling module.
