How is the temperature/capacity controlled in the pumped refrigerant version of the Liebert XD system?
Since the Liebert XDH (and XDO and XDV) are using the pumped refrigerant technology, they have built-in automatic capacity/temperature control. The self-regulating capacity function is achieved through the phase-changing of the fluid as it passes through the cooling module. If there is a low heat load and low entering air temperature to the cooling module, the cooling capacity of the module goes down. At high heat load and higher entering air temperature to the cooling module, the capacity goes up. In addition, the controls in the Pumping Unit, Liebert XDP (and the refrigerant chiller, Liebert XDC), that supplies pumped refrigerant to the modules can be set so the fluid temperature to the modules is never below a value decided by the user.
