Systems and methods for controlling load dynamics in a pumped refrigerant cooling system

Abstract

A pumped refrigerant cooling system for use in a row of equipment racks is configured to contain electronic equipment. The system includes a communication network and a refrigerant distribution unit in fluid communication with a chilled refrigerant supply and a heated refrigerant return. A cooling module is in fluid communication with the refrigerant distribution unit by a supply line and a return line. The cooling module is coupled to the communication network, and includes an evaporator and a fan configured to direct air over the evaporator. A sensor package is configured to monitor temperature and pressure reference points provided in the pumped refrigerant cooling system and the equipment racks. The system further includes a controller forming part of the cooling module and coupled to the communication network and the sensor package. The controller, based on information obtained from the sensor package, is configured to manipulate the flow of refrigerant through the evaporator by controlling the delivery of refrigerant to the evaporator and is configured to manipulate the flow of air over the evaporator by controlling the speed of the fan.
