摘要： A method of detecting loss of refrigerant within a cooling system of the type having a condenser, a refrigerant receiver in fluid communication with the condenser, a sensor configured to detect a level of refrigerant within the receiver, an evaporator in fluid communication with the receiver, and a pump or compressor in fluid communication with the evaporator and the condenser, includes establishing a baseline measurement of refrigerant mass contained in the receiver with the sensor during certain power loads applied to the cooling system, monitoring a mass of refrigerant in the receiver with the sensor at a certain power load applied to the cooling system, and identifying whether the monitored mass of refrigerant is less than the baseline measurement of refrigerant mass over a predetermined period of time. Systems for detecting loss of refrigerant are further disclosed.

摘要： 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.

摘要： The present invention relates to systems and methods for controlling head pressure in a vapor compression system, e.g. in a precision air conditioning system. One embodiment of the invention provides a method for regulating working fluid flow in a vapor compression system including a compressor. The method includes: providing a controller; receiving signals at the controller representative of a monitored discharge pressure in a discharge line of the compressor; and using the controller to provide a control signal to an actuator that controls a flow control valve that, in turn, controls working fluid flow into the system, the control signal being responsive at least in part to a difference between a set point pressure and the monitored discharge pressure.
