Abstract (en)
[origin: WO2007046791A1] There is provided a refrigerant system (100) including a plurality of components (120, 125, 140, 145) for regulating operational parameters of the refrigerant system (100), at least one transducer (135) connected to the refrigerant system (100) for monitoring the operational parameters of the refrigerant system (100), and a controller (150). The controller (150) is remotely connected to the at least one transducer (135) and to at least one component (120, 125, 140, 145) of the plurality of components (120, 125, 140, 145) for at least periodically receiving parameter information from the at least one transducer (135) to monitor the operational parameters and determine, based on variations in at least one parameter of the operational parameters, whether a condition exists in the refrigerant system (100) that requires corrective action. The corrective action may include moving the refrigerant system (100) to a lighter mode of operation by unloading or even shutting down some of the refrigerant system components (120, 125, 140, 145). There is also provided a method for monitoring the refrigerant system (100).
