摘要： An induction motor having a rotor and a stator is protected during running overloads by connecting the motor to an overload protection relay that can be tripped to interrupt power to the motor in the event of an overload, tracking the stator winding temperature of the motor during running overloads with a hybrid thermal model by online adjustment in the hybrid thermal model, and tripping the overload protection relay in response to a predetermined running overload condition represented by the tracked stator winding temperature. In one embodiment of the invention, the stator winding temperature is tracked by use of an online hybrid thermal model that uses the resistance of the rotor as an indicator of rotor temperature and thus of the thermal operating conditions of the motor. The hybrid thermal model incorporates rotor losses and heat transfer between the rotor and the stator, and approximates the thermal characteristics of the rotor and stator.

摘要： A system and method of measuring atmospheric parameters in an enclosed space using instrumental objects carrying measurement sensors. The objects travel through the space along flight paths. As the objects travel through the space, attached measurement sensors measure atmospheric parameters and store the measurements to a memory. The devices periodically upload the measured atmospheric parameters to a controller circuit. By using self-propelled objects to carry measurement sensors, the system and method disclosed herein allow for periodically sampling atmospheric parameters in the interior of a closed space at a number of locations greater than the number of measurement devices employed. With data points taken from various locations within a volume of a closed space, the system and method can realize a more efficient utilization of energy by adjusting mechanical controls of an HVAC system or a ventilation system, for example.

摘要： A method of automatically detecting an anomalous condition relative to a nominal operating condition in a vapor compression system. An expected input power function in the form of a hyperplane is calculated based on three temperature readings: an intake temperature from an intake area of the condenser unit, a return temperature from an intake area of an evaporator unit, and a supply temperature from a supply output area of the evaporator unit. The function produces an estimate of the expected input power consumed by the compressor unit, and this expected input power is compared with an actual input power measured from the compressor unit. If the expected input power deviates from the measured input power by more than a predetermined tolerance, an indication is stored and communicated that an anomalous condition, such as a refrigerant loss, condenser unit fouling, or a malfunctioning fan, exists in the vapor compression system.
