摘要： A system for monitoring a remote refrigeration system includes a plurality of sensors that monitor parameters of components of the refrigeration system and a communication network that transfers signals generated by each of the plurality of sensors. A management center receives the signals from the communication network and processes the signals to determine an operating condition of at least one of the components. The management center generates an alarm based on the operating condition.

摘要： Components for HVAC systems used in hybrid and fuel cell vehicles are mounted in modular configuration on a frame with air conditioning components connected to one another by metal pipes welded to the components. An alternating current motor, integral with a compressor, is driven by 310 volt alternating current from an inverter, which inverter converts 310 volt direct current that is used to power the vehicle. PTC heaters in fluid communication with an evaporator employed by the air condition system are directly energized by the 310 volt direct current. The modular system is mounted directly on the chassis of the vehicle, facilitative assembly of the vehicle, and is readily removable as a unit from the chassis for repair or replacement.

摘要： A compressor torque estimate device is used for a variable displacement compressor whose displacement is variable based on a compressor control signal for estimating a compressor torque of the compressor. The compressor torque estimate device includes a torque calculator and a corrector. The torque calculator calculates a torque required for driving the compressor based on the compressor control signal, thereby obtaining a calculated torque. The corrector corrects the calculated torque by a procedure of first-order lag, thereby obtaining a corrected torque. The corrector also estimates the corrected torque to be the compressor torque.

摘要： Disclosed herein is an air conditioning unit and method of operating the same. The air conditioning unit has a power level control unit (6) for controlling the level of power supplied to a motor (2a) of a compressor. The power level control unit (6) is comprised of a first supplying unit (6a) for supplying first level power to the compressor motor (2a), and a second supplying unit (6b) for supplying second level power to the compressor motor (2a). If an operation cycle of the compressor corresponds to a loading operation, the power level control unit (6) supplies first level power for compressing a cooling agent through the first supplying unit (6a). Further, if an operation cycle of the compressor corresponds to an unloading operation, the power level control unit (6) supplies second level power less than the first level power through the second supplying unit (6b). Therefore, the present invention is advantageous in that it can reduce undesirable power consumption caused by the compressor motor during the unloading operation.
