    摘要： A sealed type electric compressor includes a sealed vessel (51,52); a compressor unit (11); a motor (12); and a motor driving module (13) having a power unit (131) and a control unit (132), for operating the motor (12), wherein the compressor unit (11), the motor (12) and the motor driving module (13) are accommodated in the sealed vessel. The sealed type electric compressor allows the size of an outdoor unit to be reduced by accommodating the motor driving unit in the sealed vessel and reliably performs a signal transmitting/receiving operation to/from an exterior.

    摘要： A monitoring seal system (200) comprises a seal housing (202), a seal assembly (210), a temperature sensor (212) and a controller. The seal assembly sealingly engages a rotary shaft (208) to prevent fluid leakage between the shaft and the housing. The seal assembly has at least one seal. The seal has a primary ring (228) and a mating ring (226). The temperature sensor senses the temperature in the vicinity of the seal. The controller determines whether an upset condition has occured based on at least the temperature in the vicinity of the seal.

    摘要： A conventional control system for an electrical heating or cooling apparatus has a thermostat 103 which controls a compressor 102 to cycle on and off. For peak load periods, a load shedding signal is sent out by the power company which controls a duty cycler 100 via a radio receiver 101. The duty cycler 100 sets reference ON and OFF times from the last thermostat cycle, and thereupon over-rides the thermostat by preventing the ON time of each cycle from exceeding, and the OFF time of each cycle from being less than, the reference ON and OFF times. To prevent tampering, the reference ON and OFF times may be restricted by preset maximum and minimum values respectively, and reset during a load shed period if the thermostat ON and OFF times fall short of or exceed the reference times respectively. Alternatively, the reference times may be taken from the last thermostat cycle whose times are within preset limits.
