An air-con ECU (10) consists of one type of a control unit producing and transmitting a signal to engage or disengage an electromagnetic clutch (44) of an engine-driven compressor (40), on the basis of environmental parameter signals transmitted from environmental parameter detection means (20 to 25), and also retransmitting the environmental parameter signals. An electromagnetic portion of the electromagnetic clutch (44) engages or disengages the electromagnetic clutch of the engine-driven compressor by selectively receiving the signal to engage or disengage the electromagnetic clutch (clutch engage/disengage signal) transmitted from the air-con ECU, and an electric motor control portion (34) of an electric compressor (30) controls rotation of an electric motor of the electric compressor by selectively receiving the environmental parameter signals (various sensor values) transmitted from the air-con ECU.

An air conditioner has a dust catch filter interposed between an inlet and a heat exchanger, a cleaning unit 5 for removing dust caught by the filter, and filter driver 18 for reciprocally driving the filter with respect to the cleaning unit 5. The cleaning unit 5 has a dust box 21 having a cleaning brush for removing dust caught on the surface of the filter and a filter hold plate that is attached to the dust box 21 and that holds a rear surface of the filter. The air conditioner is provided with cleaning brush driver 20 that draws the cleaning brush from the dust box 21 and brings the cleaning brush into contact with the filter during cleaning of the filter and that separates the cleaning brush from the filter and puts the cleaning brush in the dust box 21 when the filter is not cleaned.

An object of the invention is to provide a monitoring device that can be mounted in a window or a door in which because the window is often opened or closed by the user, if the monitoring device is installed on the window, the user must perform an operation of releasing the monitoring device, every time of opening or closing the window. An intrusion detecting terminal unit (13) having an opening/closing sensor is disposed on the window or door, a mat (16) containing a piezoelectric sensor (15) is disposed near under the window, and each of the intrusion detecting terminal unit (13) with the opening/closing sensor and the intrusion detecting terminal unit (15a) with the piezoelectric sensor comprises data communication means for transmitting or receiving data. In case of the intrusion, the intrusion detecting terminal unit (15a) under the window detects the intruder, and then if the intruder tries to open the window, the intruder is judged. However, when the user opens the window, the intrusion detecting terminal unit (15a) does not make the detection, and the intrusion detecting terminal unit (13) alone detects the opening of the window, whereby the user does not need to release the monitoring device every time of opening the window.

A temperature sensor is provided in the vicinity of a power semiconductor element whose temperature becomes highest among a plurality of power semiconductor elements and control of the number of revolutions of a motor is performed on the basis of temperatures detected by the temperature sensor, whereby it is possible to change the number of revolutions of the motor by using a temperature in the vicinity of a power semiconductor element in a position under the worst temperature conditions as a reference, and it becomes possible to positively protect an inverter circuit without the need for a plurality of temperature sensors.
摘要:
A method for controlling an electric compressor into which an inverter for controlling an electric motor as a drive source is integrally incorporated. The method is characterized by comprising the steps of acquiring the temperature of an accessory of the inverter, when the acquired temperature becomes or is already equal to or higher than the maximum rated temperature of the accessory, calculating the value of a current which can flow at the acquired temperature and restrictively controlling the rotational speed of the electric compressor such that the input current becomes equal to or less than the value of the current which can flow, and when the temperature of the accessory becomes lower than the maximum rated temperature, releasing the restrictive control. The method for controlling the electric compressor can prevent a malfunction of the accessory even in use under a high-temperature environment while preventing increase in the cost and size of the electric compressor by preventing an increase in the size of the accessory of the inverter.
