摘要： PROBLEM TO BE SOLVED: To precisely judge a clogged state of a filter by making an integrated value per unit time large until a predetermined period of time elapses from the start of rotation of an indoor fan, and making the integrated value small after the predetermined period of time has elapsed. SOLUTION: A multiple control unit(MCU) 33 for an indoor machine 30 integrates a time of revolution of an indoor fan 38, and estimates, when the integrated time exceeds a predetermined threshold, that a filter 48 is in a clogged state. An integrated value per unit time is made large until a predetermined period of time, for example, one hour elapses from a time when the indoor fan 38 starts to rotate. After the predetermined period of time has elapsed, the integrated value is made small. In this manner, the integrated value for estimation of clogging of the filter 48 is changed in accordance with a period of time, which elapses from the start of rotation of the indoor fan 38. Accordingly, it is possible to precisely judge a clogged state of the filter 48 in view of an amount of dust adhering to the filter 48, which varies depending upon a period of time elapsed from the start of rotation of the indoor fan 38.

摘要： PURPOSE: To contrive an improvement in effciency through comfortable air conditioning by enabling operation having a less variation in a refrigeration cycle, by so constituting that respective varying speeds of numbers of revolutions of a compressor at the time of ascending a number of revolutions and descending the same are enabled to switch over in a plurality of kinds, which are switched over based on a detected signal of a loaded state.
CONSTITUTION: Simultaneously with starting of a refrigeration cycle a number of revolutions (f) is ascended, through which discharge pressure P is ascended. In this instance, although the number of revolutions is controlled by a difference between the room temperature of a room to be air-conditioned and a set temperature, a variation speed in ascending the number of revolutions (f) is made large as the temperature difference is large at the time of starting operation and the room temperature is made to arrive at the set temperature rapidly. The number of revolutions (f) is made into the maximum number of revolutions f
1 when the discharge pressure P is arrived at the minimum set pressure P
o , which is maintained under that state. Meanwhile, the discharge pressure P is ascended and operation within a range of appropriate pressure is done. When a matter that the discharge pressure P ascending is exceeded the maximum set temperature P
1 is sensed by a pressure sensor 14, a sensed signal is sent out to an outdoor unit control circuit 9 by the sensor 14, through which a signal for descending the number of revolutions is sent out to a compressor 11 from an inverter circuit 10.

摘要： PURPOSE:To reduce high and low temperature release controls and to perform comfortable air conditioning control by providing a controller for varying the input current limit value of an inverter in response to the number of operation of indoor units. CONSTITUTION:In a multi-air conditioner 1, a plurality of indoor units 5 are connected to an outdoor unit 4 having a capacity variable compressor driven by an inverter 2. A temperature sensor 6 and a temperature setter 7 are provided in each unit 5. A controller 9 obtains a whole air conditioning load from the difference between the sensor 6 and the setter 7 of the unit 5, and outputs an operating command frequency to the inverter 2. Particularly, the controller 9 sets the input current limit value of the inverter 2 in response to the number of the units 5, compares the detected value detected by an input current detector 10 with the input current limit value to vary the output frequency of the inverter 2. Accordingly, compressor capacity becomes responsive to the number of the unit to reduce high or low temperature release control, thereby conducting comfortable air conditioning control.

摘要： PURPOSE:To always obtain a suitable output voltage without influence of the variation of an input voltage by detecting the variation in the input voltage from a power source, and switching the frequency-voltage characteristics of the output of an inverter apparatus in response to the detected result. CONSTITUTION:An input voltage from a power source 1 is reduced by a transformer 40, rectified by a diode 41 and a smoothing condenser 42, and applied to a series circuit of resistors 43, 44. The voltage across the resistor 44 is varied in response to an input voltage, the voltage across the resistor is converted by an A/D converter 45 into a digital signal to be supplied to a microcomputer 24, which detects the variation in the input voltage. The microcomputer 24 selects the frequency-voltage (V/F) characteristic stored in advance in an internal memory with the detected input voltage as a parameter, and controls an inverter waveform composite circuit 26 on the basis of the selected V/F characteristic.

摘要： PURPOSE:To prevent an overcurrent from flowing to an inverter circuit by controlling the release of lowering the rotating speed of a compressor when either one of the input side and the output side of the inverter circuit exceeds the upper limit current value. CONSTITUTION:When the fact that either one of the current values of the input side and the output side of an inverter 10 exceeds the upper limit current value during the operation of a compressor 11 is detected by the first and second sensors 21, 22, a release control is performed to lower the rotating speed of a compressor 11. Therefore, if an overcurrent flows at the output side of the inverter 10 or the compressor is operated in a high speed range when the compressor 11 is operated in a low speed range, the overcurrent is effectively prevented from flowing at the input side of the inverter 10.
