KR950003747A - Air conditioner - Google Patents

Abstract

The present invention relates to an air conditioner capable of achieving safety of a refrigeration cycle and discharge temperature, wherein the air conditioner of the present invention is repeated with repeat discrimination means (26) for discriminating repetition of other frequencies based on a change in frequency command. And a frequency adjusting means (25) (27) (28) for selecting an intermediate frequency between two repeated frequencies in response to the frequency command and outputting it as a driving frequency of the compressor when repetition of another frequency is discriminated by the discriminating means. It is characterized by being.

Claims (5)

In the air conditioner which controls the drive frequency of the compressor in a refrigerating cycle based on the frequency command from the indoor unit which commands a specific frequency among the frequencies predetermined in step shape according to the difference between room temperature and setting room temperature, the said frequency command changes A repeating discrimination means for discriminating the repetition of another frequency based on the basis, and when the repetition of another frequency is determined by the repeating discriminating means, selecting an intermediate frequency between two frequencies repeated in response to the frequency command to drive the compressor An air conditioner comprising a frequency adjusting means for outputting as a frequency. The air conditioner according to claim 1, wherein the repetition discriminating means discriminates repetition when two frequency commands are output three times alternately. In the air conditioner which controls the operation frequency of the compressor in a refrigeration cycle based on the frequency command from the indoor unit which commands a specific frequency among the frequencies predetermined in step according to the difference between room temperature and setting room temperature, the said frequency command changes a fluctuation. A repetition discrimination means for discriminating repetition of different frequencies based on the basis, and when the repetition of different frequencies is discriminated by the repetition discrimination means, the two frequencies repeated in response to the frequency command are divided into a plurality of unit division frequency widths. And a frequency adjusting means for selecting a frequency focused by the unit division frequency width toward an intermediate frequency between two repeated frequencies in response to a vertical change of a frequency command and outputting the frequency as an operating frequency of the compressor. group. 4. The air conditioner according to claim 3, wherein the frequency adjusting means determines the number of divisions when dividing the two frequencies into unit division frequency widths according to the repeated two frequency differences. 5. The apparatus according to any one of claims 1 to 4, further comprising second frequency adjusting means for outputting an intermediate frequency circumventing the forbidden frequency when the frequency selected by said frequency adjusting means corresponds to a predetermined prohibition frequency. Air conditioner. ※ Note: The disclosure is based on the initial application.
