Abstract
A method of starting a compressor of an air conditioner involves raising the operation frequency of the compressor from zero to a target operation frequency in different patterns (stages), depending upon (1) whether the air conditioner is being operated in a heating mode or a cooling mode, and (2) whether, during a heating mode, the target operation frequency is in a high range, a medium range, or a low range. During a heating mode at either of the high and medium target frequency ranges, the compressor frequency is increased and decreased on its way to reaching the target operation frequency.
Claims8
A control method for starting a compressor of an air conditioner capable of selective operation in heating and cooling modes, said method comprising the steps of:
- A. determining which of the cooling and heating mode modes is selected;
- B. establishing a target operation frequency for the compressor associated with the selected mode;
- C. sensing an outdoor temperature;
- D. comparing outdoor temperature to a reference temperature associated with the selected mode;
- E. determining a rate of increase of operation frequency in accordance with the comparison results of step D;
- F. starting the compressor by applying an operation frequency thereto and increasing said operation frequency from zero at said determined rate of increase;
- and
- G. bringing the operation frequency to said target operation frequency and thereafter operating the compressor at said target operation frequency.
