Abstract
The present invention relates to a method for controlling an air conditioner, in which operation time periods of an outdoor unit is integrated, to determined a time point when an oil recovery operation is performed, and performing the oil recovery operation only when a summed rates, or a number of indoor units accessed with communication is higher than a value preset at a control unit.
Claims14
A method for controlling a multi-type air conditioner comprising the step of:
- a control unit integrating operation time periods of an outdoor unit;
- the control unit attempting to access to all indoor units with communication if it is determined that the integrated time period of the outdoor unit reaches to an integrated time period preset at the control unit;
- summing maximum operation rates of the indoor units accessed with the communication;
- determining whether the summed operation rate is higher than a rate preset at the control unit;
- and
- performing an oil recovery operation of the indoor units only when the summed rate is higher than the preset rate.
