An air conditioner includes: an outdoor unit; a plurality of indoor units respectively including indoor heat exchangers; expansion valves respectively provided to the plurality of indoor units, the expansion valves being configured to adjust flow rates of a refrigerant in the indoor heat exchangers; and a controller for executing a refrigerant amount balance control for adjusting opening degrees of the expansion valves so that operation state amounts, with which the indoor heat exchangers exert heat exchange amounts, of the plurality of indoor units become equal to each other.

A method of controlling a computer processing component of a depilatory wax heating apparatus to perform operations including at least determining when to activate based on one or more first parameters; turning on a heating element based on a determination of when to activate; controlling temperature of the heating element based on one or more second parameters; and deactivating the heating element based on one or more third parameters.
