Problems solved by technology

Due to the lowered surface temperature, on the surface of the heat-exchanger of the outdoor unit, frost is generated so that the efficiency of the heat-exchanger of the outdoor unit is deteriorated.
Thus, when the temperature of the outdoor heat-exchanger is

Abstract

A defrosting method of an air conditioner is disclosed. The air conditioner has an indoor unit having an indoor heat-exchanger, an indoor blower fan, an auxiliary heater, an outdoor unit having an outdoor heat-exchanger, a compressor, an expansion device, and an outdoor blower fan, and a four-way valve to selectively switch a circulation direction of a refrigerant between the indoor unit and the outdoor unit such that the air conditioner is operated in a heating cycle when the four-way valve is turned off and the air conditioner is operated in a refrigerating cycle when the four-way valve is turned on. The defrosting method is selectively determined according to the number of the heating cycles of the air conditioner.

Description

[0001]This application claims the benefit of Korean Patent Application No. 10-2005-0127973, filed on Dec. 22, 2005, which is hereby incorporated by reference as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a defrosting method of an air conditioner, and more particularly, to a defrosting method of an air conditioner of effectively removing frost generated in pipes of an outdoor heat-exchanger by changing defrosting operation in a heating cycle.[0004]2. Discussion of the Related Art[0005]Generally, an air conditioner has a refrigerating cycle in which refrigerant circulates in the order of compression, condensing, expansion, and evaporation to transfer heat. Due to this refrigerating cycle, the air conditioner works in a refrigerating cycle in which indoor heat is discharged to the outdoor in summer season and serves as a heat pump in which the refrigerant circulates in a direction opposite to the direction ...
