ABSTRACT:
The present invention relates to the cooling and heating dual-purpose air conditioner, and more particularly to the heat pump type cooling and heating dual-purpose air conditioner wherein the stand-by control is performed in order to prevent the viscosity increases caused by the lubricating oil freeze in the compressor occurring at the initial cooling operation stage and therefore the smooth drive of a compressor in an air conditioner is performed by the preventing of the lubricating oil freeze.
