ABSTRACT:
The present invention provides an indoor unit in air conditioner, including two heat exchangers, a connection pipe connecting the heat exchangers, first means for guiding refrigerant flow, and second means provided to the connection pipe. The two heat exchangers, i.e., first and second heat exchangers, have one ends connected to first and second pipelines connected to parts outside of the indoor unit, for an example, a compressor or an outdoor expansion device. The first means selectively guides the refrigerant introduced thereto through the first or second pipeline to be discharged through the second or the first pipeline after being passed through both, or either of the first and second heat exchangers. The second means is provided to the connection pipe so that the refrigerant transferred from one of the first and second heat exchanger to the other one of the first and second heat exchanger is passed in an original state or in an expanded state.
