| 摘要 |
The present invention relates to a refrigerant system comprising a compressor, an outdoor heat exchanger, an expansion part, and an indoor heat exchanger. The refrigerant system includes a four-way valve for controlling the flowing direction of the refrigerant discharged from the compressor; an accumulator arranged on the inlet side of the compressor to separate refrigerant vapor from the refrigerant flowing into the compressor; and a bypass pipe for allowing refrigerant which has passed through the indoor heat exchanger to flow into the accumulator. Therefore, the refrigerant system makes refrigerant which has passed through the indoor heat exchanger bypass the four-way valve by flowing in the bypass pipe The present invention maximizes cooling efficiency by minimizing low pressure loss of the refrigerant which has passed through the indoor heat exchanger in the cooling operation of the refrigerant system. |
