| 摘要 |
The invention relates to a novel structured air-conditioner with both cooling and warming functions, comprising a compressor, an out-door heat exchanger, an in-door heat exchanger and a four-way change-over valve, characterized in that it further comprises a parallel capillary device, a parallel expansion valve device or a combination of parallel capillary and expanding valve connected with the in-door and the out-door heat exchanger respectively. Said parallel capillary device, said parallel expansion valve device or the combination comprises a two-position three-way change-over valve or one-way valve with opposite direction of leading through and two groups of parallel capillary tube, two groups of parallel expanding valve, parallel capillary tube and expanding valve or a combination of two groups of series capillary tube and expansion valve. The invention provides a new generation of air-conditioner with both cooling and warming functions having novel structure, excellent performance, low energy consume and high efficiency.
