| 摘要 |
<p>The invention relates to an expansion circuit (7) comprising a working medium and a decompression unit (3) for converting thermal energy of a combustion engine (10) into electrical energy by expanding the working medium. The decompression unit (3) is part of an air-conditioning circuit (2) as a compressor for compressing a working medium. Therefore, the decompression unit (3) can be used both as a generator, driven by the expanding working medium for generating electrical energy in the expansion circuit (7), and, as a compressor, driven electrically, for the compression of a working medium in the air-conditioning circuit (2). Using the compressor of the air-coditioning system (2) as a decompressor unit (3) in the expansion circuit (7), and as a compressor in the air conditioning system (2) is less costly compared to providing both a decompression unit (3) and a compressor.</p> |
