对组成土壤源热泵系统的3个回路以及整个系统的制冷和制热工况进行了全面的分析,分别给出了它们的损失、效率、损率、损系数以及热力学完善度的表达式。结果表明:在对系统进行分析时,必须将这几个指标结合起来使用。在整个系统中,损率最大的部件是压缩机,而效率与热力学完善度最低的却是土壤热交换器。因此,压缩机和土壤热交换器是整个系统改进的首要对象。 A comprehensive analysis of the cooling and heating conditions of the three circuits that make up the GSHP system and the whole system are given respectively and their loss, efficiency, loss rate, loss coefficient and thermodynamic perfection are given Expression. The results show that: in the analysis of the system, these indicators must be used together. Throughout the system, the most expensive component is the compressor, while the lowest efficiency and thermodynamics is the soil heat exchanger. Therefore, compressors and soil heat exchangers are the primary targets of overall system improvement.
