    摘要:

    对地源热泵+水冷多联机温湿度独立调节系统和地源热泵+风冷多联机温湿度独立调节系统2种方案的间歇运行方式和连续运行方式的综合能效比进行分析与计算,结果表明:潜热和新风负荷越小,系统的综合能效比越高,随着潜热和新风负荷的增大,系统的综合能效比下降;地源热泵+水冷多联机温湿度独立调节系统间歇运行方式比连续运行方式的综合能效比更高;在实际工程中,常见的地源热泵+水冷多联机温湿度独立调节系统比地源热泵+风冷多联机温湿度独立调节系统的综合能效比高近1.4倍;地源热泵+风冷多联机温湿度独立调节系统中,当潜热和新风负荷超过40%后,不管是间歇运行方式还是连续运行方式,其综合能效比都较接近,说明该系统对运行方式要求不高。

    Abstract:

    Analyzes and calculates the comprehensive energy ratios of intermittent operating mode and continuous operating mode for independent temperature and humidity control systems of GSHP - water cooling VRV and GSHP - wind cooling VRV. The results show that: The smaller the latent heat and fresh air load, the higher the integrated energy efficiency ratio will be, with the latent heat and fresh air load increasing, the system integrated energy efficiency ratio decreased. The integrated energy efficiency ratio of intermittent operating mode is higher than that of continuous operating mode for GSHP-water cooling VRV system. In practical engineering, the integrated energy efficiency ratio of common GSHP - water cooling VRV independent control system is 1.4 times higher than that of GSHP- wind cooling VRV system. When the latent heat and fresh air load is over 40% in GSHP-wind cooling RVR system, the integrated energy efficiency ratios of intermittent operating mode and continuous operating mode are similar, indicating that the system has little demand in operating modes.
