为解决传统多联机无新风、空气品质差的问题,在实际工程中通常采用多联机与新风机组2套系统,但这两者通常是独立控制。为充分实现多联机和热回收新风机组的协同控制,研发了多联机与新风机组联合运行的新风多联机系统,以降低系统能耗,提高室内环境的舒适性和空气品质。基于多联机全工况性能模型和新排风热回收机组的特性,采用模拟分析方法,探讨常规多联机系统与3种新风多联机系统在南京和北京住宅建筑中的节能效果。研究表明:相比于常规家用多联机新风系统,采用定风量新排风热回收机组可显著降低系统运行能耗,全年节能率在南京和北京分别达到20.7%和30.6%,且节能效果与气候寒冷程度呈正相关;在制热工况下,系统优先采用热回收模式并将新风量控制在最小水平;在制冷工况下,通过引入旁通支路并结合变风量控制策略可进一步提升节能性能,相较于基准方案1,南京和北京的制冷季节节能率分别提高了2.77%和15.31%。
To address the issues of poor air quality and the lack of fresh air in traditional variable refrigerant flow (VRF) systems, VRF systems and fresh air units are commonly used in combination in practical engineering applications. However, these systems are typically controlled independently. To achieve coordinated operation between VRF systems and heat-recovery fresh-air units, a new integrated VRF fresh-air system was developed, with the aim of reducing system energy consumption and improving indoor comfort and air quality. Based on the full-condition performance model of the VRF system and the characteristics of the heat-recovery unit, simulation analyses were conducted to evaluate the energy-saving effects of conventional VRF systems and of three types of integrated VRF fresh-air systems in residential buildings in Nanjing and Beijing. The results indicate that, compared with conventional residential VRF fresh-air systems, the system equipped with a constant air volume heat-recovery unit significantly reduced the operational energy consumption, achieving annual energy savings of 20.7% and 30.6% in Nanjing and Beijing, respectively. The energy-saving performance was positively correlated with the severity of cold-climate conditions. During the heating season, the new integrated system prioritizes the use of the heat-recovery mode and minimizes the fresh air volume. During the cooling season, the energy-saving performance can be further improved by introducing a bypass branch and combining it with a variable air-volume control strategy. Compared to the primary baseline system, the combined VRF fresh-air system achieved cooling-season energy-saving rates of 2.77% and 15.31% for Nanjing and Beijing, respectively.
