摘要:以南京某住宅项目为例,介绍了该项目复合式地源热泵系统、空调水系统、新风系统、空调末端、温湿度及防结露控制。该空调系统采用集中冷热源、分户换热系统,节省了管网投资,降低了输送能耗。用户侧定压补水采用竖向分区减压补水,控制用户侧毛细管系统工作压力,提高了毛细管辐射末端可靠性及使用寿命。置换新风系统采用局部微降板埋地处理,以节省户内空间。其竖向分区的新风系统减小了户内风井面积,增加了使用面积,由双冷源深度热回收新风机组集中回收排风能量,优化了冷凝器配置,热泵回收低温排风能量,提高了内置热泵效率。该项目系统设计对住宅毛细管辐射系统设计具有一定的参考价值。

Abstract: Taking a residential community in Nanjing as an example, this paper presents the hybrid ground-source heat pump system, air conditioning water system, outdoor air system, air conditioning terminal, temperature and humidity control and anti condensation control of the capillary radiation air conditioning system. The air conditioning system adopts the central cold and heat sources and household heat exchange system, which saves the investment of pipelines and reduces the energy consumption for transportation. The user side's constant pressure make-up water adopts vertical partition decompression make-up water to control the working pressure from the user side's capillary system, improving the reliability and service life of capillary radiation terminals. The displacement outdoor air system adopts local micro-drop plate buried treatment to save indoor space. The vertical partition of the outdoor air system reduces the area of the indoor air shaft and increases the use area. The exhaust energy is centrally recovered by the dual cold source deep heat recovery outdoor air unit. The condenser configuration is optimized and the low temperature exhaust energy is recovered from the heat pump to improve the efficiency of the built-in heat pump. This project system has some reference value for residential capillary radiation systems.
