【摘要】：地源热泵毛细管空调系统是一种新型的空调系统。本文结合苏州一实际空调工程,对于浅埋式地源热泵与毛细管空调组合的系统进行研究。根据工程实例,对空调系统进行了传热分析和(?)分析。分析表明对于地质坚硬的地区,采用浅埋式双U地埋管可以有较好的传热能力；在品质上毛细管末端房间在达到相同制冷效果的条件下相比风机盘管房间节能25%。因此毛细管辐射空调末端在一定程度上可以弥补地埋管浅埋的不足。根据空调控制原理对空调系统设计了实时监控平台并完成了安装和调试。监控平台实现了对地源热泵、新风机组、空调末端环境监控系统的集成,可以对空调系统的运行和能耗利用进行监测。监控平台安装前,通过温湿度记录仪对空调末端房间进行冬夏季工况测试,结果表明毛细管房间比风机盘管房间稳定且舒适性更高,但存在一定的结露风险。监控平台安装后,对新风送风温度的监控表明新风温度控制基本稳定,受机组空调侧出水温度波动影响较小。对地源热泵冬季的运行特性进行监测,监测时段系统冬季工况下热水供回水最大温差在4℃,有足够的换热能力。12月4日高峰负荷时段平均COP为3.38,基本达到能效要求,但与其他深埋地源热泵包括深埋地源热泵与毛细管空调组合系统相比COP均较低。12月8日测得机组在1到4台压缩机台数下的COP分别为2.99、3.66、4.19和4.52。
[Abstract]:Ground source heat pump capillary air conditioning system is a new type of air conditioning system. In this paper, the combination of shallow buried ground source heat pump and capillary air conditioning system is studied. According to the engineering example, the heat transfer analysis and (?) Analysis The analysis shows that the shallow buried double U buried tube can have good heat transfer ability in the hard geological area, and the capillary end room can save 25% energy compared with the fan coil room under the same cooling effect in quality. Therefore, the end of capillary radiation air conditioning can make up for the deficiency of buried pipe. According to the principle of air conditioning control, the real-time monitoring platform is designed and installed and debugged. The monitoring platform realizes the integration of ground source heat pump, fresh air unit and air conditioning terminal environment monitoring system, which can monitor the operation and energy consumption of air conditioning system. Before the installation of the monitoring platform, the temperature and humidity recorder was used to test the air conditioning terminal room in winter and summer. The results showed that the capillary room was more stable and comfortable than the fan coil room, but there was a certain risk of condensation. After the installation of the monitoring platform, the monitoring of the fresh air supply air temperature shows that the fresh air temperature control is basically stable and is less affected by the fluctuation of the effluent temperature of the air conditioning side of the unit. The operating characteristics of ground-source heat pump in winter are monitored. The maximum temperature difference of hot water supply and backwater is 4 鈩，
