基于Niagara Framework与物联网技术,搭建了一种太阳能-空气源热泵空调系统监控管理平台。该平台通过JACE网络控制器、I/O模块和现场各类传感器等硬件架构,实现了太阳能-空气源热泵复合系统、新风系统和空调末端房间三个子系统的网络集成。为使系统节能,设计了风机盘管与热泵机组一体化控制、循环泵变频控制、新风机组控制等节能措施。平台可根据末端风机盘管的启停控制空气源热泵机组的节能启停,根据室内CO 2 浓度自动控制新风机组的启停等。最终用户可通过web浏览器远程访问监控管理平台,实现对空调系统的实时监测和控制。经试验测试,平台运行稳定并具备完善的智能监控与管理的功能,很大程度地降低了系统的能耗,对整个空调行业的智能化监控管理起了推动作用。未来将对平台所采集的系统数据进行处理分析,保证数据的准确性,更好地提高系统的节能运行性能。

A monitoring and management platform for solar energy and air source heat pump air conditioning system based on the Niagara Framework and Internet of things has been built.The platform realizes network integration of three subsystems of solar-air source heat pump composite system,fresh air system and air-conditioning terminal room through hardware architecture including JACE network controller,I/O modules and various field sensors.In order to save energy,energy-saving measures such as integrated control of fan coil and heat pump unit,variable frequency control of circulating pump,and control of new air unit are designed.The platform can control the energy saving start and stop of the air source heat pump unit according to the start and stop of the end fan coil;and automatically control the start and stop of the fresh air fan unit according to the indoor CO 2 concentration.The end user can remotely access the monitoring and management platform through a web browser to realize real-time monitoring and control of the air conditioning system.Through experimental tests,the platform is stable and has perfect intelligent monitoring and management functions,which greatly reduces the energy consumption of the system and promotes the intelligent monitoring and management of the entire air-conditioning industry.In the future,the system data collected by the platform will be processed and analyzed to ensure the accuracy of the data and improve the energy-saving operation performance of the system.
