Remote Multi-way Auxiliary Heating Monitoring System for Solar Central Heating

在对太阳能供热水系统特点及空气源热泵工作原理进行研究的基础上,设计了以空气源热泵和电加热器为辅助热源的太阳能集中供热水远程监测系统,不仅解决了太阳能供热水系统单一热源的局限性问题,同时也实现了远程实时监测.以天津某高校培训中心采用的太阳能供热系统为例,结合当地气候,计算了工程需要的集热器面积和空气源热泵机组数量,详细介绍了采用模块化设计方法开发远程监测系统的过程,并与原天然气供热水系统的水、电和天然气实测消耗量进行了对比.结果表明,多方式辅助加热太阳能集中供热水系统的综合运行费用明显降低,具有较高的应用价值.

Based on the research of the characteristics of solar water heating systems and the working principle of air-source heating pump,a remote monitoring system for solar heating was designed,using air source heating pump and electric heater as the auxiliary heat source.It can not only solve the problem of the limitation of the solar heating system due to single heat-ing source,but also realize the remote and real-time monitoring of the solar water heating system.Taking the solar energy project of a university training center in Tianjin as an example,the required collector area and air source heating pump units were calculated against the local climate.The process of developing a remote monitoring system with modular designs was described in detail,and the actual consumption of water,electricity and natural gas were measured and compared with the natural gas heating system.The results show that the total operation cost of the multi-way auxiliary heating system is obvi-ously reduced,and the system is of higher value in application.
