摘要
介绍了水源热泵作为一种节能环保技术在温室大棚温度调节中的应用,并根据机理法建立的温室模型,设计了控制系统,通过有效的控制策略和措施把温室温度调节到最适宜植物生长。同时,详细阐述了温室预测模型及控制系统的硬件、软件实现方法。经试验温室中调试使用,系统操作简单、经济实用,控制精度达到农业生产要求。
As an energy-saving and environment-friendly technology,the application of water-source heat pump units in greenhouse temperature controlling is introduced.Then the model of greenhouse is established,and the auto-control system is designed,adjusting the temperature of greenhouse being fit to the growth of plant by effective strategy and measurement.The design methods of system hardware and software are fully described.The system has been run in tentative greenhouse,the system can be easily controlled,and can make greenhouse meet the environment requirements for crops.
