摘要
泵给水电即热式热水连续生产技术应用前景广泛,出水速度快、水温和水量控制准确、高效节能是技术的核心,但水泵电机和电加热组件等不确定,使得技术推广实现多用途控制成为瓶颈。结合文献和科学原理开展研究,对典型技术应用系统的组成以及即热机理等进行了详细的分析,创新性提出了易于推广的通用策略并应用于技术模型进行实践研究。研究表明,该技术通略可使系统灵活调整选用调功式、调速式等节能方式,实现温量的准确控制。
Hot water successive producation technology by bump supplying water and instant electricity heating has broad application prospects. The technology's cores involve fast speed of water output, accurate control about water temperature and water quantity, high efficiency and energy saving. Because water bump moters and electricity heating modules are uncertain, it will become bottleneck that the technology is popularized to ensure multiple usage control. The research was made by combining literatures with scientific principles. It is analyzed in detail that the modules about typical technology systems and the instant heating principle, etc. The paper puts forward a kind of innovative universal strategy of being easily popularized, and the practical research was made by using it in the technology model. The research shows that the strategy can make the systems choose flexibly energy-saving measures between the power-regulation mode and the speed-regulation mode, and achieve accurate control about water temperature and water quantity.
