摘要
本课题研究并设计了一种以太阳能为主要能源的户用光伏冷热电联供系统。主要是:1)在能源侧,研究并应用MPPT(Maximum Power Point Tracking)实现光伏发电的最大功率跟踪,提高太阳能利用率;2)基于太阳能的间歇性和不可控性,按照一定充放电规则,设计充电控制器,实现了实时对蓄电池的高效率充电;3)采用半导体制冷器模拟实现冷热联供;4)在负载侧,对系统进行实时智能检测,主要是光伏板下储水箱的水温和水位,冷热水供应箱水温、水位,实现系统余热回收,从而控制水循环系统,实现能源梯级利用;5)搭建实验模型,进行实验,得到了较好的结果。
The research studied and designed a system of household photovohaie CCHP using the solar energy as the main resource. It includes: 1) In the energy side, we studied and applied MPPT (Maximum Power Point Tracking) maximum power tracking photovohaic to improve the utilization of solar energy; 2)the intermittent solar-based and non-controllable, in accordance with certain rules of charging and discharging, we designed a charge controller, real-time high-efficiency battery charging; 3)simulation using semiconductor refrigeration for cooling and heating; 4)on the load side of the system for real-time intelligent detection, mainly in detecting the temperature and level of the water in the water tank under the photovohaic panels. Hot and cold water supply tank water temperature, water level, realization of waste heat recovery system to control the water system, to achieve energy cascade utilization; 5) set up an experimental model, experiment and achieve a good result.
