Household Photovoltaic Cchp System

The research studied and designed a system of household photovoltaic 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 photovoltaic 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 photovoltaic 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.
