Design of Combined Cooling Heating and Power System Based on Solar Photothermal

This paper designs a Combined Cooling Heating and Power (CCHP) system that integrates solar collector system and internal combustion generator. The system can generate electricity through internal combustion engine, and simultaneously use high temperature flue gas, cylinder jacket hot water and solar hot water in internal combustion engine, cooling and heating. The system is operated in the teaching area of Weifang Institute of Technology. It can achieve good comfort by completely utilizing solar energy and power generation heat/heating. No additional energy is needed, and the annual energy contribution rate of solar energy exceeds 50%.
