Based on the application of solar energy, the principle of a distributed energy system for cooling-heating-power cogeneration for a single building was discussed. Solar energy was used as the only heat source to drive a closed Brayton cycle to generate power. The waste heat dissipated by the turbine was utilized by a recovery refrigeration cycle to provide cooling or was directly transferred by heat exchangers for heating. When the system was further combined with a fuel-cell stack, the whole system can provide cooling-heating-power continuously in day and night. The system did not consume fossil fuel and dissipate no pollutant with a high energy efficiency. It's worthy further study and introducing to practical application to solve the power crisis.
