Abstract: In order to optimize the CCHP(Combined Cooling Heating and Power) supply system reasonably, a system of efficient installations of saving is established. It improves system efficiency, and realizes the cascade utilization of energy. On the basis of existing research, a waste heat recovery system is built. It contains a generator set and refrigeration unit. According to the partial load characteristic of the system on the unit in the system modeling alone, the original particle swarm optimization algorithm is optimized, and an example is introduced to verify it. The results show that the system has a good effect on the optimization of the algorithm, and the improved algorithm ensures the stability and practicability of the system operation.
