Active regulation for improving the off-design conditions of distributed combined cooling, heat and power system
This paper briefly introduces the characteristics of Distributed Combined Cooling, Heating and Power (CCHP) System, and indicates that the off-design conditions are the root cause of the performance reduction of system. An active regulation method based on system performance improvement is proposed...
