Optimization of gas-fired combined cooling heating and power coupled with ground-source heat pump system

This is an improved and developed system of the traditional combined cooling, heating and power system (CCHP) coupled with ground-source heat pump. Based on the conventional air conditioning system, using a comprehensive evaluation indicator consisted of life cycle cost saving rate and primary energy saving ratio, optimizes the system based on the genetic algorithm. Aiming at the limitations of genetic algorithm in practical application, adopts a variety of genetic algorithm to analyse the device capacity and start-stop threshold. Finds that multi-group genetic algorithm is more reasonable than standard genetic algorithm in solving multi-variable optimization configuration. Analyses the variation law of each index with the optimal variables.
