The simulation research of solar assisted heat pump system with the neutral network

Abstract

This paper mainly explores the simulation studies for SAHP system and takes the heating system as research object, sets up the heat pipe evacuated tubular collectors model with the neutral network. Based on the RBF neural network, the predictor-corrector model of collector model is built, as well as a steady-state model of heat pump, heat storage tank model and indoor thermal load model are set up. The validation of simulation model is verified in a Qingdao's building which is equipped with SAHP system, and the simulation is applied with the heating condition for winter. The results show that the system simulation model and program is feasible. Through calculation by the simulation model, the performance of SAHP system is analyzed and the saving heat by the solar collectors is obtained in the whole heating season.
