Theoretical And Experimental Study Of The Solar Heat Pump System And Economic Analysis Of The System

The theoretical part of this article established the model of the solar heat pump system components, including the model of the collector plate condenser model, the model of the evaporator, compressor model and expansion valve model, combined with the various parts of the model to establish the model of the system as a whole; in order to improvethe accuracy of the model of the collector plate, the introduction of a neural network calibration was corrected by the theoretical model of the collector plate and verified, the collector plates simulation accuracy has been improved; To make the simulation more convenient, the preparation of a solar assisted heat pump system using C #simulation software, which is immediate export data, quick to view the simulation results, the simulation process more convenient; simulate the operation of the system as a whole, come to the operating performance of the entire system.In this paper experimental department has established a solar heat pump system test-bed, sub-solar panels, heat pump and solar systems overall operating performance of the experimental research and analysis. The experimental system in the winter conditions of solar radiation, water temperature and solar radiation collector within the temperature difference between the import and export; evaporator water temperature and condenser water temperature for the compressor outlet pressure temperature impact, the impact of the compressor power consumption, heat capacity and the absorption coefficient for heat and system heating; the operating performance of the system as a whole. Solar radiation and system heating capacity and coefficient of performance of the experimental values and simulated values were compared on the basis of experimental results, the results show that the experimental results and simulation results consistent high.The typical northern residential heat users, for example, a comprehensive analysis of the feasibility of solar heat pump system used in radiant floor heating, energy saving and environmental protection, while analysis of the system from the long-running process, the economic benefits for the user. Concluded that the system for the northern winter heating energy saving, while the economy in the long run.
