Simulation Study on Heating Stability of PV/T-GSHP Automatic Control Heating System Based on TRNSYS

The PV/T-GSHP heating control system is proposed to address the energy consumption problem of building in northern China. By using TRNSYS establish an automatic model, heat pump start/stop, water supply temperature on load side tank, and high return can achieve purpose being saving, providing stable heating, heating. results show that has annual fluctuation range 0.01~0.17 kW period for a typical load, efficiency are increased by 14.5% 33.91%, respectively, compared with GSHP system, value cost reduced 8.49% 19.09% traditional coal-fired boiler which shows more economical. It be seen better stability, efficiency, economy, it provides theoretical significance current clean scheme Chinese areas.
