SIMULATION STUDY ON A NET-ZERO ENERGY HOUSE WITH SOLAR AIR COLLECTORS

摘要

The simulation study was carried out to examine the possibility of the net zero energy house with the air heat collecting system. For the auxiliary heat source of the DHW heating, the heat pump unit was assumed. Providing 30 m~2 of the glazed solar collector and 31 m~2 of pre-heat collector with the 5.5 kW of the high performance PV modules, the all cases achieve the net zero energy in the primary energy. The simulation results showed that the heat pump operate during daytime can reduce the electricity energy use than that operate during the midnight, because the reduced heat loss of the heat storage tank.
