PV and Heat Pump System with a Seasonal Storage for Nearly Zero Energy Building
Original language description
The energy system consisting of a combined ground-air source heat pump, PV system and seasonal ground storage unit for an energy passive family house has been developed and analysed by computer simulation. The heat pump, during summer operation, transforms the ambient heat to charge the seasonal ground storage with the use of PV electricity only. Winter operation relies on the heat stored under the house and results in low grid electricity consumption. The simulation analysis has shown the significant decrease in the use of the grid electricity needed for the house (the system’s SPF increased from 3.1 for the reference borehole system to about 6.0) and an increase in usability of the local PV electricity production for energy supply (space heating, hot water) in the house. In total, more than 80 % of the energy supply for the house is renewable energy and the specific non-renewable primary energy needs of the house is under 17 kWh.m-2.a-1 (for space heating, hot water and auxiliary energy).
