Performance Assessment of Heat Pump and Solar Thermal Heating with Seasonal Storage Systems for Smart Microgrid Research Center Building at IAUN

In this research, the building of the Intelligent Microgrid Research Center in Islamic Azad University, Najafabad Branch (IAUN), has been selected as a sample space. The energy required to heat the building is transferred to the seasonal storage tank in the basement by flat solar collectors with an installation angle of 47.5°. This heat is transferred to the internal space via a geothermal heat pump in the winter. The thermodynamic study of the proposed system is simulated by MATLAB software. The system losses have also been evaluated, and thereby an optimal solar heating system procures all heat demand of the building. The required collector surface is 240 square meters, the tank volume is 2200 cubic meters, and the insulation thickness is 1.2 meters.
