D-49 Comfortable and Energy-Saving Thermal Store Floor Heating System combined with Air Source Heat Pump using Solar Radiation : Part8. Study of Heat-Storage Efficiency by Solar Radiation for Heat Pump Control on the Winter

Abstract

In this paper, effects of the heat pump control method to thermal quantity stored into the Phase Change Material (PCM) panels by solar radiation and thermal balances of the laboratory, was investigated. We determined that appropriate water temperature inlet to the PCM panel on the floor. In addition, we confirmed that small quantity of heat storage by Heat Pump at night cause large quantity of heat storage by solar radiation. Also, we experiment on heat-storage efficiency by solar radiation according to heat storage quantity by Heat Pump as the tomorrow weather condition.
