초록

Experimental study on the operating characteristics of a solar hybrid heat pump system according to indoor setting temperature were carried out during spring and winter season. The system was consisted of a concentric evacuated tube solar collector, heat medium tank, heat storage tank, and heat pump. As a result, the heating load was increased by 21.1% when the indoor setting temperature rose by 2oC for the same ambient temperature. Besides, the spring season had good outdoor conditions compared to the winter season, therefore the heating load was reduced and heat gain by collector increased, relatively. In case of the winter season, the solar fraction was shown less than 10% because the heat losses of system and space increased considerably. The solar fraction decreased significantly as the indoor setting temperature increased.
