Effects of solar irradiance on the heating process

Simulates the dynamic thermal process of the low temperature floor radiant heating system and the convector heating system under different solar irradiances. Comparing the indoor temperature and the heating energy consumption of the two systems, the results show that the over heating with the low temperature floor radiant heating system is more notable, and the heating energy ratio of the radiant system to the convective system is increasing with the solar irradiance. Concludes that the convector heating system is more desirable than the low temperature floor radiant heating system in the areas with higher solar irradiance.
