Experimental Study on Parabolic Trough Solar Heating System

Abstract:

Firstly, this paper introduces a solar heating system-the parabolic trough solar heating system .which uses the parabolic trough solar collector as the heat source. Secondly, experiments were given about the heating system, including the water temperature in the tank, the ambient temperature and the indoor temperature. Finally, we concluded the instantaneous efficiency and the loss coefficient of the system-the instantaneous efficiency of the system can reach 45% and the loss coefficient is ranged from 1.5 W/(m2•°C) to1.65W/(m2•°C).And in the condition of without auxiliary heat source and the ambient temperature is-5°C~3°C, the indoor temperature can reach 16 °C ~ 20 °C.
