Research on Solar Heating System with Phase Change Thermal Energy Storage

In order to apply solar energy for heating purpose, we study the performance of solar heating with phase change thermal energy storage. Tests and analysis have been carried out to obtain the useful energy and thermal efficiency of the system, the energy consumption for room heating and the solar fraction, The research results showed that the heating efficiency of the system would be 31.7% and the solar fraction would be 83.6% while the average temperature indoor was 14.9 °C and outdoor was -1.5 °C The temperature change in the heating room was bigger than that in the contrast. Compound heating systems with solar collectors and phase change materials are popular nowadays as they are meeting the design requirements of buildings with energy conservation integration.
