THE SEPARATED HEAT PIPE SOLAR HEATING SYSTEM

摘要

It is established a separated heat pipe solar indoor heating system .The system is divided into three parts: solar collector, separated heat pipe and indoor heating terminal. The system uses separated heat pipe as heat transfer component. It transfers solar energy from solar collector into the indoor heating terminals. So by the separated heat pipe the system will heat the indoor air with solar energy. The related experiments were carried out. The results showed that the solar thermal utilization efficiency can reach 56% when the solar radiation is at 725W/ m', the evaporation and condensation temperature of heat pipe kept constant at 44.8 °C and 40.2 °C respectively. When the system started to run, it took three or more hours to make the indoor air temperature reach 22 °C -24 °C at sunny or cloudy days. By the experimental data, it is proved that the system is a promising and feasible heating mode in the spacing heating.
