Study on Solar Energy Heating System in the Cold Region

摘要

This article researched on solar radiant floor heating system between theory and experiment cold region. The experiment is basis on home water heater as the main source of solar radiant floor heating system, solar collector area of 1.8m2, water capacity 0.208m3, heating load for 130w/m2. In addition to the electric coil consumed energy for prevent freezing damage of outdoor pipes. The entire system is any other consumption. Test results between techno-economic analysis and calculation show that: a total test system saved energy 2262230.22 kJ, the system payback period is 3.4 years.
