  • PCM integrated space heating system is a novel off-grid solution.
  • Air is used as the heat transfer medium for keeping the room temperatures in optimum range.
  • The results validated the space heating solution by maintaining room temperature above 15 ℃.
  • For 24 hours, while the ambient varied between 0 and 5 ℃, the room temperature was controlled in the range 15-20℃.
  • The current system needs aesthetical and functional improvements to be commercialized.


Phase change materials (PCM) integrated solar-powered space heating plays a crucial role in maintaining thermal comfort in cold regions where the temperature shoots down to -10 ℃. This paper presents the experimental results of using PCM HS22 integrated with solar energy to maintain comfortable conditions inside the experimental prototype in the cold ambient. The solar energy is stored in PCM during the daytime to use it for night-time during off-sunshine hours. The results show that the room temperature is maintained in the 10 to 20 ℃ temperature range when the ambient was between -10 to 0 ℃. The room temperature was maintained consistently for 24 hours.
