NEW INVESTIGATIONS IN SOLAR AIR HEATING COLLECTORS

The objective is to create and explore the easy-folding, disrupting, easily portable air heating solar collectors, which can be inflated and disassembled as many times as needed. The solar collector has to be constructively simple and cheap as well as simple and easy to transport. That could be an inflatable air heating solar collector. The inflatable base could be a good insulator on the one hand and absorbent on the other hand. We need to find out the air-heating collector efficiency. The study results confirm that the manufactured solar collector is sufficiently effective and easy to produce with small financial contributions. The average ambient air temperature increase in the experiments is 10.2 degrees C and max increase is up to 16 degrees C. This collector gives good correlation with the air heating degree and radiation (r = 0.93) and the efficiency coefficient of this collector is eta = 0.63. Comparing the efficiency of the collector manufactured with another coating and the absorbent material collectors shows that the collector is manufactured for use in air heating.
