A Survey of Air-heater Options
Solar-heated air can be used in a wide variety of applications, but it is a limited resource. Only so much sunshine strikes each square foot of the earth, and a well-built collector system will typically deliver about half of this energy to a house in the form of heat. The way this heat is used often means the difference between a useful, cost-effective system and one that never seems to perfor...
متن کاملefficient solar air heater with perforated absorber for crop drying
outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...
متن کاملThermal Performance of a Double-pass Solar Air Heater
This study analyzes the thermal performance of solar thermal energy using double-pass absorber plate in Sanandaj, Iran. To this end, a mathematical model was encoded according to the energy and exergy balance equations and solved by MATLAB software. Given the environmental conditions and radiation intensity of a winter day in Sanandaj, the effects of external parameters such as radiation intens...
