Thermal Performance of Solar Air Heater Having Absorber Plate with V-Down Discrete Rib Roughness for Space-Heating Applications

Abstract EN

The paper presents results of thermal performance analysis of a solar air heater with v-down discrete rib roughness on the air flow side of the absorber plate, which supplies heated air for space heating applications.

The air heater operates in a closed loop mode with inlet air at a fixed temperature of 295 K from the conditional space.

The ambient temperature varied from 278 K to 288 K corresponding to the winter season of Western Rajasthan, India.

The results of the analysis are presented in the form of performance plots, which can be utilized by a designer for calculating desired air flow rate at different ambient temperature and solar insolation values.
