摘要

The thermal performance of a simple design solar air heater is presented. The conventional flat plate absorber is replaced by a set of tubes filled with a thermal energy storage material. The proposed integrated system heat transfer area and heat transfer coefficient are increased, and the heat loss is reduced. Based on a simple transient analysis, explicit expressions for the heater absorber and glass cover temperatures, effective heat gained, outlet air temperature, and the heater efficiency have been developed as a function of time. The integrated system performance curves are presented, and a marked improvement on the system performance is noticed over the conventional flat plate heater system.
