No-Contact Method of Determining Average Working-Surface Temperature of Plate-Type Radiation-Absorbing Thermal Exchange Panels of Flat Solar Collectors for Heating Heat-Transfer Fluid

摘要

A brand new no-contact method of determining the average working-surface temperature of plate-type radiation-absorbing thermal exchange panels (RATEPs) of flat solar collectors (FSCs) for heating a heat-transfer fluid (HTF) is suggested on the basis of the results of thermal tests in full-scale quasistationary conditions.
