【Abstract】 The efficiency of a flat-platf solar collector is investigated in terms of its exergy delivery. The exergy output will be a maximum under optimum entrance conditions. The optimum entrance temperature for the whole day is defined, at which the exergy efficiency of the whole day is maximum through continuously regulating the entrance mass flow rates.更多还原
