摘要: Abstract The effect of thermal conductivity the absorber plate a solar collector on performance thermo-siphon water heater is found by using alternative simulation system. system assumed to be supplied hot at 50 °C and 80 °C whereas both are used in domestic industrial purposes, respectively. According Rand distribution profile 50, 125 250 l consumed daily. condition shows that annual fraction planning functions collector's configuration factors strongly dependent for its lower values. less dependence observed beyond 50 W/m °C improper above 100 W/m °C factors. In addition, number air ducts total mass flow rate taken show higher efficiency obtained under suitable designing operating parameters. Different heat transfer mechanisms, adding natural convection, vapor boiling, cell nucleus boiling film wise condensation with various radiations. From this study, it siphon achieves characteristic 18% than conventional reducing loss heater.
