The impact of flow rate on the thermoelectric performance of photovoltaic/thermal water heater
This study utilized numerical simulations to examine the heat transfer mechanism of photovoltaic/thermal(PV/T)water heaters,aiming to enhance their photovoltaic and photothermal efficiencies.It was found that as the water flow rate increases,there is a corresponding improvement in the system's photovoltaic,photothermal,and overall efficiencies,along with a gradual reduction in the heat loss coefficient.In terms of temperature distribution,increased water movement significantly lowers the temperature of the PV/T module,particularly around the heat collector tube,which results in a more uniform temperature distribution.A temperature distribution function for the PV/T module at different water flow rates was obtained based on the least squares method.
