The design and construction were based on the omega-shaped micro grooves heat pipe air cooling PV/T component by taking advantage of the heat pipe with axial omega-shaped micro grooves wick
which has higher heat recovery efficiency and quality in middle or low temperature waste heat recovery field. Under active cooling and passive cooling conditions
thermal/electrical properties and hot air temperature of the PV/T component were tested and analyzed respectively. The test results indicated that the component's average electric efficiency
average thermal efficiency
average total efficiency
average energy efficiency and hot air temperature are more than 11%
about 30%
about 60%
more than 13%
and more than 41℃. The electric efficiency
thermal efficiency and exergy efficiency of active cooling PV/T component were significantly higher than that of passive cooling PV/T component. Compared with traditional PV/T component
this PV/T component has obvious performance advantages. The collected hot air can be used for building heating
strengthening ventilation as well as hot air drying.
