Thermal and Electrical Performance Experimental Study of a Bi-fluid Type Photovoltaic/thermal Roof Module
In this paper,a new type of bi-fluid photovoltaic/thermal roof module without cover is proposed.By combining the water-cooling duct of tube-plate with the air-cooling duct of baffle-plate,the water capacity of the component is reduced and the air outlet temperature is increased,and the supply of hot water and hot air for the module is realized.By building a performance test bench with a stable testing environment,the temperature difference between the inlet and outlet of the module and temperature of the module with solar irradiance and working fluid flow was studied,and the all-day thermal and electrical performance of the module was analyzed.The results show that the module has an obvious cooling effect.The electrical efficiency of water cooling and air cooling modes can reach up to 16.80%and 17.62%.It has high all-day comprehensive performance and the all-day primary-energy saving efficiency is up to 74%.
