【Abstract】 This paper presents an approximate calculation method on the transmissivities and heat loss coefficients of polycarbonate panel and window glass,and compares them with the experimental data.The results show that the transmitivity of west east channel panel is larger than that of north south channel panel,and their heat loss coefficients are approximately equal and nearly one half of that of window glass.更多还原
