PURPOSE:To facilitate the connection of the titled device to ducts by providing upper and lower chamber-like flow control parts leading to ducts within the inner part of a base box. CONSTITUTION:A solar heat collecting device 1 forms, in a base box 2 provided with a slant, upper and lower flow control parts 5 and 6 to which ducts T1 and T2 are connected by extending upper and lower resistance plates 3 and 4 crossing the inner part of the base box 2, and at the same time, a heat collecting body 7 is accommodated into a space formed between the upper and lower resistance plates 3 and 4. By circulating air from the duct T2 to the duct T1, hot air due to solar heat by the heat collecting body 7 is discharged from the room to perform air conditioning thereof. Air flowing into the lower flow control part 6 through an air inlet 8 is controlled at a throttling part 10, and flows into respective heat collecting chambers A in a substantially equal quantity. Accordingly, the collection of solar heat and the thermal efficiency are increased. Moreover, the upper and lower flow control parts 5 and 6 are capable of functioning as chambers, supplying of air to the heat collecting chambers A, and taking out hot air therefrom. |
