PURPOSE:To be able to make highly efficient ventilation by placing heat source panels separated by a space at the wall of a room and placing a total heat exchanger in the space. CONSTITUTION:In the intermediate seasons such as spring and autumn when space cooling and heating are not necessary, dampers 12, 16 are completely closed and dampers 13, 17 are also completely opened, which allows a room 1 to ventilate without passing through a total heat exchanger 8. At the operation of space cooling and heating in summer and winter, complete opening of he damper 12, 16 and complete closing of the damper 13, 17 cause whole fresh air from a suction hole 9 to pass through the suction flow path 6 of the exchanger and whole exhaust air to pass through the exhaust flow path 7 of the exchanger. Therefore, total heat in the exhaust air is recovered in fresh air by the function of the exchanger. Further, after air released into a space 4 from the outlet 6b of he path 6 absorbs heat leaked into the space 4 from heat source panels 5, the air is blown off into the room 1 through blow-off holes 19. |
