Abstract

PURPOSE:To thin the whole of the titled device and promote the spread of atmosphere supplied into a room by a method wherein split heat exchangers are provided in parallel in the accommodation chamber of the heat exchangers while an outer casing is provided with atmosphere blow-off ports for three directions. CONSTITUTION:Heat exchangers are split into at least two pieces two pieces and are provided in parallel in an outer casing 9, therefore, the sizes in up-and- down direction of respective heat exchangers 2 may be reduced than the size of the same in the case of single heat exchanger and, accordingly, the whole of the titled device may be thinned. Blow-off ports of atmosphere for the inside of a room are opened at the front side as well as both side surfaces of the outer casing 9, therefore, the spread of atmosphere, supplied into the room, may be improved.

る。As described above, in the ventilation system of the present invention, the heat exchanger used is divided into at least two parts and installed in parallel inside the outer box, so that the vertical dimensions of each heat exchanger can be kept in the same size. The size of the heat exchanger can be made smaller than that of the heat exchanger, which makes it possible to make the entire device thinner. These vents are installed at three locations, allowing the outside air to spread throughout the room, and by installing an adjustable damper at each of the multiple outlets, the direction of the outside air blowing into the room can be changed to the desired direction. It also becomes possible. Since the other internal heat exchangers are used in parallel, the static pressure loss of the heat exchanger as a whole is small, which has the effect of enabling low-noise operation.
