Abstract

PURPOSE:To facilitate the installation and removal of a heat exchanger and readily identify the direction of feed air and vent air by disposing the inlet and the outlet respectively in the opposing side walls of a casing which is normal to the installation/removal direction of the heat exchanger, and aligning the outdoor side inlet and the indoor side outlet, and the indoor side inlet and the outdoor side outlet nearly on a straight line respectively. CONSTITUTION:When a heat exchanger 12 needs to be cleaned as it becomes dirty by performing air conditioning ventilation or normal ventilation, the heat exchanger 12 can be removed after taking off a cover 14 from the casing 1 for cleaning by a cleaner, etc. Since the installation and removal of the heat exchanger 12 is done in the direction normal to the direction of inlets 4, 5 and outlets 6, 7, the feed and vent piping does not come in the way. Because the outdoor side inlet 5 and the indoor side outlet 6, and the indoor side inlet 4 and the outdoor side outlet 7 are respectively aligned on a straight line when viewed from the top of the casing 1, the piping becomes natural and the risk of incorrect piping becomes less.

This is a connecting member for the air supply and exhaust ducts provided in the.

The conventional ventilation system with a heat exchanger is configured as described above, and by operating the exhaust blower 001 and the supply air blower (11), indoor air is drawn from the indoor suction port (4) as shown by arrow A. It is sucked into the box (1), passes through the heat exchanger (12) in the exhaust passage (8) from the arrow port as shown by arrow C, and is blown out from the outdoor air outlet (7) as shown by arrow 2 to the outside. is discharged. On the other hand, outdoor air is sucked into the box body (11) from the outdoor side suction port (5) as shown by the arrow, and is drawn into the air supply passage (11).
The air passes through the heat exchanger (!2) in 9) as shown by the arrow, and is blown out from the indoor air outlet (6) as shown by the arrow T, and is supplied into the room. At this time, heat exchange is performed between the exhaust air flow and the supply air flow in the heat exchanger (12), and exhaust heat is recovered to reduce the heating and cooling load. The heat exchanger (12) gets dirty due to this operation, but to clean it, remove the cover (14) provided on the box body (1), pull out the heat exchanger (12), and use a vacuum cleaner, etc. This is done by

[Problem that the invention seeks to solve]

In the conventional ventilation system with a heat exchanger as described above, the opening for inserting and removing the heat exchanger (12) is located in the same side wall as the side wall of the box body (1) in which the inlet and outlet are formed. Moreover, since it is provided between the suction port and the air outlet, when the heat exchanger (12) is inserted or removed, a supply/exhaust duct (not shown) is connected to the connection member (15) of the suction port and the air outlet. In addition, the indoor side air outlet (6) and the outdoor side air outlet (7) are connected to the box body (1 ) When viewed from above, the ducts intersect and are inserted in the wrong direction, making it easy to make mistakes in duct piping work.

This invention was made in order to solve such problems, and its purpose is to provide a ventilation system with a heat exchanger that allows easy insertion and removal of the heat exchanger and prevents mistakes in the piping of the supply and exhaust ducts. That is.

[Means for solving problems]

The ventilation device with a heat exchanger according to the present invention has an inlet and an outlet provided on opposite side walls of a box perpendicular to the insertion/removal direction of the heat exchanger, an outdoor inlet, an indoor outlet, and an indoor outlet. The inner suction inlet and the outdoor outlet are arranged approximately in a straight line.

[Effect]

In this invention, since the suction port and the air outlet are respectively provided on the opposite side walls of the box which are orthogonal to the insertion/removal direction of the heat exchanger, the duct connected to the suction port and the air outlet is connected to the heat exchanger. There is no interference when inserting or removing the air, and the outdoor air inlet and indoor air outlet, as well as the indoor air intake and outdoor air outlet, are arranged almost in a straight line, making it easy to see the air supply and exhaust directions. Prevent piping mistakes.
