PURPOSE:To prevent a reduction in an efficiency of thermal recovery during a cooling operation by a method wherein a motor for use in driving a fan disposed at an inner side placed inwardly of a heat exchanger is disposed out of a passage. CONSTITUTION:When a heat exchanging device A is applied for cooling an interior part 6, cold discharged air H passed through a duct D3 and fed from the interior 6 into a discharging passage 12 and a hot supplying air K passed through a duct D1 and fed from an outdoor side 5 into an air supplying passage 11 are heat exchanged from each other by a heat exchanger 2. The heat exchanged cold supplied air K passes through a duct D2 and is supplied to the interior part 6. The hot discharged air H passes through a duct D4 and is discharged to the outdoor part 5. At this time, a motor 31 for driving a fan 3 disposed at an indoor side from the heat exchanger 2 is disposed out of the air supplying passage 11 while being spaced apart by an end plate 32d, so that the supplied air K heat exchanged and cooled by the heat exchanger 2 is not reheated by the motor 31. Accordingly, in particular, an efficiency of heat recovery is not reduced during a cooling operation. |
