Problems solved by technology

[0008] However, if the rhombic size of the heat exchanger is increased, the height of the heat exchange ventilator will increase, and it may be difficult to install in an environment where the ceiling height is not enough, and there is a problem that the workability is reduced.
[0009] In addition, if the height dimension of the heat exchange ventilator is suppressed and the dimension in the longitudinal direction (stacking direction) is increased, the area occupied by the product increases, and there is a problem that the workability decreases.

Abstract

PROBLEM TO BE SOLVED: To provide a heat exchange ventilation device capable of keeping heat exchanging efficiency by securing air-supply volume while suppressing a height dimension.SOLUTION: A heat exchanger 14 has a rectangular shape in which sides in parallel with an upper face and a lower face of a casing 1 are longer than sides vertical to the upper face and the lower face of the casing 1 in a front view from an indoor-side side face 1a or an outdoor-side side face 1d, one of a heat exchanger internal air supply passage 6e and a heat exchanger internal exhaust passage 7e is formed along the longitudinal direction of the heat exchanger 14, and the other is formed along the lateral direction of the heat exchanger 14.

Description

technical field [0001] The present invention relates to a heat exchange ventilation device capable of exchanging air through supply air and exhaust air while performing heat exchange between a supply air flow and an exhaust air flow through a built-in heat exchanger. Background technique [0002] A heat exchange ventilator is a device that incorporates a heat exchanger that performs heat exchange between air and air, and performs ventilation by simultaneously supplying and exhausting air while exchanging heat. [0003] For example, Patent Document 1 discloses a heat exchange ventilator that is embedded in a ceiling and arranges a supply air blower and an exhaust blower on the same side of a heat exchanger. [0004] Since this embedded heat exchange and ventilation device is completely embedded in the ceiling, it is difficult to ensure space for maintaining the heat exchange and ventilation device on the upper and lower surfaces of the product. Therefore, it is configured so...
