Claims

[Scope of claim for utility model registration] Air inlets and outlets such as an outside air intake port 2, an exhaust port 3, an air supply port 4, and a return air port 5 are provided in the upper part of the aircraft body 1,
In addition, in a floor-standing total heat exchanger unit in which a total heat exchanger 6 is disposed in the central part of the fuselage 1, the total heat exchanger 6 is approximately U-shaped from the outside air intake port 2 to the air supply port 4 with the total heat exchanger 6 as an axis. A substantially U-shaped ventilation passage 8 extending from the return air port 5 to the exhaust port 3 is provided in communication with the ventilation passage 7 in the shape of a cross, and an RA fan is provided below the ventilation passages 7 and 8 on both sides of the total heat exchanger 6. 9, RA motor 10
A floor-standing total heat exchanger unit characterized in that various mechanisms such as an EA fan 11 and an EA motor 12 are arranged respectively. In the floor-standing type total heat exchanger having the above configuration, several silencing mechanisms 13...14 are arranged protrudingly in the vicinity of the exhaust ports 3, air supply ports 4, etc. of the ventilation passages 7, 8, and the ventilation passages 7, Z-shaped sound deadening passage 7' inside 8
, 8'. In the floor-standing total heat exchanger having the above structure, air inlets and outlets such as an outside air intake port 2', an exhaust port 3', an air supply port 4', and a return air port 5' are provided on the upper surface of the housing, and several air inlets and outlets are provided inside. A noise reduction chamber 16 formed by projecting noise reduction mechanisms 13, 14, and forming an S-shaped or Z-shaped ventilation passage 15 is integrally connected to the upper part of the fuselage 1. A floor-standing total heat exchanger unit according to claim 1 of the utility model registration claim.
