DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention V. The present invention relates to a ventilation and heating system in a house which may be called an E system.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. A. Install a heating unit and a ventilation unit on the ceiling or a dedicated installation space. B. Hot air is generated by the heat coil unit of the heating unit, sent out by the built-in fan, and supplied to each room through the hot air outlet duct on the ceiling. Return air from each room is returned to the heating unit through a door undercut. C. Fresh fresh air from the ventilation unit enters the heating unit, mixes it with the room circulating air, and supplies it to each living room. D. A part of the return air from each living room is taken in by the ventilation unit, exchanges heat with the fresh outside air described in C above, and is discharged outside. E. FIG. The outlet for warm air in each room will be provided on the ceiling or above the wall.

[0003]

The above-mentioned prior art has the following problems. A. Heating units, ventilation units, and duct space are required on the ceiling, so the ceiling is low and construction costs are high. B. Since the outlet of hot air in each room is above the ceiling or wall, the vertical temperature distribution in the room is poor. Particularly, since the floor surface temperature is low, the feeling of comfort is impaired. C. High air humidity and low temperature in areas where air does not circulate, such as ceilings and floors, are expected to cause condensation. D. As a countermeasure against the condition described in C above, a dedicated ventilation facility is required. The present invention has been made in view of such problems of the conventional technology, and has as its object to provide the following. A. A heating unit and a ventilation unit will be installed using the underfloor space. B. Hot air is generated by the heat coil section of the heating unit, sent out by a built-in fan, and supplied to each living room through a hot air blow duct under the floor. The return air from each living room returns to the heating unit from the wall and the ceiling suction port arranged in each living room, through the inside of the wall, and the space under the floor. In addition, a part of the return air from each room is collected in the corridor, utility (not shown), etc. through the undercut of the door of each room, and through the wall and ceiling suction port located there, through the inside of the wall, under the floor space. Return to the heating unit. C. The outlet for warm air in each room will be provided below the floor or wall. D. The operation content of the ventilation unit is the same as that of the “prior art”.
