DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIGS. In FIG. 1, reference numeral 1 denotes a rectangular parallelepiped air conditioner main body in which an indoor air treatment device 2 and an outdoor air treatment device 3 are housed, and a floor panel 4 is provided on the upper surface thereof.

The outdoor air treatment device 2 includes an indoor air heat exchanger 4, a drain pan 5 installed below the indoor air heat exchanger 4, and an indoor fan 6.
And its drive motor 7, air filter 8 and the like.

The outdoor air treatment device 3 includes an outdoor air heat exchanger 9, a drain pan 10 installed below the outdoor air heat exchanger 9, and an outdoor fan 11.
And its drive motor 12, compressor 13 and the like.

The floor panel 4 is provided with an inlet 14 and an outlet 15 for indoor air at a portion corresponding to the upper portion of the indoor air treatment device 2. An air filter 8 is installed below the suction port 14. In addition, at a portion of the main body 1 corresponding to the outdoor air treatment device 3, an outside air intake port 16 and an outlet port.
17 are provided. The inner end of the duct 18 is connected to the duct flange 19 provided at the outlet 17.

As shown in FIG. 2, the main body 1 is installed under the floor of the house 20 so that the floor panel 4 thereof is flush with the floor surface 21 of the house 20. 22 and 23 are underfloor vents, duct 18
The outer end of is connected to the underfloor vent 23.

During the cooling operation, the refrigerant discharged from the compressor 13 enters the outdoor air heat exchanger 9 through a four-way valve (not shown),
Here, the air is condensed and liquefied by exchanging heat with the outside air blown by the outdoor fan 11. The liquid refrigerant enters the indoor air heat exchanger 4 via an expansion valve (not shown), evaporates by exchanging heat with the indoor air blown by the indoor fan 6, and then returns to the compressor 13 via the four-way valve.

During this cooling operation, the room air is sucked into the room air treatment device 2 through the suction port 14, and the dust in the air is removed by passing through the air filter 8. Next, this air is sucked into the indoor fan 6 and is energized, and is cooled by exchanging heat with the refrigerant when passing through the indoor air heat exchanger 4, and then blown out into the room from the air outlet 15.

On the other hand, the outside air enters the underfloor through the underfloor vent 22, passes through the underfloor, and is sucked into the outdoor air treatment device 3 through the suction port 16. Then, after being sucked and energized by the outdoor fan 11, the temperature of the outdoor air heat exchanger 9 is increased by exchanging heat with the refrigerant when passing through the outdoor air heat exchanger 9. Discharged outdoors.

Since the four-way valve is switched during the heating operation, the refrigerant circulates in the opposite direction to that during the cooling operation, and the indoor air heated by flowing through the indoor air heat exchanger 4 functioning as a condenser blows out the air. It is blown into the room from 15.

[0022]

According to the present invention, since the main body of the air conditioner is installed under the floor of a house, it cannot be seen by people except the floor panel. Therefore, the space under the floor can be effectively utilized and the installation space inside and outside the air conditioner can be saved. Since the indoor unit, the outdoor unit, and the refrigerant pipes and electric wires that connect them to each other unlike the conventional ones are not exposed to the inside wall of the room and the outside of the house, their aesthetics can be improved.

Further, during the heating operation of the air conditioner, warm air is blown into the room from the air outlet of the floor panel, so that the room temperature near the floor can be easily raised, and therefore the temperature distribution in the room can be increased. It is possible to give a comfortable air-conditioning feeling to the occupants of the room by using as a cold head heat.
