Description

[Detailed description of the invention] This invention ensures that cold and hot air is directed in the desired direction in the room at the front of the aircraft without having to adjust the wind direction using a wind direction adjusting blade fitted to the air outlet grill in a wall-mounted floor-mounted air conditioner/heater. This invention relates to an air-conditioning/heating machine whose purpose is to provide a comfortable indoor environment at all times by blowing air to the room, and to ensure and easily perform various tasks such as inspecting and cleaning the interior of the aircraft from the front of the aircraft.

Usually, a floor-standing air conditioner/heater is installed in the machine casing 1 as shown in the first diagram.
A blower 2 is installed in the lower part of the inside of the fan, a blower passage 3 is formed in the upper part of the blower 2, and a heat exchanger coil 4 is installed, respectively.
Directly above the heat exchanger coil 4 and at the top of the machine casing 1, an air outlet grille 5 having several wind direction adjusting blades is provided.

In addition, most of the mechanisms of the heat exchanger coil 4 lengthen the air blowing distance and elapsed time within the heat exchanger coil 4, making the heat exchange efficiency more effective, and making it easier to treat dew condensation. In order to make the shape compact, the heat exchanger coil 4 has a structure in which the heat exchanger coil 4 is tilted backward in the air passage 3. Therefore, although the heat exchange efficiency is good, due to the rising airflow after long-term use, fine dust and foreign matter accumulates between the inclined inner surface of the heat exchanger coil and the 4' surface of its fins, and the air blower becomes noticeably obstructed. This worsens the efficiency and reduces efficiency, but since this is on the back side of the coil, cleaning and inspection from the front of the fuselage is completely impossible, and the airflow after heat exchange flows into the space above the fuselage heat exchanger coil 4. Even if the wind direction is adjusted using the wind direction adjusting blades 6 of the air outlet grille 5, it is difficult to blow cool and warm air smoothly and favorably toward the front of the room.

The present invention attempts to eliminate the above-mentioned drawbacks, and its outline is to provide an air outlet grill 5 at the top of the fuselage 1, a blower 2 below, and an air passage 8 above the blower 2. , a heat exchanger coil 8 formed by fitting and arranging a large number of dogleg-shaped curved flat heat exchange pipes 9 in the air passage 3 with the curved inner surfaces facing the front side is arranged in a manner that the heat exchanger coil 8 is inclined toward the front side. It is an object of the present invention to provide an air-conditioning/heating machine characterized in that the front panel 1' in front of the heat exchanger coil 8 can be freely opened and closed.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG.
This airframe has an air passage 3 formed in the upper part, a vertically elongated heat exchanger coil 8 disposed in the air passage 3 in an inclined manner slightly forward, and an air outlet grill 5 provided on the upper surface.

The pipe constituting the heat exchanger coil 8 is the second pipe.
As shown in the figure, a suitable number of flat pipes 9 which are curved into a dogleg shape are fitted and arranged in the fins with the curved inner surface facing forward, depending on the function of the coil.

In such a structure, the air blown from the air blower 2 rises, and heat is exchanged with the heat exchanger coil 8 to an appropriate temperature. The air flows in an arc shape as shown by the arrow in the figure, and this air is further blown out in an arc shape toward the front of the room through the outlet grille 5, making it easy to obtain the ideal distribution of cool and hot air inside the room.

As described above, the air conditioner according to the present invention has the heat exchanger coil 8 inclined forward in the blower 3, and the flat heat exchange pipe 9 that curves the coil forward in a dogleg shape. Since it is formed by using the curved dogleg-shaped pipe 9, the air from the blower 2 does not blow directly above the curved dogleg-shaped pipe 9 as in the conventional case.
It naturally flows in an arc shape along the curved surface of the coil, and this causes turbulent flow between the adjacent curved doglegged pipes 9, 9, which naturally improves the heat exchange efficiency within the coil. , especially curved doglegged pipe 9
By the synergistic action of the airflow direction adjustment blades 6 of the ventilation grille 5 and the ventilation grille 5, the air can be distributed in a desired direction indoors.

Therefore, it is not necessary to install complicated air blow adjustment inside the machine or on the air outlet grill as in the past, and by simply removing the front panel 1' of the machine body 1, the inclined inner surface of the heat exchanger coil 8 tilted forward can be adjusted. Since it is located at the front of the machine, it also has the advantage that inspection and cleaning of the inclined surface and the interior of the vessel can be carried out much more easily and simply and reliably from the front.
