Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an air conditioner, and particularly to a heat radiating device with added radiant heating.

[Conventional technology]

Conventional air conditioners are often installed high up on side walls, taking into account the use of excess indoor space. However, even when heating is performed using an airflow blown diagonally downward, warm air hits the body from above, and the heating cannot be considered comfortable. Therefore, as described in Japanese Patent Publication No. 63-18098, a blower is installed below the outlet of the air conditioner, and the air blown from the main unit is sucked in by the blower and simultaneously blown into the lower part of the room, heating the room from below. Ta.

Furthermore, as described in Japanese Patent Application Laid-Open No. 68887/1987, radiant heating was performed by heating a planar heating element.

[Problem to be solved by the invention]

In order to improve the comfort of heating, the above-mentioned conventional technology uses special separate equipment to improve the temperature distribution in the room or perform radiant heating. Therefore, problems such as the limited space for installing the equipment and low efficiency due to the use of a heat source such as a heater for radiant heating were met.

An object of the present invention is to provide an air conditioner that has a radiant heating function and improves comfort without using separate equipment.

[Means to solve the problem]

In order to achieve the above objective, the wall on which the air conditioner body is installed is made of a ceramic material that emits far infrared rays, such as zirconia, and the air blown from the body is blown onto this wall to heat it. I did it like that. As another means, a row of refrigerant pipes coated with ceramic that emits far-infrared rays is arranged on the front panel of the air conditioner body, and the refrigerant pipes flowing inside the refrigerant pipe are heated.

According to the method described above, the wavelength from the heated part is 7μ to 14μ.
Comfort can be improved by performing radiant heating that can emit far-infrared rays of μ and is effective in improving the human body's sense of warmth.

[Effect]

During heating, high-temperature air from the air conditioner body is blown onto the wall material, which uses ceramic or other material that emits far-infrared rays, to heat it. The far infrared rays emitted from the heated part are absorbed by the human body, creating a type of radiant heating.

On the other hand, a row of pipes placed on the front of the air conditioner body and coated with a substance similar to the ceramic described above, during heating,
Radiant heating similar to the above row is performed by flowing high temperature compressed refrigerant and emitting far infrared rays from the pipe surface.

sent to. Here, the air exchanges heat with the sucked air A, and the high temperature air is blown out from the blow-off grille 15 by the blower fan 6. The blowout grill is a wind direction plate 1
0, it has a structure that can be rotated in the vertical direction, and the air outlet 11 opens so as to blow air toward the side wall 7 during heating. Therefore, the blown-out high-temperature air B comes into contact with the far-infrared radiating wall material 9 made of, for example, zirconia ceramic, which is pasted on the side wall 7 via the heat insulating material 8. The air flows toward the floor C, mixes with the air in the lower part of the room, raises the air temperature, and performs convection heating. Far-infrared rays are emitted from the heated wall material 9 and are directly absorbed by the human body to perform a type of radiant heating.

As explained above, according to this embodiment, the wall material 9 is heated by the high temperature air blown from the air conditioner main body 1,
Since it is possible to perform radiant heating by emitting far-infrared rays from here, there is no need to use separate equipment such as a radiant panel that uses a heater, and it is also effective in emitting far-infrared rays from a wide area. Furthermore, since the high-temperature air flows along the floor after heating the wall material 9, there is an effect that convection heating can be performed from beneath the feet.

As mentioned above, during heating, brightly illuminating the heated wall surface that emits far-infrared rays gives the impression that invisible far-infrared rays are being emitted, which has the effect of promoting the feeling of heating. Moreover, if this light is reddish, the above-mentioned effect will be enhanced.

Next, using FIG. 3, another example of the wall material in the first example will be shown. FIG. 3 shows an example of the far-infrared radiation wall material 9 in FIG. 1. 21 is a mesh made of a metal with good thermal conductivity, and 22 is a reflector made of a material with high far-infrared reflectivity.

Similar to the previous example, when installed on the top of the
High-temperature, high-pressure refrigerant gas sent from an outdoor unit (not shown) is sent to the far-infrared radiation pipe 12, and the refrigerant gas radiates heat and condenses to heat the pipe 12. therefore,
Far infrared rays E are emitted from the pipe 12. The radiation emitted to the back side of the pipe 12 is reflected forward by the reflecting plate 13. The refrigerant that has heated the pipe 12 is sent to the heat exchanger 3, exchanges heat with the blown air A, and heats it.

This air is blown out into the room from the outlet 11 by the blower fan 6.

As explained above, also in this embodiment, radiant heating can be performed by far infrared rays radiated from the pipe 12 installed on the front panel 2.

In addition, the pipe 12 is heated and the heat whose temperature level has been lowered is exchanged with indoor air, and convection heating can be performed at the same time.

In this way, using the heat pump cycle, pipe 1
Heating the pipe 12 has the effect of heating the part corresponding to the pipe 12 more efficiently than when heating the part corresponding to the pipe 12 with an electric heater.
