Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an air conditioner with a radiant panel, which has an improved inlet structure for heat exchange air in an indoor heat exchanger.

(Prior Art) An air conditioner equipped with a radiation panel on the front surface has been proposed in order to improve the heating effect. Specifically, this air conditioner with a radiation panel has a structure in which the radiation panel is attached to the front of the indoor heat exchanger in the casing of the indoor unit, facing the room.

(Problems to be solved by the invention) However, in such an air conditioner with a radiant panel, in terms of heat exchange performance, a place where heat exchange air should be uniformly sucked from the front of the indoor heat exchanger, Since the radiant panel is located in front of the indoor heat exchanger, an air inlet is formed in the upper part of the casing, etc., and heat exchange air is passed through the gap formed between the indoor heat exchanger and the radiant panel. It adopted a structure that allows it to be sucked into. For this reason, there is a problem that the air flow sucked into the indoor heat exchanger is non-uniform, the wind velocity distribution is deteriorated, and the heat exchange performance is deteriorated.
Further, since it is necessary to form a gap between the indoor heat exchanger and the radiation panel, the thickness of the casing has increased.

Therefore, the present invention has been made in consideration of the above circumstances.
It is an object of the present invention to provide an air conditioner with a radiant panel that can improve the heat exchange performance of an indoor heat exchanger and reduce the thickness of a casing.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention relates to an air conditioner with a radiation panel in which a radiation panel is mounted in front of an indoor heat exchanger to face the room. A plurality of air suction holes for sucking the heat exchange air of the indoor heat exchanger are formed in the radiation panel.

(Operation) Since the heat exchange air is sucked through the plurality of air suction holes formed in the radiant panel, it is possible to uniformly suck the heat exchange air from the front surface of the indoor heat exchanger. . Further, since the air suction port is secured in the radiation panel, the gap between the radiation panel and the indoor heat exchanger can be made as small as possible.

Embodiment An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In Fig. 1 showing a side sectional structure of an indoor unit of an air conditioner with a radiation panel, 1 is a casing of the indoor unit, and an indoor heat exchanger 2 is mounted in the casing 1 in an upright state. The front surface of the casing 1, which is the front surface of the heat exchanger 2, faces the room and radiates the radiation panel 3.
Is attached. The radiation panel 3 includes a radiation plate 5 having a heat pipe 4 attached to the back surface thereof, and a heat insulating material 6 attached to the back surface of the radiation plate 5 so as to cover the radiation plate 5.
As shown in FIGS. 1 and 2, the radiation panel 3 is formed with a plurality of air suction holes 7 for sucking the heat exchange air of the indoor heat exchanger 2 over the entire surface and without interfering with the heat pipe 4. ing. In this case, the size and position of the air suction hole 7 are set so that sufficient heat exchange air can be supplied to the indoor heat exchanger 2 without impairing the radiation capability of the radiation panel 3. The hole diameter D ₁ of the radiation plate 5 and the hole diameter D _{2 of the} heat insulating material 6 in the air suction hole 7 may be equal to each other.
In order to avoid contact between the air suction hole inner circumference 8 of the radiation plate 5 and the suction air, the hole diameter D ₁ of the radiation plate 5 is made larger than the hole diameter D ₂ of the heat insulating material 6 as shown in FIG. Inner circumference of suction hole 8
The lining 9 of the heat insulating material may be formed so as to be equal to the hole diameter D _{2 of} the heat insulating material 6, and the back surface of the heat insulating material 6 has an enlarged diameter D ₂ of the air suction hole 7. The holes 10 may be formed so that the suction air flows in a wide range with respect to the indoor heat exchanger 2.

At the upper part of the casing 1 and the lower part of the front surface, there are air outlets 11,
12 are respectively formed, and these air outlets 11 and 12 are formed.
At the upstream side of the above, cross flow fans 13 and 14 for sucking air from the air suction hole 7 and blowing out from the air outlets 11 and 12 are mounted, respectively. The air outlets 11 and 12
May be only one of them. Reference numeral 15 in FIG. 1 denotes a drain receiver provided below the indoor heat exchanger 2.

With this configuration, when the cross flow fans 13 and 14 are driven, air is sucked through the plurality of air suction holes 7 formed in the radiation panel 3 and is directly supplied to the indoor heat exchanger 2 from the front surface thereof. become. Therefore, the indoor heat exchanger 2
Will be given a uniform flow of suction air,
Heat exchange performance is improved. Moreover, since it is not necessary to secure a gap between the indoor heat exchanger 2 and the radiation panel 3, the casing 1 can be made thin.

Further, since the lining 9 of the heat insulating material is formed on the inner circumference 8 of the air suction hole of the radiating plate 3 as in the embodiment, the radiating plate 3 which has a high temperature during the heating operation is not cooled by the suction air, and the radiation performance There is no such thing as a decline.

Although the drain receiver 15 is separately provided in the embodiment,
As shown in the drawing, the indoor heat exchanger 2 is inclined so that its lower end portion is close to the radiation panel 3, and the drain receiver 20 is engaged with the heat insulating material 6 of the radiation panel 3 by the lower end portion of the indoor heat exchanger 2.
May be integrally molded, which reduces the cost and saves space unlike the case where the drain receiver is provided separately.

[Effects of the Invention] In summary, according to the present invention, the following excellent effects are exhibited.

Since a plurality of air suction holes are formed in the radiation panel located in front of the indoor heat exchanger, the suction air can be uniformly given to the indoor heat exchanger, and the heat exchange performance of the indoor heat exchanger can be improved. .

Therefore, unlike the case where air is sucked through the gap between the indoor heat exchanger and the radiation panel, the gap between these indoor heat exchanger and the radiation panel can be made as small as possible, and the casing can be made thin.
