Hereinafter, a power saving panel and an air conditioner according to an embodiment for carrying out the present invention will be described.

The power saving panel 100 according to the embodiment includes a panel sheet 10, a plurality of openings 20, and a connecting portion 30 as shown in FIGS. 1 to 5, and as shown in FIGS. 8 and 9. The air conditioner 200 is attached to the air intake ports 211 and 221 provided in the indoor unit 210 or the outdoor unit 220 of the air conditioner 200. When the power saving panel 100 is attached to the indoor unit 210 or the outdoor unit 220 of the air conditioner 200, the power consumption of the air conditioner 200 can be suppressed, for example.

The panel sheet 10 shown in FIGS. 1 to 5 includes a resin sheet having a first surface 11 and a second surface 12 which is a back surface of the first surface 11, and fine ceramic particles contained in the resin sheet. Composed. The resin sheet contains a synthetic resin such as silicon rubber. The fine ceramic particles include a component that emits far infrared rays and generates negative ions. The fine ceramic particles have a particle size of preferably 1 μm or more and 100 μm or less, more preferably 5 μm or more and 50 μm or less. For example, the fine ceramic particles may be particles obtained by crushing stepping stones. Dantoishi is a kind of quartz schist produced in the Ryoke metamorphic belt in Higashimikawa, Aichi prefecture. Table 1 shows the components of Dantoishi. Since the fine ceramic particles are particles obtained by crushing step stones, far infrared rays are efficiently emitted and negative ions are generated. The fine ceramic particles are not limited to the above materials, and similar fine ceramic particles in the ground can be used.

The opening 20 is composed of a circular hole penetrating from the first surface 11 to the second surface 12, and has 16 protrusions 21 protruding inward in the radial direction. The protrusions 21 are arranged at equal intervals, have a triangular shape when viewed in the thickness direction, and are inclined at the same inclination angle θ with respect to the first surface 11 when viewed from the center of the opening 20. It has an inclined surface 22. The protrusion length D2 of the protrusion 21 is preferably 5/100 or more and 20/100 or less of the inner diameter D1 of the opening 20, and more preferably 10/100 or more 100 of the inner diameter D1 of the opening 20. 15 minutes or less. The inclination angle θ formed by the inclined surface 22 shown in FIG. 6 and the first surface 11 of the panel sheet 10 is preferably 15° or more and 60° or less, and more preferably 20° or more and 45° or less. On the second surface 12 of the power saving panel 100, as shown in FIG. 7, the peripheral portion 23 of the opening 20 is raised. This makes it possible to increase the inclination angle θ of the inclined surface 22 while reducing the material used for the panel sheet 10. When the opening 20 has the plurality of protrusions 21 having the inclined surface 22, the second surface 12 is attached to the air intake ports 211, 221 of the indoor unit 210 or the outdoor unit 220 so that the second surface 12 faces each other. Air flowing from the direction perpendicular to the surface 11 passes through the opening 20, and the inclined surface 22 changes the direction of the air flow in an oblique direction. As a result, as shown in FIG. 10, a spiral air flow is generated in the air that has passed through the outer peripheral portion of the opening 20. In the figure, 10a is a portion where the rising wall of the panel sheet 10 is cut (cut portion) and creates an air flow.

As shown in FIGS. 1 and 2, the connecting portion 30 is formed, for example, in an uneven shape on the outer periphery 100a of the power saving panel 100. As an example, as shown in FIG. 11, a plurality of power saving panels 100 are connected. It is a thing. Thereby, depending on the size and shape of the air intakes 211 and 221 provided in the indoor unit 210 or the outdoor unit 220 of the air conditioner 200, other requirements, and the like, for example, the required number of sheets is, for example, vertical and/or vertical. , Lateral, diagonal, etc.

Next, the air conditioner 200 to which the power saving panel 100 is attached will be described.

As shown in FIG. 8(A), the power-saving panel 100 includes a floor-standing type indoor unit 210 of the air conditioner 200, a wall-mounting type indoor unit 210 as shown in FIG. 8(B), or FIG. As shown in C), it is attached to the ceiling-mounted indoor unit 210. When mounting on the floor-standing type indoor unit 210, the second surface 12 of the power-saving panel 100 may be opposed to the air intake port 211, and a fixing tool such as tie wrap (registered trademark) may be used for mounting. When it is mounted on the wall-mounting type indoor unit 210, the second surface 12 of the power-saving panel 100 may be faced to the air intake port 211, and the air intake port 211 may be placed and installed. When it is attached to the ceiling-mounted indoor unit 210, the first surface 11 of the power-saving panel 100 may be faced downstream and placed on the net of the air intake port 211.

When the power-saving panel 100 is attached to the indoor unit 210 as described above, as shown in FIG. 12, the air that has passed through the opening 20 of the power-saving panel 100 passes through the filter 212 and further the evaporator coil (heat exchanger). Pass 213. A space of 3 to 5 cm may be provided between the power saving panel 100 and the filter 212. The air that has passed through the opening 20 has a spiral air flow in the outer peripheral portion, and thus strongly contacts the fins of the evaporator coil 213. As a result, the air that has passed through the opening 20 can efficiently exchange heat with the evaporator coil 213, as compared with the air that flows linearly without the spiral air flow. Thereby, the power consumption of the air conditioner 200 can be suppressed.

In addition, as shown in FIGS. 9A and 9B, the power-saving panel 100 has the second surface 12 of the power-saving panel 100 facing the air intake port 221 of the outdoor unit 220 of the air conditioner 200. , Tie wrap (registered trademark) or the like.

When the power saving panel 100 is attached to the outdoor unit 220, the air that has passed through the opening 20 of the power saving panel 100 passes through the condenser unit (heat exchanger) 222 by the fan 223, as shown in FIG. 13. A space of 3 to 5 cm may be provided between the power saving panel 100 and the capacitor unit 222. The air that has passed through the opening 20 has a spiral air flow in the outer peripheral portion, and thus strongly contacts the fins of the capacitor unit 222. As a result, the air that has passed through the opening 20 can be efficiently heat-exchanged by the condenser unit 222, as compared with the air that flows linearly without the spiral air flow. Thereby, the power consumption of the air conditioner 200 can be suppressed.

In the air conditioner 200, the power saving panel 100 may be attached to the indoor unit 210 or the outdoor unit 220. In this case, the amount of power saving panel 100 used can be reduced while suppressing the power consumption of air conditioner 200. Further, when the power saving panel 100 is attached to the indoor unit 210 and the outdoor unit 220, the power consumption of the air conditioner 200 can be further suppressed as compared with the case where the power saving panel 100 is attached to the indoor unit 210 or the outdoor unit 220.

As described above, according to the power saving panel 100 of the present embodiment, a spiral air flow is generated in the air that has passed through the outer peripheral portion of the opening 20, so that this air flow is generated by the evaporator coil 213 or the condenser unit. The heat exchange is efficiently performed by passing through 222. Thereby, the power consumption of the air conditioner 200 can be suppressed. Further, when the power saving panel 100 contains fine ceramic particles and the fine ceramic particles are particles obtained by crushing stepping stones, far infrared rays can be efficiently emitted and negative ions can be generated. When the power saving panel 100 is attached to the indoor unit 210, air containing negative ions can be circulated in the room.
