Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a floor-standing fan coil unit (hereinafter referred to as FCU).

[0002]

[Prior art]

 The FCU is an indoor air conditioner in which a fan, a heat exchanger, a filter, and the like are housed in a casing, and various types of air conditioners have been conventionally devised.

For example, the FCU disclosed in Japanese Laid-Open Patent Publication No. 1-137128 aims to obtain a good temperature distribution in the indoor living space by providing air outlets at two positions above and below the airframe. In this FCU, the upper outlet is dedicated to cold air, the lower outlet is dedicated to heating, and the upper outlet is designed to blow cool air upward in the room. There is. Further, in this FCU, since the suction port is provided on the rear surface of the machine body, it is necessary to provide a space between the wall surface and the rear surface of the machine body.

[0004]

[Problems to be solved by the device]

 Therefore, a technical problem to be solved by the present invention is to provide an FCU that can make the temperature distribution in the room more uniform and can effectively use the limited space in the room.

[0005]

[Means, actions and effects for solving the problem]

 The present invention was devised to effectively solve the above problems, and provides a floor-standing FCU having the following configuration.

That is, the floor-standing type FCU of the present invention has a height extending to the vicinity of the ceiling surface, and has an upper air outlet provided on the front surface and both side surfaces near the upper edge of the airframe, and the airframe. The lower air outlet provided below the upper air outlet on the front surface, the air inlet provided on the front of the machine, and the ratio of the air sucked from the air inlet to the upper air outlet and the lower air outlet can be arbitrarily set. And a damper that can be set.

In the floor-standing type FCU having the above structure, the upper outlet exists near the upper edge of the airframe extending to the vicinity of the ceiling surface (that is, at a position near the ceiling surface). Therefore, the airflow supplied from the upper outlet into the room is carried to the corners of the room along the ceiling surface by the Coanda effect. Then, during cooling, the cold air thus conveyed along the ceiling surface descends from the ceiling surface into the room, whereby the room is uniformly cooled. If the lower outlet is located near the floor, the Coanda effect can be used to carry the airflow to every corner of the room along the floor, as described above. The warm air carried along rises from the floor surface into the room, so that the room is uniformly heated.

Further, since the floor-standing type FCU of the present invention has the suction port provided on the front side of the machine body, by placing it in the room with the back side being in close contact with the wall, the amount of protrusion from the wall surface is minimized. In addition to being able to suppress the use of the indoor space effectively, it also has the advantage of reducing the feeling of pressure on the occupants.

Further, in the damper used in the floor-standing type FCU of the present invention, the ratio of the air sucked from the suction port to the upper air outlet and the lower air outlet can be set arbitrarily. In other words, the upper and lower outlets are not dedicated to cooling or heating. Therefore, in either case, it is possible to finely adjust the air condition by freely adjusting the blowout ratios from the upper and lower outlets.

[0010]

[Embodiment of the invention]

 The floor-standing FCU of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1A is a front view of a floor-standing FCU 10 according to the first embodiment of the present invention, and FIG. 1B is a side view thereof.

The floor-standing FCU 10 has a slender columnar airframe extending from the floor surface 100 to the ceiling surface 101, and has a downward air outlet 13 in the front thereof near the lower edge of the airframe (that is, near the floor surface 100). Is provided, and a suction port 11 is provided at a position above it. In addition, upper air outlets 12a and 12b are provided on the front surface and the side surfaces near the upper edge of the airframe (that is, near the ceiling surface 101). A similar outlet 12b is also provided on the side surface opposite to the side surface shown in FIG. 1 (b).

The air that has flowed into the machine through the suction port 11 provided on the front surface of the machine body passes through the filter 14 and the heat exchanger 15 to be heat-exchanged. Then, it passes through the meandering muffling mechanism section 16 to reach the blower 17, and further passes through the similar muffling mechanism section 17 to move to the upper side of the machine body. Here, the ventilation passage is branched in two directions, and a damper 19 is provided at the branch portion 25. The damper 19 can be set at any position between the first closed position shown by the broken line (I) and the second closed position shown by the broken line (II) in the figure.

When the damper 19 is in the first closed position (I), all of the airflow that has passed through the blower 17 and reached the branch portion 25 moves into the flow path 21 that goes downward on the rear surface side of the airframe, It is supplied indoors from the lower outlet 13. When the damper 19 is in the second closed position (II), all the airflow reaching the branch portion 25 is supplied to the room through the upper outlets 12a and 12b located right above it.

At the time of heating, it is preferable to set the damper 19 to the first closed position (I) so that all the airflow (warm air) is blown out from the lower outlet 13. Conversely, during cooling, it is preferable to set the damper 19 to the second closed position (II) so that all the airflow (cold air) is blown out from the upper outlets 12a and 12b. However, as described above, the position of the damper 19 can be set to an arbitrary position between the first closed position (I) and the second closed position (II), and therefore, for example, rapid heating at the start of operation. Alternatively, when rapid cooling is desired, it is also possible to adjust the blow rates from the upper and lower outlets and blow simultaneously.

As shown in FIG. 1, since the upper outlets 12a and 12b are present in the vicinity of the ceiling surface 101, the airflow from the upper outlets is distributed in every corner of the room along the ceiling surface by the Coanda effect. Is carried to. Then, during cooling, the cool air carried along the ceiling surface descends from the ceiling surface into the room, so that the room is uniformly cooled. Further, in this embodiment, since warm air can be blown out along the floor surface 100 during heating, the warm air is similarly spread along the floor surface to every corner of the room by utilizing the Coanda effect. be able to. Further, as can be seen from the figure, since the suction port 11 is provided on the front side of the body of the FCU 10, the FCU 10 can be arranged indoors with the back surface thereof in close contact with the wall surface 102. Therefore, the amount of protrusion from the wall surface can be minimized, the indoor space can be effectively used, and the pressure on the occupants can be reduced.

FIG. 2A is a front view of a floor-standing FCU 30 according to the second embodiment of the present invention, and FIG. 2B is a side view of the same.

The FCU 30 differs from that of FIG. 1 in that a flow path 31 from the branch portion 35 to the lower outlet 33 is provided on the front side of the body (the inner side of the front panel 32). . Along with this, the lower outlet 33 is provided above the suction port 34.

In the example shown in FIG. 2, since the flow path 31 from the branch portion 35 to the lower outlet 33 is provided on the front side of the machine body, it is necessary to provide a heat insulating material on the inner surface of the front panel 32. If omitted, the front panel 32 can also function as a radiation panel during heating, and energy efficiency can be improved.

Further, since the lower outlet 33 is provided above the inlet 34 and keeps a certain distance from the floor 100, the warm air from the outlet 33 is above the floor. It also has the advantage that it does not wind up dust.

FIG. 3 (a) is a front view of a floor-standing FCU 40 according to the third embodiment of the present invention, and FIG. 3 (b) is a side view thereof.

This FCU 40 is a modification of the FCU 10 of FIG. 1, and employs a bunker louver 41 having a variable wind direction in the upper outlet, instead of the graded grill. By adopting the bread louver, the airflow blown along the ceiling surface 101 can be carried further. Incidentally, it is of course possible to employ a punk rubber for the FCU 30 shown in FIG.

In each of the embodiments described above, only the upper air outlet is provided on the front surface and both side surfaces of the machine body, and the lower air outlet is provided only on the front surface of the machine body. The air outlets may also be provided on the front surface and both side surfaces of the machine body.
