2. Description of the Related Art Usually, most of the fan coil units of this type have a function of supplying a predetermined amount of cold and warm air to the room in each of the different directions of the upper and lower blowouts. In recent years, some fan coil units have been developed that blow the above and below air at the same time or separately from each other.Both of these units have cooler air, such as cool air or warm air, at a constant temperature. However, because warm air is blown out at the same time, due to the relationship of population density or the sunshine-shaped body, the indoor middle layer part is abnormally heated, while the foot part is cooled and head heat There are many cases in which the environment becomes the worst, which causes discomfort in the room.

[0003]

SUMMARY OF THE INVENTION The present invention immediately solves the above-mentioned abnormal condition of cold and warm air by simply changing the adjusting means of a wind-flow changing damper, and as far as it is possible especially in the winter season, the vicinity of the floor surface can be solved. Alternatively, by centrally delivering warm air to the lower part of the indoor middle layer, it is possible to raise an effective heating function of the head cold foot heat type, and to provide a floor-mounted fan coil unit that can form a low overall shape. The main purpose is to

[0004]

As means for achieving the above object, the present invention is directed to an indoor air suction port 2 on one back side of an upper panel b of an airframe 1, an upper air outlet 3 to the front, and a front panel. A lower outlet 4 is provided near the lower floor surface of a, and an N-shaped back portion is formed in the machine by several separating plates c and d.
Central and front air passages 5, 6 and 7 are formed, a filter 8 and a blower 10 are installed in the back air passage 5, and a cold and hot water coil 9 is erected in the central air passage 6, and the front surface is further provided. An airflow switching damper 11 is arranged in the panel a on the front side of the cold / hot water coil 9 so as to be able to switch between the upper and lower air passages, and the cold air from the cold / hot water coil 9 is fed from the upper outlet 3 to the intermediate layer in the room. The warm air is configured to be easily fed from the lower outlet 4 to the vicinity of the floor below the floor, that is, the optimal head-and-foot type blower.

Further, the blower 10 installed in the back blower passage 5 by the above mechanism has the discharge port 10a opened in the central blower passage 6 for the purpose of silencing, or the room temperature for presetting the airflow switching damper 11. It is connected to a sensing device such as the above, and the wind flow switching damper 1 is selected according to the room temperature.
In addition to the structure in which the wind flow of No. 1 is automatically movable so that it can be moved up and down, a silencing material 12 having an appropriate thickness is attached inside the front panel a to obtain a more effective silencing effect. It is configured to be.

The operation of the floor-mounted fan coil unit according to the present invention will be described below. The airframe 1 is installed close to a wall surface, a glass surface, etc. in the room. For example, in the winter season, the blower 10 is operated. Air from the room is sucked in through the upper suction port 2 and flows into the back blower passage 5 and flows from the central blower passage 6 to the front blower passage 7, while the cold and hot water coils 9 perform heat exchange to an appropriate temperature. As you can see, the cold wind is at the top,
Cold air is blown from the air outlet 3 by adjusting the wind flow switching damper 11 up and down to send warm air downward, and warm air is blown from the lower air outlet 4 to the lower floor of the indoor floor at the same time. It is possible to obtain an ideal heating action called a shape, and further, depending on the adjustment of the air flow at the upper outlet, the warm air that can be sucked from the inlet 2 blows upward from the upper outlet 3, and this rises again. Reverse U to return to
To form a circuit having a shape, that is, to prevent clouding on the glass surface or the like for flowing in the vicinity of the wall surface or the glass surface,
It also has the function of removing the adhesion of dew.

Further, in the present invention, not only the upper and lower air distribution of the blown air, but also the air volume can be easily changed and adjusted by vertically moving the air flow switching damper 11, and each time according to the environment in the room. It also has functions such as optimum temperature, cooling and warm environment depending on air volume, which can be freely obtained.

Further, by connecting the wind flow switching damper 11 to a preset room temperature sensing mechanism or the like, ideal automatic management according to the indoor environment is possible.
