Description

[Detailed description of the invention] This invention is a fan coil unit for air conditioning. To provide a ceiling-suspended outside air intake type fan coil unit that cools outside air by blowing and exhausting air.

Conventionally, fan coil units installed under windows near external walls are
It is used in hotel rooms, hospitals, five private rooms in dormitories, etc., but it is difficult to install if there is not enough space on the floor next to the outside wall, and even if it can be installed, the effective floor and area will be smaller. There was a drawback.

In addition, for energy saving and health reasons, air conditioning is performed at night during the summer using colder outside air.
It was desired to shorten the operating time of the refrigerator and maintain a comfortable indoor environment.

The fan coil unit according to the present invention solves the above-mentioned drawbacks.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

As shown in Fig. 1, the fan coil unit 1 according to the present invention is suspended from the ceiling 2 on the indoor side, and the outside air intake port 3 of the fan coil unit 1 is installed between the ceiling and the beam in the middle hallway. It communicates with the outside air chamber 4, and the exhaust port 5 communicates with the middle hallway.

This fan coil unit 1 includes a casing 6,
Outside air intake/return air switching mechanism section 7. It includes a fan 8 and a coil unit 9.

The outside air intake/return air switching mechanism 7 includes a partition wall 10 and a partition wall 1.
The blade 11 is rotatably provided at the inner end of the blade 1.

A partition 10 separates an upper fresh air intake compartment 12 and a lower exhaust compartment 13 from each other.

The rotating blade 11 is a return air/exhaust blade 11 that rotates within the upper outside air intake section 12 as shown in FIG.
It consists of b.

Each blade is an elongated rectangular plate member,
The outside air blade 11a is provided with a small outside air intake port 15 so that a minimum amount of outside air can be taken in when indoor air is returned during cooling and heating as described below.

Blades 11a and 11b have an internal angle of 13
The angle is such that the external angle of 5° is 225°, and it is designed to rotate between the position shown in FIG. 2a and the position shown in FIG. 2S.

Hereinafter, the operation of the fan coil unit will be explained based on the embodiments shown in FIGS. 2a and 2s.

When the blade 11 is in the position shown in FIG. 2a and cooling or heating is performed, indoor air passes through the indoor air intake port 16 provided at the bottom of the switching mechanism 7 and is directed to the fan 8 in the direction of the arrow. The air is drawn into the room from the outlet on the side of the casing 1 after being cooled or heated by passing through the coil section 9 in which the refrigerant or hot medium is circulated. ．． indoors,
Inlet 16, fan 8. It will circulate through the coil section 9.

In this case, as described above, the external blade 11a is provided with the minimum outside air intake port 15, so that the minimum amount of outside air is taken in from there.

Next, when the temperature of the outside air decreases and cooling by the coil section 9 is no longer necessary, the blade 11 is rotated counterclockwise 90°.
° rotate, place the outside air blade 11a on the partition wall 10,
Position it as shown in Figure 2.

As is clear from Figure 2, the upper outside air intake section 1
2 communicates with the fan 8 and the indoor air intake section 1
4 communicates with the exhaust section 13, so that the outside air in the outside air chamber 4 on the ceiling below the middle circumference passes through the outside air intake section 12 as shown by the arrow and is drawn into the fan 8, and the coil section 6
The air passes through the air outlet 17 and is blown into the room.

In this way, a large amount of cooled outside air can be blown into the room.

In the above, the case where the blade is located at the position shown in FIG. 2a or FIG. It is also possible to fix it to

According to the fan coil unit of the present invention, it is possible to cool the outside air when the outside temperature drops, such as at night or during the middle of the summer, so the operation time of the refrigerator is shortened, energy is saved, and the machine Because indoor air conditioning does not dry out the indoor air, it does not have any negative effects on health.

It also has the advantage of being suitable for settings where there is no floor space, where the system is affected by exhaust air from adjacent buildings, or where wind pressure is required in high-rise buildings.
