Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention is applicable to hotels, condominiums,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outside air introduction type fan coil unit that constantly supplies outside air with a constant wind speed and air volume to a room such as a patient room that requires fresh outside air at the same time as the supply of cool and warm air.

[0002]

2. Description of the Related Art Usually, as a means for cooling and heating the inside of a hotel or the like, an air conditioner installed on the indoor ceiling or the like is operated to heat the indoor air introduced into the machine to a proper temperature by a heat exchange coil, Air is blown into the room to cool or heat the room. However, the cooling only by the indoor air, the heating ventilation is not good for the health environment because it contaminates the indoor air significantly, and recently, the outdoor air is taken in at the same time as the indoor air is fed, and the indoor air is cooled by the mixed air with the outdoor air, There was heating.

[0003]

As a means for introducing the outside air, the usual mechanism is to connect a blow passage formed in the machine and a blow passage for the outside air, and combine the recirculated air from the room with the introduction of the outside air. Or, it has been required to send cold or warm air of a desired state by the action of switching the air passage by the damper mechanism, etc. Since, for example, when the wind speed is lowered by the condition inside the room, the amount of external air is also reduced with the decrease in the amount of cold and warm air. It was completely impossible to introduce only extraneous fresh air into the room. In other words, the wind speed of the outside air that is to be introduced into the room is always the same as the wind speed and the air volume of the cold and warm air that is delivered to the room, and is unchanged. It is difficult to deliver the required amount of the fuel to the average, and especially when using the conventional machine, it is not possible to deliver fresh outside air to every corner of the room completely reliably because of the above. It had the drawback of.

[0004]

The present invention was developed in view of the above-mentioned drawbacks, and its outline will be described with reference to a ceiling-mounted fan coil unit for indoor installation in a hotel or the like. A suction port 3 and a blow-out port 4 are provided on both sides of a lower panel 2 which is vertically downwardly connected in series, and a blow-out port 5 having a blow-out grill 10 is provided in front of the machine body 1, and a blower 6 is provided in the machine. In a cassette type fan coil unit in which various mechanical devices such as a heat exchange coil 7, a drain pan 8 and a humidifier are arranged, an outside air intake port 9 is provided in a part of the machine body 1 and the outside air intake port is provided. 9 and above,
The outside air introduction type fan coil unit is characterized in that an outside air blowing passage B communicating with the front air outlet 5 is formed in parallel with the cool and warm air blowing passage A formed in the machine.

[0005]

In the fan coil unit according to the present invention, the lower panel 2 faces downward on the ceiling of the entrance corridor of a hotel or the like,
The front blowing grille 10 side is installed indoors with the ceiling hanging. By operating the blower 6 in such a state, the room air is introduced into the cool / warm air blowing passage A in the machine from the suction port 3 on the lower surface of the machine body 1, and this is heated by the heat exchange coil 7 to an appropriate temperature. On the other hand, the air is supplied as cold and warm air of a predetermined temperature from the lower air outlet 4 and the front air outlet 5a into the room. Further, regardless of the above operation, since the present invention forms the outside air blowing passage B inside the machine, the fresh outside air whose wind speed can be adjusted in advance by the terminal air conditioner to be installed through another duct, It is possible to guide the air from the outside air intake port 9 through the outside air blowing passage B, and to send the air from the outside air outlet port 5 to a required place in the room at a constant wind velocity and air volume.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. The drawing shows a fan coil unit for indoor installation in a hotel or the like, in which 1 is a lower panel 2 which is vertically adjustable so as to be vertically adjustable. In the body of the fan coil unit, a suction port 3 and a blow-out port 4 having appropriate widths are provided on both sides of the lower panel 2. The lower panel 2 is attached to the lower side of the machine body 1 so as to be openable and closable, and the lid is opened to facilitate maintenance work inside. Further, a blow-out grill 10 having a blow-out port 5 is attached to the front portion of the inside of the machine body 1 so as to be movable back and forth, and the suction port 3 is provided.
The lower air outlet 5 and the lower air outlet 5 are connected and communicated with each other through the cool and warm air blow passage A, and the blower 6, the heat exchange coil 7, the drain pan 8 and other necessary mechanical devices such as a humidifier and a valve are arranged in the blow passage A. . According to the present invention, in the fan coil unit having the above structure, an outside air intake 9 for connecting the duct a is provided at an appropriate position such as a side portion of the machine body 1, and the outside air intake 9 and the front air outlet 5 are connected to each other. An outside air blowing passage B is provided separately from the above-mentioned cold / warm air blowing passage A so as to pass therethrough.

[0007] As another construction, an outlet 5 for cold and warm air is provided in an outlet grill 10 attached to the front part of the machine without opening the outlet 4 in the lower panel 2 and the outlet 5a is provided. It is also a consideration to open the outside air outlets 5 in parallel and in the same front. Further, the present invention is not limited to the above-mentioned fan coil unit for ceiling suspension, and can be widely used for other indoor air conditioners such as a floor installation type by utilizing the structure.

[0008]

As described above, according to the present invention, the outside air blowing passage B is formed separately from the cooling / warming blowing passage, so that the feeding of cold and warm air and the outside air are not mixed as in the conventional case. It is possible to deliver only the outside air to a required place in the room at a constant wind speed and volume. Therefore, it is possible to reliably and completely supply the required amount of outside air regardless of the strength of the cold / warm air supply, and of course, even if the cold / warm air supply operation is stopped, only the outside air is supplied to the entire room. It has the effect that it can be sent over.

Further, as described in claim 2, by opening the indoor cool / warm air outlet 4 and the outside air outlet 5 on the same surface, the outside air can be supplied simultaneously with the supply of the cold and warm air into the room. It is possible to feed in the same direction, and the structure in which the above-mentioned cold / warm air blow passage A and outside air blow passage B are installed in the same fuselage makes the whole fuselage compact and can immediately respond to equipment currently in use. It also has economic effects such as obtaining.
