Abstract

PURPOSE: To eliminate the need for ventilation in a room, to reduce an air flowing power, to eliminate heating in an air conditioner in winter and to provide energy conservation by providing a water humidifier at the inlet of an air cooler. CONSTITUTION: The air in a room fed to an air cooler 1 is supplied to a clean room through a water humidifier 3, a cooling coil 4 and a blower 5. In the cooler 1, the humidifying amount of the humidifier 3 is controlled by a humidity sensor 8 near a suction port 2, a humidity regulator 9 and a two-way valve 10. In winter, only necessary atmospheric amount is dehumidified by a filter to cool the atmosphere. The water humidifying of the cooler 1 is also useful to reduce the air flow rate. The supply water is cascade fed from the coil 4 to the humidifier 3, thereby improving the functions of the coil 4 and the humidifier 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner (hereinafter referred to as an air conditioner), and more particularly to an air cooling device for performing cooling throughout the year.

[0002]

2. Description of the Related Art Conventionally, this type of device has been operated by an air conditioner installed outdoors. However, in such a system, although cooling is performed throughout the year, cooling, heating, and humidification are performed inside the air conditioner during the winter. In addition, part of the air in the room is ventilated and the outside air is mixed to air-condition.

As described above, while air conditioning is required in the room, in the air conditioner, the outside air and ventilation are mixed and heated for humidification, resulting in a large energy loss.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the prior art, to eliminate ventilation in a room, to reduce blast power, to eliminate heating in an air conditioner in winter, and to save energy. It is in.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a fan coil unit comprising a coil, a blower, and a casing incorporating the coil, and by adding a water humidifying function to the inlet of this unit, cooling and humidifying the room throughout the year. Let it be done in-house.

[Examples] Examples will be described below with reference to the drawings. FIG. 1 is a sectional view of an air cooling device of the present invention to which a water humidifying function is added, FIG. 2 is a clean room air conditioning system using this cooling device, and FIG. 3 is a schematic sectional view showing a conventional clean room air conditioning system.

The room air flowing into the air cooling device 1 is sent to the clean room 17 through the water humidifier 3, the cooling coil 4 and the blower 5. In the air cooling device 1, the humidity amount of the humidifier 3 is controlled by the humidity sensor 8, the humidity controller 9, and the two-way valve 10 near the intake port 2.
The temperature is the temperature sensor 4 in front of the blower 5 and the temperature controller 1
It is controlled by the two-way valve 13. Because the cooling device 1 performs humidification in winter and heat treatment generated in the clean room throughout the year, the air conditioner 18 only has a function of treating outside air. Especially in the winter season, only the required amount of outside air is removed by the filter 21 and introduced into the clean room 17, whereby the outside air can be cooled. Further, the water humidification of the air cooling device 1 also has a cooling function,
It is also useful for raising the temperature of water supply and reducing the amount of air blown by the cooling device.

Further, by supplying the supply water from the cooling coil to the humidifier in a cascade, cold water is supplied to the coil,
After that, the humidification is performed and the functions of the cooling coil and the humidifier can be improved.

[0009]

As described above, according to the present invention, it is possible to reduce the blast power of the air conditioner and to eliminate the heating of the air conditioner in winter, and it is possible to achieve a great energy saving.
