Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner suitable for air-conditioning a closed room having a large internal space such as a factory or a warehouse, and an air conditioner method using the air conditioner.

[0002]

2. Description of the Related Art Generally, an air conditioner is designed to heat or cool room air sucked from an air suction port to an appropriate temperature and blow it out from a blowout port to adjust the temperature of the room. .

[0003]

However, the conventional air conditioner has a drawback in that the temperature of each part in a room having a wide space such as a factory or a warehouse cannot be made uniform. Also, large-scale ducts
However, there is a drawback in that a large amount of equipment cost is required in order to make the temperature uniform by installing the equipment.

[0004]

Therefore, when the cause of the above-mentioned drawbacks was pursued, in the conventional air conditioner, since the air intake port and the air outlet port are arranged close to each other, the entire indoor air It was found that there was variation in the amount of circulation in each part without uniform circulation, and as a result, the temperature of each part in the room was non-uniform. The present invention has been made on the basis of the above-mentioned pursuit of causes, and the invention according to claim 1 includes an air suction port for sucking air in a sealed room, and an adjusting means for adjusting the sucked air to a predetermined temperature. , With an air outlet that blows out the air whose temperature is adjusted by this adjusting means in a substantially horizontal direction into the room,
The air intake port is arranged near the floor surface in the room, and the air outlet port is arranged near the upper end of the air-conditioned space in the room. The invention according to claim 2 is
Using the air conditioner, temperature-controlled air is blown out from the air outlet at a blowing speed of about 2.5 m / sec or less, and the air in the room is circulated a predetermined number of times or more per unit time. It is characterized by setting the amount.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, the air conditioning apparatus 1 includes an apparatus body 2 having a vertically long rectangular parallelepiped shape. Inside the device body 2, a fan 3 for sucking and blowing air, an adjusting means 4 having an oil or gas burner for heating and its heat exchanger, and a DX coil (adjusting means) for cooling.
5 is arranged, and the DX coil is connected to a compressor (not shown) arranged outside the chamber R. As the fan 3, the adjusting means 4, the DX coil 5 and the compressor, known ones are used. Further, in the case of this embodiment, the fan 3, the adjusting means 4, and the DX coil 5 are arranged in this order from the bottom to the top, but from the air suction port 6 provided in the apparatus main body 2, If the air is sucked in, heated by the adjusting means 4 or cooled by the DX coil 5, and then the heated or cooled air (hereinafter referred to as conditioned air) can be blown out from the air blowing port 7. , Their arrangement is arbitrary. The switching between cooling and heating is performed by operating a switch (not shown).

Although the above-described structure is similar to that of the conventional air conditioner, in this air conditioner 1, the intake port 6 and the blowout port 7 are arranged in order to make the temperature of each part of the chamber R uniform. Has been improved. That is, the suction port 6 is arranged at the lower end of the apparatus body 1 so as to be as close to the floor F as possible. On the other hand, the outlet 7
Is made as high as possible so that it can be positioned as close to the ceiling C (upper end of the air-conditioned space) as possible, and the outlet 7 is arranged at the upper end of the main body 1. There is. Further, the outlet 7 is formed so as to blow out the conditioned air in a substantially horizontal direction. In particular, in this embodiment, a louver (not shown) is provided at the outlet 7 so that the conditioned air can be blown out horizontally during heating and slightly upward during cooling.

Further, the suction port 6 and the blowing port 7
Are arranged and formed on all surfaces facing the inside of the chamber R so that the air can be sucked in as uniformly as possible from each direction of the chamber R and the conditioned air can be blown out uniformly in each direction in the chamber R. . For example, in the case of this air conditioner 1, since it is a type that is installed with the wall W as a back, the suction port 6 and the blowout port 7 are arranged and formed on the front surface and both side surfaces of the apparatus body 1, respectively. . Of course, in the case of the type installed in the center of the chamber R, it is preferable to dispose and form it on the entire front, rear, left and right sides of the apparatus body 2. In addition, in this embodiment, since the apparatus main body 1 has a rectangular cross section,
The suction port 6 and the blowing port 7 are formed on the respective surfaces, but when the apparatus main body 1 has a circular cross section, the suction port 6 and the blowing port 7 may be formed continuously in the circumferential direction. .

Next, the case where the temperature inside the room R is adjusted by the air conditioner 1 having the above-mentioned configuration will be described. First,
Air-conditioning apparatus 1 is activated by selecting cooling or heating. Then, the fan 3 sucks the air in the chamber R from the suction port 6 and heats it by the adjusting means 4, or D
The conditioned air cooled by the X-coil 5 is blown out 7
Is blown toward the inside of the room R. At this time, since the conditioned air is blown out in a substantially horizontal direction and the outlet 7 is arranged in the vicinity of the ceiling C, the conditioned air flows in the upper part of the room R and reaches the entire room R. On the other hand, since the suction port 6 is arranged in the vicinity of the floor F, the air in the entire lower portion of the chamber R flows along the floor surface and is gradually sucked. As a result, the air in the entire chamber R circulates uniformly. Therefore, the temperature of each part of the chamber R can be made uniform.

As described above, according to the air conditioner 1,
Although the temperature of each part of the room R can be made uniform, if the blowing speed and the air volume of the conditioned air are set as follows,
The temperature of each part of the chamber R can be made more uniform.
That is, the blowing speed of the conditioned air is set to about 2.5 m / sec or less, preferably 1.5 to 2 m / sec.
With such a blowing speed, the conditioned air blown from the blowing port 7 flows in a substantially laminar state, so that the conditioned air can be evenly distributed throughout the room R. On the other hand, the air volume of the conditioned air is set so that the air in the room R circulates a predetermined number of times per unit time. In this case, the number of circulations is appropriately determined according to the temperature difference between the inside and outside of the room R and the heat insulating condition of the building. For example, it is better to make a decision as shown in Table 1. Then, when the number of circulations is determined, the air volume of the conditioned air is appropriately determined in relation to the blowing speed.

The present invention is not limited to the above embodiment, but the design can be changed appropriately. For example, the above-mentioned air conditioner 1 is of a floor-standing unit type, but a suction port and a blow-out port may be formed in the wall F near the floor F and near the ceiling C, respectively.

[0011]

As described above, claim 1 or claim 2
According to the invention of the above, it is possible to obtain the effect that the temperature of each part in the room can be made uniform.
