Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant having a room (industrial clean room) for producing electronic materials and electronic components such as semiconductors and liquid crystals, and a large heat load in a room such as a computer room. The present invention relates to a humidifying facility for air conditioning that can be suitably used for a building having a room required to have a predetermined humidity and cleanliness.

[0002]

2. Description of the Related Art In Japan, since the humidity of air in winter and the middle season is lower than the humidity required in the above-mentioned room, it is necessary to compensate for the lack of humidity of air introduced for ventilation in this season. Heating and humidification processing is performed on the introduced air by a processing air conditioner (external air conditioner), and cooling and dehumidification are performed by the external air conditioner in the hot and humid summer season. For example, JP-A-9-796
In the apparatus of JP-A-11, a water atomizer is arranged on the upstream side in the external conditioner, and a steam ejector is arranged on the downstream side, and coils for passing a high-temperature medium in winter are arranged before and after the water atomizer. In the season when the outside air is at low temperature and low humidity, the coil is heated to high temperature to heat the outside air and the spray, and furthermore, the steam ejector is operated to humidify.

[0003] In the above-mentioned industrial clean room, the equipment installed in the room generates a large amount of heat. On the other hand, workers are sparsely arranged compared to the area of the room, and the rise in humidity is relatively small. The air conditioner controls the humidity in addition to the supply air temperature using an external air conditioner, and avoids humidifying and dehumidifying the circulating air circulating in the room. I was However, when dew condensation occurs in the air cooler, a dehumidifying effect occurs.Therefore, a dry heat exchanger that prevents dew condensation is used as the air cooler, and there are many cases where the amount of cold water passing through the air cooler is reduced and the air cooler is operated. Was not good.

When a humidifier is incorporated in an external air conditioner in such a facility, the temperature of the outside air is low in winter and riding on the humidifier is poor. To improve this, the temperature of the outside air is increased by an air heater. However, the size of the device is correspondingly large, and a large installation space is required. Without this air heater, the humidification system freezes due to low temperature outside air, and for example, the spray pipe may be ruptured. When the humidifier incorporated in the air conditioner is a water humidifier, it is necessary to once heat the air with an air heater, but the entire room has a waste of energy of cooling against heat generation. .

[0005] In many large computer centers, the humidifier is often provided in an air conditioner for controlling the temperature of circulating air in a building, instead of an external air conditioner. This is because, for a computer, drying causes serious troubles due to static electricity damage and other problems, but the amount of outside air taken in is smaller than the amount of circulating air, and the amount of humidification is limited. The same applies to communication devices such as a digital PBX.

As a humidifier used in a computer center, an electrode type humidifier is generally used, and humidifier must be constantly humidified when a large amount of circulating air is flowing. Therefore, the humidifier requires a large amount of electric power. If the humidifier has a failure, the air conditioner equipped with the humidifier must be shut down for repair and replacement. It was necessary to take measures such as installing a separate machine.

[0007] The facilities such as the factory, the computer center, etc.
Unlike ordinary offices, the power consumption is extremely large, and the consumption of fossil fuel for power production is large,
Energy conservation is a major concern for business operators, and administrative guidance has been given to promote it from the viewpoint of global environment.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the size of an external controller without reducing the humidifying function of the entire equipment, to reduce power consumption, and to check and replace the humidifier for an air conditioner.

The feed pipe 62 and the return pipe 63 are connected to bypass pipes 65 and 66 for bypassing the condenser 53, and each pipe is provided with a valve 67, 68, 69 and 70.

In this device, when the air conditioner 45 is operated, the circulating air flows upward from the underfloor space 11 to the computer room 4.

Open the valves 61 and 62, open the valves 67 and 68 on the condenser side,
The valves 69, 70 are closed and activated. Then, the evaporator 52
The water cooled by the bypass pipe 58 and the aftercooler 4
8. It flows through the bypass pipe 57 and cools the aftercooler 48 strongly. When the valves 59 and 60 are opened and the valves 62 and 61 are closed, the cold water in the water heat storage tank 40 is cooled by the evaporator 52, so that a large amount of cooling water can be produced and stored. Then, when the refrigerator is stopped and the valves 62, 61, 60, 59 are opened, the aftercooler 48 can be cooled by consuming the cold heat of the cold water in the water heat storage tank 40.

If the step of producing and storing the cooling water is performed at night when the wet-bulb temperature of the outside air decreases and the enthalpy decreases, the cooling efficiency of the condenser increases. If the step of consuming the cold heat of the cold water is performed in the daytime, the cold heat can be effectively used, and the energy consumption can be reduced. Furthermore, an operation method in which the refrigerator is operated again when the amount of heat stored in the water heat storage tank is reduced and the cold water from the refrigerator is guided to the dry heat exchanger can be exemplified.

In the low temperature season, the valves 67 and 68 on the cooling tower 54 side are closed without operating the refrigerator, and the valves 69 and 7 are closed.
Opening 0, the cooling water 64 can be air-cooled by operating only the water spray 54a and the fan 54b and sent to the pre-cooler 49 to perform a cooling operation, and energy consumption can be saved because the refrigerator is not operated. .

In order to distribute cold water as described above, it is necessary to attach a pump to an appropriate pipe and control the operation of the pump in accordance with the switching of the valve. Although not shown, the pump is provided in, for example, pipes 56, 58, and 63. When the coolers 48 and 49 are replaced with a single dry heat exchanger, the dry heat exchanger is connected to the bypass 57 and 58 and the bypass 6.
What is necessary is just to make it connect by switching 5 and 66 side by a valve.
