Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE devised, cooling using a humidifier
Cooling with the central air-conditioning system and cooling with a large amount of dehumidification
It relates to a combined humidification and cooling device.

[0002]

2. Description of the Related Art A conventional cooling device performs heat exchange of air with an air conditioner by supplying a refrigerant at about 7 to 10 ° C.
A cold air of about 20 ° C. is produced, blown out into the room, and a sensible heat and a latent heat load of the room are removed, thereby creating a room air condition that is a comfortable environment for the occupants.

[0003] The amount of heat required for cooling is the product of the temperature difference between the room temperature and the air cooling air temperature and the air blowing amount, and the temperature difference between the room temperature and the air cooling air temperature is only about 10 ° C. Therefore, it was unavoidable that the air volume would be excessive. For this reason, the size of the transport equipment such as the blower and the duct was inevitable.

[0004]

In order to suppress an excessive amount of air to be blown, there is a method in which the temperature of a refrigerant supplied to an air conditioner is lowered, low-temperature air is blown into a room, and the temperature difference is increased. However, the amount of heat to be removed by the cooling operation in a normal living room is, in spite of the overwhelming amount of sensible heat, the operation by only low-temperature blow-off, because the latent heat is excessively removed (that is, the air is cooled to remove moisture). Air) is in a dry state, and there is a problem that the indoor humidity is out of the range where the occupants are comfortable.

In this invention, a water humidifier is installed and operated on the outer periphery of a chamber having a high sensible heat load ratio.
The room was in a comfortable air condition. Further, since water humidification has a cooling effect associated with evaporation, the function of promoting cooling by air blowing can further reduce the amount of air blowing.

1 is an explanatory view of the arrangement of a humidifying and cooling device according to the present invention, wherein 1 is an air conditioner, 2 is a heat exchanger between air and refrigerant, 3 is a blower for air circulation, and 4 is a supply fan. Air duct, 5 is an air outlet, 6 is a room to be cooled, 7 is a return air duct, 8 is a water humidifier provided on the outer periphery of the room, 9 is an outside air intake duct, 10 is outside air, and room air that has recirculated. It is a mixture part with. In this invention, the temperature of the refrigerant to the heat exchanger 2 is set to 0 to 4 ° C., the heat exchange efficiency of the coil is increased, the amount of air blow is reduced, and the temperature of the air discharged from the air conditioner is set to 0 to 10 ° C. The difference between the room air temperature and the room air temperature is 20 ° C. to 30 ° C. Since the temperature of the refrigerant is lowered and the temperature of the discharge air is lowered, the amount of air to be blown is small and the air is strongly cooled. It has become. The humidity can be increased by the water humidifier 8 and the indoor temperature can be further reduced by cooling by evaporation.

[0007] Due to the low-temperature blowing and a smaller amount of blown air than required, the indoor condition has a low relative humidity and the room temperature is high. However, a water humidifier 8 is provided on the outer periphery of the room 6 to reduce the indoor humidity. with raised, Ru lowers the temperature by evaporation. Immediately
In other words, to handle the indoor load of cold air discharged from the air conditioner
Humidification that simultaneously cools simultaneously with the accompanying temperature rise
Thus, the indoor temperature / humidity state is brought to a comfortable environment for the occupants .

[0008]

The invention of the present application has the above-mentioned structure and reduces the amount of circulating air. Therefore, it is necessary to reduce the size of the blower or the transfer equipment of the air conditioner, or to operate the transfer equipment. The energy consumption can be reduced, and the cost associated with them can be reduced.
