Abstract

(57) [Summary] [Purpose] Reduce the amount of circulating air in the cooling system, reduce the size of conveyance equipment such as blowers and ducts required for air blowing, and reduce the energy consumption required for air blowing. [Structure] The refrigerant of the air conditioner in the cooling device is set to about 0 to 5 degrees Celsius, the temperature of the discharge air from the air conditioner is set to 0 to 10 degrees Celsius,
The air flow rate is such that the difference from the indoor air temperature is 20 to 30 degrees Celsius,
A water humidifier will be installed around the outside of the room.

[Detailed explanation of the idea]

0001

[Industrial application field]

This application relates to a central air conditioning type humidifying cooling device.

0002

[Conventional technology]

Conventional cooling equipment uses an air conditioner to exchange heat with air by supplying refrigerant at a temperature of about 7 to 10 degrees Celsius. Create cold air of about 15 to 20℃ and blow it into the room to reduce the sensible heat in the room. By removing heat and latent heat loads, indoor air conditions can be improved to provide a comfortable environment for occupants. was creating.

0003 The amount of heat required for cooling is the product of the temperature difference between the room temperature and the temperature of the cold air sent, and the amount of air blown. However, the temperature difference between this room temperature and the temperature of the cold air being sent is only about 10°C, so It was unavoidable that the wind volume would be excessive. Therefore, conveyance equipment such as blowers and ducts could not escape the increase in size.

0004

[Means to solve the problem]

To prevent excessive air flow, lower the temperature of the refrigerant supplied to the air conditioner and use low-temperature air. There is a method of blowing air into the room and increasing the temperature difference. However, the amount of heat that must be removed during normal air conditioning operation in a living room is overwhelmingly sensible heat. Regardless, operation using only low-temperature air blowing removes too much latent heat (immediately (to cool the air and remove moisture), the air becomes dry and the humidity in the room decreases. There is a problem where the situation is outside the range that is comfortable for the staff in the room.

[0005] Therefore, in this design, a water humidifier is installed and operated around the outer periphery of the room where the ratio of sensible heat load is high. By rotating the vehicle, the indoor air condition was brought to a comfortable range. In addition, water humidification has a cooling effect due to evaporation, so it helps cooling by air blowing. This function makes it possible to further reduce the amount of air blown.

【Example】

FIG. 1 is an explanatory diagram of the arrangement of the humidifying and cooling device of this invention, in which 1 is an air conditioner, 2 is an air conditioner; is a heat exchanger between air and refrigerant, 3 is a blower for air circulation, 4 is an air supply duct, and 5 is a blower. Outlet, 6 is the room to be cooled, 7 is the return air duct, 8 is the water humidifier installed on the outer periphery of the room, 9 1 is an outside air intake duct, and 10 is a mixture of outside air and indoor air that has been recirculated. In this design, the temperature of the refrigerant to the heat exchanger 2 is set to 0 to 5°C, and the heat exchange efficiency of the coil is Increase the rate and reduce the air flow to keep the temperature of the air discharged from the air conditioner between 0 and 10℃. The amount of air blown is set such that the difference from the indoor air temperature is 20°C to 30°C.

[0007] Due to the low temperature blowout and the lower airflow than required, the indoor conditions are low in relative humidity. Although the indoor temperature is high, a water humidifier 8 is installed on the outer periphery of the room 6 to reduce the indoor humidity. At the same time, it lowers the temperature through evaporation, bringing the indoor temperature and humidity to a comfortable environment. It is something that makes you

[0008]

[Effect of the idea]

The invention of this application has the above-mentioned configuration, and the amount of circulating air is reduced. Therefore, it is possible to reduce the size of conveyance equipment such as blowers and air conditioning equipment, and to reduce the size of conveyance equipment necessary for operation of conveyance equipment. It is possible to reduce energy consumption and the associated costs.
