Description

Information room cooling and energy saving method

The invention relates to a method for dissipating heat and energy of an information room, in particular to a method for separating the hot air of the information room from the cold air by using a partition plate, and matching the air temperature and air volume adjustment of the air conditioning device.

Referring to the ninth and tenth figures, the conventional large information room usually uses a so-called "displacement ventilation system" to obtain more efficient heat dissipation. The displacement ventilation is to send a low flow rate and low temperature wind from the vicinity of the floor. The airflow will slowly rise to the ceiling and replace the old air. The air in the machine room will be distributed in layers. The higher temperature air is mainly concentrated in the upper part of the machine room, while the cooler and fresher air is concentrated in the work. Area, but this kind of ventilation system causes the temperature distribution in the equipment room to be uneven, so that the temperature in the upper part of the equipment room is too high. The server installed in the upper part of the equipment room is more likely to be unstable due to the excessive temperature due to the temperature of the server installed in the lower part. , shutdown or even failures.

Another example is the "Energy Saving Information Cabinet" of the Republic of China Invention Gazette No. 201017382. The present invention relates to an information system built in an information room, which is specially designed for server, storage, network, computer system, etc. A cabinet, especially an internal airtight compartment device, is used to distinguish between a cold air and a hot air chamber. When the information system is in operation, the air conditioning system attached to the information room can be efficiently used to promote the energy saving of the information room. The carbon-efficient information cabinet is limited to the heat dissipation effect in a single cabinet, and the hot air in the cabinet is discharged to the equipment room. The hot air discharged to the equipment room is easily mixed with the cold air of the cooling cabinet, causing the temperature of the cold air to rise and decrease. To cool the high temperature of the cabinet, the air conditioner temperature must be lowered to achieve the originally expected cooling effect, resulting in poor heat dissipation in the equipment room and more power consumption, and increased electricity bills.

The invention utilizes the partition plate to separate the hot air generated by the operation of the cabinet in the information room from the cold air discharged from the air conditioner, avoids mixing of the hot air and the cold air, and recovers the hot air to the air conditioner, and converts the hot air by using heat exchange. Cool air is then discharged into the information room to achieve the best results of heat dissipation and energy saving.
