Indirect Cooling in Data Centers

Modern data centers are remarkably technologically complex, and keeping them running safely and efficiently requires continual close monitoring and management.

Maintaining the correct temperature is among the most important tasks faced by data center managers. Should the temperature and humidity rise to excessive levels inside the data center, condensation can start forming, damaging the machines within. This can cause massive damage and disruption, so it must be avoided at all costs. Fortunately, various technologies are on hand that can help keep data center temperatures at the right level.

There are numerous ways to cool a data center. Indirect air cooling uses external air, but by including an air-to-air heat exchanger, the outside air is kept in a separate loop, providing cooling without entering the server room.

Indirect cooling methods benefit by not contaminating the inside air with outdoor air pollutants and humidity. A heat exchanger keeps both airstreams separated while transferring the heat from the inside to the outside of the data center building. Consequently, the ambient and indoor air never mix.

Dry cooling is usually sufficient if the data center is located in a consistently low-temperature area, meaning no water is involved. However, by spraying water on the ambient air side of the heat exchanger, an evaporative effect is achieved, resulting in a lower indoor air temperature. This method is called indirect evaporative cooling (IEC).

Ideally suited for warm, dry climates, IEC provides excellent cooling potential with low operational- and first-cost. Ambient temperature reductions of 6-8 °C (10-15 °F) are typical in summer conditions. IEC provides up to 28% in energy savings compared to conventional free cooling and 52% to air-cooled Free Cooling alternatives.

Evaporative cooling requires a plate heat exchanger that balances high efficiency with low pressure drop, offers solid corrosion protection, and reliable water tightness. Cross-flow heat exchangers meet all these requirements while providing outstanding cooling capacity.

Our crossflow heat exchangers, especially with evaporative cooling technology, provide an efficient, low-cost, and environmentally friendly alternative to traditional cooling methods.

A rapid method for eliminating white smoke

白煙を素早く除去する方法

The principle of using a condenser for dehumidification to eliminate white smoke is mainly based on the physical changes of water vapor in the flue gas. The condenser cools the flue gas with low-temperature water or air, gradually reducing its temperature, and the water vapor inside begins to condense into small water droplets. These small water droplets gather inside the condenser and eventually form liquid water, which is then removed through drainage pipes. Dehumidification through a condenser is an effective technical means to eliminate white smoke. It can not only reduce visual pollution, but also help improve the operational efficiency and energy-saving effect of environmental protection equipment. We can provide you with a suitable dehumidification solution for flue gas, which is both economical and environmentally friendly. Welcome to consult us via email.

Efficient equipment for removing industrial flue gas

産業排ガスを除去するための効率的な装置

熱交換技術を用いた産業用排ガス脱硫装置は、排ガス中の水蒸気含有量を低減し、煙突からの排出時に発生する白煙を除去します。排ガスの白化には、主に以下のような方法があります。

排ガス加熱技術：脱硫された湿潤排ガスを熱交換器を通して工業用高温排ガスと熱交換させることで、排ガスの排出温度を上昇させ、排ガスの相対湿度を低下させ、水蒸気の凝縮による白煙の発生を防止します。この方法は白煙の発生を効果的に低減できますが、煙を加熱するためにある程度のエネルギーを必要とします。

排ガス凝縮技術：まず飽和排ガス中の水蒸気を部分的に凝縮し、その後排ガスを加熱します。この方法は、排ガス中の水分含有量を低減することで白煙の発生を抑制するとともに、水資源の一部を回収します。

MGGH技術：電気集塵機の前後に排ガス冷却熱交換器を設置し、脱硫装置後に排ガス加熱熱交換器を設置し、熱媒水循環システムを構築する。この技術は、元の煙から熱を抽出し、清浄な煙を加熱する。通常、白煙の発生を防ぐため、清浄な煙の温度は75～80℃に上昇させる必要がある。

まとめると、これらの方法はそれぞれ長所と短所があり、異なる産業環境やニーズに適しています。特定の排ガス脱硫技術を選択する際には、プロセス条件、廃熱源、投資要件などの要素を考慮する必要があります。メールでのご相談をお待ちしております。

スモークスクラバー：物理的な方法で白煙を効率的に除去

The smoke scrubber condenses water vapor in the flue gas into liquid through a condenser, and gas pollutants adhere to the condensed liquid before being discharged through exhaust gas. This technology does not require a collector, but relies on the precipitated liquid to carry away pollutants, thereby reducing operating costs and minimizing the environmental pollution caused by white smoke.

Mainly used for desulfurization and whitening of flue gas from coal-fired boilers, gas-fired boilers, power plants, metallurgy and other industries.

Energy saving devices for heat dissipation in computer rooms

The heat exchange core of the computer room's heat dissipation energy-saving device is an efficient heat dissipation solution specifically designed for data centers or server rooms. By optimizing heat exchange efficiency, energy consumption can be reduced and system performance can be improved.

During the heat exchange process, the hydrophilic layer can effectively increase the heat exchange area and improve the heat exchange efficiency. Adopting a multi-layer microchannel design increases the contact area between the fluid and the metal wall, thereby improving the heat transfer efficiency. Greatly improved the energy efficiency ratio of data centers and reduced operating costs.
