機(jī)柜空調(diào)和渦流管制冷器有什么區(qū)別？（中英文）
為封閉式電氣柜找到完美的冷卻解決方案并非易事。為了為企業(yè)做出正確的選擇，需要準(zhǔn)確的信息和最實(shí)用的支持來選擇機(jī)柜氣候控制系統(tǒng)，想知道機(jī)柜空調(diào)還是渦流管冷卻器更適合。以下是一些在選擇正確的電氣柜冷卻方法時(shí)需要牢記的重要考慮因素。
Finding the perfect cooling solution for enclosed electrical cabinets can be a challenge. To make the right choice for your business, you need accurate information and the most practical support in selecting an enclosure climate control system. You may be wondering whether an enclosure air conditioner or vortex tube cooler is right for you. Here are some of the most important considerations to keep in mind when deciding on the right way to keep electrical cabinet enclosures cool.
解決機(jī)柜冷卻難題
包含敏感設(shè)備的封閉式電氣柜在運(yùn)行過程中會(huì)產(chǎn)生極高的熱量。機(jī)柜或機(jī)柜冷卻系統(tǒng)可保持電氣和電子設(shè)備以最佳效率運(yùn)行，并防止過熱導(dǎo)致意外關(guān)機(jī)或損壞。現(xiàn)代冷卻技術(shù)的進(jìn)步使得在運(yùn)行過程中保持設(shè)備冷卻變得更加容易，并減少了因過熱引起的電氣和電子設(shè)備故障。
Resolving the Cabinet Cooling Conundrum
Enclosed electrical cabinets that contain sensitive equipment can generate extreme amounts of heat during operation. Enclosure or cabinet cooling systems keep electrical and electronic equipment running at peak efficiency and prevent overheating that could cause unexpected shutdowns or damage. Modern advances in cooling technologies have made it much easier to keep equipment cool during operation and reduce the number of electrical and electronic breakdowns caused by excessive heat.
什么是機(jī)柜式空調(diào)和渦流管冷卻器？
渦流管冷卻器和機(jī)柜式空調(diào)均設(shè)計(jì)用于在封閉區(qū)域內(nèi)工作，以冷卻電子設(shè)備和其他設(shè)備。然而，這兩個(gè)系統(tǒng)采用截然不同的運(yùn)行方式。
? 渦流管冷卻器將冷壓縮空氣注入封閉區(qū)域，無需運(yùn)動(dòng)部件和制冷劑，使其成為獨(dú)立、耐用且安靜的解決方案。
? 機(jī)柜式空調(diào)的工作原理與傳統(tǒng)空調(diào)系統(tǒng)類似。該方案需要壓縮機(jī)、蒸發(fā)器鼓風(fēng)機(jī)和冷凝器鼓風(fēng)機(jī)協(xié)同工作，將冷空氣集中在機(jī)柜內(nèi)并散熱。
What Are Enclosure Air Conditioners and Vortex Tube Coolers?
Both vortex tube coolers and enclosure air conditioners are designed to work in enclosed areas to cool electronics and other equipment. These two systems, however, use very different methods of operation.
? Vortex tube coolers inject cold compressed air inside the enclosed area, eliminating moving parts and refrigerant to make these units a self-contained, durable, and quiet solution.
? Enclosure air conditioners work similarly to traditional AC systems. This option requires a compressor, an evaporator blower, and a condenser blower working together to concentrate cool air in the cabinet and remove heat.
機(jī)柜式空調(diào)的工作原理
傳統(tǒng)的機(jī)柜式空調(diào)的工作原理與家用和商用中央空調(diào)大致相同：
? 首先，制冷劑氣體進(jìn)入壓縮機(jī)升溫。
? 接下來，制冷劑被輸送到冷凝器盤管，冷卻后重新變成液體。
? 然后，液態(tài)制冷劑被送至蒸發(fā)器盤管，吸收熱量，使蒸發(fā)器盤管顯著冷卻。
? 風(fēng)扇引導(dǎo)空氣流經(jīng)蒸發(fā)器盤管，冷卻蒸發(fā)器盤管，并產(chǎn)生冷空氣，冷空氣分布在整個(gè)機(jī)柜內(nèi)。
? 閉環(huán)機(jī)柜式空調(diào)從機(jī)柜中吸入熱空氣，并在熱量散發(fā)后將其送回機(jī)柜，而不會(huì)吸入環(huán)境空氣。這可以保護(hù)機(jī)柜免受灰塵或有害空氣顆粒的侵害，并實(shí)現(xiàn)高運(yùn)行效率。
How Enclosure Air Conditioners Work
Traditional enclosure air conditioners operate in much the same way as central air conditioning in homes and businesses:
? First, the refrigerant gas enters a compressor to raise its temperature.
? Next, the refrigerant is transferred to a condenser coil that allows the refrigerant to cool, which converts it back into a liquid.
? Then, the liquid refrigerant is sent to an evaporator coil where it absorbs heat, causing the evaporator coil to cool down significantly.
? A fan directs air across the evaporator coil to cool it and produce cold air that is distributed through the cabinet.
? A closed-loop enclosure air conditioner draws hot air from the enclosure and sends it back in once the heat has been removed, without ever pulling in ambient air. This protects the enclosure from dust or harmful airborne particles and provides high-operating efficiency.
渦流管冷卻器的工作原理
渦流管是渦流冷卻器系統(tǒng)的核心。該管將壓縮空氣壓入一個(gè)腔室，該腔室使空氣以極高的速度旋轉(zhuǎn)，轉(zhuǎn)速高達(dá)每分鐘一百萬轉(zhuǎn)。流動(dòng)較快的熱空氣會(huì)流到管外，并通過閥門排出。剩余的流動(dòng)較慢的空氣比進(jìn)入的空氣溫度低得多，會(huì)流入封閉區(qū)域。渦流管冷卻器系統(tǒng)可將溫度降低高達(dá) 100 華氏度（約 37 攝氏度）。
How Vortex Tube Coolers Work
A vortex tube is at the heart of a vortex cooler system. This tube forces compressed air into a chamber that spins the air at extremely high speeds, up to one million revolutions per minute. Faster-moving hot air moves to the outside of the tube and is released through a valve. The slower-moving air that remains is significantly cooler than the incoming air and flows into the enclosed area. Vortex tube cooler systems can lower temperatures by as much as 100 degrees Fahrenheit.
優(yōu)缺點(diǎn)
基于制冷劑的封閉式空調(diào)系統(tǒng)和渦流管冷卻器系統(tǒng)各有優(yōu)缺點(diǎn)。在選擇這兩種封閉式冷卻系統(tǒng)時(shí)，需要牢記的一些關(guān)鍵要點(diǎn)包括：
The Pros and Cons
Both refrigerant-based enclosed air conditioning and vortex tube cooler systems have benefits and drawbacks. Some of the most crucial points to keep in mind when choosing between these two types of enclosure cooling systems include:
性能
? 由于渦流管冷卻器包含的活動(dòng)部件較少，因此其成本通常遠(yuǎn)低于更大、更復(fù)雜的空調(diào)系統(tǒng)。如果維護(hù)得當(dāng)，它們也非常耐用。
? 機(jī)柜空調(diào)提供更高的冷卻性能，通常是高熱負(fù)荷工作時(shí)的更佳選擇。
? 使用恒溫器可以在機(jī)柜內(nèi)保持所需的溫度，而無需冷卻系統(tǒng)持續(xù)運(yùn)行，從而在節(jié)能和延長設(shè)備壽命方面帶來顯著優(yōu)勢(shì)。
環(huán)境
? 渦流管冷卻器和閉環(huán)機(jī)柜空調(diào)不會(huì)讓外部空氣污染機(jī)柜。因此，在需要注意多塵或污染空氣的環(huán)境中，它們是清潔冷卻的理想選擇。
? 渦流冷卻系統(tǒng)用經(jīng)過過濾的壓縮空氣取代機(jī)柜內(nèi)的熱空氣。這可以在微正壓下實(shí)現(xiàn)，確保機(jī)柜得到凈化并與外部環(huán)境完全密封。
對(duì)于極端危險(xiǎn)的應(yīng)用，請(qǐng)尋找具有適當(dāng) NEMA 或 NFPA 70 NEC 區(qū)域等級(jí)的產(chǎn)品。它們專為惡劣條件而設(shè)計(jì)。
操作簡便
? 傳統(tǒng)的封閉式空調(diào)和渦流管冷卻系統(tǒng)都需要一些日常維護(hù)。然而，渦流冷卻系統(tǒng)的維護(hù)成本通常更低。
? 渦流管冷卻器比同類封閉式空調(diào)裝置更易于安裝，占用空間更小，是冷卻設(shè)備空間有限的區(qū)域的理想選擇。
? 渦流管冷卻器需要清潔干燥的壓縮空氣才能高效運(yùn)行。
Performance
? Since vortex tube coolers consist of fewer moving parts, they typically cost much less than the larger and more complicated air conditioning systems. If maintained properly, they are also extremely durable.
? Enclosure air conditioners offer higher cooling performance and are usually a stronger option when working with high heat loads.
? Using a thermostat will allow you to maintain your desired temperature inside the enclosure without requiring your cooling system to run continuously, providing considerable benefits in terms of energy savings and equipment life.
Environments
? Vortex tube coolers and closed-loop enclosure air conditioners do not allow outside air to contaminate the enclosure. Therefore, they are great options for clean cooling in environments where dusty or polluted air is a concern.
? Vortex cooling systems replace the hot air in the cabinet with filtered compressed air. This can be achieved at a slight positive pressure, ensuring the enclosure is purged and perfectly sealed from the outside environment.
For extreme, hazardous applications, look for products with the appropriate NEMA or NFPA 70 NEC Zone rating. They are constructed for harsh conditions specifically.
Ease of Operation
? Both conventional enclosure air conditioners and vortex tube cooling systems require some routine maintenance. The cost of this maintenance, however, is usually lower with vortex cooling systems.
? Vortex tube coolers are easier to install than comparable enclosure air conditioning units and take up much less space, making them a solid choice for areas with little room for cooling equipment.
? Vortex tube coolers require a supply of clean and dry compressed air to operate efficiently.
