机柜空调和涡流管制冷器有什么区别？（中英文）

为封闭式电气柜找到完美的冷却解决方案并非易事。为了为企业做出正确的选择，需要准确的信息和最实用的支持来选择机柜气候控制系统，想知道机柜空调还是涡流管冷却器更适合。以下是一些在选择正确的电气柜冷却方法时需要牢记的重要考虑因素。

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.

解决机柜冷却难题

包含敏感设备的封闭式电气柜在运行过程中会产生极高的热量。机柜或机柜冷却系统可保持电气和电子设备以最佳效率运行，并防止过热导致意外关机或损坏。现代冷却技术的进步使得在运行过程中保持设备冷却变得更加容易，并减少了因过热引起的电气和电子设备故障。

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.

什么是机柜式空调和涡流管冷却器？

涡流管冷却器和机柜式空调均设计用于在封闭区域内工作，以冷却电子设备和其他设备。然而，这两个系统采用截然不同的运行方式。

• 涡流管冷却器将冷压缩空气注入封闭区域，无需运动部件和制冷剂，使其成为独立、耐用且安静的解决方案。

• 机柜式空调的工作原理与传统空调系统类似。该方案需要压缩机、蒸发器鼓风机和冷凝器鼓风机协同工作，将冷空气集中在机柜内并散热。

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.

机柜式空调的工作原理

传统的机柜式空调的工作原理与家用和商用中央空调大致相同：

• 首先，制冷剂气体进入压缩机升温。

• 接下来，制冷剂被输送到冷凝器盘管，冷却后重新变成液体。

• 然后，液态制冷剂被送至蒸发器盘管，吸收热量，使蒸发器盘管显著冷却。

• 风扇引导空气流经蒸发器盘管，冷却蒸发器盘管，并产生冷空气，冷空气分布在整个机柜内。

• 闭环机柜式空调从机柜中吸入热空气，并在热量散发后将其送回机柜，而不会吸入环境空气。这可以保护机柜免受灰尘或有害空气颗粒的侵害，并实现高运行效率。

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.

涡流管冷却器的工作原理

涡流管是涡流冷却器系统的核心。该管将压缩空气压入一个腔室，该腔室使空气以极高的速度旋转，转速高达每分钟一百万转。流动较快的热空气会流到管外，并通过阀门排出。剩余的流动较慢的空气比进入的空气温度低得多，会流入封闭区域。涡流管冷却器系统可将温度降低高达 100 华氏度（约 37 摄氏度）。

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.

优缺点

基于制冷剂的封闭式空调系统和涡流管冷却器系统各有优缺点。在选择这两种封闭式冷却系统时，需要牢记的一些关键要点包括：

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

• 由于涡流管冷却器包含的活动部件较少，因此其成本通常远低于更大、更复杂的空调系统。如果维护得当，它们也非常耐用。

• 机柜空调提供更高的冷却性能，通常是高热负荷工作时的更佳选择。

• 使用恒温器可以在机柜内保持所需的温度，而无需冷却系统持续运行，从而在节能和延长设备寿命方面带来显著优势。

环境

• 涡流管冷却器和闭环机柜空调不会让外部空气污染机柜。因此，在需要注意多尘或污染空气的环境中，它们是清洁冷却的理想选择。

• 涡流冷却系统用经过过滤的压缩空气取代机柜内的热空气。这可以在微正压下实现，确保机柜得到净化并与外部环境完全密封。

对于极端危险的应用，请寻找具有适当 NEMA 或 NFPA 70 NEC 区域等级的产品。它们专为恶劣条件而设计。

操作简便

• 传统的封闭式空调和涡流管冷却系统都需要一些日常维护。然而，涡流冷却系统的维护成本通常更低。

• 涡流管冷却器比同类封闭式空调装置更易于安装，占用空间更小，是冷却设备空间有限的区域的理想选择。

• 涡流管冷却器需要清洁干燥的压缩空气才能高效运行。

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.
