Microchannel coil technology is expected to account for as much as 30%

Recommended Posts

 Microchannel air-side coils, which are a relatively new technology for the process industries, are having a positive impact because their performance exceeds that of traditional copper tube/aluminum fin coils in a wide range of OEM applications. multi port tube have a promising future in a variety of applications including process cooling, process chillers, cooling coils, environmental chambers, and rooftop system air-handling equipment in the long run. Refrigerant condensers (with capacities ranging from 0.5 to 400 tons) and evaporators (cooling coils) are all made of microchannel coils, and fluid coils are used for air-side cooling and dehumidification with micro channel tube.

The automotive industry was the first to use multi port tube, which was approximately 30 years ago. Condensers, evaporators, and radiators were designed with an air-side heat exchanger in mind, but they needed something that weighed (and cost) less than the traditional copper tube/aluminum fin design. In addition to having an air-side fin design, the all-aluminum microchannel heat exchanger coils have a flat-tube design. Several variations of their design have been developed since their introduction into the automotive industry, including radiators, air-conditioning condensers, evaporator/cooling coils, and cabin heaters.

Following its introduction in process cooling and HVAC/R applications in the mid-2000s, microchannel coil technology has progressed to be used in a variety of other applications. Their size ranges from four to fifty times that of the original automotive designs, and they are intended to provide robust performance (as well as less susceptibility to galvanic corrosion) under more demanding conditions while remaining lighter in weight and physically smaller in size. When microchannel coils are integrated into process equipment, they may be able to provide greater energy efficiency while operating at closer thermal approach temperatures.

Process equipment energy efficiency has increased dramatically over the past 30 years, thanks to advancements in compressors, variable-speed fans, and plate heat exchangers, among other things. Microchannel air-side coils, which are used in the process cooling and chiller equipment industries, contribute to the advancement of the technology. Refrigerant condensers, process chillers, environmental chambers, and other compressor-driven systems are among the many applications for which they are used.

A process chiller with mechanical refrigerant cooling systems, in which the micro channel tube are used as condensers, is one example of an application where microchannel air-side coils are assisting in providing energy efficiency benefits to the user. The use of microchannel coil technology is estimated to account for up to 30% of all process chillers in the world, with some industry insiders predicting that this figure will rise to as much as 40% in the next 5-10 years.

The integrally brazed air-side fins of microchannel heat exchangers achieve high heat transfer rates, close approach temperatures, and low air-side pressure drops because of their small cross-sectional area. Reduced compressor horsepower requirements, improved energy efficiency, and increased cooling capacities are the result of this.

The size of all-aluminum microchannel heat exchangers is one of their distinguishing characteristics. In some cases, depending on the design conditions, microchannel coils can have a smaller coil-face dimension than conventional coils, and they are generally thinner. This is critical for manufacturers of process cooling equipment because it has a direct impact on the size and performance of the equipment they produce. Additionally, the smaller size and all-aluminum construction reduce the weight of the equipment and, depending on the size of the equipment, the structural support requirements for the equipment are reduced. Finally, because of their small size, they require less refrigerant, which can result in lower long-term maintenance costs.

Microchannel coils are also designed for use in air-handling equipment such as evaporators and chilled water coils, which are used for a variety of applications including process cooling, makeup air systems, dehumidification units, and high-load cooling in data centers. In addition to these more recent applications, multi port tube for evaporators used in refrigerant-to-air cooling and fluid-to-air water coils are also being used.

    • Wait, Burning Man is going online-only? What does that even look like?
      You could have been forgiven for missing the announcement that actual physical Burning Man has been canceled for this year, if not next. Firstly, the nonprofit Burning Man organization, known affectionately to insiders as the Borg, posted it after 5 p.m. PT Friday. That, even in the COVID-19 era, is the traditional time to push out news when you don't want much media attention. 
      But secondly, you may have missed its cancellation because the Borg is being careful not to use the C-word. The announcement was neutrally titled "The Burning Man Multiverse in 2020." Even as it offers refunds to early ticket buyers, considers layoffs and other belt-tightening measures, and can't even commit to a physical event in 2021, the Borg is making lemonade by focusing on an online-only version of Black Rock City this coming August.    Read more...
