microchannel coils are more efficient at transferring heat
micro channel tube were first used in the automotive industry approximately 30 years ago, which makes them a pioneer in the field. They needed something that weighed (and cost) less than the traditional copper tube/aluminum fin design, so they used an air-side heat exchanger in their condensers, evaporators, and radiators. The flat-tube design of the all-aluminum microchannel heat exchanger coils, in addition to having an air-side fin design, makes them unique. Since their introduction into the automotive industry, several variations of their design have been developed, including radiators, air-conditioning condensers, evaporator/cooling coils, and cabin heaters.

As a result of its introduction in process cooling and HVAC/R applications in the mid-2000s, microchannel coil technology has advanced to be used in a variety of other applications. These engines are four to fifty times larger than 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 than the original automotive designs, respectively. In process equipment, aluminium micro channel tube may be able to provide greater energy efficiency while operating at temperatures that are closer to the thermal approach temperature.

Efficiency gains in process equipment have been significant over the past 30 years, thanks to advancements in compressors, variable-speed fans, and plate heat exchangers, to name a few examples. Microchannel air-side coils, which are used in the process cooling and chiller equipment industries, make a significant contribution to the advancement of technological advancement. Many different applications for compressor-driven systems can be found, including refrigerant condensers, process chillers, environmental chambers, and other compressor-driven systems.

This is an example of an application where microchannel air-side coils are used as condensers in a process chiller with mechanical refrigerant cooling systems. This is an example of an application where microchannel air-side coils assist in providing energy efficiency benefits to the user. Industry insiders predict that the use of microchannel coil technology will account for up to 30% of all process chillers in the world within the next 5-10 years, with some predicting that this figure will rise to as much as 40% within that same time period.

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

One of the distinguishing characteristics of microchannel heat exchangers made entirely of aluminum is their small size. micro channel tube can have a smaller coil-face dimension than conventional coils in some cases, depending on the design conditions. They are also generally thinner than conventional coils in most cases. Because it has a direct impact on the size and performance of the equipment that manufacturers of process cooling equipment produce, this is critical information for them to have. Aside from that, the equipment's smaller size and all-aluminum construction help to reduce the weight of the equipment, which in turn reduces the structural support requirements for the equipment, depending on its size. In addition, because of their small size, they use less refrigerant, which can result in lower long-term maintenance costs.

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