Advantages of microchannel technology in low-temperature systems
When using low-temperature cooling and air conditioning systems in cold storage facilities, food processing plants, and industrial freezers, productivity at very low temperatures is a top priority. These systems must maintain stable, often sub-zero temperatures with high humidity, frost, and frequent defrosting. The traditional coil design may not work as optimally under these conditions, resulting in inefficiency, increased maintenance, and shortened equipment life. However, microchannel heat exchangers are a promising alternative, combining improved heat transfer, reduced frost formation, and greater durability.
The biggest advantage of microchannel technology for use at low temperatures is its ability to maintain efficient heat transfer at very low evaporation temperatures. Unlike copper-aluminum coils, which are prone to poor refrigerant distribution and the appearance of hot spots, microchannel coils use flat aluminum tubes with multiple internal channels. This design ensures a uniform flow of refrigerant, which results in a more uniform coil surface temperature. This means that such coils are more efficient both during defrosting and cooling, consume less energy and respond faster to the needs of the system. Learn more.
In addition, the compactness of the microchannel coils provides greater flexibility in the system design. In conditions of limited space in cold storage rooms, …
