With a focus on advanced heat transfer mechanics and material optimization, microchannel coils deliver unmatched performance in both cooling and heating applications.
Enhanced Air-Side Heat Transfer
Microchannel coils are engineered with high-density aluminum fins, precisely shaped and spaced to maximize contact with ambient air. This air-side optimization improves the rate at which heat is absorbed or rejected, reducing the overall thermal resistance. The result is faster and more effective air conditioning performance in variable climate conditions.
Superior Conduction Between Fins and Tubes
Unlike traditional round-tube heat exchangers, microchannel coils utilize flat multi-port tubes that allow a wider contact area with the aluminum fins. This design minimizes thermal resistance and enhances conduction efficiency between the fins and the refrigerant pathways. The close fin-tube integration ensures that heat is transferred quickly and with minimal loss.
Refrigerant-Side Optimization Through Multi-Port Channels
Inside each flat tube are multiple microchannels that provide a large internal surface area for heat exchange. This configuration promotes more uniform refrigerant distribution, reduces pressure drop, and improves phase change behavior during evaporation or condensation. The improved refrigerant-side performance is a key factor in achieving 20–40% higher system efficiency over conventional systems.
