Designing Microchannel Condensers for Use withChilled Water Coils
Microchannel condensers are a mainstay of modern HVAC and refrigeration systems, providing a reduced footprint, high performance, and reduced refrigerant usage compared to conventional condensers. When paired with chilled water coils, their design must be given serious consideration in order to enhance long-term operation, system compatibility, and overall efficiency.
Optimizing Heat Transfer
One of the main goals in the design of microchannel condensers is the optimization of heat transfer. The units are designed around flat aluminum tubes with extremely small internal channels and louvered fins for improved thermal performance. This design has the potential to improve heat exchange by up to 40% compared to traditional finned-tube designs. The louvers also reduce air resistance, allowing smaller fans to be used without loss of airflow.
When adding a chilled water coil to the system, its design needs to be compatible with the condenser. The coil typically accepts heat from the air and …
