Are Your Current Coils Limiting HVAC System Efficiency?
Are your current coils limiting your system’s SEER ratings? Do you need thermal simulation data to win project bids? HVAC and heat pump manufacturers need heat exchangers that support energy efficiency, refrigerant transition, airflow performance, condensation management and stable mass production.
Efficiency Targets & SEER Pressure
Residential and commercial HVAC systems need coil designs that improve heat transfer while controlling pressure drop, airflow resistance and refrigerant charge.
Refrigerant Transition Challenges
R32, R410A and low-GWP refrigerant systems may require different tube structures, refrigerant circuits, coil sizes and pressure considerations.
Condensation & Corrosion Issues
Hydrophilic aluminum fin treatment and suitable surface options can help manage condensate drainage and improve reliability in humid HVAC environments.
Lack of Engineering Data for Project Bids
For OEM projects and commercial bids, buyers often need thermal calculation, CFD simulation support, coil drawings and clear material selection guidance.

CFD Thermal Simulation Support
Domi can support HVAC coil design review through thermal calculation, airflow analysis and CFD simulation planning. This helps equipment manufacturers evaluate heat transfer performance, pressure drop, airflow distribution and coil geometry before sample development.
Simulation methods, report format and available data should be confirmed based on project scope and buyer requirements.
Hydrophilic / Aluminum Fin Treatment Options
For air conditioning and heat pump applications, fin surface treatment can support condensate drainage, corrosion resistance and stable airflow. Domi can discuss hydrophilic aluminum fin, epoxy coating or other surface treatment options based on the working environment.
The exact coating or surface treatment specification should be selected according to application, humidity, corrosion exposure and system design.
Microchannel Condensers for R32 / R410A Systems
Microchannel condenser designs can help reduce refrigerant charge, improve compactness and support lightweight HVAC unit design. For R32 and R410A systems, coil structure, pressure rating, material selection and brazing quality should be reviewed carefully.
Refrigerant compatibility and pressure requirements must be confirmed for each project.
