Innovative heat transfer technology
The patented innovation of microchannel condensers incorporates vertical microchannel tubes to enhance condenser operation, avoid oil return issues, and ensure predictable coil performance. Unlike any other microchannel coils, the lower header serves as a mini-receiver to reduce critical refrigerant charge issues and provide easier system charging. An integral baffle assures proper coil operation and liquid refrigerant return.
Compared to finned tube condenser designs, our microchannel condensers are a robust design with major technical benefits. With proven field experience, we offer many competitive advantages for OEM equipment and new applications.
Equipment designs incorporating advanced microchannel condensers span a wide range of systems designs, including air-cooled chillers, heat pumps, condensers, dry coolers and rooftop systems.
Features and advantages
Advanced microchannel condensers significantly improve HVAC systems performance. The benefits include:
Up to 40% higher efficiency compared to fin/tube designs
Lower airside pressure drop
Closer approach temperatures
Up to 20% smaller coil face and thin design
Less weight (up to 50%)
Less refrigerant charge (typically 40% to 60%)
Built-in mini-receiver is based on a patented method of using the lower manifold to accumulate and hold liquid refrigerant. The lower manifold has an internal outlet baffle to allow only liquid refrigerant to leave the heat exchanger and to hold back any refrigerant gas.
Thus, an excess refrigerant charge is allowed to backup into the lower manifold, and help optimize the system charge and operation. This feature also improves part-load operation and helps reduce critical charging of the system.
Product selection software
MCHE selection software includes condenser, evaporator, heat pump, and water coils making it a complete selection and calculation tool for refrigeration professionals. The software provides selections for microchannel heat exchangers which enables the user to select the best-suited product based on several deciding parameters such as heat exchanger application, cooling capacity, refrigerant, evaporation and condensation temperature, airflow and air temperature and other critical variables in refrigeration systems.
