Mitsubishi Electric’s Aluminum Vertical Flat Tube Design Improves Heat Exchanger Performance by an Unprecedented 40%
Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has developed an aluminum vertical flat tube (VFT) design that improves heat exchanger performance by up to an unprecedented about 40% in heat-pump air conditioners used for heating and cooling.
- Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has developed an aluminum vertical flat tube (VFT) design that improves heat exchanger performance by up to an unprecedented about 40% in heat-pump air conditioners used for heating and cooling.
- The new VFT heat exchanger combines small-diameter flat tubes, arranged vertically and very compactly, and a high-performance refrigerant distributor with a double-tube structure that evenly distributes refrigerant.
- Compared to conventional aluminum horizontal flat tube (HFT) heat exchangers, Mitsubishi Electric’s new VFT heat exchanger also reduces refrigerant charge thanks to about up to 20% smaller internal volume compared to HFT designs.
- While traditional heat-pump air conditioners use fluorocarbon refrigerants that contribute to global warming, reducing the refrigerant charge tends to lower heat exchanger performance.
