Revolution of shape and materials
Heat Transfer Coefficient is 3.5 times more than Iron Pipe
The Coefficient of Star Wheel Pipe was 240W/mk,whether Iron Pipe
was 80W/mk
Cold Conductive Area is 20 times more than Iron PIpe
The Radial Shape Fins will enlarge the heat transfer area
Revolution of Defrost-Free System
Without defrosting, saving 20% energy
Without fan motor electricity, saving 10% energy
The increasing conduction area and speed
makes the horsepower of compressor only
needs 30% than traditional one.
