The Development of Heat Exchangers for Energy-Efficient, Low-GWP Refrigerant Appliances
Manufacturers are highly motivated to develop heat exchangers that satisfy three often contradictory criteria: low refrigerant-charge, high energy-efficiency and low cost. Smaller diameter copper tube heat exchangers help manufacturers reach all three of these objectives.

Building Better Appliances with Smaller-Diameter Copper Tubes

The “less is more” principle popularized by American inventor R. Buckminster Fuller is especially apt with respect to coil designs for air-conditioning and refrigeration appliances. Demands to increase energy efficiency and lower material costs forces manufacturers to reconsider their coil designs. Also, concerns about the atmosphere are driving manufacturers to reduce refrigerant volumes and minimize the ozone depletion potential (ODP) and global warming potential (GWP) of refrigerants.
