HVAC heat exchanger coils
Heat exchanger coils benefit from smaller diameter copper tubes
The International Copper Assn. (ICA) has announced a heat exchanger coil technology that benefits from smaller diameter copper tubes. Heat transfer from the refrigerant to the tube wall is more effective inside copper tubes with diameters smaller than the conventional diameter. Consequently, coils can be made less bulky and air conditioners with higher energy efficiency can be made smaller and lighter. Coils made of conventional copper tubes are a proven technology with a long, successful, field-tested history. The new coils provide the high durability and performance that is expected from copper tubes but they use less raw material.
