Tubes and Coils

Copper’s efficient heat transfer inside and ‎outside the tube permits a high heat-exchange capacity to be realized in a compact space, especially using small-diameter ‎copper tubes. These factors result in less materials usage yet higher energy efficiency for appliances and equipment. The long service life of copper tube heat exchangers in these HVACR applications ‎is due to the high strength, excellent durability, and corrosion resistance of the copper tubes.

Coil Design

It is possible to begin straightaway designing a heat exchanger from smaller diameter copper tubes. These principles can be used to design a drop-in replacement coil for an existing product, where the space constraints are the same; or they can be applied to a completely new design, for example with a change of refrigerant, to meet performance objectives such as heat exchange capacity or airside pressure drop.

Performance Simulators

The use of simulations has become commonplace in every field of engineering design, including heat exchangers. The mathematics has been available for decades, and now computing power has caught up with the mathematics. Powerful simulation software is widely available to product design engineers. Simulation tools for design engineers have also become easy to use, with menu driven interfaces and 3D visualizations of results.

Copper is strong, durable and corrosion resistant as well as recyclable. These features coupled with the higher efficiency of small diameter tubes make copper the preferred choice for heating and cooling applications.

Small-diameter copper tubes are being developed at an accelerated pace to assist in the attainment of sustainability goals for heating and cooling. Copper is an essential component of sustainable technologies. It plays a key role in decarbonization and electrification.

A key advantage of small diameter copper tubes is that they allow high heat transfer capacity in a compact space, resulting in less material usage and higher system-wide energy efficiency for appliances and equipment. Higher system efficiencies for air-conditioners and refrigeration equipment contribute to decarbonization since less energy is necessary for the same performance results. These features make copper the resilient and sustainable choice for heating and cooling applications.
