You don’t have to reinvent the wheel. — At some point, you’ve heard, or perhaps said, this phrase. — However, reinventing the wheel may be an ironic cliché, as it’s not clear when the wheel was actually invented. Internet citations suggest the wheel was first crafted in Slovenia more than 5,100 years ago.

The International Copper Association refers to round-tube, plate-fin (RTPF) coils made from smaller-diameter copper tubes as MicroGroove technology.

The function of coils in heating and cooling systems is to transfer heat from one medium to another, either extracting heat from a building and expelling it outside or vice versa. Depending on the application, different technologies are available to ensure thermal energy is transferred as efficiently and cost-effectively as possible.

FIGURE 1: Condensing temperatures and pressures will vary with coil surface area size and EER, just as evaporator temperatures and pressures will.
