Nordyne earns patent for HVAC construction product
HVAC construction manufacturer Nordyne said it has received a U.S. patent for its defrost process on split-system heat pumps with Micro-Channel condensing coils.
Traditional tube-in-fin HVAC market heat pumps have side coil headers and defrost horizontally, the company says. But with Nordyne’s Micro-Channel heat pump, the coil is rotated 90 degrees, putting the headers are on the top and bottom.
