New rules dictating energy usage in walk-in coolers and freezers (WICF) will become law Sept. 7, according to a recently published final rule, courtesy of the U.S. Department of Energy (DOE).
The energy conservation standards, which were published in the Federal Register on July 11, will set regulations for several classes of WICF refrigeration systems, including low-temperature dedicated condensing refrigeration systems and both medium- and low-temperature unit coolers.
