Cold Room Condensing Unit, Solar Direct Drive (SDD)

JUNDE's solar variable-frequency condensing units integrate cold-room refrigeration with photovoltaic direct-drive technology. The fundamental concept is straightforward and unconventional: The inverter compressor and fans are directly powered by DC power from the solar panels, without the need for an inverter stage to convert it to AC. By eliminating this conversion, the system is transformed into a solar direct-drive refrigeration system, as opposed to a conventional cool room that is affixed to a solar array. The range is designed to accommodate a variety of cold-room sizes, stored products, and temperature requirements, spanning from 3HP to 12HP. It is particularly advantageous in cold-chain logistics centers, agricultural-product storage, fruit and vegetable preservation rooms, food cold storage, and quick-freeze rooms. It is most advantageous when the solar resource is robust, and the grid supply and demand are unbalanced.
