Xergy Inc has revealed its first full scale 2.5KW demonstration “Kuel-Cell” electrochemical compressor unit.
Xergy Inc has exhibited its first full scale 2.5KW demonstration “Kuel-Cell” Electrochemical Compressor unit at the DOE ARPA-E Energy Innovation Summit at the National Harbor, in Washington DC.
The device uses water as a refrigerant; using 8 cells (8.5 cm x 8.5cm) configured in series electrically and in parallel for fluid flow.
The demonstration unit features glass domes that can be ‘touched” by observers to feel the hot and cold side of the refrigeration system as well as two pressure gauges on either side of the expansion valve that can provide pressure differential data during operation of the unit.
The “Kuel-Cell” Compressor system operates by pumping protons across an ion exchange membrane between two gas diffusion electrodes.
These protons draw refrigerant (in this case water) with them across the membrane. When the refrigerant reaches the other side of the MEA (membrane electrode assembly) it is released at higher pressure and fed into a refrigeration cycle (as with other compressor systems).
The “Kuel-Cell” Compressor Technology is claimed to be more efficient, motor-less noise-less, modular, scalable, and more reliable than traditional mechanical systems and employs non-CFC refrigerants that do not deteriorate our environment.
