Patent ID: 7927464

Claim:
A vapor compression distillation system comprising: a fluid inlet for receiving a fluid that is to be distilled; a fluid outlet for a distillate from the fluid; a heat exchanger comprising a housing and a core surrounded by the housing, the core connected to the fluid inlet and the fluid outlet to transfer heat from the distillate to the fluid; and an integrated motor/compressor unit connected to the heat exchanger to receive vaporized distillate therefrom and to supply pressurized distillate thereto, the integrated motor/compressor unit comprising a compressor wheel and an electric motor including a rotor directly coupled to the compressor wheel to rotate the compressor wheel at the same speed as the rotor, the compressor wheel extending into the housing of the heat exchanger to receive the vaporized distillate from the core and deliver the pressurized distillate to the core.
