Claim 12:
13. A vapor distillation apparatus comprising:
a source liquid input;
a compressor;
an evaporator condenser apparatus comprising:
a substantially cylindrical housing; and
a plurality of tubes in said substantially cylindrical housing,, wherein an evaporative section is located inside the plurality of tubes and a condenser section is located between the tubes and said substantially cylindrical housing, said source liquid input is fluidly connected to said evaporator section where source liquid is transformed into steam and delivered to the compressor and the said condenser section transforms compressed steam received from the compressor into product water;
a vent valve fluidly connected to the condenser section;
a temperature sensor located in the evaporative section;
a control system for controlling said vapor distillation apparatus comprising at least one controller; and
the control system wherein one of the at least one controllers is a vent controller that is configured to open and close the vent valve and receives a temperature signal from the temperature sensor and wherein the vent controller varies the duty cycle of the vent valve based on the temperature signal and an operating state of the vapor distillation apparatus.
