Abstract
A fresh water recovery system includes a solar heated evaporator and a heat exchanger operating in a waste heat recovery mode for recovering fresh water from a salt water supply.
Claims1
A method of recovering fresh water from a salt water supply, the method comprising the steps of:
- providing an evaporator configured to receive solar energy;
- providing a counterflow heat exchanger having a hot side and a cold side;
- transferring salt water to the evaporator via a cold side flow of the counterflow heat exchanger;
- transferring fresh water to a fresh water storage tank via a hot side flow of the counterflow heat exchanger;
- condensing vapor from the evaporator while heating salt water being supplied to the evaporator;
- recovering one or more of a salt in solution and a salt not in solution from the evaporator;
- providing a heat exchanger tube;
- exchanging heat between isolated hot side and cold side flows contained by the tube;
- providing a heat exchanger tube divider across which heat exchange between the hot side and cold side flows takes place;
- and
- configuring the heat exchanger tube divider such that it has an area greater than that of a planar tube divider.
