In a recent meeting with Chris Seebach from England, he mentioned a water
|
|
distillation system which used a vacuum to boil the water and provide pure
|
|
water. It is a system being promoted by AquaTech, Mr. Seebach's group in
|
|
Europe. This file provides information that relates to the subject.

JD>Marc,
|
|
> An absorbtion chiller is an absorbtion cooling unit that is used to make
|
|
cold water. The water ("chilled") is then pumped around the building to
|
|
what amounts to radiator units to provide environmental cooling. As in
|
|
Air Conditioning.
|
|
|
|
JD > The chiller operates on the same principle as a kerosene or gas-powered
|
|
refrigerator, using heat to make cold. I've studied the damn diagrams,
|
|
and never really did understand exactly how they work, even though a
|
|
compressor-type is nearly second nature. Someone else here is sure to
|
|
help out with that.
|
|
|
|
Back in my younger days, I was stationed on a submarine. The primary air
|
|
conditioning plant for the submarine was an absorbtion type machine.
|
|
|
|
Pretty simple actually, the interior of the unit was purged of any non-
|
|
condensable gases and very low vacuum was established (close to 0.00 mm of
|
|
mercury as possible). At this low vacuum water will actually boil at close to
|
|
32 degrees fahrenheit.
|
|
|
|
A fresh water system (called chill water) was used to "transport" the cold to
|
|
the ship. The returning "hot" water ran through a heat exchanger inside the
|
|
air conditioner where heat was transferred to the water that existed in the
|
|
low pressure environment. The water boiled and the resulting steam or water
|
|
vapor or whatever was absorbed by a strong concentration of lithium bromide (a
|
|
salt).
|
|
|
|
The diluted lithium bromide concentration went to a different section of the
|
|
air conditioning, was heated by steam thus reconcentrating the lithium
|
|
bromide. The water driven off by that second heating was condensed by a
|
|
seawater heat exchanger. The resulting condensed fresh water was reused to
|
|
cool the chill water water. The process is similar for refrigerators that use
|
|
a heat source, rather than a compressor.
|
|
|
|
Most use a mixture of hydrogen and ammonia, but the process is very similar to
|
|
the method I described above. They certainly are quiet and don't inherently
|
|
require electricity. Don't know about efficiency, though. The air
|
|
conditioner on the submarine was rated for 200 tons of air conditioning,
|
|
whereas a refrigerator is something on the order of 1 ton.
|
|
|
|
As always the standard disclaimers apply. Happy energy transferring.
