Working principle

⁄ A pair of substances (water/Lithium bromide)
is separated through the addition of heat

(Desorption)

⁄ Through the removal of heat they are combined

(Absorption)

⁄ Desorption and Absorption takes place

at different pressures in the vacuum range

⁄ (Desorption: 80 mbar abs.; Absorption: 10 mbar
abs.)

⁄ Cold water can be produced in a range of 6°C to
12°C

⁄ To produce temperatures as low as – 60°C;
Ammonia and Water is used
