(57) Abstract :
The present invention discloses a triple-effect absorption refrigeration system (100) comprising a desorber (106) for receiving a
heated LiBr solution having concentrated between 25 - 45 % from a first operation cycle (102) and an absorber (108) for receiving
a cooled LiBr solution having concentrated between 54 - 64 % from a second operation cycle (104). The heated LiBr solution
extracts heat from a fluid to be heated to provide the refrigeration effect. The water vapors generated are absorbed by the cooled
LiBr solution in the absorber (108). The system of the present invention provides higher COP, uses a low temperature heat source,
and alleviates the corrosion problem.
