SECTION 2 – PRODUCT DESCRIPTION
HOW IT WORKS
The single effect (hot water driven) absorption chiller
uses deionized water as the refrigerant and lithium bro-
mide (LiBr) solution as the absorbent.
The vapor pressure of the lithium bromide solution is
lower than the vapor pressure of the refrigerant. The
vapor pressure of the LiBr solution is directly related
to the amount of refrigerant (water) present in the solu-
tion with the LiBr and the solution temperature.
