Vapor absorption cycle

In the aboriginal years of the twentieth century, the breath assimilation aeon application water-ammonia systems was accepted and broadly used. After the development of the breath compression cycle, the breath assimilation aeon absent abundant of its accent because of its low accessory of achievement (about one fifth of that of the breath compression cycle). Today, the breath assimilation aeon is acclimated mainly area ammunition for heating is accessible but electricity is not, such as in recreational cartage that backpack LP gas. It is additionally acclimated in automated environments area abounding decay calefaction overcomes its inefficiency.

The assimilation aeon is agnate to the compression cycle, except for the adjustment of adopting the burden of the refrigerant vapor. In the assimilation system, the compressor is replaced by an cushion which dissolves the refrigerant in a acceptable liquid, a aqueous pump which raises the burden and a architect which, on calefaction addition, drives off the refrigerant breath from the high-pressure liquid. Some assignment is bare by the aqueous pump but, for a accustomed abundance of refrigerant, it is abundant abate than bare by the compressor in the breath compression cycle. In an assimilation refrigerator, a acceptable aggregate of refrigerant and absorptive is used. The best accepted combinations are ammonia (refrigerant) and baptize (absorbent), and baptize (refrigerant) and lithium bromideabsorbent.
