SA-96-09-1 -- Design of Ammonia-Water Condenser

Develops a design model of an ammonia-water condenser in absorption heat pump systems. An ammonia-water mixture enters the condenser through a helically coiled fluted tube as a superheated vapour, cools, and then condenses into a liquid, which is further subcooled.

Condenser - Function & Working - Engineering Insider

In a typical refrigerant condenser, the refrigerant enters the condenser in a superheated state. It is first de-superheated and then condensed by rejecting heat to an external medium. The refrigerant may leave the condenser as a saturated or a sub-cooled liquid, depending upon the temperature of the external medium and design of the condenser.
