Subcooling: Applications, Economizer and energy efficiency & Transcritical carbon dioxide systems

The term subcooling (also called undercooling) refers to the intentional process of cooling a liquid below its normal boiling point. For example, water boils at 373 K; at room temperature (293 K) liquid water is termed "subcooled". Subcooling is a common stage in refrigeration cycles and steam turbine cycles. Some rocket engines use subcooled propellants.
