A common way to obtain subcooling is by using an additional heat-sink cooled heat
exchanger, usually denominated subcooler. Typically, a high-side pressure receiver is
installed between the condenser and the subcooler in order to separate liquid from vapor
before liquid runs through the subcooler. In shell-and-tube condensers, a receiver may not
be necessary since the shell acts as a liquid-vapor separator. One can think of the subcooler
not only as separate heat exchanger but as part of a then larger condenser which has some
