Episode: Stacking Liquid vs. Mechanical Subcooling - Short 115
Description: In this short podcast episode, Bryan compares strategies for increasing the subcooling, including stacking liquid and mechanical subcooling. Subcooling is a consequence of condensing; when we change the refrigerant from a vapor to a liquid, it will drop below saturation temperature after it becomes completely liquid. There are three phases in the condenser: desuperheating, condensing, and subcooling. The first few rows of the coil reduce the superheat of the vapor entering the condenser. Once there is no more superheat, heat rejection helps the saturated refrigerant transform into a liquid entirely. Near the end of the coil, liquid...
