| See the feature article, "The Nuances of Nozzle Sizing," to learn how to check the size of the refrigerant distributor nozzles -- and why it matters. |
Enthalpy - Heat content; a term of measurement for how much heat a gas or liquid can hold, and for how much heat is needed to change the temperature.
Expansion Valve Hunting- Alternate overfeeding and starving of refrigerant flow to the evaporator.
Heat Load– An amount of heat that must be removed within a certain period, usually 24 hours.
Homogeneous- Of uniform structure or composition throughout.
Subcooling- Cooling a liquid to a temperature that is lower than the saturation temperature for a given pressure.
Superheat- The difference between the vapor point (i.e., the temperature at which the refrigerant evaporates at a given pressure) and the actual temperature of the refrigerant exiting the evaporator coil.
