Superheat and Sub-Cooling Refrigeration HVAC
Superheat and Sub-cooling - In HVAC refrigeration coils and fans are used for air conditioners and heat pumps to transfer heat in one direction or another. A good HVAC technician is well versed in refrigeration. Refrigeration is defined as moving heat from one place to another. Modern air conditioners and heat pumps use a chemical refrigerant used in vapor compression refrigeration.
This chemical refrigerant has great properties for absorbing heat. What makes these chemicals so efficient is the temperature at which they change state or change from a liquid to a vapor and condense back to a liquid again. This is key to understanding superheat and subcooling. (more…)
