Subcooling occurs when the vapour

Subcooling occurs when the vapour Correct Answer removes sensible heat from the refrigerant

Concept:

  • The compressed refrigerant vapor travels to the condenser, the condenser is where heat is rejected from the refrigeration system. the high-pressure, high-temperature vapor leaving the compressor undergoes three changes in the condenser.
    1. The refrigerant gives up sensible heat in preparation for condensing
    2. The refrigerant condenses from a vapor into a liquid, rejecting latent heat
    3. After condensing to 100% liquid, the refrigerant subcools and continues to reject sensible heat.
  • Sensible heat is defined as a temperature change that can be measured with a thermometer. You can observe changes in outside temperature. by looking at a thermometer or by opening the window and sticking your head out.
  • Latent heat, on the other hand, is a temperature change that cannot be measured with a thermometer. Latent heat is therefore also referred as "hidden heat".
  • "Subcooling" refers to the amount of sensible heat that is removed from a liquid after it has condensed.
