Evaporative temperature

  1. Dec 7, 2005 #1
    I'm reading a text about heat pumps here which says that if the outside temperature drops, then the evaporative temperature also drops. This confuses me. I thought the evaporative temperature (at a certain pressure) was a quality within the refrigerant? Can someone explain this to me?

    If the temperature outside drops, the temperature of the refrigerant drops, and therefore the pressure also drops.
