Refrigeration Loop question

  1. Aug 9, 2011 #1
    1. The problem statement, all variables and given/known data

    I have just done a lab with a refrigeration loop, and I'm unsure of which pressures correspond to which parts of the loop. The hand out says to assume the pressure across the condenser and evaporator are constant, and to use the two pressure guages to measure the pressure. Where I'm confused is it says to use the pressure reading after the expansion valve for the condenser, and the pressure upstream of the expansion valve for the evaporator.

    Is this the wrong way around? Intuitively it seems wrong, and the tutor running the lab was unsure as he was filling in for the normal tutor.


    2. Relevant equations



    3. The attempt at a solution
