Hot fridge?

  1. Dec 28, 2006 #1
    1. The problem statement, all variables and given/known data
    Why is the kichen floor around a household refrigerator usually wamer than the floor in other parts of the kitchen?


    2. Relevant equations
    none


    3. The attempt at a solution
    I have seen the refigeration cycle. The places where heat is dissapated is the condenser and compressor. With the compressor, the heat is more the work provided by the motor. With the condenser, the refrigerant is condensed from a gas to a liquid so there is heat outflow but does the heat flow to the outside? If so than that is most likely responsible for the hot floor. The motor is usually at the back of the fridge so should warm the wall against which the fridge is, not the floor. Hence it looks like its because of the condenser. Correct?

    The refrigerator moves heat from inside the fridge and exhausts it out a vent on the front, at the bottom. In addition to the heat it removes from inside, it produces its own waste heat (it is not 100% efficient), and this heat is exhausted from the same vent.

    So I was right about the condenser as the main heat dissapater.
