Fluid is a refrigirant and pressurized like in most air conditioners

  1. Jan 22, 2008 #1

    1. i have 2 pipes. the source is pipe A and i will connect it to pipe B. the diameter of Pipe varies and has a range, lets say around 1 in. pipe A can be larger than pipe B. what mechanism shall i i use in order to avoid leakage during the process? the fluid is a refrigirant and pressurized like in most air conditioners (window-type)

    2. i have this evaporator and i want to test its capacity. do i need to have the complete aircon parts (condenser, compressor, expansion device, etc) or just a refrigirant tank, pump and an air source.?

    3. if the test is done, what design shall i use to be sure that there is no refrigirant left in the evaporator and it goes back to the tank?

    1. Your first question is unfinished....

    2. You can't test an evaporator without a functional air conditioning cycle.

    3. Not sure about this one - I guess I always thought a little bit of the gas was lost.

    so, what will i do to minimize the refrigirant left in the heat exchanger?
